What will eventually be known as Tegra 4 is currently known as Wayne, an internal name for Nvidia’s next-generation ARM-based system-on-a-chip.
Made with a thermally-efficient 28nm manufacturing process, dual-channel DD3 memory, support for 2560×1600 displays, USB 3.0 and more, the system is decidedly next-generation. More importantly, while the CPU portion will be incrementally faster than its current variant — still quad-core with a low-powered battery-saving fifth core — it’s the 72-core graphics processing unit that we’re truly excited about. Promising six times the computational potential of its Tegra 3 predecessor and an amazing 20x improvement over the Tegra 2, Wayne promises to be a gamer’s dream chip.
Unfortunately it looks like Nvidia still hasn’t managed to integrate a LTE baseband on to the powerful SoC. What this means is higher power consumption for anyone looking to integrate the processor with high-speed networks like we have in North America. It’s likely that there is no room left on the chip itself after you take into account all the I/O, so Nvidia made the decision to leave out LTE until next generation. That chip, codenamed Grey (get the trend here), will be debuting in late 2013 or early 2014, according to sources.
