Doom

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

The AMD Ryzen 7 5700G is an 8-core, 16-thread processor based on the Zen 3 architecture, built on TSMC's 7 nm process. Its base clock runs at 3.80 GHz with a boost clock of 4.60 GHz. The 16 MB of L3 cache and 512 KB per-core L2 provide the memory hierarchy that feeds the Radeon RX 7900 XT. In synthetic benchmarks, the CPU achieves a single-thread score of 2930 in Cinebench R23 and 899 in 3DMark single-thread, indicating strong per-core performance for a 2021 release. Its multithreaded Cinebench R23 score of 20755 shows the 8-core/16-thread configuration handles heavy loads, though Doom's engine is not particularly demanding on thread counts.

The CPU's percentile ranking of 83 places it above most processors in the database. Its nearest rival, the AMD Ryzen 7 6800U, scores 25706 on average, a mere 0.3% difference. The Intel Xeon D-2752TER is 0.4% behind, while the Intel Core 5 210H trails by 0.5% and the AMD Ryzen 5 7640U by 0.6%. These deltas are negligible, meaning the 5700G's compute capability is well within the same tier as those chips. For Doom, the 5700G's 16 threads are more than sufficient; the game's optimization favors high IPC and clock speed over raw core counts. The boost clock of 4.60 GHz helps sustain high frame rates, especially at lower resolutions where the CPU becomes more relevant.

The integrated Radeon Vega 8 graphics are present but unused in this configuration. The CPU's PCIe Gen 3 interface, with 16 lanes, provides the data path to the GPU. The memory bandwidth of 51.2 GB/s from dual-channel DDR4 is a potential bottleneck in theory, but the measured FPS data suggests otherwise. At 1080p with Low settings, the combo achieves 339.8 FPS, indicating the CPU is not holding back the GPU in this title. The 5700G's 65 W TDP is modest, but the performance profile shows it can drive a high-end GPU like the RX 7900 XT effectively in Doom's Vulkan-based engine.

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

The measured FPS data covers four presets — Low, Medium, High, and Ultra — across three resolutions. At 1080p, the Low preset delivers 339.8 FPS, Medium 292.3 FPS, High 251.5 FPS, and Ultra 203.4 FPS. The gap between Low and Ultra is 136.4 FPS, a 40% reduction. For competitive play, Low offers the highest headroom, but the High preset at 251.5 FPS still exceeds any 240 Hz display's refresh rate. The Ultra preset's 203.4 FPS remains above 144 Hz, making it viable for high-refresh monitors if visual fidelity is prioritized.

At 1440p, the scaling shifts. Low yields 219.4 FPS, Medium 193 FPS, High 162.1 FPS, and Ultra 130.6 FPS. The Ultra preset here drops below 144 FPS, which might be noticeable on a 144 Hz panel. High at 162.1 FPS is the sweet spot for 1440p, balancing visual quality with a comfortable margin above 144 FPS. Medium at 193 FPS is also strong, but High adds texture and shadow quality without a steep penalty — only 30.9 FPS less than Medium.

At 4K, the differences compress. Low produces 115.8 FPS, Medium 104.6 FPS, High 88.7 FPS, and Ultra 71.3 FPS. The Ultra preset falls below 72 FPS, which is inadequate for smooth gameplay on many displays. High at 88.7 FPS is playable but not ideal for fast-paced action. Medium at 104.6 FPS offers the best compromise, staying above 100 FPS while retaining moderate visual enhancements. Low at 115.8 FPS is the only preset that clears 110 FPS at 4K. For a 60 Hz display, Ultra works, but for any higher refresh, Medium is the recommended starting point at 4K.

Across all resolutions, the High preset provides the most consistent experience relative to frame rate targets. At 1080p, it is overkill for most displays. At 1440p, it is the optimal choice. At 4K, it is a step below Medium but still functional. The data suggests that High is the default recommendation for users with 144 Hz monitors at 1440p, while Medium suits 4K users seeking fluidity.

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

The FPS drop from 1080p to 4K is substantial but follows a predictable pattern. At Low settings, 1080p produces 339.8 FPS, while 4K drops to 115.8 FPS — a 65.9% reduction. At Medium, the drop is from 292.3 to 104.6 FPS, a 64.2% reduction. High goes from 251.5 to 88.7 FPS, down 64.7%. Ultra drops from 203.4 to 71.3 FPS, a 64.9% reduction. The consistency of this 64-66% decline across all presets indicates that the GPU is the primary limiting component at higher resolutions.

The relative scaling between resolutions tells a similar story. From 1080p to 1440p, the FPS drop is roughly 35-40% depending on the preset. From 1440p to 4K, the drop is another 45-50%. This compounding effect is characteristic of a GPU-bound scenario. The RX 7900 XT, with its 20 GB of GDDR6 memory and 800.0 GB/s bandwidth, is powerful, but 4K resolution demands exponentially more pixel throughput. The 5376 shading units and 192 ROPs are taxed heavily at 3840x2160.

Notably, the CPU's influence fades as resolution increases. At 1080p Low, the 339.8 FPS figure is likely near the engine's frame rate ceiling, where CPU draw-call handling becomes relevant. At 4K, the GPU's rendering workload dominates, and the 5700G's 16 threads have ample spare capacity. The data shows that the 5700G is not a bottleneck at any resolution in Doom; the RX 7900 XT determines the frame rate at 1440p and above. At 1080p, the combo is so fast that the game's internal limits may be the next constraint.

The percentage drops are also consistent with the GPU's architecture. The 5 nm Navi 31 chip scales predictably with pixel count. The 71.3 FPS at 4K Ultra is the lowest measured value, but it still exceeds 60 FPS, confirming that this combo is capable of 4K gaming in Doom, albeit with settings compromises.
