ZOTAC GeForce GTX 770 AMP! Edition 2GB
The GeForce GTX 770 AMP! Edition from Zotac is packed into a smaller box than the Palit, yet the box is still surprisingly large for a graphics card. There is no flip cover here, but you can read quite a lot of information about the product from the front and back of the packaging.
The accessories include two power adapters, a CD with software, a user manual, a Zotac sticker, and a Splinter Cell Compilation coupon.
Manufactured in China, the GeForce GTX 770 AMP! Edition is shipped with a 5-year warranty for $449, which is 12.3% higher than the recommended price of the GeForce GTX 770.
The Zotac is smaller than the Palit: 10 mm shorter and 10 mm narrower. So it seems to be a better choice for multi-GPU configurations. The entire face side of the PCB is covered with a figured metal casing with two bright orange fans.
The Zotac has the same video connectors as the Palit or the reference GeForce GTX 770 but the vent holes in its mounting bracket are large so that the hot air could be better exhausted from the computer case.
The Zotac is not original in its MIO and power connectors, either:
A 600-watt PSU is recommended for a computer with one such card.
The PCB resembles the Zotac GeForce GTX 680 AMP! Edition but with the complete set of power transistors.
The power system follows the 5+2 formula with five phases for the GPU and 2 phases for the graphics memory and PLL.
It is managed by a five-phase RT8802A PWM controller from Richtek Technology which is located on the reverse side of the PCB.
The Palit seems to have a more advanced power system than the Zotac.
The GPU is the same revision as Palit’s but was manufactured 4 weeks earlier (9th week of 2013).
The clock rates (1150/1202 MHz) and the rest of the specs are the same as those of the above-discussed Palit GeForce GTX 770 JetStream. Notwithstanding the same memory chips, the memory frequency of the Zotac card is increased to 7200 MHz.
