BOTTLENECK PAIR · GAMING · 1440P HEADLINE
AMD Ryzen 5 5500 + AMD Radeon RX 7800 XT
// VERDICT · 1440P GAMING
5% CPU-bound. The AMD Ryzen 5 5500 is holding back the AMD Radeon RX 7800 XT.
CPU limits 1440p performance — single-thread headroom is the constraint at this resolution.
TL;DRThe AMD Ryzen 5 5500 + AMD Radeon RX 7800 XT pairing is rated Grade A for 1440p gaming with a recommended 600W PSU. Resolution-by-resolution: 1080p: 9% CPU-bound, 1440p: 5% CPU-bound, 4K: 2% CPU-bound. CPU and GPU bottleneck verdicts depend on resolution — a pairing that is CPU-bound at 1080p is often perfectly balanced at 4K because the GPU does more work per frame as pixel count increases.

// WHAT THIS PAIRING MEANS FOR YOUR GAMING
Plain-English breakdown.
The AMD Ryzen 5 5500 + AMD Radeon RX 7800 XT pair is 5% CPU-limited at 1440p. Same pattern at 1080p and 4K. As a build, it grades high-end (A).
Expect around 317 FPS in League of Legends and ~114 in the more demanding Baldur's Gate 3 — both at 1440p with high or ultra presets. Resolution matters more than most calculators show — the same parts give different verdicts at 1080p, 1440p, and 4K because GPU work scales with pixel count while CPU work is roughly fixed per frame.
If you upgrade the cpu, the AMD Ryzen 5 5600 is the closest higher-tier option — see the swap recommendations below for the FPS lift. Plan on at least a 600W PSU — that includes headroom for transient spikes on the AMD Radeon RX 7800 XT.
