A Closer Look

Gigabyte's thermal solution uses six heatpipes and a large copper baseplate.


The backplate has a bunch of thermal pads to improve heat transfer.


One of the new features of this card is this slab of copper which is tightly stuck opposite of the GPU, on the other side of the PCB. Gigabyte promises it will improve thermal dissipation of the GPU, which we will test later.


Gigabyte upgraded the power input of their GTX 1080 to two 8-pins. This input configuration is specified for up to 375 watts of power draw.


The uP 9511 voltage controller is a new model for recent NVIDIA cards. It does not support voltage control via I2C.


The GDDR5X memory chips are made by Micron and are marked with "D9TXS," which decodes to MT58K256M32JA-100. These are specified to run at 1250 MHz (10,000 MHz GDDR5X effective).


NVIDIA's GP104 graphics processor is the first consumer chip using the Pascal architecture. It is produced on a 16 nm process at TSMC, Taiwan, and has a transistor count of 7.1 billion and a die size of 314 mm².
