Doom

The AMD Ryzen 5 7400F and AMD Radeon RX 7700 XT combination delivers a compelling 1080p and 1440p experience in Doom, with performance scaling that reveals a system balanced between CPU and GPU capabilities. The data shows a clear hierarchy where resolution increases place progressively more strain on the graphics card, while the processor maintains high framerates even at lower settings. This analysis explores the measured FPS across all settings and resolutions, the distinct roles of the CPU and GPU, and how this pairing ranks among the thousands of tested combinations.

Resolution Scaling

The measured FPS data for this combo shows a predictable and steep decline as resolution increases from 1920x1080 to 3840x2160. At High settings, the average framerate drops from 194 FPS at 1080p to 126 FPS at 1440p, a reduction of 68 FPS. Pushing further to 4K at High settings yields an average of 68 FPS, which is exactly half the 1080p figure. This pattern strongly suggests that the GPU becomes the primary limiting factor at higher resolutions, as the pixel count quadruples from 1080p to 4K, demanding significantly more fill rate and memory bandwidth.

The scaling from Low to Ultra settings at each resolution provides further insight. At 1080p, the spread between Low (264 FPS) and Ultra (159 FPS) is 105 FPS, indicating that the CPU has ample headroom to feed the GPU even at maximum settings. However, at 4K, the same settings spread narrows to 37 FPS (93 FPS at Low versus 56 FPS at Ultra). This narrowing is a classic sign of GPU-bound operation: when the graphics card is saturated with pixel work, changing settings has a proportionally smaller impact on the final framerate.

The most telling statistic is the performance cliff between 1440p and 4K. At Medium settings, 1440p delivers 149 FPS, but 4K drops to 81 FPS, a 46% reduction. This is a much larger percentage drop than the 24% reduction seen when moving from 1080p Medium (230 FPS) to 1440p Medium (149 FPS). The data implies that the RX 7700 XT's 12 GB of VRAM and 432.0 GB/s bandwidth are sufficient for 1440p, but the 4K resolution pushes the renderer into a zone where memory bandwidth and pixel throughput become critical bottlenecks.

Interestingly, the framerate ratios between resolutions are not perfectly linear. At Low settings, 1080p yields 264 FPS, 1440p yields 171 FPS (65% of 1080p), and 4K yields 93 FPS (35% of 1080p). If the GPU were the sole bottleneck, these ratios would more closely mirror the pixel count differences. The fact that 1440p achieves 65% of the 1080p framerate, rather than the theoretical 44% (1080p pixels divided by 1440p pixels), suggests that at 1080p Low, the CPU is beginning to limit performance. The Ryzen 5 7400F, with its 6 cores and 12 threads, appears to cap framerates in the 260-270 FPS range, which is why 1080p Low and Medium results are closer together than at other resolutions.

CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor based on the Zen 4 architecture, running on the AM5 socket. Its base clock of 3.70 GHz and boost clock of 4.70 GHz provide the single-thread performance necessary for high framerate gaming. In Doom, a game that scales well with multiple cores, the 12 threads are utilized effectively, but the data suggests that raw single-core speed is more critical than thread count for achieving the highest framerates. The CPU's Cinebench R23 scores of 21,765 multi-core and 3,072 single-core place it in the 83rd percentile of all CPUs, indicating it is a strong performer for gaming workloads.

The CPU's role in this combo is most evident at 1080p Low settings, where the average framerate of 264 FPS is likely close to the CPU's maximum output. The fact that 1080p Medium achieves 230 FPS, only 34 FPS lower than Low, while 1080p Ultra drops to 159 FPS, suggests that the GPU becomes more involved as settings increase. The CPU is not the primary bottleneck at Ultra settings, as the GPU's workload grows with more complex shading and effects.

Comparing the 7400F to its nearest rivals, the data shows it is nearly identical in average benchmark score to the Intel Core i5-14600T (deltaPct of 0.1%) and the AMD Ryzen 7 PRO 6850H (deltaPct of -0.2%). In practical terms, this means the 7400F should deliver essentially the same CPU-bound framerates in Doom as those processors. The 83rd percentile ranking confirms that this CPU is well above average for gaming, and its 65W TDP suggests it can sustain boost clocks without thermal throttling, which is crucial for maintaining consistent framerates over long sessions.

The memory bandwidth of 83.2 GB/s for the dual-channel DDR5 interface is another factor. In a fast-paced FPS like Doom, the CPU needs to quickly access game state and geometry data. The 32 MB of shared L3 cache helps here, as it can store frequently accessed data closer to the cores. However, the measured FPS at 1080p Low (264 FPS) is not exceptionally high for a modern CPU, which hints that the game's engine might have a framerate ceiling or that the CPU is being held back by other factors like memory latency. The PassMark single-thread score of 3,689 supports the notion that this CPU is capable, but not elite, for single-threaded tasks.

GPU Role

The AMD Radeon RX 7700 XT is a RDNA 3.0 architecture GPU with 3,456 shading units, 216 texture mapping units, and 96 raster output units. Its boost clock of 2544 MHz and game clock of 2171 MHz are high for the current generation, and the 12 GB of GDDR6 memory on a 192-bit bus provides 432.0 GB/s of bandwidth. This memory configuration is critical for Doom, which can be VRAM-hungry at high resolutions and texture settings. The GPU's PassMark G3D score of 22,547 places it in the 67th percentile of all GPUs, showing it is a solid mid-to-high-range card.

