>i>Lower CPU clock speeds aren't entirely unexpected given the fact that Piledriver shares the processor die with a beefy Radeon GPU based on AMD's 6000-series architecture. Bulldozer has no graphics sidekick, let alone one with DirectX 11 credentials.
Trinity's integrated Radeon purportedly features up to 384 ALUs and can run at speeds as high as 800MHz. The graphics component looks like it takes up close to half of the die. If the slides are legit, that die measures 246 mm², making it a little larger than Llano and quite a bit bigger than Ivy bridge. Ivy has more transistors, but it's fabbed on a smaller 22-nm process, while Trinity will be built using 32-nm technology.
