Hardware Canucks tried the NVIDIA's GTX TITAN Z; GK110 Squared
A quote from the article:
We first talked about NVIDIA's TITAN Z back when it was unveiled during the GPU Technology Conference in March. Since then, additional details have been non-existent but it goes without saying that during the last two months tweaking and no small amount of core binning was needed to bring the Z to market. The original launch date was actually April 29th so we?re looking at a month's worth of delays for fine tuning. Now it is about to hit the channels in understandably limited quantities.NVIDIA's GTX TITAN Z; GK110 Squared @ Hardware Canucks
Now that launch day is finally here, we finally know a bit more about the TITAN Z and its potential capabilities. First and foremost the price has remained stable at a whopping $3000 which, for those keeping track at home, is enough coin to buy you two AMD R9 295X2 cards or three TITAN Blacks. However, this isn't a simple gaming card; it has much broader reaching implications.
Another mystery was clock speeds. With an air-based cooler and an insane amount of heat being generated by two fully unlocked GK110 cores and 12GB (yes you read that right) of GDDR5, some expected frequencies to suffer. Those predictions came true since things have been dialed down?way down.
