A Closer Look
NVIDIA's cooler has a complex heatsink-base that uses a vapor-chamber technology to cool the GPU, memory chips, and all secondary components. A backplate is not included.
The card requires a 6-pin and 8-pin PCI-Express power connector. This configuration is good for up to 300 W of power draw.
NVIDIA uses the same OnSemi NCP4206 voltage controller on the GTX 780 Ti as on the Titan/GTX 780. Latest overclocking software supports NCP4206 specific voltage control.
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.
