Nvidia has yet another success in the form of its latest 700 series GPUs. Kepler (the 600 series) was a big hit in any case and the new 700 series refines it further, adding lower power requirements, new features and, of course, more performance. We already saw what the GTX 780 is capable of and now it’s time to take a look at the GTX 770, a card that will eventually replace the GTX 670. ZOTAC promptly sent us its AMP Edition for review so we can see how much of a performance difference you get as compared to the stock card.
Design and build
ZOTAC has done away with the stock cooler and has gone with its own "Dual Silencer" cooler. The custom cooler has an open air design and features a large aluminium heatsink that’s cooled by two fans, instead of one. While the orange fans are definitely more eye catching, they also introduce fan noise. The stock cooler, on the other hand, uses vapour chamber technology and a blower-style fan, which is a lot quieter and dispenses hot air directly outside the chassis.
Good design and build
Connectivity wise we have two DVI ports and full-sized HDMI and DisplayPort. There are exhaust vents at the back, but it’s frankly not of much use because of the open air design. The ports for power are also re-arranged a little. You also have SLI support. The card is very long at around 10.5 inches, so make sure you have plenty of room in your chassis.
The GTX 770 is pretty much identical to the GTX 780, right down to the last ROP. Based on the same GK104 silicon, the GTX 770 packs in 1536 CUDA cores or shaders, 32 ROPs and a 256-bit memory bus, just like the GTX 680. What’s changed is the much faster 1753MHz memory (7012MHz effective), which is the fastest GDDR5 memory to date. This being the AMP Edition, ZOTAC has bumped up the clocks a little more out-of-the-box. The core now runs at 1150MHz (1045MHz on stock) and the memory is clocked at 7200MHz, so it’s a very good bump all round. Other features are similar to what you get in the GTX 780, such as GPU Boost 2.0, advanced AA modes (TXAA and FXAA) as well as full support for SHIELD and Shadow Play.
The dual-slot cooler
As a bonus, ZOTAC also bundles a Splinter Cell compilation pack that includes full version of Double Agent, Conviction and a download key for the yet to be released game, Blacklist.
