What comes after Tegra 3? Tegra 4, it seems. Or ‘Wayne’. That’s the superhero-themed codename of Nvidia’s next-gen mobile chipset, and we see no reason for the company not to name it Tegra 4.
The first details about the Tegra 4 have been leaked via a slide that made its way to Chiphell, and the new chipset will probably get officially announced during CES in January or MWC in February.
The Tegra 4 will still come with a quad-core processor, and will keep the 4-PLUS-1 architecture of its predecessor. So in truth it will have five cores, four for performance, and one for low-power idling and performing tasks that aren’t resource intensive.
However, Nvidia will move to a 28 nm manufacturing process, matching key rival Qualcomm and its Snapdragon S4 chipsets. The Tegra 4 will be based on the ARM Cortex-A15 design, moving in the same direction as Samsung with its Exynos 5 processors.
The graphics part of the Tegra 4 will be the most exciting, with the GPU coming with no less than 72 cores. That’s exactly six times more than the Tegra 3, and this should apparently translate into a six-fold increase in graphics performance too (oh, and 20x better performance compared to the Tegra 2).
Those cores will be able to power screens up to 2,560×1,600 resolution, complete with 1080p video output at 120 Hz.
Dual-channel DDR3L memory will be supported, as will the USB 3.0 spec, and even hardware accelerated security features.
