AMD Ryzen 9 3900

The Ryzen 9 3900 is a fast desktop CPU with 12 cores and 24 threads based on the Matisse series. It is the fastest 65 Watt CPU at launch in late 2019 and clocks the cores between 3.1 (base) to 4.3 (boost) clock (including Precision Boost). It uses 4 CCX-clusters where 3 of the 4 cores are activated. The CPU is manufactured in the modern 7nm process at TSMC. The I/O die on the package is separate and manufactured in 12 nm at Globalfoundries.

Due to the reduced Turbo speed, the Ryzen 9 3900 is aimed at content creators and other professionals that can make use of the 12 cores. For games, a fast 8-core CPU with higher boost clocks is the better choice.
