Doom

The AMD Ryzen 5 3600 pairs with the NVIDIA GeForce RTX 3060 Ti as a mid-generation desktop combo built on the AM4 socket. The CPU brings six cores and twelve threads, with a base clock of 3.60 GHz and a boost clock of 4.20 GHz, while the GPU uses the Ampere architecture with 4864 shading units and 8 GB of GDDR6 memory on a 256-bit bus. In Doom, this combination produces a wide spread of frame rates depending on resolution and settings, ranging from 40.4 FPS at 4K Ultra to 189.9 FPS at 1080p Low. The benchmark data shows a system that is clearly capable of high-refresh 1080p play, but one that begins to strain as resolution climbs toward 4K.

CPU Role — cores, clocks, and how they relate to this game's results

The Ryzen 5 3600’s six cores and twelve threads are built on the Zen 2 architecture, manufactured on a 7 nm process at TSMC. Its 32 MB shared L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth provide a solid foundation for feeding a discrete GPU. In Doom, which is a fast-paced FPS, the CPU’s single-thread performance matters for maintaining high frame rates, especially at lower resolutions where the GPU is not the bottleneck.

Looking at the CPU’s benchmark scores, the 3DMark single-thread test returns 696, while the Cinebench R23 single-core score is 2124. These numbers indicate decent per-core strength, which is sufficient for Doom’s engine. The multi-threaded scores are more robust: Cinebench R23 multicore reaches 15045, and PassMark multithread scores 17700. The 3DMark 16-thread score of 4605 and max-thread score of 4603 show that the CPU scales well across its twelve threads, but Doom does not heavily rely on that many cores.

In practice, the CPU’s role becomes most apparent when comparing frame rates across settings at the same resolution. At 1080p Low, the combo hits 189.9 FPS, which is far above any refresh-rate target for most monitors. At 1080p Ultra, the frame rate drops to 115.1 FPS, a 39.4% reduction, suggesting the GPU is taking on more work as settings increase. The CPU’s 76th percentile ranking against all CPUs, with an average benchmark score of 18129, places it in the upper-middle tier. Its nearest rival, the Intel Core i5-11400, scores 18150, a delta of -0.1%, meaning the Ryzen 5 3600 is effectively tied with that Intel part in overall CPU performance. For Doom specifically, the data indicates the CPU is rarely the limiting factor; the GPU does most of the heavy lifting once resolution and settings rise.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data shows a clear pattern of diminishing returns as resolution increases. Starting at 1920x1080 with High settings, the combo delivers 140.9 FPS. Moving to 2560x1440 at the same settings, the frame rate drops to 90.1 FPS, a reduction of 36.1% from the 1080p figure. At 3840x2160 High, the average FPS falls to 48.8, which is 65.4% lower than the 1080p High result. This steep decline is characteristic of a GPU-bound scenario.

The same trend holds across all settings. At Low settings, 1080p yields 189.9 FPS, 1440p yields 125.7 FPS, and 4K yields 68.3 FPS. The drop from 1080p to 1440p is 33.8%, and from 1440p to 4K is 45.7%. For Ultra settings, the progression is 115.1 FPS at 1080p, 73.5 FPS at 1440p, and 40.4 FPS at 4K. The percentage drops are 36.1% and 45.0% respectively.

What this scaling reveals is that the RTX 3060 Ti is the primary limiter at higher resolutions. The CPU’s performance headroom is ample at 1080p, where frame rates exceed 115 FPS even at Ultra. As resolution increases, the GPU’s fill rate and memory bandwidth become the constraining factors. The GPU’s 448.0 GB/s memory bandwidth and 133.2 GPixel/s pixel rate are simply insufficient to maintain high frame rates at 4K with demanding settings. The data suggests that for 4K play, users would need to rely on Low settings to achieve a playable 68.3 FPS, and even then, that is below the 70 FPS threshold some might prefer for a fast shooter.

How This Combo Ranks — use comboRankInGame vs other tested combos

In the database of tested CPU-GPU combinations for Doom, this pairing of the AMD Ryzen 5 3600 and NVIDIA GeForce RTX 3060 Ti ranks 1237 out of 1681 total combinations. This places it in the 26.4th percentile of all tested combos, meaning roughly three-quarters of the tested systems perform better in this game. That ranking may seem low given the respectable frame rates at 1080p, but it reflects the fact that Doom is a well-optimized title that can run on a wide range of hardware, and many of the tested combos likely feature higher-end GPUs or newer CPUs.

