Doom

The AMD Ryzen 5 4600G paired with the NVIDIA GeForce RTX 3080 delivers a robust 1080p experience in Doom, but the data reveals a system where the CPU begins to assert its influence at lower resolutions while the GPU firmly dictates performance scaling at 4K. This combination lands at rank 540 out of 1681 tested combos for this title, indicating a solid mid-to-upper tier position that excels at high refresh rate play.

Resolution Scaling

The measured FPS data shows a clear and predictable decline as resolution increases, but the rate of that decline tells a compelling story about system balance. At High settings, the average frame rate drops from 219 FPS at 1920x1080 to 144.7 FPS at 2560x1440, a reduction of 74.3 FPS. Moving further to 3840x2160, the average falls to 78.9 FPS, which is a 65.8 FPS drop from the 1440p figure. The transition from 1080p to 4K at High settings represents a 64% reduction in average FPS, a substantial hit that points squarely at the GPU as the primary limiter at higher resolutions.

The scaling pattern across settings reinforces this GPU-bound conclusion. At Low settings, the system produces 278.1 FPS at 1080p, 197.4 FPS at 1440p, and 103.3 FPS at 4K. The percentage drops are steeper at lower presets, suggesting that when the GPU has less work to do, the CPU becomes more relevant. However, even at 4K Low, the system maintains over 100 FPS, demonstrating that the RTX 3080 retains significant headroom even when the resolution burden is at its maximum.

Ultra settings present the most demanding scenario, with averages of 180.2 FPS at 1080p, 119.2 FPS at 1440p, and only 63.7 FPS at 4K. The Ultra preset at 4K is the only configuration in the entire dataset that falls below the 60 FPS threshold, indicating that this is the point where the combination of the RTX 3080's 10 GB VRAM and raw compute power reaches its practical limit for smooth play. The data suggests that for competitive play at high refresh rates, 1080p and 1440p are the sweet spots, while 4K is viable only at reduced settings.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture, codenamed Renoir, built on a 7 nm process. Its base clock of 3.70 GHz and boost clock of 4.20 GHz provide the foundation for its performance. In synthetic benchmarks, the chip scores 13593 in Cinebench R23 multicore and 1919 in single-core, with a Passmark multithread score of 15992 and a single-thread score of 2653. These figures place the processor at the 75th percentile among all CPUs tested.

The nearest rival data shows a tight cluster around this processor. The AMD Ryzen 3 PRO 5355GE matches the 4600G's average score at 17482 with a 0% delta, while the Intel Core i5-12450H sits 0.1% higher at 17475. The Intel Core i3-14100T comes in at 17636 with a -0.8% delta, and the Core i3-13100F reaches 17665 with a -1% delta. This positioning suggests the 4600G is competitively placed in the mid-range segment, offering balanced multi-threaded performance.

In Doom, the CPU's role becomes apparent in the gap between Low and Ultra settings at 1080p. At Low settings, the system achieves 278.1 FPS, but at Ultra this drops to 180.2 FPS. The 97.9 FPS difference indicates that even at 1080p, the GPU is still the dominant factor, yet the CPU's 12 threads and 8 MB of shared L3 cache are sufficient to feed the RTX 3080 without becoming a severe bottleneck. The 3DMark scores tell a similar story, with 4-thread performance at 2732 and 8-thread at 4138, showing scalable thread utilization that aligns with modern game engines.

GPU Role

The NVIDIA GeForce RTX 3080 is built on the Ampere architecture using an 8 nm process from Samsung, featuring the GA102 chip with 28,300 million transistors on a 628 mm² die. It operates with a base clock of 1440 MHz and a boost clock of 1710 MHz, paired with 10 GB of GDDR6X memory on a 320-bit bus, delivering 760.3 GB/s of bandwidth. The GPU's 8704 shading units, 272 TMUs, and 96 ROPs provide substantial raw throughput, with FP32 performance rated at 29.77 TFLOPS.

The RTX 3080's benchmark profile places it at the 80th percentile among all GPUs, with an average score of 35787. Its nearest rivals include the AMD Radeon Pro Duo at 35860 with a -0.2% delta, the AMD Radeon 880M at 35646 with a 0.4% delta, and the AMD Radeon RX 7900 GRE at 36101 with a -0.9% delta. This indicates the 3080 sits comfortably in a competitive tier, slightly outperforming the integrated Radeon 880M while trailing the RX 7900 GRE by less than 1%.

In Doom, the GPU's 10 GB VRAM capacity proves adequate across most configurations, but the 4K Ultra result of 63.7 FPS suggests memory bandwidth and capacity limits are being approached. The 760.3 GB/s bandwidth is a key asset, allowing the GPU to maintain high frame rates at 1440p where the data shows 170.2 FPS at Medium and 144.7 FPS at High. The pixel rate of 164.2 GPixel/s and texture rate of 465.1 GTexel/s are well-suited to Doom's fast-paced rendering demands, evidenced by the consistent frame delivery across settings.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest performance across all presets. Low settings produce an average of 278.1 FPS, Medium reaches 264.3 FPS, and High achieves 219 FPS. Ultra at 1080p yields 180.2 FPS. The spread from Low to Ultra is 97.9 FPS, representing a 35% reduction in frame rate, which is substantial but still leaves all configurations comfortably above 144 Hz for high-refresh displays.

Moving to 2560x1440, the averages shift to 197.4 FPS at Low, 170.2 FPS at Medium, 144.7 FPS at High, and 119.2 FPS at Ultra. The Low-to-Ultra delta here is 78.2 FPS, a 40% drop. Notably, even at Ultra, the 1440p result exceeds 119 FPS, ensuring a smooth experience on most high-refresh monitors. The gap between Medium and High at this resolution is 25.5 FPS, indicating that the High preset offers a reasonable visual upgrade without a catastrophic performance penalty.

At 3840x2160, the data shows 103.3 FPS at Low, 92.1 FPS at Medium, 78.9 FPS at High, and 63.7 FPS at Ultra. The Low-to-Ultra spread narrows to 39.6 FPS, representing a 38% reduction. This tighter range at 4K indicates that the GPU is saturating its capabilities across all presets, with the difference between settings becoming less impactful on overall frame rate. The High preset at 4K still delivers 78.9 FPS, which is playable, but the Ultra preset dips below 64 FPS, pushing the system toward the edge of its performance envelope.

The data reveals that the most efficient operating point for this combination is 1440p High, where the 144.7 FPS average balances visual fidelity with frame rate. At 1080p, the system is clearly CPU-limited at lower presets, while at 4K, the GPU becomes the unequivocal bottleneck, particularly at Ultra settings.
