It appears that first specs about Nvidia's "Wayne" Tegra chip, the successor of Kal-El (Tegra 3) have been leaked.
Slated for a Q1 2013 release, the processor will arrive with four 28 nm ARM A15 cores and a clock speed of 1.8 GHz on the high-end for 10-inch tablet and notebook devices. A 2 GHz and a 1.2 GHz - 1.8 GHz version will follow in Q3, while there will also be an ARM A9 version with 1.2 to 2.0 GHz that will feature the Icera LTE100 / HSPA42 baseband chip and will be made available for 7-inch devices.
Tegra 4 was originally promised to arrive this year, but has been delayed to 2013. Market rumors suggest that the delay of Wayne could be due to Nvidia's decision to build Kepler GPU technology into these devices. The chip is promised to deliver about 10 times the performance of Tegra 2 on the high-end - and twice the performance of Tegra 3. With at least four different version on tap, Nvidia is aggressively broadening the market reach of Tegra.
