AMD's entry-level APU (accelerated processing unit) offering is rumored to receive an updated in Q3 with the release of a new Ontario model called C-60 which features the same specs as the currently-available C-50 plus en extra - a Turbo mode for both the x86 cores and the integrated graphics.
The C-60 has its two x86 Bobcat cores running at a default 1.0 GHz but with Turbo they could go up to 1.33 GHz during intensive tasks. The Radeon HD 6290 works at 276 MHz and in Turbo mode it would reach 400 MHz.
Since the C-60's TDP is still 9W, same as the C-50's, Turbo may only work on one component (either the x86 cores or the GPU) at a time. The C-60 may be prepared for the back-to-school period to taken on netbooks powered by Intel's new Atom N570 dual-core so expect more info about it this summer.
