Performance Report
At 1080p, all quality settings exceed 259 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 230 FPS. At 4K, all settings exceed 175 FPS.
The GeForce RTX 4090 is 843% above the recommended GPU (GeForce GTX 660) for Roblox. The Xeon E7-8891 v3 is 887% above the recommended CPU (Core 2 Duo).
The Xeon E7-8891 v3 determines the performance ceiling at all 1080p settings, 1440p (medium/high/ultra), 4k (medium/high/ultra), while the GPU has headroom. The system is well balanced at 1440p low, 4k low.
Approximated average price on current market:
Combo price: $2067. At 1080p Ultra, this combo delivers 259 FPS, equivalent to 0.13 FPS per dollar.

At 4k ultra, the Xeon E7-8891 v3 sets the ceiling at about 180 FPS, while the GeForce RTX 4090 could reach 228 FPS. In this scenario, the CPU limits the GPU potential by 21% (FPS gap: 48 FPS). Overall distribution: CPU limits 10/12 cells, GPU limits 0/12, balanced 2/12.
Your Xeon E7-8891 v3 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 6% | CPU Limits GPU 15% | CPU Limits GPU 9% | CPU Limits GPU 7% |
| 1440p (2K QHD) | Balanced | CPU Limits GPU 9% | CPU Limits GPU 9% | CPU Limits GPU 9% |
| 4K (Ultra HD) | Balanced | CPU Limits GPU 14% | CPU Limits GPU 19% | CPU Limits GPU 21% |
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.

Yes, the Xeon E7-8891 v3 paired with the GeForce RTX 4090 can run Roblox smoothly up to 4k achieving around 175 FPS at Ultra quality. Your GPU is 843% above the recommended specs, and your CPU is 887% above the recommended requirements.
This CPU + GPU combo costs approximately $2067 ($418 CPU (Rank #540 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 E7-8891 v3 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 low, 1080p medium, 1080p high, 1080p ultra, 1440p medium, 1440p high, 1440p ultra, 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 E7-8891 v3 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.
