Doom

The AMD Ryzen 9 7900X paired with the Intel Arc B580 delivers a solid 1080p and 1440p experience in Doom, but struggles to maintain smooth frame rates at 4K with higher presets. The measured data shows a clear performance hierarchy across the three tested resolutions, with the GPU becoming the primary limiting factor as resolution increases.

Measured FPS Breakdown

At 1920x1080, the combo produces excellent frame rates across all settings. The Low preset delivers an average of 185.5 FPS, which is the highest recorded for this combination. Medium settings drop to 159.3 FPS average, while High still maintains a very strong 137.1 FPS average. The most demanding Ultra preset produces an average of 111.2 FPS, which remains well above the 60 FPS playable threshold. The scaling from Low to Ultra at 1080p shows a performance drop of roughly 40% from the peak, indicating that the GPU is handling most of the rendering workload efficiently at this resolution.

Moving to 2560x1440, the frame rates remain robust but show a noticeable decline from 1080p. The Low preset averages 120.6 FPS, Medium drops to 107.1 FPS, and High produces 90.4 FPS. Ultra settings at 1440p average 71.7 FPS, which still clears the 60 FPS threshold with a comfortable margin. The transition from 1080p to 1440p costs roughly 35% performance at the Low preset, but the Ultra preset sees a smaller relative drop of about 35.5%, suggesting that the Arc B580’s memory bandwidth and rasterization throughput are being tested more heavily at this resolution.

At 3840x2160, the picture changes significantly. The Low preset averages 62.8 FPS, just barely exceeding the 60 FPS playable threshold. Medium settings average 55.8 FPS, High drops to 45.9 FPS, and Ultra falls to 41.9 FPS. The gap between Low and Ultra at 4K is about 33%, but more importantly, only the Low preset remains playable. The data shows that 4K resolution imposes a severe load on the Intel Arc B580, with the 12 GB GDDR6 memory and 456.0 GB/s bandwidth being pushed to their limits.

Best Settings per Resolution

For 1920x1080, the Ultra preset is the best choice, delivering an average of 111.2 FPS. This is not just playable—it is smooth enough for fast-paced FPS gameplay with maximum visual fidelity. The Ryzen 9 7900X provides ample CPU headroom at this resolution, and the Arc B580 has enough raw throughput to handle Ultra settings without compromising the experience.

At 2560x1440, Ultra is again the best settings preset, with an average of 71.7 FPS. This clears the 60 FPS threshold by a healthy 11.7 FPS, making it a viable option for players who prioritize visual quality over maximum frame rates. The gap between Ultra and High at this resolution is substantial—71.7 FPS versus 90.4 FPS—so players who prefer higher refresh rates could drop to High for a smoother experience, but the data confirms that Ultra is technically playable.

For 3840x2160, the only playable preset is Low, averaging 62.8 FPS. This is a narrow margin above the 60 FPS threshold, leaving little headroom for demanding scenes or combat-heavy moments. Medium settings at 55.8 FPS fall short of playability, and High and Ultra are significantly off the mark. Players seeking 4K performance should stick with Low settings or consider lowering the resolution.

CPU and GPU Roles

The benchmark data reveals a clear division of labor between the Ryzen 9 7900X and the Arc B580 across resolutions. At 1920x1080, the CPU has significant influence, as evidenced by the large frame rate differences between presets. The Ryzen 9 7900X, with 12 cores and 24 threads based on Zen 4 architecture, provides enough processing power to feed the GPU efficiently at lower resolutions. The 185.5 FPS Low preset result at 1080p indicates that the CPU is not a bottleneck, and the GPU is able to stretch its legs.

At 2560x1440, the balance shifts. The frame rates drop across all presets proportionally to the increase in pixel count, but the relative differences between presets remain similar to 1080p. This suggests that both the CPU and GPU are still working in tandem, with the GPU beginning to take on more responsibility for the rendering load. The 71.7 FPS Ultra result at 1440p versus the 111.2 FPS at 1080p represents a 35.5% drop, which is consistent with the increased pixel workload rather than a CPU limitation.

