Doom

The AMD Ryzen 7 7700 and AMD Radeon RX 6750 XT combination delivers a robust performance profile in Doom, with frame rates that scale predictably across resolutions. The data indicates a system where the GPU becomes the primary bottleneck as resolution increases, while the CPU’s strong single-thread performance ensures high ceilings at lower resolutions. Benchmark results show that this pairing is capable of excellent 1080p performance, very good 1440p gameplay, and playable 4K, making it a versatile option for this classic FPS.

Resolution Scaling

The measured FPS data reveals a clear and expected trend: performance degrades as resolution increases, but the rate of decline is not uniform across settings. At 1080p with Low settings, the combo achieves an average of 242 FPS. Moving to 1440p at the same settings drops the average to 156 FPS, a reduction of roughly 35.5%. The step to 4K Low further reduces the average to 85 FPS, which is another 45.5% decline from the 1440p result.

This scaling pattern is typical for a system where the graphics card is the primary limiting factor at higher resolutions. The RX 6750 XT’s 12 GB of VRAM and 192-bit memory interface are sufficient for the game’s demands, but the raw compute throughput required to fill 4K pixels is substantial. The performance gap between 1440p and 4K is much larger than the gap between 1080p and 1440p, indicating that the GPU is working progressively harder as pixel count increases.

At Ultra settings, the trend is even more pronounced. The 1080p Ultra average is 145 FPS, which drops to 94 FPS at 1440p (a 35.2% decrease) and then to 51 FPS at 4K (a 45.7% decrease from 1440p). This shows that the combination of high resolution and maximum graphical fidelity places a significant load on the GPU, pushing it near its limits at 4K. The 4K Ultra result of 51 FPS is right at the threshold of smooth gameplay, suggesting that users targeting 4K should consider High or Medium settings to maintain higher frame rates.

The data suggests that the CPU is not a significant bottleneck in this game. At 1080p Low, where CPU overhead is often most visible, the system still delivers 242 FPS, indicating that the Ryzen 7 7700’s Zen 4 architecture is more than capable of feeding the GPU. The performance drop from 1080p to 1440p is substantial across all settings, which further confirms that the GPU is the limiting component in most scenarios.

FAQ

Q: What is the average frame rate at 1080p with Ultra settings?

A: The average frame rate at 1920x1080 with Ultra settings is 145 FPS. This indicates a very smooth experience for high-refresh-rate monitors, though it is notably lower than the 210 FPS average seen at Medium settings.

*Q: Is this system capable of 4K gaming in Doom?*

A: Yes, it is playable. The 4K High preset delivers an average of 62 FPS, and Low settings push that to 85 FPS. However, the 4K Ultra preset drops to 51 FPS, which is less ideal for fast-paced action.

Q: How does the GPU compare to its nearest rivals in synthetic benchmarks?

A: The RX 6750 XT has an average benchmark score of 26011. Its closest rival, the AMD Radeon R9 M395X, scores 25891, which is 0.5% slower. The NVIDIA GeForce RTX 3080 Ti Mobile scores 25740, putting it 1.1% behind the RX 6750 XT.

Q: What is the performance difference between Low and Ultra settings at 1440p?

Q: Does the CPU hold the system back at any point?

A: Benchmark results indicate the CPU is not a bottleneck. The Ryzen 7 7700 scores 1049 in the 3dMark single-thread test and 18760 in Cinebench R23 multicore, placing it in the 87th percentile of all CPUs. The high frame rates at 1080p Low (242 FPS) support this, showing the GPU is the limiting factor.

Q: What is the minimum FPS recorded in the measured data?

A: The only minimum FPS values provided are for the Medium preset at each resolution. At 1920x1080, the minimum is 179 FPS; at 2560x1440, it is 116 FPS; and at 3840x2160, it is 63 FPS. These figures suggest good frame pacing for the Medium preset.

GPU Role

The AMD Radeon RX 6750 XT is the dominant component in this pairing for Doom. The GPU’s specifications directly correlate with the measured performance drops as resolution increases. With a boost clock of 2600 MHz and a game clock of 2495 MHz, the card has substantial processing power, but its 12 GB of GDDR6 memory on a 192-bit bus (432.0 GB/s bandwidth) is a defining characteristic for high-resolution play.

The role of the GPU becomes clear when examining the frame rate scaling. The RX 6750 XT’s FP32 performance is rated at 13.31 TFLOPS, which is robust for a card in this class. However, the transition from 1440p to 4K results in a significant frame rate penalty across all settings. For example, at High settings, the average FPS drops from 115 to 62, a reduction of 46.1%. This indicates that the GPU’s compute units are saturated when rendering 4K resolutions.

The GPU’s VRAM capacity of 12 GB is adequate for Doom’s textures, even at 4K Ultra. There is no evidence in the data of texture swapping or memory-related stutters, as the minimum FPS for the Medium preset at 4K is 63. The card’s pixel rate of 166.4 GPixel/s and texture rate of 416.0 GTexel/s are sufficient to handle the game’s Vulkan-based renderer efficiently.

