A Closer Look
EVGA's heatsink uses six heatpipes for maximum heat transfer.
A plate has been placed on top of the card, below the heatsink, to cool voltage regulation circuitry and memory chips.
The card requires two 8-pin PCI-Express power connectors. This configuration is good for up to 375 W of power draw.
This little switch lets you switch between the normal BIOS and a BIOS optimized for liquid nitrogen usage. The dual BIOS feature also serves as backup in case something goes wrong with your BIOS flash - switch to the other BIOS and you are up and running again.
You'll find a header for EVGA's EVBot, an external addon controller that allows you to easily adjust the card's voltage, near the power connectors. EVBot is unfortunately not available for purchase at the moment. EVGA claims supply issues.
The CHiL 8318 voltage controller has been used on several GTX 670, 680, 770 and 780 custom designs. It offers many voltage control and monitoring features.
The GDDR5 memory chips are made by SK Hynix and carry the model number H5GQ2H24AFR-R2C. They are specified to run at 1750 MHz (7000 MHz GDDR5 effective).
NVIDIA's GK110 graphics processor was first introduced as a Tesla-only product for powering demanding GPU compute applications. NVIDIA is now also selling it as a GeForce GPU. It uses 7.1 billion transistors on a die size we measured to be 561 mm². The GPU is produced on a 28 nanometer process at TSMC, Taiwan.
Please note that the GPU on the GTX 780 Ti is marked "B1", whereas previous cards used "A1". Whether this is really an updated GPU or simply a different label is not known. NVIDIA has not discussed A1 vs. B1 GPUs with the press.
