Doom

The Intel Core i7-12700KF and AMD Radeon RX 9070 combination delivers a masterclass in high-refresh-rate gaming for Doom, with benchmark results indicating the GPU is the primary scaling factor as resolution increases. At 1080p, the combo achieves exceptional frame rates, with the Low preset hitting 293.5 FPS and the Ultra preset still producing a highly playable 178.8 FPS. Moving to 1440p, the performance remains stellar, with the Low preset at 192.3 FPS and Ultra at 114.4 FPS, showing a predictable and smooth scaling curve. However, the transition to 4K reveals a significant bottleneck shift. At 3840x2160, the Ultra preset drops to 62.2 FPS, and even the Low preset, which yields 102.5 FPS, demonstrates that the rendering load has increased substantially. The performance drop from 1080p Low to 4K Low is a steep 65.1% reduction, while the drop from 1080p Ultra to 4K Ultra is a less severe 65.2% decline. This data suggests that while the CPU is capable of feeding the GPU at lower resolutions, the Radeon RX 9070 becomes the limiting component at 4K, particularly with higher graphical fidelity settings.

Resolution Scaling

The FPS scaling from 1080p to 4K clearly identifies the AMD Radeon RX 9070 as the bottleneck at higher resolutions. At 1080p, the combo is likely CPU-bound or at least balanced, as evidenced by the massive frame rates that exceed 200 FPS on most presets. The i7-12700KF's strong single-thread performance keeps the GPU fed, allowing it to stretch its legs. However, the data shows a pronounced drop in performance as pixel count increases. For instance, with High settings, the average frame rate falls from 217.2 FPS at 1080p to 143.3 FPS at 1440p, a 34% reduction, and then further to 76.5 FPS at 4K, a 46.6% reduction from the 1440p figure. This progressive decline is characteristic of a GPU-limited scenario where the rendering pipeline can no longer maintain the same throughput. The 4K Ultra result of 62.2 FPS is particularly telling; while still playable, it represents a 65.2% drop from the 1080p Ultra score of 178.8 FPS. This data confirms that for users targeting 4K, the GPU's raw pixel-pushing power, with its 16 GB of GDDR6 memory and 256-bit bus, is the determining factor for performance, rather than the CPU's core count or clock speed.

How This Combo Ranks

In the broader context of tested hardware combinations, this pairing of the Core i7-12700KF and Radeon RX 9070 performs exceptionally well for Doom. The data places this specific combo at rank 558 out of 1681 tested combinations, positioning it in the top third of all systems. This ranking is a strong indicator of the synergy between these two components. The CPU itself holds an 89th percentile ranking against all tested CPUs, and while the GPU's 79th percentile is slightly lower, the combination's overall rank suggests that the high-frequency, 12-core processor is more than adequate to support the graphics card's capabilities in this title. The performance is not necessarily about being the absolute fastest, but about the balance that prevents the CPU from holding back the GPU. Given that the game is an older title, the data suggests this combo is likely overkill for 1080p but hits a sweet spot for high-refresh-rate 1440p gaming, offering a significant performance buffer that ensures smooth gameplay even in demanding scenes.

CPU Role

The Intel Core i7-12700KF's specifications provide ample headroom for Doom's engine. With 12 cores and 20 threads, the CPU has significant parallel processing capability, though the game's performance is more reliant on single-core speed. The processor's base clock of 3.60 GHz and boost clock of 5.00 GHz are the key drivers here. Benchmark results show a single-thread score of 1043 in 3DMark and a Geekbench single-core score of 2526, which are strong indicators of the per-core performance needed to maintain high frame rates. The data shows that at 1080p, where the CPU is more likely to be the limiting factor, the combo still achieves 217.2 FPS on High settings and 293.5 FPS on Low, demonstrating that the CPU's 5.00 GHz boost clock is more than sufficient to handle the game's logic and draw calls. The 25 MB of shared L3 cache also helps in keeping frequently accessed data close to the cores. While the CPU's multi-threaded capabilities are impressive, with a Cinebench R23 multi-core score of 28979, the game's performance at higher resolutions shows that the GPU, not the CPU, becomes the bottleneck, confirming the processor's role as a stable, high-performance foundation.

GPU Role

The AMD Radeon RX 9070 is the driving force behind the high-resolution performance in Doom. Its specifications, including a boost clock of 2520 MHz and a game clock of 2070 MHz, provide the raw throughput needed for high frame rates. The GPU's 16 GB of GDDR6 memory on a 256-bit bus with a bandwidth of 644.6 GB/s ensures that textures and geometry are fed to the cores without stuttering. The data clearly shows the GPU's influence scaling with resolution. At 1080p, the GPU is not fully taxed, but as the resolution increases to 1440p and 4K, the frame rates drop correspondingly, which is the expected behavior for a GPU-bound scenario. The 4K results, ranging from 62.2 FPS on Ultra to 102.5 FPS on Low, demonstrate the GPU's ability to handle the game at high fidelity. While the GPU's average benchmark score of 34780 places it in the 79th percentile, its performance in this specific title is excellent, suggesting that the RDNA 4.0 architecture is well-optimized for the game's Vulkan-based engine.

Settings Recommendations

For the optimal balance of visual quality and performance, the High preset at 1440p is the recommended starting point, as it delivers 143.3 FPS. This frame rate is ideal for 144Hz monitors and provides a significant visual upgrade over the Medium preset. If a player has a standard 60Hz display, the Ultra preset at 4K, averaging 62.2 FPS, is a viable choice for maximum fidelity. For competitive play where frame rate is king, the Low preset at 1080p, hitting 293.5 FPS, or at 1440p with 192.3 FPS, offers the smoothest possible experience. The data shows that the Medium preset provides a good middle ground, but the performance jump from Medium to High is substantial enough (from 168.7 FPS to 143.3 FPS at 1440p) to justify the visual upgrade. At 4K, the Medium preset at 92.3 FPS is a better choice than High (76.5 FPS) if the user wants to stay above 90 FPS, while the Ultra preset is for those who prioritize visuals over frame rate.
