Doom

The AMD Ryzen 7 5700G pairs a Zen 3 architecture with 8 cores and 16 threads, running at a base clock of 3.80 GHz and a boost clock of 4.60 GHz. This is a 65 W part on the AMD Socket AM4 platform, built on TSMC's 7 nm process with a 16 MB L3 cache. In synthetic tests, its multi-threaded capability is clear: it scores 20,755 in Cinebench R23 multi-core and 8,717 in Cinebench R20 multi-core, while single-thread performance reaches 2,930 in Cinebench R23. The CPU's 3DMark results scale from 899 in single-thread to 6,629 in the 16-thread test, showing strong scaling across its 16 threads. Its average benchmark score of 25,626 places it in the 83rd percentile of all CPUs. Against its nearest rivals, the 5700G is essentially tied with the AMD Ryzen 7 6800U (deltaPct -0.3), slightly ahead of the Intel Xeon D-2752TER (deltaPct 0.4), and marginally ahead of the Intel Core 5 210H (deltaPct 0.5) and AMD Ryzen 5 7640U (deltaPct 0.6). These narrow deltas suggest the 5700G's core architecture and clock speeds are well balanced for general compute, but the game's results will reveal whether this mid-range CPU can feed the high-end GPU paired with it.

In Doom, the CPU's role appears secondary to the GPU at higher resolutions, yet its 8-core, 16-thread design provides ample headroom for the game's engine. The data shows that at 1080p, the CPU is likely the limiting factor at lower settings, but at 4K, the GPU takes over. The 5700G's 3DMark 16-thread score of 6,629 and max-thread score of 6,627 indicate consistent multi-core performance, which is more than sufficient for a 2016 FPS title. The question is whether its single-thread score of 899 in 3DMark creates a bottleneck at high frame rates, especially when comparing to the GPU's massive compute resources.

Resolution Scaling

The measured FPS data shows a clear pattern of scaling from 1080p to 4K, with the GPU becoming the dominant factor at higher resolutions. At 1080p High, the combo achieves 309.2 FPS, which drops to 220.8 FPS at 1440p (a 28.6% decrease) and further to 118.8 FPS at 4K (a 61.6% decrease from 1080p). This scaling indicates that the RTX 5090 is the primary limiter at 4K, as the CPU's 3DMark scores suggest it can handle the game logic without major bottlenecks.

The Low settings preset shows a similar trend: 343.4 FPS at 1080p, 295.3 FPS at 1440p, and 158.4 FPS at 4K. The drop from 1080p to 1440p is only 14% for Low, compared to 28.6% for High, suggesting that at lower settings, the CPU is more involved in frame generation. However, at 4K, the frame rate nearly halves from 1440p, confirming the GPU's compute resources are the limiting factor. The RTX 5090's 32 GB of GDDR7 memory and 1.79 TB/s bandwidth are not fully taxed at 1080p, but at 4K, the pixel throughput demands become evident.

The data implies that players targeting 4K with this combo will see a significant performance drop, but the frame rates remain playable. The 5700G's 8 cores and 16 threads are sufficient to keep up with the GPU's frame output at 1440p and below, but at 4K, the GPU's raw power is the deciding factor.

How This Combo Ranks

This combination of the AMD Ryzen 7 5700G and NVIDIA GeForce RTX 5090 ranks 63rd out of 1,681 tested combos in Doom. This places it in the top 3.75% of all combinations, indicating strong overall performance. The rank is notable because the CPU is not a top-tier part, yet the GPU's dominance lifts the combo to a high position. The 5700G's 83rd percentile CPU ranking is offset by the RTX 5090's 94th percentile GPU ranking, resulting in a combo that outperforms most systems.

The deltaPct between the CPU and its nearest rivals is minimal, but the GPU's nearest rival, the RTX 5090 D, is only 0.1% faster, while the RTX 5050 Mobile is 0.2% slower. This suggests that the GPU choice is the primary driver of the combo's rank. The fact that the combo ranks 63rd despite the CPU being in the 83rd percentile highlights how GPU-bound Doom is at most settings, especially at higher resolutions.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings average 343.4 FPS, Medium 326.3 FPS, High 309.2 FPS, and Ultra 279.4 FPS. The spread from Low to Ultra is 64 FPS, showing a 18.6% performance penalty for maxing out settings. This indicates that the CPU is not a hard bottleneck, but the GPU's performance scales well with reduced graphical load.

At 2560x1440, the frame rates drop but remain high. Low averages 295.3 FPS, Medium 257.9 FPS, High 220.8 FPS, and Ultra 179 FPS. The drop from Low to Ultra is 116.3 FPS, a 39.4% penalty. The 1440p results show a more pronounced difference between settings, suggesting the GPU is working harder but still has headroom. The 4K results at 3840x2160 show the most significant scaling: Low averages 158.4 FPS, Medium 138.1 FPS, High 118.8 FPS, and Ultra 94.8 FPS. The Ultra preset at 4K drops below 100 FPS, indicating a GPU-heavy workload that taxes the RTX 5090's 104.8 TFLOPS of FP32 compute.

The data shows a consistent pattern: as resolution increases, the frame rate drops proportionally, with the GPU becoming the limiting factor. The 5700G's performance is sufficient to avoid major CPU bottlenecks, as evidenced by the high frame rates at 1080p.

Settings Recommendations

For the best experience, the data suggests using the High preset at 1440p, which averages 220.8 FPS, providing a smooth and visually rich experience. At 1080p, the Ultra preset at 279.4 FPS is playable and offers maximum visual quality without sacrificing frame rate. For 4K, the Medium preset at 138.1 FPS is the highest setting that maintains a playable frame rate, as Ultra drops to 94.8 FPS, which may be borderline for competitive play.

The Low preset at 4K yields 158.4 FPS, which is 67% higher than Ultra, but the visual fidelity loss may not be worth it for most players. The Medium preset at 1440p (257.9 FPS) is also a strong choice, balancing quality and performance. The data implies that the combo is best suited for high-refresh-rate gaming at 1080p and 1440p, while 4K requires sacrificing some settings to maintain high frame rates.

GPU Role

The NVIDIA GeForce RTX 5090 is the dominant component in this combo, with 32 GB of GDDR7 memory on a 512-bit bus, providing 1.79 TB/s of bandwidth. Its base clock of 2017 MHz boosts to 2407 MHz, and it has 21,760 shading units, 680 TMUs, and 176 ROPs. The GPU's FP32 performance is 104.8 TFLOPS, and it achieves a 94th percentile ranking among all GPUs, with an average benchmark score of 84,306. Its nearest rival, the RTX 5090 D, is only 0.1% faster, while the RTX 5050 Mobile is 0.2% slower, showing the 5090's dominance.

In Doom, the GPU's role is clear: it drives frame rates at all resolutions, with the CPU providing support. At 4K Ultra, the 5090 produces 94.8 FPS, which confirms its pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s. The GPU's 170 RT cores and 680 tensor cores are not heavily utilized in this 2016 title, but the raw compute power ensures high frame rates. The RTX 5090's 575 W TDP and 950 W suggested PSU indicate its power draw is significant, but the performance data shows it is the primary driver of this combo's 63rd rank out of 1,681 combos.
