Doom

The AMD Ryzen 7 9850X3D paired with the AMD Radeon RX 570 presents a significant bottleneck scenario in Doom, where the GPU’s age and 4 GB VRAM capacity severely limit performance regardless of the CPU’s capabilities. The measured data indicates this combination is firmly positioned at the lower end of the performance spectrum, with the combo ranking 2812 out of 2930 tested configurations. This analysis focuses purely on the observed frame rates and hardware characteristics to guide settings and expectations.

Settings Recommendations

Based on the measured FPS data, the optimal experience for this combo is achieved at 1920x1080 with Low settings, which delivers an average of 92 FPS. This is the only settings level that provides a consistently smooth, high-refresh experience suitable for a fast-paced FPS like Doom. Dropping to Medium at this resolution still yields a respectable 80 FPS average, but the 68 FPS minimum observed suggests potential dips that could be noticeable during intense combat sequences. For players prioritizing visual fidelity over absolute smoothness, High at 1080p offers 68 FPS average, which is playable but leaves little headroom.

At 2560x1440, the situation becomes more constrained. The Low preset is the only viable option, hitting exactly 60 FPS average. This is the bare minimum for acceptable playability, and any increase in settings will push frame rates below that threshold. Medium at 1440p drops to 52 FPS average with a 44 FPS minimum, which will feel sluggish in a game requiring rapid reactions. The High and Ultra presets at this resolution are not recommended, as they deliver 44 and 36 FPS averages respectively.

At 4K (3840x2160), this combination is simply not viable for playable frame rates. Even the Low preset only manages a 32 FPS average, which is well below the threshold for an enjoyable FPS experience. The Ultra preset at 4K produces an unplayable 19 FPS average. The data clearly indicates that this resolution should be avoided entirely with this hardware pairing.

The most balanced recommendation is 1080p with Medium settings. While it drops 12 FPS compared to Low, it likely provides improved visual quality without sacrificing the core gameplay experience. The 80 FPS average is still well within playable territory, and the 68 FPS minimum indicates that the experience remains fluid even in demanding scenes. For those who prioritize maximum performance, Low at 1080p is the safest choice.

GPU Role

The AMD Radeon RX 570 is the primary limiting factor in this configuration. Its 4 GB of GDDR5 memory on a 256-bit bus provides 224.0 GB/s of bandwidth. In a game like Doom, which can be texture-heavy, this VRAM capacity is a critical constraint. The data shows that at 1440p and 4K, even the Low preset struggles to maintain playable frame rates, strongly suggesting that the GPU is running out of memory and resorting to slower fallback mechanisms.

The GPU’s base clock of 1168 MHz and boost clock of 1244 MHz are modest by modern standards. The Polaris 20 chip, built on a 14 nm process, delivers 5.095 TFLOPS of FP32 performance. This compute capability is sufficient for 1080p gaming but is overwhelmed by the pixel throughput demands of higher resolutions. The pixel rate of 39.81 GPixel/s and texture rate of 159.2 GTexel/s explain why performance degrades so sharply as resolution increases.

The RX 570’s benchmark scores place it in the 74th percentile of all GPUs. Its nearest rival, the AMD Radeon RX 6800M, has an average score only 0.4% higher, while the AMD Radeon RX 470 sits 0.8% lower. This shows that the RX 570 is performing as expected for its class. However, this performance class is simply insufficient for the demands of Doom at higher resolutions with this particular CPU pairing.

The GPU’s 2048 shading units and 32 ROPs are the hardware elements that directly impact frame rendering. The measured FPS data shows a clear pattern: at 1080p, the GPU can keep up with the CPU’s frame generation, but at 1440p and 4K, the rendering pipeline becomes the bottleneck. The 150 W TDP and 1x 6-pin power connector indicate this is a power-efficient card, but efficiency does not translate to high-end performance.

FAQ

Q: What is the best resolution for this CPU and GPU combo in Doom?

A: The data shows 1920x1080 is the only resolution where playable frame rates are consistently achieved. At 1080p, all settings presets deliver at least 56 FPS average, while at 1440p only the Low preset reaches 60 FPS, and at 4K even Low settings only produce 32 FPS.

Q: Is the Ryzen 7 9850X3D holding back the RX 570 in this game?

A: No, the opposite is true. The CPU’s benchmark scores are far superior to the GPU’s. The Ryzen 7 9850X3D achieves a 92nd percentile ranking among all CPUs, while the RX 570 is in the 74th percentile for GPUs. The frame rates are clearly limited by the GPU’s rendering capabilities, not the CPU’s processing power.

Q: Can this combo handle 1440p gaming in Doom?

A: Only at the lowest settings preset. The measured data shows 60 FPS average at 1440p with Low settings. Any higher preset drops below 52 FPS average, which is not ideal for a fast-paced FPS. Medium settings at 1440p produce 52 FPS average with a 44 FPS minimum.

Q: How does the RX 570 compare to its direct predecessor, the RX 470?

A: The RX 570 has an average benchmark score of 28766, which is 0.8% higher than the RX 470’s score of 28996. This indicates a very small performance improvement, confirming that the RX 570 is essentially a refined version of the same architecture.

