Intel® Xeon™ 6548P-B

The Intel Xeon 6548P-B is a server processor with 32 cores and 64 threads, built on the Granite Rapids architecture. It launched in Oct 2025. Clocks run from 2.0 GHz base to 3.5 GHz boost. A 128-MB L3 cache backs the cores (4.0 MB per core). It addresses DDR5 memory up to 1157.12 GB across 4 channels. Rated TDP is 195 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon 6548P-B has 32 physical cores and runs 64 logical threads. It runs 2 threads per core. It runs at a base clock of 2.00 GHz and boosts up to 3.50 GHz.

The Intel Xeon 6548P-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 6548P-B has 128 MB of L3 cache. That adds up to about 128.0 MB of cache, or 4.00 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Xeon 6548P-B supports DDR5 memory, addresses up to 1,157 GB of memory and uses 4 memory channels. It does not support DDR4 and LPDDR memory.

The Intel Xeon 6548P-B does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon 6548P-B supports PCI Express 5.0 and provides up to 48 PCIe lanes.

The Intel Xeon 6548P-B has a rated TDP of 195 W.
