Doom

The AMD Ryzen 5 5600F paired with the AMD Radeon RX 6700 XT delivers a thoroughly playable experience in Doom, but the data reveals a clear stratification between CPU-bound and GPU-bound operating points. At 1080p, the combo produces frame rates exceeding 230 FPS on Low settings, while at 4K Ultra, it dips to an average of 49 FPS. The benchmark results indicate that this pairing is exceptionally strong for high-refresh-rate 1080p and 1440p gaming, with the primary bottleneck shifting decisively to the graphics card as resolution increases.

Resolution Scaling

The measured FPS data shows how the workload transforms across the three tested resolutions. At 1080p with Low settings, the combo achieves 230 FPS, which drops to 149 FPS at 1440p and 81 FPS at 4K. This progression represents a 35% performance loss from 1080p to 1440p, and a further 46% loss from 1440p to 4K. The scaling pattern is consistent across all settings presets, indicating that the RX 6700 XT is the primary performance limiter at higher resolutions.

The relationship between resolution and settings reveals the CPU's headroom. At 1080p, moving from Low to Ultra only reduces the average frame rate from 230 to 138 FPS, a 40% drop. However, at 4K, the same settings change reduces performance from 81 to 49 FPS, a 40% drop as well. The proportional penalty is nearly identical, but the absolute impact is more severe at 4K because the starting point is already lower. This suggests that the CPU is not the limiting factor at any resolution; rather, the GPU's pixel throughput is the dominant constraint.

The 4K Ultra result of 49 FPS average is the only sub-60 FPS result in the entire dataset. This indicates that the combo is not optimized for 4K gaming with maximum quality settings. The 4K Medium result, at 70 FPS, provides a 43% improvement over Ultra, while 4K Low jumps to 81 FPS, a 65% improvement over Ultra. The scaling from 4K Medium to 4K Low (81 vs 70 FPS) demonstrates that even modest quality reductions yield substantial performance gains at this resolution.

At 1440p, the story changes. The Ultra preset delivers 90 FPS, which is comfortably above the 60 FPS threshold for smooth gameplay. The High preset reaches 110 FPS, and Low pushes to 149 FPS. The 1440p results show that this combo is well-suited for high-refresh-rate monitors (144Hz class) when settings are kept at High or below. The 1080p results are even more impressive, with all presets exceeding 138 FPS, and Low reaching 230 FPS, which is suitable for 240Hz displays.

FAQ

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

A: Based on the measured data, 2560x1440 offers the best balance of visual fidelity and performance. The High preset at this resolution averages 110 FPS, which is above the 100 FPS mark typically desired for fast-paced shooters. The Ultra preset still maintains 90 FPS, providing a smooth experience even with maximum quality settings.

*Q: Can this system handle 4K gaming in Doom?*

A: The RX 6700 XT and Ryzen 5 5600F can run Doom at 4K, but only with settings adjustments. The 4K Medium preset averages 70 FPS with a minimum of 60 FPS, which is playable. The 4K High and Ultra presets drop to 59 and 49 FPS respectively, which may not be ideal for competitive play.

Q: How does the CPU affect performance at 1080p?

A: The Ryzen 5 5600F with 6 cores and 12 threads appears to have ample headroom at 1080p. The difference between 1080p Low (230 FPS) and 1080p Ultra (138 FPS) is entirely attributable to GPU load, not CPU limitations. The CPU's single-thread score of 2872 in Passmark indicates strong per-core performance that is sufficient for Doom's engine.

Q: What is the performance difference between High and Ultra settings?

A: The data shows a consistent penalty for Ultra settings across all resolutions. At 1080p, Ultra is 18% slower than High (138 vs 169 FPS). At 1440p, the penalty is 18% as well (90 vs 110 FPS). At 4K, Ultra is 17% slower than High (49 vs 59 FPS). The scaling is remarkably consistent, suggesting that Ultra settings add a fixed amount of shader work.

Q: Is the RX 6700 XT the bottleneck in this system?

