Doom

The Intel Core i5-11400F paired with the AMD Radeon RX 7600 XT delivers a broad range of frame rates in Doom, from 43 FPS at 4K Ultra to 202 FPS at 1080p Low. This combination ranks 2346th out of 3712 tested combos in the database, placing it in the lower-middle portion of the field. The measured data spans three resolutions and four settings presets, providing a complete picture of how this system scales under load.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial across every settings preset. At High settings, average FPS falls from 148 at 1920x1080 to 96 at 2560x1440, then to 52 at 3840x2160. That represents a 35% reduction from 1080p to 1440p, and a further 46% reduction from 1440p to 4K. The total scaling from 1080p to 4K at High settings is a 65% loss in average frame rate.

Low settings show a similar pattern but with higher absolute numbers. The system produces 202 FPS at 1080p Low, 130 FPS at 1440p Low, and 71 FPS at 4K Low. The percentage drops are 36% from 1080p to 1440p and 45% from 1440p to 4K. Medium settings follow the same trajectory: 176 FPS at 1080p, 114 FPS at 1440p, and 62 FPS at 4K.

Ultra settings exhibit the steepest scaling curve. At 1080p Ultra, the average is 121 FPS. This drops to 78 FPS at 1440p Ultra, a 36% reduction. At 4K Ultra, the average falls to 43 FPS, which is a 45% drop from 1440p and a 64% drop from 1080p overall. The 4K Ultra result sits below the 60 FPS threshold that many users consider the minimum for smooth gameplay.

The scaling pattern indicates that the GPU becomes the primary limiting component as resolution increases. At 1080p, the frame rates exceed 120 FPS on all presets, suggesting the CPU can feed the GPU adequately at lower pixel counts. The consistent percentage drops between 1440p and 4K across all settings — roughly 45% to 46% — point to a pixel-bound workload where the RX 7600 XT's rendering throughput determines the ceiling.

At 4K, even Low settings only reach 71 FPS average. The gap between Low and Ultra at 4K is 28 FPS (71 versus 43), which is a smaller absolute spread than at 1080p where the gap is 81 FPS (202 versus 121). This compression of frame rates at higher resolutions reinforces that the GPU is saturated regardless of settings when pixel count increases.

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor from the Rocket Lake generation, built on Intel's 14 nm process. It has a base clock of 2.60 GHz and a boost clock of 4.40 GHz. The processor carries a 12 MB shared L3 cache, with 80 KB of L1 and 512 KB of L2 per core. Its benchmark scores show a solid mid-range position: the Cinebench R23 multicore result is 14340, and the single-core result is 2024.

In the broader CPU benchmark landscape, the i5-11400F sits at the 71st percentile among all CPUs. Its average benchmark score is 17177. The nearest rivals show tight competition: the AMD EPYC 7H12 scores 17120 (0.3% higher), while the Intel Core i5-12450H scores 17239 (0.4% higher). The AMD Ryzen 3 PRO 8300G is 0.6% above at 17278, and the Intel Core Ultra 7 164U is 0.6% below at 17074.

For Doom specifically, the CPU's 6 cores and 12 threads appear sufficient to sustain high frame rates at 1080p. The measured 202 FPS at Low settings and 148 FPS at High settings indicate that the processor is not bottlenecking at these resolution and settings combinations. The 3DMark results support this: the 2-thread score is 1691, the 4-thread score is 3171, the 8-thread score is 4691, and the 16-thread score is 5619. The scaling from 2 to 8 threads is nearly linear (1691 to 4691), which suggests the processor handles multi-threaded workloads efficiently.

The boost clock of 4.40 GHz is relevant for a game like Doom that benefits from strong single-thread performance. The Cinebench R20 single-core score of 850 and Geekbench single-core score of 1777 both indicate competitive per-core throughput. At 1080p, where the GPU has more headroom, the CPU's clock speed and core count enable frame rates above 120 FPS on all presets.

However, the CPU's role diminishes as resolution increases. At 4K, the frame rates across all settings (43 to 71 FPS) are far below what the CPU could theoretically support. The processor's PassMark single-thread score of 2981 and multithread score of 16908 suggest it has ample headroom for Doom's engine at lower resolutions, but the GPU becomes the limiting factor at 1440p and especially 4K.

GPU Role

The AMD Radeon RX 7600 XT is built on the RDNA 3.0 architecture with the Navi 33 chip, manufactured on TSMC's 6 nm process. It has 2048 shading units, 128 texture mapping units, and 64 render output units. The GPU operates at a base clock of 1980 MHz, a game clock of 2470 MHz, and a boost clock of 2755 MHz. Memory is 16 GB of GDDR6 on a 128-bit bus, providing 288.0 GB/s of bandwidth.

The GPU's benchmark profile places it at the 60th percentile among all GPUs, with an average benchmark score of 17083. Its nearest rivals include the NVIDIA GeForce GTX 690 at 17037 (0.3% lower), the AMD Radeon HD 7970M at 17019 (0.4% lower), and the NVIDIA GeForce RTX 3070 at 17208 (0.7% higher). The PassMark G3D score is 17132, while the DirectX 12 score is 65 and the DirectX 11 score is 167.

In Doom, the GPU's rendering capabilities directly determine the frame rates at higher resolutions. At 4K, the average FPS ranges from 43 (Ultra) to 71 (Low), which indicates that the GPU is working near its limits. The 16 GB VRAM capacity is more than sufficient for this game, as Doom's texture requirements are well below that amount even at 4K Ultra.

