Doom

This CPU/GPU pairing delivers a surprisingly balanced experience in Doom, but the balance shifts dramatically depending on resolution and quality preset. At 1080p Low, the system pushes 229.2 FPS, yet that number craters to 49 FPS at 4K Ultra. The measured data reveals a system that is capable of high-refresh 1440p gaming but begins to buckle under 4K Ultra demands.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and tells a clear story about where the bottleneck lives. At High settings, the average frame rate falls from 171.5 FPS at 1920x1080 to 109 FPS at 2560x1440, then to 61.6 FPS at 3840x2160. That represents a 36.4% loss from 1080p to 1440p, followed by a 43.5% further drop from 1440p to 4K. The scaling is nearly linear with pixel count, which is the classic signature of a GPU-bound scenario.

The Low preset shows even more dramatic scaling. At 1080p Low, the system hits 229.2 FPS, which falls to 150.4 FPS at 1440p and then to 80.8 FPS at 4K. The 4K result is just 35.3% of the 1080p figure. This steep decline indicates that even at the lowest settings, the Radeon RX 6700 XT’s 12 GB frame buffer and 384.0 GB/s memory bandwidth are being taxed heavily by the 8.3 million pixels at 4K.

Interestingly, the gap between presets narrows as resolution climbs. At 1080p, the difference between Low and Ultra is 90.5 FPS (229.2 vs 138.7). At 4K, that spread compresses to 31.8 FPS (80.8 vs 49). This compression suggests that at 4K, the GPU’s compute throughput—13.21 TFLOPS FP32—becomes the limiting factor, overwhelming the settings-based overhead that dominates at lower resolutions.

The data indicates a system that scales predictably with resolution until 4K Ultra, where the 49 FPS average falls below the 60 FPS threshold typically desired for smooth play. At 1440p Ultra, the 88.4 FPS result shows the GPU still has headroom, but 4K Ultra pushes the combination past its comfort zone.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread Zen 2 part with a base clock of 3.70 GHz and a boost clock of 4.20 GHz. Its 8 MB shared L3 cache and dual-channel DDR4 memory support (51.2 GB/s bandwidth) set the foundation for feeding the GPU. In synthetic benchmarks, the chip scores 13593 in Cinebench R23 multi-core and 1919 in single-core. These numbers place it in the 75th percentile among all CPUs, meaning it outperforms three-quarters of the tested processors.

The CPU’s nearest rivals show how close the field is at this performance tier. The AMD Ryzen 3 PRO 5355GE scores 17482, a 0% delta from this chip’s average benchmark score of 17489. The Intel Core i5-12450H is just 0.1% behind, while the Intel Core i3-14100T trails by 0.8% and the Core i3-13100F by 1%. This clustering suggests the 4600G is right at the sweet spot for mid-range gaming, offering no clear advantage or disadvantage over its direct competitors.

In Doom, the CPU’s role is most evident at 1080p Low, where the 229.2 FPS result indicates the processor can keep up with the GPU’s output. The 3dmark 2-thread score of 1430 and single-thread score of 726 suggest adequate per-core performance for a game that, while not heavily threaded, still demands responsive frame pacing. With a PassMark multi-thread score of 15992, the 4600G demonstrates enough parallel capability to avoid becoming a bottleneck at 1440p, where the GPU takes over as the primary constraint.

GPU Role

The AMD Radeon RX 6700 XT is the star here, featuring 2560 shading units, 160 TMUs, and 64 ROPs on the Navi 22 chip. Its 12 GB of GDDR6 memory on a 192-bit bus delivers 384.0 GB/s bandwidth, which proves crucial for 4K performance. The GPU’s game clock runs at 2424 MHz with a boost of 2581 MHz, and it achieves 13.21 TFLOPS FP32 compute. This hardware sits in the 77th percentile among all GPUs, with an average benchmark score of 33721.

