Circuit Board (PCB) Analysis
The GPU VRM is 19-phase, controlled by two OnSemi NCP8610 controllers.
OnSemi NCP302150 DrMOS chips pull the GPU power phases.
Memory is a 3-phase setup pulled by an OnSemi NCP81610 controller.
OnSemi NCP302150 DrMOS make another appearance, this time working the memory phases.
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.
