AMD has already previewed the latest APU Trinity for desktops at Computex, but the launch is still a couple of months into the future. The first processors have now been listed at the AMD website, all in quad-core suits.
Trinity is the code name for AMD’s latest APU architecture contaiing two fine-tuned Bulldozer modules called Piledriver, and the Terascale 3 graphics architecture that was used in HD 6900. Trinity was launched about a month ago for notebooks, but desktops will take until Q3. The first four models have now been listed at the AMD website.

Common for all models is that they all get two Piledriver modules for a total of four cores and 4 MB L2 cache. The A10 models have six VLIW clusters for 384 Radeon cores, while A8 settles for four clusters and 256 Radeon cores. Compared to the retail CPU FX-4100, with four cores at 3.6 GHz and 3,8 GHz Turbo with 95W TDP it looks like AMD has managed to reduce the energy consumption quite a lot with the Piledriver architecture.
It is still too soon to say how Trinity performs in desktops, but we will wait until we have it in the lab to give a run in our test bench. It did do well in the mobile segment though.
Why is Trinity for desktops taking so long?
It is still unclear why Trinity is taking so long for desktops, but AMD is not having any manufacturing problems. One reason could be that it wants to empty outy out stock of Llano processors, or that it simply prioritizes notebooks before desktops and want to build capacity before launch. The launch will happen in September-October, while OEM partners will get a taste the weeks before. LIke the case with Llano, we can expect dual-core models at a later date.
