Core i7-9700K + Radeon RX 7900 GRE Bottleneck Calculator

Whether the Core i7-9700K and the Radeon RX 7900 GRE hold each other back, at every resolution, with the frame rate you can expect and the single upgrade that fixes it.

Estimates built from published benchmark data, not a test of your exact PC. How we calculate this.

  • The platform itself is a limit here: an older socket usually means PCIe 3.0 and slower memory, which costs a few percent on top of the figure above.

The same pair at every resolution

A processor pushes roughly the same number of frames whatever the resolution. A graphics card pushes far fewer as pixels go up. That is why the limit moves as you climb this table, and why a bottleneck figure quoted without a resolution means nothing.

What to do about it

The Ryzen 9 7900 is the slowest CPU in our database that stops the Radeon RX 7900 GRE from idling at 1080p (1920 x 1080). A faster chip than that adds nothing at this resolution, so this is the step to buy, not the top of the stack.