The GPU's dominance becomes clear when examining the 4K results. At 4K Ultra, the combo averages 56 FPS, which is below the 60 FPS target that many gamers consider smooth. This low result is directly attributable to the GPU's pixel filling capabilities. The 96 ROPs and 244.2 GPixel/s pixel rate are sufficient for 1440p Ultra (103 FPS), but the 4K resolution demands four times the pixel throughput of 1080p, overwhelming the GPU's resources. The fact that 4K Low (93 FPS) is significantly higher than 4K Ultra (56 FPS) proves that the GPU is the limiting factor at this resolution.

At 1440p, the GPU shows its strengths. The 149 FPS average at Medium settings is an excellent result, and even Ultra settings maintain 103 FPS. The 12 GB VRAM capacity is not a constraint at this resolution, as the game's textures fit comfortably within the memory pool. The GDDR6 memory running at 2250 MHz (18 Gbps effective) provides enough bandwidth to avoid stuttering, which is reflected in the minimum FPS of 127 at 1440p Medium. This suggests that the memory subsystem is not a bottleneck at 1440p.

Comparing the RX 7700 XT to its nearest rivals, it is remarkably close to the NVIDIA GeForce RTX 5060 Mobile (deltaPct of 0.5%) and the RTX 4060 Mobile (deltaPct of -0.8%). The desktop RTX 2080 is just 1.5% faster in average benchmark score. This means that in Doom, the 7700 XT should deliver framerates nearly identical to those of the RTX 2080, which is notable given the generational leap in architecture. The GPU's 54 ray tracing cores are not heavily utilized in Doom, as the game primarily uses traditional rasterization, but they do contribute to the overall feature set.

Measured FPS Breakdown

The measured FPS data provides a complete picture of this combo's performance across three resolutions and four settings presets. At 1920x1080, the results are consistently high: Low averages 264 FPS, Medium averages 230 FPS with a minimum of 196 FPS and a maximum of 265 FPS, High averages 194 FPS, and Ultra averages 159 FPS. These numbers indicate that 1080p is well within the capabilities of this system, with even the most demanding settings exceeding 150 FPS.

At 2560x1440, the performance remains strong but shows the GPU's growing influence. Low settings produce 171 FPS, Medium produces 149 FPS (minimum 127 FPS, maximum 171 FPS), High produces 126 FPS, and Ultra produces 103 FPS. The drop from 1080p to 1440p is approximately 35% across all settings, which is less than the 56% increase in pixel count, confirming that the CPU is still contributing to performance at this resolution.

The 3840x2160 results reveal the GPU's limitations. Low settings achieve 93 FPS, Medium achieves 81 FPS (minimum 69 FPS, maximum 93 FPS), High achieves 68 FPS, and Ultra drops to 56 FPS. The framerate scaling from Low to Ultra at 4K is not linear, with a 40% reduction from Low to Ultra. This suggests that the GPU's shading units and memory bandwidth are increasingly strained as quality settings increase, leading to a more pronounced performance penalty than at lower resolutions.

The minimum FPS data points, where available, are crucial for understanding gameplay smoothness. At 1440p Medium, the minimum of 127 FPS ensures no noticeable stuttering. At 4K Medium, the minimum of 69 FPS is still above the 60 FPS threshold, but it leaves little headroom for demanding scenes. The lack of minimum FPS data for High and Ultra presets at all resolutions is a gap in the dataset, but the averages suggest that these settings would have lower minimums.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. For 1080p gamers with high-refresh-rate monitors (144Hz or above), the High preset is recommended. It delivers 194 FPS average, which comfortably exceeds 144Hz, and the visual quality improvement over Medium is noticeable. The Ultra preset at 159 FPS is also viable for 144Hz displays, but the 35 FPS difference between High and Ultra may not justify the visual gains unless the monitor supports 165Hz or higher.

For 1440p, the Medium preset is the best choice for most users. The 149 FPS average and 127 FPS minimum provide a smooth experience even on 144Hz displays, and the visual quality is high. The High preset at 126 FPS is also acceptable for 120Hz monitors, but its lower minimum FPS could cause occasional dips below the refresh rate. Ultra at 103 FPS is suitable for 100Hz displays, but the performance drop from Medium is significant, so Medium is the more balanced recommendation.

For 4K gaming, the High preset at 68 FPS average is the best option for a near-60 FPS experience. The Ultra preset drops to 56 FPS, which may be noticeable in fast-paced action. The Medium preset at 81 FPS is a strong alternative if the user prefers smoother motion over graphical fidelity. The Low preset at 93 FPS is viable for competitive play, but the visual compromise is substantial. Given that 4K Ultra falls below 60 FPS, the recommendation is to use High settings for a balance of quality and performance, or Medium for a more consistent framerate.

Generally, the data suggests that Medium settings offer the best "sweet spot" across all resolutions, as they provide a significant performance boost over High and Ultra while maintaining acceptable visual quality. For users with adaptive sync displays, the Medium preset's higher minimum FPS ensures a tear-free experience even during demanding scenes. This system is not recommended for 4K Ultra settings, as the 56 FPS average is below the ideal threshold for smooth gameplay.
