AMD has no plans in releasing Steamroller CPUs to replace FX Piledriver CPUs in 2014 which is quite a shame for such a company. Usually processor series gets replaced after every year. And since the Piledriver CPUs got released way back in October 2012, it was a must that Piledriver CPUs got replaced at least in 2014. But it seems like AMD has no interest in the desktop performance arena and might keep on releasing overclocked versions of Piledriver CPUs. The company has decided to focus more on APUs in 2014. A lot of AMD FX users, including me, were eagerly waiting for the release of Steamroller CPUs in the next year but it seems like AMD will keep on disappointing people which they have learnt on the day they released the Bulldozer CPUs.

No AMD Steamroller till 2015(may be). The leaked AMD product roadmap suggests that AMD may be set to step out of the performance consumer CPU market to concentrate solely on APU production.
