Doom

Intel Core Ultra 7 270K Plus and Intel Arc B580 deliver a fascinating 1080p-to-4K scaling story in Doom, one that exposes a clear division of labor between the processor and graphics card. The combination ranks 2175th out of 2930 tested combos, placing it in the lower-middle tier of the database, yet the measured frame rates tell a more nuanced story than that raw rank suggests. At 1080p, this pairing is capable of triple-digit performance that exceeds the refresh rate of most monitors, while at 4K it struggles to maintain playable smoothness on higher presets. The data reveals a system that is overwhelmingly GPU-bound at higher resolutions, with the CPU's substantial multi-threaded resources remaining largely untapped. This analysis breaks down exactly where each component matters, which settings provide the optimal experience, and how the frame rate curve bends under resolution scaling.

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

The Intel Core Ultra 7 270K Plus is a 24-core, 24-thread processor based on the Arrow Lake Refresh architecture, built on a 3 nm process by TSMC. It operates with a base clock of 3.70 GHz and a boost clock of 5.50 GHz, backed by a 125 W TDP. The CPU's benchmark profile is exceptional, landing in the 96th percentile among all tested processors, with an average benchmark score of 93785. Its nearest rivals include the Intel Xeon 6520P (score 93786, delta 0%), AMD EPYC 4564P (score 95183, delta -1.5%), AMD EPYC 9175F (score 95615, delta -1.9%), and AMD EPYC 4565P (score 95764, delta -2.1%). The data shows that in synthetic multi-threaded workloads like Cinebench R23, this chip scores 44253, while its single-core score reaches 2439, indicating a strong balance between parallel throughput and per-thread performance.

In Doom, the CPU's role is most visible at 1080p with lower settings, where the frame rate ceiling is high. At 1920x1080 with Low settings, the combo averages 186 FPS, while at 2560x1440 Low it drops to 120 FPS, and at 3840x2160 Low it falls to 65 FPS. This pattern—a 46% drop from 1080p to 1440p, and another 46% drop from 1440p to 4K—indicates that even at Low settings, the GPU becomes the limiting factor as resolution climbs. The CPU's 24 threads and 36 MB of shared L3 cache are more than sufficient for Doom's engine, which rarely scales beyond a handful of threads. The Passmark single-thread score of 5068 and the Cinebench R15 single-core score of 354 suggest that per-core performance is strong, but the game does not appear to demand it. At 1080p Ultra, the combo still manages 112 FPS, proving that the CPU can feed the GPU adequately even under heavy engine load, but the data implies that the processor is never the bottleneck in this pairing—the GPU hits its limits first across all tested configurations.

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

The Intel Arc B580 is built on the Xe2-HPG architecture (Battlemage generation) using a 5 nm process, featuring 12 GB of GDDR6 memory on a 192-bit bus with 456.0 GB/s of bandwidth. Its boost clock is 2670 MHz, and it packs 2560 shading units, 160 TMUs, and 80 ROPs. The GPU's benchmark standing is middling, placing in the 68th percentile among all GPUs with an average score of 23021. Its nearest rivals include the AMD Radeon RX 580 2048SP (score 23061, delta -0.2%), NVIDIA GeForce RTX 2080 (score 22895, delta 0.6%), NVIDIA GeForce RTX 3080 (score 23172, delta -0.7%), and NVIDIA P106-100 (score 23249, delta -1%). The 3DMark Steel Nomad DX12 score of 3068 and Passmark G3D score of 15748 provide context for its rasterization capabilities, which are adequate for Doom but not class-leading.

The GPU's 12 GB VRAM is ample for Doom, a 2016 title that does not require massive memory pools even at 4K Ultra, so capacity is not a limiting factor. Instead, the data shows that raw compute throughput dictates performance. At 4K Ultra, the combo averages only 39 FPS, while at 4K High it reaches 48 FPS, and at 4K Medium it hits 57 FPS. The scaling from Ultra to Medium at 4K—a 46% improvement in frame rate—indicates that the GPU's shading units and ROPs are heavily taxed by the highest preset. The 4K Low result of 65 FPS, which is 67% higher than 4K Ultra, further confirms that the GPU is the primary constraint. The Arc B580's FP32 throughput of 13.67 TFLOPS and pixel rate of 213.6 GPixel/s are the specifications that likely determine these results, as Doom's Vulkan renderer leans on these metrics. The GPU's 20 RT cores are irrelevant for this title, and its 12 GB VRAM never becomes a bottleneck, so the measured FPS curve is a direct reflection of its traditional rasterization performance.

