News Alibaba's Yitian 710 is the fastest Arm-based CPU for cloud servers, study claims

[Admin]

Study shows that Alibaba's 64-core Yitian 710 outperforms Amazon's Graviton 3, Huawei's Kunpeng 920, and Ampere's Altra 80-core processor.

The actual article is paywalled, so I have to rely on the graphs in the Register.

I think many of Alibaba Yitian's wins in some benchmarks can be attributed to it simply running at a higher clock than the ARM competition.

 

[Alvar "Miles" Udell]

Not entirely unsurprising, ARM vs x86 and all that, but how do they perform in real world workloads?

Uh-oh, watch out Alibaba, the hammer might come for ya…real soon!

 

[Amdlova]

On server side claims are "only show this perfect side". On real world it's another thing.

It will be okay guys. It will probably be an non-Chinese ARM processor next time.

It is not our faults their government runs their op like they do. If they were a little more open with some stuff, maybe it would be easier to believe things like this are wholly legitimate.

Until the rest of the world can test these claims, we have to assume they're not entirely kosher.

I really do not care whom creates the technology that will drive our future. I just want it to be cost effective for end-users and deliver the performance we should expect from newer generations of technology.

The rich and powerful will get the backdoors or access they want into these systems regardless of who makes the physical kit. We need to let go of that, as the horse has long left the stable of personal privacy. Not like most of us care about it anyway, as long as we can get on the latest social media app and get in on the latest fad.

Did you see who ran the test?

Alibaba Cloud's 128-core Yitian 710 processor ... compared them against the Intel Xeon Platinum 8488C

The 8488C has only 48 cores (96 threads)! For sufficiently scalable tasks, it's better to have more cores, even if they're much simpler.

synthetic Dhrystone and Whetstone benchmarks

These are no longer commonly used, since they don't tend to reflect common workloads.

This just needs a cache optimization, similar to what Ampere's Altra had.

RSA 2048 signing and verification tests.

This could benefit from a hard-wired crypto accelerator. Does it have them?

two Kunpeng 920 CPUs can run in a Non-Uniform Memory Access (NUMA) topology, a capability unmatched by any other cloud provider's Arm servers.

Ampere's Altra can do that.

Did you see who ran the test?

Yes, and as bit_user has pointed out, their information is invalid, to say the least.

I have no problem believing a chinese firm can develop a chip that could rival western firms, but can they do it at scale reliably? This, i'm not confident in.

 

[bit_user]

Yes, and as bit_user has pointed out, their information is invalid, to say the least.

I was trying to make the case that it was irrelevant, not invalid. In other words, I don't dispute the results they found on their chosen test suite, but I consider the test suite either not to match modern cloud workloads or simply to be ones which favor a greater number of simple cores vs. fewer that are more sophisticated.

The narrative of the piece seems to imply that this CPU was far ahead of its time, which is the main point I dispute. However, that doesn't mean it wasn't a milestone. If they managed to deploy 128-core ARM CPUs before Ampere, that would've been a nice achievement, in itself.
