nVidia Wins With Tegra 4
Nvidia’s first Tegra 4 design win is here, apparently, and it doesn’t appear very impressive at all. Tegra 4 is late to the party, so it is a bit short on design wins, to put it mildly.
Now a new ZTE smartphone has been spotted by Chinese bloggers and it seems to be based on Nvidia’s first A15 chip. The ZTE 988 is a phablet, with a 5.7-inch 720p screen. It has 2GB of RAM, a 13-megapixel camera and a 6.9mm thin body. It weighs just 110g, which is pretty surprising. The spec is rather underwhelming, especially in the display department.
However, a grain of salt is advised. It is still unclear whether the phone features a Tegra 4 or a Qualcomm chipset. Also, it is rather baffling to see a 720p screen on a Tegra 4 phablet, it just seems like overkill.
Are CUDA Applications Limited?
Acceleware said at Nvidia’s GPU Technology Conference (GTC) today that most algorithms that run on GPGPUs are bound by GPU memory size.
Acceleware is partly funded by Nvidia to provide developer training for CUDA to help sell the language to those that are used to traditional C and C++ programming. The firm said that most CUDA algorithms are now limited by GPU local memory size rather than GPU computational performance.
Both AMD and Nvidia provide general purpose GPU (GPGPU) accelerator parts that provide significantly faster computational processing than traditional CPUs, however they have only between 6GB and 8GB of local memory that constrains the size of the dataset the GPU can process. While developers can push more data from system main memory, the latency cost negates the raw performance benefit of the GPU.
Kelly Goss, training program manager at Acceleware, said that “most algorithms are memory bound rather than GPU bound” and “maximising memory usage is key” to optimising GPGPU performance.
She further said that developers need to understand and take advantage of the memory hierarchy of Nvidia’s Kepler GPU and look at ways of reducing the number of memory accesses for every line of GPU computing.
The point Goss was making is that GPU computing is relatively cheap in terms of clock cycles relative to the time it takes to fetch data from local memory, let alone loading GPU memory from system main memory.
Goss, talking to a room full of developers, proceeded to outline some of the performance characteristics of the memory hierarchy in Nvidia’s Kepler GPU architecture, showing the level of detail that CUDA programmers need to pay attention to if they want to extract the full performance potential from Nvidia’s GPGPU computing architecture.
Given Goss’s observation that algorithms running on Nvidia’s GPGPUs are often constrained by local memory size rather than by the GPU itself, the firm might want to look at simplifying the tiers of memory involved and increasing the amount of GPU local memory so that CUDA software developers can process larger datasets.
Will Tegra 4 Help nVidia’s Financials?
Comments Off on Will Tegra 4 Help nVidia’s Financials?
Trefis analysts believe Nvidia’s Tegra business is likely to grow over the next few years, although Nvidia won’t become a mobile chip company anytime soon.
In a note published a couple of days ago, Trefis concluded that Nvidia has managed to offset the impact of the PC slump thanks to mobile revenue. The PC market took a massive hit in 2012, and although things are looking up, Tegra could still come in handy.
Nvidia currently earns about 18 percent of its revenue from Tegra processors, which is not bad for a product that was on the drawing board just a few years ago.
“We estimate Tegra sales to grow at a CAGR of 17% until 2016. While we believe that Nvidia will manage to expand its footprint in mobile computing, we think that the increasing competition will keep its growth rate lower than the industry average,” said Trefis.
However, Trefis went on to conclude that Nvidia had more lack with tablets than smartphones. Last year it scored several big tablet design wins, but relatively few phone wins. The Tegra 4i, with integrated LTE, should lend a helping hand, but it won’t be ready for much of 2013. In addition, Nvidia is facing more pressure from Qualcomm and Samsung, while at the same time it was forced to push back the introduction of Tegra 4 due to technical issues.
Trefis believes Tegra’s contribution to Nvidia’s overall revenue could reach over 25 percent by 2019, which means the Tegra business won’t expand much in a mature smartphone market.
Nvidia has Tegra, AMD has consoles, so both outfits have something to fall back on in a slow PC market, at least for the time being.
Will Tegra 4 Launch In Q2?
Tegra 4 was supposed to be production ready in Q4 2012 and the general expectation was that CES 2013 would be marked by the launch of phones and tablets based on the new chipset.
It turns out that the chip needed another re-spin, something that usually creates a delay of roughly a quarter. We don’t know which part of the chip was to blame but our sources claim that Tegra 4 is a complex chip with a lot of components where many things can go wrong.
Nvidia dared to move to 28nm, change the core from A9 to A15 and find a way to make its LTE work. There were a lot of things that could go wrong and obviously some did.
This is why Intel first shrinks the core, for example from 32nm to 22nm, and then in its “tock” cycle goes for a newly designed core. Nvidia doesn’t have that luxury, as making a 28nm version of Tegra 3 would not be enough for the SoC market in 2013.
A few people at Nvidia have been telling us that the chip has been sampled to accounts and Nvidia is planning to have some designs announced at the Mobile World Congress. We managed to confirm this schedule with some Nvidia partners.
Will Tegra 4 Support USB 3.0?
Wayne, also known as Tegra 4 is coming out at CES 2013, or in some 10 days from now. Nvidia has an event planned days ahead of CES 2013 and the company will likely show some tablets and hybrids based on the new Tegra SoC. Let’s call Wayne Tegra 4 before it gets official.
