A Closer Look
EVGA's thermal solution uses six heatpipes.
Once the main cooler is removed, you can see a second metal plate that cools the memory chips and voltage regulation circuitry.
The backplate is made from metal and comes with an EVGA cutout. Note that the print says GTX 1080, which is only the case with early EVGA GTX 1070 cards since there was apparently some kind of mixup with the backplates. EVGA tells me retail cards have the correct backplate.
EVGA has kept the 8-pin power input of the reference design. This configuration is specified for up to 225 watts of power draw.
NVIDIA's Pascal is introducing a new voltage controller by uPI, the uP 9511P. Its exact feature set is currently unknown.
The GDDR5 memory chips are made by Samsung and carry the model number K4G80325FB-HC25. They are specified to run at 2000 MHz (8000 MHz GDDR5 effective). This is the biggest change compared to the GTX 1080, which uses GDDR5X memory.
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, with a transistor count of 7.1 billion and a die size of 314 mm².