In synthetic benchmarks, the RX 6750 XT scores 20700 in Passmark G3D and 2548 in 3dMark Steel Nomad DX12. These scores place it in the 71st percentile of all GPUs, confirming its position as an upper-midrange part. The GPU’s performance relative to its nearest rivals is very tight, with a delta of only 0.5% to 1.1% from the scores of the Radeon R9 M395X, FirePro W7100, and RTX 3080 Ti Mobile. This suggests that in this specific benchmark suite, the card is well-matched against its peers, but in Doom, it is the clear bottleneck at higher resolutions.

How This Combo Ranks

The combination of the Ryzen 7 7700 and RX 6750 XT ranks 1696 out of 3712 tested combos in Doom. This places the pairing in the 54.3rd percentile of all systems tested, meaning it outperforms a slight majority of configurations. Given the CPU’s high percentile ranking (87th) and the GPU’s more modest one (71st), this combined rank is expected, as the overall performance is weighted by the less capable component.

The ranking suggests that this system is solidly mid-pack in the database. It is not an extreme high-end configuration, nor is it a low-end one. The CPU is clearly a top-tier part, as evidenced by its average benchmark score of 40081, which is nearly identical to its nearest rivals (AMD Ryzen AI 9 365 at 40048, Intel Core 5 221E at 40144). The GPU, however, drags the combo’s overall standing down slightly.

The delta between the CPU and GPU’s performance tiers is instructive. The Ryzen 7 7700 is only 0.6% slower than the Intel Core i9-13905H in average score, showing it can compete with mobile high-end parts. In contrast, the RX 6750 XT is only 1.1% faster than the RTX 3080 Ti Mobile, which is a laptop part. This mismatch suggests that the system is somewhat CPU-heavy for the GPU, but it does not result in a CPU bottleneck in Doom, as the frame rates are consistently high.

For users looking at this rank, it indicates a balanced system that should handle most games well. The 1696th position out of 3712 means there are many faster combos, but also many slower ones. The data shows that in Doom, the limiting factor is almost always the GPU, so any future upgrades should focus on that component.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the system’s capabilities across three resolutions and four settings presets.

At 1920x1080, the system is clearly GPU-limited at all presets. The Low preset achieves an average of 242 FPS, which is exceptionally high. The Medium preset averages 210 FPS, with a minimum of 179 FPS and a maximum of 242 FPS. High settings reduce the average to 178 FPS, and Ultra settings bring it down to 145 FPS. These results show that even at Ultra, the game is highly playable on a 144Hz monitor, and at lower settings, it can push beyond 240 FPS for competitive play.

At 2560x1440, the performance remains strong but shows the expected decline. Low settings average 156 FPS, which is still very high. Medium settings average 136 FPS, with a minimum of 116 FPS and a maximum of 157 FPS. High settings deliver 115 FPS on average, and Ultra settings drop to 94 FPS. The 1440p results indicate that the system is well-suited for this resolution, as all presets except Ultra maintain averages above 100 FPS.

At 3840x2160, the system starts to show its limits. Low settings average 85 FPS, which is playable. Medium settings average 74 FPS, with a minimum of 63 FPS and a maximum of 85 FPS. High settings average 62 FPS, which is just above the 60 FPS threshold for smooth gameplay. Ultra settings bring the average down to 51 FPS, which may be too low for some players in a fast-paced FPS. The 4K data shows that the GPU is the clear bottleneck, as the frame rates are much lower than at 1440p, even with the same settings.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on the target resolution and refresh rate.

For 1080p gaming, the Ultra preset is the best choice for visual fidelity, as it still maintains an average of 145 FPS. This is smooth on any 120Hz or 144Hz monitor. For players with 240Hz displays, the High preset at 178 FPS or even the Medium preset at 210 FPS would be better suited to maximize the refresh rate. The Low preset at 242 FPS offers the absolute highest frame rate, but the visual compromise may not be worth it for most users.

At 1440p, the High preset is the sweet spot, delivering 115 FPS on average. This is ideal for 120Hz monitors and offers a good balance between visual quality and performance. The Medium preset at 136 FPS is also excellent for those who prefer higher frame rates, while the Ultra preset at 94 FPS is still very playable on a 100Hz or 144Hz monitor, though it may not hit the maximum refresh rate consistently. The Low preset at 156 FPS is unnecessary unless the player is extremely sensitive to frame pacing.

For 4K gaming, the High preset is recommended, as it provides an average of 62 FPS, which is just above the 60 FPS target. The Medium preset at 74 FPS is a better option for those who want a safety margin above 60 FPS, as it also has a recorded minimum of 63 FPS. The Ultra preset at 51 FPS is not recommended for serious gameplay, as the frame rate can dip below 60 FPS, which is noticeable in a fast-paced shooter. The Low preset at 85 FPS is viable, but the visual downgrade is significant at this resolution.

Overall, the data suggests that the system is best utilized at 1440p with High or Medium settings, where it offers the best combination of high frame rates and visual quality. At 1080p, it is overkill for most situations, and at 4K, it requires settings compromises to maintain smooth performance.
