Roblox
Scales from mobile devices to high-end PCs. The engine is lightweight and typically capped at 60 FPS. It requires a stable internet connection for asset streaming and a DX10 compatible GPU.
This game has a built-in FPS cap of 60 FPS
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 440 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 225 FPS. At 4K, all settings exceed 200 FPS.
The GeForce RTX 4090 is 843% above the recommended GPU (GeForce GTX 660) for Roblox. The Ryzen 7 5800HS is 791% above the recommended CPU (Core 2 Duo).
At lower resolutions (1080p (low/medium/high)), the Ryzen 7 5800HS sets the FPS ceiling. As graphical load increases at (all 4k settings), the GeForce RTX 4090 becomes the FPS-limiting side. The FPS ceiling is closely matched at 1080p ultra, all 1440p settings.
This chart answers a simple question: which upgrade is more likely to increase FPS first? In this case, the answer is more often the GPU.
The largest gap appears at 4K Low, where the GeForce RTX 4090 reaches about 294 FPS, while the Ryzen 7 5800HS still has headroom up to roughly 318 FPS.
That means the GeForce RTX 4090 is hitting its performance ceiling first, leaving a 8% gap versus the Ryzen 7 5800HS's available headroom in the most unbalanced scenario. Across all tested settings, this pairing is GPU-limited in 4 out of 12 cases, with 3 CPU-limited and 5 balanced results.
Overall, this is a GPU-leaning combination in this game.
The GeForce RTX 4090 is more often the limiting part in this game, so a GPU upgrade is somewhat more likely to deliver the bigger FPS gain than a CPU upgrade.
This chart shows which upgrade is more likely to unlock more FPS in each tested setting. The lower line represents the part that reaches its limit first. When the CPU and GPU lines stay close together, the system is more balanced. When the gap widens, one component is more clearly holding the other back. Hover any setting to inspect it.
The lower line is the current limiter. The closer the two lines are, the more balanced the CPU and GPU are for this game.
Each line represents an estimated FPS ceiling for one component, rather than live usage alone.
To estimate the CPU ceiling, we pair the Ryzen 7 5800HS with GeForce RTX 5090, our current GPU anchor. To estimate the GPU ceiling, we pair the GeForce RTX 4090 with Ryzen 9 9950X3D, our current CPU anchor.
The lower line indicates the current limiter, since that component reaches its FPS ceiling first. In most scenarios, that is also the part most likely to deliver the bigger performance uplift if upgraded first.
The percentage shown represents the gap between the two ceilings. In practical terms, it shows how much of the stronger component's potential is left unused because the weaker one becomes the bottleneck first.

Yes, the Ryzen 7 5800HS paired with the GeForce RTX 4090 can run Roblox smoothly up to 4k achieving around 200 FPS at Ultra quality. Your GPU is 843% above the recommended specs, and your CPU is 791% above the recommended requirements.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced - this ensures you're not overspending on one component that the other can't keep up with.
Your GeForce RTX 4090 is already a top-tier graphics card. In the Performance Limiter Analysis, it is still the side that most often reaches its FPS ceiling first, but there is no meaningful upgrade path that would drastically improve your Roblox performance right now. The main bottleneck appears on the GPU side. The largest gap shows up at 4K Low, where the GPU reaches about 294 FPS while the CPU still has headroom up to roughly 318 FPS. Across all tested settings, the distribution is 4/12 GPU-limited, 3/12 CPU-limited, and 5/12 balanced.
Roblox does not currently support Frame Generation technologies like DLSS 3 or FSR 3. Your performance is based entirely on native rendering. If the game adds support in a future update, newer GPUs will benefit the most.
Roblox requires at minimum a Celeron D (CPU) and GeForce 6600 (GPU) with 1 GB RAM and 20 MB storage. For the recommended experience, you need a Core 2 Duo and GeForce GTX 660 with 4 GB RAM. Your Ryzen 7 5800HS and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
These Roblox FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.
Performance estimates are based on synthetic benchmarks and hardware capabilities.
Results may vary based on drivers, OS, and background processes.
