A Closer Look
The Inno3D triple-slot cooler uses four heatpipes that quickly transport heat from the GPU core to the heatsink area.
We find a metal heatspreader that cools secondary components, like voltage regulation circuitry and memory chips, below the main cooler. The memory chips on the other side of the card are not cooled.
The card requires two 6-pin PCI-Express power cables for operation. This power configuration is good for up to 225 W of power draw. This is a deviation from all other GTX 650 Ti Boost cards. The others all only have a single 6-pin power connector. Our testing shows no gains we could attribute to the dual-connector approach. The card actually never needed more power than what a single connector could have delivered alone. I also tried to see whether the card would work with just a single power cable connected. That is not the case.
Inno3D uses an OnSemi NCP5395 voltage controller. We have seen this controller on many designs before. It is a cost-effective solution that does not provide any I2C, so advanced monitoring is not possible.
The GDDR5 memory chips are made by Hynix and carry the model number H5GQ2H24AFR-R0C. They are specified to run at 1500 MHz (6000 MHz GDDR5 effective).
NVIDIA's GK106 processor is produced on a 28 nm at TSMC, Taiwan. The transistor count is 2.54 billion.
