Doom

The pairing of AMD’s Ryzen 5 5500X3D with NVIDIA’s GeForce RTX 4080 produces a fascinating dataset in Doom, one that reveals a clear division of labor between the processor and the graphics card. The measured frames per second (FPS) across resolutions and settings tell a story of a GPU that is powerful enough to dominate at lower resolutions, yet still finds itself the primary constraint at 4K. This analysis breaks down those numbers, examines what they mean for the user, and places the combination within the broader context of other tested hardware.

Resolution Scaling

The most striking observation in the data is how average FPS scales with resolution. At 1080p, the combo is exceptionally fast, with the Low preset hitting 306 FPS and even the demanding Ultra preset managing 241 FPS. Moving to 1440p, we see a predictable drop, with the High preset falling from 275 FPS to 191 FPS, a decrease of roughly 30%. This pattern indicates that at these lower resolutions, the system is likely not being pushed to its absolute limit by the GPU, as the frame rates are so high that they suggest a degree of headroom.

However, the transition to 4K (3840x2160) reveals a more significant shift. The High preset at 4K yields 104 FPS, which is a 45% reduction from the 1440p High score. This substantial drop points directly to the GPU becoming the limiting factor. The rendering load at 4K is immense, and the RTX 4080, despite its power, is now the bottleneck. This is a classic indicator: when FPS drops proportionally more than the pixel count increases, the graphics card is saturated. The data shows this clearly, as the scaling from 1440p to 4K is much more punishing than the scaling from 1080p to 1440p.

The data suggests that the CPU has less influence on performance as resolution increases. At 1080p, the processor's ability to feed the GPU is crucial for hitting those high triple-digit frame rates. But by 4K, the GPU is working so hard that the CPU’s role diminishes, and the measured FPS becomes a more direct reflection of the graphics card's raw compute power. The 141 FPS at 4K Low versus the 306 FPS at 1080p Low highlights this, as the gap is not just about resolution, but about where the performance ceiling is located. The game is clearly more demanding on the GPU at higher resolutions, and the CPU's high core count and large cache are less relevant when the GPU is spending most of its time on pixel work.

Settings Recommendations

The measured rows provide a clear hierarchy of performance for each settings preset. At 1080p, the jump from Low to Ultra is relatively small in percentage terms, but the absolute numbers are still high. The Ultra preset at 1080p delivers 241 FPS, which is a fantastic experience on a high-refresh-rate monitor. The data implies that at 1080p, users can comfortably max out the settings without worrying about performance degradation, as even the most demanding preset offers a very high frame rate.

At 1440p, the story is similar, but the margins tighten. The High preset delivers 191 FPS, while Ultra drops to 156 FPS. The difference between High and Ultra is a 35 FPS loss, which could be noticeable to a discerning eye. However, both scores are well above the 144 FPS threshold for high-refresh-rate gaming. The data suggests that High is the sweet spot for 1440p, balancing visual fidelity with a very high performance ceiling. Choosing Ultra is still a viable option, but the measured data indicates a diminishing return for the extra GPU load.

The 4K resolution is where the recommendation becomes more nuanced. The High preset at 4K produces 104 FPS, which is excellent for 4K gaming, but the Ultra preset drops to 85 FPS. This 19 FPS difference is more significant at 4K, where the frame rate is already lower. For users with a 60 Hz or 120 Hz 4K display, the High preset seems ideal, as it provides a comfortable margin above 60 FPS and is only a modest step down from the visual quality of Ultra. The Low preset at 4K (141 FPS) is an outlier, suggesting that if a user prioritizes frame rate above all else, the game can be made to run incredibly fast even at this high resolution, but the graphical compromise would be substantial.

GPU Role

The NVIDIA GeForce RTX 4080 is the undeniable star of this configuration for raw frame rate. Its 16 GB of GDDR6X memory on a 256-bit bus provides a bandwidth of 716.8 GB/s, which is a critical asset for a game like Doom that can be sensitive to texture loading and memory throughput at high resolutions. The data shows that the GPU is capable of pushing over 300 FPS at 1080p Low, demonstrating immense headroom that is likely not fully utilized by most displays.

The GPU’s clock speeds, with a base of 2205 MHz and a boost of 2505 MHz, are robust and contribute to its high performance. The benchmark results for the GPU are also telling. A Passmark G3D score of 34457 and a Geekbench Vulkan score of 263779 place it in the top tier of graphics cards. Its nearest rivals are the RTX 4080 SUPER, which scores a 0.1% delta, and the AMD Radeon Pro W5700X, which is -1.1% slower. This suggests that the RTX 4080 is performing exactly as expected, with a negligible difference from its direct successor.

