While price-performance may be increasingly important during a recession, it is difficult, no matter how great, for a new product to beat not buying anything for saving money. This site uses Akismet to reduce spam. The ThunderX3 is the CN110XX variant, which has 96 cores running at 2.2 GHz with a turbo boost to 3 GHz with a 240 watt thermal design point. x86-64 Assembly - Sum of multiples of 3 or 5. The point that Nuvia is trying to make though is that it does this while using about 30% of the power, a bit over 4W/core for the A13, a little less than 16W for Ice. wmf 1 hour ago. When it is outperformed by x86 … The Next Platform is published by Stackhouse Publishing Inc in partnership with the UK’s top technology publication, The Register. That said, assuming that they are implemented using the same semiconductor process, is ARM inherently more efficient than x86? The new Apple processor is based on the ARM architecture instead of the X86 used by both AMD and Intel. I’m less interested in benchmarks from any processor makers as the fine arts of compiler flags setting and cherry-picking of benchmarks is well developed. And IP does make its way into the market via acquisitions and outright selloffs or licensing. And even if the threads are ignored and a virtual machine is allocated to a core, AMD Epycs top out at 64 cores, or a 50 percent advantage to Marvell, and Intel really – for all practical purposes – tops out at 28 cores or a 3.4X advantage. And I think the fan-cooled m1 in the macbook pro is in a very similar power bracket as the amd ryzen chips. With a properly designed microarchitecture, is it possible for an x86 processor to deliver the same performance per watt as an ARM processor? Clearly, in this benchmarketing work of fiction, none of this is true. Why is this gcd implementation from the 80s so complicated? But the actual server market clients purchasing decisions holds more weight than benchmarks and what workloads are the products being used for. Compared to Intel processor, ARM CPU also supports technologies such as Neural Engine to make ARM Mac a good choice for machine learning. It goes down strongly as negotiating power of the customer increases (i.e. The company’s press release says very specifically that Apple’s new chips will “give the Mac industry-leading performance per watt,” and that’s a very deliberate turn of phrase. As I said in my original post: hype, marketing and flat-out lies. These are compared to 28-core Intel Xeon SP 8280 Platinum at 205 watts and a 64-core AMD Epyc 7742 at 225 watts. Can you really always yield profit if you diversify and wait long enough? Working backwards from this chart, then the Ampere processor with 80 cores has about 4 percent more integer oomph, or about 289.6. Lots of people are blown away, by performance of M1, but are they? As far as servers go, AMD, with its Epyc processors, is going to perhaps be the biggest beneficiary because it is the easiest drop-in replacement for the much more expensive Xeon SP processors from Intel. Let’s look at whole market; client base station, cell network, network edge, metro edge, data center processing, aggregation, switch and route; public, private, enterprise, government communications, telecommunications, packet processing and inspection, security, switch and route, long haul carrier network and control; rural, suburban, urban spoke and hubs, network computing, HPC and supercomputing. We noticed a certain amount of chatter out there after we published some feeds and speeds on the ThunderX3 chip and claims of the performance per core that Marvell thinks it will get with the Triton chip compared to the future “Ice Lake” Xeon SP chip due later this year. Maybe it will be a V-shaped recession that falls fast and recovers almost as fast, and maybe it will be a sharp drop and a much more prolonged climb back to normalcy. We also ginned up what the 180 watt Altra part might look like based on some very serious guessing. Save a few bucks or do something edgy and exciting and cost your business millions extra every year in software licensing. The idea that arm processors are more efficient is a bit of a myth - they've made a different set of tradeoffs (power efficiency over raw speed) and are moving in a different direction and a different set of tradeoffs in an attempt to go after the server market. Most of the power use isn't the processor either - the anandtech article I linked tends to suggest that maybe 1/4 of overall power use is the processor, and that a clovertrail atom uses slightly over half of the ARM processor in a surface. Across network communication and data processing, observing incumbents x86, ARM and Power, how incumbents and challengers are tapering into existing infrastructure, building out into new opportunities, there’s product category, market and volume potential for everyone. It is hard to say, but that gap could close up. There have been desktop systems with ARM CPUs in the past - look up Acorn Archimedes. The clients do