Doom

The AMD Ryzen 5 7600 and AMD Radeon RX 6800 XT combination delivers a robust performance profile in Doom, with measured frame rates that scale predictably across resolutions and settings. The data reveals a system that is well-balanced for high-refresh-rate 1440p gaming while still offering a smooth 4K experience, though the demands of Ultra settings at 4K begin to expose the GPU’s limitations.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 7600 is a 6-core, 12-thread processor built on the Zen 4 architecture, code-named Raphael. It operates on the AMD Socket AM5 platform with a base clock of 3.80 GHz and a boost clock of 5.10 GHz. This CPU’s 32 MB of shared L3 cache and 5 nm process node contribute to its strong single-thread performance, which is critical for Doom's engine. The benchmark data supports this: the processor scores 999 in 3dmark_single_thread and 3910 in passmark_single_thread, placing it in the 83rd percentile among all CPUs.

In Doom, the CPU’s impact is most visible at lower resolutions where frame rates climb dramatically. At 1080p Low settings, the combo reaches 289.3 FPS, a figure that heavily relies on the CPU’s ability to feed the GPU quickly. The Ryzen 5 7600’s multi-threaded capabilities are also relevant; its cinebench_r23_multicore score of 22992 ensures that background tasks and game logic do not bottleneck frame delivery. The 65 W TDP is modest, but the processor’s efficiency does not detract from its ability to sustain high frame rates in this title. The data indicates that the CPU is rarely the limiting factor here, as even at 4K Ultra, where the GPU is stressed, the frame rate drops to 58.8 FPS, suggesting the processor still has headroom.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 6800 XT is a RDNA 2.0 architecture GPU with 16 GB of GDDR6 memory on a 256-bit bus, providing 512.0 GB/s of bandwidth. Its boost clock of 2250 MHz and game clock of 2015 MHz position it as a high-end card, and its 4608 shading units deliver substantial raw compute power. The GPU’s benchmarks reinforce this: a passmark_g3d score of 24980 and a 3dmark_steel_nomad_dx12 score of 3689 place it in the 87th percentile of all GPUs.

In Doom, the GPU’s role becomes increasingly dominant as resolution rises. At 1080p, the frame rates are so high (215.5 FPS at High) that the GPU is likely still working hard, but the CPU is keeping pace. Moving to 1440p, the RX 6800 XT’s 16 GB VRAM and high bandwidth ensure that texture-heavy scenes remain fluid, with 139.4 FPS at High settings. The true test comes at 4K, where the GPU’s compute capabilities are fully engaged. The 58.8 FPS at Ultra settings is a direct result of the GPU’s pixel and texture rates (288.0 GPixel/s and 648.0 GTexel/s, respectively). The data shows that while the GPU is capable of 4K, it requires a settings reduction to maintain high refresh rates, which is a classic sign of a GPU-bound scenario.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured frame rates reveal a clear scaling pattern that identifies the bottleneck. At 1080p High, the combo produces 215.5 FPS. Stepping up to 1440p High drops this to 139.4 FPS, a reduction of 76.1 FPS. Moving to 4K High further reduces the average to 76.1 FPS, a 63.3 FPS drop from 1440p. This pattern is consistent across all settings. For instance, at Low settings, the drop from 1080p (289.3 FPS) to 1440p (186 FPS) is 103.3 FPS, and then to 4K (104.1 FPS) it is 81.9 FPS.

The scaling indicates that the GPU is the primary limiting component at higher resolutions. The frame rate drops are non-linear and steep, which is characteristic of GPU-bound workloads. At 1080p, the CPU has more influence, but the absolute frame rates are so high that the experience is already excellent. The data implies that for maximum performance, users should target 1080p or 1440p, where the GPU has ample headroom. At 4K, the system is firmly GPU-bound, and the frame rate differences between settings (from 104.1 FPS at Low to 58.8 FPS at Ultra) highlight the need for settings tuning to achieve a target frame rate.

Settings Recommendations

For a 60 FPS target at 4K, the data suggests using Low settings, which deliver 104.1 FPS, or Medium settings at 89.2 FPS. High settings at 76.1 FPS are also viable, but Ultra settings drop below 60 FPS to 58.8 FPS, making them unsuitable for a locked 60 FPS experience. At 1440p, all settings exceed 110 FPS, with Ultra at 110.4 FPS and High at 139.4 FPS, so the choice depends on preference for visual fidelity versus higher refresh rates. For competitive play at 1080p, Low settings at 289.3 FPS provide the highest frame rates, but even Ultra at 172.9 FPS is well above the threshold for high-refresh-rate monitors. The optimal experience per the measured data is 1440p High, which balances the 139.4 FPS average with strong visual quality, or 4K High if the user prioritizes resolution and accepts a 76.1 FPS average.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the measured average frame rates are as follows: Low settings achieve 289.3 FPS, Medium settings achieve 254.5 FPS, High settings achieve 215.5 FPS, and Ultra settings achieve 172.9 FPS. The progression shows a consistent drop of approximately 35 FPS between each settings tier, from Low to Medium (34.8 FPS), Medium to High (39 FPS), and High to Ultra (42.6 FPS). This indicates that each settings increase has a measurable, though not exponential, impact on performance.

At 2560x1440, the average frame rates are: Low settings at 186 FPS, Medium settings at 166.5 FPS, High settings at 139.4 FPS, and Ultra settings at 110.4 FPS. The gaps between settings are larger here, with a 19.5 FPS drop from Low to Medium, a 27.1 FPS drop from Medium to High, and a 29 FPS drop from High to Ultra. The increasing delta between settings suggests that the GPU is starting to feel the load at this resolution.

At 3840x2160, the average frame rates are: Low settings at 104.1 FPS, Medium settings at 89.2 FPS, High settings at 76.1 FPS, and Ultra settings at 58.8 FPS. The drops are more substantial: 14.9 FPS from Low to Medium, 13.1 FPS from Medium to High, and 17.3 FPS from High to Ultra. The data shows that at 4K, the difference between High and Ultra is the largest relative drop, pushing the frame rate below the 60 FPS threshold. This breakdown confirms that the system is most comfortable at 1080p and 1440p, with 4K requiring settings compromises to maintain smooth performance.
