Doom

The AMD Ryzen 7 9800X3D paired with the NVIDIA GeForce RTX 3080 delivers a commanding performance in Doom, with the data showing a clear progression from playable 4K frame rates to extremely high refresh-rate territory at 1080p. The measured results place this combination in the top third of all tested combos, indicating a well-balanced pairing that scales predictably with resolution and settings changes.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial and reveals a GPU-bound workload at higher resolutions. At High settings, the average FPS falls from 220.6 at 1920x1080 to 140.3 at 2560x1440, a reduction of 80.3 FPS. Moving further to 3840x2160, the average drops to 76.5 FPS, meaning the 4K result is roughly one-third of the 1080p figure. This steep scaling curve indicates that the GeForce RTX 3080 is the limiting component as pixel count increases, with the CPU's headroom becoming less relevant at 4K.

The pattern holds across all settings presets. At Low settings, the 1080p average of 301.7 FPS falls to 198.2 at 1440p and then to 104.1 at 4K. The Ultra preset shows the same trajectory: 183.2 FPS at 1080p, 116.1 at 1440p, and 61.1 at 4K. Interestingly, the relative drop from 1080p to 4K is steeper at Low settings (a 65.5% reduction) compared to Ultra (a 66.7% reduction), suggesting that even at lower graphical loads, the GPU remains the primary constraint at 4K. The data indicates that the Ryzen 7 9800X3D is not holding back performance at any resolution, as the FPS declines are consistent with what one would expect from a GPU-limited scenario.

GPU Role

The NVIDIA GeForce RTX 3080 operates with a base clock of 1440 MHz and a boost clock of 1710 MHz, built on the GA102 chip with 8704 shading units and 272 texture mapping units. Its 10 GB of GDDR6X memory on a 320-bit bus provides a bandwidth of 760.3 GB/s, which is ample for Doom's textures and geometry at all tested settings. The GPU's pixel rate of 164.2 GPixel/s and texture rate of 465.1 GTexel/s are directly relevant to the fill-rate demands of a fast-paced FPS.

The RTX 3080 achieves its 4K High average of 76.5 FPS with headroom, as the Ultra preset at the same resolution still manages 61.1 FPS. This suggests the GPU has sufficient memory bandwidth and compute throughput to handle the game's visual complexity. The GPU's passmark G3D score of 25086 and its 80th percentile standing among all GPUs support the measured gaming results. Compared to its nearest rivals, the RTX 3080 sits within a tight band: the AMD Radeon Pro Duo scores 0.2% lower, the AMD Radeon 880M scores 0.4% higher, and the AMD Radeon RX 7900 GRE scores 0.9% lower. The NVIDIA GeForce RTX 5070 Ti Mobile is 1% behind in average benchmark score, yet the desktop 3080's sustained performance in Doom at 4K High indicates its 10 GB frame buffer is not a limiting factor in this title.

How This Combo Ranks

This specific CPU-GPU combination ranks 527th out of 1681 tested combos in Doom, placing it in the 68.7th percentile of all configurations. The rank reflects the synergy between the Ryzen 7 9800X3D's strong single-thread performance and the RTX 3080's rasterization capabilities. The CPU's 3DMark single-thread score of 1212 and Geekbench single-core score of 3341 demonstrate the processing power needed to feed the GPU at high frame rates, particularly at 1080p where the average FPS exceeds 300 on Low settings.

The combo's rank is notable given that the CPU alone sits in the 90th percentile among all CPUs, while the GPU is in the 80th percentile among all GPUs. The combined rank of 527 out of 1681 suggests that the pairing extracts near-maximal performance from both components, as neither is disproportionately weak. The measured FPS data shows no obvious bottleneck at any resolution: 1080p Low achieves 301.7 FPS, which is close to what a high-refresh-rate monitor can display, and the progression to 4K Ultra at 61.1 FPS remains smooth and playable.

FAQ

Q: Is the CPU or GPU the primary bottleneck at 1080p Low?

A: At 1080p Low, the average of 301.7 FPS suggests the CPU provides ample headroom, and the GPU is likely the limiting factor even at this low graphical load, given the steep scaling to 4K.

CPU Role

The AMD Ryzen 7 9800X3D is an 8-core, 16-thread processor from the 9000 series, built on the Zen 5 architecture with a 4 nm process. Its base clock of 4.70 GHz and boost clock of 5.20 GHz, combined with a 96 MB shared L3 cache, provide the computational throughput needed for high-FPS gaming. The CPU's 3DMark scores show strong scaling from single-thread (1212) to 16-thread (10081), while Cinebench R23 multicore reaches 34004 and single-core 4800. These figures indicate that the processor can sustain high frame rates without becoming a bottleneck, particularly at 1080p where the measured average of 301.7 FPS on Low settings approaches the practical limits of display technology.

The CPU's PassMark multithread score of 40009 and single-thread score of 4430 reflect its balanced design, and its 90th percentile standing among all CPUs confirms top-tier performance. Compared to its nearest rivals, the Ryzen 7 9800X3D's average benchmark score of 37780 is within 0.7% of the Intel Xeon 6353P, Intel Core Ultra 5 225, Intel Core i9-13900HK, and Intel Core i5-13600KF. This tight clustering suggests that the CPU has no significant performance deficit in synthetic tests, and the gaming data supports this conclusion. The measured FPS at 1080p High (220.6) and Low (301.7) shows that the CPU can feed the RTX 3080 enough data to achieve frame rates well above 200, indicating that the processor is not the limiting factor at any resolution tested.

Settings Recommendations

The measured rows provide clear guidance for optimizing the experience based on resolution and desired frame rate. At 1920x1080, the Ultra preset delivers 183.2 FPS, which is more than sufficient for any high-refresh-rate monitor, and the High preset at 220.6 FPS offers additional headroom. For competitive play where maximum frame rate matters, the Low preset at 301.7 FPS is the best choice, though the Medium preset at 262.5 FPS balances visual quality with speed.

At 2560x1440, the High preset at 140.3 FPS is the recommended balance, as it exceeds the refresh rate of most 1440p gaming monitors while maintaining good visual fidelity. The Ultra preset at 116.1 FPS is also viable for those prioritizing image quality, and the Medium preset at 171.6 FPS is ideal for 144Hz displays. The Low preset at 198.2 FPS provides maximum smoothness but sacrifices visual detail that the game's engine can showcase.

For 3840x2160, the High preset at 76.5 FPS is the best experience, offering smooth gameplay on 60Hz displays with room to spare. The Medium preset at 91.3 FPS is also excellent for VRR displays, while the Ultra preset at 61.1 FPS remains playable for those who prioritize visual fidelity over frame rate. The Low preset at 104.1 FPS is the fastest 4K option, but the visual downgrade is significant. Across all resolutions, the High preset consistently provides the best balance of image quality and performance, with 4K High being the most demanding yet still smooth configuration at 76.5 FPS.
