Actually you do. The branding is called FinFlex, but the upshot is that you can use different FETs for different parts of a circuit. So some critical timing bottleneck blocks could be built with performance optimized FETs and other blocks can optimize for low power.
The numbers from TSMC for N3E are +18% speed improvement at same power, -34% power reduction at same speed, and 1.7x density improvement.

>Also, are these Apple's numbers?
Ha ha. That's funny. Does Apple ever release any numbers prerelease?
