Doom

The AMD Radeon RX 6800 XT paired with the Intel Core i5-12400F delivers a high-refresh-rate experience in Doom across all tested resolutions, with the data showing that the Ultra preset remains viable for 1440p gaming but becomes the primary bottleneck at 4K. The measured frame rates indicate a system that scales predictably with settings, making it a strong candidate for competitive play where maximizing frame rate is the priority.

Settings Recommendations

The benchmark data for Doom shows a clear hierarchy across the four tested presets at each resolution. At 1920x1080, the Low preset produces an average of 289.2 FPS, which is the highest measured frame rate in the dataset. This drops to 255.7 FPS on Medium and 213.8 FPS on High, with Ultra trailing at 175.7 FPS. For players targeting the absolute maximum refresh rate on a 1080p display, the Low preset offers the best experience, as the 289.2 FPS figure provides the most headroom above typical 144Hz or 240Hz monitor refresh rates.

At 2560x1440, the pattern shifts. Low delivers 186.9 FPS, Medium 166.6 FPS, and High 138.5 FPS, while Ultra still manages a respectable 110.8 FPS. The data suggests that High is the sweet spot for 1440p: the 138.5 FPS average comfortably exceeds 120Hz refresh rates, and the visual fidelity improvement over Medium is substantial for a first-person shooter. Ultra at 110.8 FPS remains playable, but the 27.7 FPS drop from High to Ultra is significant relative to the diminishing visual returns at this resolution.

At 3840x2160, the RX 6800 XT begins to show its limits. Low produces 103.5 FPS, Medium 88.7 FPS, and High 74 FPS, while Ultra falls to 63.9 FPS. The recommendation for 4K is Medium: the 88.7 FPS average keeps the experience smooth on standard 60Hz displays with room to spare, and the jump from Low to Medium adds meaningful detail without the steep performance cost seen at High and Ultra. High at 74 FPS is acceptable for slower-paced play, but Ultra at 63.9 FPS sits dangerously close to the 60 FPS threshold where frame-time consistency becomes a concern.

Across all resolutions, the data indicates that the Low preset is never necessary for playability—even at 4K it only buys a 14.8 FPS advantage over Medium—so the optimal choice balances visual quality with the frame rate demands of the display.

FAQ

*Q: What is the highest average frame rate this combo achieves in Doom?*

A: The maximum measured average is 289.2 FPS, achieved at 1920x1080 with the Low preset.

*Q: Can this system run Doom at 4K with the Ultra preset?*

A: Yes, but with a measured average of 63.9 FPS. This is above the 60 FPS baseline, though it leaves little margin for demanding scenes or background tasks.

Q: How much performance is lost when moving from 1080p to 1440p at the same settings?

A: At the High preset, the average frame rate drops from 213.8 FPS at 1080p to 138.5 FPS at 1440p, a reduction of 75.3 FPS. At Ultra, the drop is from 175.7 FPS to 110.8 FPS, a 64.9 FPS reduction.

Q: Which preset shows the smallest performance gap between 1440p and 4K?

A: The Low preset shows the smallest absolute gap, with 186.9 FPS at 1440p and 103.5 FPS at 4K, a difference of 83.4 FPS. In percentage terms, the High preset drops by roughly 46% between these resolutions.

Q: Is the Ultra preset ever the best choice for this combo?

A: At 1080p, Ultra still delivers 175.7 FPS, which exceeds 144Hz refresh rates, making it a viable choice for high-refresh monitors. At higher resolutions, the frame rate falls below 120 FPS, making High or Medium more appropriate.

A: The combo ranks 585th out of 1681 tested combinations, placing it in the top third of all systems in the database.

CPU Role

The Intel Core i5-12400F contributes 6 cores and 12 threads, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. This configuration is well-suited for a fast-paced FPS like Doom, where the engine's rendering thread benefits from strong single-core performance. The CPU's benchmarks reinforce this: the 3dmark single-thread score of 909 and the Cinebench R23 single-core score of 2332 indicate solid per-core throughput, which directly supports the high frame rates observed in the game.

