What are we talking about?
Intel Centra l Proces s ing Units
- Intel has been producing cpus s ince the 4-bit 4004 in 1971 to the modern day 6th generation models in 2015 (coming up on 2016).
- Focus ing on 6th generation of intels new CPU architectues : Broadwell and Skylake

Overview Broadwell - Intel’s primary objective when creating Broadwell was to create a mobile,
low-power CPU des igned to decrease battery consumption with minimal los s of performance.
- The new des ign was built us ing the 14nm Finfet lithography. The mos t recent des igns used a 22nm mos fets . The new Finfets require les s power to keep on.
- Broadwell will not completely replace the range of Haswells - Broadwell is the ‘Tick’ in Intel’s ‘Tick-Tock’ des ign philosophy. - Released in Summer of 2014

M-5Y70 (Broadwell) vs i7-4600U (Has well)
- With all other things constant there is an increase in operating frequency/TDP efficiency of 263%
- Battery Life+ at a reasonable cost of performance for the average, non-gaming user*

Overview Skylake - The ‘Tock’ represents a new architecture - Released September 2015 (lower power m-core models ) - Brings greater CPU and GPU performance - A fresh architecture. There are a few high end models , but overall there
hasn’t been any s ignificant improvement in anything but power efficiency.

Broadwell vs Skylake - Skylake is ditching the FIVR (Voltage regulator) used to consolidate a ll
incoming voltages . This is likely due to the effectivenes s of a s ingle regulator doesn’t jus tify the cos t.

What is a FinFet? - Developed by researchers from the Univers ity of California , Berkeley - Conducting channel is wrapped by thin s ilicon known as the “fin”
- Provides better electrical control over the channel - Which reduces current leakage and other short-channel effects