The VRAM capacity of 16 GB is a forward-looking feature. While Doom may not currently require that much memory, the data indicates that the card has ample resources to handle high-resolution textures and future content without running into memory limitations. The 4K Ultra preset, which would be the most demanding on memory, still maintains an average of 85 FPS, suggesting that the 16 GB pool is not a bottleneck in this specific title. The GPU's role is clear: it is the primary driver of performance, especially as resolution scales, and its specifications align well with the measured results.

Measured FPS Breakdown

Delving into the specific numbers, the data provides a detailed picture of performance across all settings. At 1920x1080, the Low preset achieves an average of 306 FPS, with the Medium preset slightly lower at 292 FPS. The High preset produces 275 FPS, and the Ultra preset brings up the rear at 241 FPS. The 1080p Medium preset also shows a minimum of 248 FPS and a maximum of 336 FPS, indicating some variance but maintaining a high floor.

At 2560x1440, the Low preset hits 260 FPS, while the Medium preset delivers 226 FPS, with a minimum of 192 FPS and a maximum of 260 FPS. The High preset achieves 191 FPS, and the Ultra preset drops to 156 FPS. The scaling here is consistent, with each step up in settings costing a roughly 30-35 FPS.

The 3840x2160 results show the most significant impact from settings. The Low preset is the highest at 141 FPS, followed by the Medium preset at 123 FPS, which has a minimum of 104 FPS and a maximum of 141 FPS. The High preset is next at 104 FPS, and the Ultra preset is the lowest at 85 FPS. This breakdown highlights that at 4K, the choice of settings has a more pronounced effect on the final frame rate than at lower resolutions, as the GPU is working closer to its maximum capacity.

How This Combo Ranks

The combination of the Ryzen 5 5500X3D and RTX 4080 has a combo rank of 391 out of 3712 tested combinations in Doom. This places it in the top 10.5% of all tested systems, which is a strong showing. The percentile data for the individual components reinforces this. The CPU is in the 85th percentile of all CPUs, and the GPU is in the 86th percentile of all GPUs. This suggests a well-balanced pairing, where neither component is severely holding back the other.

However, the rank also indicates that there is a significant amount of performance above this combo. The top 390 combinations are likely to feature more powerful CPUs or higher-end GPUs, such as the RTX 4090 or newer generations. The deltaPct values for the GPU's rivals show that the RTX 4080 is very close in performance to the RTX 4080 SUPER (0.1% faster), which means a combo with that card would likely rank slightly higher. The data suggests that this is a high-performance setup, but not the absolute pinnacle. The rank of 391 reflects the raw power of the RTX 4080, but it also shows that the CPU, while excellent, is not the top-tier option for those chasing the absolute highest frame rates in this specific, well-optimized title.

CPU Role

The AMD Ryzen 5 5500X3D plays a supporting role, but its characteristics are crucial for maintaining high minimum frame rates and ensuring the GPU isn't starved of data. With 6 cores and 12 threads based on the Zen 3 architecture, it's a modern, capable processor. Its defining feature is the 96 MB of shared L3 cache, which is massive and helps in gaming scenarios by storing more frequently accessed data. The benchmark data reflects a well-rounded processor, with a Passmark single-thread score of 2941 and a multithread score of 20363.

The CPU's nearest rivals show it's in a tight competitive cluster. The AMD Ryzen 5 5600F scores 0.2% higher, while the AMD Ryzen AI 7 PRO 450 is -0.2% lower. The Intel Core i9-12900T is -0.3% lower, and the Intel Core Ultra 5 225 is 0.2% higher. This indicates that the 5500X3D is performing at a level comparable to these other mid-range and high-end processors, with no significant performance gap. The deltaPct values are all within a fraction of a percent, suggesting that in this game, the CPU is not the primary differentiator in the final FPS count.

The data implies that the CPU's role is to ensure the GPU can reach its full potential. At 1080p, where the GPU is less stressed, the CPU's strong single-thread performance and large cache likely help achieve those very high frame rates. However, as the resolution increases, the GPU becomes the bottleneck, and the CPU's influence on the average FPS diminishes. The CPU is not a weak link; it is a competent partner that provides a solid foundation for the RTX 4080 to excel, but it is the GPU that ultimately dictates the high scores in the resolution scaling analysis.