The 3840x2160 results show the GPU becoming the dominant factor. The Ryzen 9 7900X’s capabilities are largely irrelevant at this resolution because the Arc B580 cannot maintain high frame rates regardless of CPU performance. The 41.9 FPS Ultra result at 4K versus the 62.8 FPS Low result highlights that the GPU’s shading units, texture units, and raster operations are saturated. The Arc B580’s 2560 shading units and 80 ROPs are insufficient for 4K Ultra in Doom, and the CPU has no way to compensate for this hardware limitation.

How This Combo Ranks

The combo ranks 2817 out of 3712 tested combinations in Doom, placing it in the lower-middle portion of the database. This rank reflects the Arc B580’s overall GPU performance, which sits at the 68th percentile among all GPUs, rather than the CPU’s strength. The Ryzen 9 7900X ranks in the 91st percentile among all CPUs, indicating that the processor is far more capable than the graphics card for this game.

The ranking disparity makes sense given the measured FPS data. At 1080p and 1440p, the combo delivers respectable performance, but the 4K results drag the overall ranking down. Many competing combinations with stronger GPUs or more balanced pairings achieve higher ranks. The Arc B580’s passmark G3D score of 15748 and 3DMark Steel Nomad score of 3068 are moderate, and the GPU’s overall benchmark score of 23021 places it in a competitive but not top-tier segment.

Similar Performance Alternatives

The nearest rivals for the Ryzen 9 7900X provide context for its CPU performance. The AMD EPYC 7313P scores 53206, which is 0.2% lower than the Ryzen 9 7900X’s average benchmark score of 53288. The Intel Xeon Phi 7290 scores 53469, or 0.3% higher, while the Intel Xeon 634 scores 52974, which is 0.6% lower. The Intel Core i7-14700F scores 53620, putting it 0.6% ahead. These differences are negligible in gaming scenarios, meaning any of these CPUs would behave similarly when paired with the Arc B580 in Doom.

For the GPU, the nearest rivals show tight competition. The AMD Radeon RX 580 2048SP scores 23061, just 0.2% higher than the Arc B580’s 23021 average. The NVIDIA GeForce RTX 2080 scores 22895, which is 0.6% lower, while the RTX 3080 scores 23172, or 0.7% higher. The NVIDIA P106-100 scores 23249, putting it 1% ahead. These deltas are small enough that swapping to any of these GPUs would produce nearly identical frame rates in Doom. The RTX 2080 and RTX 3080, despite being older architectures, offer comparable performance to the Arc B580 in this specific benchmark context.

The Verdict

This PC can run Doom effectively at 1080p and 1440p, but 4K requires significant compromises. At 1920x1080, every preset from Low to Ultra clears the 60 FPS threshold, with Ultra averaging 111.2 FPS. This makes the combo well-suited for high-refresh-rate monitors at 1080p, providing a smooth and responsive experience without needing to lower visual quality.

At 2560x1440, the Ultra preset averages 71.7 FPS, confirming that this resolution is fully playable with maximum settings. Players who prefer even higher frame rates can drop to High for 90.4 FPS or Medium for 107.1 FPS, but the data shows that Ultra is viable. The Ryzen 9 7900X ensures that CPU-bound scenarios do not cause stuttering or frame drops, and the Arc B580 handles the rendering load adequately.

At 3840x2160, only the Low preset is playable, averaging 62.8 FPS. This is a marginal pass, and the narrow margin means that demanding scenes could push frame rates below 60 FPS. Medium and above are not recommended for 4K gameplay. The verdict based on the data is that this combination is best suited for 1080p and 1440p gaming, with 4K reserved for players who are willing to accept Low settings and occasional frame rate dips. For a game like Doom, which benefits from high frame rates, the 1440p Ultra experience is the sweet spot for this hardware pairing.
