Charlie Demerjian from SemiAccurate writes it now looks like AMD will have no new APU in 2013 because Kaveri is further delayed.
Kaveri is the successor to the current Trinity APU, it replaces the chip's Piledriver cores with Steamroller cores and replaces the VLIW4 based integrated graphics with GCN. It's a generational advance on the APU roadmap that was originally supposed to arrive about now, but in July the chip got delayed to the first half of 2013 to make it more competitive against Haswell, because Intel's new chip is much more than just a generational advance.
Unfortunately for AMD, it seems things once again didn't work out as planned and according to SemiAccurate the Kaveri APU is unlikely to see the light of day until 2014 if it is still alive. That would put the chip 18 months late, into the headlights of Intel's next tick (Broadwell).
