Doom

The AMD Ryzen 7 9700F paired with the AMD Radeon RX 6750 XT delivers a robust 1080p and 1440p experience in Doom, but the data shows a clear shift in bottleneck behavior as the resolution increases. At 1920x1080, the combination posts an average of 242 FPS on Low settings, which drops to 178 FPS on High and 145 FPS on Ultra. Moving to 2560x1440, the averages remain high—156 FPS on Low, 136 FPS on Medium, 115 FPS on High, and 94 FPS on Ultra—still firmly in competitive territory. However, at 3840x2160, the frame rates fall to 85 FPS on Low, 74 FPS on Medium, 62 FPS on High, and 51 FPS on Ultra, indicating that the rendering load has escalated to a point where the GPU is the primary limiter.

Resolution Scaling

The performance delta between 1080p and 4K is substantial, with the average FPS at Ultra settings collapsing from 145 at 1920x1080 to just 51 at 3840x2160—a drop of roughly 65%. This steep decline is characteristic of a GPU-bound scenario, as the RX 6750 XT's rendering capabilities are increasingly saturated by the pixel count. At 1080p, the frame rates are high enough that the CPU’s role is more prominent, particularly at Low settings where the 242 FPS average suggests the Ryzen 7 9700F can feed the GPU efficiently without becoming a hard ceiling. The scaling from Low to Ultra at 1080p shows a reduction of 97 FPS (from 242 to 145), which is a 40% performance penalty driven by increased shading and texture work.

At 1440p, the pattern continues but with a narrower absolute spread: Low runs at 156 FPS, Medium at 136 FPS, High at 115 FPS, and Ultra at 94 FPS. The drops between settings are relatively consistent, indicating balanced scaling across the quality presets. The 4K results tell a different story, where the gap between Low (85 FPS) and Ultra (51 FPS) is 34 FPS, but the absolute numbers are low enough that responsiveness may suffer in fast-paced scenes. The measured data includes min FPS values for Medium settings: 63 at 4K, 116 at 1440p, and 179 at 1080p, which show that the worst-case frame times scale similarly, reinforcing that the GPU is the limiting factor at higher resolutions. The overall trend suggests that for 4K gameplay, the RX 6750 XT is overextended, while 1440p represents a sweet spot where the combo can maintain high refresh rates without severe compromise.

CPU Role

The Ryzen 7 9700F is an 8-core, 16-thread processor built on the Zen 5 architecture (Granite Ridge) with a 4 nm process node. Its base clock is 3.80 GHz, boosting up to 5.50 GHz, and it carries 32 MB of shared L3 cache alongside 1 MB of L2 per core. In Doom, a title that is not heavily multithreaded, the CPU’s single-thread performance is crucial, and the data reflects that. The PassMark single-thread score of 4691 places it in the 94th percentile among all CPUs, indicating strong per-core capability. This is evident in the 1080p Low results, where the 242 FPS average suggests the CPU can keep up with high draw call rates, though the game engine’s id Tech 6 architecture does scale with multiple cores to a degree, benefiting from the 8-core layout.

The benchmark results for the CPU show a multithread score of 36470, which is competitive with its nearest rivals: the AMD Ryzen 9 7940HX (69875 avg score, deltaPct 0.2), Intel Core i7-14700KF (70163, deltaPct -0.2), AMD Ryzen 9 7950X (69515, deltaPct 0.7), and Intel Core i7-14700K (69355, deltaPct 0.9). These rivals are within a 0.9% performance margin, meaning the 9700F is effectively in the same performance tier for general workloads. For Doom, the CPU’s boost clock of 5.50 GHz likely helps maintain high frame rates at 1080p, where the game’s physics and AI computations are more likely to create CPU bottlenecks. However, the data shows that even at 1080p Ultra (145 FPS), the CPU is not the limiting factor, as the GPU is still the primary constraint given the frame rate drop from Low to Ultra. The CPU’s TDP of 65 W and dual-channel DDR5 memory support (89.6 GB/s bandwidth) are adequate for this workload, but the game’s performance is more sensitive to GPU throughput.

