Doom

The AMD Ryzen 7 5700 paired with the AMD Radeon RX 7900 XTX delivers a formidable 1080p and 1440p experience in Doom, but the performance curve reveals a system that is heavily optimized for high-refresh-rate gaming at those resolutions. The transition to 4K is where the data shows a significant shift in the bottleneck, moving from the CPU to the GPU. This analysis uses the measured FPS data to outline exactly what this combination achieves, how it scales, and where its strengths and limitations lie.

Resolution Scaling

The measured FPS data shows a clear and steep decline as resolution increases, which is typical for a game like Doom that is well-optimized. At 1080p with Ultra settings, the combo produces an average of 220 FPS. Moving to 1440p Ultra drops that average to 143 FPS, a 35% reduction. The jump to 4K Ultra is even more pronounced, with the average falling to 77 FPS, which is a 46% drop from 1440p and a 65% drop from the 1080p result. This scaling pattern indicates that the CPU is not the limiting factor at higher resolutions; instead, the GPU's rendering load is the primary constraint.

The data suggests that at 1080p, the Ryzen 7 5700's eight cores and 16 threads are more than capable of keeping up with the RX 7900 XTX. The high frame rates at this resolution, particularly the 345 FPS average on Low settings, point to a CPU-bound scenario where the GPU still has headroom. As resolution increases to 1440p, the frame rates remain exceptionally high, but the gap between settings narrows, signaling that the GPU is beginning to work harder. At 4K, the frame rates across all settings converge to a much tighter band, from 77 FPS on Ultra to 128 FPS on Low, which confirms that the GPU is now the definitive bottleneck. The 4K results are the most telling, as the 51 FPS difference between Low and Ultra settings is entirely due to the GPU's pixel-pushing capabilities, not the CPU.

For a player targeting 4K, this combo will deliver a playable experience, but not one that maximizes the potential of a high-refresh-rate 4K display. The 4K High setting average of 94 FPS is solid, but the 4K Ultra average of 77 FPS shows that the most demanding settings will require a compromise on frame rate. The scaling data suggests that this pairing is best suited for 1080p and 1440p gaming, where it can consistently deliver frame rates well above the 144Hz threshold, making it an ideal match for high-refresh-rate monitors at those resolutions.

GPU Role

The AMD Radeon RX 7900 XTX is the dominant component in this pairing, and its specifications directly explain the performance characteristics seen in the measured data. The GPU features 24 GB of GDDR6 memory on a 384-bit bus, providing a memory bandwidth of 960.0 GB/s. This massive bandwidth is crucial for Doom's fast-paced texture streaming and high-resolution rendering, ensuring that the GPU is never starved for data. The high memory capacity also provides ample headroom for future titles and high-resolution texture packs.

Clock speeds are another key factor. The GPU's boost clock of 2498 MHz and game clock of 2365 MHz are high for the RDNA 3.0 architecture, allowing the 6144 shading units to operate at a very rapid pace. This is reflected in the 61.39 TFLOPS of FP32 compute power, which is a theoretical measure of the GPU's raw shader throughput. In Doom, a game that is known for its efficient rendering engine, this raw power translates directly into high frame rates, particularly at 1080p and 1440p where the CPU can feed the GPU fast enough.

The data indicates that the GPU is the performance ceiling at 4K. The 4K Ultra average of 77 FPS is a direct result of the GPU's ability to process the increased pixel count. While the RX 7900 XTX is a high-end card, the data shows it is not overkill for this game at 4K Ultra. The 4K Low setting, which reduces the rendering load, achieves 128 FPS, showing that the GPU has significant headroom when the visual load is lightened. The card's 96 ray accelerators are present, but Doom's original release does not heavily utilize ray tracing, so their impact on these measured results is minimal. The GPU's role here is purely about rasterization power, and the data shows it delivers that power in spades at lower resolutions, while being the limiting factor at 4K.

Settings Recommendations

Based on the measured data, the ideal settings depend heavily on your target resolution and refresh rate. For 1080p and 1440p gaming, the Ultra preset is the clear choice. At 1440p, the 143 FPS average is high enough for a responsive and smooth experience, and the visual benefits of Ultra are substantial. At 1080p, the 220 FPS average on Ultra is excellent and leaves plenty of headroom for a high-refresh-rate monitor. There is no reason to drop below Ultra at these resolutions unless you are chasing the absolute maximum frame rates for competitive play, where the High preset offers a significant boost (269 FPS at 1080p, 174 FPS at 1440p) with a modest visual compromise.

For 4K gaming, the recommendation is more nuanced. The High preset, with an average of 94 FPS, offers the best balance between visual quality and performance. It provides a smooth experience for most players. The Ultra preset at 4K, with an average of 77 FPS, is still playable, but it dips below the 80 FPS threshold that many consider the minimum for a premium experience. If you have a 4K display with a 60Hz refresh rate, Ultra is perfectly fine. However, if you have a 4K 120Hz or 144Hz display, the High preset is the better choice to stay closer to the higher refresh rate. The Medium preset at 4K, averaging 112 FPS, is a strong alternative if you want to prioritize frame rate over maximum graphical detail, providing a gameplay experience that is both fast and visually appealing. The Low preset is not recommended for 4K, as it significantly reduces visual quality for a frame rate gain that is less noticeable at that resolution.
