Circuit Board (PCB) Analysis

GPU Voltage, VRM Configuration
GPU Chip Voltage Controller

GPU voltage is a massive 20-phase design, managed by a Monolithic Power Systems MP2891 controller, which also handles memory voltage.


Monolithic MP86957 DrMOS components are used for GPU voltage; they are rated for 70 A of current each.

Memory Voltage, VRM Configuration

Memory voltage is a three-phase design, managed by the same MP2891 that's uses for GPU voltage.


For memory, Monolithic MP86957 DrMOS with a 70 A rating are used again.

Graphics Card Memory Chips

The GDDR6X memory chips are made by Micron and carry the model number D8BZC, which decodes to MT61K512M32KPA-21:U. They are specified to run at 1313 MHz (21 Gbps effective).

Graphics Chip GPU

NVIDIA's AD102 graphics processor is the company's flagship Ada Lovelace GPU. It's the world's first 5 nanometer GPU, built at TSMC Taiwan, with a transistor count of 76.3 billion and a die size of 608 mm².
