The Register had a chance to sit down with Steve Scott, once CTO of Cray and now CTO of NVIDIA's Tesla projects to discuss the future of their add-in cards as well as that of x86 in the server room.  They discussed Tegra and why it is not receiving the same amount of attention at NVIDIA as Tegra is, as well as some of the fundamental differences in the chips both currently and going forward.  NVIDIA plans to unite GPU and CPU onto both families of chips, likely with a custom interface as opposed to placing them on the same die, though both will continue to be designed for very different functions.  A lot of the article focuses on Tegra, its memory bandwidth and most importantly its networking capabilities as it seems NVIDIA is focused on the server room and providing hundreds or thousands of interconnected Tegra processors to compete directly with x86 offerings.  Read on for the full interview.

"Jen-Hsun Huang, co-founder and CEO of Nvidia has been perfectly honest about the fact that the graphics chip maker didn't intend to get into the supercomputing business. Rather, it was founded by a bunch of gamers who wanted better graphics cards to play 3D games. Fast forward two decades, though, and the Nvidia Tesla GPU coprocessor and the CUDA programming environment have taken the supercomputer world by storm."
