AMD® Ryzen™ Threadripper 9960X

The AMD Ryzen Threadripper 9960X is a desktop processor with 24 cores and 48 threads, built on the Zen 5 architecture (4FFX process). It launched in 2025. Clocks run from 4.2 GHz base to 5.4 GHz boost. A 128-MB L3 cache backs the cores (6.4 MB per core). It addresses DDR5 memory up to 1024 GB across 4 channels. The chip drops into the sTR5 socket and exposes PCIe 5.0 (92 lanes). Rated TDP is 350 W. Notable platform capabilities: AVX-512, AVX-VNNI, AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen Threadripper 9960X scores 4,575 in single-core performance and 92,632 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 20,586 for overall performance, 66,616 for productivity performance, 59,183 for creator performance, 118,106 for engineering performance and 36,883 for gaming performance. Its multi-core throughput works out to 3,860 per core, 1,930 per thread and 265 per watt. Its computed efficiency index is 1,100. Its performance index is 255, so its overall performance is 155% 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 9960X scores 349,483 in integer math, 234,903 in floating-point math, 1,374,597 in compression, 65,814 in cryptography, 6,196 in physics simulation, 112,381 in vector SIMD, 753 in the prime sieve and 148,757 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 493% above in integer math, 412% above in floating-point math, 503% above in compression, 473% above in cryptography, 468% above in physics simulation, 625% above in vector SIMD, 1,024% above in the prime sieve and 557% 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 9960X has 24 physical cores and runs 48 logical threads. It runs 2 threads per core. It runs at a base clock of 4.20 GHz and boosts up to 5.40 GHz. Its clock multiplier is unlocked for overclocking.

The AMD Ryzen Threadripper 9960X is a desktop processor, belongs to the AMD Threadripper family, uses the Zen 5 architecture, carries the codename Shimada Peak and is manufactured on a 4FFX process. It launched in 2025.

The AMD Ryzen Threadripper 9960X has 1.88 MB of L1 cache, 24 MB of L2 cache and 128 MB of L3 cache. That adds up to about 153.9 MB of cache, or 6.41 MB per core. Each core has 1 MB of private L2 cache.

The AMD Ryzen Threadripper 9960X has a 3-level cache hierarchy: L1 at 1.9 MB, L2 at 24 MB and L3 at 128 MB. L3 is the largest level and makes up about 83% of the cache listed here.

The AMD Ryzen Threadripper 9960X supports DDR5 memory, addresses up to 1,024 GB of memory, uses 4 memory channels and runs memory at up to 6,400 MT/s. It does not support DDR4 and LPDDR memory.

The AMD Ryzen Threadripper 9960X does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD Ryzen Threadripper 9960X uses the sTR5 socket, supports PCI Express 5.0 and provides up to 92 PCIe lanes.

The AMD Ryzen Threadripper 9960X has a rated TDP of 350 W.
