Doom

The AMD Ryzen 7 5800X3D and AMD Radeon RX 7800 XT combination delivers exceptional performance in Doom, a 2016 FPS title. The data shows this pairing achieves frame rates well beyond the refresh rates of most displays, even at the demanding 4K resolution. The measured results reveal a system where the GPU becomes the primary scaling factor as resolution increases, while the CPU’s high-performance cache architecture ensures the processor never becomes a bottleneck.

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

The AMD Ryzen 7 5800X3D is built on the Zen 3 architecture, codenamed Vermeer, and features 8 cores with 16 threads. Its base clock is 3.40 GHz with a boost clock of 4.50 GHz. What distinguishes this processor in gaming workloads is its substantial 96 MB of shared L3 cache, a design choice that directly benefits game engines like the one powering Doom, which frequently access large datasets. The processor’s 3Dmark scores reinforce its capability: a single-thread score of 884 and an 8-thread score of 5906. In Doom, a title that scales well with both core count and raw single-thread speed, this configuration ensures the CPU can feed the GPU without constraint.

The processor’s performance profile is further contextualized by its benchmark rankings. It holds an 83rd percentile ranking among all CPUs, with an average benchmark score of 26574. Its nearest rivals in the dataset include the AMD EPYC 8024P, which scores 26555 (a 0.1% delta), and the Intel Core i9-11900K at 26546 (also a 0.1% delta). The Ryzen 5 7600 scores 26617, representing a -0.2% delta, and the Intel Core i9-12900HK scores 26672, a -0.4% delta. These minuscule differences indicate that the 5800X3D is performance-equivalent to these modern chips in general compute, but its gaming-specific advantage lies in the 96 MB L3 cache. In Doom’s measured FPS, the 1080p results show the CPU’s strength: at Low settings, the system hits 281.5 FPS, and at Ultra, it still manages 166.9 FPS. These numbers, especially the Low-setting figure, suggest the CPU is capable of driving frame rates that approach the limits of the engine.

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

The AMD Radeon RX 7800 XT, based on the Navi 32 chip and RDNA 3.0 architecture, is the dominant partner in this pairing for Doom. It comes equipped with 16 GB of GDDR6 memory on a 256-bit bus, delivering a memory bandwidth of 624.1 GB/s. The GPU’s game clock is 2124 MHz, with a boost clock reaching 2430 MHz. This substantial memory capacity and bandwidth are more than sufficient for Doom, a game with relatively modest VRAM requirements, meaning the GPU can operate without any memory-related stalls.

The GPU’s raw compute capabilities are impressive: it features 3840 shading units, 240 TMUs, and 96 ROPs, with a pixel rate of 233.3 GPixel/s and a texture rate of 583.2 GTexel/s. Its FP32 performance is 37.32 TFLOPS. In the benchmark database, the RX 7800 XT holds a 76th percentile ranking among all GPUs, with an average benchmark score of 32619. Its nearest rivals are the AMD FirePro S9300 X2, which scores 32540 (a 0.2% delta), and the NVIDIA P104-100, which scores 32747 (a -0.4% delta). The NVIDIA T600 Mobile scores 32849 (-0.7% delta), and the AMD FirePro S10000 scores 32388 (0.7% delta). While these rivals are not gaming-focused products, the delta values show the RX 7800 XT sits in a performance tier where small score differences translate to large FPS swings in real-world games. In Doom, the GPU’s role becomes increasingly apparent as resolution scales, moving from being partially bottlenecked at 1080p to fully utilized at 4K.

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

The measured FPS data across resolutions reveals a classic scaling pattern that identifies the RX 7800 XT as the primary limiter. At 1080p with High settings, the system achieves 207.7 FPS. Moving to 1440p High, the frame rate drops to 132.9 FPS, a reduction of 74.8 FPS. At 4K High, the average FPS falls to 73.3, which is a further drop of 59.6 FPS from the 1440p result. This progressive decline with increasing resolution is a clear indicator that the GPU is the scaling component; the CPU’s performance headroom is sufficient to maintain high frame rates at lower resolutions, but the GPU’s rendering workload grows disproportionately.

