Computer chips have stopped getting faster: The regular performance improvements we’ve come to expect are now the result of chipmakers’ adding more cores, or processing units, to their chips, rather than increasing their clock speed.
Computer chips keep getting faster because transistors keep getting smaller. But the chips themselves are as big as ever, so data moving around the chip, and between chips and main memory, has to travel just as far. As transistors get faster, the cost of moving data becomes, proportionally, a more severe limitation.
No computer works as efficiently as the human brain – so much so that building an artificial brain is the goal of many scientists.
Despite Moore's Law, the speed of computer chips has stagnated over recent years, with manufacturers routinely adding additional cores to increase processing power.
Security concerns usually get in the way of adopting new non-volatile main memory (NVMM) technology. Researchers at North Carolina State University may have fixed that problem.
University of Illinois scientists have discovered that graphene transistors have a nanoscale cooling effect.
Researchers at North Carolina State University have developed a method of integrating gallium nitride (GaN) sensors and devices directly into silicon-based computer chips.
