At the recent AsiaD conference, NVIDIA's CEO, Jen-Hsun Huang shared some thoughts about NVIDIA's mobile chipset roadmap. Apparently, they are developing all of their next "superheroes" all at once. Their roadmap starts, or course, with the "Kal-El" (Superman) chip that should make it out this year in the Asus Transformer Prime tablet. The next line of chips will be the Wayne (Batman), Logan (Wolverine), and Stark (Ironman). These chips are being concurrently designed to give NVIDIA a constant stream of chips to compete in the market.
Mr. Huang explained that it typically takes about 3 years of development to design a new generation of chip, and that the next line of chips will be the "Project Denver." The Denver chips will be an all new design and will debut right around the release of the Stark. The Denver Project is actually a joint venture between NVIDIA and ARM in which the two companies will create a custom combined GPU & CPU.
There is some additional news to go along with this report. Apparently, some industry insiders were able to dig up that NVIDIA's roadmap for their Denver project has slipped by about a year. There have been some technical hiccups that put them a bit behind, and the Denver project will end up being Tegra 6 sometime in 2013.
