So is RISC-V taking over then?

[Lord Flashheart]

Nvida tried to get their grubby hands on ARM, which apparently freaked out a lot of companies needing chips.
It has massive support from industry, although still needs a lot of work in terms of software and hardware design.
If anyone cares, it is an alternative to X86 or ARM CPUs, that is the CPU instruction set. Licence free and open.

So presently put into controllers for various componenets.

Will we see a RISC-V based GPU at some point.
Will all PCs use it with X86 emulation down the road.

We will see.
I am no expert on hardware design, but someone who is curious about it.

Not sure if you understand what RISC-V even is, or used for. Sure doesn't sound like it.
Sounds like you need to go on Google and read more about it.

RISC-V is already used in lots of hardware, often in controllers and chipsets.

I am not sure if the major GPU manufacturers will even bother switching to RISC-V for their GPUs themselves, there may be very little benefit for them to do so, since they will have to develop their own RISC-V extensions which is little different from what they are doing now. But they will most certainly adopt standardised controler chips utilizing RISC-V, they actually may already have.

I have a soldering iron running a RV32IMAFC at 144Mhz. This chip is capable of being used as a RISC-V embedded development platform, but it lacks the instruction sets required for a full Linux-based or BSD-variant operating system to run on it.

I also have a VisionFive 2 with a RV64GC at 1.5GHz. This is nice little Raspberry Pi alternative, it is a fully functional computer.

I think it will be at least another 2-5 years before we may see RISC-V seeing mass adoption for general computing, but then we are initially just talking about stuff like Raspberry Pis and various hobbyist machines.

Pine64 will soon make available for pre-order a RISC-V tablet, but this is development stuff, there are no operating systems available for it right now and the Linux support for the hardware at this time is very poor. This device is aimed at operating system developers.

I can't wait for x86 to finally die, it is a horrible instruction set which should have died back in the 1990s, but the Wintel monopoly prevented that from happening.

I am hoping a GPU may eventually appear, maybe by another party. The drivers will be an issue though. It is just speculation on my part. The market needs it.

I know RISC-V chips are being used now. I am not looking to buy a development kit or anything. I think there are linux based operating systems that can run using it. It is a start. Well the more it is adopted, the bigger threat to ARM & X86.
I expect in about 5 years or so, things will look quite different.

Gpus don't really need it when you have the system core chipset and cpu having such a feature. It doesn't need to be implemented in every piece of hardware.

RISC-V is not exclusively a full featured CPU, it is highly flexible and can also be utilized for performing basic and generic workloads for which a full CPU would be overkil and for which right now we are using non-standardized microcontrollers or overkil ARM chips.

For example the GPU needs controllers for power management, this could be done by a tiny little RISC-V-based microcontroller.

RISC-V is very suitable for replacing generic microcontroller chips with a standardized ISA. Within no-time you may find RISC-V in your microwave, and all this chip will be doing is keeping the time, tracking the cooking mode and do a countdown.

Many pieces of modern hardware already have RISC-V inside of them, reasonable chance if you have a modern PC there are some RISC-V components already running inside of it.

The alternative is using a full ARM or MIPS core, which are not as flexible nor scalable as RISC-V.

People running x86 games on RISC-V.

Oh ok so it can be implemented as a small micro-controller on its own. That's good to know. Yes I think that as time passes, depending upon how much longer traditional X86 hardware will remain to be produced we probably will see it used more.
