x86 or x86-64 is the name of the architecture used by Intel and AMD to make their processors. RISC-V is a relatively new architecture that, besides being RISC rather than CISC, is free to use without a license. Intel is strengthening its commitment to RISC-V, so what is the difference between RISC-V and x86? Let's find out.

At Intel, they pronounced the 8080 and 8086 as “eighty eighty” and “eighty eighty-six.” Similarly, the 80386 and 80486 was pronounced as “eighty three eighty-six” and “eighty four eighty-six.”

Minor correction, the 80286 didn't have an MMU in the classic sense. It's protected mode used segmentation to expand the memory space. You could also use the "present" bit to swamp segments to disk - although I'm not aware of an OS that did it.

So it's more like an API specification. Like C99 is an open standard implemented by different compilers and standard libraries, some of them proprietary.

So from what I'm seeing here, RISC-V will end up dominating the microcontroller/embedded market first. I read a few presentation slides from some of the companies sponsoring RISC-V, and some of the reasons listed is not just because it's free- but because it's also well-designed, and without obligations to legacy design decisions. Because of this, it can even overtake MIPS and PowerPC despite both of these being free as well. RISC-V cores might not be that advanced right now, but since literally anybody could come along and make one, I can see some designs catching up quickly. AMD and Intel could use some of their own non-x86 specific IP for RISC-V. 3D cache could be used for anything, same with other manufacturing processes. Organizational talent determines a lot. If Nvidia manages to successfully buy ARM, a lot of companies will be unhappy enough to start switching to RISC-V for those particular needs. And if that's the case, why bother with either MIPS or PowerPC?

risc is more efficient, but until risc can be designed to be a brute it wont get into the actual pc market and will stay in phones, iot, routers etc. Apple did do the M1 and it IS impressive, but its still not quite there. It would be cool if arm became a removeable socket design, but the other issue is Windows and ISA's. Pretty much x86 owns Windows and the world uses Windows so theres that.

Your claim that "RISC CPU performance is generations behind x86" needs clarification - in an equal benchmark condition(clock freq, OS family, app task), all RISC CPUs perform much better than x86. The simple reason behind this is the x86 needs to run many microcodes (similar to RISC instruction) for every x86 instructions. In addition, compilers can generates much more optimized code for RISCs than x86. Late 1990s, x86's life time wasn't positive as so many RISCs were beating x86 - performance. That time, however, the CPUs were clocked at most 100MHz, where x86 cannot compete RISC for any non-floating point benchmarks. Just before the dotcom bubble, the silicon started its evolution to speex the clock - when x86 is clocked few hundreds MHz, not much performance diff with RISC. And so those many high performing RISCs suddenly lost their monentum as there were so many x86 apps (even x86 Linux was the most stable) waiting for better performing x86. Most CPU people would agree that x86 ISA is a stone age artifact that should have been gone years ago but still much alive and strong - simply because of this SW compatibility. Nowadays RISC V became highlighred because there're apps require more CPU power than fastest x86 - I think RISC may resurrect to help those power hungry apps.

Risv-V was launched as a direct competitor to the ARM business model, with all manufacturers allowed on board.. It quickly became part of the US global-corp CPU & GPU CABAL... Now The Cabal owns ARM and soon Risc-V outright.. Sooooooo New World Order.. It's a bloated, all-encompassing standard that's now a variable length instruction set, CISC on RISC architecture.. Standards kill competition when in the hands of uber-corp CABALS.
PrivateSi

