Resolution Scaling

The frame rate drop from 1080p to 4K is dramatic and tells a clear story about component roles. At 1920x1080 with High settings, the combo produces 388.6 FPS. Moving to 2560x1440, that number falls to 256.4 FPS, a decrease of 132.2 FPS. The most significant drop occurs when moving to 3840x2160, where the average FPS plummets to 148, a further decline of 108.4 FPS.

This pattern is consistent across all settings. For instance, with Ultra settings, the FPS goes from 314 at 1080p to 212.9 at 1440p, and finally to 119.1 at 4K. The scaling from 1440p to 4K represents a much larger percentage drop than from 1080p to 1440p. This is a classic sign of the GPU becoming the dominant bottleneck at higher resolutions.

The implications are clear. At 1080p, the RTX 3080 is powerful enough to render frames far faster than the CPU can issue draw calls, making the processor the limiting factor. As resolution increases, the GPU's workload expands significantly, shifting the bottleneck back to the graphics card. The data shows a system that is exceptionally well-balanced for high-refresh-rate 1440p gaming, but at 4K, the GPU's limits are exposed.

Settings Recommendations

The measured data suggests that for the best balance of visual quality and frame rate, the High preset is the most logical choice. At 3840x2160, High settings deliver 148 FPS, which is a substantial 28.9 FPS improvement over Ultra (119.1 FPS) while likely offering a visually similar experience. The gap between High and Medium at 4K is also notable, with High being 20.1 FPS faster.

At 2560x1440, the High preset provides 256.4 FPS. This is an excellent result for a high-refresh-rate monitor, as it exceeds the 240Hz mark. While Ultra offers 212.9 FPS, the performance gain from High to Ultra is relatively small compared to the difference between High and Medium (294.2 FPS). The data indicates that Ultra may be a demanding preset that does not proportionally reward the user with extra frame rates.

For 1920x1080, even the most demanding Ultra preset delivers an exceptional 314 FPS. However, the data shows a significant performance cliff. High settings yield 388.6 FPS, while Medium provides 438.4 FPS. Given the extreme frame rates already on offer, the recommendation is to prioritize visual fidelity. High settings at 1080p provide a massive 74.6 FPS advantage over Ultra, making it a more sensible choice for consistent high-refresh-rate gameplay.

Measured FPS Breakdown

At 1920x1080, the system shows remarkable strength. With Low settings, it achieves an average of 482.5 FPS. Moving to Medium, the average drops to 438.4 FPS. High settings produce a still-massive 388.6 FPS. The Ultra preset is the most demanding, averaging 314 FPS.

At 2560x1440, the performance remains very high. Low settings average 322.5 FPS. Medium settings follow at 294.2 FPS. High settings deliver 256.4 FPS. The Ultra preset, while still fast, averages 212.9 FPS, which is the first time the average dips below the 240 FPS threshold.

At 3840x2160, the GPU workload becomes apparent. Low settings average 181.6 FPS. Medium settings increase the workload, bringing the average down to 168.1 FPS. High settings maintain a playable 148 FPS. The Ultra preset is the most taxing, resulting in an average of 119.1 FPS. This represents a 62.5 FPS difference between the lowest and highest quality settings at 4K.

CPU Role

The AMD Ryzen 7 5800X is an 8-core, 16-thread processor based on the Zen 3 architecture. Its 3.80 GHz base clock and 4.70 GHz boost clock are key to its performance. The processor's 32 MB of L3 cache and 7 nm process node contribute to its efficiency. This is a highly capable desktop CPU, as evidenced by its 84th percentile ranking among all CPUs.

In Roblox, the CPU's role is to manage game logic, physics, and draw calls. The benchmark results indicate that the 5800X is a powerful performer. Its Cinebench R23 multicore score is 23571, and its single-core score is 3327. The strong single-thread performance is crucial for games.

However, the measured FPS data suggests that this CPU becomes the limiting factor at lower resolutions. At 1080p, the frame rates are exceptionally high, but the scaling from Low to Ultra settings shows a clear pattern. The difference in FPS between these settings is likely due to the CPU's ability to process the increased draw calls and game logic, not the GPU's rendering speed. The 3dmark single-thread score of 943 and the Geekbench single-core score of 2194 confirm the processor's strong single-threaded capabilities, which are being fully utilized to push frames beyond what the GPU can render at lower resolutions.

GPU Role

The NVIDIA GeForce RTX 3080 is a high-end graphics card built on the Ampere architecture. It features 10 GB of GDDR6X memory on a 320-bit bus, providing 760.3 GB/s of bandwidth. Its base clock is 1440 MHz with a boost clock of 1710 MHz. The card's 8704 shading units and 68 RT cores give it immense raw power, placing it in the 80th percentile of all GPUs.

The GPU's role in Roblox becomes more significant as resolution increases. At 3840x2160, the frame rate drops from 181.6 FPS on Low to 119.1 FPS on Ultra. This 34% performance penalty shows that the GPU is being heavily taxed. The card's memory bandwidth is likely being saturated at 4K, which is a common bottleneck for high-resolution textures and effects.

The data shows that while the RTX 3080 is powerful, it cannot maintain the same extreme frame rates at 4K that the CPU can at 1080p. Its performance scaling from Low to Ultra at 4K is much more pronounced than at 1080p. This confirms that the RTX 3080 is the limiting component at the highest resolution, and its 10 GB VRAM and overall compute capacity define the performance ceiling in that scenario. The GPU's Passmark G3D score of 25086 and Geekbench Vulkan score of 145176 reflect its strengths, but the 4K results show the physical limits of the card.
