Downfall

The Intel Core Ultra 5 235 and AMD Radeon RX 6800 XT combination delivers a highly capable 1440p experience in Downfall, with the data showing a clear performance ceiling at 1080p where the CPU begins to limit frame rates. The measured results indicate that this pairing is best suited for high-refresh-rate 1440p gaming, offering a substantial performance uplift over 4K while maintaining excellent visual fidelity.

Resolution Scaling

The frame rate scaling across resolutions reveals a classic GPU-bound curve that transitions into a CPU-bound plateau at 1080p. At Ultra settings, the average frame rate drops from 122 FPS at 1920x1080 to 87 FPS at 2560x1440, a 29% reduction, and then further to 54 FPS at 3840x2160, a 38% reduction from 1440p. This steep decline at 4K clearly indicates that the graphics card is the limiting factor at higher resolutions, with the RX 6800 XT's 16 GB of GDDR6 memory and 512.0 GB/s bandwidth being taxed heavily by the increased pixel count.

The scaling pattern shifts dramatically when examining Low settings. At 1920x1080, the average frame rate reaches 291 FPS, but this drops to 207 FPS at 2560x1440 and 129 FPS at 3840x2160. The relatively smaller absolute drop from 1080p to 1440p (84 FPS) compared to the drop from 1440p to 4K (78 FPS) suggests that the CPU's 14 cores and 14 threads are keeping pace adequately at lower resolutions, but the GPU's rendering workload becomes the primary bottleneck as resolution increases.

Medium settings provide the most complete dataset, including minimum and maximum frame rates. At 1080p, the average is 238 FPS with a minimum of 202 FPS and maximum of 273 FPS. The 1440p Medium results show an average of 170 FPS with a minimum of 144 FPS and maximum of 195 FPS. At 4K Medium, the average drops to 106 FPS with a minimum of 90 FPS and maximum of 121 FPS. The consistent minimum frame rates across these resolutions indicate that the combination maintains stable performance without severe stuttering, though the 4K minimum of 90 FPS approaches the threshold where some users might notice frame pacing issues.

The data suggests that the limiting component shifts based on resolution. At 1080p, the Core Ultra 5 235's boost clock of 5.00 GHz and single-thread performance appear to be the constraining factor, as the GPU has ample headroom to render frames faster than the CPU can feed it. At 4K, the RX 6800 XT's raw compute capabilities—20.74 TFLOPS FP32 and 288.0 GPixel/s pixel rate—are fully utilized, making it the definitive bottleneck with frame rates roughly half of what is achievable at 1080p.
