For example, the last DEC Alpha chip uses 90% of its transistors for cache.The use of transistors for the construction of logic gates depends upon their utility as fast switches. The number of transistors used for these cache memories typically far exceeds the number of transistors used to implement the logic of the microprocessor (that is, excluding the cache). Modern microprocessors typically include on-chip cache memories. The 4-bit Intel 4004, released in 1971, was the first single-chip microprocessor. ![]() However, it was classified by the Navy until 1998. It was a multi-chip microprocessor, fabricated on six MOS chips. Navy's F-14 Tomcat fighter in 1970, is considered by its designer Ray Holt to be the first microprocessor. The 20-bit MP944, developed by Garrett AiResearch for the U.S. The development of MOS integrated circuit technology in the 1960s led to the development of the first microprocessors. It is a multi-purpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and provides results as output.

This subsection needs additional citations for verification. Įstimates of the total numbers of transistors manufactured: Ionic transistor chips ("water-based" analog limited processor), have up to hundreds of such transistors. The first carbon nanotube computer had 178 transistors and was a 1-bit one-instruction set computer, while a later one is 16-bit (its instruction set is 32-bit RISC-V though). Early experimental solid-state computers had as few as 130 transistors but used large amounts of diode logic. In terms of computer systems that consist of numerous integrated circuits, the supercomputer with the highest transistor count as of 2016 was the Chinese-designed Sunway TaihuLight, which has for all CPUs/nodes combined "about 400 trillion transistors in the processing part of the hardware" and "the DRAM includes about 12 quadrillion transistors, and that's about 97 percent of all the transistors." To compare, the smallest computer, as of 2018 dwarfed by a grain of rice, had of the order of 100,000 transistors. Wafer-scale design of 84 exposed fields (dies)ĭual-die SoC entire M2 Ultra is a multi-chip module Stacked package of sixteen 232-layer 3D NAND dies The highest transistor count in a consumer microprocessor is 134 billion transistors, in Apple's ARM-based dual-die M2 Ultra system on a chip, which is fabricated using TSMC's 5 nm semiconductor manufacturing process. Īs of 2023 highest transistor count GPU is AMD's MI300X, built on TSMC's N5 process and totalling 153 billion MOSFETs. It has 2.6 trillion MOSFETs in 84 exposed fields (dies) on a wafer, manufactured using TSMC's 7 nm FinFET process. The highest transistor count in a single chip processor is that of the deep learning processor Wafer Scale Engine 2 by Cerebras. However, being directly proportional to the area of a chip, transistor count does not represent how advanced the corresponding manufacturing technology is: a better indication of this is the transistor density (the ratio of a chip's transistor count to its area).Īs of 2023, the highest transistor count in flash memory was Micron's 2 terabyte ( 3D-stacked) 16-die, 232-layer V-NAND flash memory chip, with 5.3 trillion floating-gate MOSFETs ( 3 bits per transistor). 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. ![]() It is the most common measure of integrated circuit 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). The transistor count is the number of transistors in an electronic device (typically on a single substrate or "chip").
