Doom

# Resolution Scaling

The measured FPS data for Doom with the AMD Ryzen 7 5800X3D and NVIDIA GeForce RTX 4070 Ti reveals a clear pattern of performance scaling across resolutions. At 1080p, the combo delivers extremely high frame rates, with the Low preset reaching 338.5 FPS and Medium hitting 320 FPS. The High preset achieves 273.7 FPS, while Ultra drops to 224.9 FPS. These numbers indicate that at 1080p, the system is operating well beyond typical display refresh rates, suggesting the CPU and GPU combination has substantial headroom.

Moving to 1440p, the frame rates remain very strong but show the expected decline from 1080p. The Low preset produces 239.1 FPS, Medium delivers 209.9 FPS, and High reaches 176.2 FPS. The Ultra preset at 1440p yields 142.7 FPS. The percentage drop from 1080p to 1440p is relatively modest across all settings, with the Low preset falling by approximately 29% and the High preset by about 36%. This moderate reduction indicates that the RTX 4070 Ti is still comfortably managing the increased pixel count without becoming the dominant bottleneck.

At 4K (3840x2160), the scaling becomes more pronounced. The Low preset drops to 131.2 FPS, Medium to 109.4 FPS, and High to 97.2 FPS. The Ultra preset falls to 79.1 FPS. Comparing 1440p to 4K, the Low preset loses about 45% of its performance, while the High preset loses roughly 45% as well. This consistent proportional decline across resolutions strongly suggests that the GPU is becoming the primary limiting factor at 4K, as the pixel workload increases by a factor of 2.25 from 1440p to 4K, and the frame rate reductions align closely with that scaling.

The data indicates a smooth, predictable scaling curve. At 1080p, the system achieves frame rates that are likely CPU-limited in some scenarios, particularly at Low settings where 338.5 FPS approaches the upper bounds of what even a high-end processor can sustain. The Ryzen 7 5800X3D, with its 8 cores and 16 threads, provides sufficient single-thread performance to feed the GPU at these extreme frame rates. However, as resolution increases, the GPU workload grows, and the RTX 4070 Ti's performance characteristics become the determining factor.

Notably, the gap between Low and Ultra settings widens as resolution increases. At 1080p, the difference between Low and Ultra is 113.6 FPS (338.5 versus 224.9). At 1440p, that gap narrows to 96.4 FPS (239.1 versus 142.7). At 4K, the difference shrinks further to 52.1 FPS (131.2 versus 79.1). This narrowing gap indicates that at higher resolutions, the GPU is working closer to its limits, and the performance cost of higher quality settings becomes relatively smaller in absolute terms but still significant.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on the target resolution and display refresh rate. At 1080p, all presets deliver exceptionally high frame rates, with even the Ultra preset maintaining 224.9 FPS. For gamers with 144Hz or 240Hz displays at 1080p, the Ultra preset provides the best visual quality while still exceeding 200 FPS, making it the recommended choice. The High preset at 273.7 FPS offers a modest performance increase but sacrifices some visual fidelity.

At 1440p, the High preset delivers 176.2 FPS, which comfortably exceeds 144Hz refresh rates while maintaining strong visual quality. The Ultra preset at 142.7 FPS is close to the 144Hz threshold but falls slightly short. For users with 144Hz displays, High is the recommended preset, as it provides a 33.5 FPS buffer over Ultra while still looking excellent. Those with 165Hz or higher refresh rate monitors may need to consider the Medium preset at 209.9 FPS, though this involves a noticeable visual downgrade from High.

At 4K, the choice becomes more constrained. The High preset at 97.2 FPS is the highest quality setting that remains above 60 FPS, making it the recommended choice for 4K gaming. The Ultra preset at 79.1 FPS is still playable and may appeal to users prioritizing visual quality over frame rate, but the 18.1 FPS drop from High is substantial. The Medium preset at 109.4 FPS offers a good middle ground for those wanting higher frame rates at 4K, while the Low preset at 131.2 FPS provides the smoothest experience but with significant visual compromises.

