This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p medium, the Xeon Gold 6338N sets the ceiling at about 320 FPS, while the GeForce RTX 4090 could reach 394 FPS. In this scenario, the CPU limits the GPU potential by 19% (FPS gap: 74 FPS). Overall distribution: CPU limits 10/12 cells, GPU limits 0/12, balanced 2/12.
Your Xeon Gold 6338N 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 11% | CPU Limits GPU 19% | CPU Limits GPU 6% | Balanced |
| 1440p (2K QHD) | CPU Limits GPU 10% | CPU Limits GPU 16% | CPU Limits GPU 8% | Balanced |
| 4K (Ultra HD) | CPU Limits GPU 8% | CPU Limits GPU 18% | CPU Limits GPU 17% | CPU Limits GPU 16% |
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.
A component can still be the FPS limiter without reaching 100% utilization. The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

The Xeon Gold 6338N + GeForce RTX 4090 pairing runs this title with CPU utilization between 11% and 24% and GPU utilization between 1% and 39%. Xeon Gold 6338N keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 11% at 1080p to 24% at 4K, while CPU averages move from 18% to 20%.
Neither component is close to saturation: CPU tops out at 24% and GPU at 39%. This pattern suggests possible engine-side limits, an FPS cap, or workload constraints unrelated to raw hardware throughput. It also shows why low utilization does not automatically mean there is no FPS limiter.
At 1080p, averages sit around CPU 18% and GPU 11%. At 1440p, that shifts to CPU 18% and GPU 11%, and at 4K it reaches CPU 20% and GPU 24%. 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 20% (16-24%) and GPU 26% (13-39%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Xeon Gold 6338N remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Xeon Gold 6338N and GeForce RTX 4090 remain reasonably matched for this title.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.

Yes, the Xeon Gold 6338N paired with the GeForce RTX 4090 can run Roblox smoothly up to 4k achieving around 186 FPS at Ultra quality. Your GPU is 843% above the recommended specs, and your CPU is 1821% above the recommended requirements.
This CPU + GPU combo costs approximately $4849 ($3200 CPU (Rank #445 Value) + $1649 GPU (Rank #77 Value)). Your Xeon Gold 6338N 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 processor with a significantly better value rating. For example, the EPYC 4585PX is a great upgrade option for around $699 (Rank #66 for value) while costing less than your current CPU.
Your Xeon Gold 6338N is already an incredibly powerful processor. While it's technically the first component to hit its limit (which is completely normal in state-of-the-art builds), there is no meaningful upgrade path that would drastically improve your Roblox performance right now. CPU fully utilized at: 1080p low, 1080p medium, 1080p high, 1440p low, 1440p medium, 1440p high, 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 Xeon Gold 6338N 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.
