Doom

The Doom benchmark results for the Intel Core i5-14600KF paired with the AMD Radeon RX 7900 XTX place this combination at rank 500 out of 3712 tested configurations, putting it in the top 13.5% of all recorded combos. The data shows a system capable of extreme frame rates, but the relationship between its components reveals distinct bottlenecks depending on resolution and settings.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-14600KF is a 14-core, 20-thread processor built on the Raptor Lake architecture, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. Its 24 MB of shared L3 cache and dual-channel memory support for DDR4 and DDR5 position it as a high-end desktop part, and its benchmark scores confirm this: it achieves 32544 points in Cinebench R23 multi-core and 4594 in single-core. The processor's 90th percentile ranking against all CPUs indicates it sits comfortably near the top of the performance spectrum.

In Doom, which is a fast-paced FPS from 2016, the CPU's single-thread performance is critical. The data shows that at 1080p Low settings, the combo produces 366 FPS, while at 1080p Ultra, it drops to 220 FPS. This 146 FPS swing across settings at the same resolution suggests that while the CPU can feed the GPU at lower settings, the increased graphical load at Ultra shifts the bottleneck toward the graphics card. The i5-14600KF's 5.30 GHz boost clock and strong single-core Cinebench score of 4594 indicate it has ample headroom to drive high frame rates in this engine, which is known for being well-optimized and not heavily multi-threaded.

Comparing to its nearest rivals in the CPU benchmark database, the i5-14600KF scores 49394 on average, which is 0.3% higher than the AMD Ryzen 9 7900's 49228 and 0.8% higher than the Intel Core Ultra 5 245's 48995. It trails the AMD Ryzen AI Max+ 388 by 0.8%, which scores 49796. These marginal differences of less than one percent suggest that in Doom, any of these CPUs would perform nearly identically, making the GPU the more significant variable in frame rate outcomes. The 14 cores and 20 threads are more than sufficient for this game's demands, and the processor's 125 W TDP reflects a balance between power draw and performance that does not constrain the GPU in this title.

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

The AMD Radeon RX 7900 XTX is a flagship GPU from the Radeon RX 7000 series, built on the RDNA 3.0 architecture with the Navi 31 chip. It features 24 GB of GDDR6 memory on a 384-bit bus, delivering 960.0 GB/s of bandwidth. Its boost clock reaches 2498 MHz, with a game clock of 2365 MHz, and it houses 6144 shading units, 384 TMUs, and 192 ROPs. The GPU's 64th percentile ranking against all GPUs is notable, though its nearest rivals in the database include the NVIDIA GeForce GTX 1060 3 GB (0.4% higher score), which is surprising given the massive architectural gap—this likely reflects the benchmark database's scoring methodology rather than real-world gaming performance.

In Doom, the GPU's role is substantial at higher resolutions and settings. At 4K Ultra, the combo averages 77 FPS, while at 4K Low, it hits 128 FPS—a 51 FPS difference that shows the GPU's raw compute is the limiting factor when graphical fidelity is maximized. The 24 GB VRAM is far more than Doom requires, even at 4K Ultra, so memory capacity is not a constraint here. The 960.0 GB/s bandwidth ensures the GPU's 61.39 TFLOPS FP32 compute can be fed without starvation, which is evident in the consistent frame rates across the resolution scaling.

The GPU's 3DMark Steel Nomad DX12 score of 6841 and Passmark G3D score of 31238 indicate strong DirectX 12 performance, which aligns with Doom's Vulkan and OpenGL APIs. The RX 7900 XTX's 96 ray accelerators and DirectX 12 Ultimate support are irrelevant for this 2016 title, but its raw rasterization power drives the high frame rates seen in the data. The GPU's 355 W TDP and dual-slot design suggest it is a power-hungry part, but the benchmark results show it pairs effectively with the i5-14600KF to deliver playable-to-excellent performance across all tested configurations.

