Doom

The AMD Ryzen 5 5600G paired with the NVIDIA GeForce RTX 3070 delivers a remarkably consistent 1080p experience in Doom, but the data reveals a clear transition point where the GPU becomes the primary driver of performance. At 1080p with Low settings, the combo achieves 260.6 FPS, which drops to 157.4 FPS at Ultra settings—a substantial 103.2 FPS swing that highlights the graphics card’s workload. However, the scaling pattern shifts dramatically at 4K, where the difference between Low (91.7 FPS) and Ultra (57.5 FPS) narrows to 34.2 FPS, indicating that the RTX 3070’s rendering capabilities are being taxed more heavily at higher resolutions. This behavior is classic GPU-bound scaling: the CPU has enough headroom to feed the GPU at lower resolutions, but as pixel count rises, the graphics card’s fill rate and memory bandwidth become the limiting factors.

Resolution Scaling

The measured FPS data shows a predictable yet telling decline as resolution increases. At 1080p High, the combo produces 189.6 FPS, which falls to 122.4 FPS at 1440p (a 35.4% reduction) and then to 65.7 FPS at 4K (a further 46.3% drop). This steep 4K penalty—roughly one-third of the 1080p performance—suggests that the RTX 3070’s 8 GB of GDDR6 memory and 448.0 GB/s bandwidth are being saturated, rather than the Ryzen 5 5600G’s six cores holding things back. The Low preset tells a similar story: 260.6 FPS at 1080p, 164.6 FPS at 1440p, and 91.7 FPS at 4K. The percentage drop from 1080p to 4K is 64.8% for Low, but only 65.3% for High, indicating that the resolution scaling penalty is nearly uniform regardless of settings—a hallmark of a GPU that is consistently the bottleneck.

The real insight comes from comparing Medium and Ultra across resolutions. At 1080p, Medium (222.9 FPS) and Ultra (157.4 FPS) differ by 65.5 FPS, but at 4K, the gap shrinks to 22.4 FPS (79.9 vs. 57.5). This compression at higher resolutions suggests that even the Ultra preset’s additional effects are less impactful when the GPU is already struggling to fill 8.3 million pixels. For gamers targeting 1440p, the combo delivers a playable 102.4 FPS at Ultra, but dropping to High (122.4 FPS) or Medium (149 FPS) provides a much smoother experience without sacrificing too much visual fidelity. The data makes it clear: this is a 1080p and 1440p champion, with 4K being possible only at lower settings.

GPU Role

The NVIDIA GeForce RTX 3070 is the star of this show, and its specs explain why. With 5888 shading units, 184 texture mapping units, and 96 ROPs, the GPU is well-equipped for Doom’s fast-paced rendering. The boost clock of 1725 MHz, combined with 8 GB of GDDR6 memory on a 256-bit bus, provides a theoretical bandwidth of 448.0 GB/s—a figure that proves crucial at 4K. The benchmark results support this: at 4K Low, the combo hits 91.7 FPS, but at 4K High, it drops to 65.7 FPS. This 26.0 FPS penalty from Low to High at 4K is smaller than the 71.0 FPS penalty at 1080p (260.6 to 189.6 FPS), reinforcing that the GPU’s pixel throughput, not its memory capacity, is the limiting factor at higher resolutions.

The RTX 3070’s 20.31 TFLOPS of FP32 compute is more than sufficient for Doom, which launched in 2016 and does not rely on ray tracing or DLSS. The GPU’s 72nd percentile ranking among all GPUs, with an average benchmark score of 28238, places it in the upper tier, but its nearest rivals—the AMD Radeon RX 6600 XT (27985, 0.9% slower) and the NVIDIA GeForce GTX 980 Ti (27956, 1.0% slower)—show that it’s not a class leader. The data indicates that the RTX 3070 is delivering close to its expected performance, with no signs of CPU-induced stuttering or frame pacing issues. The 14 Gbps effective memory speed and 256-bit interface are well-matched to the card’s compute capabilities, ensuring that texture streaming and geometry processing keep pace with the shading units.

