Circuit Board (PCB) Analysis
The GPU VRM is 18-phase, controlled by two Monolithic Power Systems MP2888A controllers.
For GPU voltage, Infineon TDA21570 DrMOS are used, which are rated for 70 A.
Memory voltage uses a 4-phase design and is generated by a UPI uP9628P controller
OnSemi NCP303151 DrMOS are used for memory voltage. These are capable of up to 50 A.
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.
