Apple has used WWDC 2022 to announce its second-generation Apple Silicon chips in the M2 processor with more performance per watt than the M1.
As predicted, Apple has unveiled the M2 processor, with over 20 billion transistors, and starting off a next generation of chips.
"We use those transistors to enhance every feature of the chip, starting with the memory controller," said Johny Srouji, senior vice president of hardware technologies, "which delivers 100 gigabyte per second of unified memory bandwidth, which is 50% more than M1 for even greater performance."
"The performance cores are faster and feature a larger cache," he continued, "efficiency cores have been significantly enhanced for even greater performance gains."
Apple says that M2 "delivers 18% greater performance" than M1, and has "nearly two times faster performance" than equivalent PC laptops, "while using a quarter of the power."
"The 10-core GPU delivers a big boost in graphics performance and two delivers up to 25% higher graphics performance at the same power level as M1," said Srouji. "The GPU in M2 delivers 2.3 times faster performance at the same power level.'
Srouji says that this means "much higher performance per watt" yet also enables the system "to run cooler with exceptional battery life."
The new M2 also features a next generation of the Secure Enclave, plus an advanced neural engine. It also provides a higher bandwidth video decoder which means M2 can play back multiple streams of 4K and 8K video.
"The fact that we're already starting our next generation of Apple silicon for the Mac is remarkable," said John Ternus, senior vice president of hardware engineering.
