Doom

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 3080 Ti delivers a decisive performance profile in Doom, a 2016 FPS known for its demanding Vulkan-based engine. The measured data shows this combination is heavily GPU-limited at higher resolutions, while the CPU’s strong single-threaded and multi-threaded capabilities ensure that even at 1080p, frame rates remain exceptionally high. This analysis breaks down the measured FPS, settings scaling, and component roles based solely on the provided metrics.

FAQ

Q: What is the highest average frame rate this combo achieves in Doom?

A: The highest recorded average is 311.1 FPS at 1920x1080 with Low settings. This drops to 186.7 FPS at the same resolution when set to Ultra, showing a significant impact from graphical presets.

Q: How does the combo perform at 4K with the Ultra preset?

A: At 3840x2160 with Ultra settings, the average FPS falls to 68.8. This is the lowest measured result in the dataset, indicating a substantial load on the GPU at this resolution and quality level.

Q: What is the frame rate difference between Low and High settings at 1440p?

A: At 2560x1440, Low settings produce an average of 203.1 FPS, while High settings produce 151.9 FPS. This represents a performance gap of 51.2 FPS between the two presets.

Q: Does the RTX 3080 Ti’s 12 GB VRAM appear to be a limiting factor in this game?

A: The data does not include VRAM usage metrics. However, the consistent frame rate scaling from 1080p to 4K suggests the GPU’s processing power, not memory capacity, is the primary constraint, as performance drops proportionally with resolution.

Q: How does this combo rank among all tested system combinations for this game?

A: The combo is ranked 447 out of 1681 tested combinations. This places it in the upper quartile, indicating it outperforms the majority of systems tested in this specific game.

Q: What is the average FPS at 1080p with Medium settings?

A: With Medium settings at 1920x1080, the measured average FPS is 273. This is higher than the High preset’s 231.4 FPS but lower than Low’s 311.1 FPS.

Settings Recommendations

For players targeting smooth gameplay on high-refresh-rate monitors, the measured data suggests that the Medium preset offers an optimal balance. At 1920x1080, Medium yields an average of 273 FPS, which is significantly higher than High’s 231.4 FPS and only 38 FPS below Low. The jump from Medium to High costs a substantial amount of performance, while the visual fidelity difference is often less critical in a fast-paced FPS.

At 2560x1440, the High preset is a strong contender, providing an average of 151.9 FPS. This is well above the 144 Hz threshold commonly targeted by gamers. However, the Ultra preset at this resolution drops to 119.9 FPS, which may still be acceptable but represents a clear trade-off. For 4K gaming, the High preset is recommended over Ultra, as it provides 82 FPS compared to 68.8 FPS, a difference that is more noticeable in fluidity than the visual upgrade from High to Ultra.

The Low preset is rarely necessary with this hardware, as even at 4K it maintains an average of 108.5 FPS. The data suggests that users can comfortably start at Medium or High and adjust based on their specific refresh rate and resolution priorities, as the GPU has enough headroom to avoid the lowest quality settings.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the dominant component in these results, particularly as resolution increases. Its 12 GB of GDDR6X memory on a 384-bit bus provides a memory bandwidth of 912.4 GB/s, which is ample for Doom’s textures at 4K. The GPU’s boost clock of 1665 MHz and 10240 shading units drive the heavy lifting for pixel and texture processing.

The data shows a clear GPU bottleneck at higher resolutions. Moving from 1080p to 4K at High settings reduces the average FPS from 231.4 to 82, a drop of 149.4 FPS. This scaling pattern is characteristic of a GPU-bound scenario, where the CPU has sufficient headroom to feed the graphics card. The GPU’s 34.10 TFLOPS FP32 performance is what allows for playable 4K frame rates, but the Ultra preset’s 68.8 FPS result indicates that even this powerful card struggles with the most demanding settings at that resolution.

The RTX 3080 Ti’s performance relative to its nearest rivals shows it is competitive, though slightly behind. It trails the RTX 3090 by 0.5% in average benchmark score, and the RTX 5070 by 1.1%. In Doom, this means the 3080 Ti should deliver frame rates very close to those of the RTX 3090, with the data confirming it is a high-end performer for this title.