@Gary Explains .. Remember what X86 did to the CPU market... killed all our old favourite competition companies and CPU architectures, and the variety of home computers.. The only good thing was standard peripheral interfaces, that I am all for, including STANDARD CPU SOCKETS!... I very much doubt Risc-V players will do that, unless they merge, which is not possible under current monopoly laws - but Globalist NWO types are in control so who knows... but anyhow, they have their CABAL so no problemo!
PrivateSi
PrivateSi 2 місяці тому
@Gary Explains .. Same with all open standards, but competition to implement the standards kicks in, killing off the more independent, innovative competition in the long run... Standards in the hands of industry cabals accelerate this process.. The idea of Risc-V is to replace X86, X64, all ARM architectures, and MIPS, PICs/ Arduinos... -- Competition will increase for a bit, but The Cabal remains in total control and compete on their terms at the top. They all be racing to offer compatible modular design solutions so Risc-V will kill others that do the same in their own modular ecosystem. As an ARM fan I kind of give up.. It was bad enough when The Globalistas got most of them, shares-wise, now nVidia have them, I weep, as an Englishman!.
Gary Explains
Gary Explains 2 місяці тому
But I thought all those extensions where optional, which means if a CPU designer doesn't think they had value in terms of performance or cost too much in terms of silicon or energy, then they don't need to be used. You don't like the "overreaching" stuff, then don't use it. Is that the whole point?
PrivateSi
PrivateSi 2 місяці тому
@Gary Explains .. Hi Gary.... Overreach, in a word.. Every year The Standard encompasses more and more instructions across more markets.. The Big Boys getting together to stop ARM, originally... The instruction set now allows 2,4,6,8 byte instructions, and beyond...Suppresses incompatible innovation.. nVidia could kill ARM if Risc-V takes over.. Too many cooks compromising and adding extra stuff to the broth... You have to admit, it's now more cabal than 'open standards group'.. -- Sensible innovations such as the removal of all immediate values for truly fixed length instruction sets are not possible. 'Register Windows' into a precached list of method constants stored before the method start save much space and enable fully fixed length instruction sets.. Long jumps can use an 8 byte index to constants stored in another list before the method start. This also helps the branch predictor... -- Using Indexed, Precached Method Constants + other techniques enables 2 byte instruction sets to match the feature set of X64 up to AVX256, including all SSE, AES etc. - with a lot of room to spare.. You'd be amazed what a truly REDUCED INSTRUCTION SET can do, CISC-on-RISC-wise..

@Gary Explains - Maybe you're right. I could have overestimated the ability of other companies to copy what Apple has done, though it definitely helps to have something concrete to emulate. No, I didn't know Samsung had stopped making chips. I guess we'll see what happens. Either way, thanks for taking the time, Gary. You're probably right.
Gary Explains
Gary Explains 2 місяці тому
Thanks for your reply. BUT... BUT... The broader concepts are understood, but Apple's processors are still faster! Why? Because there is more than just the broader concepts needed to build a high performance CPU. If it was just broad concepts that everyone would be making CPUs. Did you forget that Samsung recently closed it custom CPU division because it COULDN'T build a good enough CPU. Sorry "board concepts" isn't enough. Again you mention Apple's processor in the iPad, but as I pointed out, ONLY Apple is doing that. If it was easy, everyone would be doing it. But it is hard. Also I think you are overestimating the intrinsic benefits of RISC. RISC has been around for decades and until now it always lost. If it was intrinsic then RISC would have dominated from the beginning, it didn't.

You used to have to pick between a core with high performance and terrible efficiency, or a core with excellent efficiency that ran like honey. Now, modulo discrete graphics, we can have i9 performance with iPad efficiency. Eliminating that compromise is predicated on properties that are intrinsic to RISC computing. If the industry ever wanted RISC-V, it wants it now.
Carl Younger
Carl Younger 2 місяці тому
@Gary Explains - The broader concepts are well understood. Unified memory has been done before. The stuff with pipelines and caches generally applies to any RISC architecture, and the way Apple bakes "helper cores" into its chips is also something other companies can copy (the industry knows how to do decryption, video decoding etc in hardware). I expect Samsung, Microsoft, Google etc are looking to achieve comparable things with their ARM designs over the next few years, which will accelerate advancement of RISC computing generally (CISC architectures cannot do the stuff the M1 does).

