Doom

The AMD Ryzen 5 5600G paired with the AMD Radeon RX 6750 XT delivers a compelling 1080p experience in Doom, with frame rates that remain highly playable even when pushing toward 4K. The measured data reveals a system where the GPU is the primary scaling factor across resolutions, though the CPU’s six Zen 3 cores provide a solid foundation that never becomes a bottleneck in this title.

Resolution Scaling

The frame rate progression from 1080p to 4K shows a clear and predictable decline, with the most dramatic drop occurring between 1440p and 2160p. At 1080p with Low settings, the combo achieves 240 FPS, which represents the ceiling of the measurement range. Moving to Medium at the same resolution yields 208.8 FPS, while High settings produce 179.1 FPS. The Ultra preset at 1080p drops to 142.7 FPS, still comfortably above the 144Hz refresh rate that many competitive gamers target.

At 1440p, the scaling becomes more demanding. Low settings deliver 155.9 FPS, Medium drops to 133.5 FPS, and High produces 115.9 FPS. The Ultra preset at 1440p falls to 93.2 FPS, which represents a 34.7% reduction compared to the 1080p Ultra result. This suggests that while the GPU remains the dominant factor, the CPU’s 12 threads are still keeping pace with the render workload at this resolution.

The jump to 4K reveals the most significant performance cost. High settings at 3840x2160 produce 64.4 FPS, which is a 44.4% decrease from the 1440p High result. Medium at 4K yields 75.1 FPS, while Low achieves 85.8 FPS. The Ultra preset at 4K drops to 51.1 FPS, which is the only measured configuration that falls below the 60 FPS threshold. This pattern indicates that at 4K, the RX 6750 XT’s 12 GB of GDDR6 memory and 432.0 GB/s bandwidth are being taxed heavily, with the GPU’s 2560 shading units working at full capacity.

The data shows that the scaling from 1080p to 1440p is more gradual than from 1440p to 4K. For instance, the High preset loses 63.2 FPS when moving from 1080p to 1440p, but then loses another 51.5 FPS going from 1440p to 4K. This non-linear behavior is typical of a GPU-bound scenario where the pixel throughput requirements at 4K (3840x2160, or approximately 8.3 million pixels) exceed what the card can efficiently process while maintaining high settings.

CPU Role

The AMD Ryzen 5 5600G brings six cores and twelve threads based on the Zen 3 architecture, with a base clock of 3.90 GHz and a boost clock of 4.40 GHz. This Cezanne-generation processor features 16 MB of L3 cache and supports DDR4 memory with dual-channel bandwidth of 51.2 GB/s. In Doom’s benchmark results, the CPU’s role becomes apparent when comparing the 1080p Low result of 240 FPS against the 4K Low result of 85.8 FPS.

The CPU’s single-thread performance, as measured by a Geekbench single-core score of 1933, is sufficient to drive the game’s rendering pipeline at high frame rates. The multi-core score of 7693 indicates that the processor can handle the game’s background threads without becoming a limiting factor. This is reinforced by the 3DMark results, where the 8-thread score of 4694 and max-thread score of 5455 show strong scaling across the available cores.

Doom’s engine benefits from the CPU’s boost clock of 4.40 GHz, particularly at lower resolutions where the GPU has headroom. The 1080p Medium result of 208.8 FPS demonstrates that the processor can feed the GPU with draw calls faster than the graphics card can render them. The Cinebench R23 multi-core score of 16758 places this CPU in the 78th percentile of all processors, with nearest rivals including the Intel Core i7-11600H (0.2% ahead) and Intel Core i7-11800H (0.2% behind), indicating that the 5600G holds its own in compute-heavy tasks.

At 4K, the CPU’s role diminishes as the GPU becomes the bottleneck. The 4K High result of 64.4 FPS versus the 1080p High result of 179.1 FPS shows a 114.7 FPS difference that can be attributed almost entirely to GPU workload. The processor’s 65W TDP and 7 nm process node from TSMC with 10,700 million transistors ensure that thermal throttling is not a concern during extended gaming sessions.

GPU Role

The AMD Radeon RX 6750 XT is the dominant component in this pairing, with its RDNA 2.0 architecture and Navi 22 chip providing 2560 shading units, 160 texture mapping units, and 64 render output units. The GPU’s base clock of 2150 MHz and boost clock of 2600 MHz, along with a game clock of 2495 MHz, allow it to sustain high frame rates across all tested resolutions. The 12 GB of GDDR6 memory on a 192-bit bus delivers 432.0 GB/s of bandwidth, which proves adequate for Doom’s textures at 4K Ultra.

