Plot of transistor counts against dates of introduction. The curve shows counts doubling every two years.

The transistor count of a device is the number of transistors in the device. Transistor count is the most common measure of integrated circuit complexity. According to Moore's Law, the transistor count of the integrated circuits doubles every two years. On most modern microprocessors, the majority of transistors are contained in caches.

As of 2012, the highest transistor count in a commercially available CPU is over 2.5 billion transistors, in Intel's 10-coreXeonWestmere-EX.

Xilinx currently holds the "world-record" for an FPGA containing 6.8 billion transistors
