Doom

The AMD Ryzen 7 9800X3D paired with the AMD Radeon RX 570 presents a striking contrast in capabilities within the 2016 FPS Doom. The CPU is a high-end, current-generation part with a strong benchmark pedigree, while the GPU is an end-of-life Polaris architecture card from 2017. The measured frame rates in this analysis reflect that imbalance, showing that the graphics card is the definitive limiting factor across all tested resolutions and settings. The data quantifies exactly how this bottleneck scales, offering a clear picture of what this combination can and cannot deliver.

Resolution Scaling

The performance drop from 1080p to 4K is steep and consistent, confirming that the RX 570 is the primary constraint. At 1080p High, the combo produces 71.1 FPS. Moving to 1440p High, the average falls to 45.6 FPS, a reduction of 25.5 FPS. The jump to 2160p High sees a further decline to 24.9 FPS, which is roughly half of the 1440p result and only about a third of the 1080p figure. This scaling pattern is typical of a GPU-bound scenario; the CPU has ample headroom, but the GPU's rendering throughput diminishes as pixel count increases.

The trend is identical across all settings. With Low settings, the average frame rate is 95.3 FPS at 1080p, 59.5 FPS at 1440p, and 32.2 FPS at 2160p. The consistent, near-linear drop indicates that the RX 570's fillrate and shading capabilities are saturated, regardless of the graphical load. The data suggests that the CPU's performance is not a factor in these results; the Ryzen 7 9800X3D, with its 8 cores and 16 threads, has the single-thread and multi-thread performance to feed the GPU well beyond the observed frame rates. The bottleneck is solely the GPU's processing power, making resolution scaling a direct reflection of the RX 570's limits.

How This Combo Ranks

The benchmark results place this combination at rank 1597 out of 1681 tested combos in Doom, putting it in the bottom 5% of all pairings. The data shows a system that is heavily constrained by its graphics processor. While the Ryzen 7 9800X3D is a top-tier CPU, its performance is irrelevant here because the RX 570 cannot translate that processing power into high frame rates. The rank is a consequence of the GPU's age and class, not the CPU's capability.

The CPU's own benchmark data shows it is a high performer, scoring 37780 on average and sitting in the 90th percentile of all CPUs. Its nearest rivals, such as the Intel Xeon 6353P and Intel Core Ultra 5 225, have average scores within 0.1% of the Ryzen. This indicates that the processor is not the source of the low ranking. Instead, the GPU's average benchmark score of 30158 and its 74th percentile placement among GPUs is the more telling metric. The combination of a top-tier CPU with a mid-range, older GPU creates a massive performance disparity that the game's frame rate data reflects directly in its low overall rank.

GPU Role

The AMD Radeon RX 570's specifications directly explain its performance in Doom. The card features a Polaris 20 chip with a base clock of 1168 MHz and a boost clock of 1244 MHz. It has 2048 shading units and 32 ROPs, paired with 4 GB of GDDR5 memory on a 256-bit bus, yielding a bandwidth of 224.0 GB/s. These characteristics point to a GPU designed for 1080p gaming at its launch, and the measured data confirms that it is still most viable at that resolution.

The 4 GB VRAM capacity is a significant factor at higher resolutions. While Doom can run at 1440p, the frame rate collapse to 33.3 FPS at Ultra settings suggests that the GPU is not only compute-bound but also likely constrained by memory capacity and bandwidth. The 224.0 GB/s bandwidth is sufficient for 1080p but struggles to feed the shaders efficiently at 1440p and 4K. The GPU's 14 nm process node and 150 W TDP are dated, and its FP32 performance of 5.095 TFLOPS is simply not enough to maintain high frame rates in a demanding scene at 1440p and above. The card's performance in this test is consistent with its hardware profile; it is a capable 1080p card that falls behind as resolution increases.

Settings Recommendations

The measured FPS data provides a clear guide for optimal settings. For a smooth 60+ FPS experience, the only viable configuration is at 1920x1080 with Low settings, which yields 95.3 FPS. The Medium preset at 1080p produces 80.2 FPS, also comfortably above the 60 FPS threshold. High settings at 1080p achieves 71.1 FPS, which is still playable. The Ultra preset at 1080p drops to 56.2 FPS, which may be acceptable but is below the ideal target for a fast-paced FPS.

At 1440p, the frame rates become less consistent. The Low preset delivers 59.5 FPS, just under the 60 FPS mark, while Medium and High produce 53.3 and 45.6 FPS, respectively. These are playable but not ideal for competitive play. The Ultra preset at 1440p falls to 33.3 FPS, which is a significant drop and not recommended for a smooth experience. At 2160p, all settings are sub-30 FPS, with the Low preset hitting only 32.2 FPS and Ultra dropping to 19.1 FPS. This resolution is not viable for this combination. The data indicates that the best experience is at 1080p with Medium or High settings, balancing visual quality with a frame rate well above 60 FPS.

Measured FPS Breakdown

At 1920x1080, the combo shows its best performance. The Low preset averages 95.3 FPS. Medium settings yield 80.2 FPS. High settings produce 71.1 FPS. The Ultra preset is the slowest at 1080p, with an average of 56.2 FPS. The spread between Low and Ultra is 39.1 FPS, showing that the GPU has headroom at this resolution to handle increased graphical loads, but also that the most demanding preset begins to tax the card.

Moving to 2560x1440, the averages drop across the board. Low settings result in 59.5 FPS. Medium sees a decrease to 53.3 FPS. High settings average 45.6 FPS. Ultra takes a significant hit, falling to 33.3 FPS. The gap between Low and Ultra here is 26.2 FPS, a narrower margin than at 1080p, which suggests that the GPU is becoming the limiting factor regardless of settings. The performance loss from 1080p to 1440p is substantial, with a 35.8 FPS drop on Low settings and a 25.5 FPS drop on High.

At 3840x2160, the GPU is overwhelmed. Low settings produce an average of 32.2 FPS. Medium drops to 26.4 FPS. High settings average 24.9 FPS. Ultra is the lowest, with an average of just 19.1 FPS. Even the lowest preset cannot maintain a playable frame rate. The difference between Low and Ultra at 4K is only 13.1 FPS, indicating that the GPU is completely saturated. The data shows that this resolution is beyond the capability of the AMD Radeon RX 570, regardless of the powerful CPU driving the system.
