Doom

The AMD Ryzen 9 5900X paired with the AMD Radeon RX 570 produces a predictable yet telling performance profile in Doom. The data reveals a system where the legacy Polaris GPU is the clear bottleneck, with the Zen 3 processor’s immense headroom going largely unused. This analysis breaks down the measured frames per second (FPS) across resolutions and settings, examines the hardware's role, and contextualizes the combo's standing against other tested configurations.

Resolution Scaling

The measured FPS data shows a steep and consistent drop as resolution increases, a hallmark of GPU-bound rendering. At 1080p with High settings, the combo achieves 71 FPS. Moving to 1440p High, the frame rate falls to 43.6 FPS, a reduction of 27.4 FPS (roughly 38.6% lower). The jump to 2160p High further cripples performance, landing at just 22.8 FPS, which is 48.2 FPS below the 1080p result. This scaling pattern across the board—from Low to Ultra—indicates that the RX 570's rendering throughput is the primary constraint.

The delta between resolutions is more pronounced at higher settings. For instance, at 1080p Low, the system produces 95.5 FPS, but at 2160p Low, it drops to 31.7 FPS. This 63.8 FPS difference is substantial. At Ultra settings, the spread is 56.2 FPS at 1080p down to 18.8 FPS at 2160p, a 37.4 FPS gap. The data implies that while the 5900X can easily feed frames at lower resolutions, the RX 570’s fill rate and memory bandwidth are overwhelmed as pixel count increases, making the GPU the definitive limiting component. The 4K results, all below 32 FPS, are not playable for a fast-paced FPS, confirming that this resolution is out of reach for this hardware pairing in Doom.

Settings Recommendations

Benchmark results indicate that the "Sweet Spot" for this combination is the 1080p Medium preset. Here, the system delivers 83.8 FPS, which is a 17.9% improvement over the High preset’s 71 FPS, while only sacrificing some visual fidelity. The Low preset at 1080p reaches 95.5 FPS, but the jump from Low to Medium (12.3 FPS) is less significant than the jump from High to Ultra (a drop of 14.8 FPS), suggesting Medium offers the best balance between performance and visual quality.

At 1440p, the situation changes. The High preset produces 43.6 FPS, which is playable but not ideal for competitive play. Dropping to Medium yields 50.8 FPS, a 16.5% increase, but still leaves the system below the 60 FPS threshold. The Low preset at 1440p achieves 61.8 FPS, which is the only way to get a smooth 60+ FPS experience at this resolution. For 4K, the data shows that even Low settings (31.7 FPS) cannot provide a fluid experience, making 4K unsuitable for active gameplay. The recommendation is to prioritize 1080p Medium for the best experience, or 1440p Low if higher resolution is desired over graphical detail.

GPU Role

The AMD Radeon RX 570, built on the Polaris 20 chip with GCN 4.0 architecture, is the performance anchor in this pairing. Its 4 GB of GDDR5 memory on a 256-bit bus provides 224.0 GB/s of bandwidth, which is a limiting factor at higher resolutions. The card’s clocks are set at a base of 1168 MHz and a boost of 1244 MHz, with memory running at 1750 MHz (7 Gbps effective). These specifications, while capable for 1080p in 2017, struggle with the demands of Doom at modern resolutions.

The GPU’s benchmark scores reflect its mid-range standing. Its average benchmark score is 30158, placing it in the 74th percentile of all GPUs. Interestingly, its nearest rivals include the NVIDIA GeForce RTX 5060 (deltaPct 0.2, score 30109) and the AMD Radeon RX 7700 XT (deltaPct 0.2, score 30097), which are significantly newer and more powerful cards. This proximity in average score is misleading, as those scores likely come from different test suites. In Doom, the RX 570’s 5.095 TFLOPS of FP32 performance is simply not enough to maintain high frame rates at 1440p or 4K. The data shows that the GPU’s fill rate is the bottleneck, as evidenced by the severe FPS drops when resolution scales.

How This Combo Ranks

Within the benchmark database, this specific combination of the AMD Ryzen 9 5900X and the AMD Radeon RX 570 ranks 1588 out of 1681 tested combos for Doom. This places the pairing in the bottom 5.5% of all configurations, a poor standing that underscores the significant imbalance between the high-end CPU and the older, lower-tier GPU. The rank is a direct consequence of the GPU’s limitations, as the combo’s performance is far below what the CPU is capable of supporting.

The low rank is not a reflection of the CPU’s capability, but rather evidence of the GPU’s age and performance class. The 5900X is a top-tier processor, but it cannot compensate for the RX 570’s inability to render frames quickly enough. This data suggests that users with this combo are leaving a massive amount of performance untapped, as the CPU is likely idle waiting for the GPU to complete its work. The ranking highlights that for Doom, the choice of GPU is far more critical than the CPU, and this specific pairing is severely hamstrung by its graphics card.

CPU Role

The AMD Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture (codename Vermeer). It operates at a base clock of 3.70 GHz and a boost clock of 4.80 GHz, with a 64 MB L3 cache. This is an exceptionally powerful CPU, as shown by its benchmark scores: it achieves a Cinebench R23 multi-core score of 33150 and a single-core score of 4680. Its average benchmark score is 39453, placing it in the 90th percentile of all CPUs, with rivals like the Intel Core i7-13700 (deltaPct -1, score 39857) and AMD Ryzen 7 PRO 8845HS (deltaPct -0.7, score 39747) being extremely close competitors.

However, in Doom, the CPU’s role is minimal due to the GPU bottleneck. The measured FPS data shows that the frame rate is almost entirely dependent on the GPU’s settings and resolution, not the CPU’s processing power. For example, at 1080p Low, the CPU could theoretically push hundreds of frames, but the RX 570 caps the output at 95.5 FPS. The 5900X’s 12 cores and high clock speeds are simply not exercised by this game at these settings. The data implies that the CPU is functionally a bystander, providing no performance benefit over a much cheaper processor in this specific configuration. The bottleneck is so severe that the CPU’s impressive multi-threaded capabilities are irrelevant to the final frame rate.
