Circuit Board (PCB) Analysis

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


ASUS is using Vishay Siliconix SiC654 DrMOS components for the GPU VRM, which are rated for 50 A.


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


For memory, the same Vishay SiC654 DrMOS chips are used as on the GPU VRM.


The GDDR6X memory chips are made by Micron and carry the model number D8BWW, which decodes to MT61K256M32JE-19G:T. They are specified to run at 1188 MHz (19 Gbps GDDR6X effective).


NVIDIA's GA102 graphics processor is the company's second Ampere architecture chip; 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.
