Doom

The pairing of the Intel Core i5-13400F with the AMD Radeon RX 6800 XT delivers a formidable 1080p and 1440p experience in Doom, with the data indicating the GPU becomes the primary limiting factor only when pushing towards 4K. The benchmark results show a clear hierarchy where the combination of a 10-core Raptor Lake processor and a 16 GB RDNA 2 graphics card produces frame rates that range from highly competitive at high refresh rates to merely playable at maximum resolution.

Resolution Scaling

The measured FPS data reveals a predictable decline in performance as resolution increases, but the rate of that decline tells a story about system balance. At 1080p with Ultra settings, the combo produces an average of 173.2 FPS. Moving to 1440p drops that figure to 111.3 FPS, a reduction of approximately 36%. Pushing further to 4K Ultra yields 62.3 FPS, which is another 44% decrease from the 1440p result. This steep fall-off indicates that while the CPU is strong enough to feed the GPU at lower resolutions, the RX 6800 XT's compute resources are being saturated as pixel count rises.

The scaling pattern shifts when examining lower presets. At Low settings, the jump from 1080p (292.9 FPS) to 1440p (190.4 FPS) represents a 35% loss, but the transition from 1440p to 4K (101.8 FPS) shows a 47% drop. This larger relative decline at 4K Low suggests that even with reduced graphical load, the GPU's memory bandwidth and shading units become the bottleneck. The RX 6800 XT, with its 512.0 GB/s bandwidth and 4608 shading units, is clearly the component being stressed at 4K, while the i5-13400F’s 20 MB of shared L3 cache and 4.60 GHz boost clock maintain sufficient headroom.

A more nuanced view emerges when comparing the 1080p to 4K scaling across presets. For High settings, the drop from 212.4 FPS to 74.5 FPS is a 65% reduction. For Medium settings, the fall from 251.8 FPS to 88 FPS is also 65%. This consistency across High and Medium presets indicates that the rendering pipeline is being scaled uniformly, with the GPU's 20.74 TFLOPS FP32 performance being the limiting factor. The fact that Low settings still see a 65% reduction (292.9 to 101.8 FPS) reinforces that the RX 6800 XT is the constraint, as even minimal graphical work cannot overcome the resolution-driven pixel throughput demands.

Settings Recommendations

The data suggests that the optimal experience for this combination depends heavily on the target display. For 4K displays, the High preset at 74.5 FPS provides a smooth experience that stays above the 60 FPS threshold, while Ultra at 62.3 FPS is marginally playable but leaves little room for frame-time spikes. The Medium preset at 88 FPS offers the best balance for 4K, delivering a 18% improvement over High while maintaining visual fidelity that is likely indistinguishable in fast-paced action.

At 1440p, the High preset at 140 FPS is the standout choice, as it clears the 120 Hz refresh rate mark with room to spare. The Medium preset at 167.1 FPS is even smoother, but the jump from Medium to High only costs 27 FPS, making High the more visually pleasing option without sacrificing playability. The Ultra preset at 111.3 FPS is still entirely viable for 1440p, but it falls short of the 144 Hz threshold that many users target, so High is the recommended middle ground.

For 1080p, the Ultra preset at 173.2 FPS is the clear winner, as it comfortably exceeds 165 Hz refresh rates and provides the maximum visual quality the game offers. The Low preset at 292.9 FPS is only relevant for competitive play on 240 Hz panels, but the graphical compromise is substantial. The data indicates that the i5-13400F does not bottleneck the RX 6800 XT at 1080p, as the 212.4 FPS High result shows the GPU is still the primary driver of performance.

FAQ

*Q: Can this combo run Doom at 4K with maximum settings?*

A: The Ultra preset at 4K averages 62.3 FPS, which is technically playable but leaves minimal margin. The High preset at 74.5 FPS is a safer choice for 4K, as it provides a 20% performance buffer over Ultra.

Q: What is the best preset for 1440p gaming?

A: The High preset at 140 FPS is the optimal balance, as it exceeds 120 Hz refresh rates while offering better visual quality than the Medium preset at 167.1 FPS. The Ultra preset at 111.3 FPS is viable but may not satisfy users with 144 Hz displays.

