Qualcomm says the Snapdragon 888 boasts three times more performance per watt over the previous generation, as well as 26 tera operations per second (TOPS). New RISC-V CPU claims recordbreaking performance per watt Thom Holwerda 2020-12-04 Hardware 26 Comments Ars Technica summarises and looks at the various claims made by Micro Magic about their RISC-V core. On the Ryzen-powered Linux system, I used the utility turbostat to get both Core and Package power readings while the tests were running. Huang demonstrated the CPU—running on an Odroid board—to EE Times at 4.327GHz/0.8V and 5.19GHz/1.1V. In computing, performance per watt is a measure of the energy efficiency of a particular computer architecture or computer hardware. Marketing especially unethical marketing by its nature is not about communication and persuasion on the merits but about subverting your judgement. Yield per watt is one of the elements that marketers commonly use to promote their products as a performance metric. ... offers big improvements in performance per watt … Apple specifically needed backwards compatibility in order to run their customer’s proprietary mac software, but not everyone is as tied down to x86 software compatibility. For a broader context there are software versus fastpath issues where a given OpenGL function may have been fully or only partially implemented in typically faster graphics card hardware . Jim Salter - Dec 4, 2020 11:15 am UTC. I benchmarked it against the PineBook Pro. There is also the open source Hummingbird processors that are aiming at the Cortex-M space. I’m a bit sceptical of RISC-V as it seems more of an American thing and wonder if pushing RISC-V is less about technical and equity issues and more about who ultimately controls and influences the CPU platform. Ars Technica - Jim Salter ... 10 Calming Gifts for People With 2020 Anxiety Mashable. The Snapdragon 820 isn't world-class anymore, but it's no slouch, either—it was the processor in the US version of Samsung's Galaxy S7. o New Willow Cove CPU core with significant frequency uplift leveraging 10nm SuperFin technology advancements. Read our affiliate link policy. All rights reserved. Sign up or login to join the discussions! If we use the EMBC's published single-core score for the Snapdragon 820 along with Anandtech's single-core CPU power test result, we get about 16,000 CoreMarks per watt. You’ve explained some of the detailed issues which helps but there’s two issues here. To put that in perspective, last year’s Snapdragon 865 with the 5th gen AI Engine featured 15 … Performance per watt refers to the ratio of peak CPU performance to average power consumed using select industry standard benchmarks. https://www.nextplatform.com/2020/08/21/alibaba-on-the-bleeding-edge-of-risc-v-with-xt910/. The 5nm M1 system-on-a-chip (SoC) features an 8-core CPU, which the company claims delivers the best performance-per-watt of any processor on the market, and up to … Ad Choices. Ars may earn compensation on sales from links on this site. Your California Privacy Rights | Do Not Sell My Personal Information When we look back at the single‑threaded performance of low‑power silicon in the Mac, gains in performance per watt have been very small from one chip to the next. I was just adding my own opinion. You say that you don’t care about implementation, which is fair enough given that many users don’t care either. That is is. Micro Magic's new CPU prototype is seen right here working on an Odroid board. The lesson of Apple’s M1 is that you don’t need new instructions (to the best of our knowlege there are no additional instructions in the M1 for that), but a different Mode to implement the intel consistency model so the code would execute more like an x64 processor. This means that a RISC-V CPU can be anything from a microcontroller to a server grade CPU, and doesn’t have to implement the modules it doesn’t need. There was a universal core you could depend on with everything else being an extention. 2020 is the year of a global pandemic that forced many of us to work from home. CNMN Collection I am not saying anything about politics, but their policy of favoring home grown processors internally is creating great incentive to be competative. None of this made much of a dent in the Micro Magic's commanding lead in power efficiency. I don’t know enough about the engineering to know what is covered by patent versus trade secret to know how much or little they can open up and this is before international security and trade wars are considered. I’m not getting into whataboutary or having words put in my mouth and as I think we’ve covered everything this is probably a good place to end discussion. Jim Salter Andy Huang 200mW. . Unsurprisingly, both parts produced more performance per watt when exercised with one work thread for each available CPU thread. WIRED Media Group Later the same week, Micro Magic announced the same CPU could produce over 8,000 CoreMarks at 3GHz while consuming only 69mW of power. I tested the Apple and AMD CPUs both single-threaded and multithreaded when checking power efficiency. The Embedded Microprocessor Benchmark Consortium (EMBC) is a group with wide industry representation: Intel, Texas Instruments, ARM, Realtek, and Nokia are a few of its more notable and easily recognizable members. So calling conventions, etc aren’t defined. Getting the raw performance scores was considerably easier than getting truly comparable power readings. o New Xe graphics with up to 96 execution units (EUs) with significant performance-per-watt efficiency