Intel® Xeon™ Gold 6434

The Intel Xeon Gold 6434 is a server processor with 8 cores and 16 threads, built on the Sapphire Rapids architecture. It launched in Jan 2023. Clocks run from 3.7 GHz base to 4.1 GHz boost. A 22.5-MB L3 cache backs the cores (4.9 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 195 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon Gold 6434 scores 3,228 in single-core performance and 28,012 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 9,509 for overall performance, 22,727 for productivity performance, 21,217 for creator performance, 28,712 for engineering performance and 16,687 for gaming performance. Its multi-core throughput works out to 3,502 per core, 1,751 per thread and 144 per watt. Its computed efficiency index is 681. Its performance index is 118, so its overall performance is 18% 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 6434 scores 82,255 in integer math, 78,367 in floating-point math, 333,214 in compression, 13,480 in cryptography, 2,490 in physics simulation, 30,953 in vector SIMD, 195 in the prime sieve and 39,224 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 40% above in integer math, 71% above in floating-point math, 46% above in compression, 17% above in cryptography, 128% above in physics simulation, 100% above in vector SIMD, 191% above in the prime sieve and 73% 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 6434 has 8 physical cores and runs 16 logical threads. It runs 2 threads per core. It runs at a base clock of 3.70 GHz and boosts up to 4.10 GHz.

The Intel Xeon Gold 6434 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 6434 has 640 KB of L1 cache, 16 MB of L2 cache and 22.5 MB of L3 cache. That adds up to about 39.1 MB of cache, or 4.89 MB per core. Each core has 2 MB of private L2 cache.

The Intel Xeon Gold 6434 has a 3-level cache hierarchy: L1 at 640 KB, L2 at 16 MB and L3 at 22.5 MB. L3 is the largest level and makes up about 58% of the cache listed here.

The Intel Xeon Gold 6434 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 6434 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Gold 6434 uses the FCLGA4677 socket, supports PCI Express 5.0 and provides up to 80 PCIe lanes.

The Intel Xeon Gold 6434 has a rated TDP of 195 W.
