Doom

The AMD Ryzen 5 5600F paired with the NVIDIA GeForce RTX 4090 delivers exceptional performance in Doom, achieving triple-digit frame rates even at 4K Ultra settings. The benchmark data shows this combination ranks in the top 10% of all tested combos, with the GPU proving to be the dominant performance driver across all resolutions.

Resolution Scaling

The performance scaling from 1080p to 4K reveals a classic GPU-bound scenario. At 1920x1080 with Low settings, the combo produces 293 FPS average, while the same settings at 3840x2160 drop to 156 FPS — a 46.8% reduction. This substantial drop indicates that the RTX 4090's rendering workload increases dramatically with pixel count, while the Ryzen 5 5600F's six cores and twelve threads provide more than enough processing headroom at lower resolutions.

The scaling pattern becomes even more telling when examining High settings. The transition from 1080p High (263 FPS) to 1440p High (211 FPS) represents a 19.8% decrease, while moving from 1440p High to 4K High (115 FPS) shows a steeper 45.5% drop. This non-linear scaling confirms that the GPU's fill rate and memory bandwidth become increasingly critical as resolution rises, with the 4K resolution pushing the RTX 4090's 24 GB of GDDR6X memory and 1.01 TB/s bandwidth to their practical limits.

Ultra settings demonstrate the most dramatic resolution sensitivity. The combo achieves 245 FPS at 1080p Ultra but falls to 173 FPS at 1440p Ultra (−29.4%) and further to 94 FPS at 4K Ultra (−45.7% from 1440p). The 4K Ultra result, while still highly playable, shows that even the flagship Ada Lovelace GPU faces significant challenges when combining maximum quality settings with UHD resolution in Doom's fast-paced environments.

The data indicates that the Ryzen 5 5600F is never the limiting factor in this configuration. Even at 1080p Low, where CPU overhead typically becomes more prominent, the combo still achieves 293 FPS, suggesting the processor's 3.00 GHz base clock and 4.00 GHz boost clock provide adequate single-thread performance for Doom's engine. The 32 MB shared L3 cache also helps maintain consistent frame delivery across all resolution and settings combinations.

GPU Role

The NVIDIA GeForce RTX 4090 serves as the primary performance driver in this Doom configuration, with its massive specifications directly influencing the measured frame rates. The GPU's 16,384 shading units and 512 texture mapping units provide the raw compute throughput necessary for Doom's particle effects and dynamic lighting at high resolutions. The 176 ROPs handle pixel output efficiently, with a pixel rate of 443.5 GPixel/s enabling the high fill rates observed at 1080p and 1440p.

The Ada Lovelace architecture's 128 ray tracing cores and 512 tensor cores, while not directly benchmarked in Doom's standard rendering path, contribute to the GPU's overall processing capabilities. The 82.58 TFLOPS FP32 performance provides substantial headroom for the game's compute shaders and post-processing effects, particularly at Ultra settings where the frame rate drops to 94 FPS at 4K.

Memory configuration plays a crucial role in the resolution scaling observed. The 24 GB GDDR6X VRAM with 384-bit bus width delivers 1.01 TB/s bandwidth, which proves essential at 4K resolution where texture data demands increase exponentially. The memory clock of 1313 MHz (21 Gbps effective) ensures that the GPU's processing units never starve for data, though the scaling from 1440p to 4K still shows a 45.5% performance drop at High settings, indicating bandwidth constraints at the highest pixel counts.

The GPU's clock behavior — base 2235 MHz and boost 2520 MHz — demonstrates that the card maintains high operating frequencies under load. This is particularly evident in the 1080p results, where the combo achieves 293 FPS at Low settings, suggesting the GPU is operating at or near its boost clock to sustain such high frame rates. The 450 W TDP and triple-slot cooling solution enable sustained performance without thermal throttling, as evidenced by the consistent frame rates across all tested configurations.
