Tegra 4 will reportedly feature a 72-core GPU.
A Chinese website posted what appears to be a legitimate slide of Nvidia's upcoming Tegra 4 architecture. Codenamed "Wayne," Tegra 4 will bring a 72-core GPU to the mobile fight, providing some powerful competition to Qualcomm's Snapdragon processors and Samsung's Exynos line. It will be built on a 28nm manufacturing process and sport the same "4-plus-1" core design featured in Tegra 3, which is basically a quad-core chip with a fifth battery saver core.
Tegra 4 will support resolutions up to 2560x1600, so it will have no trouble running "Retina Display"-like screens (to borrow a term from Apple). It will also support 1080p output at 120Hz.
According to the slide, performance will be 20X greater than Tegra 2 and 6X better than Tegra 3. It will support dual-channel DDR3L, LPDDR2, and LPDDR3 memory, as well as USB 3.0, which hints at the SuperSpeed USB port making an appearance on next generation smartphone and tablet devices.
