Doom

The AMD Ryzen 7 9850X3D paired with the AMD Radeon RX 580 produces a very specific performance profile in Doom, one that is heavily dictated by the graphics card’s legacy architecture. The measured frame rates across the three resolutions and four settings presets show a clear pattern: the RX 580 is the limiting factor in almost every scenario, while the CPU’s immense headroom remains largely untapped. This analysis walks through the data step by step, starting with how the game scales with resolution.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent, which is the classic signature of a GPU-bound workload. At High settings, the average frame rate falls from 75 FPS at 1920x1080 to 49 FPS at 2560x1440, a reduction of 26 FPS. Moving to 3840x2160, the average drops further to 26 FPS, which is roughly one-third of the 1080p score. This linear decline with pixel count is typical for a graphics card that is working at its absolute limit; the RX 580’s 6.175 TFLOPS of FP32 performance and 256.0 GB/s of memory bandwidth are simply overwhelmed by the 4K pixel pipeline.

The scaling pattern at Low settings reinforces this conclusion. At 1080p Low, the combo achieves 102 FPS, which drops to 66 FPS at 1440p and then to 36 FPS at 4K. The percentage drop from 1080p to 4K is roughly 65%, which is almost identical to the drop seen at High settings (65% as well). When lowering the preset from High to Low, the performance gain at 4K is only 10 FPS (from 26 to 36), while at 1080p the gain is 27 FPS (from 75 to 102). This indicates that at 4K, the GPU is so constrained by raw fill rate and memory throughput that reducing shading complexity yields diminishing returns. The limiting component is unequivocally the GPU; the Ryzen 7 9850X3D’s 5.60 GHz boost clock and 96 MB of L3 cache have no bearing on these resolution-based cliffs.

The data also shows that the gap between Medium and Ultra settings widens as resolution increases. At 1080p, the difference between Medium (89 FPS) and Ultra (62 FPS) is 27 FPS. At 1440p, the gap between Medium (58 FPS) and Ultra (40 FPS) is 18 FPS. At 4K, the gap narrows to 9 FPS (31 FPS versus 22 FPS). This compression of the settings range at higher resolutions is a direct consequence of the GPU becoming the bottleneck; the rendering pipeline is saturated, so the cost of each additional visual effect becomes relatively more expensive in terms of frame time, but the absolute FPS penalty is smaller because the baseline is so low.

How This Combo Ranks

In the grand scheme of all tested combinations for Doom, this pairing sits near the bottom. The combo rank is 2675 out of 2930 combos, placing it in the 8th percentile of all systems tested in this game. This is a low ranking, but it is not surprising given the hardware mix. The RX 580’s own percentile rank against all GPUs is 53, meaning it is an average graphics card by modern standards, but its architectural age is a severe handicap for a fast-paced FPS like Doom.

The CPU, in contrast, is a top-tier part. The Ryzen 7 9850X3D has a percentile rank of 92 against all CPUs, and its average benchmark score of 58386 places it directly between the Intel Xeon Platinum 8260M (58323, a 0.1% delta) and the Intel Xeon w5-2545 (58504, a -0.2% delta). This indicates that the processor is not the source of the low combo ranking. Instead, the bottleneck is the GPU. The RX 580’s average benchmark score of 12928 places it just 0.1% below the NVIDIA GeForce RTX 3050 Ti Mobile and 0.4% below the NVIDIA GeForce GTX 1660 SUPER. These rival GPUs are all in the same performance class, and none of them are designed for high-refresh 1440p or 4K gaming in modern titles.

The rank of 2675 out of 2930 suggests that the overwhelming majority of other combos include either a more modern GPU or a more balanced CPU-GPU pairing. In Doom, which is known for its demanding Vulkan rendering, the combination of a 2026-era CPU with a 2017-era GPU creates a massive performance asymmetry. The data shows that the combo’s position is dictated entirely by the GPU’s limits, and no amount of CPU headroom can compensate for the RX 580’s raw pixel throughput.

FAQ

Q: Why does the combo perform so poorly at 4K even on Low settings?

A: The RX 580’s memory bandwidth of 256.0 GB/s and its 32 ROPs are insufficient for the pixel workload at 3840x2160. The data shows only 36 FPS on Low and 26 FPS on High, indicating that even minimal shading loads cannot overcome the fixed-function throughput limits at this resolution.

