Doom

The AMD Ryzen 7 7700X paired with the AMD Radeon RX 6750 XT delivers a highly capable 1440p experience in Doom, but the data clearly shows that 4K Ultra is the only setting where this combination struggles to maintain playable frame rates. The benchmark results indicate a system that is firmly GPU-limited at higher resolutions, while the CPU’s strong single-thread performance ensures high frame rates at 1080p.

Resolution Scaling

The measured FPS data reveals a predictable and steep performance drop as resolution increases, confirming that the Radeon RX 6750 XT is the primary bottleneck at 4K. At 1080p with Low settings, the combo achieves an average of 241.3 FPS, which drops to 157.3 FPS at 1440p and further to 85.1 FPS at 4K. This represents a 35% reduction from 1080p to 1440p and a 46% reduction from 1440p to 4K, showing that the GPU’s pixel throughput is the limiting factor.

The scaling pattern becomes more pronounced at higher settings. With Ultra settings, the average frame rate falls from 144 FPS at 1080p to 95.3 FPS at 1440p, and then to 49.9 FPS at 4K. The drop from 1440p to 4K at Ultra is a massive 48%, indicating that the 12 GB of GDDR6 memory and the GPU’s compute resources are saturated. The data suggests that 1080p and 1440p are fully playable across all settings, but 4K requires dropping to Medium settings, which yields 73.3 FPS, to stay above the 60 FPS threshold.

How This Combo Ranks

In the overall database of tested CPU and GPU combinations, this pairing ranks 831 out of 1681 combos for Doom, placing it in the upper half of all configurations. This rank reflects a balanced setup where the Ryzen 7 7700X’s capabilities are well-matched to the RX 6750 XT’s performance envelope. The combo’s percentile placement suggests that it outperforms a majority of tested systems, though it is not among the elite high-end configurations.

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

A: At 1080p, the difference is 97.3 FPS, with Low achieving 241.3 FPS and Ultra achieving 144 FPS. At 4K, the gap widens to 35.2 FPS, with Low at 85.1 FPS and Ultra at 49.9 FPS, showing that Ultra settings place a significant load on the GPU.

Q: How does this combo compare to its nearest rivals?

A: The CPU outperforms the Intel Core i5-13500 by 0.4% in average benchmark scores, while the GPU is 0.2% ahead of the AMD Radeon RX 5600M. This indicates the combo is closely matched with its direct competitors.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across three resolutions and four settings presets. At 1920x1080, the combo achieves its highest frame rates: 241.3 FPS on Low, 211.2 FPS on Medium, 177.2 FPS on High, and 144 FPS on Ultra. These numbers show that even at the most demanding settings, the system never dips below 144 FPS, making 1080p an effortless resolution for this hardware.

Moving to 2560x1440, the performance remains strong but shows the GPU’s workload increasing. Low settings produce 157.3 FPS, Medium delivers 134.8 FPS, High reaches 116.2 FPS, and Ultra drops to 95.3 FPS. The gap between Low and Ultra at this resolution is 62 FPS, which is a significant spread that highlights the impact of graphical fidelity on the GPU.

At 3840x2160, the results are more varied. Low settings yield 85.1 FPS, Medium drops to 73.3 FPS, High falls to 62.9 FPS, and Ultra bottoms out at 49.9 FPS. The difference between Low and Ultra at 4K is 35.2 FPS, and it is the only resolution where Ultra settings fail to reach 60 FPS. The data shows that 4K gaming is possible, but only with careful settings management.

CPU Role

The AMD Ryzen 7 7700X is a Zen 4 architecture processor with 8 cores and 16 threads, running at a base clock of 4.50 GHz and a boost clock of 5.40 GHz. Its benchmark performance is strong, with a Cinebench R23 multi-core score of 30325 and a single-core score of 4281, indicating excellent all-around capability. In Doom, a game that benefits from high single-thread performance, the CPU’s 3DMark single-thread score of 1090 ensures that it can feed the GPU efficiently at lower resolutions.

The CPU’s 32 MB of shared L3 cache and support for DDR5 memory with a bandwidth of 83.2 GB/s provide ample data throughput for game logic and asset streaming. At 1080p, where the GPU is not the bottleneck, the CPU’s performance is the deciding factor, and the data shows it is more than adequate, as evidenced by the 241.3 FPS result at Low settings. The processor’s 89th percentile ranking among all CPUs, and its 0.4% lead over the Intel Core i5-13500, confirm that it is a top-tier gaming processor.

Settings Recommendations

For the best balance of visual quality and performance, the data strongly recommends 1440p with High settings. This configuration delivers an average of 116.2 FPS, which is well above the 60 FPS threshold and provides a smooth, responsive experience. The jump from Medium to High at 1440p is 18.6 FPS, a noticeable improvement, while the jump from High to Ultra is 20.9 FPS, which may not justify the visual gains for all users.

If 4K is the target, Medium settings are the only viable option, yielding 73.3 FPS. High settings at 4K drop to 62.9 FPS, which is still playable but leaves little headroom for demanding scenes. Ultra settings at 4K should be avoided, as the 49.9 FPS average falls below the 60 FPS threshold and may result in noticeable stuttering. At 1080p, all settings are playable, but Ultra at 144 FPS is the most visually impressive option without sacrificing smoothness.

GPU Role

The AMD Radeon RX 6750 XT is a RDNA 2.0 architecture GPU with 2560 shading units, 160 TMUs, and 64 ROPs. It operates at a base clock of 2150 MHz and a boost clock of 2600 MHz, with 12 GB of GDDR6 memory on a 192-bit bus providing 432.0 GB/s of bandwidth. The GPU’s FP32 performance of 13.31 TFLOPS and its 79th percentile ranking among all GPUs indicate it is a solid mid-range performer.

The GPU’s memory configuration is sufficient for Doom’s textures at 1440p, but the data shows it becomes a limiting factor at 4K Ultra. The frame rate drop from 95.3 FPS at 1440p Ultra to 49.9 FPS at 4K Ultra is a 48% reduction, which is consistent with the GPU’s pixel rate of 166.4 GPixel/s being overwhelmed by the 4K resolution. The RX 6750 XT’s 0.2% lead over the AMD Radeon RX 5600M in average benchmark scores shows it is competitive, but its performance in Doom is ultimately constrained by its memory bandwidth and compute units.
