I see the administrator has now added a performance per dollar section. In the example case of the Intel Core i7-7820EQ, when CWR is applied with 94% performance preservation, the CPU power can be reduced to as low as 56% while the Performance-per-Watt is increased to 1.71 times higher. This is why I asked you to define what you meant, and ended up making a guess. Part 1, [Updated with response from Apple] Macs are a privacy nightmare, Working from home at 25MHz: You could do worse than a Quadra 700. Some scepticism and expertise is required and not everyone has the training or time or inclination for this. An open and competitive architecture won’t happen unless there is this involvement. I agree we are unlikely to see any movement on this although there are plenty of technical people who are interested. 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 . I always thought OpenGL got a lot of things right. Extraordinary claims requite extraordinary evidence, and I feel like some vague photos just doesn’t to the trick of convincing me. RISC-V doesn’t guarantee open implementations, that is up to implementors to decide. There was a universal core you could depend on with everything else being an extention. So am I, but times change. The politics is a bit of an issue I agree although the law is a lot clearer so easily subject to technical discussion and there is a fair degree of case law and science to lean on. 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. 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? So I can see this chip stuff in the lower power market becoming very dominant, provided the applications can keep the processors cool. We kijken dan naar het verbruik tijdens diverse workloads, maar dat vertelt niet per se het volledige verhaal over hoe zuinig een cpu is. 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). They probably learned a lot from microsoft’s x86 emulation and decided to go with hardware assistance. CPUs play a key role in determining overall performance in balanced system s, but also account for more than half the power those systems consume. An individual Edge TPU is capable of performing 4 trillion operations (tera-operations) per second (TOPS), using 0.5 watts for each TOPS (2 TOPS per watt). Then again, last time I said anything about an upcoming processor, I was off by a million miles, so what do I know? While Apple claims the octa-core M1 delivers “the world’s best CPU performance per Watt,” the M1 breaks down to less than 100 CoreMarks per Watt, claims Huang, an industry notable who designed the Finesim simulator. I do agree with your comments on why the Chinese are using RISC-V and other CPUs and what they are used for. 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. Dell Active Power Control (or DAPC), relies on a BIOS-centric power control mechanism which offers excellent power efficiency advantages with minimal performance impact in most environments , and is the CPU Power Management choice for this overall … 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’m sure someone will find a use. Does anyone have any ideas what? The industry then broke down into industrial use versus game use. For example: 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. Small world. 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. Sorry but I don’t get what you are saying. performance per watt. It will be interesting to see how AMD will react to Intel's next-generation processors. Woodcrest will give the server market more than 3 times the performance per watt of Intel's Nocona which debuted in 2004 and Merom will mean a 3x performance per watt boost for the mobile market since Intel presented the first Pentium M Banias in 2003. New RISC-V CPU claims recordbreaking performance per watt, https://www.nextplatform.com/2020/08/21/alibaba-on-the-bleeding-edge-of-risc-v-with-xt910/, https://nequalsonelifestyle.com/2020/12/06/mm-riscv-vs-rock64-arm/, Review: Dell Inspiron 6400 Core 2 Duo Laptop, Dueling Multicores: Intel and AMD Fight For the Future. When I say modular I mean that if you don’t want floating point, you can leave out that module, etc. It’s the same with politics. The 'SYSmark Performance per Watt' can be misleading when comparing the dual and quad core processors, particularly when looking at other types of loads that make better use of the additional cores.

I would hate to think how much inaccurate information we would get we we started asking user's how many watts their GPU & CPU … What the Chinese are up to at a hardware level is a response but I’m fearing the Chinese are basically taking an open system and (like NVidia who are ten times worse than AMD/ATI ever were) are effectively closing it in practice. 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). A lot of people only want to focus on the benmarks where it does well and ignore those where it is behind. 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. Elke watt kost je per jaar €1,30 aan energie, dus dat kost je per jaar meer dan 30 euro extra. 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. Exactly! 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. You say that you don’t care about implementation, which is fair enough given that many users don’t care either. Later the same week, Micro Magic announced the same CPU could produce over 8,000 CoreMarks at 3GHz while consuming only 69mW of power. So to summarize, there is binary compatibility so long as bitness and ISA subsets match, but that doesn’t doesn’t mean that you can just move from one CPU to another and assume that IO and the like all work the same. In onze tests van processors is het energieverbruik een vast onderdeel. To borrow from (classic) OpenGL again you have core functionality which is good enough for everyday use. The x86 memory model is more strict and emulating it in software is inefficient. It's because they've invested so much in performance per watt that they can be in all markets with ease and not having to waste time and money on new masks and semi-custom product research. Given time (and this is still very new) you probably will see chip manufacturers who are as open as they can possibly be, hell we may see completely open fabs at some point. An NVIDIA Max-Q GPU is the same as a desktop one, it's simply just tuned to a different performance/power profile. The Ice Lake and Zen 2 … I lament that this did not happen with ARM and for better or worse this leaves x86 (with all of it’s problems) as the friendliest FOSS platform to date. GCC and LLVM collaborated on what they wanted from a compiler implementation level, but anyone is fine to define their own (as with any other CPU). It’s surprisingly difficult to convince people to detach themselves from preconceived opinions and look at the data sometimes. 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. I was just adding my own opinion. 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. You would be better served by talking in a less technical way, and in one that emphasizes clarity.

I’ve been involved on a bit of this stuff for the printed SolarPV, in that sector the target is $1/m² but the cost of what you can do in that square meter doesn’t rise proportionally with the density of devices on the film. AMD has launched the next-gen lineup of its Embedded processors in the form of the V2000 chips. I’m very curious about what would happen if we started including those $1 solar powered calculators in these performance per watt comparisons. 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. . With both M1 and this there is a reason for healthy skepticism, even if the results ultimately prove out in the end. For people with use case and power envelopes which match the capabilities either would be useful if Arstechnica tests are accurate.

Ars Technica summarises and looks at the various claims made by Micro Magic about their RISC-V core. Tags: None. Oops. However somebody obviously does have to care about this stuff and many of us here on osnews do find these things important. I would choose something as Haswell Refresh or Skylake. I think you have to just look at the spec or trust me when I say the core spec defines a thoroughly modern CPU with feature sets on par with any modern CPU, I also think you need to define what you mean by transcoding, because it feels alien to my understanding of the term, After a lot of thought I suspect by transcoding you mean additional instructions to facilitate emulating other architectures (for example x64) vit a JIT or AOT compiler, and yes there is working group J that is looking into that, however that may not be the right approach. 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. What would also be good is a performance per watt section too. If your questions are indeed about governance, you have done a bad job of explaining what you mean. For a long time, the equation 'clock speed = performance' was an accepted measure of real-world performance or in other words for value. Post sell off of ARM I feel there has been an uptick in RISC-V astroturfing. 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. 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. Because RISC-V doesn’t dictate the implementation, extra instructions for emulation aren’t guaranteed to matter. Ultimately, while I have good vibes from RISC-V, I still fear that its openness could be subverted by corporate influences like has happened with most of our ARM devices. What you are talking about is implementation… I think. AMD’s Ryzen 7 3700X is a generational CPU update that’s worth ... octa-core processor reached just 148 watts under load in ... demolishes its predecessor in performance per watt.
