RISC-V is an alternative microprocessor technology to x86 and ARM, with its instruction set architecture (ISA) being open rather than closed. This video explains what RISC-V is all about, including its origins, key market players, hardware, applications, intellectual property (IP), and the likely role of global politics and international trade barriers in determining RISC-V's success.

#RISC-V #x86 #ARM #ExplainingComputers
2 years ago you predicted the exact future man. Now days, Nvidia and others(Qualcomm, google and samsung) are trying to kill AMD and INTEL(X86 , ARM) from the game and relay on RISC-V INSTEAD.

Linux developers should already support openess.

MIPS refurbished.
@jesperjuhlhansen3773 Says:
RISC-V was incorporated into MIPS Processors back in the 90's and 2000's in Silicon Graphics Workstations and even some Cray Supercomputers.. Sony Playstation used MIPS in their first edition.. Sun Microsystems used also RISC-V in their Sparc Processors
@isbestlizard Says:
Qualcomm just learned the downsides of using a closed ISA... expect them to go ball deep on RISC-V after this wakeup call :D

The board does not seem to have a VGA or HDMI port. How to you connect it to a display here?

@fridaycaliforniaa236 Says:
I always thought it was RISC-V, but actually it's « RISC 5 » XD I'm dumb...
@danh5637 Says:
I don’t understand how Berkeley came up with RISC but Acorn basically overtook them with ARM and RiscV is very sloppy and slow in comparison. It maybe open, but it’s still crap. And they ought to have been way ahead as they had such an advantage on ARM by inventing the basic premise.
@danh5637 Says:
Aren’t we on the verge of moving into quantum computing age? Seems somewhat moot at this juncture.

We all love (Free and Open Source).. and So do Hackers.. Using the RISC-V for some applications (You Could be Taking the Risk) of easely being Hacked..

@andrewwebb9426 Says:
I can see that ‘politics’ of various sorts seems to dominate this discussion. There’s the politics of open vs closed, the little guy vs the big guy and, of course, real geopolitics. But I thought the whole point of RISC was that it could theoretically make computing more efficient in the energy-use sense? That is, it could make data centres less hungry for energy and cooling water etc. RISC could make laptops and tablets have longer battery life and less dependent on scarce elements. These seem to me far more important than the politics. Yet nobody seems to mention this, now. Haven’t you all lost sight of the main picture as you get all excited about a new technology?
@mankaner Says:
redo this in a ganster voice please. Since we still on the x86 bus. I will only take you seriously then.
@JushBJJ Says:
Working on RISC-V with tenstorrent chips atm 👀
@posmoo9790 Says:
you didn't explain anything
@zytr0x108 Says:
An open ISA is great. But it should’ve used a copy-left license to make sure the implementations have to be opened too.
@subbastionbastion2167 Says:
You didn't convince anyone besides legal mumble jumbo that risc-v is better then arm therefore arm is the future. I think countries will ignore the legal and just produce arm chips with or without a license paper
@tigerscott2966 Says:
That sounds really useful...as long as I can run Linux on it, I am happy!
@armisis Says:
Just got my Milk-V Meles got it to boot... I see the potential just needs more love from different OS.

I am originally from Romania and I live in UK and I have enough knowledge about China because of communism and this war between USA and China is absolutely stupid. I remember very clearly that China was a poor country and it used to depend on exports from Eastern Europe, just because a country like China wants to become developed, nations like the US start to create all sort of barriers without considering the positive social impact of Chinese infrastructure, it is as if the US is acting in a dictatorial way and it does not take a lot of political knowledge to understand this.. Huawei did great things because it helped poor countries to have internet access and I believe that one day China will manage to hold the position of Japan because the quality of goods is increasing a lot and the recent takeover of Hong Kong and all of their social systems will benefit China a lot in establishing a better social structure that can enable development. The US is acting like a kid who is jealous because others are developing high technology, it is just unbelievable.
No, RISC-V is not free, they have Licenses too, for the use of the different modular ISAs; what is free is the use of those ISAs in CPU Architecture Designs, 'coz there's no Architecture to License, only a basic Open template.
ARM 2024: Snapdragon X Elite for Laptops is here, that runs Windows well, and probably PCs in the future. NGreedia could jump from Server CPU to PC CPUs; Lots of Smartphones use ARM. So RISC-like CPUs are here to stay, and eventually will displace x86 if they stay Microcode-Free Direct Wired and getting smart ISAs with RISC-like efficient execution, which gives also low Power consumption; this means that RISC-like Architectures are simply are more Efficient in every way, so by natural selection, they'll become better and one day people will simply won't pick up x86.
The next 10 years are going to be revolutionary in the CPU Industry I think too
@jakobw135 Says:
Does Linux use Risc5 architecture?
@Hunter_Bidens_Crackpipe_ Says:
RiscV is far superior to ARM
@rnssr71 Says:
no love for POWER?
@12q8 Says:
Yeah, I agree. Especially since RISC-V doesn't require licensing.
Another thing is as you mentioned, it won't happen ubiquitously, but rather in some areas faster than others, and x86 and ARM would try to stay competitive by maybe lowering their fees and or even making it open-ish.
@nessim.liamani Says:
The Management Engine (ME) is a feature found in Intel CPUs, while AMD's equivalent is known as the Secure Technology, which encompasses features like the Platform Security Processor (PSP). These components are embedded subsystems within the CPU that operate independently of the main processor and have privileged access to system resources.
Their primary purpose is to provide system management functions, such as remote administration, system recovery, and security features like hardware-based encryption. However, they have also raised concerns about potential security vulnerabilities and backdoor access.
Critics argue that because these subsystems operate independently and have access to sensitive system functions, they could be exploited by malicious actors, including government intelligence agencies, to gain unauthorized access to systems for surveillance or other purposes. This concern stems from the fact that the ME and similar features are proprietary and closed-source, making it difficult to audit and verify their behavior.
As a result, there have been calls for greater transparency and security measures to mitigate these potential risks. Some users and organizations opt for hardware models that either disable or limit the functionality of these subsystems, especially in high-security environments. However, the availability and effectiveness of such measures vary, and they often come with trade-offs in terms of system functionality and performance.
