A Closer Look

When disassembling Sapphire's Pulse, the first piece that will come off is the cooler's shroud, which houses the two fans.


The heatsink uses a copper base plate and two heatpipes. It also cools voltage regulation and memory chips.


The backplate is made from metal and will protect the card during handling and installation.


Sapphire is using a single 8-pin power connector. This input configuration is specified for up to 225 watts of power draw.


The NCP81022 is a very common voltage controller used on a large number of AMD designs.


The GDDR5 memory chips are made by Elpida and are marked W4032BABG-70-F. They are specified to run at 1750 MHz (7000 MHz GDDR5 effective).


The Radeon RX 570 uses the same Ellesmere GPU as the Radeon RX 470; each transistor is identical. The only difference is in the manufacturing process, which has been refined and now happens at Samsung and Globalfoundries. Transistor count is 5.7 billlion and die size is 232 mm².
