Tom's hardware got hold of the Sapphire Rapids 52-core Xeon Platinum 8470 and tested it against a... Threadripper 3990X.

The result, which TH describes as "demolishing the Threadripper", is under closer scrutiny pretty bad for Intel.

The only really good result of SR was CPU-Z, where the 52-core chip beat the old Threadripper by a whopping 70%. But The V-Ray and Cinebench results are much worse, beating the old AMD CPU by just 3% (V-Ray), 6% (R23) and 17% (R20), while the Threadripper even won out the Cinebench R15 comparison by 12%.

So, why are these numbers disastrous? Well, for one, they're against Zen 2, not the current Zen 3 and definitely not against Sapphire Rapids main competitor, which will be Zen 4. The margins are very small, so against the current Epyc Topmodel, Sapphire Rapids can at best keep up in most tasks while both are trading barbs in some applications. Zen 4 should make minced meat of Sapphire Rapids, even just the 64-core chips and not the 96-core high-end models. Finally, the SR chip is at a 350W TDP, so it really should beat a 3 year old CPU with a TDP 70W lower than his own. That it only manages to barely do so is damning in it's own right.
