Intel® Xeon™ Gold 6444Y

The Intel Xeon Gold 6444Y is a server processor with 16 cores and 32 threads, built on the Sapphire Rapids architecture. It launched in Jan 2023. Clocks run from 3.6 GHz base to 4.0 GHz boost. A 45-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 270 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon Gold 6444Y scores 3,282 in single-core performance and 49,303 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 12,721 for overall performance, 36,642 for productivity performance, 33,024 for creator performance, 56,698 for engineering performance and 22,172 for gaming performance. Its multi-core throughput works out to 3,081 per core, 1,541 per thread and 183 per watt. Its computed efficiency index is 774. Its performance index is 158, so its overall performance is 58% 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 6444Y scores 164,573 in integer math, 128,564 in floating-point math, 641,373 in compression, 32,292 in cryptography, 4,205 in physics simulation, 53,644 in vector SIMD, 270 in the prime sieve and 65,699 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 179% above in integer math, 180% above in floating-point math, 181% above in compression, 181% above in cryptography, 286% above in physics simulation, 246% above in vector SIMD, 303% above in the prime sieve and 190% 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 6444Y has 16 physical cores and runs 32 logical threads. It runs 2 threads per core. It runs at a base clock of 3.60 GHz and boosts up to 4.00 GHz.

The Intel Xeon Gold 6444Y 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 6444Y has 1.25 MB of L1 cache, 32 MB of L2 cache and 45 MB of L3 cache. That adds up to about 78.3 MB of cache, or 4.89 MB per core. Each core has 2 MB of private L2 cache.

The Intel Xeon Gold 6444Y has a 3-level cache hierarchy: L1 at 1.3 MB, L2 at 32 MB and L3 at 45 MB. L3 is the largest level and makes up about 58% of the cache listed here.

The Intel Xeon Gold 6444Y 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 6444Y does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Gold 6444Y uses the FCLGA4677 socket, supports PCI Express 5.0 and provides up to 80 PCIe lanes.

The Intel Xeon Gold 6444Y has a rated TDP of 270 W.