Gary, Can I please ask you to explain something to clear my confusion?! Windows 11 just announced that it will only run on 64bit CPU’s (I think this just means the OS will only be 64-bit?) but still supports 32 bit applications. While I understand that Intel CPU’s still have 16/32/64 bit ISA support - for pure ARM64 CPU’s is it possible to run 32-bit applications (or is it emulated somehow?) I guess the M1 can support emulation x86 (32bit) and x64 (64bit) apps - can’t it?

But it does parallel Linux in that it is proving to be a natural fit for solving big business needs. When we say RISC-V is a "Linux-like revolution" we're not really talking about the hobbyist markets, we're talking about how rapidly and completely the big business leaders in hardware are adopting this open standard and contributing to its continued development. Linux may have started off as a hobbyist exercise and, because its software, development is more accessible to home devs, but it is business need that truly drives GNU/Linux's popularity to this day. In this way it is quite like watching Linux take over the industry, and reminds me, personally, of Linux's rise to prominence.

Nice. An interesting feature is the vector nature in opposition to SIMD (à la old Cray vector supercomputer). Anyway, the only video that clarifies a common misconception of this ISA, which many think that is an open source one, but actually an open base ISA specification which does not imply necessarily an open source implementation. In fact most extensions which gravitates around this ISA are closed source, namely DSPs, some MCUs, etc.

As I said in the video, one instruction per cycle is no longer the aim. Modem Arm Cortex-A processors have high levels of ILP and it is nothing to do with instruction fusion, it is because they have wide pipes with multiple backend units for ALU, Load/Store, etc.

CPU architectures alternative to x86 just don't sit well within Intel's businesses. Intel owned many other alternative chip architectures before, like iAPX 432 (i860, i960) and Itanium. They all died horrible deaths while x86 always stays Intel's favorite. The cost of a few billions to buy Sifive is simply nothing to Intel either. Once Intel owns Sifive and all its IPs, RISC-V is going to die too.

@Gary Explains I missed out Intel's XScale architecture which is also no more. As for why a non-x86 architecture like RISC-V would die under Intel .... maybe because many Intel CEOs would like to have their own business strategy and it only takes one who likes to consolidate Intel core CPU business and the alternative non-x86 architecture will disappear faster than you can say x86.

@Gary Explains This is the best data we have on performance at the present time. I am sure zero data on A versus zero data on B means a lot to somebody, like the art community. Also if A > B and B > C, we know A > C, so you can compare x86, ARM and Risc-V. In addition a lot of problems in the technical world have to be solved by interpolation, extrapolation and educated guessing. I was one of the designers of DDR3 sodimms. We had to do the signals and power delivery. The signals were easy to simulate. The power delivery was pure guess work, because we did not have access to a model of on die power delivery, for the Sdrams. Now that Intel has a technical person in charge again, I am sure they are making decisions based on numbers. If I was still working at Intel, I am sure I would have seen a technical presentation comparing all three technologies and their future. Intel might even have an ARM versus Risc-V presentation on their website soon. Lastly, with China going all in on Risc-V, I doubt we will be talking about x86 in five years. Also since the future is A.I. with machine learning, maybe this whole conversation is about horse and buggy technology.

Ridiculous. No, RISC-V is _not_ free to use. Only the basic instruction set is free, which is not something you could manufacture. Anything more than that, you have to pay, not a single penny less than ARM. By the way, a free open source CPU does exist, it's called "Open RISC", it has been there over a decade. RISC-V is a scam.

New chip fab technologies will be developed, making chip fab more efficient, less expensive, and therefore more accessible. That means more people making chips based on RISC-V implementations, which means faster innovation. I think X86 will be replaced by some future custom RISC-V implementation, but not necessarily from a company equivalent in size to Intel. Public entities can get in the mix, also, because RISC-V is open standard. Some governments do have a lot of money to put toward chip development, if they are so inclined (which it appears some are, for the sake of their own national security and economic independence). We should want as many people as possible developing new chip technology. Innovation is stifled when a few ultra large corporations control the pace of development.

