Doom

This combo pairs the AMD Ryzen 5 5600G with the AMD Radeon RX 7900 XTX, and in Doom it produces a broad range of frame rates that depend heavily on both resolution and quality preset. The measured data shows that this is a pairing capable of extreme performance, but the balance between the two components shifts dramatically depending on the settings chosen.

How This Combo Ranks

The combination of the Ryzen 5 5600G and the Radeon RX 7900 XTX ranks 267th out of 1681 tested combos for this game. That places it in the top 16% of all tested configurations, a strong showing that puts it well ahead of the median system. However, the ranking is not solely a product of the GPU's power; the CPU plays a significant role in determining whether the system can reach its full potential. The data suggests that while the GPU is capable of very high frame rates, the processor can become a limiting factor at lower resolutions where the rendering load is lighter. The overall rank reflects a system that is fast, but the performance ceiling is influenced by the CPU's capabilities as much as the GPU's raw throughput.

GPU Role

The AMD Radeon RX 7900 XTX is the dominant component in this pairing, and its specifications show why it is capable of such high frame rates. The GPU features 24 GB of GDDR6 memory on a 384-bit bus, delivering 960.0 GB/s of bandwidth. This large memory pool and high bandwidth are critical for handling the textures and geometry in Doom at high resolutions without stuttering. The GPU's clock speeds are also substantial: a base clock of 1929 MHz and a boost clock of 2498 MHz allow it to push through the game's demanding scenes. The game clock of 2365 MHz is a more realistic indicator of sustained performance during gameplay, and the data confirms that this translates to high average FPS across all settings.

The GPU's role becomes more pronounced as resolution increases. At 3840x2160 (4K), the difference between presets is significant, showing that the GPU is heavily loaded. The GPU is not just fast; it is also well-positioned relative to its peers. Benchmark results show it outperforms the NVIDIA GeForce RTX 4070 Ti by 2% in average score, and it sits close to the NVIDIA GeForce RTX 4090 Mobile, which is 0.8% behind. This places the RX 7900 XTX in a performance tier that is clearly designed for high-end gaming, making it the primary driver of the high frame rates observed in this test.

Settings Recommendations

The measured FPS data provides clear guidance on which settings preset offers the best experience. At 2560x1440, the High preset delivers 172.7 FPS, which is well above the threshold for smooth gameplay on most high-refresh-rate monitors. The Ultra preset at this resolution produces 141.9 FPS, still excellent, but the drop from High is noticeable. The Medium preset at 204.7 FPS and Low at 234.5 FPS are faster, but they sacrifice visual quality for marginal gains that are unlikely to be perceptible on standard displays.

At 1920x1080, the situation is similar. The High preset reaches 270.6 FPS, which is far beyond what most displays can show. The Ultra preset at 217.1 FPS is still incredibly fast, and the difference between High and Ultra is less impactful than at higher resolutions. However, the best balance of visual fidelity and performance is found at 2560x1440 with the High preset. This setting provides a substantial frame rate cushion above 144 FPS while maintaining the graphical details that make the game look good. At 4K, the High preset at 94.1 FPS is playable, but the Ultra preset at 74.3 FPS may be too demanding for those who prefer a locked 60 FPS or higher. The data shows that High is the sweet spot for this combo, offering the best combination of smoothness and image quality without pushing the GPU to its limits unnecessarily.

FAQ

*Q: Can this combo run Doom at 4K with high settings?*

A: Yes. The measured data shows an average of 94.1 FPS at 3840x2160 with High settings, which is smooth for most gaming scenarios.

Q: What is the fastest preset at 1080p?

A: The Low preset produces the highest average FPS at 1920x1080, reaching 332.9 FPS. However, this comes with significant visual compromises.

Q: Is there a big performance difference between High and Ultra at 1440p?

A: Yes. At 2560x1440, High delivers 172.7 FPS while Ultra drops to 141.9 FPS, a difference of about 30 FPS. This is a meaningful gap that favors High for competitive play.

Q: How does the CPU affect performance at lower resolutions?

A: At lower resolutions, the GPU is less stressed, and the CPU becomes more of a bottleneck. The data shows that at 1080p, the frame rates are extremely high, but the scaling from Medium to Low suggests the CPU is limiting the maximum possible output.

Q: Is the RX 7900 XTX a good match for the Ryzen 5 5600G?

A: The data shows it is a capable pairing, but the CPU may hold back the GPU at lower resolutions. At higher resolutions like 4K, the GPU is the primary driver, and the combo performs well.

Q: What is the recommended resolution for this combo?

A: Based on the data, 2560x1440 with High settings is the best choice, as it provides 172.7 FPS without taxing the system unnecessarily. This offers a good balance between image quality and performance headroom.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals how the workload shifts between the CPU and GPU. At 1920x1080 with High settings, the combo achieves 270.6 FPS. Moving to 2560x1440 drops this to 172.7 FPS, a reduction of about 36%. At 3840x2160, the frame rate falls further to 94.1 FPS, which is a 65% drop from the 1080p result. This scaling pattern is typical of a system where the GPU becomes increasingly dominant as resolution rises.

The data indicates that at 1080p, the CPU is likely the limiting factor. The difference between the Low preset (332.9 FPS) and the High preset (270.6 FPS) at 1080p is relatively small compared to the GPU's potential, suggesting that the Ryzen 5 5600G cannot feed the RX 7900 XTX fast enough to saturate it. As resolution increases, the GPU's workload grows, and the frame rates begin to scale more predictably with the GPU's capabilities. At 4K, the GPU is clearly the limiting component, as the frame rates align more closely with the GPU's raw performance relative to its rivals. The drop from 1440p to 4K is substantial, which is expected given the fourfold increase in pixel count, but the system still maintains playable frame rates even on Ultra settings at 4K.

CPU Role

The AMD Ryzen 5 5600G is a 6-core, 12-thread processor based on the Zen 3 architecture, with a base clock of 3.90 GHz and a boost clock of 4.40 GHz. It has 16 MB of L3 cache and supports dual-channel DDR4 memory with a bandwidth of 51.2 GB/s. These specifications are modest compared to the GPU, and the benchmark results reflect that. In multi-threaded tests, the CPU scores 16,758 points in Cinebench R23, which places it in the 78th percentile of all CPUs. Its nearest rivals include the Intel Core i7-11600H, which is 0.2% faster, and the Intel Core i7-11800H, which is 0.2% slower. This puts the 5600G in a solid mid-range position for CPU performance.

In Doom, the CPU's role is most evident at lower resolutions. The game is well-optimized and can run at very high frame rates, but the CPU's single-thread performance becomes a bottleneck when the GPU is not fully utilized. The single-core score of 2,365 in Cinebench R23 is respectable but not top-tier, which aligns with the observed scaling at 1080p. At higher resolutions, the CPU's impact diminishes, and the GPU takes over as the primary performance driver. The data shows that the combo performs best when the resolution is high enough to keep the GPU busy, allowing the CPU to keep up with the frame pacing. For users who primarily play at 1080p, the CPU may hold back the GPU, but at 1440p and 4K, the balance is much better.
