AMD Threadripper Pro 9995WX 5.4GHz Socket STR5 Boxed

Cores and performance

• 96 Zen 5 cores and 192 SMT threads, base frequency of 2.5 GHz and maximum boost up to 5.4 GHz, with unlocked multiplier for extreme overclocking.

• Huge cache: 64 KB L1 per core, 1 MB L2 per core, 384 MB L3 shared (total ~480 MB), optimising latencies in massively parallel workloads.

• ~16% higher IPC than Zen 4, outperforming Threadripper PRO 7995WX by ~22% multicore and up to 2.2x vs Intel Xeon W9-3595X in Cinebench/V-Ray.

Platform and connectivity

• Socket sTR5 (SP6) for WRX90 boards, with 128 PCIe 5.0 lanes (136 total) for multi-GPU (RTX 5090 x8+), massive RAID Gen5 and 200Gbe networking.

• Octa-channel DDR5-6400 ECC memory up to 2TB RDIMM (OC 8000+ MT/s), with AMD EXPO and Registered ECC for 24/7 critical stability.

• 6nm die I/O with PRO Manageability (DASH, Memory Guard), Secure Encrypted Virtualization and native AVX-512/bfloat16 for AI.

Efficiency and thermal

• TDP 350 W (peak >500W all-core), custom heavy-duty cooling required (AIO 560mm+, direct-die loop); manufactured on TSMC 4nm (CCD) + 6nm (IOD), 99.78 billion transistors.

• Tjmax 95°C, 12x CCDs of 70.6 mm² each; ~20% higher efficiency than Zen 4 at sustained loads.
