For Cisco, their press releases seem to be here: https://newsroom.cisco.com/pressreleases
I haven't looked through all of them because I'm lazy, but scrolling through them I haven't yet found one that isn't in the 3rd person.
And if you go on Google and search some text from a press release, you'll find tons of articles using the headline and body completely verbatim like it's their own article. This is intentional.
Because that's how you do press releases.
News outlets print them verbatim, and it's traditional to read like that (as opposed to e.g. "we released a CPU" which on a news outlet it would make it seem like the outlet's team released the CPU").
Fujitsu's A64FX is 7nm-class, and has those SVE extensions for incredible throughput. It is expected to be in several supercomputers soon.
I expect that the A64FX is the fastest ARM in the world.
The big questions involve how Huawei's 8 DDR4 channels compare to Fujitsu's 4 HBM2 banks, how Huawei's 64 cores compare to Fujitsu's 48.
Even if their IP is worse, they seem to have brute-forced their way to the top.
