BOTTLENECK PAIR · GAMING · 1440P HEADLINE
AMD Ryzen 7 5800X3D + AMD Radeon RX 6700 XT
// VERDICT · 1440P GAMING
16% GPU-bound. The AMD Radeon RX 6700 XT is holding back the AMD Ryzen 7 5800X3D.
GPU is the limiting factor at 1440p gaming. CPU has roughly 16% of headroom available.
TL;DRThe AMD Ryzen 7 5800X3D + AMD Radeon RX 6700 XT pairing is rated Grade B for 1440p gaming with a recommended 600W PSU. Resolution-by-resolution: 1080p: 12% GPU-bound, 1440p: 16% GPU-bound, 4K: 15% GPU-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 7 5800X3D + AMD Radeon RX 6700 XT pair is 16% GPU-limited at 1440p. Same pattern at 1080p and 4K. As a build, it grades solid mid-range (B).
Expect around 232 FPS in League of Legends and ~77 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 gpu, the NVIDIA GeForce RTX 3060 Ti 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 6700 XT.
