Doom

How This Combo Ranks

The pairing of the AMD Ryzen 9 9900X with the AMD Radeon RX 580 lands in the bottom tier of tested configurations for Doom, ranking 1553rd out of 1681 combos. This places it in the 8th percentile of all possible pairings, a position driven almost entirely by the graphics card rather than the processor. The CPU is a top-tier part—sitting in the 94th percentile of all CPUs—but the GPU sits at just the 53rd percentile, and in a fast-paced FPS like Doom, that imbalance shows clearly in the frame rate data.

The benchmark results indicate a system that can handle the game at 1080p with decent fluidity at lower presets, but one that struggles to maintain playable frame rates at higher resolutions or with maxed-out settings. The combo's rank reflects a fundamental mismatch: a processor capable of feeding frames far faster than the graphics card can render them. The RX 580's average benchmark score of 13559 places it in a dead heat with the NVIDIA GeForce GTX 570 (deltaPct 0) and the GTX 950 (deltaPct 0.1), while it sits just 1.1% ahead of the AMD Radeon Pro 455. This is legacy hardware from 2017, and Doom's demanding Vulkan-based engine exposes its age.

The data shows a clear ceiling: at 4K, even the lowest settings fail to hit 40 FPS, and at 1440p the card only manages a playable 52 FPS on High. The 1080p results are the only place where this combination approaches what modern gamers would consider smooth, and even then, the Ultra preset drops to 60.6 FPS. This rank is not a reflection of the CPU's capability—the Ryzen 9 9900X is among the fastest consumer processors available—but rather a warning that pairing a high-end 2024 processor with a 2017 mid-range GPU creates a bottleneck that no amount of CPU headroom can overcome.

FAQ

Q: Is this combination capable of running Doom smoothly at 1080p?

A: Yes, at 1080p the combo achieves 74.3 FPS on High settings and 87.5 FPS on Medium, with Low settings reaching 103.3 FPS. The Ultra preset drops to 60.6 FPS, which is still technically playable but close to the edge of what most users consider smooth.

Q: How does the Ryzen 9 9900X compare to its closest rivals in general CPU performance?

A: The Ryzen 9 9900X has an average benchmark score of 54450, placing it 0.7% ahead of the Intel Core i7-14700F (54097) and 0.4% behind the AMD Ryzen 9 9900X3D (54681). It trails the Intel Core Ultra 5 245K by 1.5% and the 245KF by 1.8%.

Q: What is the biggest bottleneck in this system for Doom?

A: The Radeon RX 580 is the clear limiting factor. Evidence from resolution scaling shows frame rates dropping dramatically as resolution increases, while the CPU's 12 cores and 24 threads remain largely underutilized in a game that is not heavily multi-threaded.

Q: Can this system handle 4K gaming in Doom?

A: No. At 3840x2160, the best average FPS recorded is 37.6 on Low settings. High settings yield 29.1 FPS, Medium 30.6 FPS, and Ultra drops to 24.4 FPS. None of these are playable for a competitive FPS.

Q: How does the RX 580's performance compare to other GPUs in its class?

A: The RX 580's average benchmark score of 13559 is statistically identical to the GTX 570 (13564) and GTX 950 (13549), with deltaPct values of 0 and 0.1 respectively. It sits 1.1% above the AMD Radeon Pro 455 and 1.1% below the NVIDIA P106-090.

Q: Is the CPU's high core count beneficial for Doom specifically?

A: Not particularly. Doom was released in 2016 and does not scale heavily across 12 cores. The Ryzen 9 9900X's single-thread performance (PassMark score of 4672) is more relevant, but even that advantage is wasted when the GPU cannot keep up.

Resolution Scaling

The performance drop from 1080p to 4K is stark and reveals exactly where the bottleneck lies. At 1080p High settings, the combo delivers 74.3 FPS; at 1440p High, that falls to 52 FPS; and at 4K High, it plummets to 29.1 FPS. This represents a 30% reduction from 1080p to 1440p, and a further 44% reduction from 1440p to 4K. The pattern is consistent across all settings presets, indicating a GPU-bound scenario where the RX 580's 256-bit memory bus and 256.0 GB/s bandwidth simply cannot feed the pixel pipeline fast enough at higher resolutions.

The data shows that the CPU is not the constraint. The Ryzen 9 9900X, with a boost clock of 5.60 GHz and a PassMark single-thread score of 4672, is more than capable of driving Doom's game logic at any resolution. The frame rate drops are purely a function of the GPU's rendering load. At 1080p Low, the system hits 103.3 FPS, which approaches the practical ceiling for a game of this era, but even at that resolution, the RX 580 is working near its maximum output.

The scaling behavior also shows that the RX 580's 8 GB of GDDR5 memory is not the primary issue—the card's compute throughput (6.175 TFLOPS FP32) and texture fill rate (193.0 GTexel/s) are the limiting factors. At 4K, the GPU is rendering four times the pixels of 1080p, and the architecture simply does not have the raw power to maintain playable frame rates. This is a classic case where resolution scaling exposes the GPU as the definitive bottleneck, regardless of the CPU's capabilities.

Measured FPS Breakdown

At 1920x1080, the system delivers its best results. Low settings produce an average of 103.3 FPS, which is smooth and responsive for a fast-paced shooter. Medium settings yield 87.5 FPS, High settings drop to 74.3 FPS, and Ultra settings bottom out at 60.6 FPS. The gap between Low and Ultra is 42.7 FPS, showing that the RX 580 has a limited range of performance when pushed by higher quality presets.

