Doom

The AMD Ryzen 5 7400F and AMD Radeon RX 6700 XT combination delivers a highly capable Doom experience, with the data showing a clear trend: this pairing is built for high-refresh-rate 1080p and 1440p gaming, while 4K remains playable but requires settings adjustments. Benchmark results indicate the system scales predictably with resolution, and the performance ceiling is consistently defined by the graphics card rather than the processor.

Resolution Scaling

The measured FPS data reveals a classic GPU-bound scaling pattern. At 1080p with Low settings, the combo achieves an average of 230 FPS. Moving to 1440p Low drops that to 149 FPS, a reduction of roughly 35%. At 4K Low, the average falls to 81 FPS, which is about 46% lower than the 1440p figure. This steep decline as resolution increases is the signature of a system where the Radeon RX 6700 XT is the primary limiting factor; the CPU has ample headroom to feed frames at lower resolutions, but the GPU's rendering throughput becomes the bottleneck as pixel count rises.

The scaling pattern is even more telling when examining the High settings tier. The 1080p High average is 169 FPS, which drops to 110 FPS at 1440p and then to 59 FPS at 4K. The gap between 1440p and 4K here is severe—a 46% performance loss—which strongly suggests that the 12 GB VRAM and 192-bit memory bus of the GPU are being saturated at the higher resolution. The data indicates that 4K High is right on the edge of playability, with the average sitting just below the 60 FPS threshold that many users consider the minimum for smooth gameplay.

The Low settings tier tells a slightly different story. At 1080p Low, the system hits 230 FPS, which is an exceptional result that shows the CPU's 6 cores and 12 threads are more than sufficient for this game's engine. The transition to 1440p Low (149 FPS) and 4K Low (81 FPS) shows less dramatic percentage drops than the High tier, indicating that at Low settings, the GPU is less stressed by memory bandwidth and can rely more on raw compute. This suggests that for users targeting 4K, dropping from High to Low settings yields a 37% performance improvement (from 59 to 81 FPS), which is the difference between a stuttery experience and a smooth one.

FAQ

Q: Can this combo run Doom at 4K with playable frame rates?

A: Yes, but only at lower settings. The data shows 81 FPS average at 4K Low, 70 FPS at 4K Medium, 59 FPS at 4K High, and 49 FPS at 4K Ultra. For a consistent 60+ FPS experience, Medium settings at 4K are the safe ceiling.

Q: What is the best resolution for this pairing to maximize refresh rate?

A: At 1080p, the system delivers 230 FPS on Low and 169 FPS on High, which is ideal for 144Hz or 165Hz monitors. At 1440p, it achieves 149 FPS on Low and 110 FPS on High, making 1440p High a strong choice for 120Hz displays.

Q: How does the CPU performance compare to its nearest rivals?

A: The Ryzen 5 7400F scores an average benchmark of 32750, placing it 0.1% ahead of the Intel Core i5-14600T and 0.2% ahead of the Intel Core Ultra 7 155H. It trails the AMD Ryzen 7 PRO 6850H by 0.2%, making all four processors statistically equivalent in general compute.

Q: Is the RX 6700 XT a bottleneck at 1080p?

A: The data suggests no. At 1080p Low, the combo hits 230 FPS, which is a very high ceiling. The GPU's 13.21 TFLOPS of FP32 performance and 384.0 GB/s bandwidth are sufficient to keep up with the CPU's frame generation at this resolution.

Q: What is the frame time consistency like at different settings?

A: The data includes min/max FPS for Medium settings only. At 1080p Medium, the range is 170-230 FPS, with an average of 200. At 1440p Medium, the range is 110-149 FPS, average 130. At 4K Medium, the range is 60-81 FPS, average 70. This shows tighter frame pacing at lower resolutions.

Q: How does this combo rank among all tested systems for Doom?

A: The combination ranks 1506 out of 2930 tested combos, placing it in the 49th percentile of all systems. This puts it slightly below the median, but the rank is heavily influenced by systems with much more powerful GPUs.

CPU Role

The Ryzen 5 7400F is a 6-core, 12-thread processor based on the Zen 4 architecture, built on a 5 nm process. Its base clock is 3.70 GHz, boosting up to 4.70 GHz. In this game, the CPU's role appears to be secondary to the GPU, as evidenced by the fact that at 1080p Low, the system achieves 230 FPS without any apparent CPU limitation. The processor has a strong single-thread foundation, scoring 3689 in PassMark's single-thread test and 3072 in Cinebench R23 single-core, which is critical for game logic and draw call submission.

The multi-threaded performance is also robust, with a Cinebench R23 multi-core score of 21765 and a PassMark multi-thread score of 25645. This ensures that background tasks and the game's engine threads are handled without causing frame drops. The processor's 32 MB of shared L3 cache is another asset, as Doom's engine benefits from lower latency memory access patterns. The CPU's 83rd percentile ranking among all CPUs, with an average benchmark score of 32750, places it comfortably above average, and the data shows it is not the limiting factor in any resolution or settings tier tested.

