Frequently Asked Questions

What CPU pairs best with RTX 4090?
The RTX 4090 pairs best with high-end CPUs like the Intel Core i9-14900K or AMD Ryzen 9 7950X. These processors provide optimal performance without bottlenecking the GPU. Mid-range CPUs like the i7-14700K or Ryzen 7 7800X3D also work well with minimal bottlenecking.
Will RTX 4090 bottleneck with Intel Core i7-14700K?
There will be minimal bottlenecking with the i7-14700K, typically around 2-5% depending on the game and resolution. This is still very playable and you'll get excellent performance. For optimal performance, consider upgrading to an i9 series.
What PSU do I need for RTX 4090?
We recommend at least a 850W 80+ Gold power supply for the RTX 4090. The GPU has a 450W TDP, and you need additional power for your CPU, motherboard, and other components. A high-quality PSU ensures stable power delivery and prevents system instability.
Is RTX 4090 good for 4K gaming?
Absolutely! The RTX 4090 is excellent for 4K gaming with ray tracing enabled. It can achieve 60+ FPS in most games at 4K with ultra settings and ray tracing. With DLSS 3.0, you can even push higher frame rates while maintaining excellent image quality.
How does RTX 4090 compare to RTX 3090?
The RTX 4090 offers approximately 60-80% better performance than the RTX 3090, with improved ray tracing capabilities, more efficient power consumption, and better AI performance. It's built on the new Ada Lovelace architecture with enhanced efficiency and features.
When was RTX 4090 released?
The RTX 4090 was released on October 12, 2022, with a starting MSRP of $1599. It's now available from various retailers and is considered the previous generation flagship GPU.
Do I need a new motherboard for RTX 4090?
You need a motherboard with a PCIe 4.0 x16 slot for optimal performance, though PCIe 3.0 x16 will work with minimal performance loss. Most modern motherboards (Z790, X670E, B650E) support PCIe 4.0. Check your motherboard specifications to confirm compatibility.
