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

The measured FPS data for Doom with the AMD Ryzen 9 7900X and NVIDIA GeForce RTX 3060 Ti reveals a clear and consistent scaling pattern as resolution climbs. At 1080p with Low settings, the combo achieves 192.2 FPS. Moving to 1440p Low drops that to 126.9 FPS, a reduction of roughly one-third. At 4K Low, the average falls further to 69.6 FPS. This trajectory is steep, but it is not uniform across all settings.

Looking at the High preset, the scaling is more moderate. At 1080p High, the system produces 139.7 FPS. At 1440p High, it delivers 91.2 FPS. At 4K High, the average sinks to 48.5 FPS. The drop from 1080p to 1440p is about 35%, while the drop from 1440p to 4K is about 47%. These percentages indicate that the GPU is becoming the dominant constraint as pixel count grows, but the CPU still has enough headroom to feed the graphics card at lower resolutions.

The data strongly implies that at 1080p, the system is not purely GPU-limited. The gap between Low (192.2 FPS) and Ultra (117.6 FPS) at 1080p is 74.6 FPS, a substantial spread that shows settings have a major impact. At 4K, the same Low-to-Ultra spread is only 31.7 FPS (69.6 vs. 37.9). This compression of the settings delta at higher resolutions is a classic sign that the GPU is saturated at 4K, making the choice of preset less consequential there. Conversely, at 1080p, the CPU and GPU are both working hard, and the settings slider has a much larger effect on the final frame rate.

The extreme case is 4K Ultra, where the average FPS drops to 37.9. This is below the 48.5 FPS seen at 4K High, and it is a clear indicator that the RTX 3060 Ti's 8 GB of GDDR6 memory and its 256-bit bus are being pushed to their limits with the most demanding settings at this resolution. The scaling pattern suggests that for a smooth experience at 4K, users must be willing to dial back settings significantly, as even Low settings only yield 69.6 FPS there.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 3060 Ti is built on the Ampere architecture with a GA104 chip, fabricated on Samsung's 8 nm process. Its base clock is 1410 MHz, which boosts to 1665 MHz. The memory configuration is 8 GB of GDDR6 on a 256-bit bus, delivering a bandwidth of 448.0 GB/s. The memory clock is listed at 1750 MHz, with 14 Gbps effective transfer rate. These specs are directly relevant to the measured FPS, particularly at higher resolutions.

The 8 GB VRAM capacity is a critical factor in the 4K results. The data shows a sharp drop in performance when moving from High to Ultra at 4K: 48.5 FPS to 37.9 FPS. This 10.6 FPS decline is the largest single-step drop in the entire dataset. The likely cause is the combination of higher resolution textures and effects pushing against the 8 GB limit, forcing the GPU to manage memory more aggressively. The 448.0 GB/s bandwidth is sufficient for 1080p and 1440p, but at 4K with Ultra settings, the memory subsystem appears to become a bottleneck.

The GPU's pixel rate is 133.2 GPixel/s and its texture rate is 253.1 GTexel/s. These figures explain why the card handles 1440p High at 91.2 FPS but struggles to maintain 60 FPS at 4K High. The fill rate requirements at 4K are substantially higher, and the data shows the card's limits are reached there. The FP32 performance of 16.20 TFLOPS is the raw compute capability, and while Doom is not the most compute-heavy title, the 4K Ultra result suggests that even this level of throughput is insufficient for max settings at that resolution.

The GPU's percentile rank among all GPUs is 69, and its average benchmark score is 25120. Its nearest rivals in the database include the AMD Radeon RX 6700M (with a deltaPct of -0.2), the AMD Radeon RX 6600 (-0.5), and the AMD Radeon 890M (-0.5). These are all very close in average score, indicating that the RTX 3060 Ti sits in a tightly contested performance tier. In this game specifically, the measured results show it can deliver high frame rates at 1080p and 1440p, but 4K requires careful settings management.

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

The complete dataset for this combo in Doom is as follows:

1920x1080:

• Low: 192.2 FPS
• Medium: 167.6 FPS
• High: 139.7 FPS
• Ultra: 117.6 FPS

2560x1440:

• Low: 126.9 FPS
• Medium: 108.4 FPS

• Ultra: 76.6 FPS

3840x2160:

• Low: 69.6 FPS
• Medium: 56.4 FPS
• High: 48.5 FPS
• Ultra: 37.9 FPS

At 1080p, every preset exceeds 100 FPS, with the Low preset nearly reaching 200 FPS. The spread from Ultra to Low is 74.6 FPS, showing that the settings menu has a powerful influence at this resolution. The Medium preset at 167.6 FPS is notably close to Low, with only a 24.6 FPS gap, while High is 27.9 FPS behind Medium.

At 1440p, the pattern shifts. Low still delivers a very playable 126.9 FPS, and Medium is at 108.4 FPS. High drops to 91.2 FPS, which is still above 90 FPS, and Ultra falls to 76.6 FPS. The spread from Ultra to Low is 50.3 FPS, which is narrower than at 1080p, indicating the GPU is starting to become the limiting factor.

