Zotac GeForce GTX 650 Ti AMP! Edition 2GB (ZT-61103-10M)
Zotac offers as many as three GeForce GTX 650 Ti models and we’ve got the fastest of them: Zotac GeForce GTX 650 Ti AMP! Edition. There’s information about the card and Nvidia technologies implemented in it on the front and back of its small cardboard box.
There’s nothing special about the accessories which include a video interface adapter, a power cable, a CD with drivers and some documentation.
The made-in-China product costs $169.9. The warranty period is 2 years.
The Zotac GeForce GTX 650 Ti AMP! Edition seems to be the most beautiful graphics card in this review. The sculpted anodized metallic casing and the bright orange fan that sits on top of an aluminum heatsink make this graphics card very attractive.
The embellishments didn’t affect the size of the card which is 145x100x38 mm. There are memory chips on the reverse side of the PCB. Instead of one mini-HDMI, there are two standard HDMI outputs.
The Zotac GeForce GTX 650 Ti AMP! Edition also has two DVI outputs and a 6-pin power connector:
Unlike the other graphics cards in this review, the Zotac is recommended to be used with a 450 rather than 400-watt PSU.
The Zotac GeForce GTX 650 Ti AMP! Edition has a reference PCB but seems to have four power phases, two of which are responsible for the GK106 GPU.
After removing the generous amount of thermal grease, we can learn that the GPU was manufactured on the 34th week of 2012. It is revision A1.
The GPU is clocked at 1033 MHz in 3D mode, which is 11.3% higher than the reference card’s and equal to the Gigabyte’s GPU frequency. The EVGA is somewhat faster in terms of GPU clock rate.
The PCB carries eight memory chips, just like the three previous cards. The total amount of memory is 2 gigabytes.
Zotac doesn’t mind pre-overclocking graphics memory, therefore the GeForce GTX 650 Ti AMP! Edition clocks its memory chips at 6200 MHz (+14.8%) for a peak bandwidth of 99.2 GB/s.
The heatsink of the Zotac cooler is similar to those of the Nvidia and EVGA cards, remaining effectively a chunk of aluminum.
Thanks to the more advanced Everflow T129215SH fan, the GPU is cooled better than on the Nvidia and EVGA cards.
Auto fan mode
Maximum fan speed
In the automatic fan regulation mode, when the fan worked at only 23% of its maximum speed, the GPU was 58°C hot. At 100% fan speed, the GPU temperature wasn’t higher than 52°C. The Gigabyte remains unrivalled, but the Zotac is quite a cold card, too.
Our overclocking attempt was limited to increasing the GPU clock rate by 50 MHz. Our Zotac GeForce GTX 650 Ti AMP! Edition would hang up at higher frequencies. The memory frequency could be increased by 960 MHz.
The overclocked Zotac worked at 1083/7160 MHz:
Comparing the four GeForce GTX 650 Ti cards we’ve overclocked in this review, the EVGA has the highest GPU clock rate (1127 MHz) and the reference Nvidia card has the highest memory clock rate (7200 MHz).
The peak GPU temperature of the overclocked Zotac was 61°C.
