I'm taking some history lessons and doing some math for an hour now Here is what I found :
Back in 2010, with Fermi Architecture, 480M performance was about 40% of desktop 480.
In 2012, with Kepler architecture, 680M performance was about 60% of desktop 680.
In 2014, with Maxwell architecture, 980M performance was about 80% of desktop 980.
GTX 1080 shows more than 70% fps boost over GTX 980.
If 1080M performance is about 80% of desktop 1080, then it means 1080M is 30% more powerful than desktop 980!
With same calculations 1070M is as powerful as desktop 980.
I'm looking forward to this.
