Performance Report
At 1080p, all quality settings exceed 282 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 295 FPS. At 4K, all settings exceed 286 FPS.
The GeForce RTX 4090 is 843% above the recommended GPU (GeForce GTX 660) for Roblox. The Core i5-13450HX is 1035% above the recommended CPU (Core 2 Duo).
At lower resolutions (1080p medium), the Core i5-13450HX determines the performance ceiling. As graphical load increases at (1080p low, 1440p (low/ultra), all 4k settings), the GeForce RTX 4090 takes over as the primary performance factor. The system is well balanced at 1080p (high/ultra), 1440p (medium/high).
At 4k low, the GeForce RTX 4090 sets the ceiling at about 264 FPS, while the Core i5-13450HX has headroom up to 351 FPS. In this scenario, the GPU limits the CPU potential by 25% (FPS gap: 87 FPS). Overall distribution: GPU limits 7/12 cells, CPU limits 1/12, balanced 4/12.
Your GeForce RTX 4090 is the limiting side in the heaviest mismatch. This means part of the Core i5-13450HX frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 11% | CPU Limits GPU 7% | Balanced | Balanced |
| 1440p (2K QHD) | GPU Limits CPU 19% | Balanced | Balanced | GPU Limits CPU 7% |
| 4K (Ultra HD) | GPU Limits CPU 25% | GPU Limits CPU 15% | GPU Limits CPU 13% | GPU Limits CPU 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 Core i5-13450HX + GeForce RTX 4090 pairing runs this title with CPU utilization between 13% and 45% and GPU utilization between 13% and 55%. Core i5-13450HX keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 26% at 1080p to 38% at 4K, while CPU averages move from 28% to 29%.
Neither component is close to saturation: CPU tops out at 45% and GPU at 55%. This pattern suggests possible engine-side limits, an FPS cap, or workload constraints unrelated to raw hardware throughput.
At 1080p, averages sit around CPU 28% and GPU 26%. At 1440p, that shifts to CPU 29% and GPU 35%, and at 4K it reaches CPU 29% and GPU 38%. 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 30% (14-45%) and GPU 40% (24-55%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core i5-13450HX remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Core i5-13450HX and GeForce RTX 4090 remain reasonably matched for this title.

Yes, the Core i5-13450HX paired with the GeForce RTX 4090 can run Roblox smoothly up to 4k achieving around 292 FPS at Ultra quality. Your GPU is 843% above the recommended specs, and your CPU is 1035% 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. 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, 1440p low, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra. CPU-limited at: 1080p medium.
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 Core i5-13450HX 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.
