Previously codenamed “Wayne,” Tegra 4 is based around a quad-core ARM Cortex-A15 CPU with 72 custom Nvidia GeForce GPU cores, this means it has six times the GPU performance of Tegra 3.
Tegra 4 also supports 4G LTE voice and data comms with an optional chipset, the fifth-generation Nvidia Icera i500 processor.
“Tegra 4 provides enormous processing power and efficiency to power smartphones and tablets, gaming devices, auto systems and PCs,” said Phil Carmack, senior vice president of the Tegra business at Nvidia.
The chip has a Computational Photography Architecture, which automatically delivers high dynamic range (HDR) photos and video by fusing together the processing power of the GPU, CPU and the camera’s image-signal processor.
”Its new capabilities, particularly in the area of computational photography, will help improve a whole range of existing products and lead to the creation of exciting new ones,” said Carmack.
Tegra 4 consumes up to 45% less power than its predecessor, Tegra 3, in common use cases. And it enables up to 14 hours of HD video playback on phones.
