At 1080p low, the Core i7-9700K sets the ceiling at about 360 FPS, while the GeForce RTX 4090 could reach 443 FPS. In this scenario, the CPU limits the GPU potential by 19% (FPS gap: 83 FPS). Overall distribution: CPU limits 3/12 cells, GPU limits 3/12, balanced 6/12.
Your Core i7-9700K 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 19% | CPU Limits GPU 12% | CPU Limits GPU 8% | Balanced |
| 1440p (2K QHD) | Balanced | Balanced | Balanced | Balanced |
| 4K (Ultra HD) | GPU Limits CPU 19% | GPU Limits CPU 9% | Balanced | GPU Limits CPU 7% |
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 i7-9700K + GeForce RTX 4090 pairing runs this title with CPU utilization between 32% and 65% and GPU utilization between 12% and 54%. Core i7-9700K keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 25% at 1080p to 37% at 4K, while CPU averages move from 48% to 49%.
The utilization pattern is relatively balanced. The GeForce RTX 4090 reaches 38% average at its highest-load preset, while the Core i7-9700K peaks at 50% average, with no single component consistently acting as a hard bottleneck.
At 1080p, averages sit around CPU 48% and GPU 25%. At 1440p, that shifts to CPU 49% and GPU 33%, and at 4K it reaches CPU 49% and GPU 37%. 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 50% (35-65%) and GPU 38% (23-54%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core i7-9700K remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Core i7-9700K and GeForce RTX 4090 remain reasonably matched for this title.

Yes, the Core i7-9700K paired with the GeForce RTX 4090 can run Roblox smoothly up to 4k achieving around 232 FPS at Ultra quality. Your GPU is 843% above the recommended specs, and your CPU is 557% above the recommended requirements.
This CPU + GPU combo costs approximately $1849 ($200 CPU (Rank #274 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: 4k low, 4k medium, 4k ultra. CPU-limited at: 1080p low, 1080p medium, 1080p high.
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 i7-9700K 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.
