The best budget card for 1080p gaming?
While the Nvidia reference card was rather small to look at, the Zotac AMP! Edition treatment has beefed up a few things on this card.
First of all you’ll notice that it has two full slots on the backplate instead of just one, while the Zotac card has two full-sized HDMI ports compared to one mini-HDMI port on the reference Nvidia card. The heatsink is also bigger on the Zotac card, covering a larger area of the PCB, while the fan itself is 85mm, compared to 75mm on the reference Nvidia GTX 650Ti.
Of course, the Zotac GTX 650Ti AMP! Edition needs these changes because of the significant factory overclock applied. The Core clock on the Zotac is set to 1033MHz compared to 928MHz on Nvidia, while the memory clock is set to 6200MHz compared to 5400MHz on Nvidia. That’s an 11% increase on Core clock speeds and 15% on memory clock speeds. Additionally the Zotac GTX 650Ti AMP! Edition also features 2GB of memory compared to 1GB on reference Nvidia GTX 650Ti.
All of this comes at the cost of $189, which is dangerously close to the AMD HD 7850 cards that easily matches the performance of the GTX 660.
