Best CPU to Pair with Radeon R9 380X
Pairing the right CPU with your Radeon R9 380X avoids leaving performance on the table — or wasting money on a chip your GPU can't fully use. These picks are ranked by gaming performance tier, not price.

Frequently Asked Questions
Will my CPU bottleneck the Radeon R9 380X?
At 1080p, a CPU below our Balanced pick (Ryzen 9 3950X) will likely cap frame rates before the Radeon R9 380X reaches its full potential. At 1440p and 4K, the GPU becomes the limiter for most chips.
What is the cheapest CPU that won't bottleneck a Radeon R9 380X?
Our Budget tier pick (Ryzen 7 2700) is the minimum gaming CPU we'd pair with a Radeon R9 380X without a severe 1080p bottleneck. Going cheaper saves money but costs fps in CPU-bound titles.
Do I need a flagship CPU for a Radeon R9 380X?
For most gamers, no — our Enthusiast pick (Ryzen Threadripper PRO 5945WX) is only worth it if you chase maximum 1080p high-refresh fps or stream while gaming. The Balanced tier is the sweet spot for most Radeon R9 380X builds.
