Intel® Xeon™ 6511P

The Intel Xeon 6511P is a server processor with 16 cores and 32 threads, built on the Granite Rapids architecture. It launched in Jan 2025. Clocks run from 2.3 GHz base to 4.2 GHz boost. A 72-MB L3 cache backs the cores (6.6 MB per core). It addresses DDR5 memory up to 4 GB across 8 channels. The chip drops into the FCLGA4710 socket and exposes PCIe 5.0 (136 lanes). Rated TDP is 150 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon 6511P scores 3,025 in single-core performance and 48,786 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 12,148 for overall performance, 35,946 for productivity performance, 32,277 for creator performance, 56,104 for engineering performance and 21,272 for gaming performance. Its multi-core throughput works out to 3,049 per core, 1,525 per thread and 325 per watt. Its computed efficiency index is 992. Its performance index is 151, so its overall performance is 51% above the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

Scores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.

In the individual workload tests the Intel Xeon 6511P scores 165,055 in integer math, 129,282 in floating-point math, 656,927 in compression, 32,287 in cryptography, 4,432 in physics simulation, 52,073 in vector SIMD, 323 in the prime sieve and 70,098 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 180% above in integer math, 182% above in floating-point math, 188% above in compression, 181% above in cryptography, 307% above in physics simulation, 236% above in vector SIMD, 382% above in the prime sieve and 209% above in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.

The Intel Xeon 6511P has 16 physical cores and runs 32 logical threads. It runs 2 threads per core. It runs at a base clock of 2.30 GHz and boosts up to 4.20 GHz.

The Intel Xeon 6511P is a server processor, belongs to the Intel Xeon 6 family, uses the Granite Rapids architecture and carries the codename Granite Rapids. It launched in Jan 2025.

The Intel Xeon 6511P has 1.75 MB of L1 cache, 32 MB of L2 cache and 72 MB of L3 cache. That adds up to about 105.8 MB of cache, or 6.61 MB per core. Each core has 2 MB of private L2 cache.

The Intel Xeon 6511P has a 3-level cache hierarchy: L1 at 1.8 MB, L2 at 32 MB and L3 at 72 MB. L3 is the largest level and makes up about 68% of the cache listed here.

The Intel Xeon 6511P supports DDR5 memory, addresses up to 4 GB of memory and uses 8 memory channels. It does not support DDR4 and LPDDR memory.

The Intel Xeon 6511P does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon 6511P uses the FCLGA4710 socket, supports PCI Express 5.0 and provides up to 136 PCIe lanes.

The Intel Xeon 6511P has a rated TDP of 150 W.
