Trinity is being aimed at ultrathin notebooks (not to be confused with Intel Ultrabooks), smaller form factor desktops and All-in-Ones, though traditional mainstream laptops and desktops will also see Trinity APUs. AMD will be launching five APUs today. The A10-4600M, A8-4500M, and A6-4400M are aimed at larger, mainstream notebooks, while the A10-4655M and A6-4455M are destined for sleeker ultrathin models.
AMD’s Trinity APUs will mark the debut of the company’s Piledriver microarchitecture, the successor to the ill-received Bulldozer. Trinity is still based on a 32nm process — Intel, by contrast, recently moved to 22nm with Ivy Bridge. Trinity’s die size is actually a bit larger than Llano’s: 246 square millimeters, compared to the first generation APU’s 228 square millimeters. Trinity also features a higher transistor count at 1.3 billion, but dials the TDP for its notebook variants down to 17W for dual-core CPUs, and 35W for quad-core CPUs, the same as Ivy Bridge — Llano APUs required 35W and 45W for dual- and quad-core, respectively. Desktop Trinity remain at the same 65 to 100W of its Llano predecessors. AMD claims that the dual-core Trinity APU will perform at the same level as the dual-core Llano APU, effectively doubling the performance per watt with the new generation. AMD also claims that Trinity notebooks can expect as 12 hours of battery life (when idle) on their energy efficient Piledriver cores.
