Doom

The Intel Core i5-13400F pairs a 10-core, 16-thread Raptor Lake design with a 2.50 GHz base clock and a 4.60 GHz boost clock. Its benchmark profile shows a balanced split between lightly-threaded and heavily-threaded work: a 3DMark single-thread score of 960 and a Cinebench R23 multi-core score of 21279. In the context of Doom, which is a fast-paced FPS from 2016, this CPU’s strength lies in its high boost clock and efficient core layout. The data suggests the processor is rarely the limiting factor here; its 82nd percentile ranking among all CPUs and an average benchmark score of 25236 put it in a strong position to feed frames to a high-end GPU. The L3 cache of 20 MB shared, along with 1.25 MB of L2 per core, provides ample on-die storage for game assets, reducing the need to pull from system memory.

However, the CPU’s role becomes more apparent when looking at frame pacing at lower resolutions. At 1080p with Low settings, the combo reaches 370.5 FPS, a figure that approaches the practical limits of even high-refresh displays. The 3DMark 16-thread score of 7314, which is nearly identical to the max-thread score of 7307, indicates that the processor’s performance does not scale significantly beyond its initial core count for this workload. This means that while the 13400F is more than capable of handling Doom’s engine, its performance ceiling is defined by single-core speed and memory latency rather than raw core count. The nearest rival, the Intel Core i7-13620H, scores nearly identically (25201, deltaPct 0.1), reinforcing that this CPU sits in a performance tier where Doom’s demands are comfortably met.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4070 Ti is the dominant component in this pairing. Its 12 GB of GDDR6X memory on a 192-bit bus delivers 504.2 GB/s of bandwidth, which is far more than Doom’s 2016-era engine can fully utilize at most settings. The GPU’s boost clock of 2610 MHz and its Ada Lovelace architecture, built on a 5 nm TSMC process, provide the raw shading power needed to push extreme frame rates. The FP32 throughput of 40.09 TFLOPS is the key metric here; it translates directly into pixel and texture fill rates of 208.8 GPixel/s and 626.4 GTexel/s, respectively.

The data shows that the GPU’s performance scales predictably with resolution. At 4K Ultra, the average FPS drops to 77.7, which is a substantial decrease from the 1080p Ultra figure of 225.1. This is a clear sign that the GPU is the primary bottleneck at higher resolutions and quality presets. The VRAM capacity of 12 GB is not a limiting factor in this game, as even at 4K Ultra, the engine does not appear to exceed this allocation. The GPU’s percentile ranking of 85 and average benchmark score of 44900 place it in the upper echelon of graphics cards. Its nearest rival, the NVIDIA GeForce RTX 5090 Mobile, scores marginally higher at 45152 (deltaPct -0.6), indicating that the 4070 Ti delivers desktop-class performance that is only slightly behind the mobile flagship.

How This Combo Ranks — use comboRankInGame vs other tested combos

Within the benchmark database, this specific combination of the Intel Core i5-13400F and NVIDIA GeForce RTX 4070 Ti achieves a rank of 196 out of 1681 tested combos for Doom. This places it in the top 12% of all systems tested, which is a strong result given the age of the game. The ranking reflects that while the CPU is not the absolute fastest available, the GPU’s high-end capabilities drive the system to outperform the vast majority of configurations. The 0.1% deltaPct to the Intel Core i7-13620H in CPU benchmarks suggests that swapping the processor for a similar-tier mobile chip would not materially change the ranking.

What is more interesting is how the combo’s rank compares to its individual component percentiles. The CPU sits at the 82nd percentile, and the GPU at the 85th, yet the combo ranks in the 88th percentile of combos. This implies that the pairing is synergistic; the 13400F’s high boost clock is sufficient to keep the RTX 4070 Ti fully fed, avoiding a situation where CPU limitations drag down the GPU’s potential. The data indicates that for Doom specifically, the balance between these two components is well-suited, allowing the GPU to operate near its theoretical maximum. This is not always the case with mid-range CPUs paired with high-end GPUs, but the benchmark results show no such issue here.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the combo delivers exceptional performance across all presets. Low settings yield an average of 370.5 FPS, Medium drops to 320.8 FPS, High sits at 269 FPS, and Ultra remains high at 225.1 FPS. The scaling from Low to Ultra is a 39% reduction in frame rate, which is modest and highlights the GPU’s headroom at this resolution. Moving to 2560x1440, the frame rates remain very playable: Low produces 240.2 FPS, Medium 211.2 FPS, High 172.5 FPS, and Ultra 144.3 FPS. The drop from 1080p to 1440p at Ultra settings is 36%, consistent with the increase in pixel count.

At 3840x2160, the impact of resolution becomes evident. Low settings still manage 127.9 FPS, which is smooth for most displays, but Medium drops to 110.8 FPS, High to 95.7 FPS, and Ultra falls to 77.7 FPS. The Ultra preset at 4K is the only configuration in the dataset that dips below the 80 FPS threshold, suggesting that this is the point where the GPU’s raw throughput is no longer sufficient for maximum refresh rates. The difference between 1080p Low and 4K Ultra is a 79% reduction in average FPS, clearly illustrating the GPU’s workload scaling with resolution and settings.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

Analyzing the FPS drop from 1080p to 4K across all settings reveals the bottleneck behavior. For the Low preset, the frame rate falls from 370.5 FPS at 1080p to 127.9 FPS at 4K, a 65% decrease. For the Ultra preset, the drop is from 225.1 FPS to 77.7 FPS, a 65% decrease as well. This consistent percentage drop across all presets is a strong indicator that the GPU is the limiting component in all scenarios. If the CPU were the bottleneck, we would expect the percentage drop to be smaller at higher resolutions, as the GPU becomes more loaded and the CPU has more time to prepare frames. Instead, the uniform scaling suggests that the RTX 4070 Ti’s fill rate and memory bandwidth are the primary constraints at 4K.

The data also shows that the CPU’s influence is minimal even at 1080p Low, where the frame rate is highest. The fact that the 370.5 FPS figure is not higher suggests that the CPU’s 2.50 GHz base clock and 4.60 GHz boost clock are enough to maintain this level, but not push beyond it. The 3DMark single-thread score of 960, while respectable, indicates a limit to how fast the game’s main thread can issue draw calls. Therefore, the resolution scaling analysis points to a system where the GPU is the dominant factor, and the CPU provides sufficient support without becoming a significant drag.

Settings Recommendations

For players prioritizing maximum frame rates on high-refresh displays, the Low preset at 1920x1080 delivers 370.5 FPS, which is far beyond any monitor’s capability. The Medium preset at 320.8 FPS is a better balance for most users, offering improved visuals without sacrificing smoothness. At 2560x1440, the High preset at 172.5 FPS is the sweet spot, providing a substantial visual upgrade over Medium while still exceeding the refresh rate of most 144Hz monitors. The Ultra preset at 144.3 FPS is viable for 144Hz users, but the 16% drop from High to Ultra may not be worth the marginal visual improvement.

For 4K gaming, the High preset at 95.7 FPS is the recommended choice, as it offers a smooth experience on 60Hz displays and is a 23% improvement over Ultra’s 77.7 FPS. The Low preset at 127.9 FPS is preferable for those with 120Hz or 144Hz 4K displays, but it sacrifices significant visual fidelity. The Medium preset at 110.8 FPS is a middle ground that maintains playability. The data suggests that the Ultra preset at any resolution is the least efficient choice, as the performance cost is not proportional to the visual gain in this older game engine. Therefore, the High preset is the optimal balance of image quality and performance across all resolutions tested.
