When the GTX 980 and GTX 970 from Nvidia came along we were very impressed with, among other things, the low TDPs. Now, it seems that thanks to the 145 W TDP of the GTX 970, Gigabyte has been inspired to build a Mini-ITX variant. Yes, you read that right: Gigabyte built a Mini-ITX GTX 970. Its model number is GV-N970IXOC-4GD.
So what did Gigabyte sacrifice to make this happen? The truth is, not a whole lot. Presumably, the VRM circuitry isn't as elaborate, and the cooler certainly isn't either, but the card is still overclocked, running at 1076 MHz Base with a Boost clock of 1216 MHz. Reference GTX 970's run at 1051 MHz and Boost at 1178 MHz. It's not much of an overclock, but it's enough to show that Gigabyte has faith in its design. It is powered by a single 8-pin PCI-Express power connector.
All that power in a tiny package, hats off to Nvidia/Gigabyte-I presume it will fit into Gigabytes very own tiny PC console style box thingamabob perfectly and even smaller Steam boxes.