However, the CPU's performance relative to its nearest rivals is notable for its near-exact parity. The deltaPct values against the Intel Core i5-14600T (0.1%), Intel Core Ultra 7 155H (0.2%), and AMD Ryzen AI 7 PRO 360 (0.3%) are all within a fraction of a percent. This means that swapping between these processors would yield no measurable difference in Doom's frame rates. The only rival with a negative delta is the AMD Ryzen 7 PRO 6850H at -0.2%, which is also negligible. This indicates that Doom is not sensitive to CPU selection among this performance class, and the 7400F's 6 cores are sufficient for the game's multithreaded workload.

How This Combo Ranks

The combo's rank of 1506 out of 2930 tested combinations places it in the 49th percentile for Doom performance. This rank is a holistic measure that considers all tested CPU-GPU pairings, and it indicates that while this system is capable, it sits just below the median of the entire database. Given that the GPU is the primary driver of frame rates in this game, the rank reflects the RX 6700 XT's position rather than the CPU's capabilities.

The GPU's own percentile ranking is 72nd among all GPUs, with an average benchmark score of 27425. This is significantly higher than the combo's overall rank, which suggests that the combination's position is dragged down by the CPU's relatively lower 83rd percentile. However, the actual in-game data shows that the CPU does not bottleneck the GPU, as evidenced by the 230 FPS result at 1080p Low. The rank is therefore a statistical artifact of comparing across many different system configurations, some of which pair higher-end CPUs with similar GPUs.

Compared to its nearest GPU rivals, the RX 6700 XT is essentially tied with the NVIDIA GeForce RTX 4070 Mobile (0% delta) and trails the NVIDIA GeForce RTX 3090 by only 0.5%. It is 1.1% ahead of the NVIDIA RTX PRO 4000 Blackwell. This indicates that the GPU's raw compute performance is competitive with much more expensive options in other form factors. The combo rank of 1506, therefore, represents a system that is better than its raw ranking suggests, particularly for a game like Doom that favors GPU throughput.

GPU Role

The Radeon RX 6700 XT is the dominant component in this pairing, and the data clearly shows that it defines the performance envelope. With 12 GB of GDDR6 memory on a 192-bit bus, the GPU has a bandwidth of 384.0 GB/s. This is sufficient for high-texture workloads at 1080p and 1440p, but the 4K results indicate that memory bandwidth becomes a constraint at higher resolutions. The base clock of 2321 MHz and boost clock of 2581 MHz, with a game clock of 2424 MHz, drive 2560 shading units, 160 TMUs, and 64 ROPs, yielding 13.21 TFLOPS of FP32 compute.

The GPU's role in Doom is evident from the scaling pattern. At 1080p High, the system produces 169 FPS, but at 4K High, it drops to 59 FPS. This is a 65% reduction in performance, which is steeper than the 4x increase in pixel count would suggest. The reason is that at 4K, the GPU is not only processing more pixels but also dealing with increased memory pressure. The 12 GB VRAM is not exhausted at 4K High, but the 192-bit bus limits the rate at which textures and geometry can be streamed.

The GPU's benchmark scores reinforce this interpretation. In PassMark's G3D test, it scores 19786, and in Geekbench Vulkan, it scores 93500. These results place it in the 72nd percentile among all GPUs, and its nearest rival, the RTX 3090, is only 0.5% faster in average benchmark score. This suggests that the RX 6700 XT delivers exceptional value in raw compute, but its memory subsystem is less capable than its compute performance, which is why the 4K results suffer disproportionately compared to 1080p.

Measured FPS Breakdown

The complete dataset reveals a consistent hierarchy across all settings and resolutions. At 1080p, the system delivers 230 FPS on Low, 200 FPS on Medium (with a range of 170-230), 169 FPS on High, and 138 FPS on Ultra. This shows that Ultra settings impose a 40% performance penalty compared to Low, but even at Ultra, the frame rate is high enough for competitive play on high-refresh monitors.

At 1440p, the figures are 149 FPS on Low, 130 FPS on Medium (range 110-149), 110 FPS on High, and 90 FPS on Ultra. The drop from 1080p to 1440p is consistent, averaging about 35% across all settings. This resolution is the sweet spot for this combo, as it offers a balance between visual fidelity and frame rate, with even Ultra settings maintaining a 90 FPS average.

At 4K, the results are more constrained: 81 FPS on Low, 70 FPS on Medium (range 60-81), 59 FPS on High, and 49 FPS on Ultra. The Medium setting is the best option for 4K, as it maintains an average above 60 FPS while offering improved visuals over Low. The High setting dips below 60 FPS, and Ultra is not recommended for smooth play. The data shows a clear recommendation: for 4K, use Medium settings to stay above the 60 FPS threshold; for 1440p, High settings are ideal; and for 1080p, all settings are playable, with Ultra still delivering 138 FPS.
