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.
