At the Mobile World Congress, ST-Ericsson demonstrated NovaThor L8580 highly-integrated smartphone platform with a 2.5GHz quad-core application processor and a multimode 4G/LTE advanced modem supporting carrier aggregation. Thanks to special burst mode technologies, the L8580 can increase its clock-speeds to up to 3.0GHz in cases when high performance is needed. The SoC is among the first products to be made using 28nm FD-SOI technology.
The initial commercial version of the NovaThor L8580 integrates a quad-core 2.5GHz processor cluster based on ARM Cortex-A9, Imagination PowerVR SGX544 graphics core running at 600MHz and an advanced multimode 4G/LTE modem supporting carrier aggregation on a single 28nm FD-SOI die. The NovaThor L8580 supports LTE-FDD, LTE-TDD, HSPA+, GSM and TD-SCDMA with downlink speeds up to 150Mb/s in the same chipset as well as VoLTE and HD voice.
“We focused on innovation on real world use cases and delivered a ModAp technology that lets applications run significantly faster – up to 35% faster CPU while GPU and multimedia accelerators run 20% faster. With the NovaThor L8580, ST-Ericsson is bringing speeds normally reserved for the PC market to mobile devices,” said Didier Lamouche, president and CEO of ST-Ericsson.
According to the company, NovaThor L8580 consumes 35% less power than rival architectures at comparable high frequencies. The L8580’s ground breaking 0.6V low power mode consumes 50% less power at 1GHz redefining the active standby experience for users of mobile devices while adding hours of battery life.
“Our next-generation NovaThor platform is creating a disruption for the wireless industry by combining some of the most advanced technologies on the market, including STMicroelectronics’ 28nm FD-SOI process technology, to deliver a real industry breakthrough in terms of speed, power consumption and overall performance,” said Mr. Lamouche.
The complete platform includes multimedia performance and pre-integrated connectivity with support for Bluetooth, GNSS (GPS+ GLONASS), FM, WLAN, WiFi Direct, Miracast and NFC. With ST-Ericsson’s connectivity solutions, CG2905 and CW1260, the platform comes optimized for wireless radio co-existence and low power consumption.
The NovaThor L8580 is pin-to-pin and Software compatible with ST-Ericsson’s first generation NovaThor 4G/LTE multimode platform the L8540.

It is NOT a quad core it is only a dual core. STE calls it "eQuad", because the two cores can run at very high clocks but also very low clocks with only 0.6v vcore. Thus you don't need to usa a big-little-core approach, where 2 small cores are combined with to big cores, hence they call it "equad".

Yes that is correct, the trick is in body back biasing to control Vts
