Doom

The Intel Core i7-12700K paired with the AMD Radeon RX 6750 XT delivers a remarkably consistent experience in Doom, with the data showing a clear narrative about where performance bottlenecks lie. Across the measured resolutions, the combo demonstrates that this 2016 FPS title remains highly scalable on modern hardware, but the scaling pattern reveals a distinct shift in the limiting component as resolution increases. The benchmark results indicate a system that is exceptionally strong at 1080p, still highly capable at 1440p, and only begins to show strain at 4K Ultra settings.

Resolution Scaling

The measured FPS data shows a predictable decline as resolution increases, but the rate of that decline is telling. At 1080p with High settings, the combo produces 176.6 FPS, which drops to 113.4 FPS at 1440p — a reduction of roughly 36%. Moving to 4K High yields 59.8 FPS, which is a further 47% drop from the 1440p figure. This steepening curve suggests that the GPU is becoming the primary limiting factor at higher resolutions, while the CPU has ample headroom to feed frames at lower pixel counts.

The Low settings preset illustrates this dynamic even more clearly. At 1080p Low, the system achieves 244 FPS, which is a massive figure that indicates the CPU is capable of pushing well beyond typical display refresh rates. At 1440p Low, the frame rate drops to 157.9 FPS, and at 4K Low it falls to 85.4 FPS. The gap between 1080p and 1440p Low is 86.1 FPS, while the gap between 1440p and 4K Low is 72.5 FPS. This relatively even distribution across all three resolutions at Low settings suggests a balanced workload, but the fact that 4K Low still delivers 85.4 FPS indicates the GPU has substantial raw throughput even when pixel count quadruples.

Examining the Ultra preset reveals the most dramatic scaling penalty. The 1080p Ultra score of 145.1 FPS falls to 94.9 FPS at 1440p, then plummets to 50 FPS at 4K. The 4K Ultra result is exactly half the 1080p Ultra figure, which strongly implies the GPU is hitting a hard computational ceiling at that resolution and settings combination. The data shows that the drop from 1440p to 4K at Ultra (44.9 FPS) is nearly as large as the drop from 1080p to 1440p at the same preset (50.2 FPS), indicating that the pixel-count scaling is not linear — the higher resolution demands disproportionately more GPU resources.

GPU Role

The AMD Radeon RX 6750 XT sits at the center of this performance story, and its specifications align well with the measured results. The GPU features 12 GB of GDDR6 memory on a 192-bit bus, providing 432.0 GB/s of bandwidth. This memory configuration appears sufficient for Doom’s demands, as the 4K High result of 59.8 FPS suggests the card is not running out of memory capacity at any tested setting.

Clock speeds play a significant role in the observed scaling behavior. The GPU has a base clock of 2150 MHz and a boost clock of 2600 MHz, with a game clock of 2495 MHz. The 450 MHz difference between base and boost clocks indicates the card can dynamically adjust its frequency based on thermal and power headroom, which likely explains why the 4K results remain playable even at Ultra settings. The 50 FPS 4K Ultra figure, while low, is still above the 30 FPS threshold that would indicate a slideshow-like experience.

The GPU’s architecture, RDNA 2.0, is built on a 7 nm process at TSMC, with 17,200 million transistors on a 335 mm² die. The 2560 shading units, 160 TMUs, and 64 ROPs provide the raw compute necessary to handle Doom’s geometry and texture work. The FP32 throughput of 13.31 TFLOPS is respectable for this class of card, and the data suggests it is well-matched to the i7-12700K for this game — neither component appears to be drastically over- or under-powered relative to the other.

Settings Recommendations

The measured rows provide clear guidance on which preset offers the best experience. For players targeting 60 FPS as a baseline, 4K Ultra is the only preset that fails to meet that threshold, with its 50 FPS average. The 4K High preset at 59.8 FPS is borderline, technically below 60 FPS but close enough that most users would find it acceptable, especially since the minimum FPS data is not provided.

At 1440p, the data shows that Ultra settings at 94.9 FPS provide a smooth experience that exceeds 90 FPS, making it the recommended choice for high-refresh-rate monitors in this resolution. The 1440p High preset at 113.4 FPS offers additional headroom for competitive play, but the visual fidelity difference between High and Ultra is likely minimal in Doom’s fast-paced combat scenarios.

For 1080p, the Ultra preset at 145.1 FPS is the clear winner — it provides nearly 150 FPS, which is well above the 144 Hz refresh rate common on gaming monitors. The Medium preset at 209 FPS and Low at 244 FPS offer diminishing returns for most users, as the human eye typically cannot perceive differences beyond 144-165 Hz. The data suggests that 1080p Ultra is the sweet spot, delivering the highest visual quality while still maintaining frame rates that exceed the refresh rate of most displays.

