Intel® Xeon™ Gold 5120

The Intel Xeon Gold 5120 is a server processor with 14 cores and 28 threads, built on the Skylake architecture. It launched in Jul 2017. Clocks run from 2.2 GHz base to 3.2 GHz boost. A 19.25-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 105 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon Gold 5120 scores 1,756 in single-core performance and 18,243 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 5,660 for overall performance, 14,316 for productivity performance, 13,194 for creator performance, 20,409 for engineering performance and 9,829 for gaming performance. Its multi-core throughput works out to 1,303 per core, 652 per thread and 174 per watt. Its computed efficiency index is 552. Its performance index is 70, so its overall performance is 30% 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 5120 scores 64,955 in integer math, 40,068 in floating-point math, 288,024 in compression, 6,944 in cryptography, 1,252 in physics simulation, 17,689 in vector SIMD, 83 in the prime sieve and 36,156 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 10% above in integer math, 13% below in floating-point math, 26% above in compression, 40% below in cryptography, 15% above in physics simulation, 14% above in vector SIMD, 24% above in the prime sieve and 60% 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 5120 has 14 physical cores and runs 28 logical threads. It runs 2 threads per core. It runs at a base clock of 2.20 GHz and boosts up to 3.20 GHz.

The Intel Xeon Gold 5120 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 5120 has 896 KB of L1 cache, 14 MB of L2 cache and 19.3 MB of L3 cache. That adds up to about 34.1 MB of cache, or 2.44 MB per core. Each core has 1 MB of private L2 cache.

The Intel Xeon Gold 5120 has a 3-level cache hierarchy: L1 at 896 KB, L2 at 14 MB and L3 at 19.3 MB. L3 is the largest level and makes up about 56% of the cache listed here.

The Intel Xeon Gold 5120 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 5120 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Gold 5120 uses the FCLGA3647 socket, supports PCI Express 3.0 and provides up to 48 PCIe lanes.

The Intel Xeon Gold 5120 has a rated TDP of 105 W.