Q: How does the CPU affect performance at 1080p?

A: The i5-13400F, with its 10 cores and 16 threads, provides sufficient processing power to avoid bottlenecking the RX 6800 XT. The 1080p Ultra result of 173.2 FPS demonstrates that the GPU is the limiting component, as the CPU's single-thread score of 960 in 3dmark and 3634 in passmark single-thread tests are adequate for this workload.

Q: Is there a large performance gap between Medium and High settings?

A: The difference varies by resolution. At 1080p, the gap is 39.4 FPS (251.8 to 212.4), representing a 16% drop. At 1440p, the gap is 27.1 FPS (167.1 to 140), a 16% drop. At 4K, the gap is 13.5 FPS (88 to 74.5), also a 15% drop, so the relative cost of High over Medium is consistent.

Q: What frame rate can I expect at 1080p with Low settings?

A: The Low preset at 1080p averages 292.9 FPS, which is the highest result in the dataset. This is 69% faster than the Ultra preset, making it suitable for extreme refresh rate displays, though the visual quality is significantly reduced.

Q: How does this combo compare to other tested configurations?

A: The combination ranks 592nd out of 1681 tested combos, placing it in the top 35% of all pairings. This rank reflects the strong performance of the RX 6800 XT, which sits in the 87th percentile of all GPUs, paired with a CPU in the 82nd percentile.

Measured FPS Breakdown

At 1920x1080, the frame rates are consistently high across all presets. The Low setting produces an average of 292.9 FPS, followed by Medium at 251.8 FPS, High at 212.4 FPS, and Ultra at 173.2 FPS. The spread from lowest to highest preset is 119.7 FPS, showing that graphical settings have a substantial impact at this resolution, but even the most demanding preset clears the 144 Hz threshold.

At 2560x1440, the results show a similar pattern with reduced absolute numbers. Low averages 190.4 FPS, Medium drops to 167.1 FPS, High settles at 140 FPS, and Ultra bottoms out at 111.3 FPS. The gap between Low and Ultra is 79.1 FPS, which is proportionally similar to 1080p, confirming that the GPU scales predictably with resolution.

At 3840x2160, the performance curve becomes steeper. Low averages 101.8 FPS, Medium reaches 88 FPS, High manages 74.5 FPS, and Ultra falls to 62.3 FPS. The difference between Low and Ultra is 39.5 FPS, and notably, the Ultra preset barely stays above 60 FPS. This resolution is where the RX 6800 XT’s 16 GB of GDDR6 memory and 288 TMUs are taxed, as the pixel rate of 288.0 GPixel/s is insufficient to maintain higher frame rates at maximum settings.

How This Combo Ranks

The combo holds the 592nd position out of 1681 tested combinations, which puts it in the 65th percentile of all pairings. This ranking is driven primarily by the GPU’s strength, as the RX 6800 XT’s average benchmark score of 49982 places it in the 87th percentile among all GPUs. The nearest rivals in the GPU benchmark data include the Intel Arc A550M at 49737 (a 0.5% delta) and the NVIDIA RTX A1000 at 50826 (a -1.7% delta), showing that the RX 6800 XT is closely matched with these alternatives despite different architectures.

The CPU contributes positively to the ranking as well. The i5-13400F’s average benchmark score of 25236 places it in the 82nd percentile of all CPUs, with its nearest rival being the Intel Core i7-13620H at 25201 (a 0.1% delta). This near-identical score indicates that the i5-13400F is performing at the expected level for its class, with the AMD Ryzen 5 5600X3D at 25365 showing a -0.5% delta, meaning the i5-13400F is slightly behind that chip.

The combination’s rank of 592 suggests that there are many configurations that outperform it, but the data shows this pairing is well above the median. The 1080p Ultra result of 173.2 FPS and 1440p High result of 140 FPS are strong indicators that this combo is well-suited for high-refresh-rate gaming, while the 4K results are respectable for a GPU in the 87th percentile. The measured FPS data confirms the ranking is justified, as the system delivers competitive performance across all tested resolutions and settings.
