NVIDIA's next superhero-themed mobile chipset has possibly made an early appearance in a leaked side in China, and it looks like it wants to go toe-to-toe with the latest processors from Samsung and Qualcomm. The Tegra 4 (codenamed Wayne) will apparently offer the same power-efficient 28nm process found on its Snapdragon rival and according to the slide from Chip Hell, there's a dizzying 72-core graphics setup. That's six times as many GPU cores as Tegra 3 -- the processor found in the Nexus 7, for example -- and the increase is claimed to result in six times the overall visual performance. Those graphics cores will be able to feed displays of up to 2,560 x 1600, with 1080p output at 120Hz, while the leak also mentions 4K -- if only in passing. There's no increase in CPU cores this time, with the same 4-plus-1 setup , but we are seeing its move to ARM's latest design, the Cortex-A15. Tegra 4 will apparently also catch up with USB 3.0, being NVIDIA's first mobile chip to do so, alongside dual-channel DDR3L memory. We've reached out to chipmaker and we'll let you know when we hear more, but it's highly likely we'll be welcoming this next-generation processor early next year -- say, at a certain mobile trade show.
