The Card

The front of the Gigabyte RTX 4070 Ti Gaming OC is mostly black, with silvery highlights on the fan hub. On the back you'll find a high-quality metal backplate.


Gigabyte has installed RGB illumination on the fans, but the lighting is tied into the fan's PWM signal. So, if the fans are stopped there is no lighting. Near the top right there's a second RGB element.


Dimensions of the card are 33.5 x 14.0 cm, and it weighs 1537 g.


Installation requires three slots in your system.


Display connectivity includes three standard DisplayPort 1.4a ports and one HDMI 2.1a (same as Ampere).

NVIDIA introduces the concept of dual NVDEC and NVENC Codecs with the Ada architecture. This means there are now two independent sets of hardware-accelerators; so you can encode and decode two streams of video in parallel, or one stream at double the FPS rate. The new 8th Gen NVENC now accelerates AV1 encoding, besides HEVC. You also get an "optical flow accelerator" unit that is able to calculate intermediate frames for videos, to smooth playback. The same hardware unit is used for frame generation in DLSS 3.


The card uses the new 12+4 pin ATX 12VHPWR connector, which is rated for up to 600 W of power draw. An adapter cable from 2x PCIe 8-pin is included. Of course the 4x 8-pin to 16-pin adapter cables from RTX 4090 will also work with the RTX 4070 Ti.


Near the power connector, Gigabyte has placed their dual BIOS switch, which lets you switch from the default "OC" BIOS, to a "Silent" BIOS, with a much more relaxed fan curve.

Teardown

The main heatsink provides cooling for the GPU chip, memory chips and VRM circuitry. Unlike many other cards which use a classic heatsink baseplate, Gigabyte has installed a vapor-chamber baseplate, which soaks up the heat and moves it to the heatpipes quickly. Seven heatpipes then transfer heat to the cooling fins.


The backplate is made from metal, it protects the card against damage during installation and handling.