At 4K, the numbers compress further. Low is 69.6 FPS, Medium is 56.4, High is 48.5, and Ultra is 37.9. The spread is only 31.7 FPS. No preset reaches the 90 FPS mark, and only Low manages to stay above 60 FPS. The step from Medium to High is 7.9 FPS, while the step from High to Ultra is 10.6 FPS, the largest single-step drop in the dataset.

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

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor based on the Zen 4 architecture (codenamed Raphael), manufactured on TSMC's 5 nm process. It has a base clock of 4.70 GHz and a boost clock of 5.60 GHz. The L3 cache is 64 MB shared, with 1 MB L2 per core and 64 KB L1 per core. This is a high-end desktop CPU, and its performance in synthetic benchmarks is strong. In Cinebench R23, it scores 43695 multicore and 6168 singlecore. In Geekbench, it reaches 17830 multicore and 2952 singlecore.

For Doom, which is a game that can be sensitive to single-thread performance, the 7900X's boost clock of 5.60 GHz and its singlecore score of 6168 in Cinebench R23 are important. The measured FPS at 1080p Low (192.2) is high, but it is not the absolute ceiling of the CPU. The fact that Ultra settings at 1080p drop to 117.6 FPS, while Low stays near 200, suggests that the CPU is not the primary bottleneck at 1080p Low. The GPU is still doing the heavy lifting.

However, the CPU's capability is evident in the scaling behavior. At 4K Low, the FPS is 69.6, which is a 63.8% drop from 1080p Low. If the CPU were severely limiting, we would expect the FPS to remain closer to the 1080p value as resolution increases, since the CPU work per frame is roughly constant. The fact that FPS drops so significantly at 4K indicates the GPU is the limiting component. The 7900X has enough headroom to feed the RTX 3060 Ti at all tested settings, and the data shows no signs of CPU-induced plateaus.

The CPU's percentile rank is 93 among all CPUs, and its average benchmark score is 50556. Its nearest rivals include the Intel Core Ultra 5 235 (deltaPct -0.1), the AMD Ryzen 9 5900XT (-0.4), and the Intel Core i9-13980HX (-0.8). These are all within 0.8% of the 7900X's average score, placing it in a performance tier where the differences are negligible. In this game, the 7900X's 12 cores and 24 threads are more than sufficient, and the limiting factor is squarely the GPU, especially at higher resolutions.

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

Based on the measured FPS data, the optimal settings preset depends heavily on the target resolution and desired frame rate. At 1080p, all presets are playable, but the data suggests that Medium offers the best balance. Medium yields 167.6 FPS, which is 27.9 FPS higher than High (139.7 FPS) and 50 FPS higher than Ultra (117.6 FPS). The visual difference between Medium and High in a fast-paced FPS like Doom is often less impactful than the frame rate advantage. If the goal is to maximize smoothness, Low at 192.2 FPS is the choice, but Medium provides a substantial quality boost with a still-very-high frame rate.

At 1440p, the recommendation shifts. Low at 126.9 FPS is the only preset that comfortably exceeds 120 FPS. Medium at 108.4 FPS is still excellent for high-refresh monitors. High at 91.2 FPS is above 90, and it offers a better visual experience. Ultra at 76.6 FPS is playable but begins to approach the lower limits of high-refresh gaming. For a 1440p monitor with a 144 Hz refresh rate, Medium is the recommended preset, as it provides a frame rate that is close to the refresh ceiling while maintaining better visuals than Low.

At 4K, the choices are more constrained. Only Low (69.6 FPS) manages to stay above 60 FPS. Medium (56.4) and High (48.5) are below 60, and Ultra (37.9) is firmly in the field of slower, more cinematic frame rates. For 4K gaming, the data suggests that Low is the only preset that provides a consistently smooth experience. If the user is willing to accept frame rates in the 40-50 range, High offers a significant visual upgrade over Low, but the measured 48.5 FPS may not be ideal for a twitch shooter. Medium at 56.4 FPS is a middle ground, but it still misses the 60 FPS mark.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the AMD Ryzen 9 7900X and the NVIDIA GeForce RTX 3060 Ti ranks 1199 out of 1681 tested combos in Doom. This places it in the 71st percentile from the bottom, meaning it outperforms roughly 29% of tested configurations but is outpaced by the majority. This ranking is notable given the strength of the CPU, which ranks in the 93rd percentile among all CPUs. The GPU, in contrast, ranks in the 69th percentile among all GPUs.

The data implies that the combo's ranking in this game is dragged down by the GPU. The 7900X is a top-tier processor, but the RTX 3060 Ti is a mid-range card. In a game like Doom, which is well-optimized and can scale to high frame rates, the GPU becomes the limiting factor at higher resolutions. The measured FPS at 1080p Low (192.2) shows the CPU is capable of pushing very high frame rates, but the GPU's limits are exposed at 4K Ultra (37.9 FPS).

The rank of 1199 out of 1681 suggests that many other combos, likely those with more powerful GPUs, achieve higher average frame rates in this title. The data does not specify what those combos are, but the ranking is clear. For users with a 7900X, pairing it with a stronger GPU would likely yield a much higher rank. Conversely, the RTX 3060 Ti performs admirably for its tier, and the ranking reflects the GPU's position rather than any CPU deficiency. The combo is well-balanced for 1080p and 1440p gaming, but it is not optimized for 4K max settings, as the ranking indicates.