CPU Role

The AMD Ryzen 5 5600G, with its 6 cores and 12 threads, plays a supporting but non-trivial role. Its base clock of 3.90 GHz and boost clock of 4.40 GHz, based on the Zen 3 architecture, provide strong single-threaded performance that Doom’s engine can leverage. The CPU’s 16 MB of L3 cache and 512 KB per-core L2 cache help reduce memory latency, which is critical for maintaining high frame rates in a game that often relies on draw calls and physics updates. In synthetic benchmarks, the 5600G scores 2365 in Cinebench R23 single-core and 16758 in multi-core, placing it in the 78th percentile of all CPUs. Its nearest rivals—the Intel Core i7-11600H (19949, 0.2% slower) and the Intel Core i7-11800H (20024, 0.2% faster)—are remarkably close, confirming that the 5600G is a balanced mid-range processor.

Crucially, the benchmark data shows no scenario where the CPU becomes the bottleneck. At 1080p Low, the combo hits 260.6 FPS, which is likely near the engine’s maximum frame rate limit, rather than a CPU constraint. The 5600G’s 3DMark scores—5455 for max threads and 872 for single thread—indicate it can handle Doom’s threading model, which typically scales well up to 8 threads. The CPU’s 65 W TDP and 7 nm process node (TSMC) mean it runs cool and efficient, leaving thermal headroom for the GPU. In short, the Ryzen 5 5600G is more than adequate for this GPU pairing; it neither boosts nor restricts the RTX 3070’s output, allowing the graphics card to dictate performance at every resolution.

How This Combo Ranks

In the database of 1681 tested combos, this pairing of the Ryzen 5 5600G and RTX 3070 ranks 774th for Doom. This places it in the upper-middle tier, which is surprising given the GPU’s raw power. The rank suggests that while the combo is capable, there are many other pairings that deliver higher frame rates, likely due to more powerful CPUs or newer GPUs. The 5600G’s integrated Radeon Vega 7 graphics are irrelevant here, as the discrete RTX 3070 is doing all the work, but the CPU’s 78th percentile ranking among all CPUs is slightly lower than the GPU’s 72nd percentile, indicating a balanced but not top-tier pairing.

Relative to the GPU’s nearest rivals, the RTX 3070 is competitive. It sits 0.9% ahead of the RX 6600 XT and 1.0% ahead of the GTX 980 Ti in average benchmark scores, but 1.1% behind the Radeon R9 M295X. These small deltas suggest that the RTX 3070 is not a standout performer in synthetic tests, yet the measured FPS in Doom—particularly the 189.6 FPS at 1080p High—shows it excels in real-world gaming. The combo’s rank of 774 out of 1681 means it outperforms 53.8% of tested configurations, which is respectable but not exceptional. For a 2020 GPU paired with a 2021 CPU, this results in a system that is well-suited for high-refresh-rate 1080p and 1440p gaming, but it would be outclassed by newer hardware like the RTX 40-series.

Settings Recommendations

For the best balance of visual quality and frame rate, the data points to the High preset at 1440p as the sweet spot. At 122.4 FPS, it delivers a smooth experience on high-refresh monitors, while maintaining visual fidelity that is only 19.1% slower than Medium at the same resolution (149 FPS). At 1080p, High (189.6 FPS) is excellent for competitive play, but Ultra (157.4 FPS) offers a marginal visual upgrade that some players may prefer. The Low preset at 1080p (260.6 FPS) is overkill unless the goal is extreme frame rates for esports titles, though Doom’s fast-paced action benefits from any extra headroom.

At 4K, the choices are more constrained. Medium (79.9 FPS) is the highest playable preset, while High (65.7 FPS) is borderline and Ultra (57.5 FPS) dips below the 60 FPS threshold. For players with 4K displays, Medium is the recommended setting, as it provides a 24.2 FPS improvement over Ultra while looking noticeably better than Low (91.7 FPS). The data suggests that High at 1440p is the overall best experience, offering 122.4 FPS with detailed textures and effects, but for those prioritizing frame rate, Medium at 1440p (149 FPS) or High at 1080p (189.6 FPS) are both viable alternatives that avoid the steep 4K penalty.
