Intel® Xeon™ 6745P

The Intel Xeon 6745P is a server processor with 32 cores and 64 threads, built on the Granite Rapids architecture (Intel 3 process). It launched in Jan 2025. Clocks run from 3.1 GHz base to 4.3 GHz boost. A 336-MB L3 cache backs the cores (12.6 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 300 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon 6745P scores 3,450 in single-core performance and 84,210 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 17,045 for overall performance, 59,567 for productivity performance, 52,526 for creator performance, 117,894 for engineering performance and 31,403 for gaming performance. Its multi-core throughput works out to 2,632 per core, 1,316 per thread and 281 per watt. Its computed efficiency index is 984. Its performance index is 211, so its overall performance is 111% 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 6745P scores 336,926 in integer math, 267,438 in floating-point math, 1,352,801 in compression, 66,665 in cryptography, 6,144 in physics simulation, 108,326 in vector SIMD, 681 in the prime sieve and 133,528 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 472% above in integer math, 483% above in floating-point math, 493% above in compression, 480% above in cryptography, 464% above in physics simulation, 598% above in vector SIMD, 916% above in the prime sieve and 489% 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 6745P has 32 physical cores and runs 64 logical threads. It runs 2 threads per core. It runs at a base clock of 3.10 GHz and boosts up to 4.30 GHz.

The Intel Xeon 6745P is a server processor, belongs to the Intel Xeon 6 family, uses the Granite Rapids architecture, carries the codename Granite Rapids and is manufactured on a Intel 3 process. It launched in Jan 2025.

The Intel Xeon 6745P has 3.50 MB of L1 cache, 64 MB of L2 cache and 336 MB of L3 cache. That adds up to about 403.5 MB of cache, or 12.61 MB per core. Each core has 2 MB of private L2 cache.

The Intel Xeon 6745P has a 3-level cache hierarchy: L1 at 3.5 MB, L2 at 64 MB and L3 at 336 MB. L3 is the largest level and makes up about 83% of the cache listed here.

The Intel Xeon 6745P supports DDR5 memory, addresses up to 4 GB of memory and uses 8 memory channels. It does not support DDR4 and LPDDR memory. It supports ECC memory.

The Intel Xeon 6745P does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon 6745P uses the FCLGA4710 socket, supports PCI Express 5.0 and provides up to 88 PCIe lanes.

The Intel Xeon 6745P has a rated TDP of 300 W.
