AMD® Ryzen™ Threadripper PRO 3995WX

The AMD Ryzen Threadripper PRO 3995WX is a workstation processor with 64 cores and 128 threads, built on the Zen 2 architecture (7 nm process). It launched in 2020. Clocks run from 2.7 GHz base to 4.2 GHz boost. A 256-MB L3 cache backs the cores (4.6 MB per core). Maximum addressable memory is 2000 GB. It uses the sWRX8 socket. Rated TDP is 280 W. Notable platform capabilities: AVX-512, AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen Threadripper PRO 3995WX scores 2,590 in single-core performance and 82,556 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 14,623 for overall performance, 57,287 for productivity performance, 50,068 for creator performance, 115,578 for engineering performance and 28,409 for gaming performance. Its multi-core throughput works out to 1,290 per core, 645 per thread and 295 per watt. Its computed efficiency index is 874. Its performance index is 181, so its overall performance is 81% 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 AMD Ryzen Threadripper PRO 3995WX scores 487,160 in integer math, 276,283 in floating-point math, 1,832,047 in compression, 123,702 in cryptography, 5,168 in physics simulation, 105,817 in vector SIMD, 538 in the prime sieve and 184,253 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 727% above in integer math, 502% above in floating-point math, 703% above in compression, 977% above in cryptography, 374% above in physics simulation, 582% above in vector SIMD, 703% above in the prime sieve and 713% 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 AMD Ryzen Threadripper PRO 3995WX has 64 physical cores and runs 128 logical threads. It runs 2 threads per core. It runs at a base clock of 2.70 GHz and boosts up to 4.20 GHz. Its clock multiplier is locked, so it does not support multiplier overclocking.

The AMD Ryzen Threadripper PRO 3995WX is a workstation processor, belongs to the AMD Threadripper PRO family, uses the Zen 2 architecture, carries the codename Matisse and is manufactured on a 7 nm process. It launched in 2020.

The AMD Ryzen Threadripper PRO 3995WX has 4 MB of L1 cache, 32 MB of L2 cache and 256 MB of L3 cache. That adds up to about 292.0 MB of cache, or 4.56 MB per core. Each core has 512 KB of private L2 cache.

The AMD Ryzen Threadripper PRO 3995WX has a 3-level cache hierarchy: L1 at 4 MB, L2 at 32 MB and L3 at 256 MB. L3 is the largest level and makes up about 88% of the cache listed here.

The AMD Ryzen Threadripper PRO 3995WX addresses up to 2,000 GB of memory and runs memory at up to 3,200 MT/s.

The AMD Ryzen Threadripper PRO 3995WX does not include integrated graphics, so a discrete graphics card is required for display output.
