Intel® Xeon™ Silver 4509Y

The Intel Xeon Silver 4509Y is a server processor with 8 cores and 16 threads, built on the Sapphire Rapids architecture. It launched in Oct 2023. Clocks run from 2.6 GHz base to 4.1 GHz boost. A 22.5-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 (80 lanes). Rated TDP is 125 W. Notable platform capabilities: AMX, AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Xeon Silver 4509Y scores 2,139 in single-core performance and 18,337 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 6,263 for overall performance, 14,914 for productivity performance, 13,936 for creator performance, 18,795 for engineering performance and 11,001 for gaming performance. Its multi-core throughput works out to 2,292 per core, 1,146 per thread and 147 per watt. Its computed efficiency index is 560. Its performance index is 78, so its overall performance is 22% 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 Silver 4509Y scores 53,817 in integer math, 42,067 in floating-point math, 210,689 in compression, 10,634 in cryptography, 1,278 in physics simulation, 18,818 in vector SIMD, 107 in the prime sieve and 23,107 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 9% below in integer math, 8% below in floating-point math, 8% below in compression, 7% below in cryptography, 17% above in physics simulation, 21% above in vector SIMD, 60% above in the prime sieve and 2% 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 Silver 4509Y has 8 physical cores and runs 16 logical threads. It runs 2 threads per core. It runs at a base clock of 2.60 GHz and boosts up to 4.10 GHz.

The Intel Xeon Silver 4509Y is a server processor, belongs to the Intel Xeon Silver family, uses the Sapphire Rapids architecture and carries the codename Sapphire Rapids. It launched in Oct 2023.

The Intel Xeon Silver 4509Y has 640 KB of L1 cache, 16 MB of L2 cache and 22.5 MB of L3 cache. That adds up to about 39.1 MB of cache, or 4.89 MB per core. Each core has 2 MB of private L2 cache.

The Intel Xeon Silver 4509Y has a 3-level cache hierarchy: L1 at 640 KB, L2 at 16 MB and L3 at 22.5 MB. L3 is the largest level and makes up about 58% of the cache listed here.

The Intel Xeon Silver 4509Y 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 Silver 4509Y does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Silver 4509Y uses the FCLGA4677 socket, supports PCI Express 5.0 and provides up to 80 PCIe lanes.

The Intel Xeon Silver 4509Y has a rated TDP of 125 W.
