Circuit Board (PCB) Analysis

The GPU VRM is 4-phase, controlled by a OnSemi NCP 81611 controller.


The memory VRM is single-phase, managed by a OnSemi NCP 81278.


The GDDR5 memory chips are made by Micron and carry the model number D9VVR, which decodes to MT51J256M32HF-80:B. They are specified to run at 2000 MHz (8 Gbps GDDR5 effective).


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.

Unlike previous Turing GPUs, which separated "non-OC" chips and chips for factory overclocking by adding an "A" designation on the chip variant, all TU116 chips on the GTX 1660 Ti are TU116-400 (without the A) and can be used for OC cards.
