Galaxy has just listed another variant of GTX 680 card on their pages. GTX 680 SOC is based on non-reference design featuring Super Overclocked Version signature.
This model is factory-overclocked, featuring core clock of 1202 MHz (1267 MHz for Boost Clock) and reference memory clock of 1502 MHz. It has standard 2048 MB of GDDR5 memory. GTX 680 SOC 2GB requires two 8-pin power connectors for even more overclocking.
Galaxy GTX 680 SOC 2GB has a non-reference display outputs. It’s equipped with triple mini-HDMI and one DisplayPort connectors. It’s built on the same white PCB known from KFA2 HOF model.
So this card looks similar to KFA2 GTX 680 Hall Of Fame 2GB Edition (the one with white PCB). It is uncertain whether Galaxy is going to release their HOF model as well. Most likely this is only a clone of this HOF model and both companies will offer their products instead.