their own evaluations so their results hold the most weight above any other’s truly scientific third party testing with the processor makers results always in question(including any sponsored testing under NDAs/Strings attached). It will also have a small memory bandwidth advantage over the Rome chips and certainly some over the current Cascade Lake chips, but probably not on the future “Ice Lake” Xeon SPs Intel is planning to get out this year. In computing, performance per watt is a measure of the energy efficiency of a particular computer architecture or computer hardware.Literally, it measures the rate of computation that can be delivered by a computer for every watt of power consumed. Maybe as the custom ARM ISA based designs get more of the server TAM others will begin offering up solutions. OpenPower’s costs(Licensing/other) must be somehow limiting its adoption in the server market place but OpenPower/power9 home servers can be purchased and the entire processor firmware/software stack is open source as well. Companies: #arm #intel #tsmc. Is it possible to run an x86 binary on an ARM processor? By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. In how many ways can I select 13 cards from a standard deck of 52 cards so that 5 of those cards are of the same suit? And hardware that can be bought by anyone. x86 can afford to go low because it can recover its NRE costs in other markets (desktop, laptop). And the whole point of these SPEC requirements is that the claimed results must be repeatable and reproducible by anyone. I do not expect that AMD would sit on any IP that it has in its portfolio if that custom ARM competition began to make greater inroads against x86. ARM has very good performance per watt, so is particularly suited to mobile/embedded systems. ... it's important to look at performance per watt. By the way, Intel yields 4.64 per core at the GCC level, and AMD yields 4.35 per core compared to 3.62 per core for Ampere Computing. Supply is key and lacking supply business can stall. Read more…, The Serendipitous AI System And Cloud Builder, IBM Leverages Cloud To Push The Encryption Envelope, CentOS And HPC: It’s Okay, We Are Moving On, we think that IT technology transitions are accelerated by such trying times, the upcoming “Quicksilver” Altra processor from Ampere Computing, the upcoming “Triton” ThunderX3 processor from Marvell, 28-core “Cascade Lake” Xeon SP 8280 Platinum chips, SPEC integer benchmark result is here for a Dell PowerEdge MX740c, Looking Ahead To Marvell’s Future ThunderX Processors, Oak Ridge Trials Arm-GPU Combo On HPC Testbed, https://s.dou.ua/storage-files/1_SPECrate2017_int_Fixed.PNG. Asking for help, clarification, or responding to other answers. Take a gander: Now let’s get down to the X86 comparisons. Really, the circumstances behind these submissions are the exact opposite of “minimizing hype, marketing, and flat-out lines. There are extremely well known reasons why people choose not to compare directly to results from SPEC.org, because the specialized compilers that are rolled out for those results have coded tricks built into the compiler themselves to target individual SPEC benchmarks. A few things before we begin. At roughly a quarter the performance of world-leading x86 and ARM mobile processors, the Micro Magic CPU doesn't sound like much yet. Do studs in wooden buildings eventually get replaced as they lose their structural capacity? Apple says that the M1 offers the highest performance per watt, with double the performance of an x86 laptop CPU when running at 10 watts—and one quarter the power draw of an x86 … What we do know is that the system under test had two Altra processors running at 3.3 GHz turbo boost speed and that they were running the SPEC integer test with the GCC 8.2 compilers with the Ofast, LTO, and jemalloc options turned on. Thanks for contributing an answer to Super User! So loads of ongoing IP acquisition and bigger interests buying up smaller interests. Why NASA will not release all the aerospace technology into public domain for free? But as far as the Custom ARM ISA based market is concerned things are getting interesting but any comparisons of ARM and SMT4(ThunderX2) needs some core to core ThunderX2 to Power9(SMT4 variant) comparisons as well just to give some overall basis for comparison. The AMD Epyc 7702 server has a similar configuration, and the two Intel machines assume twelve memory sticks because they only have six memory controllers per socket. