TSMC has started risk production of 5nm chips and expects to be ready to begin mass production in the first half of next year. This process promises much smaller chips (up to 45% area reduction), as well as performance gains (up to 15%) compared to the current 7nm chipsets. That's ignoring improvements in architecture, of course. For chipsets coming out later this year, TSMC has the 7nm+ process ready. It should offer 6-12% reduction in power consumption and 20% higher transistor density compared to the current 7nm process. There are plenty of customers lined up for 7nm+. TSMC is...
