Doom

The AMD Ryzen 9 9900X and NVIDIA GeForce RTX 5080 combination delivers exceptional performance in Doom, with benchmark data showing all tested resolutions and presets comfortably exceeding the 60 FPS playability threshold. This pairing of a 12-core Zen 5 processor with a Blackwell 2.0 GPU produces average frame rates ranging from 89.4 FPS at 4K Ultra to 423.4 FPS at 1080p Low, positioning the system as a top-tier performer for this classic FPS title.

Similar Performance Alternatives

The CPU and GPU each have close competitors based on aggregate benchmark scores, which helps contextualize how other hardware might behave in this game. For the AMD Ryzen 9 9900X, the nearest rival is the AMD EPYC 9015, which scores 57,555 compared to the 9900X’s 57,498 average — a negligible 0.1% difference. The AMD EPYC 7313 trails by just 0.2% with a score of 57,399, while the Intel Core i9-14900 leads by 1.1% at 58,115. The Intel Xeon Platinum 8260M is 1.4% ahead at 58,323. These four processors essentially bracket the 9900X within a 1.5% performance band, meaning any of them would produce nearly identical CPU-bound frame rates in Doom.

On the GPU side, the RTX 5080’s nearest rival is the AMD Radeon 8060S, which scores 55,757 versus the 5080’s 56,083 — a 0.6% gap. The AMD Radeon RX 6750 GRE 12 GB is 0.7% behind at 55,698, and the AMD Radeon Pro W5700X trails by 2.3% at 54,828. Interestingly, the AMD Radeon RX 9070 GRE is 2.2% ahead at 57,367, making it the only rival in this group that outperforms the RTX 5080 on average benchmark score. For Doom specifically, these GPU alternatives would deliver frame rates within a few percent of the measured 112.5 FPS at 4K High, assuming the CPU remains identical.

The percentile rankings reinforce this picture: the Ryzen 9 9900X sits in the 92nd percentile among all CPUs, while the RTX 5080 ranks in the 87th percentile among all GPUs. Both components are firmly in the upper tier of hardware, though the CPU has a slightly stronger relative standing. This means that in CPU-light scenarios like Doom at lower resolutions, the GPU will likely be the limiting factor, while at higher resolutions both components contribute proportionally.

CPU and GPU Roles

Doom’s frame rates scale dramatically with resolution, revealing how the CPU and GPU share the workload. At 1080p, the RTX 5080 is heavily utilized, producing 423.4 FPS on Low settings. Moving to 1440p drops this to 275.5 FPS — a 35% reduction — and 4K Low yields 150.1 FPS, another 45% decline. This steep scaling indicates that the GPU becomes progressively more dominant as pixel count increases, while the CPU maintains sufficient headroom to feed the graphics card even at 4K.

The settings presets tell a similar story. At 1080p, the gap between Low (423.4 FPS) and Ultra (254.5 FPS) is 168.9 FPS, representing a 40% performance cost for maximum visual quality. At 1440p, the spread narrows to 113.1 FPS (275.5 Low versus 162.4 Ultra), and at 4K it shrinks further to 60.7 FPS (150.1 Low versus 89.4 Ultra). This pattern confirms that at higher resolutions, the GPU’s rendering workload dominates, making the difference between settings presets relatively smaller in percentage terms. The CPU’s role is most visible at 1080p Low, where the 423.4 FPS result approaches the practical limits of the processor’s ability to feed frames.

Benchmark data shows the Ryzen 9 9900X excels in multi-threaded workloads, with a Cinebench R23 multicore score of 32,172 and a Geekbench multicore score of 22,174. The single-core performance is also strong at 2,253 in Cinebench R23, which matters for Doom’s primary game thread. However, the 3DMark 2-thread score of 2,519 suggests that even at 1080p Low, the GPU is the bottleneck — the CPU can deliver far more frames than the 423.4 FPS observed, but the RTX 5080 reaches its limit first.
