But why? Why is it more energy efficient to break a task (instruction) up into multiple steps instead of having the complicated task supported directly as one operation in hardware?
if processing units only need to do a few things really well, they waste less space that would have to be dedicated to complex operations. you can have fewer transistors doing the same amount of work designs that add more and more transistors are both less optimized on a technical level and suffer more from heat buildup, both working against efficiency
In future if ARM totally destroys x86, will the GPU which in PC's are sold separately by Nvdia & Amd will it be replaced by Arm because it's an SOC & Apple already proved that rendering speed in M1 chips are very fast in their own software and in 3d party softwares ?¿
Currently, yes, because game companies target x86 / x64. But make no mistake, x86 is nerfed because it has to maintain backwards compatibility back to the 90s (seriously). Not sure what Microsoft has planned, but I know they need to do something. RISC-V, ARM, whatever they need to do, it is time to break up with x86
buddy. ARM is super under-powered. You even showed why in your video. RISC cannot beat CISC when doing high end tasks. Apple has already maxed out how fast you can push ARM. The M2 is slower then the M1 ultra. en.wikipedia.org/wiki/TOP500 if you look here you can see that the fastest ARM super computer has about 7.5 million cores and 1st is an X86 CPU that has 500 thousand cores. That's less then 25% the amount of cores the ARM one has yet it outperforms it. ARM will never compete in the high end market. And it's even about to be replaced in the low end market by RISC-V. Also, even if ARM was better it'd be hell for custom builders workstation users big companies etc because picking the right specs would be harder because it'd be and SoC. Buying a motherboard would probably also come with the CPU if we used ARM. And even if you managed to make PGA and LGA arm motherboards, each motherboard will still only be able to do very select certain CPUS rather then the form factor IBM invented where almost everything can be changed and swapped out. ARM is also not new, It's just as old as X86. Your chances are better with RISC-V if you want to beat x86. I don't think any RISC CPU could beat a CISC one though, but who knows, RISC-V might surprise us, but I know for sure ARM isn't the future. Although I'm not a fan I respect you and your channel. But please don't push the false narrative that ARM is the future.
Thanks for the comment! Just a few points to make sure we are on the same page, M2 doesnt replace the M1 Ultra. Thats like saying the 12400 is slower than the 11900. The M2 isn't to replace the M1 Ultra. There will be an M2 Pro, M2 Max and an M2 Ultra. The M2 is like an i3 in Apples line up so of course its going to be slower than last years top end chip from Apple but that would be the same from AMD and Intel. Hope that makes sense :) RISC-V is the next step, same with X86 and x86-64, I should have made myself clearer in the video, I was referencing the general technology, not saying RISC specifically but its line, similar to x86 and its line. Sorry about that. Also I never pushed any false narrative of ARM. The line I think you misheard was " However, one runs more efficiently than the other which is why many believe ARM will be the future of computing and will remain the architecture of choice for the smartphone industry for the foreseeable future. " I didnt say I think it would be and I also mentioned nothing about I think it will replace high end PCs. There are other points you mentioned which are interesting, but also remember that many big companies have chips made specifically for their uses so if ARM is easier to design and is more power efficient then they may opt for it once the technology has matured in the workstation space. Right now my guess would be that smartphone development of ARM is much larger than workstation applications as compared to x86 etc but this is just a guess. For now, Apple thinks ARM is the future for their computing including their Mac Pro line (whenever they will launch it lol) but thats not to say AMD or Intel are looking at it the same way, the winner will probably be who ever spends the most! Although, rumours do point to both companies looking into it. ARM could be the future for laptops (due to performance per watt ie better battery for the performance) but thats not to say every single computer will be ARM! similar to electric cars! Some think its the future while others disagree, its all an opinion up until that point! Thanks for the comment again and I hope I cleared things up! Sorry for the long message, might be the longest I have ever wrote! Edit: M2 isn't to replace the M1 Ultra ( mistyped)
@@SabrentUSAOfficial you make a great point. however you give too big of a hand to ARM and SoCs. RISC and CISC in modern are much more similar to one another then they were back in the 80s. both ARM and x86 come from the 80s. the way they got to where they are now is by getting a ton of additions and extensions. they are both old and bloated though. ARM is already at its limit with apple’s M CPUs. the ultra is 125% the size of a threadripper and still gets insanely hot. x86 with intel’s alder lake is also very poor quality. AMD will likely make the final good x86 CPUs for the next 2 generations. ARM has elements of a RISC version up to 4 making it messy and old. with RISC-V it’s possible the integrate a more elegant slim version of x86-64 and its functions allowing it to operate like one but less power consuming and hot. this is possible because RISC-V is a very open thing. RISC-V is very likely to replace ARM and x86. but youve got to be shitting me if you think and ARM SoC is the future. Once again i respect you and your channel but this video is misleading
I think I am being too general which may cause some confusion, I think I may need to be specific. I am talking about ARM and ARM like chips which includes RISC-V. Basically chips that isn’t x86 and uses RISC fundamentals. I am talking about the overall technology, not the specific brand as such. Yes RISC-V is open vs ARMs closed source approach. I think we both agree actually but maybe I wasn’t specific enough, this video was meant to be for beginners and to break down the fundamentals rather than taking a deep dive into every aspect. Maybe I should make another video breaking this down further like a ARM vs RISC-V video or something? I think the video is very good and we did get very good feedback but I appreciate that you didn’t like this video.
If you want to know my own personal opinion, not speaking for anyone, yes I definitely think RISC-V will over take ARM if they can attract the right major companies, I mean it’s already happening so ARM should be worried but I do think RISC-V will overtake CISC in the future too haha but that’s just my take on it, but this video isn’t about my personal opinion on this stuff
@@SabrentUSAOfficial it makes more sense knowing that this video was for starters. Sorry if i came off as aggressive. Another video could be made where you could make predictions and talk about the likely outcomes since this video kind of makes it seem like everything will be ARM soon and i know that wasnt your intention, but with bigger fish spreading false information *cough* (linus tech tips) this could be seen the wrong way to certain people. I like the way you explained a lot of things in this video though so props to you for that.
I don't think it's that simple. We know that special purpose hardware (like ASICs) can flatten CPUs head to head, so the idea of CISC can't be all wrong. And ARM has now a fairly complicated instruction set. Maybe the CISC instructions are mismatched to needs, maybe it all comes down to the uniform size of the ARM instructions, and maybe it comes down to subtleties of the hardware that nobody outside TSMC and Intel could explain.
Dear author thank for providing the clarity. I recently shift windows environment to Mac environment i have a bit doubt. I have M2 Macbook Pro. I found some tools avail in aarch64 & x86. Both are work in my macbook. Do you have any recommendations. Which aarch should i use & why? Arrch64 or x86
