Doom

The AMD Ryzen 7 7800X3D paired with the Intel Arc B580 delivers a compelling 1080p and 1440p experience in Doom, but the data clearly shows the GPU becoming the primary constraint as resolution climbs. At 1080p with Low settings, the combination produces 183.1 FPS, which drops to 135.8 FPS at High settings. Moving to 1440p, the same Low preset yields 117.5 FPS, while High settings still manage 89.6 FPS. The real inflection point occurs at 4K, where even Low settings only reach 63.9 FPS, and Ultra falls to 36.9 FPS. This scaling pattern indicates the CPU has ample headroom at lower resolutions, but the Arc B580’s rendering throughput becomes the limiting factor as pixel count increases.

Resolution Scaling

The measured FPS deltas between resolutions expose the system’s bottleneck behavior with clarity. From 1080p Low to 1440p Low, performance drops by 65.6 FPS (from 183.1 to 117.5), a 35.8% reduction. The same settings step from 1440p to 4K shows a steeper decline of 53.6 FPS (from 117.5 to 63.9), a 45.6% loss. This accelerating degradation pattern is classic GPU-bound behavior. The Ryzen 7 7800X3D, with its 96 MB of shared L3 cache and 16 threads, is clearly not the limiting factor at 1080p, where the 183.1 FPS Low result suggests the CPU could push even higher if the GPU allowed.

At High settings, the resolution scaling tells a similar story. 1080p High delivers 135.8 FPS, 1440p High drops to 89.6 FPS (a 34% reduction), and 4K High falls to 48 FPS (a 46.4% reduction from 1440p). The consistency of these percentage drops across presets reinforces that the GPU is the dominant constraint at resolutions above 1080p. The Ultra preset shows the most dramatic scaling: 109.2 FPS at 1080p, 74.5 FPS at 1440p, and just 36.9 FPS at 4K. The 4K Ultra result is particularly telling, as it falls below the 48 FPS High result at the same resolution, demonstrating that the Arc B580’s 13.67 TFLOPS of FP32 performance is insufficient for maxed-out 4K gaming in this title.

The data suggests that players targeting 4K should expect playable but not fluid performance, with Low settings being the only preset that clears 60 FPS at that resolution. The 63.9 FPS 4K Low result is technically above the 60 FPS threshold, but the margin is thin. For 1440p, the system offers a wide range of viable options, with every preset except Ultra clearing 89 FPS. The 1080p results are uniformly excellent, with even Ultra settings maintaining 109.2 FPS.

Settings Recommendations

The measured data provides clear guidance on optimal preset selection for each resolution. At 1080p, the High preset at 135.8 FPS represents the best balance of visual fidelity and performance, as it sits within 26% of the Low preset’s 183.1 FPS while offering substantially better image quality. The Ultra preset at 109.2 FPS is also viable, but the 24.3% performance penalty over High (26.6 FPS) may not justify the marginal visual gains for competitive play.

For 1440p, the Medium preset at 106 FPS emerges as the sweet spot. It delivers 18.3% more performance than High (89.6 FPS) and 42.3% more than Ultra (74.5 FPS), while remaining only 9.8% below the Low preset’s 117.5 FPS. The Medium preset’s 106 FPS result is comfortably above the 90 FPS threshold that most players consider smooth for fast-paced shooters, making it the recommended choice for 1440p monitors.

At 4K, the options are more constrained. The Low preset at 63.9 FPS is the only setting that maintains playability, and even this result is only 6.5% above the 60 FPS minimum. The Medium preset at 57.6 FPS falls below that threshold, and High at 48 FPS and Ultra at 36.9 FPS are increasingly compromised. Given these measurements, 4K players should use Low settings and accept the visual trade-offs, or consider lowering the resolution to 1440p where Medium settings provide a far more enjoyable experience. The data does not support any preset above Low at 4K for a satisfying gameplay experience.

Q: Which resolution offers the widest range of usable presets?

A: At 2560x1440, all four presets produce playable frame rates, ranging from 74.5 FPS (Ultra) to 117.5 FPS (Low). This is the only resolution where every preset exceeds 70 FPS.

