As of 2020, the highest transistor count in any IC chip is a deep learning engine called the Wafer Scale Engine 2 by Cerebras, using a special design to route around any non-functional core on the device it has 2.6 trillion MOSFETs, manufactured using TSMC's 7В nm FinFET process. As of 2019, the highest transistor count in any IC chip was Samsung's 1 terabyte eUFS ( 3D-stacked) V-NAND flash memory chip, with 2 trillion floating-gate MOSFETs ( 4 bits per transistor). As of 2020, the highest transistor count in a graphics processing unit (GPU) is Nvidia's GA100 Ampere with 54 billion MOSFETs, manufactured using TSMC's 7В nm process. The rate at which MOS transistor counts have increased generally follows Moore's law, which observed that the transistor count doubles approximately every two years.ДЄs of 2021, the largest transistor count in a commercially available microprocessor is 57 billion MOSFETs, in Apple's ARM-based M1 Max system on a chip, which is fabricated using TSMC's 5 nm semiconductor manufacturing process. It is the most common measure of IC complexity (although the majority of transistors in modern microprocessors are contained in the cache memories, which consist mostly of the same memory cell circuits replicated many times). It typically refers to the number of MOSFETs (metal-oxide-semiconductor field-effect transistors, or MOS transistors) on an integrated circuit (IC) chip, as all modern ICs use MOSFETs. The transistor count is the number of transistors in an electronic device.
