Intel Xeon Platinum 8151

12C/24T · 4.0 GHz · 240 W

A 12-core off-roadmap Xeon Platinum model from Intel's first-generation Xeon Scalable family, tuned for very high per-core frequency. It runs at 3.4 GHz base and reaches 4.0 GHz turbo on all cores, with an unusually large 24.75 MB of L3 cache for its core count and a 240 W TDP, which suits licensing-sensitive and latency-bound workloads.
