The AMD Ryzen Threadripper PRO 9955WX is the entry point into AMD's Zen 5 PRO workstation lineup, with 16 cores and 32 threads, a high 4.5GHz base clock, and boost up to 5.4GHz - strong for CAD, engineering, and content-creation applications that value both multi-threaded output and fast single-core response. Its 64MB L3 cache and 8-channel ECC DDR5 memory on WRX90 motherboards still give it a real advantage over consumer platforms for memory-bound professional software, along with 128 PCIe 5.0 lanes for multiple accelerators or storage devices. Ships without a cooler.
