Technical data / specifications

Asus provided the Matrix GTX 285 with an eight plus two phase power design which shows a positive effect regarding stability. Still the same is the memory interface: 512 bit wide with 1024 MByte GDDR3 memory, that is standard. Only the memory clockrates haven been increased a little to 1242 MHz. Looking at the GPU you'll also find slightly increased clock rates. The GPU now clocks with 662 MHz rather than the standard 648 MHz. Even the thermal design power is roughly at the same level as a reference card.
