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. x86-64 Assembly - Sum of multiples of 3 or 5. 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). But it is also the ante to even be part of a CPU buying decision. What did I leave out? 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. large OEM/ODM, hyperscale). 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. In this article we are just looking at the raw performance for these x86_64/ARM/POWER9 servers using various tests that operate well cross-architecture. 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. Correspondent, IDG News Service 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. Making statements based on opinion; back them up with references or personal experience. So is price, and we can’t really do a full analysis of Arm server chips compared to X86 until the products actually roll out and we see the prices, too. We also ginned up what the 180 watt Altra part might look like based on some very serious guessing. Overall on paper Falkor looks very competitive. And IP does make its way into the market via acquisitions and outright selloffs or licensing. No one is suggesting that anyone buy machines based on vendor competitor analysis, which would be utterly stupid. The new Apple processor is based on the ARM architecture instead of the X86 used by both AMD and Intel. We could have had more fun with math. Everyone seems to want to normalize their results to some arbitrarily-chosen imaginary constant. Comparison above excludes for no good reason (except if trying to “prove” something that isn’t true) AMD CPUs with best price performance ( 7352, 7402 and 7452 and 7702P ) any of which have price/performance better than Ampere Altra even when using rather strange metrics used. 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. These are ‘optimizations’ that would never be seen in real software in practice (see. Power efficiency / performance-per-Watt tests were not conducted due to the remote ARM testing. You cited one of the significant contributors to performance - the 8-wide decode. Comparing performance per megahertz, x86 is 4% - 8% faster than ARM or MIPS. 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. It is hard to say, but that gap could close up. 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. At roughly a quarter the performance of world-leading x86 and ARM mobile processors, the Micro Magic CPU doesn't sound like much yet. In theory a Falkor core can process 8 instructions/cycle, same as Skylake or Broadwell, and it has higher base frequency at a lower TDP rating. Rosetta translates applications from x86 to Arm. If a vendor wants to publish SPEC2017 results for their chip, they should publish them at SPEC.org. It was only a matter of time really before ARM processors started nipping at Intel's low end. And hardware that can be bought by anyone. The question we have is how ThunderX3 will match up against the “Milan” Epyc 7003 family of chips shipping later this year as well. Featuring highlights, analysis, and stories from the week directly from us to your inbox with nothing in between. Mobile ARM processors for heavy 3d tasks? 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. Particularly in a recessionary climate like the one that we are very likely entering. It is pretty clear at this point that there is going to be a global recession thanks to the coronavirus outbreak. 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. Its probably fairer to consider contemporary ARM processors and their atom counterparts as anandtech have done here. Nuvia Phoenix CPU is faster than all its ARM X86 competition ... Nuvia will continue to hold a clear position of leadership in performance-per-watt. Similarly, the Intel chip compared here is the Xeon SP 8276, which has 28 cores running at 2.2 GHz (down 18.5 percent from the Xeon SP 8280) and which costs $8,719 (down 12.9 percent from the $10,009 price of the Xeon SP 8280). As I said in my original post: hype, marketing and flat-out lies. Bet you get voted most edgy cool dood on earth! Can a True Polymorphed character gain classes? This kind of basic information that the chip makers present is just the beginning of a long process. 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. 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. Where we can find link for test for this results? There's no way to know the power consumption of stuff in AWS. And the whole point of these SPEC requirements is that the claimed results must be repeatable and reproducible by anyone. They’re overclocking their part to 3.3GHz at unknown power to eke out a 4% win (whether real or not) over its x86 rivals. So that gives that two-socket machine an estimated rating of 557 and therefore each Epyc 7742 processor a rating of 278.5. Intel, on the other hand, consumes a lot more power, to get a lot more work gone at larger form-factors. There was lot of selling off of custom ARM core designs in the marketplace over the past 6 or so years what with ThunderX2’s DNA traced back not to ThunderX1’s DNA but actually Broadcom’s Vulcan ARM core DNA. For companies that need to design their own processors, or to tweak it, this means significant savings in R&D without needing to develop everything from scratch (tricky) or to buy processors from another company (with x86, we have Via, AMD and Intel, but only intel seem really interested in the mobile space, and I have no clue what via is up to). Lots of people are blown away, by performance of M1, but are they? Tags: #20nm #28nm #arm-vs-x86 #cortex #cortex-a8 #cortex-a9 #cortex-m0 #fab #low-power #performance-per-watt #smartphone #x86. 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. And what will become of Samsung’s discontinued Mongoose development as well as AMD’s mothballed Project K12(Custom server core IP). 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. Absent that, this is nothing more than marketing in disguise. You would have a lot more credibility if you didn’t contradict yourself within two consecutive paragraphs. Are popular benchmarks valid comparisons of architectures? 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. 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. 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. Because SPEC requires a supported compiler that can be downloaded and used by anyone. This site uses Akismet to reduce spam. Going back to the data we see that the best ARM core, the custom Apple A13 Lightning is about as high performance as the best x86 core, in this case the Intel Ice Lake i7-1068NG7. 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. 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 SPEC integer benchmark result is here for a Dell PowerEdge MX740c based on a pair of these CPUs. 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. These are compared to 28-core Intel Xeon SP 8280 Platinum at 205 watts and a 64-core AMD Epyc 7742 at 225 watts. 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. They’re undercutting literally the only reason anyone would want to consider ARM: potentially lower power. 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. 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. You just have to look at the Haswell products to understand Intel is serious about power consumption in their products. The gap is so large, previous non … Take a gander: Now let’s get down to the X86 comparisons. 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. Clearly, in this benchmarketing work of fiction, none of this is true. 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. It only takes a minute to sign up. 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. Scenario 2: Apple builds an ARM CPU that’s dramatically faster than x86 CPU, both in terms of performance and power-per-watt. What is the difference between Intel (CISC) and ARM (RISC) architecture? 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.
