With the heatsinks dismounted, the PCB of the Matrix Platinium looks very intimidating and handsome.
Twelve Hynix 256MB GDDR5 memory modules are used here in a 384bit memory bus configuration. We can't help but feel abit disappointed that ASUS didn't opt to go for a total of 6GB of RAM like Sapphire's flagship HD7970 since most regular gamers of this card will most definitely be using it with a multi-monitor array, where memory usage in games like Battlefield 3 can go over 3GB with all the details turned up.
An extravangant 16+2 phase VRM power design should please the overclockers (ED: moar doesn't mean better), and ASUS even includes a special MOSFET heatsink for those who will using their own heatsink block for water or LN2 cooling.
The DirectCU II cooling solution uses a brute force approach with five copper heatpipes transfering heat from the base to a large fin array which is then dissipated by twin 92mm PWM enabled fans that pushes a lot of air. Under factory settings, the cooler is significantly quieter under load than the reference blower solution, addressing one of the main drawbacks of the HD 7970.
