Frequently Asked Questions
What CPU do I need for Portal with RTX?
A Intel Core i5-7500 Processor-class processor meets the recommended bar. For high frame rates a Intel Core i7-1195G7 Processor gives more headroom. Verify any chip with our free Can I Run It checker.
Does the CPU matter for Portal with RTX, or just the GPU?
Gaming is GPU-bound, so the graphics card matters most for raw settings and resolution. But the CPU sets your frame-rate ceiling — it matters most at high refresh rates, at 1080p, and in CPU-heavy games (strategy, simulation, open-world). A weak CPU paired with a strong GPU causes a bottleneck.
Will my CPU bottleneck Portal with RTX?
It can, if your CPU is much weaker than your GPU. Check the exact balance of your build with our free bottleneck calculator before buying either component.