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

The measured FPS data reveals a clear pattern of resolution scaling that shifts the bottleneck between CPU and GPU. At 1080p, the combo achieves 366 FPS on Low, 319 on Medium, 269 on High, and 220 on Ultra. Moving to 1440p, those numbers drop to 237, 206, 174, and 143 respectively. At 4K, the figures fall further to 128, 112, 94, and 77. The percentage drops from 1080p to 4K are substantial: on Low settings, the frame rate falls by 65%, from 366 to 128 FPS; on Ultra, it drops by 65% as well, from 220 to 77 FPS.

This consistent ~65% reduction across settings indicates that the GPU is the primary limiter as resolution increases, because the CPU's workload remains relatively constant while the GPU must render exponentially more pixels. The 1080p Low result of 366 FPS suggests the CPU can push far beyond what the GPU can render at higher resolutions, but at 4K Ultra, the 77 FPS average shows the GPU is working near its limits. The medium settings at each resolution show the min FPS values: 271 at 1080p, 176 at 1440p, and 95 at 4K, with max FPS of 367, 237, and 129 respectively. These ranges indicate that frame pacing remains stable even when the GPU is heavily loaded, with no severe dips that would suggest driver or memory issues.

The data shows that at 1080p, the CPU is the limiting factor at low settings, as the GPU is capable of higher frame rates than the CPU can feed. At 4K, the GPU becomes the clear bottleneck, as the CPU's 5.30 GHz boost clock and 14 cores are more than capable of handling the game's logic while the GPU struggles with the pixel workload. This is textbook behavior for a well-balanced high-end system, where the bottleneck shifts logically with resolution.

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

At 1920x1080, the combo delivers its highest frame rates. Low settings produce 366 FPS average, Medium yields 319 FPS with a min of 271 and max of 367, High reaches 269 FPS, and Ultra drops to 220 FPS. These numbers indicate that even at the most demanding 1080p settings, the system is far above the 144 Hz refresh rate common on gaming monitors, making this resolution effectively a CPU-bound scenario where the GPU idles.

At 2560x1440, the performance remains strong but shows the GPU starting to take on more work. Low averages 237 FPS, Medium averages 206 FPS with a min of 176 and max of 237, High averages 174 FPS, and Ultra averages 143 FPS. The 1440p results still exceed 140 FPS even at Ultra, which is excellent for high-refresh-rate 1440p displays, and the min FPS of 176 on Medium shows consistent frame delivery without stutters.

At 3840x2160, the GPU is clearly stressed. Low averages 128 FPS, Medium averages 112 FPS with a min of 95 and max of 129, High averages 94 FPS, and Ultra averages 77 FPS. These 4K numbers are playable, but the Ultra setting at 77 FPS is the only point where the system dips below 80 FPS, indicating that 4K Ultra is the most demanding configuration tested. The drop from 4K Medium's 112 FPS to 4K Ultra's 77 FPS is a 35 FPS reduction, showing that the Ultra preset's additional graphical effects significantly tax the GPU.

How This Combo Ranks — use comboRankInGame vs other tested combos

The Intel Core i5-14600KF and AMD Radeon RX 7900 XTX combination ranks 500th out of 3712 tested combos in Doom, placing it in the 86.5th percentile of all configurations tested. This top-14% ranking is impressive, but it is not at the absolute top, which suggests that there are combinations with faster GPUs or better CPU-GPU pairings that achieve higher frame rates in this game.

The ranking relative to other combos is consistent with the measured FPS data. The system's performance at 1080p Ultra (220 FPS) and 4K Ultra (77 FPS) places it in a performance tier that includes other high-end pairings, but the 500th rank indicates that roughly 13.5% of tested combos outperform it. This could be due to newer GPUs or CPUs with higher boost clocks, but the data shows this combo is a strong performer that would satisfy most gamers, especially at 1440p where it averages 143 FPS on Ultra.

The rank of 500 out of 3712 also reflects the balance of the system. The CPU's 90th percentile ranking and GPU's 64th percentile ranking are not perfectly matched—the CPU is relatively stronger than the GPU—but in Doom, this imbalance is less problematic because the game is not heavily CPU-dependent. The combo's rank would likely improve at lower resolutions where the CPU's strength is more fully utilized, and worsen at higher resolutions where the GPU's 64th percentile ranking becomes the limiting factor.
