Performance Report
At 1080p, all quality settings exceed 258 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 218 FPS. At 4K, all settings exceed 222 FPS.
The GeForce RTX 4090 is 843% above the recommended GPU (GeForce GTX 660) for Roblox. The Ryzen 5 220 is 756% above the recommended CPU (Core 2 Duo).
At lower resolutions (1440p (medium/ultra)), the Ryzen 5 220 determines the performance ceiling. As graphical load increases at (1080p (low/medium/high), 4k (low/medium/high)), the GeForce RTX 4090 takes over as the primary performance factor. The system is well balanced at 1080p ultra, 1440p (low/high), 4k ultra.
Approximated average price on current market:
Combo price: $1799. At 1080p Ultra, this combo delivers 258 FPS, equivalent to 0.14 FPS per dollar.

At 1440p ultra, the Ryzen 5 220 sets the ceiling at about 222 FPS, while the GeForce RTX 4090 could reach 252 FPS. In this scenario, the CPU limits the GPU potential by 12% (FPS gap: 30 FPS). Overall distribution: CPU limits 3/12 cells, GPU limits 6/12, balanced 3/12.
The Ryzen 5 220 and GeForce RTX 4090 stay close in effective frame-generation ceiling across most presets, so neither side consistently suppresses the other by a large margin.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 6% | GPU Limits CPU 7% | GPU Limits CPU 6% | Balanced |
| 1440p (2K QHD) | Balanced | CPU Limits GPU 6% | CPU Limits GPU 6% | CPU Limits GPU 12% |
| 4K (Ultra HD) | GPU Limits CPU 7% | GPU Limits CPU 11% | GPU Limits CPU 11% | Balanced |
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.

Yes, the Ryzen 5 220 paired with the GeForce RTX 4090 can run Roblox smoothly up to 4k achieving around 222 FPS at Ultra quality. Your GPU is 843% above the recommended specs, and your CPU is 756% above the recommended requirements.
This CPU + GPU combo costs approximately $1799 ($150 CPU (Rank #15 Value) + $1649 GPU (Rank #77 Value)). Your GeForce RTX 4090 provides phenomenal top-tier performance but at a premium enthusiast price. Since you are essentially at the ceiling of current hardware capabilities, there are no meaningful performance upgrades available. However, if you wanted a more cost-effective build that still delivers a great experience, you could theoretically step down to a high-end card with a significantly better value rating.
Your GeForce RTX 4090 is already a top-tier graphics card. While it's technically the limiting factor here (which means you are fully utilizing your GPU's visual horsepower exactly as intended), there is no meaningful upgrade path that would drastically improve your Roblox performance right now. GPU fully utilized at: 1080p low, 1080p medium, 1080p high, 4k low, 4k medium, 4k high. CPU-limited at: 1440p medium, 1440p 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 5 220 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.
