Intel® Xeon™ 6377P

The Intel Xeon 6377P is a server processor with 12 cores and 24 threads, built on the Raptor Lake architecture. It launched in Apr 2026. Clocks run from 3.1 GHz base to 5.7 GHz boost. A 36-MB L3 cache backs the cores (3.0 MB per core). It addresses DDR5 memory up to 128 GB across 2 channels. The chip drops into the FCLGA1700 socket and exposes PCIe 5.0 (20 lanes). Rated TDP is 95 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Xeon 6377P has 12 physical cores and runs 24 logical threads. It runs 2 threads per core. It runs at a base clock of 3.10 GHz and boosts up to 5.70 GHz.
