ST-Ericsson uncloaks 2.5GHz Jekyll & Hyde smartphone chip
The CES 2013 show floor may be crammed with smartphones, tablets, and other ARM-powered gadgets, but there's more news from the show than just the gadgets themselves. There's also a new chip that can power them – namely a new 2.5GHz part from ST-Ericsson. "Building on the architecture of our first generation NovaThor L8540 LTE …

Quad-core, not dual-core.
Just going out on a limb here, but I hazard a random guess that a CPU cluster called "eQUAD" would have FOUR CPU cores, not two. Also their diagram shows four cores.
Re: Quad-core, not dual-core.
You haven't read the marketing blub.
"eQuad" is a name they've given to a dual core processor where each core can be run in either a high performance or a low power mode. This is achieved by electrical biasing the transistors.
So two cores, each with two modes. Hence the "eQuad".
Re: Quad-core, not dual-core.
Doesn't explain the marketing diagram showing four squares, or cores. Previous diagrams clearly show two cores where there are two.
On a 28nm node you might as well do all four cores. Maybe two of the cores are HP, and two are LP, and that's how it works.
