EVGA released a reference-based GeForce GTX Titan X today and promised two non-reference models. First up is the EVGA GeForce GTX TITAN X Superclocked, this card is basically the reference model with higher clockspeeds. The memory clockspeed remains at 7010MHz but the base/boost frequencies are yet to be determined.
Next is the EVGA GeForce GTX TITAN X Hydro Copper, this is a watercooled model that uses the new block from EK Waterblocks. Just like the Superclocked version, this model has 7010MHz memory but the other clockspeeds are still a mystery and we don't know when these parts will hit retail shelves.
