Intel® Xeon™ Gold 6430

The Intel Xeon Gold 6430 is a server processor with 32 cores and 64 threads, built on the Sapphire Rapids architecture. It launched in Jan 2023. Clocks run from 2.1 GHz base to 3.4 GHz boost. A 60-MB L3 cache backs the cores (4.0 MB per core). It addresses DDR5 memory up to 4 GB across 8 channels. The chip drops into the FCLGA4677 socket and exposes PCIe 5.0 (80 lanes). Rated TDP is 270 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon Gold 6430 scores 2,300 in single-core performance and 53,587 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 11,102 for overall performance, 38,052 for productivity performance, 33,613 for creator performance, 75,022 for engineering performance and 20,297 for gaming performance. Its multi-core throughput works out to 1,675 per core, 837 per thread and 199 per watt. Its computed efficiency index is 676. Its performance index is 138, so its overall performance is 38% 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 6430 scores 214,700 in integer math, 167,476 in floating-point math, 833,486 in compression, 42,004 in cryptography, 4,453 in physics simulation, 68,455 in vector SIMD, 319 in the prime sieve and 90,927 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 265% above in integer math, 265% above in floating-point math, 265% above in compression, 266% above in cryptography, 309% above in physics simulation, 341% above in vector SIMD, 376% above in the prime sieve and 301% 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 6430 has 32 physical cores and runs 64 logical threads. It runs 2 threads per core. It runs at a base clock of 2.10 GHz and boosts up to 3.40 GHz.

The Intel Xeon Gold 6430 is a server processor, belongs to the Intel Xeon Gold family, uses the Sapphire Rapids architecture and carries the codename Sapphire Rapids. It launched in Jan 2023.

The Intel Xeon Gold 6430 has 2.50 MB of L1 cache, 64 MB of L2 cache and 60 MB of L3 cache. That adds up to about 126.5 MB of cache, or 3.95 MB per core. Each core has 2 MB of private L2 cache.

The Intel Xeon Gold 6430 has a 3-level cache hierarchy: L1 at 2.5 MB, L2 at 64 MB and L3 at 60 MB. L2 is the largest level and makes up about 51% of the cache listed here.

The Intel Xeon Gold 6430 supports DDR5 memory, addresses up to 4 GB of memory and uses 8 memory channels. It does not support DDR4 and LPDDR memory.

The Intel Xeon Gold 6430 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Gold 6430 uses the FCLGA4677 socket, supports PCI Express 5.0 and provides up to 80 PCIe lanes.

The Intel Xeon Gold 6430 has a rated TDP of 270 W.
