Zotac GeForce GTX 660 Ti AMP! Edition
Zotac went all-out with its GeForce GTX 660 Ti AMP! Edition (ZT-60804-10P). It shares the highest base GPU clock rate with Gigabyte’s card, and also leverages factory-overclocked memory to help compensate for the cut-back memory bus. The card is based on a short PCB and a very compact cooler, making the Zotac GeForce GTX 660 Ti AMP! Edition the smallest and fastest board in our round-up.
Interestingly, Zotac doesn't employ direct memory cooling in spite of the high data rates. Temperatures that nearly reach 70 degrees Celsius on the back of the card make this a questionable choice, especially if it's going into a compact chassis.
