The consoles are going to have custom AMD Jaguar cores. The dual core and quad core Jaguar targets are tablets and low cost laptops / netbooks. The consoles will have custom Jaguar cores because the integrated graphics will be much more powerful (at least that's what I'm assuming) compared to the graphic cores in the dual and quad core versions of Jaguar. I suppose the console Jaguars are true 8 core CPUs, however, I have read some articles that speculated it was in fact two quad cores "glued" together. But that was a few months ago and I haven't seen anything else about that issue. Then again, I not particularly interested...
Anywaste, in terms of AMD's CPU architecture the Jaguar core is the least powerful. Then comes the Richland core for the A series APUs. Finally, there is the Piledriver core in the FX CPUs. AMD's competitor to Intel's Core i3/i5/i7 family is the FX series.
