Intel® Xeon™ W3503

The Intel Xeon W3503 is a server processor with 2 cores and 2 threads, built on the Nehalem architecture. It launched in Mar 2009. A 4-MB L3 cache backs the cores (2.3 MB per core). It supports DDR3 memory. It uses the FCLGA1366 socket. Rated TDP is 130 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon W3503 scores 1,024 in single-core performance and 1,105 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,064 for overall performance, 2,152 for productivity performance, 2,451 for creator performance, 1,029 for engineering performance and 3,348 for gaming performance. Its multi-core throughput works out to 553 per core, 553 per thread and 9 per watt. Its computed efficiency index is 93. Its performance index is 13, so its overall performance is 87% below 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 W3503 scores 4,132 in integer math, 2,573 in floating-point math, 20,335 in compression, 227 in cryptography, 160 in physics simulation, 684 in vector SIMD, 11 in the prime sieve and 2,710 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 93% below in integer math, 94% below in floating-point math, 91% below in compression, 98% below in cryptography, 85% below in physics simulation, 96% below in vector SIMD, 84% below in the prime sieve and 88% below 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 W3503 has 2 physical cores and runs 2 logical threads. It does not use a hybrid performance and efficiency core layout. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 2.40 GHz.

The Intel Xeon W3503 is a server processor, belongs to the Intel Xeon W family and uses the Nehalem architecture. It launched in Mar 2009.

The Intel Xeon W3503 has 128 KB of L1 cache, 512 KB of L2 cache and 4 MB of L3 cache. That adds up to about 4.6 MB of cache, or 2.31 MB per core. Each core has 256 KB of private L2 cache.

The Intel Xeon W3503 has a 3-level cache hierarchy: L1 at 128 KB, L2 at 512 KB and L3 at 4 MB. L3 is the largest level and makes up about 86% of the cache listed here.

The Intel Xeon W3503 supports DDR3 memory and runs memory at up to 1,066 MT/s. It does not support DDR5, DDR4 and LPDDR memory.

The Intel Xeon W3503 uses the FCLGA1366 socket.

The Intel Xeon W3503 has a rated TDP of 130 W.
