Circuit Board (PCB) Analysis

The ASUS RTX 3080 TUF Gaming OC uses a pair of UPI uP9512R 8-phase VRM controllers, which puts out a 16-phase VRM for the GPU.


ASUS is using Vishay Siliconix SiC641 DrMOS components throughout this VRM solution.


The memory power is a 4-phase setup pulled by a uP9512S buck controller.


The GDDR6X memory chips are made by Micron and carry the model number D8BGW, which decodes to MT61K256M32JE-19:T. They are specified to run at 1188 MHz (19 Gbps GDDR6X effective).

GDDR6X doubles the data rate once again over GDDR6. It no longer transmits one bit of information by setting the voltage to either "on" or "off", but instead sends two bits of information at the same time by using four different voltage levels.


NVIDIA's GA102 graphics processor is the company's second Ampere architecture chip, and the first one targeted at GeForce gamers. It is produced on a 8 nanometer process at Samsung and has a transistor count of 28 billion with a die size of 628 mm².