The data suggests that the High preset represents the best balance of visual quality and performance across all three resolutions. It maintains high frame rates at 1080p and 1440p, and remains playable at 4K. The Ultra preset is viable at 1080p and 1440p, but at 4K it pushes the system to its limits with 79.1 FPS. For users with variable refresh rate displays, the frame rates across all presets are high enough to minimize tearing and stuttering, making the choice primarily about visual preference versus frame rate headroom.

How This Combo Ranks

The AMD Ryzen 7 5800X3D paired with the NVIDIA GeForce RTX 4070 Ti achieves a combo rank of 234 out of 1681 tested combinations in Doom. This places the system in the top 14% of all tested configurations, indicating strong overall performance for this specific game. Given that Doom is a fast-paced FPS that benefits from high frame rates, this ranking reflects the combo's ability to deliver excellent performance across the measured resolutions.

The CPU's individual performance metrics support this strong showing. The Ryzen 7 5800X3D has an average benchmark score of 26574, placing it in the 83rd percentile among all CPUs. Its nearest rivals include the AMD EPYC 8024P with a score of 26555 (0.1% difference), the Intel Core i9-11900K at 26546 (0.1% difference), and the AMD Ryzen 5 7600 at 26617 (-0.2% difference). These close scores indicate that the 5800X3D is competitive with other high-end processors, though not a class leader.

The GPU also performs well relative to its peers. The RTX 4070 Ti has an average benchmark score of 44900, placing it in the 85th percentile among all GPUs. Its nearest rivals include the NVIDIA GeForce RTX 5090 Mobile at 45152 (-0.6% difference), the Intel Arc A730M at 45592 (-1.5% difference), and the AMD Radeon Pro 580 at 44195 (1.6% difference). The RTX 4070 Ti's competitive positioning contributes to the combo's strong ranking.

The combination of a top-quartile CPU and GPU results in a system that ranks well in Doom specifically. The game's optimization for high frame rates and its relatively modest system requirements compared to modern AAA titles allow this combo to excel. The rank of 234 out of 1681 suggests that while many higher-end configurations exist, this pairing delivers performance that surpasses the vast majority of tested systems.

CPU Role

The AMD Ryzen 7 5800X3D features 8 cores and 16 threads based on the Zen 3 architecture, manufactured on TSMC's 7 nm process node. Its base clock is 3.40 GHz with a boost clock of 4.50 GHz, and it includes 96 MB of shared L3 cache. This large cache is a defining characteristic of the 5800X3D and contributes to its gaming performance by reducing memory latency in cache-sensitive workloads.

In Doom, the CPU's role is primarily to feed the GPU with sufficient draw calls and game logic updates. The measured frame rates at 1080p, particularly at Low settings where the GPU workload is lighter, reach up to 338.5 FPS. At these frame rates, the CPU's single-thread performance becomes increasingly important. The 5800X3D's boost clock of 4.50 GHz and its large L3 cache help maintain high minimum frame rates and reduce stuttering in scenes with complex geometry.

The CPU's multi-threaded performance, as measured by benchmarks like Cinebench R23 (24063 multicore, 3397 singlecore), indicates strong overall capability. However, in Doom, the game's engine typically scales well with both single-core and multi-core performance. The 16 threads allow the game to distribute workloads across multiple cores, while the 96 MB L3 cache helps keep frequently accessed data close to the processing cores.

The CPU's benchmark scores show a clear progression from single-threaded to multi-threaded workloads. The 3DMark single-thread score of 884 and 2-thread score of 1746 demonstrate solid per-core performance, while the 8-thread score of 5906 and max-thread score of 7285 indicate good scaling across cores. This balanced performance profile is well-suited for a game like Doom, which can utilize multiple threads for rendering and physics calculations.

The Ryzen 7 5800X3D's 105 W TDP and end-of-life production status suggest it is a mature product that has been superseded by newer generations. However, its combination of 8 cores, high boost clock, and large cache ensures it remains capable for gaming workloads. In this specific combo, the CPU does not appear to be the primary bottleneck at higher resolutions, as the frame rate scaling from 1440p to 4K aligns closely with the GPU's expected performance curve.
