Intel® Xeon™ 6774P

The Intel Xeon 6774P is a server processor with 64 cores and 128 threads, built on the Granite Rapids architecture. It launched in Apr 2025. Clocks run from 2.5 GHz base to 3.9 GHz boost. A 336-MB L3 cache backs the cores (7.4 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 350 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon 6774P scores 3,047 in single-core performance and 112,749 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 18,535 for overall performance, 77,553 for productivity performance, 67,497 for creator performance, 157,849 for engineering performance and 37,328 for gaming performance. Its multi-core throughput works out to 1,762 per core, 881 per thread and 322 per watt. Its computed efficiency index is 991. Its performance index is 230, so its overall performance is 130% 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 6774P scores 593,440 in integer math, 465,314 in floating-point math, 2,309,868 in compression, 115,025 in cryptography, 16,023 in physics simulation, 177,273 in vector SIMD, 1,264 in the prime sieve and 262,417 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 908% above in integer math, 914% above in floating-point math, 913% above in compression, 901% above in cryptography, 1,370% above in physics simulation, 1,043% above in vector SIMD, 1,787% above in the prime sieve and 1,058% 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 6774P has 64 physical cores and runs 128 logical threads. It runs 2 threads per core. It runs at a base clock of 2.50 GHz and boosts up to 3.90 GHz.

The Intel Xeon 6774P 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 Apr 2025.

The Intel Xeon 6774P has 7 MB of L1 cache, 128 MB of L2 cache and 336 MB of L3 cache. That adds up to about 471.0 MB of cache, or 7.36 MB per core. Each core has 2 MB of private L2 cache.

The Intel Xeon 6774P has a 3-level cache hierarchy: L1 at 7 MB, L2 at 128 MB and L3 at 336 MB. L3 is the largest level and makes up about 71% of the cache listed here.

The Intel Xeon 6774P 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 6774P does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon 6774P uses the FCLGA4710 socket, supports PCI Express 5.0 and provides up to 136 PCIe lanes.

The Intel Xeon 6774P has a rated TDP of 350 W.
