Doom

Resolution Scaling

The measured frame rates for the Intel Core i5-11400F paired with the NVIDIA GeForce RTX 5070 Ti reveal a predictable yet steep performance curve as resolution climbs. At 1080p with High settings, the combo produces 282.3 FPS. Dropping to 1440p High reduces that to 183.2 FPS, a 35% decrease. Moving to 4K High yields 101.8 FPS, which is 64% lower than the 1080p result. This steep decline indicates that the rendering load is scaling aggressively with pixel count, which is typical for a game like Doom that relies heavily on fill-rate and memory bandwidth.

The delta between settings at each resolution shows how the GPU becomes the primary limiting factor at higher pixel densities. At 1080p, the spread from Low to Ultra is 79.8 FPS (311.3 down to 231.5). At 1440p, that spread widens to 96.8 FPS (248.9 down to 152.1). At 4K, the spread is 50.9 FPS (134.8 down to 83.9). The fact that the gap between Low and Ultra narrows at 4K suggests that even the RTX 5070 Ti, with its 16 GB of GDDR7 memory and 896.0 GB/s bandwidth, is beginning to saturate under the extreme pixel workload.

The 1080p results are notably CPU-leaning. The i5-11400F's 6 cores and 12 threads, boosting to 4.40 GHz, can push frame rates well past 300 FPS at Low settings. However, the jump from 311.3 FPS at 1080p Low to 248.9 FPS at 1440p Low is a 20% drop, indicating that the GPU is already taking over the bottleneck even at the lowest quality preset. At 4K, the Low setting still manages 134.8 FPS, which is 33% higher than the 4K High result of 101.8 FPS. This shows that the RTX 5070 Ti has enough headroom to deliver playable 4K performance, but the user must carefully select settings to maintain high refresh rates.

The data supports a clear conclusion: this combo is overkill for 1080p, capable at 1440p, and demanding at 4K. The 1080p High result of 282.3 FPS is far beyond the refresh rate of most monitors, making the CPU the ceiling. At 1440p, the 183.2 FPS High result is still excellent for competitive play. At 4K, the 101.8 FPS High result is smooth, but the 83.9 FPS Ultra result indicates that the Ultra preset pushes the GPU to its limits.

Settings Recommendations

The measured rows provide a clear hierarchy for optimizing the experience. The Ultra preset delivers the highest visual fidelity but comes at a significant cost: 231.5 FPS at 1080p, 152.1 FPS at 1440p, and 83.9 FPS at 4K. These are all playable, but the 4K Ultra result is the only one that dips below the 100 FPS threshold. For users with high-refresh 4K displays, the High preset is the better choice, offering 101.8 FPS—a 21% improvement over Ultra—while presumably retaining most of the visual polish.

At 1440p, the High preset at 183.2 FPS is the sweet spot for competitive play. It is 31 FPS faster than Ultra (152.1) and only 36 FPS slower than Low (248.9). The Medium preset at 219.1 FPS offers a middle ground, but the jump from Medium to High costs only 36 FPS while likely adding substantial visual detail. At 1080p, the High preset at 282.3 FPS is the recommended choice; it is only 29 FPS slower than Low (311.3) but massively ahead of Ultra (231.5) by 50.8 FPS.

The data suggests that High is the optimal preset across all resolutions for this combination. It provides the best balance between frame rate and visual quality. The Low preset is only useful for maximizing FPS at 1080p, where the 311.3 FPS result may appeal to esports players with 360 Hz monitors. However, the 1440p Low result of 248.9 FPS is still extremely high, making Low largely unnecessary unless the user prioritizes absolute frame rate over visual fidelity.

For 4K, the choice is between High and Medium. The Medium preset at 115.8 FPS is 14 FPS faster than High (101.8), but the visual difference is likely noticeable. Given that the High preset maintains a triple-digit frame rate, it is the recommended starting point for 4K. Users who prefer maximum quality can try Ultra, but the 83.9 FPS result may feel less smooth on high-refresh panels.

GPU Role

The NVIDIA GeForce RTX 5070 Ti is the dominant component in this pairing, and the benchmark data confirms its importance. The GPU's 16 GB of GDDR7 memory on a 256-bit bus provides 896.0 GB/s of bandwidth, which is critical for Doom's fast-paced texture streaming and particle effects. The 1080p to 4K scaling shows that the GPU's 43.94 TFLOPS of FP32 compute is being fully utilized at higher resolutions, with the 4K Ultra result (83.9 FPS) being 73% slower than the 1080p Ultra result (231.5 FPS).

The GPU's clock speeds—2295 MHz base and 2452 MHz boost—are relatively modest for a high-end card, but the Blackwell 2.0 architecture's efficiency compensates. The 8960 shading units and 280 TMUs provide ample texture throughput, as evidenced by the smooth scaling from Medium to High settings. The 96 ROPs handle pixel output well, with the pixel rate of 235.4 GPixel/s ensuring that 4K resolution does not cause a catastrophic drop.

The GPU's benchmark scores place it in an interesting position. Its average benchmark score of 52086 is nearly identical to the NVIDIA GeForce RTX 4080 (52085, 0% delta), yet it is 2.5% ahead of the NVIDIA RTX A1000 (50826) and 2.5% behind the AMD Radeon Pro W6600M (53414). This suggests that the RTX 5070 Ti is a high-end performer, but the measured FPS in Doom show it is not immune to CPU bottlenecks at lower resolutions. At 1080p Low, the 311.3 FPS result is likely close to the CPU's limit, as the i5-11400F's single-thread score of 868 in 3DMark and 2029 in Cinebench R23 would indicate.

The GPU's memory bandwidth becomes the key differentiator at 4K. The jump from 1440p High (183.2 FPS) to 4K High (101.8 FPS) is a 44% drop, which is larger than the pixel count increase (2.25x). This indicates that the 16 GB frame buffer is being heavily utilized, and the 896.0 GB/s bandwidth is a limiting factor. However, the 4K Low result of 134.8 FPS shows that the GPU can still deliver high frame rates when texture quality is reduced.
