Doom

The AMD Ryzen 7 5800X paired with the AMD Radeon RX 9070 XT delivers a formidable performance profile in Doom, demonstrating a clear GPU-bound trend as resolution increases. The data shows a steep FPS drop from 1080p to 4K across all settings, with the scaling pattern revealing where the system’s bottleneck lies. At 1080p with Low settings, the combo achieves 310.6 FPS, which falls to 204.5 FPS at 1440p and further to 109.1 FPS at 4K—a reduction of 34.2% and 64.9% from the 1080p baseline, respectively. This dramatic decline indicates that the Radeon RX 9070 XT’s rendering capacity is the limiting factor at higher resolutions, while the Ryzen 7 5800X’s eight cores and sixteen threads provide ample headroom to feed the GPU at lower resolutions. The scaling becomes even more pronounced under Ultra settings, where the 187.1 FPS at 1080p drops to 123.1 FPS at 1440p and 65.1 FPS at 4K, showcasing a 65.2% loss from the baseline. These numbers suggest that the CPU is not the constraint; even at 1080p Ultra, the frame rate remains high, meaning the graphics card is doing the heavy lifting. The 4K results, particularly the 65.1 FPS on Ultra, indicate that the GPU’s compute resources are saturated, as the gap between Low and Ultra settings widens from 47.5% at 1080p to 40.5% at 4K, underscoring the increased pixel shader workload.

Resolution Scaling

The resolution scaling analysis reveals a performance curve consistent with a GPU-limited configuration. From 1080p to 1440p, the average FPS across all settings drops by approximately 33-35%, with the Low preset showing a 34.1% decrease from 310.6 to 204.5 FPS. The transition from 1440p to 4K is more punishing, with the same Low preset falling 46.6% from 204.5 to 109.1 FPS, indicating that the RX 9070 XT’s 16GB of GDDR6 memory and 644.6 GB/s bandwidth are being pushed harder as pixel count quadruples. The High preset exhibits a similar pattern: 231.2 FPS at 1080p, 147.4 FPS at 1440p, and 81.9 FPS at 4K, representing cumulative drops of 36.2% and 64.6% respectively. This non-linear scaling—where the 1440p-to-4K drop (44.4% for High) exceeds the 1080p-to-1440p drop (36.2%)—points to the GPU’s pixel fill rate and memory bandwidth becoming increasingly critical at higher resolutions. The data also shows that the gap between Low and Ultra settings narrows as resolution increases: at 1080p, Ultra is 39.8% slower than Low, but at 4K, that gap expands to 40.3%, suggesting that the GPU’s shading units and ROPs are fully utilized at 4K regardless of preset. Benchmarks indicate that the RX 9070 XT, with its 4096 shading units and 128 ROPs, is the primary driver of these results, as the CPU’s performance remains consistent across resolutions, given its 84th percentile ranking among all CPUs.

How This Combo Ranks

In the context of all tested combinations for Doom, this specific pairing of the Ryzen 7 5800X and Radeon RX 9070 XT achieves a combo rank of 468 out of 1681 tested combos, placing it in the top 27.8% of all configurations. This ranking reflects a strong but not elite position, as the GPU’s 82nd percentile among all GPUs and the CPU’s 84th percentile among all CPUs combine to deliver a balanced system that excels in high-refresh-rate scenarios but falls short of the absolute top-tier builds. The nearest rivals for the GPU include the AMD Radeon Pro 575, which scores 39703 in average benchmarks, a mere 0.1% higher than the RX 9070 XT’s 39647, indicating that the RX 9070 XT is positioned at the edge of a performance tier where small deltas matter. Similarly, the CPU’s closest competitor, the AMD Ryzen 7 5800, scores 27535 with a delta of 0.3% relative to the 5800X’s 27606, showing that the 5800X offers a marginal advantage. This ranking suggests that while the combo is not at the pinnacle of performance, it sits comfortably above the median, with the measured FPS data confirming that it can handle Doom at high settings across all resolutions, albeit with compromises at 4K Ultra. The rank of 468 out of 1681 also implies that most superior combos likely pair higher-end CPUs or GPUs, but the 5800X and RX 9070 XT combination provides a coherent experience without a clear bottleneck.

