Performance Report
At 1080p, all quality settings exceed 220 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 201 FPS. At 4K, all settings exceed 198 FPS.
The GeForce RTX 4090 is 843% above the recommended GPU (GeForce GTX 660) for Roblox. The EPYC 7351P is 1035% above the recommended CPU (Core 2 Duo).
The EPYC 7351P determines the performance ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GPU has headroom.
At 1440p ultra, the EPYC 7351P sets the ceiling at about 196 FPS, while the GeForce RTX 4090 could reach 264 FPS. In this scenario, the CPU limits the GPU potential by 26% (FPS gap: 68 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your EPYC 7351P 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 17% | CPU Limits GPU 16% | CPU Limits GPU 14% | CPU Limits GPU 17% |
| 1440p (2K QHD) | CPU Limits GPU 22% | CPU Limits GPU 24% | CPU Limits GPU 23% | CPU Limits GPU 26% |
| 4K (Ultra HD) | CPU Limits GPU 13% | CPU Limits GPU 12% | CPU Limits GPU 17% | CPU Limits GPU 19% |
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 EPYC 7351P + GeForce RTX 4090 pairing runs this title with CPU utilization between 18% and 41% and GPU utilization between 9% and 47%. EPYC 7351P keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 22% at 1080p to 31% at 4K, while CPU averages move from 28% to 29%.
Neither component is close to saturation: CPU tops out at 41% and GPU at 47%. This pattern suggests possible engine-side limits, an FPS cap, or workload constraints unrelated to raw hardware throughput.
At 1080p, averages sit around CPU 28% and GPU 22%. At 1440p, that shifts to CPU 29% and GPU 30%, and at 4K it reaches CPU 29% and GPU 31%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
4K (Ultra HD) High is the most balanced preset based on this dataset. It runs around CPU 30% (19-41%) and GPU 33% (19-47%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while EPYC 7351P remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the EPYC 7351P and GeForce RTX 4090 remain reasonably matched for this title.

Yes, the EPYC 7351P paired with the GeForce RTX 4090 can run Roblox smoothly up to 4k achieving around 198 FPS at Ultra quality. Your GPU is 843% above the recommended specs, and your CPU is 1035% above the recommended requirements.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
For Roblox, upgrading the CPU would have the biggest impact on performance. The EPYC 7351P 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 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 EPYC 7351P 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.
