In the semiconductor industry, Moore's name no wonder known to everybody, this is a law of Intel co-founder Gordon Moore made in 1965, originally refers to a semiconductor chip transistor density doubling every year, double the performance, later repair every 2 years transistor double double performance.
Over the past 50 years, Moore's Law has guided the development of the semiconductor industry, Tick-Tock strategy proposed a few years ago Intel Moore's Law is actually a period of two years to upgrade a structure, a two-year upgrade process, alternately.
However, Tick-Tock the 14nm node on the failure, Intel has polished the 14nm process for nearly five years, 10nm process before mass production in June this year, spent on Ice Lake tenth generation Core Duo processor, but so far only mobile high-performance version of the 10nm processors until at least 2020.
In recent years, about the end of Moore's Law has been the topic of discussion of the industry, in addition to Intel does not want to admit that other companies in the industry are basically identified over Moore's Law, after the 10nm node has been completely unable to guide the development of the chip.

At the opening of yesterday SIGGRAPH2019 conference, former Chief Architect Jim Keller AMD Zen also made a related presentation, although he now works as a general manager of Intel Silicon Valley, vice president TSCG sector, but unceremoniously quoted rival NVIDIA CEO Jen-Hsun Huang's point of view - Moore's Law is dead.
After Moore's Law is over, the industry what the law to guide summarizes chip development? Keller's speech from the point of view, he referred to the two laws, one of Bell's Law, pointed out that computing device to enhance the performance every 10 years, 10 times, 10 times cheaper price, while a small volume of 10 times.
In addition to Bell's Law, as well as Raja's Law - The Raja refers to the former head of AMD RTG, now Intel senior vice president Raja Koduri, he also put forward the law with their own name.
Raja's Law refers to the computing device will be a new price every 10 years, the performance of the previous generation 10 times, was originally a single-core CPU, followed by multi-core CPU, then followed GPU, now it is a variety of AI chip.
