Intel® Xeon™ 6527P

The Intel Xeon 6527P is a server processor with 24 cores and 48 threads, built on the Granite Rapids architecture. It launched in Jan 2025. Clocks run from 3.0 GHz base to 4.2 GHz boost. A 144-MB L3 cache backs the cores (7.6 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 (88 lanes). Rated TDP is 255 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon 6527P scores 3,539 in single-core performance and 74,445 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 16,231 for overall performance, 53,344 for productivity performance, 47,315 for creator performance, 94,917 for engineering performance and 29,228 for gaming performance. Its multi-core throughput works out to 3,102 per core, 1,551 per thread and 292 per watt. Its computed efficiency index is 1,017. Its performance index is 201, so its overall performance is 101% 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 6527P scores 268,985 in integer math, 195,005 in floating-point math, 1,030,818 in compression, 60,333 in cryptography, 8,037 in physics simulation, 71,600 in vector SIMD, 508 in the prime sieve and 131,597 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 357% above in integer math, 325% above in floating-point math, 352% above in compression, 425% above in cryptography, 637% above in physics simulation, 362% above in vector SIMD, 658% above in the prime sieve and 481% 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 6527P has 24 physical cores and runs 48 logical threads. It runs 2 threads per core. It runs at a base clock of 3.00 GHz and boosts up to 4.20 GHz.

The Intel Xeon 6527P 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 6527P has 1.97 MB of L1 cache, 36 MB of L2 cache and 144 MB of L3 cache. That adds up to about 182.0 MB of cache, or 7.58 MB per core.

The Intel Xeon 6527P has a 3-level cache hierarchy: L1 at 2.0 MB, L2 at 36 MB and L3 at 144 MB. L3 is the largest level and makes up about 79% of the cache listed here.

The Intel Xeon 6527P 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 6527P does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon 6527P uses the FCLGA4710 socket, supports PCI Express 5.0 and provides up to 88 PCIe lanes.

The Intel Xeon 6527P has a rated TDP of 255 W.
