Doom

The AMD Ryzen 5 5600G paired with the NVIDIA GeForce RTX 4080 SUPER delivers a formidable 1080p experience in Doom, with frame rates that push well past high-refresh-rate display thresholds. However, the data reveals a less straightforward picture as resolution scales, with the CPU’s architectural limits becoming increasingly apparent at lower settings. This combination ranks 141st out of 1681 tested combos, placing it in the top 8.4% of all configurations, a strong showing that underscores the GPU’s dominance in this pairing.

Resolution Scaling

The measured FPS data shows a clear and expected decline as resolution increases, but the shape of that decline tells a significant story about which component is driving performance. At 1080p with Low settings, the combo achieves 335.4 FPS, dropping to 291.7 FPS at High settings—a relatively modest 13% reduction. This suggests that even at Low settings, the game is not fully CPU-bound, as the gap between Low and High is far smaller than the gap between resolutions.

Moving to 1440p, the frame rates remain exceptionally high: 257 FPS at Low, 223.1 FPS at Medium, 188.4 FPS at High, and 154.5 FPS at Ultra. The scaling from 1080p to 1440p at High settings shows a drop from 291.7 FPS to 188.4 FPS, a 35% reduction. This significant decline indicates that the GPU is beginning to take on more load, but the RTX 4080 SUPER’s massive compute resources are still far from saturated, as even the 1440p Ultra figure of 154.5 FPS is well above the 144Hz refresh rate common on high-end monitors.

At 4K, the picture changes dramatically. High settings produce 106.1 FPS, Medium delivers 125.1 FPS, and Ultra drops to 85.6 FPS. The most telling data point is the Low setting at 4K: 137.9 FPS. This is only 16% lower than the 1440p Low score of 257 FPS, but the jump from 1080p Low (335.4 FPS) to 1440p Low (257 FPS) is a 23% decrease. The fact that 4K Low (137.9 FPS) is closer to 4K Ultra (85.6 FPS) than to 1080p Low suggests that the Ryzen 5 5600G’s single-thread performance is becoming the limiting factor at higher resolutions when graphical load is low.

The scaling pattern indicates that the RTX 4080 SUPER is never the bottleneck at 1080p or 1440p, even at Ultra settings. The CPU, with its 6 cores and 12 threads, is likely holding back the GPU’s potential at these resolutions. The 4K results, particularly the 85.6 FPS at Ultra, show that the GPU is finally being pushed, but the relatively small gap between 4K Low and 4K High (137.9 vs. 106.1 FPS) suggests the CPU’s IPC limits are still influencing the floor.

CPU Role

The AMD Ryzen 5 5600G is a 6-core, 12-thread processor based on the Zen 3 architecture, running on the Cezanne codename. Its base clock of 3.90 GHz and boost clock of 4.40 GHz are respectable for a 5000-series part, but the data suggests these clocks are not sufficient to fully feed the RTX 4080 SUPER in Doom’s fast-paced engine. The CPU’s 3DMark single-thread score of 872 and Cinebench R23 single-core score of 2365 place it in the 78th percentile of all CPUs, indicating solid but not exceptional single-thread performance.

Looking at the measured results, the CPU’s influence is most visible in the 1080p Low scenario (335.4 FPS). This figure is likely approaching the CPU’s maximum frame generation capability, as the difference between Low and Medium at 1080p (335.4 vs. 317.3 FPS) is only 5.4%, while the difference between Medium and High (317.3 vs. 291.7 FPS) is 8.1%. The relatively flat scaling across settings at 1080p is a classic sign of CPU limitation, as the GPU has ample headroom to render more frames if the CPU could provide them.

The CPU’s 16 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth are adequate for gaming, but the processor’s PCIe Gen 3 interface—rather than Gen 4—may slightly constrain data transfer to the GPU, though this is unlikely to be a major factor in Doom’s results. The 5600G’s integrated Radeon Vega 7 GPU is irrelevant here, as the discrete RTX 4080 SUPER handles all rendering.

