According to Chinese site VR Zone, pictured above is a leaked roadmap of four upcoming iterations of the Tegra 4 processor from NVIDIA. I know, I know, we are just starting to see the first Tegra 3 devices and now are going to talk about what’s next? It’s tough not to when you see “4-PLUS-1” and “A15” on the same chart. That would mean the same quad-core architecture as their current T3 chipsets, but bumped up to cortex A15s over the A9s that most chipset manufacturers use today. We are talking monumental performance increases here.
We are also seeing LTE mentioned which is always a good sign, along with clock speeds ranging from 1.2-2.0GHz. The chart mentions 2013 for rollout.
While we always get excited about the future, we would love for NVIDIA to put out a Tegra 3 LTE device first, before worrying about the Tegra 4.
