I'm guessing they will be shrinking the die down to 22nm ?
No, Intel is still out in front in terms of their Fab tech so companies like global foundries and TSMC are moving to 28nm.
trinity the 2nd generation of Apu's I'm guessing
does anyone know a ruff release date of the piledriver ?
Well we should be seeing piledriver cores in the new APU's so we should be able to get some idea of how the FX's will perform, but i dont expect to see 'pure' piledriver CPU's until the later part of this year seeing as how BD is not vey old at all.