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. But what the tests are really comparing? List price is largely meaningless. And AMD is just ticking along nicely, concerning itself primarily with performance-per-dollar and performance-per-watt efficiencies. It would have been useful if Marvell had provided absolute rather than relative performance here. Food for thought: Geekbench 5 - singlecore - … Then again, implementing this translation layer requires additional silicon space on the chip... That said, assuming that they are implemented using the same semiconductor process, is ARM inherently more efficient than x86? It’s just convenient because with SPEC people know at least exactly what the version of exactly whicb application code is being run, since it doesn’t change. Can a True Polymorphed character gain classes? In particular, I would not want to be a company counting on sales of a new computer architecture in the present economy. rev 2020.12.18.38240, The best answers are voted up and rise to the top, Super User works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us. Marvell, as we said, is providing some performance data as well, although it is of a different type but is consistent with the kinds of data that Cavium has provided in the past as it launched the ThunderX1 and ThunderX2 processors. Scenario 2: Apple builds an ARM CPU that’s dramatically faster than x86 CPU, both in terms of performance and power-per-watt. So, our attitude is that all CPUs should run the standard tests on GCC since it is supported equally well (or poorly depending on how you want to look at it) on all CPUs, and then each vendor should trot out their optimized compilers to show the uplift they get on these microbenchmarks and other systems level software such as databases and then the actual workloads should be tested. What this chart says is that basically for every dollar that you spend on a rack of servers using a pair of Xeon SP 8276 processors, you will get nearly four times as performance using a rack of the 180 watt Altra processors, and the multiples are 1.63X compared to a rack of systems based on the much more reasonably priced Xeon SP 6238R processors and 1.41X that of a rack of systems based on the aggressively priced AMD Epyc 7702 processors. What did I leave out? We aren’t talking about Windows Server and a bunch of third party applications running on VMware virtualization here. And yet another “datacenter expert” article that forgets the key piece of the puzzle: that most data center apps are licensed annually by the core, and both ARM and AMD need more cores to do the same work as an Intel CPU. As we said in the article, this is a baseline performance run with standard flags, and we think it is not only absolutely valuable to have this consistent compiler substrate running across generations and architectures, we also think people have a very good sense that for a lot of workloads, the ICC compiler delivers somewhere around 20 percent more performance on a wide range of workloads. What is the performance per watt for Graviton vs Intel? The Apple M1 is an 8 Core processor that offers 4 performance cores and has 4 efficiency cores that ensure high peak performance and lower battery drain. Why were early 3D games so full of muted colours? SMT4 is more of the same. Based on all of these different SKUs and data points, here is a summary table that adds it all together, including the GCC performance estimates: Based on the idea that Ampere Computing has to offer at least a 20 percent price/performance advantage at the chip level compared to the best that Intel and AMD can throw at the cost per performance per watt equation that dominates the buying decisions of the hyperscalers and cloud builders that Ampere Computing is targeting. However, Intel Atom processors deliver very good performance relative to their power consumption as well. Would like to see performance comparison of graviton2 vs altra vs thunder x3, the real situation is completely different Sure, more threads means more throughput, but we’ve been there in the past with Calxeda and others who stitched together weak ARM cores to maximize throughput. You have evidently led a very sheltered life - there are many more processor architectures than just x86 and ARM. Arm doesn't make their own silicon - they design and test it, and sell the IP to make processors. You would have a lot more credibility if you didn’t contradict yourself within two consecutive paragraphs. > SPEC workloads are only meaningful if submitted to SPEC.org [ … ]. Recently there was some discussion in the WCG Ebola thread about using ARM-based hardware for crunching. The recent benchmarks of the Neoverse N1 Graviton2 instances as well as the marketing information discussed above in this blog definitely make me think ARM has caught up with Intel and AMD in performance and surpassed both in cost effectiveness. Comparing performance per megahertz, x86 is 4% - 8% faster than ARM or MIPS. No one is suggesting that anyone buy machines based on vendor competitor analysis, which would be utterly stupid. Neither design is inherently better at everything than the other. It was only a matter of time really before ARM processors started nipping at Intel's low end. What makes ARM "better" than x86 really has more to do with market forces than raw performance. That is correct. Replacement is inevitable. large OEM/ODM, hyperscale). This gives ARM Macs “industry-leading performance per watt and higher performance