Circuit Board (PCB) Analysis

GPU Chip Voltage Controller
GPU Voltage, VRM Configuration

EVGA is using a very simple 3-phase VRM to power the GPU, controlled by an On Semi NCP81611 controller. These are direct phases without any doubling (which the PCB has provision for). Interestingly, EVGA chose premium On Semi DrMOS components, which are passively cooled under the cooler's airflow.

Memory Chip Voltage Controller
Memory Voltage, VRM Configuration

The memory VRM is 2-phase and managed by a UPI uP1666Q controller.

Graphics Card Memory Chips

The GDDR6 memory chips are made by Micron and carry the model number D9WCW, which decodes to MT61K256M32JE-14:A. They are specified to run at 1750 MHz (14 Gbps GDDR6 effective).

Graphics Chip GPU

NVIDIA's TU116 graphics processor is the company's first chip with the Turing architecture that does not include Tensor cores or ray-tracing acceleration. It is produced on a 12 nm process at TSMC, Taiwan and has a transistor count of 6.6 billion with a die size of 284 mm².