improvements. At 3GHz, that figure plummets to less than one-eighth the power required. So I can see this chip stuff in the lower power market becoming very dominant, provided the applications can keep the processors cool. However it provides implementors a common, modular, and extensible ISA that is unencumbered by patents or other IP concerns. That's triple the efficiency of the Ryzen 4700u running single-threaded and a little better than par with it when the Ryzen's running an optimally multithreaded workload. Later the same week, Micro Magic announced the same CPU could produce over 8,000 CoreMarks at 3GHz while consuming only 69mW of power. Scenario 1: Apple builds an ARM CPU just as fast as an x86 CPU, and is able to leverage its own ecosystem to deliver a modest improvement in performance per watt… Apple's first stab at a small form factor desktop and laptop processor offers impressive performance-per-watt metrics. For the Apple, I only had access to whole-system power draw, so I subtracted the "desktop idle" power draw from the "under test" power draw. Today, Micro Magic announced another breakthrough, promising “the world’s highest performance/power 64-bit RISC-V core at 110,000 CoreMarks/Watt.” The Micro Magic RISC-V processor used in today’s 3GHz demo appears to be essentially the same as the similarly unnamed core in the EETimes demo running at 5GHz and 13,000 CoreMarks at 1.1V. I’m a bit sceptical of RISC-V as it seems more of an American thing, Oh china is biting pretty hard on RISC-V as well. Even aside from hardware considerations like GPU and LTE modem, creating an entire Android phone based on a non-ARM architecture is likely to be a much bigger undertaking. Not only does the new design appear to perform well while massively breaking efficiency records, it's doing so with a far more ideologically open design than its competitors. 17. But when we factor in power efficiency, things get crazy. Micro Magic was originally founded in 1995 and was purchased by Juniper Networks for $260 million. We first noticed Micro Magic's claims earlier this week, when EE Times reported on the company's new prototype CPU, which appears to be the fastest RISC-V CPU in the world. This specifically avoids most effects of system differences in memory, I/O, and so forth. I’m old enough to remember scenes on the news of Chinese wearing Mao suits and going everywhere on bicycle. I think we’re talking at cross purposes or have different goals or priorities in mind. Even at its efficiency-first 3GHz clockrate, the Micro Magic CPU outperformed a Qualcomm Snapdragon 820. Once you get to the FAB you are so caught up in proprietary processes you simply can’t be as open as you want (If I am reading you correctly), and if there were more restrictions placed on it then you wouldn’t see as many private companies adopting RISC-V so quickly (for example Western Digital). Implementations are potentially going to vary within a single semiconductor company, and this is what we want. The numbers support that and do show ARM is more efficient in doing the tasks at hand, in this case Geekbench 5. If your questions are indeed about governance, you have done a bad job of explaining what you mean. I expect government regulators would have an eye on this too if public discussion got enough traction. I gave my Ryzen and Apple processors the benefit of every possible doubt when generating the above charts—I used core power (not total package power) on the Ryzen 4700U and ran tests with the Gnome3 desktop shut down. Two charts below (currently on-sale and all-time value) displays the top Videocards in terms of value. You need to seperate the meta issues from business decisions from implementation. Micro Magic adviser Andy Huang claimed the CPU could produce 13,000 CoreMarks (more on that later) at 5GHz and 1.1V while also putting out 11,000 CoreMarks at 4.25GHz—the latter all while consuming only 200mW. I don’t know really being only casually familiar with it. Everyone has their opinions and musings. AMD claims that in comparison to Intel’s Core i7-1065G7 processor, the Ryzen Mobile 4000 Series will be able to deliver up to a 30% increase in graphics performance. In addition to building the operating system itself—not just the kernel, but drivers for all hardware from GPU to Wi-Fi to LTE modem, and more—third-party app developers would need to recompile their own applications for the new architecture as well. Putting words in your mouth, huh? There are completely open and inspectable implementations of RISC-V that I think satisfy what you want, but at it’s core RISC-V is intended to spur innovation, research, implementations, etc by providing a common, IP-Free ISA. Jim Salter Seeed studios sells various versions of them (and a rather cheap FPGA board if you want to experiment yourself). All we needed to do here was clone its GitHub repository, then issue a make command—optionally, with arguments XCFLAGS="-DMULTITHREAD=8 -DUSE_FORK=1" if we want to test on multiple threads/cores at once. Micro Magic Inc.