Doom

This combo pairs the 12-core AMD Ryzen 9 7900X with the NVIDIA GeForce RTX 4080 SUPER, and the measured frame rates in Doom show a system that is overwhelmingly GPU-limited at higher resolutions, yet still capable of extreme refresh rates at 1080p. The data indicates this pairing ranks 94th out of 1681 tested combos in this game, placing it in the top 6% of all configurations. The results across the three resolutions and four quality presets paint a clear picture of where the bottlenecks lie and how to best configure the game for your display.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial and reveals the expected scaling behavior for a high-end GPU. At Ultra settings, the average FPS falls from 241.2 at 1920x1080 to 154.7 at 2560x1440, then further to 85.9 at 3840x2160. This represents a 64% reduction in average FPS when moving from 1080p to 4K at Ultra, showing that the RTX 4080 SUPER is the primary limiting factor at higher pixel counts.

The pattern holds across all quality presets. At Low settings, the system delivers 399.6 FPS at 1080p, dropping to 259.8 at 1440p, and then to 143.2 at 4K. The 4K Low result is actually lower than the 1080p Ultra result (143.2 vs 241.2), which confirms that resolution has a more significant impact on performance than quality settings in this title. Similarly, at Medium settings, the 4K average of 121.4 FPS is nearly identical to the 1080p Ultra average of 241.2 FPS being halved.

This scaling behavior indicates that Doom is highly sensitive to pixel count. The data suggests that at 1080p, the CPU has more headroom, as the Ryzen 9 7900X can feed frames fast enough to exceed 300 FPS on Low and Medium presets. At 4K, however, the GPU becomes the clear bottleneck, with the difference between Low and Ultra settings (143.2 vs 85.9 FPS) being a 40% performance swing. For 1440p users, the system still provides excellent headroom, with even the most demanding Ultra preset maintaining an average above 150 FPS.

GPU Role

The RTX 4080 SUPER features 16 GB of GDDR6X memory on a 256-bit bus, providing 736.3 GB/s of bandwidth. This memory configuration is directly relevant to Doom’s results, as the game’s texture-heavy environments benefit from the capacity and bandwidth. The GPU’s boost clock of 2550 MHz, paired with its 10240 shading units, delivers the raw compute necessary for the high frame rates observed in the measured data.

The GPU’s performance relative to its nearest rivals shows it is well-positioned. The benchmark data lists the RTX 4080 SUPER with an average benchmark score of 53610, which is 0.2% ahead of the AMD Radeon RX 6900 XT (53489) and 0.4% ahead of the AMD Radeon Pro W6600M (53414). The deltaPct values indicate that the RTX 4080 SUPER leads these rivals by a narrow margin. However, it trails the NVIDIA GeForce RTX 5070 Ti by 2.9%, suggesting that newer generation GPUs offer a step up in raw compute.

In Doom specifically, the GPU’s role is most evident at 4K. The difference between 4K Low (143.2 FPS) and 4K Ultra (85.9 FPS) is 57.3 FPS, which is a massive gap that can only be attributed to the GPU’s shader and memory throughput limits. The fact that the GPU can maintain 103.6 FPS at 4K High demonstrates that it has enough headroom for a playable experience at the highest resolution, but users chasing 120+ FPS at 4K will need to compromise on quality settings.

Settings Recommendations

Based on the measured rows, the High preset offers the most balanced experience across all resolutions. At 4K, High delivers 103.6 FPS, which is comfortably above the 60 FPS threshold for smooth gameplay and only 17.8 FPS less than the Medium preset (121.4 FPS). The jump from High to Ultra at 4K costs 17.7 FPS (from 103.6 to 85.9), which is a 17% performance penalty for what is likely a marginal visual gain in a fast-paced FPS.

For 1440p displays, the High preset is the clear recommendation, delivering 189.1 FPS. This is well above the 144 Hz refresh rate that many 1440p monitors support, and it still leaves headroom for future driver optimizations. The Ultra preset at 1440p (154.7 FPS) is also viable for 144 Hz displays, but the 34.4 FPS drop from High to Ultra suggests that High is the more efficient choice.

At 1080p, the Low preset (399.6 FPS) is only relevant for competitive players with 360 Hz displays. For most users, the High preset at 296.8 FPS is more than sufficient, providing nearly double the frame rate of a standard 144 Hz display. The Medium preset at 345.9 FPS offers a middle ground, but the data shows that High is the sweet spot for visual fidelity without sacrificing performance. In summary, High is the recommended preset for all resolutions, with Ultra reserved for users who prioritize visuals over frame rate at 1440p or below.

FAQ

How This Combo Ranks

This specific configuration of the Ryzen 9 7900X and RTX 4080 SUPER ranks 94th out of 1681 tested combos in Doom, placing it in the top 5.6% of all systems tested. This is a strong result, but it is not at the absolute top, indicating that there are faster combinations available, likely featuring newer GPUs or higher-end CPUs.

The CPU’s own ranking provides context. The Ryzen 9 7900X holds the 93rd percentile among all CPUs tested, with an average benchmark score of 50556. Its nearest rival, the Intel Core Ultra 5 235, scores 50598, which is only 0.1% higher. The AMD Ryzen 9 5900XT scores 50738 (0.4% higher), and the Intel Core i7-13850HX scores 50827 (0.5% higher). This shows that the CPU is competitive but not leading its class.

The GPU’s 88th percentile ranking among all GPUs is slightly lower than the CPU’s, and its average score of 53610 places it just above the AMD Radeon RX 6900 XT. The combo’s overall rank of 94 suggests that the pairing is well-balanced, with neither component holding the other back significantly. The fact that this combo outperforms 94% of all tested systems in Doom indicates that it is a high-end configuration, but the remaining 6% of combos likely feature newer hardware that pushes frame rates even higher.

CPU Role

The Ryzen 9 7900X brings 12 cores and 24 threads to this pairing, with a base clock of 4.70 GHz and a boost clock of 5.60 GHz. This Zen 4 architecture, built on a 5 nm process, provides the single-threaded performance that Doom’s engine relies on. The CPU’s Cinebench R23 multicore score of 43695 and single-core score of 6168 indicate strong all-around performance, and its 64 MB of shared L3 cache helps reduce memory latency in gaming workloads.

In Doom, the CPU’s role becomes more apparent at lower resolutions. At 1080p Low, the system delivers 399.6 FPS, which is close to the practical limit for many displays. The fact that the 1080p Ultra result (241.2 FPS) is significantly lower than the 1080p Low result suggests that the GPU is still the limiting factor even at this resolution, as the CPU has enough headroom to feed frames at higher rates.

The CPU’s 3DMark scores further illustrate its capability. The single-thread score of 1093 and the max-thread score of 12536 show that the CPU scales well with additional threads, but Doom is not a heavily threaded title. The 2-thread score of 2137 and 4-thread score of 4151 indicate that the CPU’s performance on fewer threads is sufficient for this game’s demands. Given that the CPU ranks in the 93rd percentile overall, it is not the bottleneck in this combo, even at 1080p where the GPU is pushed to its limits. The data confirms that the Ryzen 9 7900X provides ample processing power for Doom, allowing the RTX 4080 SUPER to operate at its full potential across all tested settings.
