A little earlier, Samsung refreshed its Series 5 line of performance notebooks with Intel Core "Ivy Bridge" processors. It created a new branch, powered by AMD "Trinity" accelerated processing units (APUs), which pack up to four x86-64 cores, Radeon HD 7600M series graphics, and dual-channel DDR3 IMCs. Samsung currently has two models that are Trinity-powered, the Series 5 13.3-inch (NP535U3C-A01US), which is driven by AMD A6-4455M quad-core APU (2.10 GHz); and the Series 5 14-inch (NP535U4C-A01US), driven by AMD A10-4655M quad-core APU (2.80 GHz). Both models come with 4 or 8 GB dual-channel DDR3 memory and 500 or 750 GB HDD standard, with other features being identical to those of its Ivy Bridge cousins. The 13.3-inch A6 model starts at $699, while the 14-inch A10 model starts at $849.
