# Doom — Intel Core i5-13400F + AMD Radeon RX 6750 XT

This combination of Intel's Core i5-13400F and AMD's Radeon RX 6750 XT delivers strong performance in Doom, with measured frame rates that scale predictably across resolutions and settings. The pairing sits in the 816th position out of 1,681 tested combos for this title, placing it comfortably in the upper half of the database. The data shows a system that handles the 2016 FPS with authority at 1080p, remains highly playable at 1440p, and only begins to show strain at 4K with maximum quality settings.

Resolution Scaling

The measured FPS data for this combo reveals a clear pattern of scaling from 1080p to 4K that points to the GPU as the primary limiting factor at higher resolutions. At High settings, average frame rates drop from 180 FPS at 1920x1080 to 114.2 FPS at 2560x1440, a reduction of roughly 37% when moving to 1440p. The jump to 3840x2160 brings the average down to 62.1 FPS, which represents a further 46% decline from the 1440p result. This progressive degradation is typical of a system where the graphics card becomes increasingly saturated as pixel count rises.

The scaling behavior at Low settings tells a similar story, though with higher absolute numbers. The combo produces 241.2 FPS at 1080p Low, which falls to 155.5 FPS at 1440p and 85.4 FPS at 4K. The percentage drops between resolutions are consistent with the High settings results, reinforcing that resolution is the dominant variable. Interestingly, the gap between Low and High settings narrows as resolution increases: at 1080p the difference is 61.2 FPS, at 1440p it's 41.3 FPS, and at 4K it shrinks to 23.3 FPS. This convergence suggests that at 4K, the GPU's rendering throughput becomes the bottleneck regardless of the quality preset, while at lower resolutions the settings have more headroom to influence performance.

Ultra settings show the steepest curve, with 146.1 FPS at 1080p dropping to 93.2 FPS at 1440p and 53 FPS at 4K. The 4K Ultra result is the only measured configuration that falls below the 60 FPS threshold, indicating that this combo requires a slight settings reduction for smooth 4K gameplay. The overall pattern across all four settings presets demonstrates a system that is well-balanced for 1080p and 1440p gaming but approaches its practical limit at 4K with high or ultra quality.

GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with the Navi 22 chip, manufactured on a 7 nm process at TSMC. The GPU operates with a base clock of 2150 MHz and a boost clock of 2600 MHz, with a game clock rated at 2495 MHz. Memory runs at 2250 MHz with 18 Gbps effective transfer, delivering 432.0 GB/s of bandwidth across a 192-bit bus. The card carries 12 GB of GDDR6 memory, which provides ample capacity for Doom's texture and geometry data at all tested resolutions.

The GPU's shading resources include 2,560 shading units, 160 texture mapping units, and 64 raster operations pipelines. It also features 40 ray tracing cores, though Doom's 2016 engine does not leverage ray tracing, so these cores remain idle during gameplay. The compute throughput is rated at 13.31 TFLOPS for FP32 operations, with pixel rate of 166.4 GPixel/s and texture rate of 416.0 GTexel/s. These specifications place the RX 6750 XT in the 79th percentile among all GPUs in the database, with an average benchmark score of 35,327.

In the context of Doom's measured results, the GPU's memory bandwidth of 432.0 GB/s appears sufficient for the game's demands. The 4K Ultra result of 53 FPS suggests that the card's raw compute capacity, rather than memory bandwidth, is the limiting factor at that resolution. The benchmark scores for this GPU show it ranking closely alongside the AMD Radeon RX 5600M (0.2% ahead), the NVIDIA GeForce RTX 5070 Ti Mobile (0.3% behind), and the AMD Radeon 880M (0.9% behind). These rival comparisons indicate that the RX 6750 XT sits in a competitive mid-range tier, though the desktop-oriented nature of this card gives it an edge in sustained workloads like gaming.

