EDIT: Sorry, not SnapdragonX - apparently I can't read.
Also, who is "MetaComputing" and can I trust them with my money? Something about the big "Web 3 Integrated Devices" branding on their landing page makes me less than enthusiastic. Otherwise I'd be hovering over 'buy'
This is an overstatement so gross that it can be considered false. On Skylake-X, for mixed workloads that only had a few AVX-512 instructions, a net performance loss could have happened. On Ice Lake and later this statement was not true in any way. For code like ChaCha20 it was not true even on Skylake-X.
