Doom

The AMD Ryzen 5 7600 paired with the NVIDIA GeForce RTX 4090 is a combination that prioritizes raw GPU muscle, and the data for Doom reflects that imbalance clearly. This is a system built for maximum frame rates, and the measured results show exactly how far the RTX 4090 can push this 2016 title, even when paired with a mid-range 6-core CPU.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals a classic transition from CPU to GPU limitation. At 1920x1080 with Low settings, the combo delivers 406.9 FPS, but this is not a practical gaming scenario; it is a measure of how far the CPU can push the engine. The drop to 1440p Low is significant, falling to 285.4 FPS, a decrease of approximately 30%. This steep decline indicates that the CPU is still heavily involved at these settings, as the GPU is not yet the bottleneck.

Moving to 4K, the scaling pattern shifts. At 3840x2160 Low, the average FPS is 156.4, which is a 45% reduction from the 1440p figure. This larger drop shows the GPU is now becoming the primary constraint, as the pixel throughput demand skyrockets. The trend is consistent across all settings: the gap between 1080p and 1440p is smaller than the gap between 1440p and 4K, confirming that the RTX 4090 is the limiting factor at higher resolutions. For example, at High settings, the drop from 1080p (325 FPS) to 1440p (213 FPS) is 34%, while the drop from 1440p to 4K (112.4 FPS) is 47%. This pattern solidifies the argument that 4K is where the GPU is fully saturated, and the CPU's influence on performance wanes.

GPU Role

The RTX 4090 is the undisputed star of this configuration, and its specifications explain the 4K performance. It is equipped with 24 GB of GDDR6X memory on a 384-bit bus, providing 1.01 TB/s of bandwidth. This massive memory pool is overkill for Doom, but it ensures that texture loading and memory allocation are never a bottleneck, even at Ultra settings where the game may consume more VRAM. The GPU's architecture, Ada Lovelace, is built on a 5 nm process and contains 76,300 million transistors, a figure that underscores its computational density.

Clock speeds are also a factor. The base clock is 2235 MHz, with a boost clock of 2520 MHz. These high frequencies, combined with the 16384 shading units, allow the card to process the game's geometry and effects with immense speed. The data supports this: at 4K Ultra, the combo still manages 93.1 FPS, a playable frame rate for a single-player FPS. The GPU's benchmark scores also place it in the 91st percentile of all GPUs, with an average benchmark score of 66473. While its nearest rivals in the database (Tesla T4, Tesla P40, Radeon Pro Vega 56) are close in that synthetic metric, they are not gaming cards, and the measured FPS here is what matters for this analysis.

Settings Recommendations

The measured data provides a clear hierarchy for settings, and the "sweet spot" depends on your display and preference for visual fidelity versus raw speed. If you own a 240Hz 1080p monitor, the Medium preset at 388.2 FPS is the optimal choice, as it offers a significant frame rate advantage over High (325 FPS) while still looking substantially better than Low (406.9 FPS). The difference between Medium and Low (18.6 FPS) is not worth the visual quality loss, but the jump from High to Medium (63.2 FPS) is a massive gain for a minimal visual compromise.

For 1440p users with high-refresh displays, High at 213 FPS is the most balanced option. It is comfortably above 144Hz and even 165Hz refresh rates. Medium at 248.9 FPS is faster but may introduce more noticeable texture detail degradation. Ultra at 174.4 FPS is still excellent, but the 38.6 FPS loss versus High is a steep price for marginal visual gains in a game like Doom. At 4K, the choice is between High (112.4 FPS) and Medium (133.6 FPS). High is the recommended starting point, as it stays above 100 FPS and offers the best visual experience. If you need to push closer to a 144Hz 4K panel, switching to Medium yields a 21.2 FPS improvement, which is a worthwhile trade-off.

Measured FPS Breakdown

The complete dataset shows consistent scaling across resolutions and settings. At 1920x1080, the averages are: Low 406.9 FPS, Medium 388.2 FPS, High 325 FPS, and Ultra 270.5 FPS. The performance is so high that it is likely capped by the CPU's single-thread performance or engine limits, not the GPU.

At 2560x1440, the averages are: Low 285.4 FPS, Medium 248.9 FPS, High 213 FPS, and Ultra 174.4 FPS. This resolution is the ideal balance for this combo, offering frame rates that can fully saturate high-refresh monitors.

At 3840x2160, the averages are: Low 156.4 FPS, Medium 133.6 FPS, High 112.4 FPS, and Ultra 93.1 FPS. Here, the RTX 4090 is working hard, and the frame rates begin to reflect the demands of 4K rendering. The transition from Low to Ultra at 4K costs 63.3 FPS, showing that the Ultra preset is not free.

How This Combo Ranks

With a combo rank of 33 out of 1681 tested combinations, this system is in the top 2% of all configurations in the database for Doom. This is an exceptional result, placing it far ahead of the vast majority of builds. The rank reflects the dominance of the RTX 4090, which is the primary driver of high FPS in this title.

The CPU's contribution is secondary but not negligible. The Ryzen 5 7600 is a 6-core, 12-thread processor with a boost clock of 5.10 GHz, and it sits in the 83rd percentile of all CPUs. Its average benchmark score of 26617 is virtually identical to its nearest rival, the AMD Ryzen 7 5800X3D, with a deltaPct of only 0.2%. This means the 7600 is not holding back the GPU at higher resolutions, where the GPU is the bottleneck. The CPU's strong single-thread score (999 in 3dmark_single_thread) is sufficient to feed the RTX 4090, even at 1080p, where the frame rates are astronomical. The ranking suggests that while the CPU is not the top performer, it is more than adequate to enable this GPU to reach its full potential in Doom.

FAQ

Q: Is this combo overkill for Doom at 1080p?

A: Yes. The data shows frame rates exceeding 270 FPS even at Ultra settings (270.5 FPS). This far exceeds the refresh rate of most 1080p monitors, indicating the GPU is not being fully utilized at this resolution.

Q: What is the best resolution to use for this combo?

A: The 2560x1440 resolution offers the best balance. The measured results show High settings at 213 FPS and Ultra at 174.4 FPS, which provides high visual quality while still delivering frame rates that can take advantage of high-refresh monitors.

Q: How much performance is lost by switching from High to Ultra at 4K?

A: The data shows a drop from 112.4 FPS on High to 93.1 FPS on Ultra at 3840x2160. This is a 19.3 FPS difference, which is a significant cost for the visual enhancements of the Ultra preset.

Q: Can this system achieve 4K 120 FPS in Doom?

A: Yes, but only on the High settings preset. The measured average FPS at 4K High is 112.4. Lower settings (Medium at 133.6 FPS and Low at 156.4 FPS) will also exceed 120 FPS, but Ultra will not, as it averages 93.1 FPS.

Q: Is the CPU a bottleneck for the RTX 4090 in this game?

A: At 4K, no. The scaling from 1440p to 4K shows a significant FPS drop, indicating the GPU is the limiting factor. At 1080p, the CPU may be a constraint, as the frame rates are extremely high and likely limited by processing capability.

Q: How does this combo compare to others in the database for Doom?

A: It ranks 33rd out of 1681 tested combinations. This places it in the top 2% of all tested systems, demonstrating that it is one of the most powerful configurations available for this specific game.
