Nvdia and Intel both cracked under AMD pressure
In their effort to catch up with AMD, both Nvidia and Intel seem have suffered from capricious and imprudent execution. Nvidia's 28nm GPU is getting pitiful yields. Intel had to fake DX11 at CES and now it is reported that Ivy Bridge is a bridge too far -- it is being postponed to after June 2012.
Meanwhile, Trinity is shipping and there is apparently no shortage of 7000 GPUs.
