Doom

The Intel Core i5-14600KF pairs a 14-core, 20-thread Raptor Lake design with a 5.30 GHz boost clock, placing it in the 93rd percentile against all CPUs. Its nearest rival in aggregate benchmarks, the AMD Ryzen 9 5950X, sits just 0.6% behind, while the Intel Core i5-14600K is essentially tied at a 0.4% delta. For a game like Doom, which is not heavily threaded, the single-core performance from that high boost clock matters more than the core count. The CPU’s Cinebench R23 single-core score of 4643 and multi-core score of 32889 indicate it will not bottleneck the GPU in most scenarios, but the data shows that at higher resolutions, the frame rates drop in a way that points to the graphics card being the primary limiter, not the processor. The 24 MB of shared L3 cache and dual-channel memory support are adequate for feeding the GPU, but the benchmark results across resolutions are what define the practical experience.

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

The Core i5-14600KF’s configuration—14 cores and 20 threads—is more than sufficient for Doom’s engine. The game’s frame rates at 1080p are high enough to show that the CPU is doing its job; at Low settings, the combo achieves 183.5 FPS average, which is a strong indicator that the processor can push well past the refresh rates of most monitors. The boost clock of 5.30 GHz is the key spec here, as Doom’s rendering thread benefits from high frequency rather than excessive parallelism. This is reflected in the CPU’s Geekbench single-core score of 2778, which is a solid baseline for gaming workloads.

The CPU’s performance relative to its peers reinforces this. The i5-14600KF trails the AMD EPYC 4345P by only 0.5% in average benchmark score, but the EPYC is a server part with a different focus. Against the Ryzen 9 5950X, the i5 is ahead by 0.6%, which is notable because the 5950X has more cores but a lower boost clock. This suggests that for gaming, the i5’s clock speed compensates for any core-count deficit. The data does not show any CPU-bound stutter or frame pacing issues; the measured FPS at 1080p Low (183.5) versus 1080p Ultra (108.8) shows a 40.7% drop, which is a typical GPU load increase rather than a CPU limitation. In practical terms, this processor will not be the reason for low frame rates in Doom; it has enough headroom to keep the Arc B580 fed.

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

The Intel Arc B580 is built on the Xe2-HPG architecture with a 2670 MHz boost clock and 12 GB of GDDR6 memory on a 192-bit bus, yielding 456.0 GB/s of bandwidth. For Doom, which was released in 2016, the VRAM capacity is more than enough; the game does not require anywhere near 12 GB even at 4K Ultra. The GPU’s 13.67 TFLOPS of FP32 compute and 20 ray tracing cores are modern features that Doom does not heavily utilize, but the raw rasterization power is what drives the measured frame rates. The GPU’s percentile ranking is 66th among all GPUs, and its nearest rival, the NVIDIA GeForce RTX 4060, is only 0.7% ahead in average benchmark score, making the Arc B580 essentially a peer to that card in synthetic tests.

The benchmark results in Doom show the GPU’s behavior clearly. At 1440p High, the combo hits 90 FPS, and at 4K High it drops to 49.3 FPS. The scaling from 1080p High (136.2 FPS) to 1440p High (90 FPS) is a 33.9% reduction, which points to the GPU being the limiting factor as resolution increases. The memory bandwidth of 456.0 GB/s is adequate for this title, and the 12 GB frame buffer will not cause any texture swapping issues. The GPU’s power connector requirement of a single 8-pin and 190 W TDP are modest, but those are not performance metrics. The data indicates that the Arc B580 is a mid-range performer that can handle Doom at high settings up to 1440p, but 4K Ultra is a stretch, as shown by the 39.8 FPS average.

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

The measured FPS across resolutions tells a clear story about where the bottleneck lies. At 1080p Low, the combo produces 183.5 FPS, which is a very high frame rate that suggests the CPU is not holding back the GPU. Moving to 1440p Low, the average drops to 117 FPS—a 36.2% decrease—and at 4K Low, it falls to 65.1 FPS, another 44.4% drop from 1440p. This scaling pattern is characteristic of a GPU-bound scenario; as the pixel count increases, the GPU’s fill rate and shading units become the limiting factor. The CPU’s role diminishes at higher resolutions because the frame time is dominated by the GPU’s rendering work.

The same pattern holds for Ultra settings. At 1080p Ultra, the average is 108.8 FPS; at 1440p Ultra, it is 72.6 FPS (a 33.3% drop); and at 4K Ultra, it is 39.8 FPS (a 45.2% drop from 1440p). These consistent reductions of roughly one-third to one-half per resolution step are the signature of a GPU that is running out of compute or memory bandwidth. The CPU’s 93rd percentile ranking does not change with resolution, but the GPU’s 66th percentile ranking means it is the weaker link. In practical terms, a user targeting 4K on this combo will need to lower settings to Medium (58 FPS) or Low (65.1 FPS) to stay above 60 FPS, while 1440p is comfortable on High (90 FPS). The data shows that the limiting component is unambiguously the Arc B580.

FAQ

A: No. At 1080p Low, the combo hits 183.5 FPS, and at 1080p Ultra it still achieves 108.8 FPS. The CPU’s high boost clock and strong single-core score (4643 in Cinebench R23) keep it ahead of the GPU’s needs.

Q: How does the combo rank among all tested combinations?

A: This combo ranks 1294 out of 1681 tested combinations, placing it in the lower-middle portion of the database. The ranking reflects the GPU’s mid-range positioning rather than the CPU’s high percentile.

How This Combo Ranks

The combo of the Core i5-14600KF and Arc B580 ranks 1294 out of 1681 tested combinations in Doom. This is a low-to-mid ranking, meaning that a significant portion of other combos deliver higher frame rates. The CPU is a strong component—93rd percentile—but the GPU’s 66th percentile pulls the overall ranking down. In the context of the database, this combo is not a top-tier performer; it sits in the bottom 23% of all tested pairs. The ranking makes sense given the GPU’s limitations at 4K, where the combo struggles to maintain playable frame rates on higher presets. However, the ranking does not tell the whole story; at 1080p and 1440p, the combo performs respectably, with 1080p High hitting 136.2 FPS and 1440p High hitting 90 FPS. The rank is more indicative of 4K performance than of the overall experience at lower resolutions.

Settings Recommendations

For the best balance of visual quality and performance, the data points to 1440p High as the sweet spot. At this setting, the combo achieves 90 FPS, which is smooth and visually detailed. Dropping to 1440p Medium only raises the average to 106.3 FPS, a modest gain of 16.3 FPS, while the visual difference between High and Medium is often less noticeable in fast-paced action. If a user prefers maximum fidelity, 1440p Ultra is playable at 72.6 FPS, but the drop from High is significant enough that High is the recommended preset.

At 1080p, the choice depends on the monitor’s refresh rate. For a 144 Hz display, 1080p Medium (161.4 FPS) or Low (183.5 FPS) will keep the frame rate above the refresh ceiling, while High (136.2 FPS) is also suitable for 120 Hz panels. Ultra at 1080p (108.8 FPS) is fine for 60 Hz displays but wastes potential on higher-refresh screens. At 4K, the data shows that only Low (65.1 FPS) consistently clears 60 FPS, with Medium (58 FPS) close but slightly below. For a 4K experience, users should accept Low or Medium settings, as High and Ultra fall to 49.3 and 39.8 FPS, respectively, which are not ideal for a first-person shooter. The overall recommendation is to prioritize 1440p High, as it offers the best combination of fluidity and visual quality without pushing the GPU into uncomfortable territory.
