Doom

The AMD Ryzen 5 8400F and AMD Radeon RX 7600 XT pairing delivers a decisive 1080p experience in Doom, but the data reveals a sharp performance cliff as resolution climbs. This combination ranks in the 33rd percentile of all tested configurations for this title, a position driven by the GPU's limitations at higher pixel counts.

FAQ

*Q: What is the best resolution for this CPU/GPU combo in Doom?*

A: The data shows 1920x1080 is the sweet spot, with every preset averaging above 121 FPS. At 2560x1440, performance drops to a range of 76.5 to 129.1 FPS, while 3840x2160 falls below 72 FPS on all settings.

Q: How does the Ryzen 5 8400F compare to its nearest CPU rivals?

A: The processor's average benchmark score of 25064 places it within 0.3% of the AMD Ryzen 5 7500F (24993) and essentially tied with the AMD Ryzen 7 2700X (25057), showing near-identical raw processing capability in this class.

Q: What is the GPU's standing relative to other graphics cards?

A: The RX 7600 XT holds a 63rd percentile ranking among all GPUs. Its average score of 20146 is 1.9% ahead of the NVIDIA GeForce RTX 2060 SUPER (19774) but 0.6% behind the standard AMD Radeon RX 7600 (20258).

Q: Which settings preset offers the highest frame rate at 4K?

A: The Low preset at 3840x2160 yields 71.9 FPS average, which is the only 4K configuration approaching playable smoothness. The Ultra preset at this resolution drops to 41.4 FPS.

*Q: Is the CPU or GPU the limiting factor in Doom?*

A: The evidence strongly points to the GPU. At 1080p, the frame rate scales dramatically with settings (200.6 FPS at Low vs 121.4 FPS at Ultra), indicating the graphics card is the primary constraint. The CPU's 6-core, 12-thread configuration appears sufficient for this workload.

Q: How many total combinations does this ranking represent?

A: This combo ranks 1118 out of 1681 tested hardware combinations for Doom, placing it in the lower-middle portion of the performance distribution.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, built on a 4 nm process. Its base clock of 4.20 GHz and boost clock of 4.70 GHz provide solid single-thread performance, evidenced by a 3dmark single-thread score of 951 and a Cinebench R23 single-core score of 2943. The 16 MB of shared L3 cache and 83.2 GB/s memory bandwidth on the dual-channel DDR5 interface contribute to responsive gameplay.

In Doom, the CPU appears to be a capable partner rather than a bottleneck. The 3dmark 16-thread score of 6091 and max-thread score of 6165 indicate that multithreaded scaling is modest but adequate for a game that primarily relies on a few strong cores. The processor's 82nd percentile ranking among all CPUs suggests it has ample headroom for this title. However, the game's performance pattern across resolutions reveals that the CPU's influence diminishes quickly once the GPU becomes saturated.

The 8400F's nearest rivals include the AMD Ryzen 7 2700X and the AMD Ryzen 5 7500F, with delta percentages of 0% and 0.3% respectively. This tight clustering in average scores (25057 to 24993) implies that users upgrading from older generations would see minimal CPU-side differences in Doom. The processor's 65W TDP and unlocked multiplier make it an efficient choice, though these characteristics do not directly translate into higher frame rates here.

GPU Role

The AMD Radeon RX 7600 XT is built on the RDNA 3.0 architecture with the Navi 33 chip, fabricated on a 6 nm process. It features 2048 shading units, 128 texture mapping units, and 64 ROPs, with a boost clock of 2755 MHz and a game clock of 2470 MHz. The 16 GB of GDDR6 memory on a 128-bit bus provides 288.0 GB/s of bandwidth, which is substantial for a card in this segment.

The GPU's 63rd percentile ranking among all graphics cards places it in the mid-range tier. Its nearest rival, the standard RX 7600, scores 0.6% higher, suggesting the XT variant's extra memory and slightly higher clocks do not translate into a meaningful benchmark advantage. The 1.9% lead over the RTX 2060 SUPER indicates generational progress, but the data shows the card struggles to maintain high frame rates at demanding resolutions.