Thank you Gary, you are right Arm is the biggest threat to the Intel/AMD x86 processors, so in the end the battle between RISC and CISC continues and I think Arm will eventually replace significant part of the market previously dominated by the Intel and AMD. For example in the enterprise market with the business critical servers x86 processors took the baton from the custom design processors like Itanium and its doing quite well. I also agree that if Nvidia succeeds to buy Arm both x86 giants Intel and AMD would need work very hard to keep and even harder to expand their market share as expectations to grow Arm in the future are quite obvious. Maybe you can make another video about what if Nvidia buys Arm, what it would mean for the market and for the future? ;)

This is brilliant marketing, because the "7nm process" is a commercial term and does not represent any geometry of the transistor. ( en.wikichip.org/wiki/7_nm_lithography_process or en.wikichip.org/wiki/5_nm_lithography_process ). This change from physical structures on the chip to a purely marketing term happened in the 90's, before then a "XXX nm node" typically described the gate length in the transistor. The MBA's took over and engineering terms were replaced by marketing terms!

You build them out. Amd is already doing it. Their EPYC processor has 9 silicon die in one package. They have also recently announced of a working CPU with silicon die stacked on top of another. One interesting about microchip is that only a very thin layer of it is functional the rest is just bulk silicon that can be removed without a problem. So if you grind out the non functional silicon and start stacking up there is a lot more room for more transistors.

128 bit isn't twice 64 bit. it's 64bit^2. And you would more than double the traces (inside and outside) the chip and essentially add orders of magnitude of complexity without any real need. 64 bit is already capable of adressing 18 exobytes. that's 18 thousand petabyte or 18 million terabytes. IIRC there is 40 terabyte HDD for servers expected soon. 64 bit could handle about 450 thousand of them. For 128 bit you're looking at storing one bit per atom and need the entire earth for storage.

GPUs use relatively simple cores that are neither ARM/x86-x64/RISC-V. They are “in order” execution cores that are designed to do specific tasks, with each taking up as little die space as possible. It is the parallel nature of these cores (many 100s or 1000s of them) that make them so efficient at certain tasks.

At 63 instructions just for the base, not including extensions, it's something of a misnomer to call RISC-V a REDUCED instruction set. I'm an old Z-80 programmer, and to me, that instruction set was huge, too. I didn't use 20% of it in actual practice. I have designed an ISA with only 16 instructions, and they're ALL useful. As a coder, I'd much rather have an ISA I use 100% of than anything else I don't use a fifth of.
Daniel Skinner

You are confusing what the REDUCED is referencing. It does not mean "reduced number of instructions", it stands for "reduced instruction complexity". Gary has videos that explain exactly what RISC stands for and the conceptual implications. He even put a quick overview of it in this video. If you really want it you can look for his video on SISA, if you really want a minimal ISA, that you use all 100% of all instructions, 100% of the time.

