Additionally, the benchmark was only run on one core, and since the last-generation Kunpeng 920 capped out at 64 cores, this result was likely run on a virtual machine or some configuration where only one core was tested. That in turn means the multi-core score isn't really useful and can't tell us too much about how performant the full chips are.

Unfortunately, without a look at multi-threaded performance, power consumption, and efficiency, it's hard to say how competitive Taishan V120 cores will be. For servers in particular, power and efficiency are key due to the cost of electricity, and even if Huawei's latest server CPUs are fast, that won't mean much if they consume tons of power.

Huawei is China's showpiece, they have a lot of motivation to exaggerate. It's probably not fake, but I do expect this to be a cherry-picked top 1% result.

This is great news though, the more competition, the better.

A cherry-picked top 1% result is sort of what single-core performance is meant to evaluate.

I'm so tired of people trying to ridiculously imply that everything coming out of Huawei is fake. The argument doesn't even make sense as this isn't from Huawei, this is an engineering sample given to an end user.

I realize you're not exactly saying that, but it really gets on my nerves these days. For example, when the Kirin 9000s came out, people were saying Huawei was lying about it being a 7nm chip and that it was made in Taiwan from old stock or whatever. The problem with those claims are the only reason we knew it was a 7nm chip was because a CANADIAN company opened it up and determined it was indeed a 7nm chip. Huawei didn't say anything and people were calling them liars for what Canadians were saying. It's why there was the 4.9999G jokes since Huawei never claimed the 9000s was 5G.

Similarly in this case, it's an engineering sample. Huawei again didn't say anything. If you're going to call someone a liar the person you're accusing should have at least said something.

It seems I misunderstood the situation. The Twitter user in question that uploaded the results seems to specialize in tech leaks. There's a decent chance that this wasn't even green lit by Huawei.

Yeah, I know you probably didn't mean to imply that. To be honest in some ways I was using your post to soapbox. Just tired of people calling Huawei a liar when they literally didn't say anything.