Q: Is the Ryzen 7 7800X3D the limiting factor in 4K performance?

A: No. The data shows that 4K performance drops drastically across all presets, with the GPU’s rendering capability being the constraint. The CPU’s 3DMark 16-thread score of 7980 and Cinebench R23 multicore score of 29149 indicate ample processing headroom for this title.

Measured FPS Breakdown

The complete measured FPS table reveals consistent performance hierarchy across resolutions. At 1920x1080, the Low preset leads with 183.1 FPS, followed by Medium at 158.5 FPS, High at 135.8 FPS, and Ultra at 109.2 FPS. The gap between Low and Medium is 24.6 FPS (15.5% reduction), while the gap between Medium and High is 22.7 FPS (14.3% reduction), and between High and Ultra is 26.6 FPS (19.6% reduction). These relatively even steps suggest the GPU scales predictably with graphical load.

At 2560x1440, the pattern shifts slightly. Low produces 117.5 FPS, Medium drops to 106 FPS (9.8% reduction), High falls to 89.6 FPS (15.5% reduction from Medium), and Ultra reaches 74.5 FPS (16.9% reduction from High). The percentage reductions between presets increase as settings rise, indicating that the Ultra preset’s additional effects impose a proportionally larger load at this resolution.

The 3840x2160 results show the most compressed range. Low delivers 63.9 FPS, Medium 57.6 FPS (9.9% reduction), High 48 FPS (16.7% reduction from Medium), and Ultra 36.9 FPS (23.1% reduction from High). The widening percentage gaps at 4K, particularly the 23.1% drop from High to Ultra, demonstrate the GPU’s struggle with the highest fidelity settings at this pixel density. The absolute difference between Low and Ultra at 4K is 27 FPS, which represents a 42.3% performance penalty for maximum visual quality.

Across all resolutions, the Low-to-Ultra performance delta is consistent in absolute terms: 73.9 FPS at 1080p, 43 FPS at 1440p, and 27 FPS at 4K. This diminishing absolute difference with increasing resolution reinforces that the GPU becomes progressively more saturated, leaving less headroom for settings changes to impact frame rates.

GPU Role

The Intel Arc B580’s specifications directly explain the measured performance patterns. With 12 GB of GDDR6 memory on a 192-bit bus providing 456.0 GB/s of bandwidth, the GPU has sufficient memory capacity for Doom at all tested resolutions. The 2560 shading units and 80 ROPs deliver a pixel rate of 213.6 GPixel/s and a texture rate of 427.2 GTexel/s, which translate to the frame rates observed. The base and boost clocks are both 2670 MHz, indicating a fixed clock behavior under load.

The GPU’s benchmark results contextualize its gaming performance. The 3DMark Steel Nomad DX12 score of 3068 and PassMark G3D score of 15748 place it in the 66th percentile of all GPUs. Its Geekbench Vulkan score of 109672 is notably higher than the OpenCL score of 92821, suggesting the Xe2-HPG architecture performs well with Vulkan APIs, which is relevant since Doom uses Vulkan. The PassMark DirectX 11 score of 128 and DirectX 12 score of 76 indicate that the GPU handles older APIs less efficiently, but this does not impact the tested game.

The Arc B580’s 13.67 TFLOPS of FP32 compute and 27.34 TFLOPS of FP16 (2:1 ratio) provide the raw processing power for the observed frame rates. The 20 RT cores are present but not relevant to Doom’s rendering. The GPU’s 190 W TDP and dual-slot design suggest it maintains consistent clocks under sustained load, which is consistent with the stable FPS measurements. The 19.6 billion transistors on a 272 mm² die at 5 nm represent a dense implementation that delivers the measured performance.

The memory configuration is particularly relevant at 4K. The 456.0 GB/s bandwidth and 12 GB capacity are sufficient for the 4K Ultra preset, as evidenced by the playable (though not high) 36.9 FPS result. The GPU’s 66th percentile ranking among all GPUs and its benchmark proximity to the RTX 4060 (0.7% lower score) indicate it is a mid-range performer, which aligns with the observed Doom results that show strong 1080p performance but diminishing returns at higher resolutions.
