A Closer Look


ZOTAC's dual-fan cooler uses a copper base and two heatpipes to keep the card cool.


Once we remove the main heatsink assembly, we see two smaller heatsinks. One provides cooling for the memory chips on one side of the board and the other removes heat from the voltage regulation circuitry.


The card requires a single 6-pin PCI-Express connector. This power configuration is good for up to 150 W of power draw.


The GDDR5 memory chips are made by Samsung and carry the model number K4G20325FD-FC03. They are specified to run at 1500 MHz (6000 MHz GDDR5 effective).


ZOTAC uses an OnSemi NCP5395 voltage controller on their card. It does not provide software voltage control via I2C or any monitoring features.


NVIDIA's new GK106 processor is produced on a 28 nm at TSMC, Taiwan. The transistor count is 2.54 billion.
