Doom

The Intel Core i7-14700KF paired with the Intel Arc B580 delivers a performance profile that is highly dependent on resolution and graphics preset. At 1920x1080, the combination is exceptionally strong, with even the Ultra preset producing an average of 112 FPS. Moving to 2560x1440, the system remains fluid, maintaining an average of 72 FPS on Ultra. However, at 3840x2160, the GPU becomes the limiting factor, and only the Low preset clears the 60 FPS threshold, with an average of 65 FPS. The data shows a consistent pattern: the Arc B580 provides ample headroom for high-refresh 1080p and solid 1440p gaming, but 4K requires significant settings reductions.

Measured FPS Breakdown

The benchmark results for Doom provide a clear, resolution-by-resolution view of performance. At 1920x1080, the frame rates are consistently high across all presets. The Low preset yields an average of 186 FPS, while the Medium preset averages 162 FPS, with a minimum of 137 FPS and a maximum of 186 FPS. The High preset drops to an average of 137 FPS, and the Ultra preset, while the most demanding, still produces a robust average of 112 FPS. At this resolution, the frame rate is so high that the minimum and maximum values for most presets are not recorded, indicating that the bottleneck is rarely the GPU.

At 2560x1440, the performance scales down predictably but remains playable across the board. The Low preset averages 120 FPS, and the Medium preset averages 105 FPS, with a recorded minimum of 89 FPS and a maximum of 120 FPS. The High preset delivers an average of 88 FPS, and the Ultra preset, while more demanding, still maintains a solid average of 72 FPS. This resolution represents a sweet spot for the hardware, as all presets exceed the 60 FPS playability threshold, and the Ultra preset remains viable for a smooth experience.

At 3840x2160, the picture changes dramatically. The Arc B580’s 12 GB of memory and 192-bit bus are pushed to their limits. The Low preset is the only one that averages above 60 FPS, with a mean of 65 FPS. The Medium preset drops to an average of 57 FPS, with a minimum of 48 FPS and a maximum of 65 FPS, indicating noticeable frame dips. The High preset averages 48 FPS, and the Ultra preset falls to an average of 39 FPS. These numbers show that 4K gaming is only viable with the lowest settings, and even then, the frame rate is not consistently high.

CPU and GPU Roles

The data reveals a clear division of labor between the Intel Core i7-14700KF and the Intel Arc B580. At 1920x1080, the CPU’s strong single-threaded performance (a Cinebench R23 single-core score of 6235) is sufficient to feed the GPU. The frame rates scale almost linearly with preset reductions, suggesting the GPU is the primary constraint, but the CPU is never the bottleneck. The gap between Low (186 FPS) and Ultra (112 FPS) is 74 FPS, which is a direct result of the GPU’s shading load.

At 2560x1440, the CPU’s role diminishes further as the GPU takes on more work. The scaling from Low (120 FPS) to Ultra (72 FPS) is a 48 FPS drop, which is less severe than at 1080p, indicating that the GPU is now the dominant factor. The i7-14700KF, with its 20 cores and 28 threads, remains far from being a limiting factor, as its Passmark multithread score of 52425 shows it has ample headroom for gaming workloads.

At 3840x2160, the GPU is unequivocally the bottleneck. The CPU’s performance is almost irrelevant at this resolution, as the Arc B580’s raw throughput (13.67 TFLOPS FP32) is insufficient to maintain high frame rates on demanding presets. The drop from Low (65 FPS) to Ultra (39 FPS) is a 26 FPS decrease, showing that the GPU’s fill rate and shading units are the limiting factor. The data suggests that upgrading the GPU would yield significant gains at 4K, while the CPU would be an afterthought.

Best Settings per Resolution

For achieving a consistent 60 FPS or higher, the best settings vary by resolution. At 1920x1080, the Ultra preset is the most demanding option that remains playable, with an average FPS of 112. This provides a substantial margin over the 60 FPS threshold, ensuring smooth gameplay even in intense scenes.

At 2560x1440, the Ultra preset also holds up, with an average of 72 FPS. While this is above the 60 FPS mark, the margin is narrower than at 1080p, so users who prefer a higher frame rate buffer might consider the High preset, which averages 88 FPS. However, the data confirms that Ultra is the best playable setting at this resolution.

At 3840x2160, the only playable setting is Low, with an average of 65 FPS. This is the single preset that clears the 60 FPS threshold. The Medium preset falls short at 57 FPS, making it unsuitable for a strict 60 FPS target. The data indicates that 4K gaming on this hardware requires sacrificing visual fidelity to maintain playability.
