Intel® Xeon™ Gold 6442Y

The Intel Xeon Gold 6442Y is a server processor with 24 cores and 48 threads, built on the Sapphire Rapids architecture. It launched in Jan 2023. Clocks run from 2.6 GHz base to 4.0 GHz boost. A 60-MB L3 cache backs the cores (4.6 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 225 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon Gold 6442Y scores 3,268 in single-core performance and 58,534 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 13,831 for overall performance, 42,622 for productivity performance, 38,076 for creator performance, 74,631 for engineering performance and 24,438 for gaming performance. Its multi-core throughput works out to 2,439 per core, 1,219 per thread and 260 per watt. Its computed efficiency index is 922. Its performance index is 171, so its overall performance is 71% 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 6442Y scores 206,148 in integer math, 157,829 in floating-point math, 785,693 in compression, 41,519 in cryptography, 5,546 in physics simulation, 64,415 in vector SIMD, 351 in the prime sieve and 82,978 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 250% above in integer math, 244% above in floating-point math, 245% above in compression, 261% above in cryptography, 409% above in physics simulation, 315% above in vector SIMD, 424% above in the prime sieve and 266% 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 6442Y has 24 physical cores and runs 48 logical threads. It runs 2 threads per core. It runs at a base clock of 2.60 GHz and boosts up to 4.00 GHz.

The Intel Xeon Gold 6442Y 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 6442Y has 1.88 MB of L1 cache, 48 MB of L2 cache and 60 MB of L3 cache. That adds up to about 109.9 MB of cache, or 4.58 MB per core. Each core has 2 MB of private L2 cache.

The Intel Xeon Gold 6442Y has a 3-level cache hierarchy: L1 at 1.9 MB, L2 at 48 MB and L3 at 60 MB. L3 is the largest level and makes up about 55% of the cache listed here.

The Intel Xeon Gold 6442Y 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 6442Y does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Gold 6442Y uses the FCLGA4677 socket, supports PCI Express 5.0 and provides up to 80 PCIe lanes.

The Intel Xeon Gold 6442Y has a rated TDP of 225 W.
