AMD Ryzen 9 3950X

AMD R9 3950X

The AMD Ryzen 9 3950X is a high-end desktop processor with 16 cores based on the Zen 2 architecture. At launch in November 2019 it is the fastest CPU of the Matisse series. The 3950X clocks from 3.5 GHz (base) up to 4.7 GHz (Turbo for a single core). All sixteen cores can reach up to 4.1 GHz.

Thanks to the 16 cores and 32 threads, the 3950X offers excellent application performance - if the number of cores can be used. Thanks to the relatively high Turbo, the single core performance is also situated in the high end. For games however, there are faster CPUs, like the Core i9-10900K.

The Ryzen 9 3950X is manufactured in 7nm (the four CCX-cluster with the cores) at TSMC and 12 nm (I/O die) at Globalfoundries. The TDP is rated at 250 Watt and therefore the CPU needs a very powerful cooling system.
