The AMD Athlon X4 870K paired with the Radeon RX 560 produces a 10.27% 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 usually recoverable through resolution and settings rather than new hardware.

Every build has a bottleneck; the question is only whether it sits where you want it. Read the figure alongside the limiting part, because the same percentage means different things at 1080p and at 4K.

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 GPU-limited on this pairing.

Fortnite 45-75FPS
CS:GO 73-122FPS
GTA V 27-45FPS
Apex Legends 29-48FPS
PUBG 29-49FPS

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).

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 GPU-limited, which is exactly why the bars barely move.

Low 57-95FPS
Medium 54-91FPS
High 45-75FPS
Max 32-53FPS

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.

Smallest imbalance 1280x720 9.8% bottleneck · CPU-limited
Largest imbalance 7680x4620 19.4% bottleneck · GPU-limited

On this chart a longer bar is worse: it measures imbalance, not speed.
