Transistor count

The transistor count is the number of transistors on an integrated circuit (IC). Transistor count is the most common measure of IC complexity, although there are caveats. For instance, the majority of transistors are contained in the cache memories in modern microprocessors, which consist mostly of the same memory cell circuits replicated many times. The rate at which transistor counts have increased generally follows Moore's law, which observed that the transistor count doubles approximately every two years. As of 2016^[update], the largest transistor count in a commercially available single-chip processor is over 7.2 billion—the Intel Broadwell-EP Xeon. In other types of ICs, such as field-programmable gate arrays (FPGAs), Intel's (previously Altera) Stratix 10 has the largest transistor count, containing over 30 billion transistors.

A microprocessor incorporates the functions of a computer's central processing unit on a single integrated circuit. It is a multipurpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and provides results as output.

The "second generation" of computers (transistor computers) featured boards filled with discrete transistors and magnetic memory cores.

A graphics processing unit (GPU) is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the building of images in a frame buffer intended for output to a display.

A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing.

Transistor count for generic logic functions is based on static CMOS implementation.
