Performance Report
At 1080p, all quality settings exceed 135 FPS. At 1440p, all settings exceed 82 FPS. At 4K, all settings exceed 75 FPS.
The GeForce RTX 5090 is 862% above the recommended GPU (GeForce GTX 660) for Roblox. The Xeon 6781P is 5283% above the recommended CPU (Core 2 Duo).
The Xeon 6781P sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GeForce RTX 5090 still has headroom.
Approximated average price on current market:
Combo price: $11660. At 1080p Ultra, this combo delivers 135 FPS, equivalent to 0.01 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages. Adjacent heavier settings are lightly stabilized to remove prediction jitter that would otherwise create impossible reversals.
At 1080p low, the Xeon 6781P sets the ceiling at about 236 FPS, while the GeForce RTX 5090 could reach 583 FPS. In this scenario, the CPU limits the GPU potential by 60% (FPS gap: 347 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Xeon 6781P is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 5090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 60% | CPU Limits GPU 54% | CPU Limits GPU 49% | CPU Limits GPU 49% |
| 1440p (2K QHD) | CPU Limits GPU 58% | CPU Limits GPU 53% | CPU Limits GPU 47% | CPU Limits GPU 47% |
| 4K (Ultra HD) | CPU Limits GPU 55% | CPU Limits GPU 52% | CPU Limits GPU 47% | CPU Limits GPU 47% |
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 and then monotonic-smoothed across heavier presets and resolutions, not generic utilization heuristics.

Yes, the Xeon 6781P paired with the GeForce RTX 5090 can run Roblox smoothly up to 4k achieving around 75 FPS at Ultra quality. Your GPU is 862% above the recommended specs, and your CPU is 5283% above the recommended requirements.
This CPU + GPU combo costs approximately $11660 ($8960 CPU + $2700 GPU). Your Xeon 6781P 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 9965 is a great upgrade option for around $14813 (Rank #459 for value).
Your Xeon 6781P 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, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 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 6781P and GeForce RTX 5090 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.