Q: Is the Ryzen 7 9850X3D holding back the RX 580 in this game?

A: No. The CPU’s benchmark scores are extremely high, with a Cinebench R23 multi-core score of 22807 and a single-core score of 2228. The measured FPS scaling from 1080p to 4K shows a classic GPU-bound curve, meaning the processor is not the limiting factor.

Q: What is the best resolution to play this game with this hardware?

A: The data supports 1920x1080 as the only resolution where the combo achieves consistently playable frame rates. At Medium settings, the average is 89 FPS, and at High settings, it is 75 FPS. At 2560x1440, even Low settings only produce 66 FPS, which is below the threshold for smooth gameplay on many high-refresh monitors.

Q: How does the RX 580 compare to its closest rivals in this system?

A: The RX 580’s average benchmark score of 12928 is 0.1% lower than the NVIDIA GeForce RTX 3050 Ti Mobile (12940) and 0.4% lower than the NVIDIA GeForce GTX 1660 SUPER (12986). These are all statistically equivalent in raw compute, so the performance in Doom would be expected to be very similar.

Q: Does the CPU’s 3D V-Cache technology have any impact on Doom’s frame rates?

A: The CPU has a 96 MB shared L3 cache and a high boost clock of 5.60 GHz, but the measured FPS data shows that the game is not CPU-bound at any resolution. The frame rates are entirely determined by the GPU’s performance, so the cache advantage does not translate into higher FPS in this specific configuration.

Q: What is the expected performance difference between Ultra and Low settings at 1080p?

A: The measured data shows a 40 FPS gap: 102 FPS on Low versus 62 FPS on Ultra. This is a 39% reduction in frame rate when moving to the highest preset, which is a significant cost for the visual fidelity gains.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. The Low preset achieves an average of 102 FPS, which is the highest recorded score in the entire dataset. The Medium preset follows with 89 FPS, with a minimum of 76 FPS and a maximum of 103 FPS. The High preset drops to 75 FPS, and the Ultra preset bottoms out at 62 FPS. The spread from Low to Ultra is 40 FPS, which shows that the RX 580 has enough headroom at this resolution to render the game’s effects but not enough to maintain high frame rates on the highest settings.

Moving to 2560x1440, the performance drops significantly. Low settings produce 66 FPS, which is still playable but noticeably lower than the 1080p result. Medium settings yield 58 FPS, with a minimum of 49 FPS and a maximum of 66 FPS. High settings fall to 49 FPS, and Ultra settings drop to 40 FPS. The gap between Low and Ultra is 26 FPS, which is smaller than at 1080p. This indicates that the GPU is starting to hit its memory bandwidth limits, as the 256-bit bus cannot feed the shaders fast enough to maintain the higher settings’ demands.

At 3840x2160, the results are mostly unplayable for a fast-paced FPS. Low settings average 36 FPS, Medium settings average 31 FPS (with a minimum of 27 FPS and a maximum of 36 FPS), High settings average 26 FPS, and Ultra settings average 22 FPS. The minimum frame rate at Medium (27 FPS) suggests that there are significant frame-time spikes, which would cause stuttering during intense combat scenes. The difference between Low and Ultra is only 14 FPS, confirming that the GPU is completely saturated at this resolution.

The data also reveals a consistent pattern in the minimum FPS values. Only the Medium presets at 1080p (76 FPS), 1440p (49 FPS), and 4K (27 FPS) have recorded minimums. This suggests that Medium settings produce the most stable frame pacing, as the minimums are closer to the averages. The lack of minimum data for other presets implies that the frame time variance is higher, but without those numbers, the average is the only reliable metric for comparison.

Settings Recommendations

Based on the measured rows, the optimal experience for this hardware is at 1920x1080 with the Medium preset. This configuration achieves 89 FPS average, which is high enough for smooth gameplay, and the recorded minimum of 76 FPS ensures that there are no severe drops below the refresh rate of a standard 60 Hz monitor. The Medium preset also provides a balanced visual experience, as the Low preset’s 102 FPS is only 13 FPS higher but likely sacrifices significant visual quality.

At 2560x1440, the Low preset is the only viable option, producing 66 FPS. However, this is below the 70 FPS threshold that many players consider the minimum for a responsive shooter. The Medium preset at 1440p (58 FPS) is borderline, and the data shows that the High and Ultra presets (49 and 40 FPS respectively) are not recommended for competitive play.

