Intel Core i5-9400F @ 2.90GHz + Radeon RX 7800 XT
Intel Core i5-9400F @ 2.90GHz
Radeon RX 7800 XT
The Intel Core i5-9400F @ 2.90GHz paired with the Radeon RX 7800 XT produces a 23.8% bottleneck. The CPU is the limit, so it finishes its share of each frame last and the other component waits. A gap this size is worth planning an upgrade around.
Estimated FPS at 1080p, high preset
Ranges, not exact figures: identical builds vary by roughly a quarter in real use depending on drivers, thermals and background load. Bars are scaled against the fastest title here, and each row states which component sets its ceiling.
Every title here is CPU-limited on this pairing.
Method: estimated from measured GPU baseline framerates and PassMark CPU scores, capped by whichever component limits first. Workload factors derived from the OpenML "fps-in-video-games" dataset (CC-BY, Sven Peeters).
Intel Core i5-9400F @ 2.90GHz and Radeon RX 7800 XT: FPS by game and resolution
High preset. Each cell is a range; the label marks which component sets the ceiling. Blank cells mean this pairing has no measured data for that combination, and nothing is estimated in.

How quality settings affect this build: Fortnite at 1080p
Dropping settings only helps while the GPU is the limit. Once the label reads CPU, lowering quality stops buying frames on this pairing.
Every preset here is CPU-limited, which is exactly why the bars barely move.
Bottleneck by resolution
Raising resolution shifts load from the CPU to the GPU, so the balance of this pairing changes with the display it drives. Note this measures imbalance, not speed: the lowest figure is usually the lowest resolution, which is not the one to play at. Read it alongside the limiting part.
On this chart a longer bar is worse: it measures imbalance, not speed.
