Doom

The AMD Ryzen 7 5800XT paired with the NVIDIA GeForce RTX 3080 Ti delivers a formidable Doom experience, securing a rank of 432 out of 1,681 tested combos. This places the pairing comfortably in the top quarter of all configurations, underscoring its ability to drive high frame rates in this title. The data indicates that this system is built for high-refresh-rate domination, though the specific performance ceiling shifts dramatically depending on resolution and quality presets.

How This Combo Ranks

In the broader context of all tested CPU-GPU pairings, this combination’s rank of 432 out of 1,681 combos places it in the 74th percentile of all tested configurations. This is a strong showing, but it is not a top-tier, halo result; it suggests a balanced system that excels at high-resolution gaming but is not the absolute fastest for esports-level 1080p play. The ranking reflects a synergy where neither component is a severe bottleneck, but where the GPU’s limitations become apparent at the highest settings. The data shows that this combo outperforms roughly three-quarters of all tested systems, making it a highly capable and reliable choice for this specific game.

CPU Role

The AMD Ryzen 7 5800XT is an 8-core, 16-thread processor based on the Zen 3 architecture, running on the AMD Socket AM4 platform. Its base clock is 3.80 GHz, which can boost up to 4.80 GHz, providing ample single-thread and multi-thread headroom. In Doom, which is a fast-paced FPS that benefits significantly from high single-core performance, this CPU’s capabilities are more than sufficient to keep up with the GPU. The processor’s strong single-thread score of 959 in the 3DMark single-thread test and 3,359 in Cinebench R23 single-core suggest that it can feed frames to the GPU without becoming a limiting factor at most settings.

However, the CPU’s role becomes more nuanced at lower resolutions and settings where the GPU is less stressed. The benchmark results show that at 1080p Low, the system achieves 315 FPS, which is an extremely high frame rate that demands significant CPU work to process game logic and draw calls. Given that the CPU’s average benchmark score is 29,774, placing it in the 86th percentile of all CPUs, it is clearly a capable processor. Its nearest rivals, such as the AMD Ryzen 7 6800HS and AMD Ryzen 7 7840H, have nearly identical average scores (within 0.3%), indicating that the 5800XT is competitively positioned in its class. While the 8 cores are not fully utilized by Doom’s engine, the high boost clock ensures that the game’s primary thread is processed with minimal delay, allowing the graphics card to operate at its full potential.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the dominant component in this pairing. Built on the Ampere architecture, this GPU features 12 GB of GDDR6X memory on a 384-bit bus, delivering a massive memory bandwidth of 912.4 GB/s. This high bandwidth is critical for feeding the GPU’s 10,240 shading units at high resolutions. The GPU’s boost clock of 1665 MHz allows it to achieve a pixel rate of 186.5 GPixel/s and a texture rate of 532.8 GTexel/s. In Doom, which is known for its detailed textures and fast-moving environments, these specifications translate directly into high and stable frame rates.

The GPU’s performance percentile of 83% and its average benchmark score of 41,224 place it just behind the NVIDIA GeForce RTX 3090, which scores 41,441 (a delta of -0.5%). This indicates that the 3080 Ti is a high-end part that offers near-flagship performance. The data shows that the GPU is the primary driver of performance at higher resolutions. For instance, at 4K Ultra, the frame rate is 67.7 FPS, while at 1080p Ultra, it jumps to 186.3 FPS. This scaling is typical of a GPU-bound scenario, where the graphics card’s processing power becomes the bottleneck as pixel count increases.

Measured FPS Breakdown

The measured FPS data reveals a clear performance hierarchy across resolutions and settings. At 1080p, the system is exceptionally fast. On Low settings, it hits an average of 315 FPS, which drops to 231.6 FPS on High and further to 186.3 FPS on Ultra. The Medium preset offers a middle ground at 270.6 FPS. Stepping up to 1440p, the performance remains impressive. The Low preset yields 202.6 FPS, while High and Medium produce 150.9 FPS and 179.4 FPS, respectively. The Ultra preset at 1440p averages 124.8 FPS.

At 4K, the system shows its limits. The Low preset manages 107.8 FPS, while Medium drops to 94.2 FPS and High to 83.2 FPS. The most demanding scenario, 4K Ultra, produces an average of 67.7 FPS. This data shows that the combo is most effective at 1080p and 1440p, where it can easily drive high-refresh-rate monitors. At 4K, the system is still very playable, but the user must be willing to dial back settings to maintain frame rates above 100 FPS. The difference between Low and Ultra at 4K is 40.1 FPS, illustrating the significant impact of graphical fidelity on this GPU.

Resolution Scaling

The frame rate scaling from 1080p to 4K is the most telling indicator of which component is the limiting factor. At Low settings, the frame rate drops from 315 FPS at 1080p to 202.6 FPS at 1440p (a 35.7% reduction) and then to 107.8 FPS at 4K (a 46.8% reduction from 1440p). This steep decline is a classic sign of a GPU-bound workload. At 1080p Low, the CPU is likely able to keep up with the GPU’s output, but as the resolution increases, the GPU’s rendering workload grows exponentially, causing the frame rate to plummet.

This pattern is even more pronounced at Ultra settings. The frame rate drops from 186.3 FPS at 1080p to 124.8 FPS at 1440p (a 33% reduction) and then to 67.7 FPS at 4K (a 45.8% reduction from 1440p). The fact that the percentage drop is relatively consistent across settings suggests that the GPU is the persistent bottleneck. The CPU’s high single-thread performance is sufficient to avoid becoming a limiting factor until the frame rate reaches extremely high levels, such as the 315 FPS seen at 1080p Low. In this specific scenario, the CPU’s 3.80 GHz base clock and 4.80 GHz boost clock are adequate to push the GPU to its maximum output, but the GPU’s raw processing power is ultimately what dictates the performance ceiling at higher resolutions. The data clearly indicates that for this game, the RTX 3080 Ti’s 12 GB of VRAM and 912.4 GB/s bandwidth are the key determinants of scaling, making this combo a 1440p champion and a capable 4K performer.
