Doom

The pairing of the AMD Ryzen 9 7900X with the AMD Radeon RX 570 in Doom yields a performance profile that is almost entirely dictated by the graphics card. The data shows a system that is capable of producing playable frame rates at lower resolutions and settings, but which quickly becomes constrained as graphical demands increase. This analysis breaks down the measured results, placing them in context with the component's specifications and relative performance rankings.

Settings Recommendations

For this specific configuration, the choice of graphics preset is the single most critical factor in achieving a smooth experience. The measured data indicates that at 1080p, the Low preset delivers an average of 90.9 FPS, which is the highest frame rate recorded for any setting at any resolution. This provides a substantial performance headroom and is the only setting that approaches the range of high-refresh-rate monitors. The Medium preset at 1080p, with an average of 82.7 FPS, is also a very strong candidate, offering a significant visual upgrade over Low for a relatively modest performance cost of approximately 8 FPS. This appears to be the optimal balance for competitive or fast-paced play.

At 1440p, the situation becomes more demanding. The Low preset is the only one that breaks the 60 FPS barrier, achieving an average of 60.2 FPS. This makes it the only viable option at this resolution for users who prioritize a consistently smooth frame rate. The Medium preset at 1440p drops to 51.6 FPS, while High falls to 44 FPS. At 4K, no preset achieves a playable frame rate. The Low setting tops out at 32.5 FPS, and the Ultra setting drops to a marginal 21.6 FPS. The data strongly suggests that 4K gaming is not a realistic option for this hardware combination. The best experience for this combo is unequivocally at 1080p, with the Medium preset offering the strongest blend of visual fidelity and smooth, responsive gameplay.

GPU Role

The AMD Radeon RX 570 is the primary performance limiter in this system. Its specifications, including 4 GB of GDDR5 memory on a 256-bit bus providing 224.0 GB/s of bandwidth, and a boost clock of 1244 MHz, are from a previous generation. The data shows a clear pattern: as the resolution and settings increase, the average frame rate drops sharply. This is the classic signature of a GPU-bound scenario. The 4 GB VRAM capacity is also a likely point of strain at higher settings, potentially causing texture thrashing and contributing to the steep performance declines observed at 4K.

The GPU's benchmark scores confirm its mid-range standing. It holds a percentile rank of 74 among all GPUs and its average benchmark score is 30158. Interestingly, its nearest rivals in benchmark score are the NVIDIA GeForce RTX 5060 and AMD Radeon RX 7700 XT, with deltaPct values of 0.2%. This suggests that while its aggregate benchmark score is in a similar range to these modern cards, its real-world gaming performance in this specific title, as measured here, is far below what those newer architectures would achieve, underscoring how older hardware can struggle with newer games' demands.

How This Combo Ranks

In the grand scheme of tested combinations, this pairing of the Ryzen 9 7900X and RX 570 finds itself near the bottom. The data places this combo at a rank of 1616 out of 1681 tested combos for Doom. This places it in the bottom 4% of all possible pairings, a stark illustration of the performance bottleneck created by the GPU. The incredibly powerful CPU is being held back by a graphics card that is simply not in the same performance class for this game.

This low rank is not a reflection of any single component's failure but rather a severe mismatch. The CPU has the potential to drive frame rates far higher than what is being recorded. The fact that the combo ranks so low indicates that the RX 570 is unable to keep up with the CPU's ability to prepare frames, leaving the processor idling for much of the time. The data shows a system whose potential is heavily gated by its oldest and weakest part.

FAQ

Q: Can this system run Doom at 4K resolution?

A: No. The measured data shows that even at the lowest settings, the average frame rate at 3840x2160 is only 32.5 FPS. At the highest "Ultra" setting, it drops to 21.6 FPS, which is far below a playable threshold.

Q: What is the best resolution for this CPU and GPU combination?

A: The data strongly indicates that 1920x1080 is the only resolution that provides a consistently good experience. At 1080p, the average frame rates range from 53.8 FPS on Ultra to 90.9 FPS on Low. In contrast, at 2560x1440, only the Low preset manages to stay above 60 FPS.

Q: How does the "High" preset compare to "Medium" at 1080p?

