Doom

The AMD Ryzen 5 5600G paired with the AMD Radeon RX 6800 XT delivers a dominant performance profile in Doom, with frame rates that scale predictably across resolutions and settings. The data reveals a system where the GPU is the primary driver at higher resolutions, while the CPU’s six Zen 3 cores prove more than sufficient to feed the RDNA 2 architecture at 1080p.

Resolution Scaling

The measured FPS data shows a steep and consistent drop as resolution increases, which is the classic signature of a GPU-bound workload. At 1920x1080 with Low settings, the combo produces 291.4 FPS average. Moving to 2560x1440 Low drops that figure to 185.5 FPS, a reduction of approximately 36%. At 3840x2160 Low, the average falls further to 104.8 FPS, which is another 43% decrease from the 1440p result. This scaling pattern indicates that the RX 6800 XT is the limiting component at every step, with the CPU holding little influence over the frame rate as pixel count climbs.

The gap between Low and Ultra settings widens with resolution, highlighting the GPU’s workload. At 1080p, the difference between Low (291.4 FPS) and Ultra (175.5 FPS) is 115.9 FPS. At 1440p, that spread shrinks to 74.4 FPS (185.5 vs 111.1). At 4K, the spread narrows further to 45.5 FPS (104.8 vs 59.3). This trend shows that as resolution rises, the pixel fill rate dominates, and the settings-based performance penalty becomes relatively smaller in absolute terms. The 4K Ultra result of 59.3 FPS is the only sub-60 FPS figure in the entire dataset, suggesting that even the top preset just barely fails to maintain a smooth experience at the highest pixel count.

How This Combo Ranks

In the broader database of tested combinations, this pairing sits at rank 593 out of 1681 combos for Doom. That places it in the upper third of all configurations, though not at the very top. The rank reflects a system that is clearly capable of high refresh-rate play at mainstream resolutions but is not optimized for absolute maximum 4K performance. Given the GPU’s percentileVsAllGpus of 87 and the CPU’s percentileVsAllCpus of 78, the combo’s mid-tier rank makes sense: it is a strong pairing, but the CPU’s relatively lower standing in synthetic benchmarks (compared to the GPU) likely prevents it from climbing higher in a game that can occasionally stress the processor at very low resolutions.

The data indicates that the combo’s rank is not limited by the GPU’s raw power. The RX 6800 XT outperforms several close rivals in average benchmark score, including the Intel Arc A550M (by 0.5%) and the NVIDIA CMP 50HX (by 1.9%), and it trails only the NVIDIA RTX A1000 (by 1.7%) among its nearest competitors. The CPU, meanwhile, is within 0.2% of the Intel Core i7-11600H and 0.3% of the AMD Ryzen Threadripper PRO 5995WX in average score, showing that it is a competent mid-range part. The combination of a high-tier GPU with a mid-tier CPU produces a balanced system that ranks well but not exceptionally.

CPU Role

The AMD Ryzen 5 5600G is a 6-core, 12-thread processor built on the Zen 3 architecture, with a base clock of 3.90 GHz and a boost clock of 4.40 GHz. Its 16 MB of L3 cache and DDR4-3200 memory support (yielding 51.2 GB/s bandwidth) are adequate for feeding a modern GPU in a fast-paced FPS like Doom. The CPU’s synthetic benchmark results show strong single-thread performance, with a Cinebench R23 single-core score of 2365 and a Geekbench single-core score of 1933. These numbers are crucial for a game engine that often relies on a few primary threads for game logic and draw calls.

At 1080p, the CPU’s role becomes more apparent. The jump from High (216.3 FPS) to Low (291.4 FPS) at 1080p is substantial, and the fact that the frame rate exceeds 200 FPS at all settings except Ultra indicates that the 5600G is not bottlenecking the GPU in this resolution. The multi-threaded scores, such as Cinebench R23 multi-core at 16758, suggest that the 12 threads can handle the game’s background tasks without issue. However, the CPU’s average benchmark score of 19983 places it just 0.2% behind the Intel Core i7-11800H and 0.2% ahead of the Intel Core i7-11600H, which are mobile parts, indicating that this desktop chip is not a top-tier performer in absolute terms. For Doom, that is sufficient; the data shows no scenario where the CPU becomes the limiting factor, as the FPS scales almost entirely with resolution and settings rather than showing a plateau at high frame rates.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across three resolutions and four settings levels. At 1920x1080, the combo delivers 291.4 FPS on Low, 255.2 FPS on Medium, 216.3 FPS on High, and 175.5 FPS on Ultra. These figures are all well above 144 Hz, making the setup ideal for high-refresh-rate monitors. The 1080p results show that the GPU is not fully taxed until Ultra settings, where the frame rate still remains exceptionally high.

Moving to 2560x1440, the averages are 185.5 FPS on Low, 162.7 FPS on Medium, 137.9 FPS on High, and 111.1 FPS on Ultra. Every preset at this resolution clears the 100 FPS threshold, ensuring smooth gameplay on 1440p panels with high refresh rates. The scaling from Low to Ultra at 1440p is a 74.4 FPS drop, which is proportionally similar to the 1080p scaling, though the absolute numbers are lower.

At 3840x2160, the performance becomes more demanding. Low settings yield 104.8 FPS, Medium produces 88 FPS, High drops to 77.8 FPS, and Ultra falls to 59.3 FPS. While the first three presets maintain playable frame rates, the Ultra preset barely misses the 60 FPS mark, which could be a concern for users with 4K displays who prefer maximum visual fidelity. The data shows a clear trend: this combo is excellent for 1080p and 1440p gaming, and it can handle 4K with reduced settings, but it is not a native 4K Ultra machine in Doom.

GPU Role

The AMD Radeon RX 6800 XT is the dominant component in this pairing, and its specifications explain the measured results. It features 16 GB of GDDR6 memory on a 256-bit bus, providing 512.0 GB/s of bandwidth. This memory capacity ensures that even at 4K Ultra, the GPU does not run out of VRAM, as evidenced by the 59.3 FPS result rather than a stutter-induced crash. The GPU’s 4608 shading units, 288 TMUs, and 128 ROPs deliver a pixel rate of 288.0 GPixel/s and a texture rate of 648.0 GTexel/s, which are high enough to sustain the frame rates seen in the data.

The clock speeds are also a factor. The base clock is 1825 MHz, the game clock is 2015 MHz, and the boost clock reaches 2250 MHz, with memory running at 2000 MHz (16 Gbps effective). These frequencies, combined with the RDNA 2.0 architecture, produce a measured FP32 performance of 20.74 TFLOPS. In Doom, which is a well-optimized Vulkan and DirectX 12 title, this raw compute power translates directly into the high frame rates observed. The GPU’s percentileVsAllGpus of 87 indicates it ranks in the top 13% of all GPUs, and its average benchmark score of 49982 places it ahead of the Intel Arc A550M by 0.5% and the NVIDIA CMP 50HX by 1.9%, while sitting just 1.7% behind the NVIDIA RTX A1000.

The GPU’s role is most evident in the resolution scaling. The 4K Ultra result of 59.3 FPS is only 26% lower than the 4K High result of 77.8 FPS, showing that the GPU is still the primary bottleneck at that resolution, but the settings overhead is relatively small. Meanwhile, the 1080p Low result of 291.4 FPS approaches the refresh rate limits of most monitors, indicating that the GPU has ample headroom even when the CPU is pushed harder. This combination of high memory bandwidth, substantial shading resources, and aggressive clock speeds makes the RX 6800 XT the clear performance driver in this setup, with the Ryzen 5 5600G acting as a capable but secondary partner.
