Doom

The AMD Ryzen 7 5800XT paired with the AMD Radeon RX 6700 XT delivers a highly capable Doom experience, with performance scaling predictably across resolutions and settings. The data shows a system that is clearly GPU-bound at higher resolutions, while the processor’s strong multi-threaded capabilities ensure high frame rates at 1080p. The combo ranks in the 952nd position out of 1681 tested combinations, placing it in the upper-middle tier of all tested systems for this title.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial, revealing a classic GPU-bound scenario. At 1080p with Ultra settings, the combo produces 140.7 FPS, but at 4K Ultra, this falls to 47.3 FPS—a reduction of approximately 66%. This steep decline indicates that the Radeon RX 6700 XT’s rendering pipeline becomes the primary limiting factor as pixel count increases, rather than the CPU.

The scaling pattern is consistent across all settings. With High settings, the transition from 1080p (172.8 FPS) to 1440p (110.1 FPS) results in a 36% drop, while moving from 1440p to 4K (57.2 FPS) cuts performance by another 48%. This confirms that the GPU’s fill rate and memory bandwidth are stretched thin at 4K, with the 384.0 GB/s bandwidth and 192-bit bus proving adequate for 1440p but insufficient for maintaining high frame rates at 4K.

At 1080p, the CPU’s role becomes more evident. The gap between Low (230 FPS) and Ultra (140.7 FPS) settings is 89.3 FPS, showing that the Ryzen 7 5800XT can feed the GPU efficiently even at lower settings. The 8 cores and 16 threads, with a boost clock of 4.80 GHz, prevent any significant CPU bottleneck at this resolution, as evidenced by the relatively small performance delta between Low and Medium settings (31.7 FPS) compared to the larger delta between Medium and Ultra (57.6 FPS).

GPU Role

The Radeon RX 6700 XT’s specifications directly explain the measured results. With 12 GB of GDDR6 memory and a boost clock of 2581 MHz, the card provides solid baseline performance. The 40 ray accelerators and 2560 shading units contribute to the card’s ability to handle Doom’s Vulkan-based rendering, though the game’s 2016 release date means it does not heavily utilize modern ray tracing features.

The GPU’s memory configuration is a key factor in 4K performance. The 12 GB capacity is not the limiting factor, as Doom’s texture requirements are modest by modern standards. Instead, the 384.0 GB/s bandwidth and 192-bit bus width create a bottleneck at 4K, where the frame buffer demands exceed what this memory subsystem can efficiently deliver. This is evident in the 4K Ultra result of 47.3 FPS, which falls below the 60 FPS threshold for smooth gameplay.

The clock speeds show minimal impact on scaling. The base clock of 2321 MHz and game clock of 2424 MHz provide consistent performance across resolutions, but the card’s 13.21 TFLOPS FP32 throughput is insufficient for 4K Ultra in this title. Interestingly, the GPU’s 77th percentile ranking among all GPUs suggests it performs well relative to its peers, yet the measured data shows it struggles at 4K, indicating that Doom’s rendering workload is particularly demanding on fill rate rather than compute.

The 1440p High setting also offers a 22.4 FPS advantage over 1440p Ultra (87.7 FPS), making it the optimal balance of performance and quality.

At 1080p, High settings (172.8 FPS) are recommended for competitive play, as they provide a 32.1 FPS improvement over Ultra (140.7 FPS) while retaining most visual features. The jump from High to Medium (198.3 FPS) adds 25.5 FPS but reduces visual quality, making High the preferred choice for most users. For users with 144Hz monitors, 1080p Medium (198.3 FPS) or Low (230 FPS) settings are viable options to maximize frame rates.

At 4K, the data indicates that Medium settings (70.6 FPS) are the highest quality option that maintains playable performance. High settings (57.2 FPS) and Ultra (47.3 FPS) fall below the 60 FPS threshold, making them less desirable for smooth gameplay. Low settings (78.4 FPS) at 4K are also viable but sacrifice significant visual quality for only 7.8 FPS over Medium.

CPU Role

The AMD Ryzen 7 5800XT’s specifications are well-suited for Doom. With 8 cores, 16 threads, and a boost clock of 4.80 GHz, the CPU provides ample processing power to maintain high frame rates even at 1080p Low settings (230 FPS). The 32 MB L3 cache and DDR4 memory support with 51.2 GB/s bandwidth ensure efficient data flow to the GPU.

The CPU’s synthetic benchmark scores support its gaming performance. A Cinebench R23 multi-core score of 23794 and single-core score of 3359 indicate strong multi-threaded and single-threaded capabilities. The 3DMark 16-thread score of 7683 and max-thread score of 7680 show excellent scaling across cores, which is relevant for Doom’s multi-threaded rendering engine.

The CPU’s nearest rivals in synthetic benchmarks show minimal performance differences, with deltas of only 0.1-0.3% against the AMD Ryzen 7 PRO 5755GE, AMD Ryzen 7 6800HS, AMD Ryzen AI 7 PRO 360, and AMD Ryzen 7 7840H. This indicates that the 5800XT is competitively positioned within its performance class. However, the measured FPS data shows that the CPU is rarely the bottleneck in Doom, as even at 1080p Low settings, the GPU’s output of 230 FPS is the limiting factor, not the CPU’s ability to feed frames.
