TweakTown noticed some leaked details about NVIDIA's Tegra 4 (codenamed Wayne). This new SoC is anticipated to arrive in Q3 2013 and will be offered in four versions, all using NVIDIA's 4-PLUS-1 technology.
We have two "Flagship" models, the first of which should drop in Q1 2013 dubbed "T40" and will clock in at 1.8GHz and be made from the Cortex-A15 architecture, the second Flagship model is the "T43" and clocks in at 2GHz, this is from the same Cortex-A15 tech. We then have two "Mainstream" products that should arrive in Q3 2013.
These two models are "AP40" and "SP3X", with the latter coming in between 1.2-1.8GHz, and the former arriving in 1.2-2.0GHz. They will be based off of Cortex-A15 and Cortex-A9 designs for the AP40 and SP3X, respectively. One thing to note of the SP3X chip, is that it will finally bring with it LTE connectivity in the form of LTE100/HSPA42 tech, it will also be designed for 7-inch tablets, with the other three models made for 10-inch designs.
