12GB GDDR6X Ampere GPU

The NVIDIA GeForce RTX 3080 Ti Founders Edition is a 12GB graphics card built on the Ampere architecture. It connects via PCI Express 4.0 and features 10240 CUDA cores with a 384-bit memory interface. Core clock runs at 1365 MHz and boost clock reaches 1665 MHz. The card supports DirectX 12 Ultimate and OpenGL 4.6 for modern rendering workloads.

4K gaming and creative workloads

This card suits users targeting 7680 x 4320 resolution on a single GPU with HDMI 2.1 and three DisplayPort 1.4a outputs. Virtual reality ready certification covers headset use. Buyers focused on lower resolutions or strict power budgets should evaluate less demanding models. The 350W thermal design power demands serious cooling headroom in the chassis.

750W PSU and PCIe 4.0 slot

Verify your power supply delivers at least 750W with the required PCIe connectors for 350W board power. Confirm the motherboard provides a full-length PCI Express 4.0 x16 slot and that case clearance fits a dual-slot Founders Edition cooler. Ensure the display chain uses HDMI 2.1 or DisplayPort 1.4a cables to reach 7680 x 4320 at high refresh rates.

Questions about this item

What power supply wattage is recommended for the 350W TDP of this RTX 3080 Ti?

A 750W power supply is recommended to support the 350W thermal design power of this graphics card.

Will this PCI Express 4.0 card work in my older motherboard with a PCI Express 3.0 slot?

Yes, the card is compatible with PCI Express 3.0 slots, though it will operate at 3.0 speeds rather than the full 4.0 bandwidth.

How can I confirm the 12GB GDDR6X memory is running at the 384-bit interface width after installation?

GPU monitoring software will report the memory bus width as 384-bit and show 12GB of GDDR6X memory detected.
