The Card

The ASUS RTX 4070 TUF is instantly recognizable, thanks to its bulky look that's a feature of the TUF series. On the other side you'll find a metal backplate that has a cutout for air to flow through.


Dimensions of the card are 30 x 14 cm, and it weighs 1180 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).

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 a single 8-pin power connector, which, together with the PCIe slot, is specified for up to 225 W power draw. Some other RTX 4070 cards like the NVIDIA Founders Edition come with the new 16-pin connector, but they are limited to the same power draw levels. NVIDIA has given their partners free choice on what connector they use, and I suspect the classic 8-pin is a little bit cheaper to implement.


ASUS has implemented a dual BIOS feature on their RTX 4070 cards. The default setting is "Quiet," which is a change from the previous default. You may optionally enable a "Performance" mode that increases the fan speeds to lower temperatures.

Teardown

Removing the top shroud is easy, which includes the fans, so they can be replaced easily in a few years.


ASUS's heatsink uses six heatpipes to keep the card cool. The main cooler also provides cooling for the memory chips and VRM circuitry.


The metal backplate protects the card against damage during installation and handling.
