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 74 FPS. At 1440p, frame rates range from 57 to 66 FPS. At 4K, frame rates range from 42 to 55 FPS.
The RTX PRO 500 Blackwell Mobile is 227% above the recommended GPU (GeForce GTX 660) for Roblox. The Ryzen 7 7800X3D is 1465% above the recommended CPU (Core 2 Duo).
The RTX PRO 500 Blackwell Mobile sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the Ryzen 7 7800X3D still has additional frame-generation headroom.
This chart answers a simple question: which upgrade is more likely to increase FPS first? In this case, the answer is clearly the GPU.
The largest gap appears at 1080p Medium, where the RTX PRO 500 Blackwell Mobile reaches about 95 FPS, while the Ryzen 7 7800X3D still has headroom up to roughly 648 FPS.
That means the RTX PRO 500 Blackwell Mobile is hitting its performance ceiling first, leaving a 85% gap versus the Ryzen 7 7800X3D's available headroom in the most unbalanced scenario. Across all tested settings, this pairing is GPU-limited in 12 out of 12 cases, with 0 CPU-limited and 0 balanced results.
Overall, this is a clearly GPU-bound combination in this game.
The RTX PRO 500 Blackwell Mobile is consistently the limiting part in this game, so upgrading the GPU is more likely to deliver a larger FPS gain than upgrading the CPU.
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 7800X3D with GeForce RTX 5090, our current GPU anchor. To estimate the GPU ceiling, we pair the RTX PRO 500 Blackwell Mobile 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 7800X3D paired with the RTX PRO 500 Blackwell Mobile can run Roblox smoothly up to 1080p achieving around 74 FPS at Ultra quality. Your GPU is 227% above the recommended specs, and your CPU is 1465% 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.
For Roblox, upgrading the GPU would usually give you the most noticeable improvement. In the Performance Limiter Analysis, the RTX PRO 500 Blackwell Mobile is the side that most often caps the frame rate, while the Ryzen 7 7800X3D still has additional headroom in the tested presets. The main bottleneck appears on the GPU side. The largest gap shows up at 1080p Medium, where the GPU reaches about 95 FPS while the CPU still has headroom up to roughly 648 FPS. Across all tested settings, the distribution is 12/12 GPU-limited, 0/12 CPU-limited, and 0/12 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 7800X3D and RTX PRO 500 Blackwell Mobile 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.
