They probably learned a lot from microsoft’s x86 emulation and decided to go with hardware assistance. 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. It is indeed good advice to study the data and the rules behind what generated the data. 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. At 4.25GHz, the Micro Magic can accomplish the same workload as the Ryzen 4700U with less than one-third the power required. This rate is typically measured by performance on the LINPACK benchmark when trying to compare between computing systems: an example using this is the Green500 list of supercomputers. 3x higher performance per watt. It’s the same with politics. Micro Magic has provided figures—and in one case, a screenshot—for performance at 3GHz, 4.25GHz, and 5GHz. RISC-V doesn’t guarantee open implementations, that is up to implementors to decide. The simplicity of the design—RISC-V requires roughly one-tenth the opcodes that modern ARM architecture does—further simplifies manufacturing concerns, since RISC-V CPU designs can be built in shuttle runs, sharing space on a wafer with other designs. You would be better served by talking in a less technical way, and in one that emphasizes clarity. Huang 5.19GHz/1.1V.Later Ryzen 4700u SiFive Mark Santoro Lee Tavrow We're Ars 232. “World’s best CPU performance per watt”: Testing conducted by Apple in October 2020 using preproduction 13-inch MacBook Pro systems with Apple M1 chip and 16GB of RAM. The RISC-V ISA—unlike x86, ARM, and even MIPS—is open and provided under royalty-free licenses. o New Xe graphics with up to 96 execution units (EUs) with significant performance-per-watt efficiency improvements. Apple's first stab at a small form factor desktop and laptop processor offers impressive performance-per-watt metrics. I think we’re talking at cross purposes or have different goals or priorities in mind. In 2004, it was reborn under its original name by the original founders—Mark Santoro and Lee Tavrow, who originally worked at Sun and led the team that developed the 300MHz SPARC microprocessor. — 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 —. 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). I’ve been trying for so long to encourage everyone to be patient and form their opinions based on data rather than marketing claims. 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. Higher results in the chart represent better value in terms of more performance per dollar. This is all they don’t tell you. 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. 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. Micro Magic Inc.—a small digital design agency in Sunnyvale, California—has ... Home PC Apps New RISC-V CPU claims recordbreaking efficiency per watt. I’m very curious about what would happen if we started including those $1 solar powered calculators in these performance per watt comparisons. Post sell off of ARM I feel there has been an uptick in RISC-V astroturfing. If your questions are indeed about governance, you have done a bad job of explaining what you mean. https://nequalsonelifestyle.com/2020/12/06/mm-riscv-vs-rock64-arm/. CNMN Collection The AMD Embedded Ryzen V2000 family features up to eight 'Zen 2' CPU cores and seven GPU compute units, built on a 7nm process. I do agree with your comments on why the Chinese are using RISC-V and other CPUs and what they are used for. At the maximally power-efficient 3GHz clockrate, the Micro Magic CPU scores about one-fourth the CoreMarks of either the Ryzen 4700u or Apple M1. What you are talking about is implementation… I think. But there isn’t a specific standard so that peripherals all work the same, or have the same memory addresses, etc for a microcontroller. 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. Performance per watt refers to the ratio of peak CPU performance to average power consumed using select industry standard benchmarks. You need to seperate the meta issues from business decisions from implementation. I still have an Apple M1 Mac Mini on hand, as well as a Ryzen 7 4700U-powered Acer Swift 3, so those were my test systems for comparison. This is extremely crude, and I caution readers not to rely too much on comparing the M1's efficiency to the Swift 3's on these numbers alone—but it's good enough to get some perspective on Micro Magic's claim for its new RISC-V (pronounced "risk five") CPU. 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. o Power management – autonomous dynamic voltage frequency scaling in coherent fabric, 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). 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 … It's a deliberately simplified CPU benchmarking tool released by the Embedded Microprocessor Benchmark Consortium, intended to be as platform-neutral and simple to build and use as possible. At 5GHz, it outruns all four of the SiFive's cores. 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. 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. Unsurprisingly, both parts produced more performance per watt when exercised with one work thread for each available CPU thread. In that SolarPV sector it’s more about heat management and durability when exposed to UV. Literally, it measures the rate of computation that can be delivered by a computer for every watt of power consumed. PC Apps; New RISC-V CPU claims recordbreaking efficiency per watt. Oops. Micro Magic's new CPU prototype is seen here running on an Odroid board. I’d really like to see RISC become the platform of choice for FOSS, but we’ve got a bit of a catch-22: we need manufacturers to make these products viable, yet all too often when they do it comes will strings attached, proprietary blobs, and owner restrictions. Corey Gaskin - Nov 10, 2020 6:38 pm UTC If you've got access to a Linux system, it's pretty easy to download, compile, and run CoreMark yourself. I hear what you are saying, but I think you are looking for RISC-V to be more than it is, and that it wants to be. Anyways if you want to end the discussion here that’s ok! It’s surprisingly difficult to convince people to detach themselves from preconceived opinions and look at the data sometimes. o New Willow Cove CPU core with significant frequency uplift leveraging 