Doom

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 5080 is a formidable combination for Doom, and the measured frame rates confirm that this system is built for extreme performance. The data shows a configuration that not only clears the 60 FPS playability threshold at every resolution and preset tested but also delivers headroom typically reserved for high-refresh-rate displays. The benchmark results paint a picture of a system where the GPU is the primary driver of performance, yet the CPU's 12-core, 24-thread architecture with a boost clock of 5.60 GHz ensures no bottleneck at even the most demanding settings.

Measured FPS Breakdown

The measured FPS data for this combination is consistent across all tested resolutions, with average frame rates that scale predictably with both resolution and graphical preset. At 1920x1080, the system operates at exceptionally high frame rates, starting at a 426.2 average on Low settings and descending through 373.2 on Medium, 315.3 on High, and finally 257 on Ultra. This represents a 39.7% drop from the Low setting to the Ultra setting, indicating that the most demanding preset still leaves a massive performance cushion for monitors with refresh rates up to 240 Hz and beyond. The minimum and maximum FPS values are not provided in the data, but the sheer magnitude of the averages suggests that frame pacing is unlikely to be a concern in competitive scenarios.

Moving to 2560x1440, the average frame rates remain remarkably high, with 274.9 on Low, 239.2 on Medium, 203.2 on High, and 167.5 on Ultra. The performance delta between Low and Ultra at this resolution is 39.1%, closely mirroring the percentage drop seen at 1080p. This suggests that the GPU is still the limiting factor, as the resolution increase from 1080p to 1440p only reduces the average FPS by roughly 35% across all settings, which is consistent with the increased pixel count. The 167.5 average on Ultra at 1440p is particularly noteworthy, as it indicates the system can comfortably drive high-refresh-rate 1440p panels with all graphical features enabled.

At 3840x2160, the performance scales down further but remains far above the 60 FPS playability threshold. The Low preset yields an average of 152.2 FPS, which drops to 130.8 on Medium, 111 on High, and 89.8 on Ultra. The transition from 1440p to 4K results in a 45.7% reduction in average FPS on the Low preset, but the Ultra preset only sees a 46.4% reduction, showing a consistent scaling pattern. The 89.8 average on Ultra at 4K is still 29.8 FPS above the 60 FPS target, meaning that even the most demanding configuration tested provides a smooth and responsive experience. This data indicates that the RTX 5080, with its 16 GB of GDDR7 memory and 960.0 GB/s bandwidth, has ample headroom for this title.

Similar Performance Alternatives

Examining the nearest rivals for the CPU and GPU provides insight into what other hardware would behave similarly. The Ryzen 9 7900X has an average benchmark score of 53,288, with the closest rivals being the AMD EPYC 7313P (0.2% faster), the Intel Xeon Phi 7290 (0.3% slower), the Intel Xeon 634 (0.6% faster), and the Intel Core i7-14700F (0.6% slower). These processors are within a 0.6% performance delta of the 7900X, meaning that in a system with the same GPU, the frame rates in Doom would be nearly identical. For instance, swapping to the Intel Core i7-14700F would result in a negligible 0.6% average score difference, which would translate to less than 2 FPS difference at 1080p Ultra.

On the GPU side, the RTX 5080 has an average benchmark score of 56,083, with the AMD Radeon 8060S being 0.6% slower, the AMD Radeon RX 6750 GRE 12 GB being 0.7% slower, the AMD Radeon Pro W5700X being 2.3% slower, and the AMD Radeon RX 9070 GRE being 2.2% faster. The closest rival, the AMD Radeon 8060S, would deliver average frame rates that are within a few FPS of the RTX 5080 across all settings. It is important to note that these rival comparisons are based on average benchmark scores, not direct gaming measurements, but the small deltas suggest that a system with an RX 9070 GRE would be the closest performance match, potentially offering slightly higher frame rates in Doom.

For users considering alternative configurations, pairing any of the listed rival CPUs with the RTX 5080 would yield near-identical results, as would pairing the Ryzen 9 7900X with any of the rival GPUs. The data suggests that the performance envelope for this class of hardware is very tight, with the entire set of alternatives falling within a 2.3% performance band. This means that the gaming experience in Doom would be indistinguishable between any of these combinations, assuming the rest of the system is configured similarly.

