The AMD Ryzen Threadripper PRO 9965WX gives professionals 24 Zen 5 cores and 48 threads with a high 4.2GHz base clock and boost up to 5.4GHz - a strong balance of multi-threaded throughput and per-core responsiveness for CAD, simulation, and video production work. Its 128MB L3 cache and 8-channel ECC DDR5 memory support on WRX90 motherboards give it enterprise-grade memory bandwidth and reliability. A mid-tier entry in the PRO WX-series lineup, well suited to workstations that don't need the highest core counts but still benefit from ECC memory and 128 PCIe 5.0 lanes. No cooler is included.
