China boosts in silicon...

Post by smatovic » Sat Dec 14, 2019 7:36 am

You may have read it, China wants to get independent from Western chips and
software within 3 years. So what does China have in hands concerning CPUs?
Here a little overview...

x86-64 - THATIC, a joint venture with AMD

x86-64 - Zhaoxin, a joint venture with VIA

https://en.wikipedia.org/wiki/Zhaoxin

MIPS64 - Loongson/Godson CPU

https://en.wikipedia.org/wiki/Loongson

SPARC - Galaxy CPU used in Tianhe-2 supercomputer.

Accelerator - Matrix 2000 used in Tianhe-2 supercomputer

RISC - Sunway SW26010 with own ISA used in Sunway TaihuLight supercomputer

https://en.wikipedia.org/wiki/Sunway_SW26010

RISC-V - Xuantie CPU by Alibaba

ARM

From Huawei mobile chips, over Phytium desktop cpus, to Alibaba server chips
there are many IP licensees.


Personally I would bet on the RISC-V ISA in the long run.

Hmm, things are getting interesting...

TSMC cuts off Huawei from chips from September on:

Nvidia may buy ARM from SoftBank:

It seems SMIC (Shanghai) is still on 14nm FinFET:

Question remains open on which ISA/architecture China will bet, AFAIK RISC-V
still has no SIMD/Vector units defined for number crunching and alike.
