Intel® Xeon™ Gold 6346

The Intel Xeon Gold 6346 is a server processor with 16 cores and 32 threads, built on the Ice Lake architecture. It launched in Apr 2021. Clocks run from 3.1 GHz base to 3.6 GHz boost. A 36-MB L3 cache backs the cores (3.6 MB per core). It addresses DDR4 memory up to 6 GB across 8 channels. The chip drops into the FCLGA4189 socket and exposes PCIe 4.0 (64 lanes). Rated TDP is 205 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon Gold 6346 scores 2,508 in single-core performance and 37,260 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 9,667 for overall performance, 27,730 for productivity performance, 25,007 for creator performance, 42,849 for engineering performance and 16,839 for gaming performance. Its multi-core throughput works out to 2,329 per core, 1,164 per thread and 182 per watt. Its computed efficiency index is 675. Its performance index is 120, so its overall performance is 20% above 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 6346 scores 133,561 in integer math, 79,114 in floating-point math, 479,397 in compression, 25,560 in cryptography, 2,827 in physics simulation, 38,007 in vector SIMD, 182 in the prime sieve and 60,864 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 127% above in integer math, 72% above in floating-point math, 110% above in compression, 122% above in cryptography, 159% above in physics simulation, 145% above in vector SIMD, 172% above in the prime sieve and 169% 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 6346 has 16 physical cores and runs 32 logical threads. It runs 2 threads per core. It runs at a base clock of 3.10 GHz and boosts up to 3.60 GHz.

The Intel Xeon Gold 6346 is a server processor, belongs to the Intel Xeon Gold family, uses the Ice Lake architecture, carries the codename Ice Lake and is manufactured on a 10 nm process. It launched in Apr 2021.

The Intel Xeon Gold 6346 has 960 KB of L1 cache, 20 MB of L2 cache and 36 MB of L3 cache. That adds up to about 56.9 MB of cache, or 3.56 MB per core.

The Intel Xeon Gold 6346 has a 3-level cache hierarchy: L1 at 960 KB, L2 at 20 MB and L3 at 36 MB. L3 is the largest level and makes up about 63% of the cache listed here.

The Intel Xeon Gold 6346 supports DDR4 memory, addresses up to 6 GB of memory, uses 8 memory channels, runs memory at up to 3,200 MT/s and delivers up to 204.8 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The Intel Xeon Gold 6346 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Gold 6346 uses the FCLGA4189 socket, supports PCI Express 4.0 and provides up to 64 PCIe lanes.

The Intel Xeon Gold 6346 has a rated TDP of 205 W.
