Doom

The AMD Ryzen 7 9700X and AMD Radeon RX 7900 XTX combination delivers exceptional performance in Doom, with the benchmark data showing a system capable of obliterating even the most demanding settings at high resolutions. This pairing of a modern 8-core Zen 5 processor with a flagship RDNA 3 graphics card results in a machine that consistently produces frame rates well beyond the range of standard high-refresh-rate gaming, making it a top-tier choice for this classic FPS.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 9700X is built on the Zen 5 architecture and features 8 cores and 16 threads. Its base clock is 3.80 GHz, which can boost up to 5.50 GHz. This high boost clock is critical for a game like Doom, which is known for its fast-paced action and responsiveness. The processor’s performance in single-threaded and lightly-threaded workloads is particularly relevant. In synthetic benchmarks, the 9700X scores 1280 in 3dmark_single_thread and 4459 in cinebench_r23_singlecore, demonstrating its strong per-core capabilities.

The data indicates that this CPU is not a bottleneck in most scenarios. With a TDP of 65 watts and a 32 MB shared L3 cache, the 9700X provides ample processing power. Its performance in multi-threaded tests, such as a 31588 score in cinebench_r23_multicore, further confirms its ability to handle any background tasks while gaming. The processor is part of the 9000 series and uses the AMD Socket AM5 platform. Its 89th percentile ranking among all CPUs shows that it is significantly more powerful than the majority of processors available. In the context of Doom, this means the CPU can easily feed the GPU with geometry and draw calls, allowing the graphics card to be the primary determinant of frame rates, especially at higher resolutions.

The combo rank of 239 reflects how well this specific CPU and GPU work together in Doom, producing a highly capable gaming system.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data shows a clear trend when scaling resolution from 1920x1080 to 3840x2160. At 1080p with Low settings, the system achieves 364.8 FPS. This drops to 234.6 FPS at 1440p and further to 127.4 FPS at 4K. This pattern is consistent across all settings. The frame rate drop from 1080p to 4K is significant, with the 4K Low result being only 34.9% of the 1080p Low result. This dramatic scaling indicates that the system is becoming increasingly GPU-bound at higher resolutions.

At 1080p, the CPU is likely keeping up well, allowing the GPU to push extremely high frame rates. The gap between the 1080p Low (364.8 FPS) and 4K Low (127.4 FPS) is 237.4 FPS, which highlights the massive workload increase on the GPU at 4K. As the resolution increases, the pixel rendering workload on the Radeon RX 7900 XTX grows exponentially, making it the primary limiting component. The Ryzen 7 9700X's strong single-core performance ensures that it does not become a bottleneck until frame rates reach extremely high levels, which are mostly seen at 1080p. The data suggests that for maximum frame rates, 1080p is the target, but the system is still very capable of delivering high refresh rates at 1440p and 4K.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive look at the system's performance across different resolutions and settings. At 1920x1080, the system delivers outstanding results. With Low settings, it achieves 364.8 FPS. Moving to Medium settings, the average FPS is 315.5. High settings produce 270.4 FPS, and the most demanding Ultra preset still yields a very high 217.5 FPS. These numbers show that at 1080p, the system is capable of driving even the fastest high-refresh-rate monitors in any setting.

At 2560x1440, performance remains excellent. The Low preset sees an average of 234.6 FPS. Medium settings follow at 206.1 FPS, and High settings at 175.8 FPS. The Ultra preset at 1440p delivers 144.9 FPS, which is still incredibly smooth and well above the threshold for high-refresh-rate gaming. This resolution provides a great balance between visual fidelity and performance.

At 3840x2160, the system still delivers very playable frame rates. The Low preset achieves 127.4 FPS. Medium settings drop to 110.6 FPS, and High settings to 96.3 FPS. The Ultra preset at 4K is the most demanding, producing 74.4 FPS. This is still an excellent result for 4K gaming, showing the RX 7900 XTX's ability to handle this resolution well, though users targeting 4K Ultra may want to consider adjusting settings to maintain higher frame rates. The data shows a consistent performance hierarchy across all resolutions, with Low being the fastest and Ultra being the slowest.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 7900 XTX is the primary driver of frame rates in this system, especially at higher resolutions. It is based on the RDNA 3.0 architecture and features a massive 24 GB of GDDR6 memory on a 384-bit bus, providing a bandwidth of 960.0 GB/s. This large memory capacity is more than sufficient for a game like Doom, even at 4K Ultra settings, and ensures there are no texture streaming or memory-related stutters. The GPU's base clock is 1929 MHz, with a boost clock of 2498 MHz and a game clock of 2365 MHz.

The GPU's raw compute power is substantial. It features 6144 shading units, 384 TMUs, and 192 ROPs. Its FP32 performance is rated at 61.39 TFLOPS. These specifications translate directly to the high frame rates seen in the measured data. The GPU's 85th percentile ranking versus all GPUs confirms that it is a top-tier performer. Its nearest rivals in benchmarks include the NVIDIA GeForce RTX 4070 Ti, which is 2% behind, and the NVIDIA GeForce RTX 4090 Mobile, which is 0.8% ahead. The 24 GB VRAM buffer is a key asset, providing headroom for future titles and high-resolution textures. In Doom, its role is clear: it is the component that determines the final frame rate, with its performance scaling directly with the resolution and settings applied.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the best settings depend on the user's display and performance targets. For users with a 1080p monitor, all presets are viable, but the Ultra preset at 217.5 FPS provides the best visual experience while still delivering a frame rate that far exceeds any standard display's refresh rate. The High preset at 270.4 FPS is also a great choice if users prefer even higher frame rates for competitive play. Given the massive headroom at this resolution, there is no reason to drop below High settings.

For 1440p, the Ultra preset at 144.9 FPS is the recommended choice for a balanced experience, offering excellent visuals and a frame rate that is perfect for high-refresh-rate monitors (144Hz and above). The High preset at 175.8 FPS is an even better option for those with 165Hz or 240Hz displays, as the performance gain is significant while the visual difference between High and Ultra is often minimal. The data shows that High settings at 1440p offer an excellent compromise between visual quality and performance.

At 4K, the High preset at 96.3 FPS is the most balanced recommendation for a smooth experience on a 60Hz or 120Hz display. The Medium preset at 110.6 FPS provides a further boost for those seeking higher frame rates. The Ultra preset at 74.4 FPS is playable but may feel less fluid on high-refresh-rate displays. For 4K gaming, dropping from Ultra to High yields a 29.4% performance increase, making it the most practical choice for a consistently smooth experience. In summary, the data suggests that High settings are the sweet spot across all resolutions, delivering a strong balance of visual fidelity and high frame rates, while Ultra is only recommended for 1080p and 1440p users with high-refresh-rate monitors.