Settings Recommendations

Based on the measured FPS rows, the optimal settings for this combo in Doom depend on the target resolution and desired frame rate. At 1080p, the Ultra preset delivers 187.1 FPS, which is well above the 144Hz refresh rate common in gaming monitors, making it the recommended choice for competitive play or maximum visual fidelity without sacrificing smoothness. The High preset at 231.2 FPS is also viable for those seeking even higher frame rates, but the visual gains from Ultra are worth the 19.1% performance cost. Moving to 1440p, the High preset at 147.4 FPS emerges as the best balance, as it remains above 144 FPS while offering better visuals than Medium’s 175.9 FPS or Low’s 204.5 FPS. Ultra at 1440p drops to 123.1 FPS, which is still playable but may not fully utilize a 144Hz display, so High is the recommended sweet spot. At 4K, the situation changes dramatically: Low settings yield 109.1 FPS, which is playable but visually compromised, while Medium drops to 97.9 FPS and High to 81.9 FPS. For 4K gaming, the Medium preset at 97.9 FPS offers the best compromise between visual quality and performance, as it stays above 60 FPS while providing more detail than Low. Ultra at 4K, with its 65.1 FPS, is only suitable for players who prioritize image quality over frame rate and have a display that supports adaptive sync. The data indicates that the combo is most comfortable at 1080p and 1440p, where even Ultra settings maintain triple-digit frame rates, while 4K requires careful preset selection to avoid dipping below 60 FPS.

Measured FPS Breakdown

The complete FPS breakdown across resolutions and settings provides a detailed picture of the combo’s capabilities. At 1920x1080, the average FPS ranges from 310.6 on Low to 187.1 on Ultra, with Medium at 271.4 and High at 231.2. The step-down from Low to Medium is 12.6%, from Medium to High is 14.8%, and from High to Ultra is 19.1%, indicating that each preset increment has a measurable but diminishing impact on performance. At 2560x1440, the averages are 204.5 FPS on Low, 175.9 FPS on Medium, 147.4 FPS on High, and 123.1 FPS on Ultra. The relative drops are 14.0% from Low to Medium, 16.2% from Medium to High, and 16.5% from High to Ultra, showing a more consistent scaling pattern compared to 1080p. At 3840x2160, the averages are 109.1 FPS on Low, 97.9 FPS on Medium, 81.9 FPS on High, and 65.1 FPS on Ultra. The drops here are 10.3% from Low to Medium, 16.3% from Medium to High, and 20.5% from High to Ultra, revealing that the Ultra preset at 4K imposes a heavier penalty as the GPU’s resources are increasingly taxed. Overall, the data shows that the combo can maintain high frame rates at 1080p and 1440p across all settings, but 4K gaming requires a trade-off between visual fidelity and performance, with the difference between Low and Ultra at 4K being 40.3%, compared to 39.8% at 1080p.

GPU Role

The AMD Radeon RX 9070 XT plays a central role in these results, with its 16GB of GDDR6 memory and 256-bit bus width providing a 644.6 GB/s bandwidth that is essential for handling the texture-heavy environments of Doom at high resolutions. The GPU’s boost clock of 2970 MHz and game clock of 2400 MHz, with a base clock of 1660 MHz, enable it to sustain high frame rates, as evidenced by the 3DMark Steel Nomad DX12 score of 7260. The memory clock runs at 2518 MHz, translating to 20.1 Gbps effective, which helps maintain consistent performance in scenes with heavy asset streaming. The GPU’s 4096 shading units and 128 ROPs, along with a pixel rate of 380.2 GPixel/s and texture rate of 760.3 GTexel/s, contribute to its ability to render Doom’s fast-paced action without stuttering. The FP32 performance of 48.66 TFLOPS and FP16 of 97.32 TFLOPS (2:1) further underscore its compute capability, which is relevant for the game’s dynamic lighting and particle effects. The GPU’s 82nd percentile ranking among all GPUs, with an average benchmark score of 39647, places it close to rivals like the AMD Radeon Pro 575 (39703, -0.1% delta) and the NVIDIA RTX A500 Mobile (39568, 0.2% delta), indicating that the RX 9070 XT is a mid-to-high-tier card. In Doom, the GPU’s role is decisive: at 4K Ultra, the 65.1 FPS result suggests that the card’s compute and memory subsystems are fully utilized, while at 1080p Low, the 310.6 FPS shows that the GPU is not a limiting factor, allowing the CPU to push frame rates to their maximum. The 304W TDP and dual-slot design, with 2x 8-pin power connectors and a suggested PSU of 700W, indicate a power-hungry component that delivers the performance seen in these benchmarks.
