Doom

The AMD Ryzen 9 9900X3D and Radeon RX 7800 XT combination delivers a thoroughly playable Doom experience across all tested resolutions, with the data showing a clear shift from a CPU-limited state at 1080p to a GPU-bound scenario at 4K. The benchmark results indicate that this pairing is exceptionally well-balanced for this title, offering high frame rates even at maximum settings, though the scaling patterns reveal distinct bottlenecks depending on the resolution.

Resolution Scaling

The measured FPS data demonstrates that Doom's performance scales predictably with resolution, but the magnitude of the drop tells a significant story about component utilization. At 1080p with Low settings, the combo achieves an average of 284 FPS. Moving to 1440p Low drops this to 184 FPS, a reduction of 100 FPS, and at 4K Low the average falls to 99 FPS. This steep decline from 1080p to 4K suggests that the Radeon RX 7800 XT's rendering capabilities become the primary constraint as pixel count increases, while the Ryzen 9 9900X3D's processing power is more than sufficient to feed the GPU at lower resolutions.

The pattern is consistent across all settings presets. At High settings, the combo delivers 209 FPS at 1080p, which is an exceptionally high frame rate that indicates the CPU is not the limiting factor at this resolution. The drop to 135 FPS at 1440p High and then to 73 FPS at 4K High shows a progressive scaling that is characteristic of GPU-bound workloads. The 1080p to 1440p transition at High settings results in a 74 FPS decline, while the 1440p to 4K transition at High settings produces a 62 FPS decline, demonstrating that the GPU is becoming increasingly saturated as resolution climbs.

At Medium settings, the measured data includes min and max FPS values, providing additional insight. At 1080p Medium, the average is 247 FPS with a minimum of 210 FPS and maximum of 284 FPS. The 1440p Medium result shows an average of 160 FPS with a minimum of 136 FPS and maximum of 184 FPS. At 4K Medium, the average drops to 87 FPS with a minimum of 74 FPS and maximum of 100 FPS. The narrowing of the min-max range at 4K Medium (74-100 FPS) compared to 1080p Medium (210-284 FPS) indicates that the GPU is working closer to its sustained capacity at higher resolutions, reducing frame time variance.

The Ultra preset data reveals the most significant performance cost. At 1080p Ultra, the average is 171 FPS, which drops to 110 FPS at 1440p Ultra and further to 60 FPS at 4K Ultra. The 4K Ultra result sits right at the edge of smooth gameplay, suggesting that this setting is only viable for players who can tolerate exactly 60 FPS average. The scaling from 1080p Ultra to 4K Ultra represents a 111 FPS drop, which is the largest absolute decline across all settings presets, confirming that Ultra settings place the heaviest load on the GPU.

The data suggests that the Ryzen 9 9900X3D is not the bottleneck at any resolution. Even at 1080p Low, where the CPU would typically be taxed most heavily, the combo achieves 284 FPS, indicating that the processor has significant headroom. The limiting component is clearly the Radeon RX 7800 XT at 4K, where the GPU's compute and memory bandwidth are fully utilized, while at 1080p and 1440p the GPU still has capacity to spare, resulting in extremely high frame rates.

GPU Role

The Radeon RX 7800 XT's specifications play a direct role in the measured Doom performance. The GPU features 16 GB of GDDR6 memory on a 256-bit bus, providing a memory bandwidth of 624.1 GB/s. This substantial memory capacity and bandwidth are sufficient for Doom's requirements at all tested resolutions, as evidenced by the consistent frame rates even at 4K Ultra settings. The 16 GB frame buffer ensures that texture data and geometry at high resolutions do not exceed available memory, preventing potential stuttering or texture pop-in that could occur with smaller memory pools.

The GPU's clock speeds are also relevant to the performance data. The base clock is 1295 MHz, with a boost clock of 2430 MHz and a game clock of 2124 MHz. The game clock, which represents typical sustained clock speeds during gaming workloads, is notably higher than the base clock, indicating that the GPU can maintain elevated frequencies under load. The measured FPS results show that this clock behavior translates to strong performance, with the combo achieving 171 FPS at 1080p Ultra, demonstrating that the GPU can sustain high clock speeds while processing demanding rendering workloads.

The RDNA 3.0 architecture of the RX 7800 XT, built on a 5 nm process at TSMC, provides the foundation for the GPU's capabilities. With 3840 shading units, 240 texture mapping units, and 96 render output units, the GPU has substantial processing resources. The 60 ray tracing cores contribute to the GPU's feature set, though Doom's rendering workload primarily relies on traditional rasterization. The GPU's pixel rate of 233.3 GPixel/s and texture rate of 583.2 GTexel/s provide the throughput necessary for the high frame rates observed at 1080p and 1440p.

The GPU's FP32 performance of 37.32 TFLOPS, with FP16 performance also at 37.32 TFLOPS (1:1 ratio), indicates balanced compute capabilities. The Radeon RX 7800 XT's average benchmark score of 11627 and its percentile rank of 51 among all GPUs place it in the middle of the performance spectrum. This mid-range positioning is reflected in the Doom results, where the GPU delivers playable frame rates at 4K but cannot achieve the extreme frame rates that top-tier GPUs might manage at lower resolutions. The measured data shows that the GPU becomes the limiting factor at 4K, with the 1080p to 4K scaling at High settings resulting in a 136 FPS drop, confirming that the RX 7800 XT's rendering capabilities are the primary constraint at higher resolutions.
