Intel might be sticking to the familiar Kaby Lake architecture for the eight generation of its Core chips, but the its internal testing looks pretty promising as far as performance goes. The company says the chips are capable of a 40-percent increase over their predecessors — and even more notable for those finally ready to upgrade an old system: about double the performance of a five year old device.

That’s a pretty impressive boost in a single generation — and even more significant than the already notable 30-percent boost the company promised when it teased the refresh during Computex in May. The performance boost comes as laptop makers are expected to increasingly push the envelope with their systems.
