AMD® Ryzen™ Threadripper 3960X

The AMD Ryzen Threadripper 3960X is a desktop processor with 24 cores and 48 threads, built on the Zen 2 architecture (7 nm process). It launched in Nov 2019. Clocks run from 3.8 GHz base to 4.5 GHz boost. A 128-MB L3 cache backs the cores (5.9 MB per core). It uses the sTRX4 socket. Rated TDP is 280 W. Notable platform capabilities: AVX-512, AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen Threadripper 3960X scores 2,681 in single-core performance and 54,742 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 12,115 for overall performance, 39,336 for productivity performance, 34,934 for creator performance, 69,796 for engineering performance and 21,729 for gaming performance. Its multi-core throughput works out to 2,281 per core, 1,140 per thread and 196 per watt. Its computed efficiency index is 724. Its performance index is 150, so its overall performance is 50% 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 3960X scores 198,847 in integer math, 116,684 in floating-point math, 894,631 in compression, 57,196 in cryptography, 3,301 in physics simulation, 57,793 in vector SIMD, 415 in the prime sieve and 94,478 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 238% above in integer math, 154% above in floating-point math, 292% above in compression, 398% above in cryptography, 203% above in physics simulation, 273% above in vector SIMD, 519% above in the prime sieve and 317% 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 3960X has 24 physical cores and runs 48 logical threads. It does not use a hybrid performance and efficiency core layout. It runs 2 threads per core. It runs at a base clock of 3.80 GHz and boosts up to 4.50 GHz.

The AMD Ryzen Threadripper 3960X is a desktop processor, belongs to the AMD Threadripper family, uses the Zen 2 architecture, carries the codename Castle Peak and is manufactured on a 7 nm process. It launched in Nov 2019.

The AMD Ryzen Threadripper 3960X has 1.50 MB of L1 cache, 12 MB of L2 cache and 128 MB of L3 cache. That adds up to about 141.5 MB of cache, or 5.90 MB per core. Each core has 512 KB of private L2 cache.

The AMD Ryzen Threadripper 3960X has a 3-level cache hierarchy: L1 at 1.5 MB, L2 at 12 MB and L3 at 128 MB. L3 is the largest level and makes up about 90% of the cache listed here.

The AMD Ryzen Threadripper 3960X does not include integrated graphics, so a discrete graphics card is required for display output.
