Doom

The Intel Core i5-11400F and AMD Radeon RX 6750 XT combination delivers a formidable Doom experience, placing in the 828th position out of 1681 tested combos. This pairing of a 6-core, 12-thread Rocket Lake processor with a 12 GB RDNA 2.0 graphics card produces frame rates that range from the highly competitive at 1080p to the merely playable at 4K Ultra. The data reveals a system where the GPU is the primary driver of performance scaling, while the CPU provides a robust foundation that rarely becomes the limiting factor.

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor based on the Rocket Lake architecture, built on Intel's 14 nm process. It operates with a base clock of 2.60 GHz and a boost clock of 4.40 GHz, supported by a 12 MB shared L3 cache. In the context of Doom, a title known for its id Tech engine, this CPU configuration provides ample headroom. The processor's multi-threaded capabilities are reflected in a Cinebench R23 multicore score of 14372, while its single-thread performance is represented by a score of 2029 in the same test. These figures indicate a balanced processor that can handle the game's physics and AI calculations without bottlenecking the graphics card.

The benchmark results across different resolutions show that the CPU's influence is most pronounced at lower resolutions where frame rates are exceptionally high. At 1920x1080 with Low settings, the combo achieves 238.9 FPS, a figure that suggests the CPU is working near its limits to feed the GPU. However, the processor's performance metrics place it in the 75th percentile against all CPUs, with an average benchmark score of 17181. This places it in close competition with the AMD Ryzen 7 5700U, which has an average score of 17189, and the Intel Core i7-1260P at 17212. The data indicates that the i5-11400F is a capable partner for the RX 6750 XT, ensuring that the GPU is the primary determinant of frame rate in most scenarios.

Settings Recommendations

The measured FPS data provides a clear picture of how the quality settings impact performance. At 1920x1080, all settings deliver playable frame rates, with the Low preset achieving 238.9 FPS, Medium at 209.2 FPS, High at 179.7 FPS, and Ultra at 145.7 FPS. The most balanced experience at this resolution is the High preset, which offers a significant visual upgrade over Medium while maintaining a frame rate well above the 144 Hz refresh rate common in gaming monitors. The Ultra preset, while visually demanding, still delivers 145.7 FPS, making it a viable option for those prioritizing image quality over raw frame rate.

Moving to 2560x1440, the High preset achieves 115.9 FPS, which is excellent for high-refresh-rate gaming. The Medium preset drops to 134.9 FPS, while Low reaches 155.5 FPS. The Ultra preset falls to 92.8 FPS, which is still smooth but shows the GPU beginning to feel the strain of higher resolution. For the best overall experience at 1440p, the High preset is the recommended choice, as it provides a substantial visual improvement over Medium while keeping the frame rate above the 100 FPS threshold. At 3840x2160, the High preset manages 64.6 FPS, which is playable, but the Ultra preset drops to 52.3 FPS. For 4K gaming, the Medium preset at 75.4 FPS offers the best compromise between visual fidelity and smoothness, as the Low preset at 84.2 FPS sacrifices too much visual quality for a marginal performance gain.

Resolution Scaling

The performance drop from 1080p to 4K is significant and reveals the GPU as the limiting component. At High settings, the frame rate drops from 179.7 FPS at 1920x1080 to 115.9 FPS at 2560x1440, a reduction of approximately 35%. This decline continues to 64.6 FPS at 3840x2160, representing a further 44% drop from 1440p. This scaling pattern is characteristic of a GPU-bound scenario, where the increased pixel count at higher resolutions puts more strain on the Radeon RX 6750 XT's shading units and memory bandwidth.

The CPU's role in this scaling is minimal, as the processor's performance is sufficient to maintain high frame rates at lower resolutions. The fact that the frame rate drops by over 50% from 1080p to 4K at High settings indicates that the GPU is the primary bottleneck, with its 2560 shading units and 12 GB of GDDR6 memory struggling to keep up with the demands of 4K rendering. The data suggests that the system is well-balanced for 1080p and 1440p gaming, but 4K gaming will require compromises in settings to maintain smooth performance.

How This Combo Ranks

The Intel Core i5-11400F and AMD Radeon RX 6750 XT combination ranks 828th out of 1681 tested combos in Doom, placing it in the upper half of the database. This ranking confirms the balance between the CPU and GPU, which work together to deliver a strong gaming experience. The GPU's performance percentile of 79, with an average benchmark score of 35327, positions it slightly below the NVIDIA GeForce RTX 3080, which has an average score of 35787 and a deltaPct of -1.3. This close competition is reflected in the gaming performance, where the RX 6750 XT proves to be a capable 1440p card.

The CPU's 75th percentile ranking, with an average score of 17181, is closely matched with its nearest rivals, all of which have deltaPct values within 0.2%. This indicates that the i5-11400F is a well-rounded processor that does not hold back the GPU in gaming scenarios. The combo's rank of 828 out of 1681 suggests that while there are many faster combinations, this pairing offers a solid balance of performance that is well-suited for high-refresh-rate 1080p and 1440p gaming, with acceptable performance at 4K.

GPU Role

The AMD Radeon RX 6750 XT is the dominant component in this pairing, built on the RDNA 2.0 architecture with a 7 nm process. It features 2560 shading units, 160 texture mapping units, and 64 raster operation pipelines. The GPU operates at a base clock of 2150 MHz, with a boost clock of 2600 MHz and a game clock of 2495 MHz. Its 12 GB of GDDR6 memory runs at an effective speed of 18 Gbps across a 192-bit bus, providing a bandwidth of 432.0 GB/s. These specifications allow the card to achieve a passmark G3D score of 20700, placing it in the 79th percentile against all GPUs.

The GPU's performance is the primary driver of the frame rates seen in Doom. Its 13.31 TFLOPS of FP32 compute power is more than sufficient for the game's engine, allowing it to push high frame rates at 1080p and 1440p. The 12 GB VRAM capacity ensures that texture-heavy scenes at higher resolutions do not cause memory-related stuttering. The GPU's nearest rival, the AMD Radeon RX 5600M, has an average score of 35264 and a deltaPct of 0.2, indicating that the RX 6750 XT is slightly faster. This performance advantage is evident in the benchmark results, where the combo achieves 179.7 FPS at 1080p High, demonstrating the GPU's ability to handle the game with ease at mainstream resolutions.