GPUs", enabling developers to write more powerful and high-end apps and games. How to lock a shapefile in QGIS so only I can edit. That brings us to the last chart in the deck from Ampere Computing, which shows the performance per total cost of ownership deltas between the four chips shown below: This is a system level comparison and the rack of servers using the Altra processors are using a pair of those 180 watt parts (which we estimated some feeds and speeds for) plus sixteen 16 GB memory sticks (256 GB of memory), a pair of Ethernet NICs, a 1 TB SATA drive, and base components like baseboard management controllers, power supplies, and such. In relation to current processor developments Scalable secondary ‘hand me down’ value is suspect. x86 is hamstrung to 4 because of legacy. Are popular benchmarks valid comparisons of architectures? AWS introduced Graviton2 at Re:invent 2019 and is based on ARM Neoverse N1 cores, which scale from 8 to 16 cores per chip and 128 cores per socket in server architectures. ... but it does pour cold water on the idea that ARM is ready to take on x86 for general server compute, though no doubt there are niches where it can do well. How does ARM Cortex A8 compare with a modern x86 processor. Ampere Computing has created a TCO tool that does all of this math, presumably with a lot of servers and different CPU SKUs. The workloads are just workloads, which may or may not be representative of workloads that customers actually care about. It is not really possible to easily guess what these system comparisons might be that Ampere Computing had in its TCO tool, but we look forward to playing with that TCO tool when it becomes available. We have reviewed the upcoming “Quicksilver” Altra processor from Ampere Computing and its future roadmap two weeks ago and also reviewed the upcoming “Triton” ThunderX3 processor from Marvell and its future roadmap this week. Ampere should really not be highlighting the top-end SKU. Capital gains tax when proceeds were immediately used for another investment, Short story about creature(s) on a spaceship that remain invisible by moving only during saccades/eye movements. Real question on my mind is when ARM reaches parity with x86 across the board are the higher end ARM chips going to be able to match something like the Intel i7 and AMD Ryzen 7 in performance per watt. To learn more, see our tips on writing great answers. Intel/AMD have just to price it around the same Cavium is offering, and that’s the end of that. (AMD has the ‘anyone but intel’ market covered solid). Of course its possible. for example https://s.dou.ua/storage-files/1_SPECrate2017_int_Fixed.PNG. Business will hum along, choice returns, industry and society will be better for it. That being said, I also wouldn’t really approve of these fixed scale factors. No-one explains how or why this normalization was done in the first place. This gets us started on the process of thinking about how these different chips might stack up to each other. What is annoying about what Ampere Computing has done in the following charts is that it is comparing different AMD Epycs and different Intel Xeon SPs with its Altra, and in some cases – as with the cost per total cost of ownership of a rack-scale cluster of servers – it is using a lower-bin Altra part in that comparison. Take a look at the whole market; client base station, cell network, network edge, metro edge, data center processing, aggregation, switch and route; public, private, enterprise, government communications, telecommunications, packet processing and inspection, security, switch and route, long haul carrier network and control; rural, suburban, urban spoke and hubs, network computing, HPC and supercomputing. Power efficiency / performance-per-Watt tests were not conducted due to the remote ARM testing. In what way would invoking martial law help Trump overturn the election? Ampere Computing then normalized this to GCC by multiplying by 83.5 percent, which it reckons is the ratio between AOCC 2.0 with the base options and GCC with the above-mentioned options. You cited one of the significant contributors to performance - the 8-wide decode. And as you can see, systems based on the ThunderX3 are expected to have an advantage over the Rome chips on key HPC workloads. