Intel® Xeon™ w5-3435X

The Intel Xeon w5-3435X is a workstation processor with 16 cores and 32 threads, built on the Sapphire Rapids architecture. It launched in Jan 2023. Clocks run from 3.1 GHz base to 4.7 GHz boost. A 45-MB L3 cache backs the cores (4.9 MB per core). It addresses DDR5 memory up to 4 GB across 8 channels. The chip drops into the FCLGA4677 socket and exposes PCIe 5.0 (112 lanes). Rated TDP is 270 W. Notable platform capabilities: AMX, AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Xeon w5-3435X scores 3,306 in single-core performance and 44,575 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 12,139 for overall performance, 33,602 for productivity performance, 30,467 for creator performance, 51,261 for engineering performance and 21,062 for gaming performance. Its multi-core throughput works out to 2,786 per core, 1,393 per thread and 165 per watt. Its computed efficiency index is 739. Its performance index is 150, so its overall performance is 50% 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 w5-3435X scores 148,512 in integer math, 115,457 in floating-point math, 575,497 in compression, 28,992 in cryptography, 3,309 in physics simulation, 47,495 in vector SIMD, 229 in the prime sieve and 58,054 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 152% above in integer math, 152% above in floating-point math, 152% above in compression, 152% above in cryptography, 204% above in physics simulation, 206% above in vector SIMD, 242% above in the prime sieve and 156% 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 w5-3435X has 16 physical cores and runs 32 logical threads. It does not use a hybrid performance and efficiency core layout. It runs 2 threads per core. It runs at a base clock of 3.10 GHz and boosts up to 4.70 GHz.

The Intel Xeon w5-3435X is a workstation processor, belongs to the Intel Xeon W family, uses the Sapphire Rapids architecture and carries the codename Sapphire Rapids. It launched in Jan 2023.

The Intel Xeon w5-3435X has 1.25 MB of L1 cache, 32 MB of L2 cache and 45 MB of L3 cache. That adds up to about 78.3 MB of cache, or 4.89 MB per core. Each core has 2 MB of private L2 cache.

The Intel Xeon w5-3435X has a 3-level cache hierarchy: L1 at 1.3 MB, L2 at 32 MB and L3 at 45 MB. L3 is the largest level and makes up about 58% of the cache listed here.

The Intel Xeon w5-3435X 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 w5-3435X does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon w5-3435X uses the FCLGA4677 socket, supports PCI Express 5.0 and provides up to 112 PCIe lanes.

The Intel Xeon w5-3435X has a rated TDP of 270 W.
