In terms of computer systems that consist of numerous integrated circuits, the supercomputer with the highest transistor count as of 2016 is 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, has on the order of 100,000 transistors. 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 7 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 2022, the highest transistor count GPU is Nvidia's H100, built on TSMC's N4 process and totalling 80 billion MOSFETs. Īs of 2022, the largest transistor count in a commercially available microprocessor is 114 billion transistors, in Apple's ARM-based dual-die M1 Ultra system on a chip, which is fabricated using TSMC's 5 nm semiconductor manufacturing 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. 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). And in 1971 the first commercial microprocessor (the powerhouse of any electronic gadget) was 1,000 times bigger than today’s when it was released.The transistor count is the number of transistors in an electronic device. By 1947, the current type of transistor-the one that’s now just 14 nanometers across-was invented and it was 40 micrometers long (about 3,000 times longer than the current one). The first transistor was made in the year 1907 using vacuum tubes, which were typically between one and six inches tall (on average 100 mm). We still have some way to go before the first consumer device reaches the market, and progress takes time. When can I get a light-based laptop or smartphone? If we’re able to figure out how to do it-or even to use light-based transistors to enhance electronic ones-we could see significant performance improvement. A key challenge is making sure the new light-based chips can work with all the existing electronic chips. Scientists have demonstrated progress toward photonic chips in recent years. That means computers that are 20 times faster, a speed increase that would take about 15 years to achieve with current technology. On average photons can travel about 20 times faster than electrons in a chip. First, a photonic chip needs only a few light sources, generating photons that can then be directed around the chip with very small lenses and mirrors.Īnd second, light is much faster than electrons. However, for two reasons, we could keep chips the same size and deliver more processing power, shrink chips while providing the same power, or, potentially both.