Q: What frame rate can I expect at 1080p with Ultra settings?

A: The measured average is 56 FPS. While this is playable, it is the lowest average among the 1080p presets. The High preset offers 68 FPS, Medium offers 80 FPS, and Low offers 92 FPS, showing a clear trade-off between visual quality and frame rate.

Q: Is the 4 GB VRAM sufficient for Doom?

A: The data suggests it is insufficient for higher resolutions. At 4K, all presets fail to reach 32 FPS average, and at 1440p, only the Low preset achieves 60 FPS. This pattern indicates that memory capacity, combined with the GPU’s compute limits, prevents smooth performance at resolutions above 1080p.

How This Combo Ranks

This combination ranks 2812 out of 2930 tested combos in Doom, placing it in the bottom 4% of all configurations. This very low ranking is a direct result of the massive performance disparity between the CPU and GPU. The Ryzen 7 9850X3D is a high-end processor, but it is paired with a GPU whose average benchmark score is only 28766, placing it in the 74th percentile of all GPUs.

The ranking indicates that this is not a balanced system for Doom. The data shows that frame rates are consistently limited by the GPU across all resolutions and settings. At 1080p, the combo achieves competitive frame rates, but this is due to the low resolution reducing the GPU’s workload rather than the CPU’s strength. The high CPU performance does not translate into higher FPS because the GPU cannot render frames fast enough to utilize the CPU’s processing capacity.

Comparing the GPU to its nearest rivals further contextualizes this ranking. The RX 570’s score is only 0.4% lower than the RX 6800M and 0.7% higher than the R9 M295X. This shows that the GPU is performing at an expected level for its hardware class. The low combo ranking is therefore not a result of a defective or underperforming GPU, but rather a fundamental mismatch between the CPU’s high-end capabilities and the GPU’s entry-level to mid-range performance.

CPU Role

The AMD Ryzen 7 9850X3D is a high-end desktop processor with 8 cores and 16 threads, based on the Zen 5 architecture on a 4 nm process. Its base clock of 4.70 GHz and boost clock of 5.60 GHz are exceptionally high, and the 96 MB of shared L3 cache is a significant asset for gaming workloads. The CPU’s benchmark scores are impressive, with a Cinebench R23 multi-core score of 22807 and a single-core score of 2228.

However, in this specific configuration, the CPU’s role in Doom is largely secondary. The measured FPS data shows that performance is almost entirely GPU-bound. At 1080p Low settings, the combo achieves 92 FPS, but at 1080p Ultra, this drops to 56 FPS. This 36 FPS difference is entirely due to the GPU’s workload increasing with higher settings, not the CPU’s limitations.

The CPU’s performance percentile of 92 indicates it is far more capable than the GPU. Its nearest rivals include the Intel Core i9-14900, which has a score only 0.5% lower, and the AMD Ryzen AI 9 HX 470, which is 0.7% higher. This places the CPU in the top tier of processors. In a game like Doom, which is not particularly CPU-intensive, this processor provides more than enough processing power to feed the GPU with draw calls and game logic.

The CPU’s memory bandwidth of 89.6 GB/s and DDR5 support ensure that data can be fed to the GPU without bottlenecks. The PCIe Gen 5 interface with 24 lanes provides ample bandwidth for the GPU, even though the RX 570 only uses PCIe 3.0 x16. The CPU’s capabilities are effectively wasted in this pairing, as the GPU becomes the limiting factor well before the CPU’s resources are fully utilized.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best performance. The Low preset achieves 92 FPS average, the highest of any configuration tested. The Medium preset drops to 80 FPS average, with a minimum of 68 FPS and a maximum of 93 FPS. The High preset produces 68 FPS average, while the Ultra preset bottoms out at 56 FPS average. This shows a clear linear progression where each step up in settings costs approximately 12 FPS.

At 2560x1440, performance falls significantly. The Low preset is the only one to reach 60 FPS average, which is the exact threshold for smooth playability. The Medium preset averages 52 FPS, with a minimum of 44 FPS and a maximum of 60 FPS. The High preset drops to 44 FPS average, and the Ultra preset averages only 36 FPS. The gap between Low and Ultra at this resolution is 24 FPS, indicating that the GPU struggles with the increased pixel count.

At 3840x2160, the combo is not viable for gameplay. The Low preset averages 32 FPS, which is below playable thresholds. The Medium preset averages 28 FPS, with a minimum of 24 FPS and a maximum of 32 FPS. The High preset drops to 24 FPS average, and the Ultra preset averages only 19 FPS. The data shows a steep decline from 1440p to 4K, with the GPU’s rendering capabilities being overwhelmed by the 4K pixel count.

The pattern across all resolutions is consistent: the GPU is the limiting factor. At 1080p, the RX 570 can maintain reasonable frame rates because the pixel load is manageable. At 1440p, only the lowest settings are playable. At 4K, no settings preset achieves playable performance. This breakdown confirms that the Ryzen 7 9850X3D’s processing power is not the bottleneck; rather, the RX 570’s 4 GB VRAM and 5.095 TFLOPS compute capability define the performance ceiling for this combo.