Moving to 2560x1440, the frame rates become more marginal. Low settings manage 65.7 FPS, which is still playable, but Medium drops to 58.9 FPS and High to 52 FPS. Ultra settings fall to 38.1 FPS, which is below the threshold for comfortable gameplay in a shooter. The drop from 1080p Ultra to 1440p Ultra is 22.5 FPS, a 37% reduction that highlights the GPU's inability to handle higher pixel counts with maxed-out effects.

At 3840x2160, the results are largely unplayable. Low settings average 37.6 FPS, Medium 30.6 FPS, High 29.1 FPS, and Ultra just 24.4 FPS. The difference between Low and Ultra at 4K is only 13.2 FPS, indicating that the GPU is so overwhelmed that settings changes have a diminishing impact. The data shows a consistent pattern: the RX 580 is a 1080p-class card, and its performance degrades predictably and severely as resolution increases, with no settings preset able to rescue 4K performance.

Settings Recommendations

For the best balance of visual quality and playable frame rates, the Medium preset at 1080p is the strongest recommendation. The 87.5 FPS average provides a comfortable margin above the 60 FPS threshold, and Medium settings in Doom still include dynamic lighting and particle effects that make the game look good. High settings at 1080p are also viable at 74.3 FPS, offering improved texture detail and shadow quality for those who prefer visuals over raw speed.

At 1440p, Low settings are the only fully playable option at 65.7 FPS. Medium at 58.9 FPS is borderline—playable for casual sessions but risky for competitive play where consistent frame times matter. High settings at 52 FPS are acceptable for slower-paced exploration but not ideal for combat-heavy sequences. Ultra settings should be avoided at 1440p; the 38.1 FPS average will feel stuttery and unresponsive.

At 4K, no settings preset is recommended. Even Low settings at 37.6 FPS will result in noticeable input lag and screen tearing. Users who own a 4K monitor should either lower the display resolution to 1440p or accept that this combination is not suitable for high-resolution gaming. The Ultra preset at 1080p, while hitting 60.6 FPS, is not recommended over High because the extra visual fidelity is minimal while the frame rate margin shrinks significantly. The data clearly favors Medium at 1080p as the sweet spot for this hardware pairing.

CPU Role

The AMD Ryzen 9 9900X is a 12-core, 24-thread processor based on the Zen 5 architecture, built on a 4 nm process at TSMC. It has a base clock of 4.40 GHz and a boost clock of 5.60 GHz, with 64 MB of shared L3 cache and 1 MB of L2 cache per core. Its benchmark scores are formidable: a Cinebench R23 multi-core score of 46438 and a single-core score of 6555, with a PassMark multi-thread score of 54643 and a single-thread score of 4672.

In the context of Doom, however, this CPU's immense multi-threaded capability is largely irrelevant. Doom, released in 2016, was designed to run on quad-core processors of that era. The game's Vulkan renderer can utilize multiple threads, but it does not scale to 12 cores or 24 threads. The CPU's single-thread performance is what matters most, and the 9900X excels there, ranking in the 94th percentile of all CPUs. The data shows that at 1080p Low settings, the system achieves 103.3 FPS, which is likely near the game's engine limit or the GPU's maximum output—the CPU is not holding back performance.

The processor's 120W TDP and support for DDR5 memory with 89.6 GB/s bandwidth are modern advantages, but they do not translate to higher frame rates in this title. The nearest rivals comparison shows the 9900X is essentially tied with the Ryzen 9 9900X3D (deltaPct -0.4) and slightly ahead of the Intel Core i7-14700F (deltaPct 0.7), confirming that the CPU is not a weak link. In this pairing, the CPU is like a high-performance engine connected to a restricted exhaust—it has far more capability than the GPU can utilize.

GPU Role

The AMD Radeon RX 580 is the defining component in this system's Doom performance, and the data shows it is a severe bottleneck. This GPU, based on the Polaris 20 chip with GCN 4.0 architecture, has 2304 shading units, 144 texture mapping units, and 32 ROPs. It operates at a base clock of 1257 MHz and a boost clock of 1340 MHz, with 8 GB of GDDR5 memory on a 256-bit bus providing 256.0 GB/s of bandwidth. Its compute capability is rated at 6.175 TFLOPS FP32, with a texture fill rate of 193.0 GTexel/s and a pixel rate of 42.88 GPixel/s.

The GPU's benchmark performance is modest: a PassMark G3D score of 8813 and a 3DMark Steel Nomad DX12 score of 1005. Its percentile rank of 53 places it in the middle of the pack, and its nearest rivals are all older or lower-tier cards. The GTX 570 and GTX 950 match its performance within 0.1%, confirming that this is not a high-end part by any modern standard. The RX 580's 14 nm process and 185W TDP are dated, and its DirectX 12 support is limited to feature level 12_0, which may restrict some modern rendering features.

In Doom, the GPU's limitations are exposed immediately. The frame rates at 4K are unplayable, and even at 1440p, the card struggles to maintain 60 FPS on any preset. The 1080p results are the only saving grace, with Low settings hitting 103.3 FPS. The GPU's 8 GB of VRAM is sufficient for this game at 1080p and 1440p, but its raw compute power and memory bandwidth are insufficient for higher resolutions. The data indicates that the RX 580 is fundamentally a 1080p gaming card, and its pairing with a top-tier 2024 CPU does not change that reality—the GPU remains the hard limit on performance.