Settings Recommendations — which preset gives the best experience per the measured rows

The measured data offers a clear hierarchy of presets across all three resolutions, and the optimal choice depends heavily on the target display. At 1920x1080, every preset exceeds 100 FPS, with Low at 186, Medium at 162, High at 137, and Ultra at 112. For a 144 Hz monitor, Ultra at 112 FPS falls short, but High at 137 FPS is close, and Medium at 162 FPS comfortably exceeds it. Since the leap from Medium to Ultra costs 50 FPS (from 162 to 112), the data suggests that High is the sweet spot for 1080p, offering 137 FPS while preserving visual fidelity. The min FPS at Medium is 137, which matches the average of High, indicating that even the lower-bound frame times at Medium are acceptable.

At 2560x1440, the situation tightens. Low averages 120 FPS, Medium 105 FPS, High 88 FPS, and Ultra 72 FPS. For a 60 Hz display, even Ultra is playable, but for higher refresh rates, Medium at 105 FPS is the best balance. High at 88 FPS is smooth but not ideal for 144 Hz, and Ultra at 72 FPS sacrifices too much responsiveness. The min FPS at Medium is 89, which is still above 60, so the experience remains consistent. At 3840x2160, the recommendations shift to prioritize playability. Low averages 65 FPS, which is playable, while Medium drops to 57 FPS, High to 48 FPS, and Ultra to 39 FPS. For a 4K display, Low is the only preset that consistently holds above 60 FPS, though Medium at 57 FPS is close and offers better visuals. The measured data indicates that Medium at 4K is the best compromise, as it stays above 48 FPS (the min), which is still smooth enough for single-player action, whereas High and Ultra dip into the 30-40 FPS range that is generally considered suboptimal. Across all resolutions, the pattern is consistent: Medium provides the best frame rate per preset step, while Ultra offers diminishing returns that are not justified by the performance penalty.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core Ultra 7 270K Plus and Intel Arc B580 ranks 2175th out of 2930 tested combos in Doom, placing it in the 74th percentile of all pairings. This rank is surprisingly low given the CPU's 96th percentile standing and the GPU's 68th percentile, which suggests that the GPU drags down the overall result. The data implies that many combos with weaker CPUs but stronger GPUs outperform this pairing in Doom, because the game is not CPU-limited. The nearest CPU rivals—such as the Intel Xeon 6520P, which scores within 0% of the Ultra 7 270K Plus—would likely produce similar results when paired with a comparable GPU, but the Arc B580's performance tier is the deciding factor. The GPU's nearest rivals, including the RTX 2080 and RTX 3080, have average scores within 1% of the Arc B580, yet those GPUs are older generations with different architectural strengths; in Doom, the data shows that the Arc B580's raster performance is sufficient for 1080p but not for 4K Ultra.

The rank of 2175 out of 2930 means that 755 combos perform worse, but it also means that 2174 combos perform better, which is a stark indictment of the GPU's ceiling in this title. The CPU's Passmark multithread score of 68574 and Cinebench R23 multicore score of 44253 are wasted potential in Doom, as the engine does not leverage such parallelism. The combo's rank is therefore a reflection of the GPU's limitations rather than the CPU's capabilities. This is evident when examining the frame rate scaling: at 1080p Low, the combo hits 186 FPS, which is competitive with higher-ranked systems, but at 4K Ultra, the 39 FPS result is near the bottom of the distribution. The data suggests that if the same CPU were paired with a GPU in the 90th percentile, the rank would improve dramatically, but as it stands, the Arc B580 holds this combo back in Doom's most demanding settings.

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

The FPS drop from 1080p to 4K is steep and consistent across all settings, which is a clear indicator of GPU-bound performance. At Low settings, the average FPS falls from 186 at 1080p to 120 at 1440p (a 35% drop) and then to 65 at 4K (a 46% drop from 1440p). At Medium settings, the sequence is 162 to 105 to 57, with a 35% drop from 1080p to 1440p and a 46% drop from 1440p to 4K. High settings show 137 to 88 to 48, with a 36% and 45% drop, respectively. Ultra settings show 112 to 72 to 39, with a 36% and 46% drop. The consistency of these percentages—roughly 35-36% from 1080p to 1440p and 45-46% from 1440p to 4K—is the signature of a GPU that is scaling with pixel count, not a CPU that is hitting a thread limit.

If the CPU were the bottleneck, the FPS would plateau at lower resolutions, but instead it continues to rise all the way to 186 FPS at 1080p Low, indicating headroom. The pixel count quadruples from 1080p to 4K, and the FPS drops by roughly 65-70% across all presets (e.g., 186 to 65 on Low, 112 to 39 on Ultra), which is more than the linear scaling expected if the GPU were fully utilized. This suggests that the Arc B580's memory bandwidth (456.0 GB/s) and shading unit count (2560) are insufficient to maintain fill rate at 4K, and the GPU becomes the limiting component. The CPU's 36 MB L3 cache and 115.2 GB/s memory bandwidth are irrelevant at 4K, as the GPU's 192-bit bus is the constraining factor. The data reveals that this combo is designed for 1080p and 1440p gaming, with 4K being a stretch goal that requires significant setting reductions.