The memory bandwidth of 288.0 GB/s plays a role in the scaling behavior. At 1080p, the GPU delivers 121 FPS at Ultra and 202 FPS at Low, showing that bandwidth and compute resources are adequate for lower pixel counts. The drop to 43 FPS at 4K Ultra suggests that the GPU's compute throughput, rather than VRAM capacity, is the limiting factor.

The FP32 performance of 22.57 TFLOPS and pixel rate of 176.3 GPixel/s provide context for the 4K results. The texture rate of 352.6 GTexel/s helps explain why High settings at 1440p (96 FPS) remain playable while 4K Ultra (43 FPS) falls below smooth thresholds. The boost clock of 2755 MHz is the highest frequency the GPU can reach under load, and the measured results indicate that thermal or power constraints are not artificially limiting performance in this test.

How This Combo Ranks

The combination of the Intel Core i5-11400F and AMD Radeon RX 7600 XT ranks 2346th out of 3712 tested combos in Doom, which places it in the 63rd percentile of all tested systems. This rank reflects the GPU's mid-tier positioning rather than the CPU's, since the i5-11400F sits at the 71st percentile among CPUs while the RX 7600 XT sits at the 60th percentile among GPUs.

The gap between the CPU's percentile and the combo's rank suggests that Doom's performance at the tested resolutions is more dependent on GPU capability. The combo rank is below the CPU percentile but slightly above the GPU percentile, indicating a balanced pairing where neither component drastically undermines the other. The GPU's percentile of 60 aligns closely with the combo rank percentile of approximately 63, reinforcing that the graphics card is the primary determinant of this system's standing.

Against the GPU's nearest rivals, the RX 7600 XT is within 0.7% of the RTX 3070 in average benchmark score. In Doom, this translates to frame rates that are competitive with systems using that GPU, though direct comparison data is not available in this fact pack. The CPU's nearest rivals similarly show tight grouping, with all four within 0.6% of the i5-11400F's average score.

The rank of 2346 out of 3712 means that roughly 1366 tested combos perform worse in Doom, while about 2345 perform better. This places the system in the lower-middle tier of the database, which is consistent with the measured frame rates that range from playable at 1080p to marginal at 4K Ultra.

Measured FPS Breakdown

At 1920x1080, the system produces its highest frame rates. Low settings yield an average of 202 FPS. Medium settings average 176 FPS, with a minimum of 149 FPS and a maximum of 202 FPS. High settings average 148 FPS. Ultra settings average 121 FPS. All presets at 1080p exceed the 120 FPS mark, making this resolution suitable for high-refresh-rate displays.

At 2560x1440, performance remains strong but drops noticeably. Low settings average 130 FPS. Medium settings average 114 FPS, with a minimum of 97 FPS and a maximum of 131 FPS. High settings average 96 FPS. Ultra settings average 78 FPS. The 1440p results show that Medium is the only preset with a recorded minimum below 100 FPS, at 97 FPS.

At 3840x2160, the system struggles to maintain high frame rates. Low settings average 71 FPS. Medium settings average 62 FPS, with a minimum of 52 FPS and a maximum of 71 FPS. High settings average 52 FPS. Ultra settings average 43 FPS. Only Low settings at 4K exceed the 60 FPS average threshold, and even that result has no recorded minimum value to indicate consistency.

The Medium settings rows include min and max FPS data, which provides insight into frame time consistency. At 1080p Medium, the range from 149 to 202 FPS shows a 53 FPS spread. At 1440p Medium, the range narrows to 97 to 131 FPS, a 34 FPS spread. At 4K Medium, the range is 52 to 71 FPS, a 19 FPS spread. The narrowing range as resolution increases suggests that the GPU's workload becomes more uniform at higher pixel counts, reducing variability.

Settings Recommendations

For 1920x1080 displays, Ultra settings at 121 FPS average provide the best visual quality while maintaining frame rates well above 60 FPS. The gap between High (148 FPS) and Ultra (121 FPS) is 27 FPS, but the Ultra preset delivers the maximum visual fidelity with only a moderate frame rate cost. Even the lowest recorded performance at 1080p, which is the 149 FPS minimum at Medium, remains smooth.

At 2560x1440, High settings at 96 FPS average offer the best balance. Ultra drops to 78 FPS, which is still playable but represents a 19% reduction from High. Medium at 114 FPS provides more headroom, but the visual quality reduction from High to Medium may not be worth the 18 FPS gain for most users. The 96 FPS average at High is above the 60 FPS threshold and approaches the 100 FPS mark that many consider ideal for competitive play.

At 3840x2160, Low settings at 71 FPS average are the only preset that maintains a comfortable margin above 60 FPS. Medium at 62 FPS is playable but close to the threshold, with a recorded minimum of 52 FPS that could result in noticeable stutters. High at 52 FPS and Ultra at 43 FPS fall below the smooth gameplay standard. For 4K users, Low settings are recommended, with Medium as a compromise if the minimum frame rate of 52 FPS is acceptable.

Across all resolutions, the data shows that the system's best experience is at 1080p Ultra or 1440p High. The 1080p Ultra result of 121 FPS combines high visual quality with frame rates suitable for 120 Hz displays. The 1440p High result of 96 FPS offers a good balance for users with 1440p monitors who prioritize smoothness over maximum settings. At 4K, the system is best suited for Low or Medium settings, as the higher presets drop below acceptable frame rates.