GPU Role

The AMD Radeon RX 6750 XT is a RDNA 2.0 architecture GPU (Navi 22 chip) built on a 7 nm process, featuring 2560 shading units, 160 TMUs, and 64 ROPs. Its 12 GB of GDDR6 memory on a 192-bit bus provides 432.0 GB/s of bandwidth, which is a key asset for Doom’s high-resolution textures. The GPU’s boost clock is 2600 MHz, with a game clock of 2495 MHz, and it achieves a PassMark G3D score of 20700, placing it in the 71st percentile among all GPUs. Its nearest rivals in the benchmark database include the AMD Radeon R9 M395X (25891 avg score, deltaPct 0.5), AMD FirePro W7100 (25856, deltaPct 0.6), AMD FirePro D700 (25842, deltaPct 0.7), and NVIDIA GeForce RTX 3080 Ti Mobile (25740, deltaPct 1.1), all within a 1.1% margin. This indicates that the RX 6750 XT is a mid-range performer, which aligns with its measured FPS in Doom.

The GPU’s role becomes dominant at 1440p and 4K, as the frame rates scale down with resolution. At 2560x1440, the Ultra preset yields 94 FPS, which is playable but not high-refresh territory, while at 3840x2160, Ultra drops to 51 FPS, which is marginal for smooth gameplay. The 12 GB VRAM is sufficient for Doom’s assets, as the game was released in 2016 and does not require excessive memory, but the GPU’s compute power (13.31 TFLOPS FP32) is the limiting factor at higher resolutions. The pixel rate of 166.4 GPixel/s and texture rate of 416.0 GTexel/s are moderate, and the data shows that the GPU’s performance degrades predictably as resolution increases. The memory bandwidth of 432.0 GB/s helps maintain consistent frame times, as evidenced by the min FPS of 63 at 4K Medium, which is not a severe outlier compared to the 74 average.

How This Combo Ranks

In the database of tested combinations, this CPU-GPU pairing achieves a combo rank of 1301 out of 2930 total combos, placing it slightly above the median. This ranking reflects the balanced nature of the pairing: the Ryzen 7 9700F is a high-end CPU (94th percentile) while the RX 6750 XT is a mid-range GPU (71st percentile), so the combo’s overall position is dragged down by the GPU’s relative weakness. The data indicates that for Doom, the GPU is the bottleneck at 1440p and 4K, but at 1080p, the combo is capable of exceeding 240 FPS on Low settings, which is a strong result for competitive play. The rank of 1301 suggests that many other combos with faster GPUs would outperform this pairing at higher resolutions, but the CPU’s strength ensures that it does not hold back performance in CPU-bound scenarios.

The percentile gap between the CPU (94th) and GPU (71st) highlights an imbalance, but for Doom specifically, the game’s optimization means that even a mid-range GPU can deliver high frame rates at 1080p and 1440p. The combo rank is a holistic metric across all tested games, but in Doom, the pairing’s performance is more favorable than the rank suggests, given the high FPS numbers at lower resolutions. The data shows that this combo is best suited for 1080p and 1440p gaming, where it can leverage the CPU’s single-thread strength and the GPU’s adequate throughput, rather than 4K, where the GPU becomes the clear limiting factor.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets. At 1920x1080, the average FPS ranges from 242 on Low to 145 on Ultra, with Medium at 210 and High at 178. The min FPS for Medium is 179, with a max of 242, indicating consistent frame delivery. At 2560x1440, the averages are 156 (Low), 136 (Medium), 115 (High), and 94 (Ultra). The min FPS for Medium is 116, with a max of 157, showing a moderate spread. At 3840x2160, the averages are 85 (Low), 74 (Medium), 62 (High), and 51 (Ultra), with min FPS for Medium at 63 and max at 85. These numbers illustrate a clear progression: the combo is highly capable at 1080p, where even Ultra settings exceed 144 FPS, and remains playable at 1440p, but struggles to maintain 60 FPS at 4K Ultra.

The data does not include min or max FPS for Low, High, or Ultra settings, but the Medium values provide insight into frame pacing. At 1080p Medium, the min FPS of 179 is only 31 FPS below the average, indicating stable performance. At 1440p Medium, the min of 116 is 20 FPS below the average of 136, which is a reasonable variance. At 4K Medium, the min of 63 is 11 FPS below the average of 74, showing tighter frame times at higher resolutions due to GPU saturation. For Ultra settings, the averages are 145, 94, and 51 at 1080p, 1440p, and 4K respectively, which are the lowest across all presets, confirming that the Ultra preset imposes the heaviest load on the GPU. The Low preset at 1080p (242 FPS) is the only configuration that approaches the CPU’s potential limit, suggesting that the Ryzen 7 9700F can drive frame rates well above 200 FPS when the GPU is not constrained.
