The Ryzen 7 5800X is the best CPU for the job, it’s efficient and powerful. Making it the perfect CPU for the RX 6800 XT. Especially during 4k gaming. As this CPU is capable of keeping up at higher resolutions.

The 5800X has very respectable 8-Cores and 16-Threads to work with, making it a monster in multi-core workloads. This CPU can really do it all. It has the cores and the thread count, in addition to the core speed to be viable in both single-core and multi-core workloads.

The gaming performance lends its hand to the 4.7GHz max core boost speed. As we all know, A CPUs max core speed can have a huge effect on how that CPU will perform in-game. Exactly why the faster core CPUs are preferred for gaming tasks.

The 5800X has a TDP of 105W, which is a lot higher than the lower-end Ryzen 5000 series CPUs, but it’s very efficient for the amount of power it consumes and the amount of processing power it provides.