Best Settings per Resolution

The data provides clear guidance for the best settings at each resolution, defined as the most demanding preset that maintains an average frame rate at or above 60 FPS. At 1920x1080, the Ultra preset is the best choice, delivering an average of 257 FPS. This is the highest quality setting available, and it still provides a frame rate that is over four times the playability threshold. The performance headroom at this resolution is so substantial that users could even enable additional anti-aliasing or supersampling without dropping below 60 FPS.

At 2560x1440, the Ultra preset remains the best option, with an average of 167.5 FPS. This represents a 34.8% reduction from the 1080p Ultra score, but it is still nearly three times the 60 FPS threshold. The system is clearly not challenged at this resolution, and users with 1440p 144 Hz monitors will be able to take full advantage of their display's refresh rate with all settings maxed out.

At 3840x2160, the Ultra preset is again the best setting, producing an average of 89.8 FPS. This is the only resolution where the frame rate drops below 100 FPS, but it still clears the 60 FPS threshold by a comfortable 29.8 FPS margin. The data indicates that even at 4K, the system has enough headroom to handle the most demanding scenes without dropping below playable levels. All four settings at all three resolutions produce average FPS values above 60, meaning that users have complete freedom to choose any preset based on their preferences for visual quality versus frame rate.

The Verdict

The verdict is unequivocal: this PC can run Doom exceptionally well at all tested resolutions and settings. The verdictByResolution data lists all four settings (Low, Medium, High, and Ultra) as playable at each of the three resolutions, with the best settings being Ultra at every resolution. The average FPS at the best settings is 257 at 1920x1080, 167.5 at 2560x1440, and 89.8 at 3840x2160. This means that the system clears the 60 FPS playability threshold by a minimum of 29.8 FPS, which is a significant margin that ensures smooth gameplay even during intense action sequences.

The data shows no weak points in this configuration. At 1080p, the system is capable of driving some of the highest refresh rate monitors available, with frame rates exceeding 400 on lower settings. At 1440p, it remains in high-refresh-rate territory even on Ultra, and at 4K, it still delivers a smooth experience that is well above the playability threshold. The Ryzen 9 7900X and RTX 5080 combination is clearly a top-tier pairing for this title, and the benchmark results indicate that users will not need to compromise on visual fidelity to achieve excellent performance.

CPU and GPU Roles

The division of labor between the CPU and GPU in Doom is clear from the scaling patterns in the measured FPS data. The GPU is the dominant factor, as evidenced by the significant frame rate reductions when moving from 1920x1080 to 3840x2160. At the Ultra preset, the average FPS drops from 257 to 167.5 to 89.8 as resolution increases, which is a 65.1% reduction from 1080p to 4K. This scaling is consistent with the GPU having to render 4 times as many pixels at 4K compared to 1080p, and the fact that the frame rate does not drop by exactly 75% indicates that the CPU is providing some assistance at lower resolutions.

The CPU's role becomes more apparent at lower resolutions where frame rates are extremely high. At 1080p Low, the system achieves 426.2 FPS, which requires the CPU to process a massive number of draw calls and game logic updates. The Ryzen 9 7900X, with its 12 cores and 24 threads, is well-suited for this task, and its single-thread performance of 2617 on Geekbench ensures that it can keep up with the GPU's output. The data shows that the CPU is not a bottleneck at any resolution, as the frame rates scale smoothly with resolution changes.

The relative importance of each component shifts with resolution. At 1080p, the CPU plays a more significant role because the GPU can produce frame rates that approach the CPU's processing limits. At 4K, the GPU becomes the clear bottleneck, as the frame rates drop to levels where the CPU has more headroom. This is a typical pattern for high-refresh-rate gaming, and the data confirms that the RTX 5080 is the component that determines the system's performance ceiling at higher resolutions, while the Ryzen 9 7900X ensures that the system can achieve its maximum potential at lower resolutions.
