So far, I haven't seen any direct comparison between Trinity mobile A10-4600M (which uses two Piledriver modules stripped of L3 cache) and desktop Bulldozer. The comparisons I've seen on the laptop end so far have all been comparing Llano mobile to Trinity mobile, which appears to be looking good (over 25% CPU performance increase with Trinity).
Trinity on both laptop and desktop will use one module (two cores) for the low-end and two modules (four cores) for the higher end. Or at least that's what we can expect: a dual-core and a quad-core for different price points.
Trinity on the desktop, on the other hand, has been compared to desktop Bulldozer here
, but keep in mind that Trinity has no L3 cache and will certainly be slower to some extent than the Piledriver-only, L3 cached CPU Vishera scheduled for Q3.Edited by computerdr - 4/26/12 at 1:13pm
