China is doubling down on the RISC-V architecture.
You must log in or register to comment.
They’ve been spending tens of billions a year in their chip industry.
and, honestly, RISC-V is the right place to spend it. RISC has super powers.
What do you mean by that. RISC-V is open source but it doesn’t have “superpowers” that I know of?
“reduced” is the super power. I would much rather put the smarts into the assembler/compiler/interpreter than the silicon. have been followed RISC since the 80’s and discovered that I am really a RISC guy living in CISC world. open arch is the world dominating cherry-on-top.
Do you have any resources by any chance that explain the difference well?
I work in high level software, so understand the benefit of doing things at ide time vs compile time vs runtime, and I’ve coded in assembly back in the day and understand instruction sets at a very rough level, but I’m not really familiar with specifically what differentiates RISC / ARM / x64, or why RISC’s reductions would be good / bad / what trade-offs come with them.
between the 30k’ overview of Reduced instruction set computer (RISC) architecture and the lower level RISC-V Architecture: A Comprehensive Guide to the Open-Source ISA, you should get a pretty decent feel for it.
the level of optimization you get via hardware and software tooling is honestly pretty spectacular. I have been waiting for RISC to come out of hiding for years and it seems to be happening.
Love it!
Yeah, RISC is good.
Triple the speed of a Pentium…
Edit: it was triple I said double originally. I’m sorry for my indiscretion.
Wow, all the down votes. Youngin’s don’t know what they’re missing. Classic film.
About that last sentence about software support determining the future of risc-v. It will overtake x86 (eventually) just due to the nature of OSS. At first OS platforms arent as good… Until suddenly they are. Ask Apple. When the iPhone first launched, it was a million times better than Android. And yet now they are totally on par with each other. And Android has the edge in a lot of cases.
Lol
This could be great news. RISC5 could be great for diversity in the processor space. I at will take investment on the scale that only a national investment like China can invest to get it to compete.
Does China have the Fab capability to build these, or do they need foreign production?
They have been making their own x86 knock-offs for a while now, but not at the same scale as the “regular” - i.e. they’d been doing it at 14nm or so, so less efficient.
I don’t know if they have better fab process since then, and for how big a scale.
Their x86 fabs are producing a 5 yr old Intel node, and with unknown defect rate. This is about getting down to the modern node size to (eventually) to get competitive with the two major ARM nodes.
Seems like it’s specs are still unknown?
Any benchmarks? Seems like it bundles NN acceleration that competes with GPUs, but benchmarks/price matters.

RIVAI claims that the Lingyu processor’s computational performance rivals that of major international server chips from Intel and AMD.
Fine, they’ve made a processor, but until I have an idea of how well tested and secure it is, I’m not running anything on it. I don’t mean in a “Oh China, scary!” way but just because it’s an unknown brand with no track record.
Making something that works most of the time is one thing. Making something bulletproof is another.
…and they’re positioning this for servers.
Sorry to inform you, but all of our infrastructure runs on layers of hacks already.
this is so deliciously and disappointingly true. :-/
