Intel® Xeon™ 6768P-B

The Intel Xeon 6768P-B is a server processor with 64 cores and 128 threads, built on the Granite Rapids architecture. It launched in Oct 2025. Clocks run from 2.2 GHz base to 3.5 GHz boost. A 256-MB L3 cache backs the cores (4.0 MB per core). It addresses DDR5 memory up to 2304 GB across 8 channels. The chip drops into the FCBGA5026 socket and exposes PCIe 5.0 (48 lanes). Rated TDP is 325 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon 6768P-B has 64 physical cores and runs 128 logical threads. It runs 2 threads per core. It runs at a base clock of 2.20 GHz and boosts up to 3.50 GHz.

The Intel Xeon 6768P-B is a server processor, belongs to the Intel Xeon 6 family, uses the Granite Rapids architecture and carries the codename Granite Rapids-D. It launched in Oct 2025.

The Intel Xeon 6768P-B has 256 MB of L3 cache. That adds up to about 256.0 MB of cache, or 4.00 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Xeon 6768P-B supports DDR5 memory, addresses up to 2,304 GB of memory and uses 8 memory channels. It does not support DDR4 and LPDDR memory.

The Intel Xeon 6768P-B does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon 6768P-B uses the FCBGA5026 socket, supports PCI Express 5.0 and provides up to 48 PCIe lanes.

The Intel Xeon 6768P-B has a rated TDP of 325 W.
