Intel® Xeon™ 6740P

The Intel Xeon 6740P is a server processor with 48 cores and 96 threads, built on the Granite Rapids architecture (Intel 3 process). It launched in Jan 2025. Clocks run from 2.1 GHz base to 3.8 GHz boost. A 288-MB L3 cache backs the cores (8.1 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 270 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon 6740P scores 2,975 in single-core performance and 88,061 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 16,186 for overall performance, 61,405 for productivity performance, 53,789 for creator performance, 123,285 for engineering performance and 30,940 for gaming performance. Its multi-core throughput works out to 1,835 per core, 917 per thread and 326 per watt. Its computed efficiency index is 985. 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 6740P scores 388,500 in integer math, 296,102 in floating-point math, 1,537,129 in compression, 82,028 in cryptography, 9,705 in physics simulation, 116,992 in vector SIMD, 822 in the prime sieve and 175,015 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 560% above in integer math, 545% above in floating-point math, 574% above in compression, 614% above in cryptography, 790% above in physics simulation, 654% above in vector SIMD, 1,127% above in the prime sieve and 673% 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 6740P has 48 physical cores and runs 96 logical threads. It runs 2 threads per core. It runs at a base clock of 2.10 GHz and boosts up to 3.80 GHz.

The Intel Xeon 6740P 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 6740P has 5.25 MB of L1 cache, 96 MB of L2 cache and 288 MB of L3 cache. That adds up to about 389.3 MB of cache, or 8.11 MB per core. Each core has 2 MB of private L2 cache.

The Intel Xeon 6740P has a 3-level cache hierarchy: L1 at 5.3 MB, L2 at 96 MB and L3 at 288 MB. L3 is the largest level and makes up about 74% of the cache listed here.

The Intel Xeon 6740P 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 6740P does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon 6740P uses the FCLGA4710 socket, supports PCI Express 5.0 and provides up to 88 PCIe lanes.

The Intel Xeon 6740P has a rated TDP of 270 W.