A: The performance cost of moving from Medium to High at 1080p is significant. The average frame rate drops from 82.7 FPS on Medium to 65.6 FPS on High. This 17 FPS reduction is a substantial price to pay for the visual upgrade, making Medium the more sensible choice for smoother gameplay.

Q: Is the AMD Ryzen 9 7900X the reason for the low performance in Doom?

A: No. The data indicates the opposite. The Ryzen 9 7900X is a high-end processor with a strong average benchmark score of 50556. The performance bottleneck is clearly the AMD Radeon RX 570, as evidenced by the dramatic frame rate drops that occur when resolution and graphical settings are increased.

Q: What is the performance difference between the "Low" and "Ultra" presets at 1440p?

A: The difference is very large. The Low preset achieves an average of 60.2 FPS, which is playable. The Ultra preset, however, only manages an average of 38.4 FPS. This represents a 21.8 FPS drop for the highest visual quality, which is too costly for this hardware to maintain a smooth frame rate.

Q: According to benchmark scores, which GPUs are the RX 570's closest rivals?

A: The data lists the NVIDIA GeForce RTX 5060 and the AMD Radeon RX 7700 XT as having nearly identical average benchmark scores, with a deltaPct of 0.2%. This reflects how benchmark scores can sometimes mask large differences in real-world gaming performance.

Resolution Scaling

The measured frame rates reveal a steep and consistent decline as resolution scales from 1080p to 4K. At the "High" setting, the average FPS drops from 65.6 at 1080p to 44 at 1440p, a 33% reduction, and then plummets to 23 at 4K, a 65% reduction from the 1080p baseline. This pattern is repeated across all settings. For instance, on "Low," the frame rate goes from 90.9 at 1080p to 60.2 at 1440p, and finally to 32.5 at 4K.

This consistent and severe scaling pattern is a definitive indicator of a GPU-bound system. The CPU, which has ample headroom, is not the limiting factor; if it were, the frame rates would be more similar across resolutions. The data shows that the RX 570's pixel processing capabilities are being overwhelmed as the number of pixels increases. The jump from 1440p to 4K is particularly punishing, with frame rates nearly halving in most cases. This makes it clear that the graphics card is the sole arbiter of performance, and its limits are quickly reached as resolution demands increase.

CPU Role

The AMD Ryzen 9 7900X is a top-tier processor with 12 cores and 24 threads, based on the Zen 4 architecture. Its base clock is 4.70 GHz and it can boost up to 5.60 GHz. In synthetic benchmarks, it performs exceptionally well, with a Cinebench R23 multicore score of 43695 and a single-core score of 6168. Its average benchmark score of 50556 places it in the 93rd percentile of all CPUs. The data in this game, however, suggests that its immense processing power is largely untapped.

Given the low frame rates, especially at higher resolutions, it's clear the game is not CPU-limited. The Ryzen 9 7900X is capable of feeding the RX 570 far more frames than the GPU can render. The measured FPS at 1080p Low (90.9 FPS) is likely a direct reflection of the GPU's maximum output, not the CPU's. The CPU is so powerful that it is effectively waiting for the GPU to catch up, a scenario that leaves the 12-core, 24-thread processor severely underutilized in this particular pairing.

Measured FPS Breakdown

The following data is the complete set of measured average frame rates for this configuration.

3840x2160 (4K)

• Ultra: 21.6 FPS
• High: 23 FPS
• Medium: 28.5 FPS
• Low: 32.5 FPS

2560x1440 (1440p)

• Ultra: 38.4 FPS
• High: 44 FPS
• Medium: 51.6 FPS
• Low: 60.2 FPS

1920x1080 (1080p)

• Ultra: 53.8 FPS
• High: 65.6 FPS
• Medium: 82.7 FPS
• Low: 90.9 FPS

The data reveals a clear hierarchy. The 1080p Low setting is the performance peak, while 4K Ultra is the performance floor. The gap between the best and worst measured settings is 69.3 FPS. The scaling across settings is mostly linear, but the differences become more pronounced at lower resolutions, where the GPU has more relative headroom to be the limiting factor. At 4K, even the difference between Low and Ultra is a relatively small 10.9 FPS, showing that the GPU is completely saturated at that resolution regardless of quality settings.
