Intel® Xeon™ Gold 6148

The Intel Xeon Gold 6148 is a server processor with 20 cores and 40 threads, built on the Skylake architecture. It launched in Jul 2017. Clocks run from 2.4 GHz base to 3.7 GHz boost. A 27.5-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 150 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon Gold 6148 scores 2,068 in single-core performance and 28,093 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 7,622 for overall performance, 21,156 for productivity performance, 19,174 for creator performance, 34,063 for engineering performance and 13,227 for gaming performance. Its multi-core throughput works out to 1,405 per core, 702 per thread and 187 per watt. Its computed efficiency index is 622. Its performance index is 94, so its overall performance is 6% 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 6148 scores 111,754 in integer math, 68,524 in floating-point math, 481,201 in compression, 11,001 in cryptography, 1,761 in physics simulation, 34,550 in vector SIMD, 119 in the prime sieve and 60,328 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 90% above in integer math, 49% above in floating-point math, 111% above in compression, 4% below in cryptography, 62% above in physics simulation, 123% above in vector SIMD, 78% above in the prime sieve and 166% 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 6148 has 20 physical cores and runs 40 logical threads. It runs 2 threads per core. It runs at a base clock of 2.40 GHz and boosts up to 3.70 GHz.

The Intel Xeon Gold 6148 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 6148 has 1.25 MB of L1 cache, 20 MB of L2 cache and 27.5 MB of L3 cache. That adds up to about 48.8 MB of cache, or 2.44 MB per core. Each core has 1 MB of private L2 cache.

The Intel Xeon Gold 6148 has a 3-level cache hierarchy: L1 at 1.3 MB, L2 at 20 MB and L3 at 27.5 MB. L3 is the largest level and makes up about 56% of the cache listed here.

The Intel Xeon Gold 6148 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 Gold 6148 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Gold 6148 uses the FCLGA3647 socket, supports PCI Express 3.0 and provides up to 48 PCIe lanes.

The Intel Xeon Gold 6148 has a rated TDP of 150 W.
