Doom

The Intel Core i5-13400F paired with the NVIDIA GeForce RTX 5070 Ti delivers a performance profile in Doom that is heavily dictated by resolution, with the CPU proving more capable than the GPU at lower settings. The data shows a clear progression: at 1080p Low, the combo hits 382.1 FPS, while at 4K Ultra it drops to 81.1 FPS. This spread of 301 FPS between the extremes indicates that while the hardware is potent, the game’s demands scale significantly with both resolution and graphical fidelity.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial but not linear across all settings. At Low settings, the transition from 1920x1080 to 3840x2160 sees the average FPS fall from 382.1 to 133.6, a reduction of 248.5 FPS. This 65% decrease highlights that even at Low settings, 4K resolution places a heavy burden on the GPU. At High settings, the drop is from 283.3 FPS at 1080p to 98.5 FPS at 4K, a 184.8 FPS decline. The Ultra preset shows the most dramatic scaling, falling from 230.5 FPS at 1080p to 81.1 FPS at 4K.

The pattern suggests that at 1080p, the RTX 5070 Ti is not the primary limiting factor. The jump from 382.1 FPS at Low to 230.5 FPS at Ultra at 1080p shows a 151.6 FPS difference, which is less than the resolution-based drops. This indicates that the CPU, with its 10 cores and 16 threads, is able to feed frames quickly enough at this resolution, but the GPU’s workload is still the dominant variable. At 4K, the GPU is clearly the bottleneck, as the FPS figures compress between settings: 133.6 FPS at Low versus 81.1 FPS at Ultra, a gap of only 52.5 FPS. This narrowing gap shows that at 4K, the pixel-pushing demands of the RTX 5070 Ti limit performance regardless of the graphical preset.

CPU Role

The i5-13400F has a base clock of 2.50 GHz and a boost clock of 4.60 GHz, with a 20 MB shared L3 cache. Its benchmark scores place it in the 82nd percentile among all CPUs, with an average benchmark score of 25236. This positions it close to the Intel Core i7-13620H, which is only 0.1% ahead, and the AMD Ryzen 5 5600X3D, which is 0.5% ahead. The data indicates that in Doom, this CPU is sufficient to avoid being the main constraint at 1080p and 1440p, as evidenced by the high FPS figures at those resolutions.

At 2560x1440 with Low settings, the combo reaches 250.7 FPS. This is close to the 230.5 FPS achieved at 1080p Ultra, suggesting that the CPU can handle the frame generation demands of the game’s fast-paced action. The single-threaded performance, measured at 960 in 3dmark_single_thread and 3004 in cinebench_r23_singlecore, is adequate for Doom’s engine, which relies on strong per-core performance for game logic and draw calls. However, the CPU’s role becomes more apparent when comparing 1080p Low (382.1 FPS) to 1440p Low (250.7 FPS). The 131.4 FPS drop is more than what pure resolution scaling would suggest, implying that the CPU’s frame pacing capabilities are being tested as the GPU outputs more frames.

GPU Role

The RTX 5070 Ti features 16 GB of GDDR7 memory on a 256-bit bus, providing a bandwidth of 896.0 GB/s. Its boost clock is 2452 MHz, and it has 8960 shading units. The GPU benchmarks show it in the 87th percentile among all GPUs, with an average benchmark score of 52086. This places it virtually tied with the NVIDIA GeForce RTX 4080, which has a deltaPct of 0, and 0.8% ahead of the AMD Radeon RX 7700S.

In Doom, the GPU’s memory capacity and bandwidth are key. At 4K Ultra, the combo manages 81.1 FPS, which is playable but not high-refresh territory. The 16 GB VRAM is not a limiting factor in this game, as even at 4K Ultra, the FPS is dictated by compute throughput rather than memory capacity. The GPU’s FP32 performance of 43.94 TFLOPS allows for strong rasterization, which is evident in the 180.7 FPS at 1440p High. The texture rate of 686.6 GTexel/s and pixel rate of 235.4 GPixel/s support the high frame rates seen at lower resolutions. The data suggests that the GPU is the clear limiting factor at 4K, where its raw processing power is maxed out, but it excels at 1440p and below, delivering frame rates well above 144 Hz for most settings.

How This Combo Ranks

The combination of the i5-13400F and RTX 5070 Ti ranks 150th out of 1681 tested combos in Doom, placing it in the top 9% of all configurations. This is a strong showing, indicating that this pairing is well-balanced for this particular title. The high rank is supported by the measured FPS data, which shows that the combo can exceed 200 FPS at 1440p Medium (215.7 FPS) and 1080p Ultra (230.5 FPS). The rank reflects that while there are faster CPUs and GPUs individually, the synergy between this CPU and GPU avoids severe bottlenecks in Doom’s engine. The CPU’s 82nd percentile ranking and the GPU’s 87th percentile ranking both contribute to a combo that is greater than the sum of its parts, as the rank suggests a configuration that is in the upper echelon of tested systems.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce 382.1 FPS, Medium hits 333.8 FPS, High reaches 283.3 FPS, and Ultra drops to 230.5 FPS. These figures show that at 1080p, the hardware is capable of driving high-refresh-rate monitors, with even the most demanding preset exceeding 230 FPS.

Moving to 2560x1440, the performance remains strong but shows a clear step down. Low settings achieve 250.7 FPS, Medium hits 215.7 FPS, High reaches 180.7 FPS, and Ultra produces 150 FPS. This resolution is the sweet spot for the RTX 5070 Ti, as it maintains over 150 FPS on the Ultra preset.

At 3840x2160, the GPU workload becomes the dominant factor. Low settings yield 133.6 FPS, Medium produces 114.8 FPS, High reaches 98.5 FPS, and Ultra drops to 81.1 FPS. The data shows that 4K gaming is viable but requires lowering settings to approach 144 Hz, with only the Low preset breaking the 120 FPS mark. The scaling from 1080p Low to 4K Low (382.1 to 133.6 FPS) demonstrates that the GPU’s compute resources are stretched by the increased pixel count, while the CPU maintains its frame-feeding role without becoming a bottleneck.
