Doom

The AMD Ryzen 7 5700G and NVIDIA GeForce RTX 5070 Ti pairing presents a fascinating study in bottleneck dynamics within Doom. The 5700G, an 8-core, 16-thread Zen 3 part with a base clock of 3.80 GHz and a boost clock of 4.60 GHz, is a capable mid-range processor. Its Cinebench R23 multi-core score of 20755 places it in the 83rd percentile of all CPUs, indicating strong sustained throughput. However, the RTX 5070 Ti is a high-end Blackwell 2.0 GPU with 8960 shading units and a boost clock of 2452 MHz, which produces 43.94 TFLOPS of FP32 compute. The data reveals that this GPU is powerful enough to expose the CPU's limitations at lower resolutions, while at 4K, the pendulum swings entirely toward the graphics card.

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

The 5700G's architecture, Cezanne, is based on the Zen 3 design, which offers solid single-thread performance. This is crucial for a game like Doom, which is known for its fast-paced, single-thread-heavy game logic. The processor's 3dmark_single_thread score of 899 and Cinebench R20 single-core score of 1230 suggest that it can handle the game's primary thread without severe stuttering. However, the pattern of FPS results across resolutions indicates that the CPU is the limiting factor at 1080p. With a 3dmark_8_threads score of 5648, the processor has enough multi-threaded headroom, but the game's engine appears to be heavily reliant on a few cores. The fact that the FPS at 1080p Low (346.8) is only about 23% higher than at 1080p High (281.9) suggests that even when lowering the GPU load, the CPU cannot push the frame rate substantially higher, pointing to a hard ceiling imposed by the processor's clock speed and IPC. The 16 MB of L3 cache is also a factor, as it provides a moderate amount of fast memory for the game's data, but it is not enough to prevent the CPU from becoming the primary constraint in lower-resolution scenarios. The CPU's boost clock of 4.60 GHz is respectable, but it is simply not high enough to keep pace with the 5070 Ti's raw rendering capability when the resolution drops.

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

The data shows a clear trade-off between visual fidelity and frame rate, and the optimal preset depends heavily on the target resolution. At 1080p, the High preset delivers 281.9 avg FPS, which is already far beyond the refresh rate of most monitors. Moving to Ultra drops this to 230.1 avg FPS, a decrease of 18.4%, but still maintains a hugely playable frame rate. The Medium preset offers 325.4 avg FPS, which is a 15.4% uplift over High, but the visual difference between High and Medium is often negligible in fast-paced action. For 1440p, the High preset yields 183.4 avg FPS, which is ideal for high-refresh-rate 1440p panels. Ultra at 1440p still provides 147.7 avg FPS, which is smooth, but the step down to High seems the better balance, as it retains a significant FPS buffer. At 4K, the story changes. The High preset averages 98.1 FPS, which is just shy of a perfect 100 FPS experience. The Ultra preset drops to 78.7 avg FPS, which is still playable but introduces more noticeable frame pacing issues. Given the data, the High preset provides the most consistent experience across all three resolutions, offering a substantial frame rate advantage over Ultra while not sacrificing the visual quality that makes Doom's environments so detailed. The Low preset, while yielding the highest FPS at every resolution, is not recommended for a game that relies on atmospheric lighting and shadows, as it would diminish the experience.

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

The scaling from 1080p to 4K reveals a classic transition from CPU-bound to GPU-bound performance. At 1080p High, the system produces 281.9 FPS. Moving to 1440p High, the frame rate drops to 183.4 FPS, a reduction of 34.9%. This is a substantial drop, but it is expected as the GPU begins to work harder. However, the most telling data point is the transition from 1440p to 4K. At 4K High, the average FPS is 98.1, a 46.5% decrease from the 1440p figure. This steep drop-off indicates that the GPU is now the dominant limiting factor, as the RTX 5070 Ti's 16 GB of GDDR7 memory and 896.0 GB/s of bandwidth are being fully exercised. At 1080p Low, the system hits 346.8 FPS. At 4K Low, it drops to 134.7 FPS, a 61.2% decrease. This massive drop at low settings proves that the CPU was holding back the GPU at 1080p; when the GPU load is light, the CPU cannot generate frames any faster. But as the resolution increases, the GPU's rendering workload scales up, and the CPU's limitations become less relevant. The performance gap between 1080p and 1440p is smaller than the gap between 1440p and 4K, which strongly suggests that the system is CPU-limited at 1080p and GPU-limited at 4K, with 1440p being the transition zone.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of the AMD Ryzen 7 5700G and the NVIDIA GeForce RTX 5070 Ti achieves a rank of 164 out of 1681 tested combos in Doom. This places it in the top 10% of all tested systems, which is a strong result. The rank of 164 is driven by the GPU's immense power, as the RTX 5070 Ti's Passmark G3D score of 32974 puts it in the 87th percentile of all GPUs. The CPU, while not a top-tier part, is not a significant drag on the overall ranking due to the game's nature. The 5700G's nearest rival, the AMD Ryzen 7 6800U, has a deltaPct of -0.3, meaning the 5700G is virtually identical in synthetic benchmarks. However, the 6800U is a mobile part, while the 5700G is a desktop chip, so the power delivery and sustained clock speeds may differ. The Intel Core 5 210H is 0.5% ahead in average benchmark score, but this difference is negligible. The ranking of 164 is impressive, but it is important to note that the combo is likely held back in the ranking by the CPU's performance in other, more CPU-intensive games. In Doom, the high frame rates at 1080p and 1440p are evidence of the GPU's ability to brute-force the rendering, but the 5700G ensures that the system does not fall too far down the list.
