Doom

The AMD Ryzen 7 9700X and AMD Radeon RX 7900 XT combination delivers a remarkably consistent experience in Doom, with the data showing a clear progression from 1080p to 4K where the GPU becomes the primary constraint. At 1080p, the combo achieves a 336.9 FPS average on Low settings, which drops to 201.9 FPS on Ultra, indicating a substantial performance ceiling that favors high-refresh-rate displays. Moving to 1440p, the averages range from 221.4 FPS on Low to 130.6 FPS on Ultra, while 4K sees the most significant scaling pressure, with the Ultra preset producing a 70.3 FPS average and High settings reaching 86 FPS. The 117.3 FPS average at 4K Low demonstrates that even at the highest resolution, the hardware can maintain playable framerates when settings are reduced, though the gap between 1080p and 4K at Ultra (201.9 vs 70.3 FPS) highlights the GPU-bound nature of the title at higher resolutions.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and tells a clear story about where the bottleneck lies. At Ultra settings, the average framerate declines from 201.9 FPS at 1920x1080 to 130.6 FPS at 2560x1440, a 35.3% reduction, and then to 70.3 FPS at 3840x2160, representing a 65.2% drop from the 1080p baseline. This pattern is consistent across all settings presets, with the Low preset showing a similar trajectory: 336.9 FPS at 1080p, 221.4 FPS at 1440p, and 117.3 FPS at 4K. The scaling behavior indicates that the RX 7900 XT's 20 GB of GDDR6 memory and 800.0 GB/s bandwidth are sufficient to feed the renderer, but the raw compute throughput—51.48 TFLOPS FP32—becomes the limiting factor as pixel count quadruples from 1080p to 4K. The 70.3 FPS average at 4K Ultra suggests that for competitive play, users should either drop to High settings (86 FPS) or accept a lower preset to maintain frame times above the 60 FPS threshold. The data also reveals that the CPU, with its 8 cores and 16 threads, is not the constraint at any resolution, as the framerate differences between 1080p and 1440p are proportionally similar to the pixel count increase, indicating pure GPU scaling.

FAQ

CPU Role

The AMD Ryzen 7 9700X, built on the Zen 5 architecture and 4 nm process, brings 8 cores and 16 threads to the table, with a base clock of 3.80 GHz and a boost clock of 5.50 GHz. In Doom, this processor demonstrates its capability through the measured results, particularly at 1080p where the framerate ceiling is not constrained by the GPU. The 336.9 FPS average at 1080p Low is a direct indicator of the CPU's ability to feed the renderer, as the RX 7900 XT is not fully taxed at these settings. The 3DMark single-thread score of 1280 and Passmark single-thread score of 4654 suggest that the CPU's per-core performance is sufficient for the game's engine, which benefits from the high clock speeds. The L3 cache of 32 MB (shared) and L2 cache of 1 MB per core provide low-latency access to frequently used data, which is critical for maintaining consistent frame times in fast-paced FPS titles. The Cinebench R23 multicore score of 31588 indicates that even if Doom were to utilize more threads, the CPU has headroom, but the data shows that 8 cores are more than adequate for this title, as evidenced by the 130.6 FPS at 1440p Ultra, which is still GPU-bound.

