Doom

How This Combo Ranks

The AMD Ryzen 5 8400F paired with the AMD Radeon RX 5700 XT lands at rank 1281 out of 1681 tested combos in Doom. That places this pairing in the lower-middle portion of the database, meaning it will handle the game but won't top any leaderboards. The GPU sits at the 68th percentile among all tested graphics cards, while the CPU reaches the 82nd percentile, so the processor is comparatively stronger than the graphics card in this matchup.

Looking at the nearest rivals clarifies the picture. The RX 5700 XT's average benchmark score of 24731 is nearly identical to the NVIDIA RTX A5000 Mobile's 24763, a delta of just -0.1%. It also edges out the Intel Arc A350M by 0.3% and the NVIDIA GeForce RTX 5060 Mobile by 0.6%. These are tight margins, so the GPU is performing right in line with its expected tier. On the CPU side, the Ryzen 5 8400F's average score of 25064 is essentially tied with the AMD Ryzen 7 2700X at 25057, and it trails the AMD Ryzen AI 5 PRO 340 by only 0.1%. The Ryzen 5 7500F is 0.3% behind. This indicates the CPU is a solid mid-range performer that won't bottleneck the GPU in most scenarios.

The combo rank of 1281 out of 1681 suggests that while neither component is exceptional in this title, the pairing works adequately. The data shows a system that can deliver playable frame rates across most settings, but it's not optimized for maximum competitive performance or high-refresh-rate dominance at higher resolutions.

Settings Recommendations

The measured FPS data offers a clear hierarchy of settings for this game. At 1080p, the Low preset delivers 189.1 FPS, which is the highest average recorded across all resolutions and settings. Medium drops to 165.5 FPS, High to 136.9 FPS, and Ultra to 113.6 FPS. All four presets at 1080p exceed the 100 FPS threshold, so even Ultra is fully playable on a standard 60Hz or even 144Hz display.

At 1440p, the story changes slightly. Low produces 121.3 FPS, Medium 105.7 FPS, and High 90.7 FPS, while Ultra falls to 73 FPS. The jump from High to Ultra at this resolution costs roughly 17.7 FPS, which is significant. For a balance of visual fidelity and smooth motion, the High preset at 1440p appears to be the sweet spot, keeping the average comfortably above 90 FPS. Pushing to Ultra sacrifices too much performance for marginal visual gains.

At 4K, the situation becomes more constrained. Low yields 63.4 FPS, Medium 57.8 FPS, High 50.9 FPS, and Ultra only 42.5 FPS. Only the Low preset stays above the 60 FPS playable threshold. For 4K users, the recommendation is clear: stick to Low or Medium if you want to maintain smooth gameplay. The data shows that High and Ultra at 4K dip below 60 FPS, which many players find unacceptable for a fast-paced FPS like Doom.

The best experience per the measured rows is the High preset at 1440p, offering 90.7 FPS with a good visual quality-to-performance ratio. If you prefer maximum smoothness, the Low preset at 1080p at 189.1 FPS is the fastest option available.

Resolution Scaling

The FPS drop from 1080p to 4K reveals important information about the limiting component. Moving from 1080p High at 136.9 FPS to 1440p High at 90.7 FPS represents a 33.7% reduction. Dropping further to 4K High at 50.9 FPS is a 62.8% reduction from the 1080p baseline. These are steep declines that indicate the GPU is the primary bottleneck in this pairing.

Consider the Low preset scaling: 189.1 FPS at 1080p, 121.3 FPS at 1440p, and 63.4 FPS at 4K. The 4K figure is only 33.5% of the 1080p number. This pattern — where higher resolutions cause proportionally larger FPS drops — is characteristic of a graphics-card-limited scenario. If the CPU were the constraint, the FPS would remain relatively flat across resolutions because the processor's workload doesn't change much with pixel count.

The RX 5700 XT's 8 GB of GDDR6 memory on a 256-bit bus with 448.0 GB/s bandwidth is being pushed hard at 4K. The data shows that even at Low settings, 4K only reaches 63.4 FPS, which suggests the GPU's raw compute power — 9.754 TFLOPS FP32 — is insufficient for high-refresh 4K gaming in this title. The CPU, with its 6 cores and 12 threads, is likely not the limiting factor here; the consistent FPS drops with increasing resolution point squarely at the GPU.

In Doom, the CPU's role is secondary to the GPU. The FPS scaling from 1080p to 4K shows the processor isn't creating a bottleneck at any resolution. At 1080p Low, the system achieves 189.1 FPS, which is a high frame rate that would stress many CPUs. The 8400F handles this without issue, maintaining a 0% delta against the Ryzen 7 2700X in average scores. The 12 threads and boost clock of 4.70 GHz provide sufficient responsiveness for the game's AI and physics calculations.

The CPU's 3DMark scores support its gaming adequacy: 951 in single-thread, 3563 in 4-thread, and 6165 in max-thread tests. These numbers indicate the processor scales well with additional threads, which helps in Doom's more demanding scenes. The 82nd percentile ranking confirms that this CPU is well above average for gaming, meaning the RX 5700 XT is the component that dictates the overall frame rate in this pairing.
