ASUS ROG Strix RTX 3070 Ti 8GB Overview

The ASUS ROG Strix RTX 3070 Ti O8G Gaming is a graphics card built around the NVIDIA GeForce RTX 30 Series GPU with 6144 CUDA cores. It connects via PCI Express 4.0 and carries 8GB of GDDR6X memory on a 256-bit bus running at 19000 MHz. Boost clocks reach 1875 MHz in OC mode and 1845 MHz in Gaming mode.

Who Should Choose This Card

This model suits builders who want a factory-overclocked RTX 3070 Ti with a 2.9-slot cooler and four-display support over 2×HDMI 2.1 and 3×DisplayPort 1.4a. Users needing more than 8GB VRAM or a single-slot form factor should consider other options. SLI is not supported.

8GB GDDR6X Capacity and Headroom

The 8GB frame buffer handles 1440p gaming and 4K workloads at 7680 x 4320 maximum resolution comfortably. Memory bandwidth from the 256-bit GDDR6X interface provides headroom for high texture settings. Demanding 4K titles with heavy ray tracing may exhaust the 8GB capacity before the GPU reaches its compute limit.

Highlights

  • 8GB GDDR6X memory at 19000 MHz for high-bandwidth performance
  • Boost clock up to 1875 MHz in OC mode for faster frame rates
  • 6144 CUDA cores accelerate rendering and compute workloads
  • PCI Express 4.0 interface doubles bandwidth over PCIe 3.0
  • Three DisplayPort 1.4a and two HDMI 2.1 outputs drive up to four 8K displays

Questions about this item

What power connectors does the ROG Strix RTX 3070 Ti O8G need from my PSU?

The card draws power through three 8-pin PCIe connectors; your power supply must provide all three and enough spare wattage for the rest of the system.

Will the 2.9-slot thickness block the PCIe x1 slot under my top GPU slot?

At 2.9 slots wide the cooler covers the adjacent expansion slot, so a motherboard with the first x16 slot at the very top edge leaves no room for an x1 card beneath it.

How can I confirm the 1875 MHz OC boost clock is active after driver installation?

Open GPU-Z or the ASUS GPU Tweak III overlay while a 3D load runs; the sensor tab should report a GPU clock at or above 1875 MHz when OC mode is selected.