How This Combo Ranks

The combo's rank of 375 out of 1681 tested combinations places it in the 77.7th percentile of all systems tested for Doom, which is a strong showing but not at the very top. This ranking reflects the balance between the Ryzen 7 9700X and the RX 7900 XT, where the GPU's 82nd percentile ranking (versus all GPUs) and the CPU's 89th percentile (versus all CPUs) combine to produce a system that excels at high framerates but is not the absolute fastest. The nearest rival for the GPU, the NVIDIA GeForce RTX 5080 Mobile, has a deltaPct of 0.0, indicating that the RX 7900 XT is essentially tied with a top-tier mobile GPU in synthetic benchmarks, yet in Doom, the desktop advantage of the 7900 XT's 800.0 GB/s memory bandwidth shows through in the 4K results. Similarly, the CPU's nearest rival, the Intel Core i5-14500HX, is only 0.2% ahead in average benchmark score, but the Ryzen 7 9700X's higher boost clock (5.50 GHz vs. the mobile part's unspecified clocks) likely contributes to the strong 1080p results. The 375th rank is respectable, but the data suggests that systems with faster GPUs, such as those with higher FP32 throughput, would rank higher, particularly at 4K where the GPU is the clear bottleneck.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best performance, with all settings presets exceeding 200 FPS. The Low preset averages 336.9 FPS, Medium drops to 294.6 FPS, High yields 248.9 FPS, and Ultra produces 201.9 FPS. These numbers indicate that at 1080p, the user has complete flexibility to prioritize either visual fidelity or raw framerate, with even the Ultra preset maintaining a 201.9 FPS average that exceeds the refresh rate of most monitors. Moving to 2560x1440, the performance scales proportionally: Low averages 221.4 FPS, Medium 190.2 FPS, High 162.5 FPS, and Ultra 130.6 FPS. This resolution is the sweet spot for high-refresh-rate gaming, as even Ultra settings remain above 130 FPS. At 3840x2160, the results show the GPU's limits: Low averages 117.3 FPS, Medium 102.9 FPS, High 86 FPS, and Ultra 70.3 FPS. The 4K Ultra result of 70.3 FPS is just above the 60 FPS threshold, but the 86 FPS at High suggests that users with 4K 120Hz displays should choose High settings to avoid frame drops. The data also shows a consistent pattern across all resolutions: the gap between Low and Medium is smaller than the gap between High and Ultra, indicating that the Ultra preset imposes a significant rendering cost that may not be visually justified.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. For 1080p displays with 240Hz refresh rates, the High preset (248.9 FPS) or even Ultra (201.9 FPS) is recommended, as both exceed 200 FPS and provide excellent visual quality. For 1440p monitors with 144Hz refresh rates, the High preset (162.5 FPS) is the best choice, as it maintains a framerate above the refresh rate while offering better visuals than Medium (190.2 FPS) at a modest performance cost. The Ultra preset at 1440p (130.6 FPS) is still viable for 120Hz displays, but the 24.4% advantage of High over Ultra suggests that most users will not notice the visual difference. For 4K displays, the recommendation is clear: use the High preset (86 FPS) rather than Ultra (70.3 FPS), as the 22.4% framerate improvement is more beneficial for gameplay smoothness than the marginal visual upgrade. The Low preset at 4K (117.3 FPS) is only recommended for users with 120Hz 4K displays who prioritize framerate over all else, but the Medium preset (102.9 FPS) offers a better balance for most users. In all cases, the data shows that High settings provide the best experience-to-performance ratio, making it the default recommendation for this hardware combination.

GPU Role

The AMD Radeon RX 7900 XT, based on the RDNA 3.0 architecture and 5 nm process, is the primary driver of Doom's performance at higher resolutions. With 20 GB of GDDR6 memory on a 320-bit bus, the GPU delivers 800.0 GB/s of memory bandwidth, which is crucial for the texture-heavy environments of Doom. The 5376 shading units and 192 ROPs enable a pixel rate of 459.6 GPixel/s, allowing the GPU to handle the game's fast-paced action without stutter. The boost clock of 2394 MHz and game clock of 2025 MHz provide the compute throughput needed for the 51.48 TFLOPS FP32 performance, which is evident in the 4K results where the GPU is fully utilized. The 336 texture mapping units and 804.4 GTexel/s texture rate ensure that the game's detailed surfaces are rendered without bottlenecking. The GPU's 82nd percentile ranking versus all GPUs, with a Passmark G3D score of 29009, confirms its high-end status, and the nearest rival, the NVIDIA GeForce RTX 5080 Mobile, shows a deltaPct of 0.0, indicating they are evenly matched in synthetic benchmarks. However, in Doom, the 7900 XT's desktop-class power envelope (300 W TDP) and dedicated 20 GB VRAM allow it to maintain higher sustained clocks, which is reflected in the 4K Ultra result of 70.3 FPS. The GPU's role as the limiting factor is clear from the resolution scaling data, as the CPU's performance remains constant while the GPU's workload increases with pixel count.
