Why No new cpu,gpu companies are not coming

[BeefyTank77]

I just wanted to know

What do you want to know? can you better formulate your question?

I think he wants to know why there is no new companies, besides Intel, Nvidia and AMD, making GPU and CPU ?

For cpus, i know that intel and amd have a contract that makes x86-64 exclusive to them

[sphbecker]

Chip design has a very high barrier to entry. Huawei (I think, might be a different Chinese company) is also working on a GPU, but it isn't targeted for the US. Once Intel and Huawei hit the market, that means we will have 4 GPU makers, which is enough for real competition.

The x86 and AMD64 instruction sets are represented by thousands of patents held by several difference companies. Anyone seeking to make a chip would have to pay royalties. Intel and AMD pay each other small amounts of money for each chip they make. A new comer would have the same options, but Intel and AMD would probably do whatever they legally could to make it hard for them.

 

Also, these days, RISC chips work in more and more situations, so that is always an option if you can't get the rights to others.

I know ARM chips are slowly climbing their way up

If this is asking why no one else is making another CPU or GPU, it depends on where you're looking, If we're talking about high performance applications like servers and desktops, it's because there's a massive barrier of entry. You're going up against contenders who've been in the game for 20+ years. They know what works, they know some of the best way to do things, and many of those ideas are patented. So you can either license one of these companies' designs, or find a way to catch up to those 20+ years of experience.

 

For lower end markets though, for CPUs that power most of the electronics we use, you can get away with simpler CPUs. While ARM has taken over the general purpose microcontroller market, there's still specialized chips and other components that may contain custom, but simple CPU cores.

[Mister Woof]

Huge amounts of cost for patents/royalties, R&D, technical talent required, fabrication, etc.

 

It's just too hard to get into the game and would take decades to become profitable.

 

It doesn't seem like a market space that's worth venturing into.

 Thanks for info

look up ARM and RISC-V

they're coming, if not already here (in ARM's case, in your phone already)
