Intel® Xeon™ Silver 4109T

The Intel Xeon Silver 4109T is a server processor with 8 cores and 16 threads, built on the Skylake architecture. It launched in Jul 2017. Clocks run from 2.0 GHz base to 3.0 GHz boost. A 11-MB L3 cache backs the cores (2.4 MB per core). It addresses DDR4 memory up to 768 GB across 6 channels. The chip drops into the FCLGA3647 socket and exposes PCIe 3.0 (48 lanes). Rated TDP is 70 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon Silver 4109T scores 1,671 in single-core performance and 10,378 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 4,164 for overall performance, 9,085 for productivity performance, 8,716 for creator performance, 10,637 for engineering performance and 7,608 for gaming performance. Its multi-core throughput works out to 1,297 per core, 649 per thread and 148 per watt. Its computed efficiency index is 498. Its performance index is 52, so its overall performance is 48% 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 4109T scores 33,562 in integer math, 20,579 in floating-point math, 146,737 in compression, 3,635 in cryptography, 727 in physics simulation, 9,185 in vector SIMD, 49 in the prime sieve and 18,654 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 43% below in integer math, 55% below in floating-point math, 36% below in compression, 68% below in cryptography, 33% below in physics simulation, 41% below in vector SIMD, 27% below in the prime sieve and 18% 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 Silver 4109T has 8 physical cores and runs 16 logical threads. It runs 2 threads per core. It runs at a base clock of 2.00 GHz and boosts up to 3.00 GHz.

The Intel Xeon Silver 4109T is a server processor, belongs to the Intel Xeon Silver family, uses the Skylake architecture, carries the codename Skylake and is manufactured on a 14 nm process. It launched in Jul 2017.

The Intel Xeon Silver 4109T has 256 KB of L1 cache, 8 MB of L2 cache and 11 MB of L3 cache. That adds up to about 19.3 MB of cache, or 2.41 MB per core.

The Intel Xeon Silver 4109T has a 3-level cache hierarchy: L1 at 256 KB, L2 at 8 MB and L3 at 11 MB. L3 is the largest level and makes up about 57% of the cache listed here.

The Intel Xeon Silver 4109T supports DDR4 memory, addresses up to 768 GB of memory and uses 6 memory channels. It does not support DDR5 and LPDDR memory.

The Intel Xeon Silver 4109T does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Silver 4109T uses the FCLGA3647 socket, supports PCI Express 3.0 and provides up to 48 PCIe lanes.

The Intel Xeon Silver 4109T has a rated TDP of 70 W.
