The Inquirer reports AMD will use 28nm for all of its GPUs and APUs in 2013:
AMD explained that it plans to move all of its chips over to a 28nm process node, though that won't happen until 2013. Currently only the firm's latest discrete GPGPU found in its Radeon HD 7950 and Radeon HD 7970 boards are fabbed at 28nm.
So it was no surprise that AMD said that its next generation Sea Islands GPU will also be fabbed at 28nm, but that it will be joined by Kavari, the successor to Trinity, which is expected to come out later this year. Kabini will straddle what the firm calls the low power APU - CPU and GPU on the same die - and its performance APU. Finally and perhaps the most interesting will be Temash, the firm's first generation system-on-chip (SoC), set to replace Hondo.
