Doom

The AMD Ryzen 7 7800X3D paired with the AMD Radeon RX 6700 XT delivers a highly capable Doom experience, with the data showing a clear hierarchy where resolution and preset choices dictate performance. The measured results indicate that this combination is well-suited for high-refresh-rate 1080p and 1440p play, while 4K remains viable at adjusted settings.

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

The AMD Ryzen 7 7800X3D is an 8-core, 16-thread processor based on the Zen 4 architecture, running on the AMD Socket AM5 platform. Its base clock is 4.20 GHz with a boost clock of 5.00 GHz, and it features a substantial 96 MB of shared L3 cache. This cache configuration is particularly relevant for gaming workloads, as it reduces latency when accessing frequently used data.

In synthetic benchmarks, the processor demonstrates strong multi-threaded performance with a Cinebench R23 multicore score of 29149 and a Geekbench multicore score of 15101. Single-thread performance is equally solid, with a Cinebench R23 singlecore score of 4115 and a Geekbench singlecore score of 2725. The CPU’s overall average benchmark score of 31580 places it in the 87th percentile among all CPUs, indicating it is a top-tier performer.

The data shows that the 7800X3D is not the limiting factor in this game. At 1080p with Low settings, the system achieves 227.7 FPS, a figure that is heavily influenced by CPU capability. The processor’s 16 threads and high core clocks ensure that frame delivery remains consistent even when the GPU is not fully taxed. The nearest rivals in average score include the Intel Core i7-12700F (deltaPct 0.1), AMD Ryzen 9 5980HX (deltaPct 0.3), and AMD Ryzen 7 8700G (deltaPct 0.6), all of which are statistically close, but the 7800X3D’s cache advantage typically favors gaming scenarios.

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

Examining the High preset across resolutions reveals a clear scaling pattern. At 1920x1080, the system averages 167.4 FPS. Moving to 2560x1440, this drops to 109.3 FPS, a reduction of 58.1 FPS. At 3840x2160, the average falls further to 60.8 FPS, representing a 106.6 FPS decrease from 1080p.

This scaling behavior indicates that the GPU becomes the primary bottleneck as resolution increases. At 1080p, the CPU’s strong single-thread performance and large cache allow the GPU to operate near its maximum output. However, the RX 6700 XT, with its 2560 shading units and 13.21 TFLOPS FP32 performance, cannot maintain the same frame rates when pixel count quadruples. The data shows that the GPU’s workload scales predictably with resolution, while the CPU’s contribution remains relatively constant.

The difference between Low and Ultra settings at each resolution further confirms this. At 1080p, Low yields 227.7 FPS and Ultra yields 137.4 FPS, a 90.3 FPS gap. At 4K, the same settings produce 83.3 FPS and 50.7 FPS, a 32.6 FPS gap. This narrowing gap at higher resolutions suggests that the GPU is increasingly saturated, leaving less headroom for settings to impact performance.

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

At 1920x1080, the system delivers its highest frame rates. Low settings produce an average of 227.7 FPS, Medium drops to 202.4 FPS, High yields 167.4 FPS, and Ultra reduces performance to 137.4 FPS. All of these figures are well above the 60 FPS threshold, making this resolution ideal for high-refresh-rate displays.

Moving to 2560x1440, the averages remain strong but show a clear step down. Low settings achieve 152 FPS, Medium follows at 128.1 FPS, High maintains 109.3 FPS, and Ultra falls to 92.4 FPS. The 1440p results indicate that the system can handle competitive play at Medium or High settings without sacrificing fluidity.

At 3840x2160, performance becomes more constrained. Low settings average 83.3 FPS, Medium drops to 68.6 FPS, High yields 60.8 FPS, and Ultra falls to 50.7 FPS. The Ultra preset at 4K is the only measured configuration that dips below the 60 FPS mark, suggesting that users targeting 4K should consider Medium or High settings for a smoother experience.

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

The AMD Radeon RX 6700 XT is built on the RDNA 2.0 architecture with the Navi 22 chip, manufactured on a 7 nm process. It features 12 GB of GDDR6 memory on a 192-bit bus, providing 384.0 GB/s of bandwidth. The GPU’s base clock is 2321 MHz, with a game clock of 2424 MHz and a boost clock of 2581 MHz.

In synthetic benchmarks, the GPU achieves a 3DMark Steel Nomad DX12 score of 2435 and a Passmark G3D score of 19786. Its average benchmark score of 33721 places it in the 77th percentile among all GPUs. The nearest rivals include the AMD Radeon RX 6800 (deltaPct 0.7) and the NVIDIA RTX A5000 (deltaPct 1.3), while the AMD Radeon HD 7950 and RX 480 show negative deltas of -1%, indicating the 6700 XT outperforms them.

The GPU’s memory capacity and bandwidth are sufficient for the demands of Doom at all tested resolutions. At 4K Ultra, the game uses enough VRAM to maintain 50.7 FPS, and the 384.0 GB/s bandwidth ensures that texture streaming does not become a bottleneck. The 40 ray accelerators and 2560 shading units provide the raw compute power needed for the game’s rendering, though the data shows that Ultra settings at 4K push the GPU to its limits.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the optimal settings depend on the target resolution and desired frame rate. At 1920x1080, all presets deliver playable performance, but Ultra at 137.4 FPS offers a substantial visual upgrade over Low at 227.7 FPS. For users with high-refresh-rate monitors, Medium at 202.4 FPS strikes a balance between visual fidelity and frame rate.

At 2560x1440, High settings at 109.3 FPS provide a smooth experience that is well-suited for most gaming scenarios. Ultra at 92.4 FPS remains viable for those prioritizing image quality, while Low at 152 FPS is ideal for competitive play where maximum frame rates are preferred.

At 3840x2160, the data suggests that Medium or High settings are the best choices. High yields 60.8 FPS, which is just above the 60 FPS threshold, while Medium achieves 68.6 FPS, providing a small buffer. Ultra at 50.7 FPS is below this threshold and may result in less fluid motion. Low at 83.3 FPS is the highest-performing 4K preset but sacrifices significant visual quality. For the best overall experience at 4K, Medium settings offer the most balanced combination of performance and fidelity.