At 3840x2160, none of the presets deliver a playable experience. The Low preset’s 36 FPS is technically above the 30 FPS cinematic standard, but it is not suitable for a game that requires quick reactions. The Ultra preset’s 22 FPS is a slideshow. Therefore, the recommendation is to avoid 4K entirely with this GPU and instead prioritize frame rate over resolution.

The data suggests that the Medium preset is the sweet spot for this combo. The minimum FPS values are only available for Medium settings, which is a strong indicator of frame time consistency. The gap between Medium and High at 1080p is 14 FPS (89 versus 75), which is a 16% reduction in performance for incremental visual gains. The Medium preset offers the best balance between the GPU’s capabilities and the game’s demands.

CPU Role

The AMD Ryzen 7 9850X3D is a flagship desktop processor based on the Zen 5 architecture on a 4 nm process. It features 8 cores and 16 threads, with a base clock of 4.70 GHz and a boost clock of 5.60 GHz. The CPU has a 96 MB shared L3 cache, which is a significant amount for game data. Its benchmark results are substantial: a Cinebench R23 multi-core score of 22807 and a single-core score of 2228, alongside a Passmark multi-thread score of 41318.

In Doom, the CPU’s role is to feed the GPU with draw calls and game logic. The measured FPS data shows that the CPU is not the bottleneck in any of the tested configurations. The fact that the frame rate drops by roughly 65% when moving from 1080p to 4K at both Low and High settings is definitive proof that the GPU is the limiting factor. If the CPU were the bottleneck, the frame rates would remain relatively flat across resolutions.

The CPU’s high single-thread performance (Passmark single-thread score of 4704) is more than adequate for Doom’s engine, which is well-optimized for multi-core processors. The 16 threads provide ample parallelism for the game’s physics and AI systems. However, the data shows that the combo’s rank of 2675 out of 2930 is not due to the CPU. The processor’s nearest rivals, such as the Intel Core i9-14900 (average score 58115, a 0.5% delta), are all similarly powerful, and none of them would change the outcome with an RX 580.

The CPU’s memory support for DDR5 at 89.6 GB/s bandwidth is also unlikely to affect Doom’s performance, as the game is not memory-bandwidth sensitive at the GPU-bound settings tested. The L3 cache of 96 MB is a notable feature, but it cannot compensate for the GPU’s 256-bit memory bus limitations. In short, the Ryzen 7 9850X3D is overqualified for this pairing, and its performance headroom is entirely wasted in this specific game and resolution range.

GPU Role

The AMD Radeon RX 580 is the primary determinant of this combo’s performance. This GPU is based on the Polaris 20 chip, built on a 14 nm process with GCN 4.0 architecture. It has 2304 shading units, 144 texture mapping units, and 32 ROPs. The core clock runs at 1257 MHz base and 1340 MHz boost, with a memory clock of 2000 MHz (8 Gbps effective) across a 256-bit bus, yielding 256.0 GB/s of bandwidth. The GPU’s FP32 performance is 6.175 TFLOPS.

The measured FPS data directly reflects these specifications. The 32 ROPs are the primary bottleneck at high resolutions, as they determine the pixel fill rate. The pixel rate is 42.88 GPixel/s, which is simply insufficient for 3840x2160 at high settings. The GPU’s texture rate of 193.0 GTexel/s is more robust, but it cannot compensate for the ROP limitation.

The RX 580’s benchmark scores place it in the 53rd percentile of all GPUs, with an average score of 12928. Its nearest rivals are the NVIDIA GeForce GTX 1660 SUPER (12986, a -0.4% delta) and the NVIDIA GeForce RTX 3050 Ti Mobile (12940, a -0.1% delta). These are all mid-range GPUs from their respective generations, and they all struggle with modern titles at high resolutions.

The GPU’s 8 GB of GDDR5 memory is sufficient for Doom’s texture requirements, as the game was released in 2016 and does not have the massive VRAM demands of newer titles. However, the memory bandwidth of 256.0 GB/s is the limiting factor at 1440p and 4K. The data shows that the frame rate drops are proportional to the increase in pixel count, which is a clear sign of bandwidth saturation. The GPU’s TDP of 185 W and its 8-pin power connector are historical details, but they do not influence the measured performance. In summary, the RX 580 is a legacy GPU that cannot deliver playable frame rates at 1440p or 4K in this game, and its age is the sole reason for the combo’s low ranking.