CPU Role

The Intel Core i5-13400F provides the processing foundation for this combo, featuring 10 cores and 16 threads based on the Raptor Lake architecture. The CPU runs at a base clock of 2.50 GHz and boosts up to 4.60 GHz, with a 65 W TDP that keeps thermal demands modest. It supports dual-channel DDR4 or DDR5 memory and connects via PCIe Gen 5 with 16 lanes from the CPU. The cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache.

For Doom, a game originally released in 2016, the CPU's single-thread performance is particularly relevant. The processor scores 3,004 in Cinebench R23 single-core and 21,279 in the multi-core test, indicating strong per-thread capability. The 3DMark results show a single-thread score of 960 and a 16-thread score of 7,314, with the max-thread score of 7,307 nearly identical, suggesting that the CPU's performance scales well up to its full thread count. This behavior aligns with Doom's engine, which typically utilizes multiple threads but still benefits from strong single-core throughput.

The CPU's 82nd percentile ranking among all CPUs, with an average benchmark score of 25,236, places it in a solid mid-to-high tier. Its nearest rivals include the Intel Core i7-13620H (0.1% ahead), the AMD Ryzen 5 5600X3D (0.5% behind), the AMD EPYC 9474F (0.5% ahead), and the AMD Ryzen AI 5 PRO 340 (0.5% ahead). These tightly clustered scores indicate that the i5-13400F delivers performance comparable to several other processors in its class. In the context of Doom's frame rates, the CPU does not appear to bottleneck the GPU at any tested resolution, as evidenced by the consistent scaling pattern from 1080p to 4K.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings produce an average of 241.2 FPS, Medium achieves 209.8 FPS, High reaches 180 FPS, and Ultra still manages 146.1 FPS. All four presets exceed the refresh rate of typical 144 Hz monitors, meaning gamers can enable maximum quality without sacrificing smoothness at this resolution. The spread of 95.1 FPS between Low and Ultra demonstrates the GPU's headroom at 1080p.

Moving to 2560x1440, the averages remain strong but show the expected decline. Low settings yield 155.5 FPS, Medium delivers 136.7 FPS, High produces 114.2 FPS, and Ultra drops to 93.2 FPS. The Ultra result at 1440p still exceeds 90 FPS, providing a comfortable experience for high-refresh-rate 1440p displays. The gap between Low and Ultra narrows to 62.3 FPS, reflecting the increased GPU workload at this resolution.

At 3840x2160, the combo's limits become apparent. Low settings average 85.4 FPS, Medium achieves 74.7 FPS, High reaches 62.1 FPS, and Ultra falls to 53 FPS. The 4K Ultra result is the only configuration that dips below the 60 FPS threshold, making it the sole scenario where users might consider lowering settings for smoother gameplay. The progression from 1080p to 4K shows a consistent halving of frame rates at each resolution step, with the 4K results indicating that the GPU is operating near its maximum capacity for this title.

How This Combo Ranks

Within the database of tested combinations for Doom, this pairing of the Intel Core i5-13400F and AMD Radeon RX 6750 XT achieves the 816th position out of 1,681 combos. This ranking places it in the 48.5th percentile of all tested systems, meaning roughly half of the configurations in the database outperform it while the other half fall behind. Given that the CPU ranks in the 82nd percentile and the GPU in the 79th percentile individually, the combined ranking is slightly lower than either component's standalone percentile, suggesting that Doom's performance is influenced by factors beyond raw component scores.

The measured data indicates that this combo is well-suited for high-refresh-rate gaming at 1080p and 1440p, with all settings presets at those resolutions delivering frame rates above 90 FPS. At 4K, the system remains playable at Low through High settings, with only Ultra quality dropping below 60 FPS. The rank of 816 out of 1,681 reflects a system that delivers solid, reliable performance for this title without reaching the top tier of configurations. For gamers targeting 1440p with maximum settings, this combo provides a comfortable margin, while 4K enthusiasts will need to make modest quality adjustments to maintain smooth frame rates.
