Doom

This PC configuration pairs the AMD Ryzen 5 8400F with the NVIDIA GeForce RTX 5080 for playing Doom. The measured data shows a system that delivers exceptionally high frame rates across all tested resolutions and presets, with the RTX 5080 providing the dominant performance headroom. The following analysis breaks down the benchmark results, ranking, component roles, and practical settings for this specific game.

Measured FPS Breakdown

The benchmark data for Doom reveals a clear performance hierarchy across three resolutions and four quality presets. At 1920x1080, the combo achieves its highest raw frame rates, starting with 387 FPS on Low settings. Moving up to Medium yields 366.6 FPS, while High settings produce 313.7 FPS. The most demanding Ultra preset still delivers 258.3 FPS, which is more than four times the playable threshold of 60 FPS. These numbers indicate that at 1080p, the RTX 5080 is operating well below its ceiling, with the CPU likely becoming a more significant factor at the very highest frame rates.

At 2560x1440, the frame rates remain extraordinarily high but show a noticeable step down from 1080p. Low settings produce 272.8 FPS, Medium delivers 237.5 FPS, and High settings reach 200.7 FPS. The Ultra preset still maintains 162.7 FPS, which is comfortably above 60 FPS and even above 144 FPS for high refresh rate monitors. The scaling from Low to Ultra at this resolution shows a performance drop of roughly 40%, from 272.8 FPS down to 162.7 FPS, which demonstrates that the GPU is beginning to feel the load of higher resolution rendering.

At 3840x2160, the performance impact of 4K resolution becomes more pronounced. Low settings deliver 151.8 FPS, Medium drops to 129.1 FPS, and High settings produce 109.1 FPS. The Ultra preset still achieves 91 FPS, which remains well above the 60 FPS playable threshold. The gap between Low and Ultra at 4K is about 40%, similar to the 1440p scaling, but the absolute numbers are roughly 45% lower across the board compared to 1440p. This resolution scaling suggests the GPU is the primary bottleneck at 4K, as the frame rate drops are consistent with the increased pixel count.

The data lacks min and max FPS values, so the analysis relies solely on average frame rates. However, the consistency of the averages across presets and resolutions indicates stable performance characteristics. The RTX 5080 appears to handle Doom's engine with substantial headroom even at 4K Ultra, where the 91 FPS average leaves room for demanding scenes or background tasks without dropping below playable levels.

How This Combo Ranks

The combined rank for this CPU and GPU pairing in Doom is 172 out of 3712 tested combinations. This places the configuration in the top 4.6% of all tested systems, which aligns with the high performance levels seen in the FPS measurements. The rank reflects the RTX 5080's strong showing in the game's benchmark, as the GPU's percentile versus all GPUs is 87, meaning it outperforms 87% of tested graphics cards. The CPU's percentile versus all CPUs is 77, which is lower but still above average.

The combo rank of 172 suggests that while the RTX 5080 is a top-tier GPU, the Ryzen 5 8400F does not fully maximize its potential. The CPU's single-thread benchmark score of 951 in 3DMark and multi-thread score of 6165 indicate solid performance, but the GPU is clearly the stronger component in this pairing. The rank of 172 out of 3712 means there are 171 tested combinations that achieve higher performance in Doom, likely featuring higher-end CPUs paired with equally powerful or stronger GPUs.

The percentile data reinforces this interpretation. The GPU sits at the 87th percentile, while the CPU sits at the 77th percentile. This 10-point gap suggests that in many of the 171 higher-ranked combos, the CPU is more capable, allowing the GPU to reach even higher frame rates. However, for practical purposes, the combo rank of 172 is still excellent, and the measured FPS data shows that this configuration exceeds 60 FPS at every resolution and preset tested.

CPU and GPU Roles

The data reveals a clear division of labor between the Ryzen 5 8400F and the RTX 5080 in Doom. At 1920x1080, the frame rates are so high (258-387 FPS) that the CPU's performance becomes a limiting factor. The scaling from Low to Ultra at 1080p shows a 33% drop in FPS (from 387 to 258.3), but the absolute numbers suggest the CPU is working hard to feed the GPU. The Ryzen 5 8400F has 6 cores and 12 threads with a boost clock of 4.70 GHz, which is adequate for high-FPS gaming, but the 387 FPS Low setting result points to the CPU's ceiling being reached.

At 2560x1440, the GPU begins to take on more responsibility. The frame rates drop from 272.8 FPS on Low to 162.7 FPS on Ultra, a 40% reduction. This larger percentage drop compared to 1080p indicates the GPU is becoming the primary bottleneck, as the increased pixel count requires more graphics processing power. The CPU still has enough headroom at these frame rates, as even the Low preset result of 272.8 FPS suggests the processor can keep up with the GPU's output.

At 3840x2160, the GPU's role becomes dominant. The frame rates range from 151.8 FPS on Low to 91 FPS on Ultra, and the scaling between presets is consistent with pure GPU-bound performance. The CPU's role diminishes further, as the frame rates are lower and the processor has more time to prepare frames. The 91 FPS Ultra result at 4K demonstrates that the RTX 5080 is the limiting factor, as the CPU would need to be significantly weaker to affect performance at this resolution.

The cross-resolution scaling reinforces this analysis. Moving from 1080p Ultra to 1440p Ultra results in a 37% FPS drop (from 258.3 to 162.7), while moving from 1440p Ultra to 4K Ultra results in a 44% drop (from 162.7 to 91). This increasing percentage drop as resolution rises is a classic sign of GPU-bound performance scaling, confirming that the RTX 5080 is the dominant component at higher resolutions.

Similar Performance Alternatives

The nearest rivals for the Ryzen 5 8400F provide context for CPU performance. The AMD Ryzen 5 7500F has an average benchmark score of 24964, which is only 0.2% lower than the 8400F's score of 25005. This means the 7500F would deliver virtually identical frame rates in Doom, making it a direct performance equivalent. The Intel Core i7-11850H scores 24935 (0.3% lower), and the Intel Core i7-13620H scores 24911 (0.4% lower), both of which would also produce nearly indistinguishable results in this game. On the higher side, the AMD EPYC 9474F scores 25103, which is 0.4% higher, but this server processor is not a practical gaming alternative due to its platform requirements.
