AMD Ryzen 9 3900 vs AMD Ryzen 7 3800XT

AMD Ryzen 9 3900

► remove from comparison AMD R9 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.

AMD Ryzen 7 3800XT

► remove from comparison AMD R7 3800XT

The AMD Ryzen 7 3800XT is a fast desktop processor with 8 cores (octa core) based on the Zen 2 architecture. At launch it is the fastest 8-core-CPU of the Matisse series. The 3800XT clocks from 3.9 GHz (base) up to 4.7 GHz (Turbo). All eight cores can reach up to 4.2 GHz.

Performance

The average 3800XT in our database is in the same league as the Core i5-12500H, Core i5-13500H, Core i9-10910, Ryzen 7 5700G, Ryzen 7 7735HS, Ryzen 9 6900HS, Ryzen 9 6900HX, as far as multi-thread performance is concerned.

Power consumption

This Ryzen 7 series processor has a default TDP, also known as the long-term power limit, of 105 W. Needless to say, if one was to overclock it, the chip's power consumption would go up by a huge margin.

The R7 3800XT is built with TSMC's 7 nm process making for average, as of mid 2023, energy efficiency.