Nvidia had Wayne ready to launch in Q4 2012 but it had to wait for partners to release the designs based on it, and most of them wanted to do it at CES 2013. European phones based on Wayne are going to show up in February, at the Mobile World Congress.
This is the first quad-core A15 design that will bring a significant performance increase over Tegra 3 and we are hearing that the four-plus-one core will deliver a bigger performance boost than Tegra 3 did over Tegra 2. Also, the fact that the new chip is 28nm and supports DDR3L also promises more efficiency.
USB 3.0 support is something that is getting us excited as usually it is quite slow to transfer anything onto tablets, phones and hybrids. USB 3.0 on tablets will significantly increase the data transfer speed and Tegra 4 will be among the first chips to feature USB 3.0 support, and many consumers will appreciate faster data transfer rates.
The other thing that got our attention is dual display support and you will be able to have two independent screens. On Tegra 3 based devices, you can only mirror the output, not display two independent screens. It could be a very interesting feature for dockable devices.
nVidia’s Tegra 4 Specs Spotted
Here is an interesting leak, just what the doctor ordered to spice up a rather slow news cycle. Chiphell has posted a slide containing a few Tegra 4 specs, but we still don’t know the clocks or a few other interesting details. Of course, the leak should be taken with a grain of salt, but the specs are more or less in line with what we were expecting all along.
Tegra 4, codenamed Wayne, is a 28nm part with revamped graphics and new ARM cores. Although the slide does not directly point to the type of ARM cores used in the design, the new chip is based on ARM’s latest A15 core. Like the Tegra 3, the new chip will also feature an additional companion core to improve energy efficiency. No surprises here really.
In terms of GPU performance, Nvidia promises to deliver a six-fold improvement over the Tegra 3 and a 20x improvement over Tegra 2 chips. Oddly enough, in spite of Nvidia’s graphics prowess, Tegra chips never featured world-beating graphics. This time around they could, thanks to the new 72-core GPU. The GPU will be able to cope with 2560×1600 screens at 120Hz, but it could also take on 4K resolutions, although details are still sketchy. At this point 4K support could only be relevant for next-generation smart TVs, with a huge price tag.
As far as other features go, Tegra 4 brings support for USB 3.0 and DDR3L dual-channel memory. The leak does not mention LTE support.
Tegra 4 will have to take on the likes of Samsung’s upcoming Exynos 5440, which should also debut in early 2013. Nvidia was first to market with a quad-core A9 chip, but this time around it will have to face off against the new Exynos and A15 quad-cores from other vendors.
Nvidia is expected to showcase the new chip at CES and we’ll be there to check it out.
nVidia Soars
Nvidia has published its third quarter earnings and the results are impressive to say the least. With record revenue of $1.2 billion, Nvidia’s net income in Q3 was $209.1 million (GAAP).
Quarterly revenue is up 12.9 percent year-over-year and represents a 15.3 percent sequential bump, beating analyst expectations. However, Nvidia expects its revenue to dip to between $1.02 and $1.17 billion in the fourth quarter.
The company blames the projected slump on a declining PC market. It seems Nvidia does not expect Windows 8 will have a very positive impact on the PC market.

Comments Off on Cars May Come With nVidia’s Tegra
One of the things that we keep hearing as a big business opportunity for ARM manufacturers is to get their chips in cars. We heard this before, but this time we are not talking about navigation / entertainment systems.
The idea behind the concept is that more and more cars will come with collision detection mechanisms, road tracking that can keep your car stay in the high way lane. It gets better, the car can now lock on the car in front of you and accelerate and decelerate with it, so called adaptive cruise control with some manufacturers.
Fancier cars today come with elaborate stability assistance systems and many other features that might put such processors to good use, for something far more useful than just navigation and playing music.
Most Tegra 2 Tablets Will Get ICS
Sources have confirmed that most Tegra 2 tablets you know will get Ice Cream Sandwich. We are still sniffing around to find out if the ICS is going to end up as Android 4.0 but it will bring phones and tablets much closer and should ship in October or November.
Many Asus, Samsung, Toshiba, Lenovo, Sony and any other Android 3.x compatible tablets on market will have a chance to get the new one. The upgrade will come as manufacturers get it ready and customized for its tablets but most tablets will ship with Android 4.0, Ice Cream Sandwich, probably early next year at the latest.
This is good news for many who were brave to buy the first generation of tablets not based on Apple’s architecture and it will help Google to gather even more momentum for 2012. 2012 looks like a year when Google will be ready for real war against Apple, but at the same time, Android supporters fear that Windows 8 will get a lot of attention when it ships in late 2012.

Comments Off on nVidia’s Tegra 3 Coming To Smartphones
It appears as though Nvidia’s next generation quad-core Kal-El (Tegra 3) quad core SoC will also show up on smartphones too. Originally, it was believed that the SoC would only support the ever growing tablet space.
Inside sources have confirmed that projects are already underway and that Tegra 3 aka Kal-El smartphones will be make a debut as well.
Nvidia had hoped to get a lot of play out of Tegra 2, unfortunately the chip was not as embraced as Nvidia had wanted. Even though the Tegra 2 SoC did manage to get a few design wins.