I really would like to have a PC with RISC-V ISA, FPGA, Vector and x86-64 ISA extensions for legacy compatibility similar to what apple achieves with their arm ISA M1. It is amazing how that chip runs Tomb Raider by rosetta 2 translation on a much more efficient level. The M1 even beats comparable intel chips with just some 30 Watts. This is crazy and RISC-V is said to be even much more efficient. Just imagine playing AAA console game titles on your smartphone. Also a FPGA of course is needed to be more flexible. PS: I don't know why "Gary explains..." videos have that tendency to spread biased information about RISC-V in favour for arm. Maybe it's because arm is british but politics is a bad advisor in tech subjects as people sadly know. For instance the objections in 19:12 when it comes to so called dangers of forking by new extensions, those points are actually much more obvious for proprietary ISAs. For instance Intel brought up MMX, SSE, AVX etc. behind a patent wall to have a selling point over AMD. Also arm extensions are patented. You are dependent from them all and you get even more incompatibilities also with arm, if you compare old with new arm cpu generations. It is a known fact, that not every x86 App works on amd cpus and 3D Now had also problems to catch up with MMX. It is only for a court settlement that intel and amd agreed on a cross licensing, that we got some fewer problems. Now both of them share the throne but are slowing down real Innovation if people would actually know history. To be fair, Amd seems to be better in that regard. Besides, forking does not necessarily lead to incompatibilities. An ISA is quite similar to an API. And Vulkan proves quite well, that many companies can agree on common standards and share the functionalties in favor to spread the techqnique. For instance ray tracing is agreed upon in vulkan, but how it is achieved can be cooked differently on the gpu and companies can keep their cooking recipes beneath that ray tracing API extension. It is well known from experience, that open source is a major advantage, to spread new technologies. So forking is not something bad. From that, innovation can derive much faster which might be established broadly if proven useful. But with closed source and patented hardware, companies will melk the cow till it dies from old age. The first x86-64 cpu with four cores came out in 2006. Now we got 2021 and four cores are still the standard in cpus. Compare this with the core development of GPUs. So much to the so called disadvantage of forking, which actually means innovating. PS2: Also RISC-V is surely not just interesting for low spec embedded systems as GE often suggests. If this was the case, why intel offered two billion Dollars for SiFive then Intel already got low power embedded devices. In fact RISC-V is that much efficient and powerful and capable, that there are several international plans to build supercomputers with it. So please stop telling people, RISC-V was some kind of a toy for poor royalty free engineers in some small hobby rooms. It is not. It is about billions of dollars and has the potential to revolute the market. Also arm by the way started small and still gets underrated. Only in recent years it draw public attention and made big news.

I guess why people say RISC-V is the "Linux of hardware" is 2-fold: first, the ISA is royalty-free, meaning you don't have to pay anything to be RISC-V compatible. Second, you can add your own custom instructions on top of the RISC-V ISA and their extensions; the only requirement is to fully implement the basic ISA and all displayed extensions, meaning that software written for RISC-V will run on your custom core, even though it won't be using your custom instructions.

​@Gary Explains Apple has an insanely sweet deal compared to everyone else in the industry though - it would _almost_ be correct to say that they get it for free. In addition to that, they sell hundreds of millions devices each year so there's a lot of chips to spread that cost across. With RISC-V this becomes a possibility for a much wider range of companies simply because you don't have to pay that incredibly high entry fee. Also, the two main reasons a lot more companies will build their own RISC-V cores are that they can: * Make a completely custom architecture to fit their exact needs without paying through the nose for an Arm architectural license, and even extend it with custom instructions if they need to (Arm recently introduced this as a new feature, as a direct response to RISC-V competition) * The lack of royalties improves profit margin for low cost devices. Obviously this becomes a question of whether to spend a lot of engineering hours on designing and verifying your own core vs. paying someone else to do it for you, but if you ship enough units the up-front cost of engineering can be smaller than the running cost of royalties per chip sold - plus it only improves over time if you can use the same core design (with minor updates) for future products.

The appeal for RISC -V right now is extensionality. For example Jim Keller is currently working on AI microchip with graph cores. This are AI accelerator but it needs a general purpose processor to handle other task and housekeeping. RISC-V allows him to take the base ISA which very simple with only 48 instructions then he can add extensions that do AI acceleration. He can do it with ARM but ARM is design to do other things so ARM processors have transistor circuits that is not needed. Those transistors could be use for more AI accelerator.

People seem to think that this is about "beating Intel" (even though its only thanks to AMD that x86 caught a second wind) but that is never going to happen. Intel made cpus before x86, they will make them after too. By investing in RISC V they can keep ARM from gaining a total monopoly on the efficiency market and have a plan ready if the desktop world finally wants to move to reduced intsruction sets. I still think x86 will be ruling the high performance market for the forseeable future though. For the same reason it is now. Its simply easier to just make a faster one than to replace the whole infrastructure around it, and the penalty for emulation is too high. People downplay PCs importance today because they have lower sales than mobile devices, but there are still more PCs in the world now than ever and the number keeps growing. You can't keep a phone 6-7 years but a PC you can easily nowdays. Apples to oranges.
