Japanese site 4Gamer.net has reviewed Zotac’s upcoming GT 630 Zone Edition and GT 640 GDDR5 GPUs and revealed that they will not be powered by Nvidia’s GK108 or GK107 “Fermi” core, but instead will utilize the GK208 “Kepler” core.
The GT 630 Zone Edition has a length of 148 mm and like other Zone Edition GPUs, features a fanless, passive cooler that is just 10 mm shy of meeting the low profile specification. Though the GT 640 GDDR5 also measures 148 mm in length, it includes a 2 slot design with a single 50 mm cooling fan. With regards to outputs, both graphics cards feature a single Dual-Link DVI-D port, one HDMI connector and analog RGB via a 15-pin D-Sub port.