A: Yes, benchmark results indicate the GPU is the limiting component at all resolutions. The GPU's Passmark G3D score of 19786 places it in the 72nd percentile of all GPUs, and its nearest rival is the RTX 4070 Mobile with a delta of 0%. The CPU's Passmark multithread score of 19236 is in the 85th percentile of all CPUs, and the scaling pattern shows no signs of CPU saturation.

Q: What is the minimum FPS I can expect?

A: The only measured minimum FPS values are for the Medium preset at each resolution: 60 FPS at 4K, 110 FPS at 1440p, and 170 FPS at 1080p. These minimums are notably close to the average FPS for each resolution, indicating stable frame pacing. The Ultra and Low presets do not have reported minimums, but the averages suggest they would remain within acceptable bounds.

Settings Recommendations

The measured data suggests that the High preset is the optimal choice for most users. At 1080p, High delivers 169 FPS, which is 92% of the performance of Low (230 FPS) while providing significantly better visual quality. At 1440p, High achieves 110 FPS, which is 74% of Low's 149 FPS, but still well above the 60 FPS threshold. The High preset also outperforms Ultra by 18% at both 1080p and 1440p, making it the clear sweet spot for performance-per-visual-fidelity.

For users with high-refresh-rate 1440p monitors (144Hz or 165Hz), the Medium preset is recommended. The Medium preset at 1440p averages 130 FPS with a minimum of 110 FPS, which comfortably exceeds the refresh rate of most displays. The 20 FPS difference between Medium and High (130 vs 110 FPS) may be worth sacrificing for those who prioritize frame rate above all else.

The Ultra preset is not recommended for any resolution in Doom. At 1080p, it delivers 138 FPS, which is 31 FPS slower than High. At 1440p, it drops to 90 FPS, which is still playable but represents an 18% performance penalty. At 4K, Ultra falls below the 60 FPS threshold at 49 FPS, making it unsuitable for smooth gameplay. The visual improvement from High to Ultra does not justify the substantial performance cost.

For 4K gaming, the Medium preset is the only viable option. The 4K Medium result of 70 FPS average with a 60 FPS minimum provides a consistent experience. The 4K High preset at 59 FPS is borderline, and the 4K Low preset at 81 FPS sacrifices too much visual quality. Users with 4K displays should prioritize Medium settings to maintain playable frame rates.

How This Combo Ranks

The AMD Ryzen 5 5600F and AMD Radeon RX 6700 XT combination ranks 1506 out of 2930 tested combos in Doom. This places the pairing in the 49th percentile of all tested systems, indicating a mid-pack performance level. The rank is somewhat surprising given the strong absolute FPS numbers, but it reflects the fact that many higher-end GPUs and CPUs achieve significantly higher frame rates in this well-optimized title.

The GPU's relative performance helps contextualize this ranking. The RX 6700 XT has an average benchmark score of 27425, which places it in the 72nd percentile of all GPUs. Its nearest rival, the NVIDIA GeForce RTX 4070 Mobile, scores 27435, a delta of 0%. The desktop RTX 3090 scores 27565, which is only 0.5% higher. This suggests that the RX 6700 XT is a strong mid-range performer, but Doom's engine is capable of leveraging much more powerful hardware.

The CPU's ranking is more favorable. The Ryzen 5 5600F has an average benchmark score of 36945, placing it in the 85th percentile of all CPUs. Its nearest rivals are the Intel Core Ultra 5 225 (36938, 0% delta) and the AMD Ryzen 5 5500X3D (37018, -0.2% delta). The CPU's strong relative performance does not translate into a higher combo rank, confirming that the GPU is the limiting factor in this pairing.

The 1506th rank out of 2930 combos means that approximately 1424 tested configurations outperform this one in Doom. This is expected given the GPU's mid-range positioning. The combo still delivers excellent absolute performance, with 1080p High at 169 FPS and 1440p High at 110 FPS, but it cannot compete with high-end systems that feature GPUs like the RTX 3090.

