Doom

How This Combo Ranks

This CPU-GPU pairing lands at rank 2786 out of 3712 tested combos for Doom, placing it in the lower-middle portion of the database. That percentile position—roughly the 25th worst of all recorded configurations—might surprise given the individual hardware credentials, but the data suggests a fundamental mismatch for this specific title. The combo’s ranking reflects how the AMD Ryzen 7 5800X and Intel Arc B580 interact under Doom’s engine, where the GPU’s compute overhead and driver translation layers appear to throttle what is otherwise a strong 8-core processor.

The rank becomes more meaningful when considering the CPU’s aggregate standing. The Ryzen 7 5800X sits at the 81st percentile among all CPUs with an average benchmark score of 29123, yet its nearest rivals in that metric—the Intel Core Ultra 5 135H at 29093 (0.1% ahead), the Intel Xeon Phi 7210 at 29245 (0.4% behind), the Intel Core i5-13500HX at 29270 (0.5% behind), and the AMD Ryzen 5 5600XT at 28940 (0.6% ahead)—all fall within a razor-thin 1% band. This clustering indicates the CPU is not the bottleneck. Meanwhile, the Intel Arc B580’s average benchmark score of 23021 places it at the 68th percentile among GPUs, with its nearest rivals including the AMD Radeon RX 580 2048SP (23061, 0.2% behind), NVIDIA GeForce RTX 2080 (22895, 0.6% ahead), NVIDIA GeForce RTX 3080 (23172, 0.7% behind), and NVIDIA P106-100 (23249, 1% behind). The GPU’s percentile is notably lower than the CPU’s, hinting that the B580 drags the combo down more than the 5800X boosts it.

What the rank does not tell you is whether the pairing is “bad” in absolute terms—Doom at 1080p Ultra still hits 112 FPS average, which is far from unplayable. The 2786th position simply reflects that many other tested combinations achieve higher frame rates in this title, particularly at lower resolutions where the CPU could shine but the GPU’s architectural overhead becomes proportionally more expensive. The data implies that Doom, being a 2016 title with a Vulkan-forward engine, rewards combinations where the GPU handles draw calls efficiently; the B580’s Xe2-HPG architecture, while modern, does not appear to be optimized for this workload in the same way as older NVIDIA or AMD parts.

CPU Role

The AMD Ryzen 7 5800X brings 8 cores and 16 threads based on the Zen 3 architecture, fabricated on TSMC’s 7 nm process with 4,150 million transistors in a 74 mm² die. Its base clock of 3.80 GHz and boost clock of 4.70 GHz, combined with a 32 MB L3 cache, give it substantial headroom for gaming workloads. In Doom specifically, the CPU’s single-threaded performance—evidenced by a 3DMark single-thread score of 943 and a Cinebench R23 single-core score of 1574.5—is more than adequate for the game’s core simulation and physics threads. Multi-threaded scores like Cinebench R23 multicore at 15476 and Geekbench multicore at 11036 show the chip can handle background tasks without stealing frames from the render pipeline.

The data suggests the CPU is not the limiting factor in this combo. At 1080p Low, where GPU load is minimal, the system reaches 186 FPS average—a figure that approaches the practical refresh limits for most monitors and indicates the 5800X can feed the B580 with enough draw calls to saturate even a low-overhead path. Compare this to the 4K Ultra result of just 39 FPS, and the CPU’s role becomes clear: it is waiting on the GPU, not the other way around. The 5800X’s 3DMark 16-thread score of 7586 and max-thread score of 7578 are nearly identical, suggesting that Doom cannot fully utilize all 16 threads, but the 8-core/16-thread configuration still provides redundancy that prevents thread starvation during intense combat scenes.

The CPU’s memory bandwidth of 51.2 GB/s over a dual-channel DDR4 bus is sufficient for this title, as Doom does not exhibit the extreme bandwidth sensitivity seen in some modern simulators. The L3 cache size of 32 MB is particularly relevant for Doom’s level streaming; larger cache hit rates reduce stalls when transitioning between arena sections. The data shows the 5800X’s PassMark single-thread score of 3445 and physics score of 1364 place it well above thresholds where CPU-bound frame drops would appear in this game. In essence, the CPU is doing its job—the measured FPS differences across resolutions and settings scale far more steeply with GPU workload than with CPU load, confirming that the 5800X is a capable partner that is not being pushed to its limits in Doom.

GPU Role

The Intel Arc B580, built on the Xe2-HPG architecture (Battlemage generation), is the more interesting variable in this pairing. With 12 GB of GDDR6 memory on a 192-bit bus delivering 456.0 GB/s bandwidth, it has ample memory capacity and throughput for Doom’s textures and geometry. The GPU’s 2560 shading units, 160 texture mapping units, and 80 raster output pipelines provide a theoretical fill rate of 213.6 GPixel/s and texture rate of 427.2 GTexel/s. Its base and boost clocks are both locked at 2670 MHz, which is a high sustained frequency for a 190 W TDP part, suggesting thermal management is critical to maintaining performance.

