Leaked Tegra 4 processor shows 4-plus-1 cores
The next generation of Tegra processors will be based on ARM's Cortex-A15 architecture, according to information leaked on a Chinese site this week.
Currently codenamed "Wayne," the new chip will be built using a power-efficient 28nm process and will eventually be renamed Tegra 4. The new processor will be built on Nvidia's 4-plus-1 technology, which consists of four regular cores and a special low-power core designed to help save battery life.
One surprise is the new chip's 72 graphics cores, which were highlighted in the leaked slide. That is six times as many graphics cores as found on the current-gen Tegra 3, said CNET. Together, the new configuration claims to offer six times the overall visual performance of existing devices.
Other specifications include support for USB 3.0, as well as a maximum screen resolution of 2560x1440. Tablets and smartphones powered by Tegra 4 are expected to arrive next year.
