[Asus  Eee Pad Transformer Prime] demandarin:
For all things Tegra4.

Early reports from MWC confirmed first Tegra4 chips-Multicore 28nm A15 Cortex chips(I think it may have 8 cores) have been stamped in December and already in hands of OEM for testing and use. With all the hot competition going on now, Nvidia is speeding up the process to bring these to market ASAP. with chips like Qualcomm S4, apple new chip, and Samsung Exynos, Nvidia is coming with all guns blazing to stay ahead of everyone. A version of Tegra4 codename Grey will eventually be released with built in LTE radio. this came from the assimilation of Icera. ill even admit, with tegra3 not currently having an LTE or built in radio, it might be overlooked by some companies if they want to make a data connection model. not all companies make those tablets so Tegra3 will still have a very large footprint of tablet devices as already seen from what's been announced at MWC and before. at least 11 devices so far will use the tegra3 chip.

with the competition getting fierce Nvidia is looking to stand strong behind the Tegra brand. So be on the look out in this thread for latest Tegra4/Wayne/Grey info and specs.

I will update this OP with Tegra4 news and specs. can't wait to see how much more powerful this puppy is than what's currently out or coming out.

until OP is updated with more Tegra4 news, here is a very good read for all you tech heads. Huge breakthroughs are about to be reached in CPU scaling and mobile computing.

FUTURE OF CPU SCALING: EXPLORING OPTIONS ON THE CUTTING EDGE

www.extremetech.com/extreme/120353-the-future-of-cpu-scaling-exploring-options-on-the-cutting-edge

More info: around October 2012 release @ earliest for Wayne/second most powerful version

1)Confirmation first version of Tegra4 will be 28nm Quad core A15 Cortex CPU @ 1.5Ghz and will have a 24 Core high powered GPU

2)SECOND version of tegra4 will be alot more powerful than the first. It will have no less than a 8 core CPU and have between a 32-64 Core GPU which will be DirectX compliant and more high standards. Look at screenshots for details

UPDATE 3/30/2012: Tegra4 will more than likely be Keplar based. All indications point to it.

Some details and facts on the matter:

-" Nvidia’s Tegra 4, codenamed Wayne, included assertions that Nvidia’s next-gen SoC will use a Kepler-derived graphics core. That’s probably true, but the implications are considerably wider than a simple boost to the chip’s graphics performance. Tegra 4, also known as T40, could very well be a fundamental game-changer for Nvidia and the most important Tegra product to date"

-Improved Game Performance:

" The GPU that powers Tegra 2 and Tegra 3 has a fixed number of pixel and vertex shaders and is much more closely related to GeForce 7-era products than the Unified Shader Architecture Nvidia debuted with the G80 (GeForce 8). When Nvidia describes T2 & 3 as “fully programmable,” it’s true — but it’s not at all the same as being DirectCompute/CUDA/OpenCL-compatible. Current Tegra products are capable of running complex shader programs, but not the general-purpose code that makes things like PhysX or GPGPU calculations possible"

Unifying of Shader Architecture

-" GPUs with a Unified Shader Architecture (all Nvidia products from G80 onwards) have two advantages over their fixed-function cousins. First, they’re more efficient. A fixed-function GPU’s performance can vary considerably from game to game depending on whether a title emphasizes pixel shading or model geometry; this is quite visible when comparing performance between Tegra 2/3 and the SGX 544. A Kepler-based GPU would be much more flexible, able to allocate its execution resources to process either workload. This can indirectly lead to decreased power usage — a wide array of more efficient stream processors doesn’t necessarily need to run at nearly as high a clockspeed as a fixed-function chip.

Second, and arguably more important, is their ability to handle functions that would normally be processed on the CPU. This is where we expect T40 to come into its own."

-" As a software SDK for physics calculation, Nvidia’s PhysX solution has been quite successful; it’s used in nearly 400 games across consoles and PCs"

Tegra4 Goes Beyond Gaming

-" Tegra 4 also gives Nvidia a fresh platform with which to bundle its Icera modem and DirectTouch products. Its Icera product family is a set of softmodems for LTE and WiFi, while DirectTouch is technology that “improves touch responsiveness by offloading some of the touch processing that is typically performed by touch controllers and touch modules onto the Nvidia Tegra 3 application processor [Companion Core]. The architecture also simplifies the implementation of touch based hardware and user interfaces, requiring less power while delivering more scalable performance.”

Speaking of the Companion Core, Tegra 4 will almost certainly include an enhanced version of the architecture. With Tegra 3, Nvidia chose to build an array of five Cortex-A9 cores — in Tegra 4, the company could opt to adopt the sort of hybrid strategy ARM introduced with big.LITTLE (Cortex-A15 cores for heavy lifting with a Cortex-A7 chip for low power) or use a hybrid A9/A15 arrangement"

-" A Kepler-based GPU will also likely improve Tegra 4′s video encode/decode capabilities as compared to Tegra 3. This is one area where the T2/T3 family is significantly more advanced than the GeForce 7-era hardware they resemble in other respects, but a GK104-derived chip could improve the situation further by either increasing power efficiency, supporting a wider variety of formats and standards, or providing an increased number of post-processing options"

-" Nvidia has always marketed CUDA as a capability that could exponentially increase performance, but the company’s efforts in this area have mostly been confined to scientific computing or high-end industrial applications" Opportunity for CUDA is in Tegra4

VERY IMPORTANT RIGHT HERE!

-" Nvidia can’t count on the Cortex-A15 as a differentiator, given that the likes of Samsung and Texas Instruments will have their own A15-based products out by the end of the year as well. Graphics are the logical area for Nvidia to emphasize; a mobile GPU based on Kepler would be far more advanced than anything currently offered by Imagination Technologies’ PowerVR, ARM’s Mali, or the aging Adreno core."

-" We expect the company will attempt to position Tegra 4 as a chip that can leverage its GPU in ways that are beyond its competition. If the hardware delivers and the software support is in place, it could give Nvidia a potent weapon against OMAP5, Exynos, and future Medfield products from Intel."
