Ontario, unlike Llano, will be fabricated at TSMC's 40nm Bulk process - the same over-capacity process shared by latest AMD and NVIDIA GPUs.
Ontario had been rumoured to be a 18W-25W product, but this has been doubted by sources close to AMD. Instead, Ontario is could be a sub-10W APU, as previously projected. However, there could be higher performance versions with higher TDPs.
In addition to netbooks, Ontario can scale down to other ultra-portable devices such as tablets.
Despite doubts over Ontario's demand by market analysts, Ontario's SoC nature, low power consumption, and performance reportedly nearly double of Intel's Atom, Ontario could prove to be a surprise success. Furthermore, the market for ultra-portable devices seems to be growing, alongwith a general increase forecasted for notebooks.
AMD's Llano is expected to power full-size notebooks, while Ontario is restricted to netbooks and ultra-thin notebooks.