The GPU’s nearest rivals reveal its positioning. The AMD Radeon RX 6800 scores 33493, just 0.7% lower, while the AMD Radeon HD 7950 and RX 480 both score around 34050, about 1% higher. The NVIDIA RTX A5000 trails by 1.3%. This tight grouping suggests the 6700 XT is firmly mid-pack among high-end cards, edging out the RX 6800 but losing slightly to older architectures in synthetic tests.

In Doom, the GPU’s 77th percentile ranking translates to strong real-world results. At 1440p High, the 109 FPS average shows the card comfortably handling modern demands. The 4K High result of 61.6 FPS is playable, but the 4K Ultra figure of 49 FPS reveals the card’s limits. The 165.2 GPixel/s pixel rate and 413.0 GTexel/s texture rate provide the raw throughput needed for the game’s fast-paced environments, though the 40 RT cores go unused since Doom launched in 2016 without ray tracing support.

FAQ

*Q: Can this combination run Doom at 4K smoothly?*

A: At 4K High, the average FPS is 61.6, which is playable. However, 4K Ultra drops to 49 FPS, falling below the 60 FPS threshold. For consistent smoothness at 4K, stick to High settings or lower.

Q: What is the best resolution for high refresh rate monitors?

A: At 1440p Medium, the system produces 131.4 FPS, and 1440p High hits 109 FPS. These results are suitable for 120Hz or 144Hz displays. 1080p Low reaches 229.2 FPS, which exceeds even 240Hz monitor capabilities.

Q: How does the CPU compare to its direct competitors?

A: The Ryzen 5 4600G’s average benchmark score of 17489 is statistically tied with the Ryzen 3 PRO 5355GE (17482, 0% delta) and the Core i5-12450H (17475, 0.1% delta). It trails the Core i3-14100T by 0.8% and the Core i3-13100F by 1%.

Q: Is the GPU or CPU the limiting factor at 1080p?

A: At 1080p Low, the 229.2 FPS result suggests the GPU is still the primary constraint, as the CPU’s 6 cores and 12 threads can feed frames faster. The 3dmark 16-thread score of 4863 indicates the processor has headroom beyond what the GPU can utilize.

Q: What is the performance difference between Low and Ultra settings?

A: At 1080p, Ultra is 39.5% slower than Low (138.7 vs 229.2 FPS). At 1440p, the gap narrows to 41.2% (88.4 vs 150.4 FPS). At 4K, Ultra is 39.4% slower (49 vs 80.8 FPS). The percentage drop remains consistent across resolutions.

*Q: How does this combo rank among all tested systems in Doom?*

A: This specific CPU/GPU pairing ranks 934 out of 1681 total combinations, placing it in the 55.6th percentile. This indicates a slightly above-average setup for this particular game.

Settings Recommendations

The measured data points to 1440p High as the optimal balance of visual quality and performance. At 2560x1440 with High settings, the system delivers 109 FPS, which is smooth for fast-paced FPS gameplay while maintaining the visual fidelity that High presets offer. The jump to Ultra at the same resolution costs 20.6 FPS (109 to 88.4), a 18.9% reduction that may not justify the visual gains.

For players prioritizing maximum frame rates, 1080p Low offers 229.2 FPS, which is ideal for competitive play or esports scenarios. The Medium preset at 1080p still provides 200.2 FPS, offering a better visual experience with only a 12.7% performance hit. At 4K, High settings are the only viable option, as the 61.6 FPS average keeps gameplay fluid, while Ultra’s 49 FPS introduces noticeable stutter.

The data suggests avoiding 4K Ultra entirely, as the 49 FPS result is below the 60 FPS baseline for comfortable play. Similarly, 1080p Ultra at 138.7 FPS is strong, but the 31.7% drop from Low makes it less appealing than Medium’s 200.2 FPS. For most users, 1440p High represents the sweet spot, delivering 109 FPS without sacrificing the visual richness that Doom’s 2016 engine can produce. The 12 GB VRAM and 384.0 GB/s bandwidth of the RX 6700 XT ensure that High presets have ample memory headroom at this resolution.