However, the benchmark data reveals that the B580’s raw compute does not translate linearly into Doom FPS. The GPU’s 3DMark Steel Nomad DX12 score of 3068 and PassMark G3D score of 15748 indicate mid-range positioning, but Doom’s engine—originally released in 2016 and optimized for Vulkan—appears to introduce driver overhead that the B580’s architecture cannot fully hide. The 13.67 TFLOPS FP32 compute is substantial, yet the measured FPS at 4K High (48 FPS) and 4K Ultra (39 FPS) suggest that the GPU is spending significant cycles on command processing rather than pixel shading. The RT cores (20) and DirectX 12 Ultimate support are irrelevant for Doom, which does not use ray tracing, meaning those hardware units sit idle while the GPU’s traditional raster pipeline carries the entire load.

The GPU’s memory configuration is not the bottleneck—12 GB is far more than Doom needs, even at 4K with Ultra textures. The 456.0 GB/s bandwidth is also sufficient, as evidenced by the fact that frame rates drop proportionally more with settings changes (e.g., from Low to Ultra at 1080p: 186 to 112 FPS) than with resolution changes (e.g., from 1080p Low to 4K Low: 186 to 65 FPS). This pattern points to a compute-bound scenario where the B580’s fixed-function units are the limiting factor, not memory or bandwidth. The GPU’s percentile ranking (68th) and its nearest rivals—including the RTX 2080 and RTX 3080—show that it competes with older high-end parts in synthetic benchmarks, but Doom’s specific workload may expose architectural inefficiencies that those benchmarks do not capture.

Measured FPS Breakdown

The measured FPS data paints a clear picture of scaling across resolutions and settings. At 1080p, the combo delivers 186 FPS on Low, 162 FPS on Medium, 137 FPS on High, and 112 FPS on Ultra. The Medium setting includes min/max values of 137/186 FPS, which exactly match the Low and High averages—a strong indicator that the Medium preset is effectively a blend of the two extremes. The drop from Low to Ultra at 1080p is 74 FPS (a 39.8% reduction), which is substantial but still leaves the game well above 100 FPS for smooth play.

Moving to 1440p, the averages are 120 FPS on Low, 105 FPS on Medium, 88 FPS on High, and 72 FPS on Ultra. The Medium setting shows min/max of 89/120 FPS, again mirroring the Low average at the top end. The relative drop from Low to Ultra is 48 FPS (40%), consistent with the 1080p scaling pattern. However, the absolute frame rates are lower, meaning that 1440p Ultra at 72 FPS is still playable but begins to approach the threshold where competitive players might notice input latency.

At 4K, the numbers fall off sharply: 65 FPS on Low, 57 FPS on Medium (with min/max of 48/65 FPS), 48 FPS on High, and 39 FPS on Ultra. The Low to Ultra drop is 26 FPS (40%), maintaining the same proportional scaling but at a level where even Low settings struggle to hit 60 FPS consistently. The Medium min of 48 FPS is particularly telling—it means that in demanding scenes, the frame rate can dip below 50 FPS, which is noticeable for a fast-paced FPS. The Ultra 4K result of 39 FPS is below the 40 FPS threshold that many players consider the minimum for a playable experience in this genre.

The data shows that the combo’s sweet spot is 1080p, where even Ultra stays above 110 FPS. At 1440p, High (88 FPS) and Medium (105 FPS) provide good experiences, while 4K is only viable on Low settings for a 60 FPS target. The min/max data for Medium settings across all resolutions consistently shows the max matching the Low average and the min matching the next-lower resolution’s Medium or High average, indicating that the Medium preset is a true midpoint in terms of GPU load.

FAQ

Q: Is this combo sufficient for 60 FPS gaming in Doom at 1440p?

A: Yes, according to the measured data. At 1440p, the combo achieves 88 FPS on High and 105 FPS on Medium, both well above 60 FPS. Even Ultra at 1440p hits 72 FPS average, which is above the 60 FPS target.

Q: What is the best resolution for this combo to maintain 144 FPS?

A: The data shows that only 1080p Low achieves 186 FPS, which is above 144 FPS. 1080p Medium at 162 FPS and 1080p High at 137 FPS fall short of 144 FPS, so a 144 Hz monitor would require Low settings at 1080p.

Q: Why does the 4K Ultra result drop to 39 FPS when the GPU has 12 GB of VRAM?

A: The 12 GB VRAM is not the limiting factor; Doom at 4K Ultra does not require that much memory. The 39 FPS result indicates the GPU’s compute throughput is the bottleneck, as the fixed-function units cannot sustain the pixel and texture workload at that resolution and setting combination.