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. In relation to current level of network performance which is key to data center growth, network always comes first, as PAM 4 rolls out over the top, switch throughput in the middle, 5G from the edge existing compute infrastructure will be displaced quickly on new network communications and standards (programmable) and hard data processing replacements, light and heavy loads, specialties acceleration, better and best fit for use. As you can see from the numbers on that article - Atom processors designed for mobile devices already match ARM processors on the power efficiency front - so its probably worth wondering why they arn't more common. Marvell is doing adjustments from the ICC and AOCC compilers to GCC where necessary and using the GCC compilers where possible to normalize everything to GCC performance levels across these architectures. CISC and VLIW, and instruction and opcode. By using our site, you acknowledge that you have read and understand our Cookie Policy, Privacy Policy, and our Terms of Service. Why does air pressure decrease with altitude? The first thing that Marvell wants everyone to ponder is just how many virtual machines each one of its processors can host. How to respond to a possible supervisor asking for a CV I don't have. There is no doubt that companies are going to be even more aggressive in measuring the performance per dollar and performance per watt on every piece of hardware that will still need to go into datacenters in the coming days, weeks, and months. The pricing on such a chip, we think, would be even more aggressive and go after the belly of the Xeon SP market: Those aptly named Gold processors, like the new Xeon SP 6238R. There’s also a fair amount of ‘fiction’ (for the want of a better word) in the cavium slides. (Ampere Computing and Marvell are giving some hints on price/performance, which we can work backwards to get an initial price for at least a few SKU in their respective lineups. There's no way to know the power consumption of stuff in AWS. The reality was, and is, that 1T performance is paramount, SMT is gravy on top. In many tests, the CPU shows consistently higher results than x86 CPUs when measured in terms of performance per watt. Let’s start with Ampere Computing and how it thinks its first generation Altra chip will do against the competition in the datacenter, beginning with SPECrate 2017 Integer tests: The Ampere Altra chip tested is presumably the 80-core version; it’s not clear. At this time beginning now and into the next 60 months, the total available market for processors of all types supporting existing infrastructure and build out exceed 1.5 trillion units of Xeon in use. CISC x86 compared to RISC ARM is just not enough and as far as Price/Performance, as Torvalds commented on that price/performance metric once, it’s not about Price/Performance as much as it is about that Price to a customer’s specific-workload’s performance that matters most. x86 vs ARM: Leakage Current Leakage current became a significant contributor to power consumption in 2003 with the move from 0.18 to 0.13 micron feature sizes, and has become more significant in each subsequent generation. Here is the relative performance of these three processors, further normalized against the Epyc 7742 chips (meaning, their performance is set to 1.0 and the others are reckoned against this): The top-bin ThunderX3 has some to a lot of performance advantage over the Epyc and sometimes the Xeon SP chips do better than the Epycs. Where we can find link for test for this results? These pseudo-benchmarks that vendors publish outside SPEC.org aren’t worth one cent. We realize fully that any vendor claims about performance have to be taken with a grain of salt – sometimes a whole shaker – but we also know that server buyers need to have at least a baseline idea of the performance of processors before they can even figure out what processors to test for their workloads. Also maybe the custom ARM server folks with the highest core counts and SMT capabilities should also look at testing out 3D rendering CPU workloads as well and some workstation intensive testing in addition to server workloads. In the end, people are blown away not so much by performance, but by performance per watt. It only takes a minute to sign up. This chart talks about watts per core comparisons of the same processors: The cores are less oomphie in the Ampere Altra chips than in the Epyc or Xeon SP processors, so it is no surprise that the watts per core is lower. Tags: #20nm #28nm #arm-vs-x86 #cortex #cortex-a8 #cortex-a9 #cortex-m0 #fab #low-power #performance-per-watt #smartphone #x86. It’d be better if they just ran benchmarks with the same neutral non-cheating compilers with the same flags on both their chip and whichever competitors they are comparing with. It also shows an interesting alternate viewpoint - to optimise systems per component for power use (as an aside - its entirely possible that you can get pretty significant power savings doing this off a standard desktop platform as well). The seesaw mobile processor battle between ARM and Intel continued at Computex, with ARM claiming it offered better performance per watt for mobile devices than Intel's upcoming chips. In this way, you can see the full spectrum of platforms and tunings and how it might be correlated in the past and in the future with actual applications. Your email address will not be published. Unfortunately, a lot of them are microbenchmarks that have had their compilers tweaked to run things like the SPEC tests and others at peak efficiency and that may not be reflective of the baseline performance that a lot of actual