Circuit Board (PCB) Analysis

Unlike NVIDIA's Founders Edition boards, which implement MPS controllers, EVGA uses a pair of UPI 9511R controllers to manage the GPU voltage.

GPU Voltage, VRM Configuration

GPU voltage uses 19 power phases.

EVGA is using DrMOS components throughout the VRM.

Memory Chip Voltage Controller
Memory Voltage, VRM Configuration

Memory voltage uses a three-phase design and is generated by another UPI 9511R.

Graphics Card Memory Chips

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.

Graphics Chip GPU

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.
