Personally, I expect that nVidia will align the GPU Technology Conference 2012 in San Francisco Bay Area with the official unveiling of Tesla boards based on Kepler, their next-gen 28nm architecture. If rumors are to believe, due to problems TSMC is experiencing with the 28nm process the initial 28nm silicon from AMD will be nothing more than a die-shrink of current 40nm GPUs (AMD Radeon HD 6000 Series). nVidia's 28nm Kepler though is expected to hit the stores as a consumer part in late 2011 and appear as a mission-critical part a few months afterwards. After all, as Teslas or Quadros, GPUs have no room for any silicon-related issues.
new Nvidia GPU late 2011?
