Intel® Xeon™ Gold 5115

The Intel Xeon Gold 5115 is a server processor with 10 cores and 20 threads, built on the Skylake architecture. It launched in Jul 2017. Clocks run from 2.4 GHz base to 3.2 GHz boost. A 13.75-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 85 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon Gold 5115 scores 1,866 in single-core performance and 15,152 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 5,317 for overall performance, 12,461 for productivity performance, 11,692 for creator performance, 16,004 for engineering performance and 9,386 for gaming performance. Its multi-core throughput works out to 1,515 per core, 758 per thread and 178 per watt. Its computed efficiency index is 577. Its performance index is 66, so its overall performance is 34% 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 Gold 5115 scores 51,117 in integer math, 30,404 in floating-point math, 224,279 in compression, 5,920 in cryptography, 1,153 in physics simulation, 12,646 in vector SIMD, 71 in the prime sieve and 28,895 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 13% below in integer math, 34% below in floating-point math, 2% below in compression, 48% below in cryptography, 6% above in physics simulation, 18% below in vector SIMD, 6% above in the prime sieve and 28% 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 Gold 5115 has 10 physical cores and runs 20 logical threads. It runs 2 threads per core. It runs at a base clock of 2.40 GHz and boosts up to 3.20 GHz.

The Intel Xeon Gold 5115 is a server processor, belongs to the Intel Xeon Gold 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 Gold 5115 has 512 KB of L1 cache, 10 MB of L2 cache and 13.8 MB of L3 cache. That adds up to about 24.3 MB of cache, or 2.42 MB per core.

The Intel Xeon Gold 5115 has a 3-level cache hierarchy: L1 at 512 KB, L2 at 10 MB and L3 at 13.8 MB. L3 is the largest level and makes up about 57% of the cache listed here.

The Intel Xeon Gold 5115 supports DDR4 memory, addresses up to 768 GB of memory, uses 6 memory channels, runs memory at up to 2,400 MT/s and delivers up to 115.2 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The Intel Xeon Gold 5115 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Gold 5115 uses the FCLGA3647 socket, supports PCI Express 3.0 and provides up to 48 PCIe lanes.

The Intel Xeon Gold 5115 has a rated TDP of 85 W.