10nm SuperFin technology advancements. At the power-efficient 3GHz clockrate, the Micro Magic CPU is nearly three times faster than, for example, SiFive's Freedom U540 CPU running single-threaded. For some or all of this to work via a fastpath or slowpath (could be hardware or software) the overall concepts and systems and regulations which enable this need to be worked out and specified. With that said, it's worth pointing out that—if we take Micro Magic's numbers for granted—they're already beating the performance of some solid mobile phone CPUs. Core performance with Nuvia’s Phoenix. At it’s high end it’s as capable as those processors so it would have a decent use case in the same space as what you’d use Pi’s or Rock64 boards on. Can they scale to more demanding uses? We're also still taking a pretty fair amount of Micro Magic's claims at face value. Yield per watt is one of the elements that marketers commonly use to promote their products as a performance metric. A lot was identical differing only in implementation where implementations certified for industrial use took less shortcuts and were pixel accurate, and retail implementations were a bit quick and dirty in places and sacrificed accuracy for performance reasons. None of this made much of a dent in the Micro Magic's commanding lead in power efficiency. However somebody obviously does have to care about this stuff and many of us here on osnews do find these things important. That is is. Switzerland recently had its own scandal when it turned out one Swiss supplier of backdoored security products was owned by US and German intelligence. 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. 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. Reading through wiki I note RISC-V have incorporated themselves in Switzerland to avoid the issue of unilateral sanctions. You must login or create an account to comment. 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. The material on this site may not be reproduced, distributed, transmitted, cached or otherwise used, except with the prior written permission of Condé Nast. With modern backend cloud implementations being available in the PS5 for some cases the fastpath will be over an external network.). They add one or more layers of printed SolarPV to conventional PV to boost performance. Micro Magic was originally founded in 1995 and was purchased by Juniper Networks for $260 million. 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 . Because RISC-V doesn’t dictate the implementation, extra instructions for emulation aren’t guaranteed to matter. In computing, performance per watt is a measure of the energy efficiency of a particular computer architecture or computer hardware. The world’s fastest CPU core in low-power silicon; The best CPU performance per watt of any computer chip ; The world’s fastest integrated graphics in a personal computer; Breakthrough machine learning performance with the Apple Neural Engine; The M1 chip is available in the new MacBook Air, 13-inch MacBook Pro, and Mac mini. RISC-V endorsed the Wishbone bus for systems on a chip but vendors aren’t required to use it. So calling conventions, etc aren’t defined. At this point I’d be happy if someone with influence produce a discussion document covering things like acces to instruction sets, interoperability with things like transcoding, the OS and VM layers, support for end users investments in software, the use of escrow and barriers such as copy protection and copyright. I have some major reservations about all of these claims, mostly because of the lack of benchmarks that more accurately track real-world usage. Later the same week, Micro Magic announced the same CPU could produce over 8,000 CoreMarks at 3GHz while consuming only 69mW of power. For people with use case and power envelopes which match the capabilities either would be useful if Arstechnica tests are accurate. One AMD Ryzen Embedded V2000 Series processor can provide twice the multi-threaded performance-per-watt, up to 30 percent better single-thread CPU performance and up to 40 percent better graphics performance over the previous generation. Ad Choices. However it provides implementors a common, modular, and extensible ISA that is unencumbered by patents or other IP concerns. We would do the same if we were in their shoes. Here is the thing, you keep asking low level questions (or ones that can only be answered in a low level way because of what RISC-V actually is), and then get seemingly upset when we answer that way. For example: 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. Performance per watt refers to the ratio of peak CPU performance to average power consumed using select industry standard benchmarks. Now that we understood all that, the next step in order to better evaluate Micro Magic's claims was to run a few CoreMark benchmarks of our own. Join the Ars Orbital Transmission mailing list to get weekly updates delivered to your inbox. For the vast majority of use cases there’s no real need to step away from. But isn’t it OK for those to be a subset of the whole, so consumers can choose, and still know that code will run on those processors transparently as proprietary implementations? 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. 17. There is flexibility but this contains gotchas. And you can find that at the RISC-V website, I won’t google that for you. 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). Implementations are left to implementors. 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. For the M1, apple chose to implement x86 memory model in hardware rather than in software to avoid certain implied inefficiencies of software overhead. Then we had the Fahrenheit scandal where Microsoft punked SGI and then went on to use their monopoly to force Direct3D on the world as well as use their position to push into console gaming and the cloud (while not releasing OS which gave basic users and businesses the capability to host their own local cloud). 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). “World’s best CPU performance per watt”: Testing conducted by Apple in October 2020 using preproduction 13-inch MacBook Pro systems with Apple M1 chip and 16GB of RAM.