Measured FPS Breakdown

At 1920x1080, the combo shows exceptional performance across all settings. Low settings produce 311.1 FPS, Medium 273 FPS, High 231.4 FPS, and Ultra 186.7 FPS. The scaling from Low to Ultra shows a total performance loss of 124.4 FPS, with the largest single drop occurring between Medium and High (41.6 FPS).

At 2560x1440, the same pattern persists but with reduced absolute numbers. Low settings yield 203.1 FPS, Medium 177.9 FPS, High 151.9 FPS, and Ultra 119.9 FPS. The drop from Medium to High here is 26 FPS, and from High to Ultra it is 32 FPS. The resolution increase from 1080p to 1440p costs roughly 35% of the frame rate at each settings level.

At 3840x2160, the GPU is clearly the limiting factor. Low settings manage 108.5 FPS, Medium 95.6 FPS, High 82 FPS, and Ultra 68.8 FPS. The difference between Low and Ultra at 4K is 39.7 FPS, which is proportionally similar to the drop seen at lower resolutions. The data shows that even at 4K, the Low preset is playable, but the Ultra preset pushes the hardware to its limits.

How This Combo Ranks

The AMD Ryzen 9 7900X and RTX 3080 Ti combination ranks 447th out of 1681 tested combos in Doom. This places it in the top 26.6% of all systems tested, which is a strong showing for a high-end desktop setup. The ranking reflects the GPU’s capability, as the CPU’s performance is sufficient to avoid becoming a bottleneck at most settings.

The CPU itself holds a 93rd percentile ranking among all CPUs, with an average benchmark score of 50556. Its nearest rivals include the Intel Core Ultra 5 235, which scores 50598 (a 0.1% difference), and the AMD Ryzen 9 5900XT at 50738 (0.4% higher). The small deltaPct values indicate that the 7900X is essentially on par with these competitors in synthetic tests. The GPU’s 83rd percentile ranking among all GPUs is slightly lower, but its 41224 average benchmark score is close to that of the RTX 3090 (41441). The combo’s mid-tier rank in-game suggests that while both components are individually strong, the specific demands of Doom favor systems with even faster GPUs.

CPU Role

The AMD Ryzen 9 7900X, with 12 cores and 24 threads, provides substantial multi-threaded throughput, as evidenced by its Cinebench R23 multicore score of 43695. However, in Doom, the CPU’s role is primarily about maintaining high single-threaded performance to feed the GPU. Its single-core Cinebench R23 score of 6168 and Geekbench single-core score of 2952 indicate strong per-core capability.

The CPU’s boost clock of 5.60 GHz and base clock of 4.70 GHz are key to its performance in this FPS. The data shows that at 1080p, the CPU is not a limiting factor, as frame rates exceed 300 FPS on Low settings. This indicates that the 7900X can keep up with the RTX 3080 Ti’s output at lower resolutions. At 4K, the CPU’s influence diminishes further, as the GPU becomes the primary constraint. The CPU’s 64 MB of shared L3 cache and 83.2 GB/s memory bandwidth also help reduce latency in game logic, but the measured FPS scaling suggests the CPU has ample headroom to avoid bottlenecking in this title.

Resolution Scaling

The FPS drop from 1080p to 4K is consistent across all settings, indicating a classic GPU-bound scaling pattern. At High settings, the average FPS falls from 231.4 at 1080p to 151.9 at 1440p, a 34.4% reduction, and then to 82 at 4K, a further 46% reduction. This shows that the GPU’s workload increases dramatically with resolution, while the CPU’s workload remains relatively static.

At Low settings, the scaling is similar: 311.1 FPS at 1080p drops to 203.1 at 1440p (a 34.7% drop) and then to 108.5 at 4K (a 46.6% drop). The consistent percentage drops across settings suggest that the limiting component is the GPU’s raw pixel-pushing capability, not any specific setting. The data implies that if the CPU were the bottleneck, the frame rates would not scale down so predictably with resolution. Instead, the 4K results show a GPU that is working near its maximum capacity, particularly at Ultra settings where it manages only 68.8 FPS. This resolution scaling analysis confirms that the RTX 3080 Ti is the component to upgrade for better 4K performance, while the Ryzen 9 7900X provides more than enough processing power for this game.
