Earlier this year, NVIDIA showed off a roadmap for its Tegra line of mobile system on a chip (SoC) processors. Namely, the next generation Tegra 4 mobile chip is codenamed Wayne and will be the successor to the Tegra 3.
Tegra 4 will use a 28nm manufacturing process and feature improvements to the CPU, GPU, and IO components. Thanks to a leaked slide that appeared on Chip Hell, we now have more details on Tegra 4.
The 28nm Tegra 4 SoC will keep the same 4+1 CPU design* as the Tegra 3, but it will use ARM Cortex A15 CPU cores instead of the Cortex A9 cores used in the current generation chips. NVIDIA is also improving the GPU portion, and Tegra 4 will reportedly feature a 72 core GPU based on a new architecture. Unfortunately, we do not have specifics on how that GPU is set up architecturally, but the leaked slide indicates that the GPU will be as much as 6x faster than NVIDIA’s own Tegra 3. It will allegedly be fast enough to power displays with resolutions from 1080p @ 120Hz to 4K (refresh rate unknown). Don’t expect to drive games at native 4K resolution, however it should run a tablet OS fine. Interestingly, NVIDIA has included hardware to hardware accelerate VP8 and H.264 video at up to 2560x1440 resolutions.
Additionally, Tegra 4 will feature support for dual channel DDR3L memory, USB 3.0 and hardware accelerated secuity options including HDCP, Secure Boot, and DRM which may make Tegra 4 an attractive option for Windows RT tablets.
The leaked slide has revealed several interesting details on Tegra 4, but it has also raised some questions on the nitty-gritty details. Also, there is no mention of the dual core variant of Tegra 4 – codenamed Grey – that is said to include an integrated Icera 4G LTE cellular modem. Here’s hoping more details surface at CES next month!
* NVIDIA's name for a CPU that features four ARM CPU cores and one lower power ARM companion core.

In the middle of 2011, NVIDIA acquired a small company by the name of Icera, a maker of baseband and RF technologies that would eventually allow the company to integrate the two into a single chip. As LTE-capable devices from Verizon, AT&T and even Sprint have been announced and ship, no NVIDIA Tegra-powered phone or tablet has been able to support the feature with the lone exception of the ZTE Mimosa X in February of this year.
Today NVIDIA officially announced support and validation from AT&T on their new and growing LTE network for the Icera 410 LTE multimode chipset. This will finally allow Tegra + LTE devices to be sold and available in the US and other markets when product manufacturers integrate the two processors in future designs.
As to when we will see those designs, we aren't quite sure but nothing was announced during the NVIDIA investors day today. All we know now is that they will be coming "through this year and next."
“Validation with AT&T is an achievement that paves the way for NVIDIA Icera-powered LTE devices on the AT&T network through this year and next,” said Stan Boland, senior vice president of Mobile Communications at NVIDIA.
The NVIDIA Icera 410 LTE modem delivers lightning-fast web browsing, video streaming and multiplayer gaming to tablets and clamshell devices. It is the first Icera modem to implement 4G LTE in NVIDIA’s software defined radio baseband processor. Together with its multimode radio transceiver, the chipset offers 4G LTE at category 2 data rates (up to 50 Mbps) as well as 4G HSPA+, 3G and 2G compatibility.
What we DID learn at the NVIDIA investors meeting is that Mike Rayfield, GM of Tegra business unit, things we'll see as many as 30 Tegra 3 based devices for sale this year.
NVIDIA has 30 devices planned for the year. So far, we've seen just two. Of those 30 devices, some 15 will be planned for sub-$200 pricing. That's certainly the sweet spot for impulse purchases.
NVIDIA's also looking to make inroads into the Chinese market, with 18 of those 30 tablets targeted for the Asian nation. By comparison, NVIDIA only released five devices in China in 2011, Rayfield said.
The big name to know for the rest of the year is Kai. That's the low-cost, high-performance system that NVIDIA is crowing about these days, and it's what will help bring prices down while keeping prices at a more affordable level. Will there be higher-performing tablets? Sure. But will they be $200?
Producing a number of devices, like 30, is impressive but without context the fact means very little. How many of these devices are going to tablets and how many are phones? How many will be running the Microsoft Win RT operating system for ARM due out in fall?
Speaking of Icera though, NVIDIA also showed the roadmap for LTE integration including the upcoming Icera i500 LTE controller for high-end phones and tablets with newly planned integration directly on the Tegra core in a new chip called "Grey". This new processor will run parallel with the planned 2013 release of "Wayne" though it will be targeted at smartphones and lower end tablets; Wayne is planned to find its way into higher end tablets and the onslaught of clamshells we'll see with Windows RT.
There is a lot more to learn and we expect see more news come our way as we approach Computex in Taipei!

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.