The scaling from Low settings to Ultra settings at each resolution further confirms this. At 1080p, the difference between Low (281.5 FPS) and Ultra (166.9 FPS) is 114.6 FPS, showing the GPU’s workload increases dramatically with visual fidelity. At 4K, the same comparison shows a difference of 43.9 FPS (100.3 FPS at Low versus 56.4 FPS at Ultra). The fact that the absolute FPS drop from Low to Ultra is smaller at 4K than at 1080p is significant; it indicates that at 1080p, the CPU is capable of pushing frame rates high enough that the GPU becomes the bottleneck even at Low settings, while at 4K, the GPU is fully saturated regardless of settings, and the relative impact of settings changes is compressed. This behavior confirms that for this combo, the RX 7800 XT is the performance ceiling, and the Ryzen 7 5800X3D provides ample headroom.

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

Examining the measured rows, the High preset emerges as the optimal balance between visual quality and frame rate across all resolutions. At 1080p High, the system delivers 207.7 FPS, which is well above the 144 Hz refresh rate common on high-end monitors. At 1440p High, the average FPS is 132.9, which is still suitable for high-refresh-rate gaming, though it falls just short of the 144 Hz threshold. At 4K High, the system maintains 73.3 FPS, which is playable for a fast-paced FPS, though not ideal for competitive play.

The Medium preset offers a slight performance uplift over High, with 247.5 FPS at 1080p, 156.7 FPS at 1440p, and 86.7 FPS at 4K. However, the visual quality reduction from High to Medium is typically noticeable in texture detail and shadow quality. The Ultra preset, while providing the maximum visual fidelity, incurs a significant performance penalty: 166.9 FPS at 1080p, 107.7 FPS at 1440p, and 56.4 FPS at 4K. The 4K Ultra result drops below 60 FPS, which is a critical threshold for smooth gameplay in a fast-paced shooter. Low settings yield the highest frame rates (281.5 FPS at 1080p, 181.7 FPS at 1440p, 100.3 FPS at 4K), but these settings are only recommended for esports-level competitive play where frame rate is paramount over visuals. For the majority of players, High settings at 1440p provide the best combination of image quality and performance, while 4K High remains viable for those prioritizing resolution. The data suggests that Ultra is only suitable for 1080p displays where the high frame rate compensates for the visual fidelity loss.

How This Combo Ranks — use comboRankInGame vs other tested combos

In the overall database of tested CPU/GPU combinations for Doom, this pairing of the Ryzen 7 5800X3D and Radeon RX 7800 XT ranks 640th out of 1681 tested combos. This places it in the top 38% of all systems tested, which is a strong result considering the breadth of hardware configurations in the database. The rank reflects the measured FPS data across all resolutions and settings, and it indicates that this combo outperforms the majority of systems for this specific game.

The ranking is particularly notable given the hardware’s positioning. The Ryzen 7 5800X3D’s 83rd percentile CPU ranking and the RX 7800 XT’s 76th percentile GPU ranking suggest that both components are above-average performers in their respective categories. However, the combo’s 640th rank out of 1681 (approximately the 62nd percentile) is slightly lower than either component’s individual percentile, which is expected because Doom’s performance is more heavily dependent on GPU throughput than CPU compute. The CPU’s high L3 cache and strong single-thread performance prevent it from dragging down the combo’s ranking, but the GPU’s absolute performance tier determines the final placement. This implies that while the 5800X3D has headroom to drive even faster GPUs in Doom, the RX 7800 XT is the limiting factor in this pairing. The data shows a well-matched system where neither component is severely underutilized, and the resulting rank in the 640th position reflects a balanced, high-performing configuration for this classic FPS title.
