Doom

Resolution Scaling

The measured frame rates for this Intel Core i5-14600K and NVIDIA GeForce RTX 4070 Ti combination in Doom show a clear progression as resolution increases, but the shape of that curve reveals where the bottleneck shifts. At 1080p with Low settings, the combo delivers 368.1 fps, which is extraordinarily high. Moving to 1440p Low drops that to 239.8 fps, a reduction of roughly 35%. Stepping up to 4K Low yields 126.5 fps, which is another 47% reduction from the 1440p figure. The scaling is steep because at lower resolutions the CPU has more headroom to feed frames, while the GPU becomes the limiting factor as pixel count rises.

Looking at the High preset specifically, the pattern is similar but compressed. At 1080p High, the system produces 269.2 fps. At 1440p High, it falls to 173.8 fps, which is a 35% decrease. At 4K High, the average drops to 97.8 fps, another 44% lower. The fact that the percentage drops are so consistent across presets suggests that the GPU is the primary constraint at higher resolutions, while the CPU is strong enough to keep up even at 1080p where frame rates exceed 360 fps. The i5-14600K's 14 cores and 20 threads, combined with its 5.30 GHz boost clock, are evidently sufficient to avoid becoming a bottleneck in this game, which is known for being well-optimized.

The delta between Low and Ultra at each resolution also tells a story about GPU headroom. At 1080p, the gap from Low (368.1 fps) to Ultra (222.6 fps) is 145.5 fps, meaning the Ultra preset costs about 40% of the Low performance. At 4K, the same comparison shows Low at 126.5 fps versus Ultra at 79.9 fps, a 46.6 fps difference — again roughly 37% slower. This consistency indicates that the GPU's shading and memory subsystems are scaling predictably with the increased workload from higher settings, rather than hitting any unexpected wall.

Settings Recommendations

For this combination, the data suggests that High settings provide the most balanced experience across all three resolutions. At 4K High, the average of 97.8 fps clears the 60 fps threshold comfortably and approaches the 100 fps mark, which is ideal for a fast-paced FPS like Doom. The step down to Medium at 4K yields 110 fps, a 12.5% improvement, while Ultra drops to 79.9 fps — still playable but with diminishing visual returns relative to the performance cost.

At 1440p, the choice becomes more interesting. High delivers 173.8 fps, which is well above the refresh rate of most high-end monitors. Medium offers 209.4 fps, and Low reaches 239.8 fps. For competitive play where maximum frame rates matter, Low at 1440p is the clear pick. However, for a single-player campaign where visual fidelity enhances the experience, Ultra at 1440p still produces 144 fps, which is exactly the refresh rate of many popular gaming monitors. This makes Ultra at 1440p a viable option for users with 144 Hz displays.

At 1080p, every preset is playable, but the differences become academic for most users. Ultra at 222.6 fps, High at 269.2 fps, and Low at 368.1 fps all exceed what typical 1080p monitors can display. The data indicates that High at 1080p is the sensible default, as it offers a 21% improvement over Ultra in frame rate while the visual difference between High and Ultra is often subtle in fast-moving scenes. Medium at 320.6 fps is only relevant for esports settings with 360 Hz panels.

How This Combo Ranks

Within the benchmark database, this CPU-GPU pairing holds the 204th position out of 1,681 tested combinations for Doom. That places it in the top 12% of all combos tested for this game, which is a strong showing given the game's age and the number of high-end systems that have been benchmarked. The CPU itself ranks in the 93rd percentile among all processors in aggregate benchmarks, with an average score of 49,166. Its nearest rival, the AMD Ryzen 9 5950X, scores 49,062 — a delta of just 0.2%, meaning the i5-14600K is statistically tied with that 16-core part in general compute. The Intel Core i5-14600KF is 0.4% ahead, while the AMD EPYC 4345P is 0.9% ahead, and the Intel Xeon Gold 5318H trails by 1%.

The GPU's aggregate percentile is 85, with an average benchmark score of 44,900. Its nearest rival, the NVIDIA GeForce RTX 5090 Mobile, scores 45,152, which is 0.6% higher. The Intel Arc A730M is 1.5% ahead, while the AMD Radeon Pro 580 trails by 1.6% and the AMD Radeon Pro 5500 XT is 1.6% behind. These margins are tight, indicating that the RTX 4070 Ti sits in a competitive band where small architectural differences matter more than raw specifications.

The combo's rank of 204 out of 1,681 suggests that while this system is not at the absolute top tier for Doom, it outperforms the vast majority of tested configurations. The high frame rates measured at all resolutions confirm that this pairing is well-matched for this title, with neither component dragging the other down significantly.

Measured FPS Breakdown

The complete set of measured averages for this system in Doom is as follows. At 1920x1080, the Low preset produces 368.1 fps, Medium produces 320.6 fps, High produces 269.2 fps, and Ultra produces 222.6 fps. At 2560x1440, the numbers are 239.8 fps for Low, 209.4 fps for Medium, 173.8 fps for High, and 144 fps for Ultra. At 3840x2160, the averages are 126.5 fps for Low, 110 fps for Medium, 97.8 fps for High, and 79.9 fps for Ultra.

Examining the scaling from 1080p to 1440p, every preset sees a drop of roughly 35% to 38%. The smallest relative decline is in Medium, which falls from 320.6 to 209.4 fps (a 34.7% reduction). The largest is in Low, dropping from 368.1 to 239.8 fps (34.9% reduction). From 1440p to 4K, the drops are steeper, ranging from 44.5% for Low (239.8 to 126.5) to 47.2% for High (173.8 to 97.8). Ultra falls from 144 to 79.9, a 44.5% reduction, while Medium goes from 209.4 to 110, a 47.5% reduction.

These numbers illustrate that the system maintains playable frame rates even at the most demanding configuration of 4K Ultra, where 79.9 fps still exceeds the 60 fps standard. The gap between Low and Ultra narrows slightly as resolution increases: at 1080p the spread is 145.5 fps, at 1440p it is 95.8 fps, and at 4K it is 46.6 fps. This is expected because at higher resolutions, the fixed cost of rendering more pixels dominates the incremental cost of higher settings.

GPU Role

The NVIDIA GeForce RTX 4070 Ti in this configuration is built on the AD104 chip using a 5 nm process from TSMC, with 35,800 million transistors packed into a 294 mm² die. Its base clock runs at 2310 MHz with a boost of 2610 MHz, and the memory operates at 1313 MHz with 21 Gbps effective speed. The 12 GB of GDDR6X memory over a 192-bit bus provides 504.2 GB/s of bandwidth, which is a crucial factor for a game that loads textures aggressively at 4K.

The GPU's shading resources include 7,680 shading units, 240 texture mapping units, and 80 raster operation processors. It also carries 60 ray tracing cores and 240 tensor cores, though Doom's 2016 release predates widespread ray tracing adoption, so those features have limited impact here. The pixel rate of 208.8 GPixel/s and texture rate of 626.4 GTexel/s are more relevant to this game's fill-rate demands. The FP32 throughput of 40.09 TFLOPS is substantial for a GPU in this class.

The measured frame rates suggest that the RTX 4070 Ti is well-utilized in Doom. At 4K Ultra, the 79.9 fps average indicates the GPU is working near its capacity, while at 1080p Low, the 368.1 fps figure shows the GPU can push far beyond typical display refresh rates. The memory bandwidth of 504.2 GB/s appears sufficient for this title, as there is no evidence of a sudden performance cliff when moving from 1440p to 4K that would indicate a VRAM capacity or bandwidth shortfall. The 12 GB capacity is ample for Doom's requirements at any resolution in this test.
