Technical Data / Specifications

You might be expecting this, with the nVidia GeForce GTX 650 Ti Boost you get a reference card with reference clocks, a reference PCB and a reference cooler. The ASIC quality measured on our sample was 71.6 %.
About ASIC quality:



Looking at clock speeds we see the GTX 650 Ti Boost is sharing the same frequencies as its great sister the GTX 660. Therefore the GPU runs at 980 MHz with a typical boost of 1'033 MHz and the GDDR5 memory is clocked at 1'500 MHz (6'000 MHz effective).
The card also features nVidia's Boost 2.0 technology. In our case when the GPU temperature was below 50°C the card was clocking itself up to 1'084 MHz. Above 50°C the GPU clock went down to 1'071 MHz and above 70°C to 1'058 MHz.

Something else this GTX 650 Ti Boost shares with the GTX 660 is the PCB. When you take a closer look at the PCB you see that it's identical. Therefore you get an analogue power design with five phases, where the GPU gets four phases and the memory gets one phase.
The voltage regulation chip used for the GPU power stage is a NCP5395G from ON Semiconductor. On the memory power stage you find an APL1117 from ANPEC.



This graphics card even features the same cooler you find on the GTX 660 reference cards. It comes with an aluminium fin stack and a copper base. The whole thing is cooled by a radial/blower-type fan.



The memory chips used are made by Samsung and carry the model number K4G20325FD-FC03. They are specified to run at 1'500 MHz (6'000 MHz effective).