In the measured results, the CPU's role becomes evident at lower resolutions. At 1080p with the Low preset, the system reaches 289.2 FPS, a figure that approaches the practical ceiling for many CPUs when the GPU is not fully stressed. The 3dmark 2-thread score of 1699 and 4-thread score of 3067 show that the CPU can handle the lightweight threading typical of Doom's main loop, while the 8-thread score of 4779 and max-thread score of 5912 provide ample headroom for background processes and engine tasks.

The CPU's 18 MB of shared L3 cache and 1.25 MB L2 per core help maintain low latency memory access, which is critical for maintaining consistent frame times in a shooter. At 4K, however, the GPU becomes the limiting factor, as evidenced by the frame rate scaling—the CPU's contribution is largely masked by the RX 6800 XT's rendering workload. The data shows that the i5-12400F does not bottleneck the GPU at any tested setting, as even the highest GPU-bound results at 4K (103.5 FPS on Low) are well below what the CPU's single-core capabilities would limit.

How This Combo Ranks

The combo ranks 585th out of 1681 tested combinations for Doom, placing it in the 65th percentile of all systems in the database. This position reflects a balanced pairing: the CPU ranks in the 77th percentile against all CPUs, while the GPU sits in the 87th percentile against all GPUs. The slight gap between the two percentiles suggests that the GPU is the stronger component in this pairing, which aligns with the frame rate data showing GPU-bound behavior at higher resolutions.

In the CPU's nearest rival comparisons, the i5-12400F posts an average benchmark score of 19221, which is within 0.1% of the Intel Core i7-8700K (19210) and 0.3% of the Intel Core i5-1335U (19167). It also slightly outperforms the AMD EPYC 7773X by 1.3% and trails the AMD Ryzen 5 7533HS by 0.7%. These tight margins indicate that the i5-12400F's compute performance is highly competitive with older and mobile parts, but its gaming relevance comes from the combination of solid single-thread scores and modern architecture.

For the GPU, the RX 6800 XT's average benchmark score of 49982 places it 0.5% ahead of the Intel Arc A550M and 1.9% ahead of the NVIDIA CMP 50HX, while trailing the NVIDIA RTX A1000 by 1.7% and the GeForce RTX 4070 Ti SUPER by 2.6%. The GPU's 87th percentile ranking confirms it as a high-end part, and the combo's 585th overall rank reflects that Doom is a title that rewards strong GPU performance without being overly demanding on the CPU.

Resolution Scaling

The measured frame rates reveal a predictable scaling pattern as resolution increases from 1920x1080 to 3840x2160. At the High preset, the average frame rate drops from 213.8 FPS at 1080p to 138.5 FPS at 1440p, a 35% reduction, then further to 74 FPS at 4K, a 47% reduction from 1440p. This steep decline at 4K indicates that the RX 6800 XT's rendering throughput becomes the primary constraint, as the pixel count quadruples from 1080p to 4K while the frame rate does not scale proportionally.

The Low preset shows the same trend: 289.2 FPS at 1080p drops to 186.9 FPS at 1440p and 103.5 FPS at 4K. The relative drop from 1080p to 1440p is 35%, and from 1440p to 4K is 45%, which is consistent with GPU-bound scaling. In contrast, the difference between presets at a fixed resolution is smaller: at 4K, the gap from Low to Ultra is 39.6 FPS (from 103.5 to 63.9), while at 1080p the same gap is 113.5 FPS (from 289.2 to 175.7). This widening gap at lower resolutions suggests that the CPU is capable of driving higher frame rates when the GPU is less burdened, but the GPU's limit is reached at 4K regardless of settings.

The data points to the GPU as the limiting component at 4K, given that even the Low preset cannot exceed 103.5 FPS. At 1080p, the CPU's influence is more apparent—the system's ability to reach 289.2 FPS on Low shows that the i5-12400F can sustain very high frame rates, but the GPU's architecture caps performance as resolution climbs. For players seeking maximum frame rates at 1080p, this combo excels; for 4K, the experience is smooth but capped below 100 FPS, making High and Ultra presets less practical.
