ZOTAC seems to have a 2-pronged approach to the GeForce GTX 670, depending on the region it's being sold in. While it took advantage of the compact reference PCB by NVIDIA to come up with the space-saving GTX 670 TwinCooler (ZTGTX670-2GD5TCR001), it did the exact with the GTX 670 Extreme Edition. The card is based on the same exact design as the GTX 680 Extreme Edition, down to its lavish voltage regulation circuitry, with just the GTX 670 ASIC taking the place of the GTX 680.

The card ships with out of the box clock speeds of 1111 MHz (GPU base), 1202 MHz (GPU Boost), and 1652 MHz (memory actual), or 6.60 GHz (memory effective). It draws power from 6-pin and 8-pin PCIe power connectors, and conditions power using a 13-phase VRM that consists of noise-free chokes and PowIRstage DrMOS chips by International Rectifier. Power is further conditioned by a trio of multi-phase FPCAPs, and tantalum capacitors. Like the GTX 680 Extreme Edition, the card features the entire overclocker-friendly feature-set, including OC+ Module, dual-BIOS with LN2-friendly BIOS, voltage measurement points, temperature and phase loading LEDs.Cooling the beast is the same swanky cooling solution as the one found on the GTX 680 Extreme Edition. Staying within the confines of 2 expansion slots, the cooler packs a large aluminum fin heatsink that spans the entire length of the card, which uses five 8 mm-thick nickel-plated copper heat pipes that draw heat from the copper GPU base, to the aluminum fin stack. The heatsink is then ventilated by a pair of 92 mm fans.

According to numbers by Expreview, the ZOTAC GTX 670 Extreme Edition outperforms stock GeForce GTX 680. The reviewer was able to overclock the GPU offset to 1403 MHz (1300/1403) with a core voltage of 1.25V, and memory speed of 1850 MHz (7.40 GHz effective), with the stock air cooling, and score P9247 points in 3DMark 11 (performance preset).ZOTAC GTX 670 Extreme Edition is exclusive for select markets in Asia. The rest of the world should make do with the GTX 670 AMP! Edition.