CPU Role

The Intel Core i7-12700K is a 12-core, 20-thread processor based on the Alder Lake architecture, built on Intel’s 10 nm process. Its base clock of 3.60 GHz and boost clock of 5.00 GHz provide substantial single-thread performance, which is crucial for Doom’s engine. The CPU’s 25 MB of shared L3 cache and 1.25 MB per-core L2 cache help keep frequently accessed data close to the cores, reducing latency in gameplay scenarios.

The benchmark data indicates this CPU has significant headroom in Doom. The 1080p Low result of 244 FPS is a strong indicator that the CPU can drive frame rates far beyond what most displays can show, and the fact that this figure drops to 157.9 FPS at 1440p and 85.4 FPS at 4K shows that the GPU is increasingly becoming the bottleneck as resolution rises. The CPU’s 3dmark scores — 1043 in single-thread, 2065 in 2-thread, and 9979 in max-thread — demonstrate balanced scaling across thread counts, which aligns well with Doom’s multi-threaded rendering workload.

The CPU’s passmark multithread score of 34404 and single-thread score of 4013 place it in the 89th percentile of all CPUs, indicating it is a top-tier performer for gaming workloads. Its cinebench r23 multicore score of 29241 is particularly impressive, suggesting that even heavily threaded games would not saturate this processor. In Doom specifically, the data implies the CPU is rarely the limiting factor — the system is GPU-bound at 4K and likely CPU-bound only at 1080p Low, where the 244 FPS figure approaches the practical limits of the game’s engine.

Measured FPS Breakdown

At 1920x1080, the full range of settings produces a wide spread of results. Low settings achieve 244 FPS, Medium reaches 209 FPS, High delivers 176.6 FPS, and Ultra drops to 145.1 FPS. The progression from Low to Ultra reduces performance by 98.9 FPS, with each preset step costing roughly 33 FPS on average.

At 2560x1440, the results are more compressed. Low settings produce 157.9 FPS, Medium delivers 133.5 FPS, High reaches 113.4 FPS, and Ultra falls to 94.9 FPS. The total spread here is 63 FPS, indicating that the GPU’s workload at this resolution reduces the impact of settings changes compared to 1080p.

At 3840x2160, the spread narrows further. Low settings achieve 85.4 FPS, Medium reaches 73.8 FPS, High delivers 59.8 FPS, and Ultra bottoms out at 50 FPS. The 35.4 FPS difference between Low and Ultra at 4K is the smallest across all resolutions, confirming that the GPU is the dominant constraint at this pixel count.

The data reveals an interesting pattern: the gap between Low and Medium is consistently smaller than the gap between Medium and High or High and Ultra. At 1080p, Low-to-Medium is 35 FPS, Medium-to-High is 32.4 FPS, and High-to-Ultra is 31.5 FPS. This near-linear degradation suggests that each settings tier imposes a similar computational cost, but the absolute frame rates become less meaningful as resolution increases.

How This Combo Ranks

The Intel Core i7-12700K and AMD Radeon RX 6750 XT combination ranks 852nd out of 1681 tested combos in Doom, placing it in the upper-middle portion of the database. This ranking reflects a balanced pairing that is neither at the current-generation nor struggling to keep up. The combo’s position in the 50th-51st percentile suggests that while the individual components are strong — the CPU in the 89th percentile and GPU in the 79th percentile — the game’s performance characteristics do not fully reward this pairing.

The CPU’s nearest rivals provide context for its performance. The AMD Ryzen 7 PRO 5845 scores 35802, which is 0.3% higher than the i7-12700K’s 35684, while the Intel Core i7-13700T is 0.6% lower. These tiny deltas indicate that the i7-12700K is effectively tied with its closest competitors, and any performance differences in Doom would be imperceptible. The CPU’s strengths in synthetic benchmarks — particularly its cinebench r23 multicore score of 29241 — do not translate into a top-tier gaming rank, suggesting that Doom does not heavily tax the processor’s capabilities.

The GPU’s nearest rivals show a similar clustering. The RX 6750 XT scores 35327, just 0.2% above the RX 5600M and 0.3% below the RTX 5070 Ti Mobile. The RTX 3080, a notably more powerful card on paper, scores only 1.3% higher in the aggregate benchmark, which explains why the combo’s in-game rank is not higher — the GPU is performing near the level of its direct competitors, but none of these cards are top-tier for Doom at 4K Ultra. The 50 FPS 4K Ultra result is the weakest point in the measured data, and it is this figure that likely drags the combo’s rank below what the CPU’s impressive synthetic scores might suggest.
