TSMC has announced that its much awaited 28nm process is in volume production and the first production wafers has already been shipped to customers. TSMC currently offers 28nm tech in three forms - 28nm High Performance (28HP), 28nm High Performance Low Power (28HPL) and 28nm Low Power (28LP). 28nm High Performance Mobile Computer (28HPM) is due to be ready for production by the end of the year.
NVIDIA and AMD are both preparing next-gen GPUs on TSMCs 28nm, presumably 28HP and 28HPL. Due to cancelation of 32nm and delays for 28nm, 40nm has lived as the flagship process for GPUs an unprecedented over two and a half years. For NVIDIA, AMD and consumers alike, the volume production of 28nm will be a long built up sigh of relief.
AMD is rumoured to ship its first 28nm GPUs in December, with NVIDIA following in Q1 2012. However, the first 28nm GPUs are likely to be "pipe-cleaners", relatively small/mainstream GPUs to test the new process, with larger performance/enthusiast GPUs releasing later in 2012. AMD is also planning to source certain GPUs on its HD 7000 line from Globalfoundries 28nm bulk process later in 2012.
