Zotac GeForce GT 640 Zone Edition - Micromart | Aug 2013

ZOTAC’s version of the GeForce GT 640 comes in two versions – a regular, active-cooled version, and a silent ‘Zone Edition.’ The GK 107 GPU uses a 28nm Kepler process, and clocks at 902MHz, which is a little slower than the reference design of 950MHz – presumably to keep the temperature down. That said, this is one of the few cards with 2GB of RAM, even if it is slightly slower GDDR3, not GDDR. In terms of I/O ports, you get two DVIs and a mini-HDMI, but no DisplayPort.
