Doom

The Intel Core i5-12600KF paired with the Intel Arc B580 delivers a solid 1080p and 1440p experience in Doom, but the data shows a clear ceiling at 4K. The measured FPS across resolutions reveals a system that is heavily GPU-bound at higher pixel counts, while the CPU has ample headroom to push frames at lower resolutions.

Resolution Scaling

The frame rate drops from 1080p to 4K are steep and consistent, indicating that the Intel Arc B580 is the primary limiting factor as resolution increases. At High settings, the average FPS falls from 134.8 at 1920x1080 to 87.5 at 2560x1440, a reduction of 47.3 FPS. Pushing further to 3840x2160 brings the average down to 44.9 FPS, a 66.8% decrease from the 1080p figure. This pattern holds across all settings presets, confirming that the GPU's rendering throughput is the bottleneck at 4K.

At Low settings, the scaling is even more pronounced. The system achieves 183.3 FPS at 1080p, but this drops to 120.5 FPS at 1440p and then plummets to 66.1 FPS at 4K. The 4K Low result is actually lower than the 1080p Medium result of 158.9 FPS, illustrating how dramatically pixel count taxes the Arc B580. The gap between 1440p and 4K is consistently larger than the gap between 1080p and 1440p, which suggests the GPU's memory bandwidth of 456.0 GB/s and 192-bit bus are saturated at the higher resolution.

The data indicates that for smooth 4K gameplay, settings must be dropped significantly. The jump from Low to High at 4K costs 21.2 FPS, while the same settings change at 1080p costs 48.5 FPS. This nonlinear scaling points to the GPU being the limiting component, as the CPU's performance headroom is not the constraint here.

GPU Role

The Intel Arc B580, built on the Xe2-HPG architecture with a 5 nm process, shows its strengths and limitations in Doom. Its 12 GB of GDDR6 memory on a 192-bit bus provides 456.0 GB/s of bandwidth, which proves sufficient for 1080p and 1440p but struggles at 4K Ultra. The core clocks are locked at a base of 2670 MHz and a boost of 2670 MHz, which is a modest boost behavior that keeps power draw predictable at a 190 W TDP.

The GPU's benchmark scores place it in the 66th percentile among all GPUs, with an average benchmark score of 23021. Its nearest rival, the NVIDIA GeForce RTX 4060, scores 23181, which is 0.7% higher, while the AMD Radeon 760M scores 22999, 0.1% lower. These close margins suggest the Arc B580 is competitive with these mainstream cards, and the measured FPS in Doom reflects this positioning.

At 1080p Ultra, the Arc B580 produces 108.4 FPS, which is playable but not exceptional for a game from 2016. The 2560x1440 Ultra result of 75 FPS is a solid figure, but the 4K Ultra result of 40.6 FPS is below the 60 FPS threshold many players target. The GPU's 13.67 TFLOPS of FP32 compute and 20 ray tracing cores do not translate into a strong 4K showing, as the data shows a 53.6% drop from 1440p to 4K at Ultra settings.

The pixel rate of 213.6 GPixel/s and texture rate of 427.2 GTexel/s are the key specs for Doom's fast-paced rendering. At lower resolutions, these rates are sufficient, but the 4K results indicate they are not enough to maintain fluid frame rates. The GPU's 2560 shading units and 80 ROPs are the hardware that ultimately limits 4K performance.

CPU Role

The Intel Core i5-12600KF is a 10-core, 16-thread processor from the Alder Lake architecture, with a base clock of 3.70 GHz and a boost clock of 4.90 GHz. Its 20 MB of shared L3 cache and support for DDR4 and DDR5 memory give it robust bandwidth for feeding the GPU. The processor's benchmark scores are strong: it sits in the 84th percentile among all CPUs with an average score of 27827, and its Cinebench R23 multicore score of 23444 is a solid result.

The CPU's nearest rivals include the Intel Core i9-10900K (scoring 27829, a 0% delta) and the Intel Core i5-12600K (scoring 27851, a -0.1% delta). These nearly identical scores indicate that the i5-12600KF is performing at the same level as these alternatives, meaning any FPS differences in Doom are attributable to the GPU, not the CPU.

In Doom, the CPU's role is to feed the GPU with draw calls and physics calculations. At 1080p Low, the system reaches 183.3 FPS, which is likely near the CPU's limit for this game. The fact that 1080p Medium produces 158.9 FPS and 1080p High produces 134.8 FPS shows that the CPU is not the bottleneck at these settings; the GPU is doing the heavy lifting. The 3dmark single-thread score of 1016 and passmark single-thread score of 3925 indicate strong per-core performance, which is critical for a game like Doom that relies on a few main threads.

The data suggests that the i5-12600KF has headroom even at 1440p. The jump from 1440p High (87.5 FPS) to 1080p High (134.8 FPS) is a 47.3 FPS gain, which is much larger than the CPU's performance delta would suggest. This confirms that the GPU is the limiting component at all resolutions tested, and the CPU is not holding back the system.

How This Combo Ranks

This specific combination of the Intel Core i5-12600KF and Intel Arc B580 ranks 1301 out of 1681 tested combos in Doom. This places it in the lower-middle portion of the database, which is expected given the GPU's 66th percentile standing and the game's age. The ranking suggests that while this combo is capable of decent frame rates, many other pairings outperform it.

The benchmark results show that this combo is best suited for 1080p and 1440p gaming. At 1080p High, it achieves 134.8 FPS, which is well above the 60 FPS standard. The 4K results, however, are below that threshold, with the best 4K setting (Low) only reaching 66.1 FPS. The rank of 1301 reflects this mixed performance profile, as the combo cannot deliver a consistently high frame rate across all resolutions.

The deltaPct values from the nearest rivals show that the CPU and GPU are each close to their competitors. The i5-12600KF is essentially tied with the i9-10900K, and the Arc B580 is within 0.7% of the RTX 4060. This means that the combo's rank is not due to a weak component, but rather the overall market position of these parts relative to more powerful alternatives.

Measured FPS Breakdown

At 1920x1080, the combo delivers strong results across all settings. Low settings produce 183.3 FPS, Medium produces 158.9 FPS, High produces 134.8 FPS, and Ultra produces 108.4 FPS. The gap between Low and Ultra is 74.9 FPS, showing that the GPU has enough headroom at this resolution to absorb the extra graphical load.

At 2560x1440, the frame rates remain playable. Low settings yield 120.5 FPS, Medium yields 103.7 FPS, High yields 87.5 FPS, and Ultra yields 75 FPS. The drop from 1080p to 1440p is significant, but even Ultra at 75 FPS is smooth. The scaling from High to Ultra at this resolution costs 12.5 FPS, which is a reasonable trade for the visual upgrade.

At 3840x2160, the performance drops below the 60 FPS threshold for most settings. Low produces 66.1 FPS, Medium produces 58.4 FPS, High produces 44.9 FPS, and Ultra produces 40.6 FPS. The difference between Low and Medium is 7.7 FPS, while the difference between High and Ultra is only 4.3 FPS, indicating that the GPU is severely limited at this resolution regardless of the settings chosen.

The overall trend is clear: this combo is a 1080p and 1440p performer, not a 4K solution. Players targeting 4K will need to accept Low settings for a playable experience, while those at 1080p can enjoy Ultra settings with frame rates above 100 FPS.