CPU Role

The AMD Ryzen 5 5600F is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Vermeer. It operates at a base clock of 3.00 GHz and a boost clock of 4.00 GHz, with a 65 W TDP. The CPU has 32 MB of shared L3 cache and supports DDR4 memory with a dual-channel bus delivering 51.2 GB/s of bandwidth. These specifications are well-suited for gaming workloads, particularly in a title like Doom that is not heavily multithreaded.

In the Passmark benchmark suite, the 5600F scores 2872 in single-thread tests and 19236 in multithread tests. The single-thread score is particularly relevant for Doom, which relies heavily on per-core performance for game logic and physics. The CPU's floating-point math score of 34548 and integer math score of 59339 indicate robust compute capabilities that are unlikely to bottleneck the GPU in most scenarios.

The measured FPS data confirms that the CPU is not the limiting factor in this combo. At 1080p Low, the system achieves 230 FPS, which is a frame rate that would challenge many CPUs. The fact that the 5600F can sustain this performance without dropping below the GPU's capabilities suggests that it has significant headroom. The 1080p Medium result of 200 FPS (with a 170 FPS minimum) further validates this conclusion.

The CPU's memory bandwidth of 51.2 GB/s and PCIe Gen 4 support with 20 lanes provide ample data transfer capabilities for the RX 6700 XT. The GPU's 384.0 GB/s memory bandwidth and 192-bit bus are more than sufficient for Doom's texture streaming requirements. The combination of a capable CPU and a mid-range GPU creates a balanced system where the GPU becomes the bottleneck only at higher resolutions.

The CPU's 85th percentile ranking among all CPUs, with an average benchmark score of 36945, places it in close competition with the Intel Core Ultra 5 225 (36938) and the AMD Ryzen 5 5500X3D (37018). This indicates that the 5600F offers competitive performance in its class, and the 0% delta with the Core Ultra 5 225 suggests that users would not see a meaningful difference in Doom between these processors.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the combo's performance across all settings and resolutions. At 1920x1080, the results show a progression from 230 FPS on Low to 200 FPS on Medium, 169 FPS on High, and 138 FPS on Ultra. The Medium preset reports a minimum of 170 FPS and a maximum of 230 FPS, indicating tight frame pacing. The 1080p results demonstrate that this combo is capable of driving high-refresh-rate monitors at any settings level.

At 2560x1440, the performance drops as expected. The Low preset averages 149 FPS, Medium averages 130 FPS (with a minimum of 110 FPS and maximum of 149 FPS), High averages 110 FPS, and Ultra averages 90 FPS. The 1440p results are notable for maintaining playable frame rates even at Ultra settings, which is a significant achievement for a mid-range GPU. The Medium preset's 130 FPS average with a 110 FPS minimum makes it the best choice for 144Hz displays.

At 3840x2160, the combo begins to struggle with higher settings. The Low preset averages 81 FPS, Medium averages 70 FPS (with a minimum of 60 FPS and maximum of 81 FPS), High averages 59 FPS, and Ultra averages 49 FPS. The 4K results highlight the GPU's limitations at this resolution. Only the Low and Medium presets maintain average frame rates above 60 FPS, and the Ultra preset falls below the 50 FPS mark.

The Medium preset is the only one with complete min/max data across all three resolutions. At 1080p, the minimum is 170 FPS and the maximum is 230 FPS, giving a range of 60 FPS. At 1440p, the minimum is 110 FPS and the maximum is 149 FPS, a range of 39 FPS. At 4K, the minimum is 60 FPS and the maximum is 81 FPS, a range of 21 FPS. This data shows that frame pacing becomes more consistent as resolution increases, which is a positive indicator for stability at higher resolutions.

The performance deltas between settings are also informative. At 1080p, the difference between Low and Ultra is 92 FPS (230 to 138), while at 1440p the difference is 59 FPS (149 to 90), and at 4K the difference is 32 FPS (81 to 49). The absolute performance penalty for Ultra settings decreases with resolution, but the percentage penalty remains roughly constant at 40% across all resolutions. This suggests that the GPU's workload scales uniformly with resolution, and the CPU is not introducing any additional bottlenecks at lower resolutions.