—a small digital design agency in Sunnyvale, California—has ... Home PC Apps New RISC-V CPU claims recordbreaking efficiency per watt. This concerns me a great deal because while x86 has kind of been grandfathered in as a platform where FOSS can thrive, for most new devices coming out we aren’t so fortunate and very often we’re forced to hack into our own devices for the right to run independent software. The nitty gritty of transcoding and subsystems (and VMs) cooperating with each other to anyone can run anything they like without vendor lock-in and forced obsolescence is a technical thing. While we've seen a screenshot of an 8,200 CoreMark score, and we've seen a 69mW power reading, it's not entirely clear that the power reading was representative of the entire benchmark run. There is flexibility but this contains gotchas. People often take such things for granted, but if too few people take an active role to ensure open platforms remain viable, they can become marginalized and become niche/”second class citizens” in the real world. As for whether it is good for all things all the time we don’t really know so comparing them to currents major CPUs isn’t an exact comparison. — AMD Ryzen Embedded V2000 Series processors deliver double the cores 1, up to 2x the performance-per-watt 2 and an estimated 15 percent IPC uplift 3 over the previous generation —. Huang demonstrated the CPU—running on an Odroid board—to EE Times at 4.327GHz/0.8V and 5.19GHz/1.1V. At an abstract level I don’t really care whether transcoding is done via hardware or software (ditto support for VMs and hooks or subsystem mechanisms for different OS to run at the same time). So am I, but times change. The Linux operating system already supports RISC-V architecture—so for headless or near-headless controllers that simply need to deliver decent performance paired with extreme power efficiency, Micro Magic's new CPU is likely most of the way there. Included in these lists are CPUs designed for servers and workstations (such as Intel Xeon and AMD EPYC/Opteron processors), desktop CPUs … 232. But is ... What is performance per watt? With their projections for the Phoenix ARM core, Nuvia is claiming a performance per Watt advantage over the current core offerings from Apple, Qualcomm, Intel, and AMD. For the vast majority of use cases there’s no real need to step away from. Lobbyists and vested interests with deep pockets and now too many politicians spend more time leaning on marketing than creating good legal frameworks and policy based on the public interest. When I say modular I mean that if you don’t want floating point, you can leave out that module, etc. In addition vendors are allowed to create their own modules to push functionality down to the processor level (for example this is what WD is doing). 3x higher performance per watt. Reading through wiki I note RISC-V have incorporated themselves in Switzerland to avoid the issue of unilateral sanctions. I’m just happy being able to broach the subject. Exactly! Implementations are left to implementors. Micro Magic's RISC-V CPU delivers about 1/4 of the raw performance of a single Apple M1 Firestorm core at its hyper-efficient 3GHz clockrate. November 30, 2020. gokul nath. ... promising that the M1 will offer the world's best CPU performance per watt. (In some cases CPU was actually faster than the hardware renderer due to the technology of the time. The Micro Magic CPU is, for the moment, single-core and single-threaded—although Huang says it could "easily" be built as a 25-core part. And you can find that at the RISC-V website, I won’t google that for you. New RISC-V CPU Claims Recordbreaking Performance Per Watt 1 min read December 4, 2020 Hmmmmmm shares a report from Ars Technica: Micro Magic Inc. — a small electronic design firm in Sunnyvale, California — has produced a prototype CPU that is several times more efficient than world-leading competitors, while retaining reasonable raw performance . The Snapdragon 888 also offers more energy efficient than the Snapdragon 865, with a 25% improvement in the CPU's performance-per-watt and 20% more … By Paul Alcorn 27 November 2020. So so long as the bitness, and subsets match, binary executables will carry over and run the same, and this is what you (or at least I) would want. Sorry but I don’t get what you are saying. RISC-V endorsed the Wishbone bus for systems on a chip but vendors aren’t required to use it. This can be annoying when you try to have an objective conversation, but that is human nature I suppose, haha. This is the level I’m kind of discussing. RISC-V is one of the ways they are doing that, along with RISC-V, MIPS, ARM, and x86. Well you can see some of that discussed in the FAQ, and you can get into the weeds by looking at the implementer’s guide. This is the point where I think engineers need other people who understand the governance and consumer rights issues to step in and add support otherwise engineers are always going to be at the mercy of the boss class and financiers. We need to give implementers the freedom to experiment and innovate, and RISC-V gives them a compatible ISA to do that. SANTA CLARA, Calif., Nov. 10, 2020 (GLOBE NEWSWIRE) -- AMD (NASDAQ: AMD) today launched a new product in its high-performance Embedded processor family, the AMD Ryzen™ Embedded V2000 Series processor. https://nequalsonelifestyle.com/2020/12/06/mm-riscv-vs-rock64-arm/. Still, this is an exciting development. I don't have access to anything nearly as fine-grained as turbostat for the Apple M1, so for that platform I took whole-system power draw at the wall and just plain subtracted the reading at desktop idle from the sustained reading while under test. By. ... impressive performance-per-watt metrics. I think this really needs a technical vision articulating examining what is and isn’t possible then a deeper look at the gotchas and whether vendors will cooperate or not, and the use and abuse of patents and copyright to stop an advance in this area. Fair comment. Because RISC-V doesn’t dictate the implementation, extra instructions for emulation aren’t guaranteed to matter.
