The Card
For the GeForce 40 Series, Gigabyte has designed a new visual theme for their cards. The main cooler is now black, with a gray metal backplate.
In terms of size, the Gaming OC is slightly bigger than the NVIDIA RTX 4090 Founders Edition.
Dimensions of the card are 34.5 x 15.5 cm, and it weighs 2020 g.
Installation requires four slots in your system.
Display connectivity includes three standard DisplayPort 1.4a ports and one HDMI 2.1a (same as Ampere).
NVIDIA introduced the concept of dual NVDEC and NVENC Codecs with the Ada architecture. This means there are 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 4x PCIe 8-pin is included, you can also run the card with just three 8-pins.
This BIOS switch lets you select between the default OC BIOS and a silent BIOS, which runs the fans on a slightly more relaxed fan curve.
Teardown
Gigabyte's thermal solution uses a vapor-chamber and eight heatpipes. The main cooler also provides cooling for the VRM circuitry and memory chips—there's a lot of thermal pads here.
The backplate is made of metal and protects the card against damage during installation and handling.