In Doom, the RX 7600 XT's performance curve is telling. At 1080p, it delivers 200.6 FPS on Low settings, which indicates a strong rasterization capability. The drop to 121.4 FPS at Ultra represents a 39.5% reduction, showing that the card's fill rate and shading power are taxed by higher quality presets. The 22.57 TFLOPS FP32 throughput and 176.3 GPixel/s pixel rate are the theoretical underpinnings of this behavior, but the measured results demonstrate real-world limits.

How This Combo Ranks

The combination of the Ryzen 5 8400F and RX 7600 XT ranks 1118 out of 1681 tested combos for Doom, placing it in the 33.5th percentile. This is a modest position, suggesting that while the pairing is competent for 1080p gaming, it falls behind a significant portion of tested hardware in this specific title.

The ranking implies that many combinations of newer or higher-tier CPUs and GPUs achieve better results. However, the data indicates that the GPU is the primary driver of this ranking. At 1080p, the combo delivers playable to excellent frame rates across all presets, which suggests the ranking is influenced more by 1440p and 4K performance where the GPU's limitations become apparent. The 63rd percentile GPU ranking versus the 82nd percentile CPU ranking highlights this imbalance — the processor is capable of more, but the graphics card holds the pairing back in higher-resolution scenarios.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a classic GPU-bound scenario. At Ultra settings, performance drops from 121.4 FPS at 1920x1080 to 76.5 FPS at 2560x1440 (a 37% reduction), then further to 41.4 FPS at 3840x2160 (a 66% reduction from 1080p). This steep decline is characteristic of a graphics card reaching its rendering limits as pixel count quadruples.

The Low settings preset shows a similar but less severe pattern: 200.6 FPS at 1080p drops to 129.1 FPS at 1440p (35.6% reduction) and 71.9 FPS at 4K (64.2% reduction). The consistent percentage drops across settings indicate that the GPU's fill rate and memory bandwidth are the limiting factors, rather than any CPU-side constraint. The 288.0 GB/s bandwidth and 128-bit bus are modest for 4K workloads, which explains why the card cannot maintain high frame rates at that resolution even on Low settings.

Measured FPS Breakdown

At 1920x1080, the combo delivers excellent performance across all presets. Low settings produce 200.6 FPS, Medium reaches 173.8 FPS, High achieves 145.4 FPS, and Ultra still maintains 121.4 FPS. These numbers indicate a smooth experience on any 1080p display, with even the most demanding preset exceeding 120 FPS.

Moving to 2560x1440, the frame rates remain respectable but show clear degradation. Low settings yield 129.1 FPS, Medium drops to 112.7 FPS, High comes in at 92.3 FPS, and Ultra falls to 76.5 FPS. The 1440p results suggest that gamers targeting high refresh rates should stick to Medium or Low presets, while those with 60 Hz displays can comfortably use High.

At 3840x2160, the GPU's limitations become stark. Low settings average 71.9 FPS, which is playable but not ideal for fast-paced FPS action. Medium drops to 58.8 FPS, High falls to 48.7 FPS, and Ultra bottoms out at 41.4 FPS. None of these 4K configurations reach the 60 FPS threshold that many players consider the minimum for a competitive shooter like Doom.

Settings Recommendations

For 1920x1080, the Ultra preset at 121.4 FPS provides the best balance of visual fidelity and performance, as it exceeds the 120 FPS mark that high-refresh monitors can utilize. If a player prioritizes maximum frame rates, the Low preset's 200.6 FPS is the clear choice, though the visual trade-offs are significant.

At 2560x1440, the High preset's 92.3 FPS offers a strong experience for 60-100 Hz displays, while the Medium preset at 112.7 FPS is preferable for 120 Hz panels. The Ultra preset's 76.5 FPS is still playable but may feel less responsive in fast-paced combat scenarios.

For 3840x2160, the Low preset's 71.9 FPS is the only viable option for smooth gameplay. The Medium preset's 58.8 FPS is borderline, and the High and Ultra presets at 48.7 and 41.4 FPS respectively are below the playable threshold for a game that demands quick reactions. The data suggests that 4K gaming with this combo requires significant settings compromises, and users should consider 1440p as the practical ceiling for this pairing.
