They are not going to tell us ... some people who like the architecture will say it's because of the delays, some people who don't like it will say because it didn't perform up to snuff.Maybe it's my old age and/or ADD kicking in, but I'm missing the bit where this push-back has been acknowledged, purely or in significant part, to be down to h/w cache coherency and/or x86 "overhead". I wonder if there might be some quasi-religious projection going on in this thread ?!
As I said, I wonder if the developer kits will come with the rendering stack so we can judge the performance per mm2 proper ...