The nearestRivals data shows the 5600G’s average benchmark score of 19983 is nearly identical to the Intel Core i7-11600H (19949, deltaPct 0.2), Intel Core i7-11800H (20024, deltaPct -0.2), and AMD EPYC 7713P (20024, deltaPct -0.2). This places the 5600G in a crowded field of mid-range processors, all within 0.3% of each other. The fact that this CPU is paired with a top-tier GPU like the RTX 4080 SUPER creates an imbalance that is evident in the scaling data.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is the clear performance driver in this combo. With 16 GB of GDDR6X memory on a 256-bit bus, delivering 736.3 GB/s of bandwidth, the GPU has ample resources for Doom’s 2016-era engine. Its boost clock of 2550 MHz and 10240 shading units provide massive compute throughput, reflected in its Passmark G3D score of 34245 and 3DMark Steel Nomad DX12 score of 6600. The GPU sits in the 88th percentile of all GPUs, with an average benchmark score of 53610.

The GPU’s influence is most apparent at 4K Ultra, where the 85.6 FPS result shows the card being pushed to its limits. The jump from 4K High (106.1 FPS) to 4K Ultra (85.6 FPS) is a 19.3% drop, which is substantial and indicates that the GPU is now the primary bottleneck. Similarly, the 4K Medium result of 125.1 FPS drops to 106.1 FPS at High, a 15.2% reduction, showing that the GPU is scaling with graphical fidelity as expected.

The RTX 4080 SUPER’s nearestRivals include the AMD Radeon RX 6900 XT (53489, deltaPct 0.2), AMD Radeon Pro W6600M (53414, deltaPct 0.4), AMD Radeon RX 7700S (52505, deltaPct 2.1), and NVIDIA GeForce RTX 5070 Ti (52086, deltaPct 2.9). The 4080 SUPER’s average score of 53610 leads this group, but the margin over the RX 6900 XT is a razor-thin 0.2%. This tells us that while the 4080 SUPER is a top-tier card, it is not head-and-shoulders above its closest competitors in raw compute, making the CPU pairing even more critical.

In Doom specifically, the GPU’s 16 GB VRAM is more than sufficient, as the game’s textures are modest by modern standards. The 736.3 GB/s bandwidth ensures that even at 4K Ultra, texture streaming is unlikely to cause stutters, which is reflected in the consistent FPS numbers across all settings.

FAQ

Q: Does the CPU’s 6-core/12-thread configuration limit performance?

A: Yes, the 6-core/12-thread design, while scoring in the 78th percentile of all CPUs, shows signs of limitation in the 1080p results where FPS does not scale appreciably with settings.

How This Combo Ranks

The AMD Ryzen 5 5600G + NVIDIA GeForce RTX 4080 SUPER combination achieves a rank of 141 out of 1681 tested combos in Doom. This places it in the 91.6th percentile of all configurations, a strong result that reflects the GPU’s immense power. However, the ranking also highlights the CPU’s relative weakness: the 5600G’s 78th percentile CPU score is the limiting factor, preventing this combo from breaking into the top 100.

The data shows that this combo is capable of exceptional frame rates at 1080p and 1440p, with even 4K Ultra remaining playable at 85.6 FPS. The primary takeaway is that the RTX 4080 SUPER is significantly overqualified for this CPU pairing, as evidenced by the CPU-bound behavior at lower resolutions. At 1080p, the difference between Low and Ultra settings is only 28.6% (335.4 vs. 239.6 FPS), which is far less than the GPU’s capability would suggest. In contrast, at 4K, the difference between Low and Ultra is 61% (137.9 vs. 85.6 FPS), showing the GPU beginning to assert its dominance.

The rank of 141 is respectable but not elite, and it is clear that a more powerful CPU would allow this GPU to achieve higher rankings. The 5600G’s nearest CPU rivals—the i7-11600H, i7-11800H, and EPYC 7713P—all have nearly identical average scores, indicating that no mid-range processor would meaningfully change this combo’s position. The bottleneck is the CPU’s single-thread performance, which caps frame generation at around 335 FPS in Doom’s engine. For gamers targeting 144Hz or 240Hz displays at 1080p, this combo delivers, but it leaves performance on the table compared to what the RTX 4080 SUPER could achieve with a higher-tier CPU.
