This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k ultra, the Xeon Gold 6148 sets the ceiling at about 190 FPS, while the GeForce RTX 4090 could reach 226 FPS. In this scenario, the CPU limits the GPU potential by 16% (FPS gap: 36 FPS). Overall distribution: CPU limits 4/12 cells, GPU limits 0/12, balanced 8/12.
The Xeon Gold 6148 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) | Balanced | CPU Limits GPU 14% | Balanced | Balanced |
| 1440p (2K QHD) | Balanced | Balanced | Balanced | Balanced |
| 4K (Ultra HD) | Balanced | CPU Limits GPU 13% | CPU Limits GPU 15% | 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 6148 + GeForce RTX 4090 pairing runs this title with CPU utilization between 16% and 42% and GPU utilization between 13% and 54%. Xeon Gold 6148 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 37% at 4K, while CPU averages move from 28% to 28%.
Neither component is close to saturation: CPU tops out at 42% and GPU at 54%. 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 28% and GPU 26%. At 1440p, that shifts to CPU 28% and GPU 35%, and at 4K it reaches CPU 28% 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 29% (16-42%) and GPU 38% (23-54%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Xeon Gold 6148 remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Xeon Gold 6148 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 6148 paired with the GeForce RTX 4090 can run Roblox smoothly up to 4k achieving around 185 FPS at Ultra quality. Your GPU is 843% above the recommended specs, and your CPU is 1225% above the recommended requirements.
This CPU + GPU combo costs approximately $1939 ($290 CPU (Rank #497 Value) + $1649 GPU (Rank #77 Value)). Since the CPU is the main limiting factor, investing in a stronger processor will improve your framerates and overall value. For example, the Xeon Platinum 8454H is a great upgrade option for around $6540 (Rank #1 for value).
For Roblox, upgrading the CPU would have the biggest impact on performance. The Xeon Gold 6148 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 medium, 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 6148 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.
