This year is a big one for smaller silicon manufacturing processes with Intel’s 22nm Ivy Bridge, and NVIDIA and AMD moving to 28nm GPU processes. According to a report on VR-Zone, NVIDIA is already planning their next move for Tegra, including a die shrink to 28nm.
They managed to get their hands on a road map (shown below) for NVIDIA’s Tegra SoC (system on a chip) lineup that extends into 2013. With Tegra 3, NVIDIA began by sampling the chip to Asus and the Transformer Prime. After that success, other partners and devices are starting to pick up the mobile chip, and they expect the situation to be the same for future Tegra iterations.
They company allegedly taped out a Tegra 4 (T40) SoC at the end of December 2011, and is starting to sample it to OEM partners to find someone to do a Tegra 3 like launch, with one device/platform to debut first and others to follow in later months.
The Tegra 4 chip is code named "Wayne" and will be comprised of multiple ARM Cortex A15 CPU cores and a new GPU on a 28nm process. The company alos plans to show off a dual core 28nm SoC that uses two Cortex A15 CPU cores, a revamped GPU, and an Icera 4G LTE radio at Mobile World Congress 2013 next year.
Further, the roadmap details a new Tegra 3 chip that is intended to be used with Windows on ARM powered notebooks and tablets. While the new Tegra 3 (T35) SoC will not be a die shrink, it will have higher clock speeds due to less restrictions placed on the maximum TDP (thermal design power) allowed for the devices. VR-Zone estimates that the T35 chips will run somewhere between 1.6 GHz and 1.7 GHz.
Currently there are some incompatibilities with Tegra and 4G LTE radios which has caused some LTE devices to go with Qualcomm SoCs, so it is good to see NVIDIA working on improving compatibility and then integrating the basebands into their future SoCs to rectify the issue.
As far as this year is concerned, we should see the updated Tegra 3 chip and a new version of Tegra 2 that integrates a Icera 4G LTE baseband. The Wayne and Grey chips will likely not be released until 2013 at the earliest. The expanded Tegra portfolio should help them to gain some market share, though exactly how much remains to be seen.
