As is normally the case with more recent GeForce cards at the launch of the GTX 780 we saw a whole range of manufacturers release reference design, stock clocked cards. Over the past couple of months though those same manufacturers have been busy creating custom cooled, overclocked models and barely a week goes by without a new, "fastest ever" 780 hitting the market.
Today ZOTAC launch their take on a custom cooled 780 with a significant overclock applied at the factory… over 1000MHz base. We will compare it to an existing "super overclock" edition as well as taking a 7970 GHz Edition, water-cooling it and overclocking well past retail overclocked models to see how it compares in game such as Crysis 3 and Metro: Last Light.
ZOTAC GeForce GTX 780 AMP! Edition (Overclocked)
ZOTAC stick with a familiar box design, noting the AMP! /Overclock features and giving prominence to their game bundle. That is the Splinter Cell Compilation which includes a code for Blacklist. Also bundled inside we find a CD, manual, power cable, and DVI to VGA dongle.
Not long ago ZOTAC significantly changed their cooler on AMP! Edition cards and a version of that appears here too. Using a metal shroud rather than plastic and moving to a 3fan design with orange blades this is a model which stands out. Under those fans is a large aluminium heatsink, copper GPU block and 5 heatpipes. ZOTAC use a Black PCB on this card and we can see from the back that it featuers the standard 2 SLI connectors which will allow us to add in multiple 780s for enhanced performance if we wish.
Around at the card outputs there are no surprised as we have four present on this GTX 780 with two Dual-Link DVIs starting us off, followed by a HDMI 1.4 and then a full size DisplayPort connector. The GTX 780 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.
The reference specifications for the 28nm GeForce GTX 780 are 863MHz core (base clock) with a boost clock of 900MHz and the 3GB of GDDR5 memory is set to 1502MHz. ZOTAC significantly increase this 1006MHz Core, 1059MHz boost and 1552MHz on the memory. There are 192 Texture units within the core along with 48 ROPS, 5 graphics processing clusters and 12 streaming multiprocessors. For the CUDA Cores ZOTAC and NVIDIA have gone for a 2304 "core" design and our memory bus is 384-bit. 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, adaptive V-Sync and 3D Vision.
