Impressive Sapphire Rapids Xeon W9-3495 with 56 cores and 112 threads spotted in bootlog: Clocked at 1.8 GHz with AVX instruction support

Tipster @InstLatX64 recently unearthed what appears to be an upcoming Intel Sapphire Rapids HEDT CPU out in the wild, while digging through publicly-available Linux bootlogs. This CPU, the Intel Xeon W9-3495, is a single-socket solution with 56 cores and 112 threads, clocked at 1.8 GHz.

Earlier rumors indicated that Intel's much-delayed Sapphire Rapids HEDT workstation lineup would come in two lineups: "Expert" and "Mainstream". The former would top out at 56 cores and 112 threads, while the latter would scale all the way down to 12 cores for mainstream workstation setups. While Intel started sampling of Sapphire Rapids chips a year ago, this is the first confirmation we have about the top-tier Expert chips.

The Mainstream Xeon W5-3433, with 16 Golden Cove cores, 32 threads, and 45 MB of L3 cache leaked was spotted earlier in the SiSoft Sandra database. The W9-3495 is a significant step up. The chip supports both AVX-512 and AMX instructions, offering major performance gains in specific use cases, at the cost of higher power draw and temps. 

While it's clear that higher-end Sapphire Rapids CPUs are out in the wild, we still don't have a clear timeframe for when these HEDT chips will launch.
