At 1440p low, the Ryzen 5 3600 sets the ceiling at about 241 FPS, while the GeForce RTX 4090 could reach 345 FPS. In this scenario, the CPU limits the GPU potential by 30% (FPS gap: 104 FPS). Overall distribution: CPU limits 11/12 cells, GPU limits 0/12, balanced 1/12.
Your Ryzen 5 3600 is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 23% | CPU Limits GPU 18% | CPU Limits GPU 9% | Balanced |
| 1440p (2K QHD) | CPU Limits GPU 30% | CPU Limits GPU 30% | CPU Limits GPU 19% | CPU Limits GPU 15% |
| 4K (Ultra HD) | CPU Limits GPU 25% | CPU Limits GPU 23% | CPU Limits GPU 19% | CPU Limits GPU 14% |
We estimate the maximum FPS the processor can sustain and the maximum FPS the graphics card can sustain in each setting, then compare those limits directly.
Limit Factor formula: (stronger - weaker) / stronger. Example: if CPU ceiling is 200 FPS and GPU ceiling is 140 FPS, then GPU limits CPU by 30%.
CPU Limits GPU means the processor ceiling is lower. GPU Limits CPU means the graphics ceiling is lower. Balanced means the FPS ceilings are close enough that the gap is negligible.
The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

The Ryzen 5 3600 + GeForce RTX 4090 pairing runs this title with CPU utilization between 6% and 36% and GPU utilization between 14% and 56%. Ryzen 5 3600 keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 27% at 1080p to 40% at 4K, while CPU averages move from 21% to 22%.
Neither component is close to saturation: CPU tops out at 36% and GPU at 56%. This pattern suggests possible engine-side limits, an FPS cap, or workload constraints unrelated to raw hardware throughput.
At 1080p, averages sit around CPU 21% and GPU 27%. At 1440p, that shifts to CPU 21% and GPU 37%, and at 4K it reaches CPU 22% and GPU 40%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
4K (Ultra HD) High is the most balanced preset based on this dataset. It runs around CPU 24% (11-36%) and GPU 41% (26-56%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Ryzen 5 3600 remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Ryzen 5 3600 and GeForce RTX 4090 remain reasonably matched for this title.

Yes, the Ryzen 5 3600 paired with the GeForce RTX 4090 can run Roblox smoothly up to 4k achieving around 209 FPS at Ultra quality. Your GPU is 843% above the recommended specs, and your CPU is 707% above the recommended requirements.
This CPU + GPU combo costs approximately $1729 ($80 CPU (Rank #12 Value) + $1649 GPU (Rank #77 Value)). Your build is already very cost-efficient, but if you want even more FPS, the next good option is upgrading the CPU. For example, the Ryzen 9 9950X is a great upgrade option for around $649 (Rank #5 for value).
For Roblox, upgrading the CPU would have the biggest impact on performance. The Ryzen 5 3600 is currently the limiting factor — the GeForce RTX 4090 has extra headroom that a faster processor could take advantage of. This is especially noticeable at 1080p where CPU performance matters more. CPU-limited at: 1080p low, 1080p medium, 1080p high, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra.
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 5 3600 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.