Q: Does the Ryzen 7 5800X bottleneck the Intel Arc B580 in Doom?

A: The data suggests no. At 1080p Low, the combo reaches 186 FPS, which is near the ceiling for many displays and indicates the CPU can feed the GPU adequately. The FPS scaling across resolutions (186 to 65 FPS at Low from 1080p to 4K) correlates more strongly with GPU load than CPU load.

Q: Is the Medium preset a good choice for consistent frame rates?

A: The Medium preset shows min/max values that exactly span the Low and High averages (e.g., 137/186 FPS at 1080p, 89/120 FPS at 1440p, 48/65 FPS at 4K). This suggests Medium provides a balanced experience, but the min FPS can drop to the next resolution’s High level, which may cause noticeable stutters.

Q: How does this combo compare to the GPU’s nearest rivals in terms of overall performance?

A: The B580’s average benchmark score of 23021 is within 1% of the AMD Radeon RX 580 2048SP (23061), NVIDIA GeForce RTX 2080 (22895), NVIDIA GeForce RTX 3080 (23172), and NVIDIA P106-100 (23249). In Doom specifically, the measured FPS at 4K High (48 FPS) is below the 60 FPS threshold, suggesting the B580’s real-world gaming performance may lag its synthetic benchmark standing.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend heavily on the target resolution and refresh rate. For 1080p displays, the High preset at 137 FPS average provides the best balance of visual quality and performance—it stays above 120 FPS, which is responsive enough for most players, and the visual uplift over Medium (162 FPS) is significant. Ultra at 1080p (112 FPS) is also viable, but the 25 FPS penalty over High may not justify the marginal visual improvements in Doom’s fast-paced action.

For 1440p, the Medium preset at 105 FPS is the strongest recommendation. It remains well above 60 FPS and provides enough headroom for demanding scenes (min 89 FPS) to avoid drops below playable levels. High at 1440p (88 FPS) is also acceptable, but the 17 FPS reduction from Medium may be noticeable during intense combat. Ultra at 1440p (72 FPS) is playable but leaves little margin for frame time spikes, making it a risky choice for competitive play.

For 4K, the data clearly recommends the Low preset at 65 FPS. This is the only 4K setting that maintains an average above 60 FPS, which is the minimum for a smooth experience in this genre. Medium at 4K (57 FPS) drops below 60 FPS on average and shows a min of 48 FPS, which will be perceptible as stutter. High (48 FPS) and Ultra (39 FPS) are not recommended for anything beyond casual play or screenshots, as they fall below the playability threshold.

The overall best experience across all resolutions is 1080p High, which delivers 137 FPS with a visual quality setting that balances texture detail and shadow quality. If a user prioritizes frame rate over visuals, 1080p Low at 186 FPS is the maximum performance config, ideal for high-refresh-rate monitors. The Medium preset, while showing consistent scaling, does not offer a unique advantage over Low or High and should be skipped in favor of one of the extremes.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings, revealing the GPU as the primary limiting component. At Low settings, the average FPS goes from 186 at 1080p to 120 at 1440p (a 35.5% reduction) and then to 65 at 4K (a 45.8% reduction from 1440p). This non-linear scaling—where the 1440p to 4K drop is steeper than the 1080p to 1440p drop—is characteristic of a GPU that is hitting a compute wall as pixel count increases. The total reduction from 1080p to 4K is 121 FPS (65.1%), meaning the GPU loses nearly two-thirds of its frame rate when quadrupling the resolution.

At High settings, the scaling is similar: 137 FPS at 1080p, 88 FPS at 1440p (35.8% reduction), and 48 FPS at 4K (45.5% reduction). The consistency of these percentages across settings—roughly 35% for the 1080p to 1440p step and 45% for the 1440p to 4K step—indicates that the limiting factor is the GPU’s raw shading throughput, not memory bandwidth or CPU overhead. If the CPU were the bottleneck, we would expect the FPS to remain flat at lower resolutions before dropping sharply; instead, the FPS drops immediately from 1080p, suggesting the GPU is saturated even at the lowest resolution tested.

The data implies that the Intel Arc B580 is not well-suited for 4K gaming in Doom, regardless of settings, as even Low fails to maintain a comfortable margin above 60 FPS. At 1440p, the GPU is the limiting component but still provides acceptable performance up to High settings. At 1080p, the GPU has enough headroom to push high frame rates, but the CPU’s contribution becomes more apparent—the 186 FPS at 1080p Low likely approaches the engine’s draw call limit for this CPU-GPU combination. The resolution scaling analysis confirms that this combo is best deployed at 1080p or 1440p, with 4K reserved for less demanding titles or for users willing to accept sub-60 FPS averages.
