ZOTAC use familiar styling for their box and focus very much on the AMP! Edition branding while listing some key features. Inside the box we find a decent bundle which includes driver CD, manual, power cables and DVI to VGA dongle. Also included are details on trial software.

ZOTAC use a metal shroud on their GTX 670 and a PCB which is very similar in design to the GTX 680, rather than the reference GTX 670. Two orange fans are present and these sit above aluminium fins and running through those are four heatpipes which connect to the copper GPU block. Various heatisnks are placed on components across the PCB to enhance cooling and turning round to the back of the card we can see that two SLI connectors are present which lets us know we can connect multiple cards together for enhanced performance.

For power requirements we have two 6-pin connectors present. These point out the top of the card rather than the back providing the card with 170-200w when combined with the PCIe connector.

Around at the card outputs we have four present with two Dual-Link DVIs starting us off, followed by a HDMI 1.4a and then a full size DisplayPort 1.2 connector. The GTX 670 is capable of running four screens at one time with three available for surround gaming at resolutions such as 5760×1080 and the fourth running off a separate controller for desktop applications such as messaging. It is also worth noting that NVIDIA now offer bezel correction hotkeys for quick in-game changes to show any hidden content and that when setting up three screens we simply click the enable option, follow the simple wizard which allows us to drag and drop the right order making the process easy. As an extra touch the taskbar is now present on the centre display and we can maximise windows to individual screens not just the entire bank of displays.

The reference specifications for the GeForce GTX 670 are 915MHz core (base clock) with a boost clock of 980MHz and the 2GB of GDDR5 memory is set to 1500MHz. ZOTAC opt for 1098MHz base, 1176MHz Boost and 1652MHz memory. There are 112 Texture units within the core along with 32 ROPS, 4 graphics processing clusters and 7 streaming multiprocessors. For the CUDA Cores NVIDIA have gone for a 1344 "core" design and our memory bus is 256-bit (4×64). PCIe 3.0, DirectX 11.1 and DirectCompute are all supported on this card as is acceleration of high definition content and the card can output 7.1 audio over HDMI as well as support PhysX, 4K displays and 3D Vision.
