Galaxy GeForce GTX 680 4GB gets pixellized

Posted on Monday, March 26 2012 @ 23:17:12 CEST by

TechPowerUp got its hands on photos of the Galaxy GeForce GTX 680 4GB edition, a new non-reference variant with custom cooling and a base clockspeed of 1100MHz.
It did this, by using sixteen 2 Gbit GDDR5 memory chips. There's more to this card than its memory amount. The PCB is designed from scratch, and uses a strong 5+2 phase VRM, which draws power from 6+8 pin power connectors. The VRM appears to make use of International Rectifier-made DirectFETs. Perhaps Galaxy also went off-spec with the VRM controller, and maybe it supports a software interface. The cooler is an in-house design by Galaxy, too. It consists of a large heat-pipe fed aluminum fin array, ventilated by two 90 mm fans.
