Brian Krzanich, former CEO of Intel, also noted that “our cadence today is closer to two and a half years than two”. ![]() As a matter of fact, processor architects reported already 10 years ago that semiconductor advancement has slowed industry-wide below the pace predicted by Moore's law. It’s seems clear that at some point we’ll hit physical limitations when it comes to transistor scaling, despite our best efforts to come up with new methods for packing stuff even denser on a silicon wafer. Whereas chips in the 1970s only had a few thousand transistors, the 1 billion mark was hit in 2006 – and now we’re indeed packing 60 billion transistors into a chip. Let’s take a look at how the transistor count in processors has evolved up until 2019. While Moore did not use empirical evidence in forecasting that the historical trend would continue, his prediction held since 1975 and has since become known as a "law”. In 1975, looking forward to the next decade, he revised the forecast to doubling every two years, a compound annual growth rate (CAGR) of 40%. The observation is named after Gordon Moore, the co-founder of Fairchild Semiconductor and CEO and co-founder of Intel, who in 1965 posited a doubling every year in the number of components per integrated circuit, and projected this rate of growth would continue for at least another decade. Here’s what Wikipedia has to say about it: In reality, Moore’s law is the observation that the number of transistors in a dense integrated circuit (IC, or a “chip”) doubles about every two years. that processor speeds, or overall processing power for computers, will double every two years. Many are familiar with Moore’s law, which often is heard in its simplified version, i.e. That in turn results in several benefits, such as faster processing speeds and increased memory capacity. The basic rule is that with more transistors, a processor can perform increasingly more complicated instructions than before. Since each transistor can be in two distinct states, it can store two different numbers, zero and one. A chip can contain hundreds of millions or even billions of transistors, each of which can be switched on or off individually. ![]() Transistors are essential in processors because they work as switches. This will continue to be the case until we adopt a new processor architecture, for example through quantum processors.Ī “traditional” processor is simply “the electronic circuitry within a computer that executes instructions that make up a computer program” and traditional computing relies on zeros and ones. In other words, the form, design, and implementation of chips have changed over time, but their fundamental operation remains almost unchanged. But what does this stunning transistor count mean in practice?įirst of all it’s good to remember that while computing power has grown exponentially, the basic architecture of computer chips, such as central processing units (CPUs), hasn’t changed much during the past 65 years. However big or small a computer chip is in actual physical size, 60 billion transistors sounds like a lot. ![]() This Bristol based “startup”, founded in 2016 and now valued at $2bn, is taking on Nvidia with a new chip designed specifically for running advanced AI algorithms. Today I read that Graphcore, the AI chip maker from the UK, unveiled a new computer chip that packs a remarkable 60 billion transistors and almost 1,500 processing units into a single silicon wafer.