To put this in context, the CPU’s nearest rivals include the Intel Core i5-11400 with an average score of 18150 and a delta of -0.1%, meaning the Ryzen 5 3600 is essentially on par with that chip. The AMD Ryzen 5 7535HS scores 18101, a 0.2% delta, and the AMD Ryzen 5 1600 scores 18158, a -0.2% delta. These small differences confirm that the CPU is not a differentiator in this ranking. Similarly, the GPU’s nearest rivals include the AMD Radeon RX 6700M with an average score of 25180 (-0.2% delta), the AMD Radeon RX 6600 at 25235 (-0.5%), and the AMD Radeon 890M at 25246 (-0.5%). Again, the RTX 3060 Ti’s score of 25120 is within 0.5% of these competitors, showing that the GPU is also mid-pack in its class.

The low combo rank likely results from the combination of a mid-range CPU and a mid-range GPU relative to the full field of tested systems, which includes many high-end parts. For the price segment this combo occupies, the measured performance is reasonable, but the data clearly shows it is not positioned near the top of the overall rankings.

Settings Recommendations — which preset gives the best experience per the measured rows

For 1080p gaming, the data supports using High or Ultra settings. At High, the combo delivers 140.9 FPS, which is smooth for any 144 Hz monitor. Ultra drops to 115.1 FPS, still above 100 FPS and acceptable for competitive play, but the visual gains from Ultra over High are typically marginal in Doom. Medium settings produce 164.5 FPS, which is overkill for most displays, while Low at 189.9 FPS offers no practical benefit unless using a 240 Hz panel. Given the small FPS difference between High and Medium (23.6 FPS), High is the better choice for visual fidelity without sacrificing much speed.

At 1440p, the situation changes. High settings yield 90.1 FPS, which is playable but not ideal for high-refresh monitors. Medium produces 108.1 FPS, a 20% improvement over High, while Low hits 125.7 FPS. Ultra drops to 73.5 FPS, which is borderline for a 75 Hz display but not for 144 Hz. For 1440p, Medium is the sweet spot, offering a balance of visual quality and frame rate that stays above 100 FPS. If a higher frame rate is preferred, Low at 125.7 FPS is the safer bet, but it sacrifices significant graphical detail.

At 4K, no setting reaches 70 FPS. High gives 48.8 FPS, Medium gives 61.2 FPS, Low gives 68.3 FPS, and Ultra gives 40.4 FPS. For 4K, Low is the only setting that approaches playable territory, but 68.3 FPS is still below the 60 FPS threshold for many users, and it is far from smooth for a fast-paced FPS. The data suggests that 4K is not a practical target for this combo in Doom, and users should stick to 1080p or 1440p for the best experience.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the combo produces the following average FPS across four settings:

• Low: 189.9 FPS
• Medium: 164.5 FPS
• High: 140.9 FPS
• Ultra: 115.1 FPS

The spread from Low to Ultra is 74.8 FPS, with each step up in settings costing roughly 24-25 FPS. The difference between Low and Medium is 25.4 FPS, Medium to High is 23.6 FPS, and High to Ultra is 25.8 FPS. This consistent drop indicates that each settings tier adds a similar load on the GPU.

At 2560x1440, the results are:

• Low: 125.7 FPS
• Medium: 108.1 FPS
• High: 90.1 FPS
• Ultra: 73.5 FPS

The total spread here is 52.2 FPS. The gaps between settings are 17.6 FPS (Low to Medium), 18.0 FPS (Medium to High), and 16.6 FPS (High to Ultra). The smaller absolute differences compared to 1080p reflect the increased GPU load, which compresses the frame rate range.

At 3840x2160, the results are:

• Low: 68.3 FPS
• Medium: 61.2 FPS
• High: 48.8 FPS
• Ultra: 40.4 FPS

The spread is 27.9 FPS, with gaps of 7.1 FPS (Low to Medium), 12.4 FPS (Medium to High), and 8.4 FPS (High to Ultra). The compression here is severe, as the GPU is clearly overwhelmed at 4K. Even the jump from Low to Medium, which is only 7.1 FPS, shows that the GPU has little headroom left at this resolution.

Comparing across resolutions at the same setting, the data shows that 1080p High (140.9) is 56.4% faster than 1440p High (90.1), and 1440p High is 84.6% faster than 4K High (48.8). At Low settings, 1080p Low (189.9) is 51.1% faster than 1440p Low (125.7), and 1440p Low is 84.0% faster than 4K Low (68.3). These percentages highlight how the GPU becomes the dominant bottleneck as pixel count rises. The RTX 3060 Ti’s 8 GB of GDDR6 memory and 256-bit bus are adequate for 1080p and 1440p, but the 4K results confirm that this combo is not designed for that resolution in Doom.