The GPU’s compute capabilities are substantial, with 13.31 TFLOPS of FP32 performance and 40 ray tracing cores. While Doom does not utilize ray tracing, the raw rasterization throughput is what drives the measured results. The PassMark G3D score of 20700 and 3DMark Steel Nomad score of 2548 position this card in the 79th percentile of all GPUs, with nearest rivals including the NVIDIA GeForce RTX 3080 (1.3% ahead) and AMD Radeon 880M (0.9% behind).

The scaling from Low to Ultra settings at each resolution isolates the GPU’s capability. At 1080p, the difference between Low (240 FPS) and Ultra (142.7 FPS) is 97.3 FPS, representing a 40.5% reduction. At 1440p, the same comparison shows a drop from 155.9 FPS to 93.2 FPS, a 40.2% reduction. At 4K, Low produces 85.8 FPS while Ultra drops to 51.1 FPS, a 40.4% reduction. This consistent percentage drop across resolutions indicates that the GPU’s shading units and memory bandwidth scale predictably with the increased workload.

The GPU’s pixel rate of 166.4 GPixel/s and texture rate of 416.0 GTexel/s are the limiting factors at 4K Ultra, where the 51.1 FPS result falls below the 60 FPS target. The memory clock of 2250 MHz (18 Gbps effective) ensures that texture streaming keeps pace with the render output, but the 64 ROPs struggle to fill the 8.3 million pixels at 4K with Ultra-quality effects enabled.

Settings Recommendations

The measured data provides clear guidance for optimal settings based on the target resolution and desired frame rate. At 1080p, the Low preset achieves 240 FPS, which is ideal for high-refresh-rate displays, but the Medium preset at 208.8 FPS offers a better balance of visual fidelity and performance. The High preset at 179.1 FPS remains above 144 Hz, making it the recommended choice for most users at this resolution.

At 1440p, the High preset delivers 115.9 FPS, which is smooth for most monitors, while the Medium preset at 133.5 FPS provides additional headroom. The Ultra preset at 93.2 FPS is still playable but represents a noticeable visual improvement over High with only a 22.7 FPS cost. For 1440p, the data suggests that High is the sweet spot, as it maintains frame rates above 100 FPS while preserving most visual quality settings.

At 4K, the situation changes dramatically. The Low preset at 85.8 FPS is the only configuration that provides a consistently smooth experience. Medium at 75.1 FPS is acceptable for slower-paced sections, but High at 64.4 FPS and Ultra at 51.1 FPS fall below the 60 FPS threshold that most gamers consider minimum for enjoyable gameplay. The recommendation for 4K is to use the Low preset, as the visual difference between Low and Medium at this resolution is less noticeable than the 10.7 FPS performance cost.

The Ultra preset shows diminishing returns across all resolutions. At 1080p, the jump from High to Ultra costs 36.4 FPS, while at 1440p it costs 22.7 FPS, and at 4K it costs 13.3 FPS. These numbers suggest that Ultra provides marginal visual improvements over High, making High the more sensible choice for most users who prioritize frame rate consistency.

How This Combo Ranks

This specific combination of the AMD Ryzen 5 5600G and AMD Radeon RX 6750 XT ranks 842nd out of 1681 tested combos in Doom, placing it in the upper half of all configurations. This ranking reflects the balance between the CPU’s 78th percentile performance and the GPU’s 79th percentile performance, with the system operating as expected for its component tier.

The combo ranking of 842 out of 1681 indicates that approximately half of all tested configurations outperform this pairing, while the other half fall behind. Given that the CPU and GPU each sit near the 79th percentile of their respective categories, the combined result aligns with what the individual component benchmarks would predict. The nearest CPU rivals—the Intel Core i7-11600H and Intel Core i7-11800H—show delta percentages of 0.2% and -0.2% respectively, confirming that the 5600G is well-matched with its direct competitors.

The GPU’s nearest rivals reinforce the card’s positioning. The NVIDIA GeForce RTX 3080 is 1.3% ahead in average benchmark score, while the AMD Radeon 880M is 0.9% behind. These small deltas suggest that the RX 6750 XT delivers performance that is highly competitive within its class, and the combination with the 5600G does not introduce any significant bottleneck that would push the combo rank lower than expected.

In practical terms, the 842nd rank out of 1681 combos means that this system is positioned for 1080p and 1440p gaming with high settings, with 4K achievable at reduced settings. The measured FPS data confirms that the combo delivers excellent performance in Doom, with the GPU being the primary determinant of frame rates at higher resolutions and the CPU providing sufficient throughput to avoid limiting the graphics card at any resolution tested.
