Doom

The AMD Ryzen 5 5600G paired with the AMD Radeon RX 7800 XT delivers a strong performance profile in Doom, placing the combination in the 63rd percentile of all tested configurations. With a rank of 628 out of 1681 combos, this pairing sits comfortably in the upper-midrange tier of the database, indicating that it handles the game’s demands without significant bottlenecks. The data shows a system that is well-balanced for high-refresh-rate 1440p play and capable of maintaining playable frame rates at 4K, though the CPU begins to show its limitations as resolution drops and frame rates climb.

How This Combo Ranks

The combo’s rank of 628 out of 1681 tested combinations places it in the upper third of all systems in the database. This percentile position reflects a configuration that is substantially faster than a typical midrange build, yet it does not crack the top tier where flagship CPUs and GPUs dominate. The ranking is driven primarily by the GPU’s strong raw throughput, as the RX 7800 XT sits in the 76th percentile among all GPUs, while the Ryzen 5 5600G’s 78th percentile CPU standing is a close match. The synergy between these two components is evident: neither part drags the other down to a degree that would push the combo into a lower percentile bracket.

When compared to the nearest rival processors, the Ryzen 5 5600G’s average benchmark score of 19983 is nearly identical to the Intel Core i7-11600H’s 19949, a delta of just 0.2%. Similarly, it trails the Intel Core i7-11800H and AMD EPYC 7713P by only 0.2%, both of which score 20024. This tight clustering indicates that the CPU is not a differentiator at this performance level; the GPU is responsible for pushing this combo up the ranks. In Doom specifically, the measured FPS at 1080p and 1440p suggest that the system is often GPU-bound, which means the combo’s overall rank is more reflective of the graphics card’s capabilities than the processor’s.

GPU Role

The AMD Radeon RX 7800 XT is the dominant component in this pairing, and its specifications explain why. With 16 GB of GDDR6 memory on a 256-bit bus, the card provides 624.1 GB/s of bandwidth, which is ample for Doom’s texture-heavy environments even at 4K. The GPU’s boost clock of 2430 MHz and game clock of 2124 MHz are derived from the RDNA 3.0 architecture, and its 3840 shading units deliver 37.32 TFLOPS of FP32 compute. These figures translate directly to the measured frame rates: at 4K Ultra settings, the card still manages an average of 61.8 FPS, which is only possible with this level of raw throughput.

The GPU’s role becomes clearer when examining the scaling from 1080p to 4K. At 1080p Low, the system hits 282.7 FPS, but this number drops to 96.9 FPS at 4K Low, a reduction of 65.7%. This steep decline indicates that the GPU is the primary limiting factor at higher resolutions, as the CPU’s workload remains relatively constant while the pixel count quadruples. The RX 7800 XT’s 96 ROPs and 240 TMUs handle the rasterization load efficiently, but the data shows that even this powerful card cannot maintain triple-digit frame rates at 4K with Ultra settings. The VRAM capacity, however, is never a concern; 16 GB is more than sufficient for Doom, and the benchmarks show no signs of memory-related stuttering or frame drops.

Resolution Scaling

The measured FPS data reveals a predictable scaling pattern as resolution increases. At 1080p with High settings, the combo produces 208.6 FPS; at 1440p High, it drops to 134.9 FPS, a 35.3% reduction; and at 4K High, it falls to 72.5 FPS, another 46.3% drop from 1440p. This progressive decline is characteristic of a GPU-bound scenario, where the CPU has enough headroom to feed the graphics card at lower resolutions but the GPU’s fill rate becomes the bottleneck as pixel density increases.

The Low settings preset provides the clearest view of the CPU’s influence. At 1080p Low, the system reaches 282.7 FPS, which is a very high frame rate that suggests the processor is still keeping pace. However, the jump from 1080p Low to 1440p Low shows a 35.8% drop to 181.4 FPS, and then a further 46.6% decline to 96.9 FPS at 4K Low. The fact that the frame rate at 4K Low (96.9 FPS) is higher than at 4K Ultra (61.8 FPS) confirms that the GPU is the limiting factor; reducing the settings lowers the GPU’s workload, allowing the CPU to feed frames faster. If the CPU were the bottleneck, the frame rate would remain flat across different settings at the same resolution, which is not the case here.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings produce an average of 282.7 FPS, Medium drops to 246.4 FPS, High reaches 208.6 FPS, and Ultra bottoms out at 169.3 FPS. These numbers indicate that the system is well-suited for competitive play on high-refresh-rate monitors, as even the most demanding preset at this resolution stays well above the 144 Hz threshold.

Moving to 2560x1440, the frame rates remain strong but show a more pronounced impact from settings. Low settings yield 181.4 FPS, which is still exceptionally smooth. Medium settings produce 159.6 FPS, High drops to 134.9 FPS, and Ultra falls to 107.5 FPS. The 40.7% reduction from Low to Ultra at 1440p is steeper than the 40.1% reduction at 1080p, indicating that the GPU is working harder as the resolution increases, but the combo still offers a playable experience at all settings.

At 3840x2160, the system crosses into less comfortable territory. Low settings average 96.9 FPS, which is playable but not ideal for high-refresh displays. Medium settings drop to 85.7 FPS, High to 72.5 FPS, and Ultra to 61.8 FPS. The latter figure is right at the edge of what most players would consider acceptable for a smooth experience, though it does not reach the 60 FPS floor. The data shows a clear linear relationship between settings and frame rate at 4K, with each step down in quality providing roughly a 10-15 FPS improvement.

CPU Role

The AMD Ryzen 5 5600G, with its 6 cores and 12 threads, is a capable processor for Doom, but its role in this combo is secondary to the GPU. The CPU’s base clock of 3.90 GHz and boost clock of 4.40 GHz, combined with its 16 MB of L3 cache, provide enough single-thread performance to avoid bottlenecking the RX 7800 XT at most settings. The benchmark results support this: the CPU’s single-thread score of 2365 in Cinebench R23 is respectable, and its multicore score of 16758 indicates that it has sufficient headroom for the game’s threading demands.

However, the CPU’s limitations become apparent at 1080p with Low settings, where the frame rate reaches 282.7 FPS. This is a very high number, but it is also close to the point where the Ryzen 5 5600G’s single-thread performance would start to cap the GPU’s output. The data does not show a complete plateau, but the fact that the 1080p Low frame rate is only 37.4% higher than the 1440p Low frame rate, despite the 1440p resolution having 78% more pixels, suggests that the CPU is beginning to exert some influence at the lowest resolution. If the GPU were fully responsible for the scaling, the 1080p frame rate would be significantly higher relative to 1440p.

In terms of its position among rival CPUs, the Ryzen 5 5600G’s average benchmark score of 19983 is effectively tied with the Intel Core i7-11600H (19949, +0.2%), the Intel Core i7-11800H (20024, -0.2%), and the AMD EPYC 7713P (20024, -0.2%). This clustering means that swapping the 5600G for any of these processors would not meaningfully change the Doom results, as the GPU would remain the bottleneck in most scenarios. The CPU’s 65W TDP and 7nm process node are not directly relevant to gaming performance, but they do indicate that this is a power-efficient part that does not require exotic cooling solutions. In Doom, the Ryzen 5 5600G provides a stable foundation, but the RX 7800 XT is clearly the component that determines the combo’s ranking and overall playability.
