Doom

The AMD Ryzen 7 7800X3D and NVIDIA GeForce RTX 4080 SUPER combination delivers exceptional performance in Doom, consistently producing high frame rates that are well above the threshold for smooth competitive play. The data indicates that this pairing is heavily GPU-bound at higher resolutions, while the CPU's strong multi-threaded capabilities ensure that even at 1080p, the system avoids becoming a bottleneck. This analysis breaks down the measured performance metrics to show exactly how each component contributes to the final frame rates.

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

The AMD Ryzen 7 7800X3D is an 8-core, 16-thread processor based on the Zen 4 architecture, with a base clock of 4.20 GHz and a boost clock of 5.00 GHz. Its substantial 96 MB of shared L3 cache is a key asset for game performance, as it reduces memory latency and improves data access speeds for the game engine. The processor's benchmark scores show strong multi-threaded performance, with a Cinebench R23 multicore score of 29149 and a Geekbench multicore score of 15101, indicating that it can easily handle the game's rendering threads alongside other background tasks.

In Doom, the CPU's role is to prepare frames for the GPU to render. The data shows that at 1920x1080 with Low settings, the system achieves 395.7 FPS, which is the highest average frame rate measured. This high result suggests that the CPU is capable of feeding the GPU with a massive number of draw calls without becoming a limiting factor. The 7800X3D's single-thread performance, reflected in a Cinebench R23 singlecore score of 4115, is also critical for the game's main game logic thread. This combination of high single-thread and multi-thread performance ensures that the CPU is not a bottleneck, even when the GPU is tasked with producing hundreds of frames per second. The processor's average benchmark score of 31580 places it in the 87th percentile of all CPUs, and it benchmarks within 0.6% of rivals like the AMD Ryzen 7 7745HX and the Intel Core i7-12700F, confirming its top-tier status.

When looking at the broader picture, this specific combination of the Ryzen 7 7800X3D and RTX 4080 SUPER ranks 106th out of 1681 tested combos for this game. This placement in the top 6.3% of all combinations tested is a strong indicator of the system's overall capability. The high rank is a direct result of both components performing at a high level, with neither creating a significant bottleneck in the test scenarios. The data shows that this combo is not just a high-end pairing on paper; it delivers a top-tier experience in practice, as reflected in its measured frame rates.

The rank of 106 out of 1681 demonstrates that while there are faster combinations, this pairing is firmly in the upper echelon of performance. The score is a holistic measure of how well the CPU and GPU work together in this specific game. This performance is attributable to the CPU's strong benchmark scores and the GPU's high throughput, which are discussed in the next section. The data confirms that users of this combo are getting a system that outperforms the vast majority of other tested configurations in Doom.

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

The NVIDIA GeForce RTX 4080 SUPER is the primary driver of frame rates in this pairing, especially at higher resolutions. It comes equipped with 16 GB of GDDR6X memory on a 256-bit bus, providing a memory bandwidth of 736.3 GB/s. This large memory pool and high bandwidth ensure that the GPU can handle high-resolution textures and complex scenes without running out of memory or experiencing bandwidth limitations. The GPU's boost clock of 2550 MHz, combined with its 10240 shading units, gives it a raw compute performance of 52.22 TFLOPS, which is more than sufficient for the demands of Doom.

The GPU's benchmark results reinforce its high-end status. It scores 34245 in the Passmark G3D test and 246994 in Geekbench OpenCL, placing it in the 88th percentile of all GPUs. Its average benchmark score of 53610 is within 0.2% of the AMD Radeon RX 6900 XT and 2.9% of the NVIDIA GeForce RTX 5070 Ti, showing that it is a direct competitor to other flagship cards. In game, the GPU's performance is the limiting factor at 4K, where the frame rates are the lowest. This is expected, as the GPU must render significantly more pixels at 3840x2160 than at 1920x1080. The GPU's 16 GB of VRAM is a future-proofing asset, ensuring that it can handle the most demanding textures without exceeding its memory capacity.

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

The measured FPS data shows a clear and expected trend: performance decreases as resolution increases. At 1920x1080 with Ultra settings, the average FPS is 239.9. Moving to 2560x1440 with the same settings drops the average to 152.4 FPS, a decrease of 87.5 FPS. At 3840x2160 with Ultra settings, the average falls further to 83.9 FPS, which is a 156.0 FPS drop from the 1080p result. This pattern is consistent across all settings, indicating that the GPU is the primary limiting factor at higher resolutions.

The scaling from 1440p to 4K is particularly steep. For High settings, the FPS drops from 189.8 at 1440p to 101.8 at 4K, a 46.4% reduction. This significant drop highlights that the GPU is working much harder to fill the additional pixels. In contrast, the scaling from 1080p to 1440p is less severe. For High settings, the FPS goes from 291.8 to 189.8, a 35.0% reduction. This suggests that at 1080p, the system is starting to become more CPU-bound, as the GPU has more headroom and is waiting for the CPU to send it data. The fact that the FPS at 1080p Low is 395.7, which is over 200 FPS higher than the 1080p Ultra result, further supports this, showing that the CPU can push out a massive number of frames when the GPU is not heavily loaded.

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

The measured FPS data provides a complete picture of performance across three resolutions and four settings presets. At 1920x1080, the system is exceptionally fast. With Low settings, it averages 395.7 FPS. Moving to Medium settings, the average drops to 347.9 FPS. High settings yield 291.8 FPS, and Ultra settings produce 239.9 FPS. These numbers show that even at the highest settings, the system is well above the refresh rate of most high-end monitors.

At 2560x1440, the performance remains very high. The Low preset averages 258.5 FPS, which is a significant drop from the 1080p result but still a very high frame rate. Medium settings average 224.5 FPS, High settings average 189.8 FPS, and Ultra settings average 152.4 FPS. The 1440p results show that the system can easily handle high-refresh-rate gaming at this resolution, with all presets delivering frame rates above 150 FPS. At 3840x2160, the performance is more demanding. Low settings average 142.2 FPS, which is still very playable. Medium settings average 124.3 FPS, High settings average 101.8 FPS, and Ultra settings average 83.9 FPS. The 4K results show that for a locked 144 FPS experience, users will need to use lower settings, but for a 60 FPS experience, even Ultra settings are viable.

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

Based on the measured data, the best experience depends on the user's target resolution and refresh rate. For 1080p and 1440p gaming, the Ultra preset is the clear recommendation. At 1080p, Ultra still delivers 239.9 FPS, which is far beyond the refresh rate of any standard monitor. At 1440p, Ultra delivers 152.4 FPS, which is excellent for high-refresh-rate displays, and the visual quality improvement over High settings is worth the small performance cost.

For 4K gaming, the recommendation is more nuanced. If the goal is to hit 120 FPS, the Medium preset, which averages 124.3 FPS, is the best choice. It provides a good balance of visual quality and performance. If the user has a 60 Hz display, the Ultra preset at 83.9 FPS is the best option, as it provides the highest visual quality while still maintaining a smooth frame rate. The High preset at 101.8 FPS is a middle ground, offering a higher frame rate than Ultra but with slightly reduced visual quality. For competitive play at 4K, the Low preset at 142.2 FPS is the best option, as it provides the highest frame rate and reduces input lag. Overall, the data shows that this system is versatile, and the best settings are dictated by the user's performance and quality priorities.