applications will see. So all the custom ARM cores developed need to be looked at and even those that may have never made it fully to market or where to market but discontinued. You just have to look at the Haswell products to understand Intel is serious about power consumption in their products. This kind of basic information that the chip makers present is just the beginning of a long process. reply. And while the Arm server chip upstarts, Ampere Computing and Marvell, were not planning for a global pandemic when they timed the launches of their chips on their roadmaps, they may be among the beneficiaries of the budget tightening that will no doubt start at most companies – if it hasn’t already. Supply is key and lacking supply business can stall. More significantly, this table suggests ARM and MIPS have 40% - 50% better energy per MHz and their size is a factor of 3X to 4X smaller than x86. The SPEC integer benchmark result is here for a Dell PowerEdge MX740c based on a pair of these CPUs. The gap is so large, previous non … It is not directly related to x86 vs arm. What did I leave out? Xeon (x86) Cascade Lakes has been just good enough to keep business, data processing, production operations and communications up and running, this generation of infrastructure, on Intel’s ability to supply incumbent use concerned with keeping product market and financial share and business humming along. I expect that it can produce a 100-150W part that is higher perf and per/watt than its comparable x86 competition and that is where the real draw of the ARM many-core design can be. There seems to be some weird notion amongst certain corners of the internet (and I can suspect the origin of these) that SPEC workloads are only meaningful if submitted to SPEC.org, when that’s a fairly silly notion. ARM executives say its Cortex-A15 and A7 processors offer more performance per watt than Intel's upcoming Atom chips based on Silvermont By Agam Shah U.S. How does a Raspberry Pi 4 truly compare against a modern desktop CPU? It offers in-depth coverage of high-end computing at large enterprises, supercomputing centers, hyperscale data centers, and public clouds. As such, the ISA as presented to the programmer is little more than an interface to issue commands to the processor, rather than a representation of the actual low-level operations the chip performs. This machine had a base SPEC integer rating of 342, which after a conversion to estimated GCC results by multiplying by 76 percent yields 260 and that works out to 130. On most phones, for example, your display is probably taking up close to half your total power use. “ARM platforms will shortly make it through to 20nm in the coming year, where the performance per milliwatt advantage will grow.” Wen said that ARM does not see Intel’s Haswell being able to work in tablets because of its inability to fit into the thermal and power constraints of … Long story short: People say the move from intel x86 to arm is monumental and a huge technical breakthrough. In addition, having studied computer architecture, it is my understanding that in modern processors, the complex x86 instruction set architecture (ISA) is internally translated into simpler micro-operations that use an internal instruction set that is closer to the simpler ARM or MIPS ISAs than x86 proper. Nobody is claiming those comparisons to be the be-all and end-all, there’s a reason other workloads are shown too. Remember, I'm looking for a well-written technical answer in the spirit of Stack Exchange and not mere speculation. Here is another interesting chart from Marvell that talks about the effect of simultaneous multithreading (SMT) on various workloads. Super User is a question and answer site for computer enthusiasts and power users. From my personal experience with my tablet, and from the benchmarks and articles I've read, it always seems ARM processors, as seen in virtually all mobile devices, deliver incredible performance for the amount of power they consume. We could have had more fun with math. We aren't at the beginning of the story with ARM for performance, but ARM certainly isn't nearly as hamstrung out the gate by the legacy of x86 … Featuring highlights, analysis, and stories from the week directly from us to your inbox with nothing in between. You have to start somewhere to get evaluation machines to run actual performance benchmarks on real workloads. Be careful with interpreting web search latency as gauged by Elasticsearch – lower is better, not worse in that part of the chart. So that gives that two-socket machine an estimated rating of 557 and therefore each Epyc 7742 processor a rating of 278.5. And the OS/Software and firmware ecosystem plays an even greater role in making any server hardware offering successful, and that includes OEM Partner support as well. Intel on the other hand, is effectively segmenting modern atom designs into server parts, desktop parts (like new pentium models) and phones, to go after the low end.
