According to STE's press release the processor is actually dual-core running in either high performance or power save mode: "This is achieved by transistor-level electrical bias switching to allow each of two physical cores to run in two different modes, creating an electrically-enabled quad core."
Quoted from http://www.stericsson.com/press_releases/L8580_eQuad.jsp the section Notes to Editors, eQuad.
Wait to see the stories of
1) STE beat Qualcomm and Nvidia in the near future.
2) STM+GF(FDSOI camp) beat SAMSUNG+GF+UMC(IBM camp) and TSMC in Bulk CMOS and FINFET.
Look foreward to seeing more evidence soon.
Well done STE!
The key achievement here is the ability to operate with a so wide voltage range (0.6V to more than 1.1V I guess).
Also, low voltage operation is the key for low power (CV^2).
This is made possible by FD-SOI technology. I would like to see performance (and power) figures at lower than 0.6V, which is not achievable in bulk CMOS.
