NVIDIA Tegra Architecture

There's no reason to believe that Tegra K1-Denver will be ready before Cortex-A57 devices

Except for the fact that nVidia showed TK1 Denver running Android almost 5 months ago.

nor does it seem likely that Google would pick a chip without integrated LTE for a Nexus device.

So far there's been only two Nexus devices with integrated baseband (Nexus One and Nexus 5). Only one with integrated LTE (Nexus 5).
Nexus S, Galaxy Nexus, Nexus 4, Nexus 7, Nexus 7 2013, Nexus 10 and Nexus Q -> none of these bundled a SoC with integrated LTE.

Why would Google become so picky with LTE for their next Nexus devices, even more if we're talking about tablets?



Alexko said:
Hmm, it's Qualcomm, so I just assumed LTE was integrated, but now that you mention it, I don't know for sure. This page says the modem is a Qualcomm MDM9215M. Does that mean it's definitely discrete or could it be the name of the modem block in an SoC?

Snapdragon 600 doesn't have a built-in baseband processor. Snapdragon 800/801 does.


Alexko said:
I also wonder why Google would make such a choice. I guess it means they can use the same app SoC and PCB in all versions and just leave a few components out of the LTE-less one. But it makes the LTE version sub-optimal.

Still, Tegra K1 + discrete LTE modem seems like an expensive proposition for a Nexus device, certainly compared to the S600 in the current model.

LTE would be useless for a new Nexus Q (FireTV competition).

So? ARM and TSMC announced that A57 taped out on 16nm FinFET a year ago, and AMD's Seattle is sampling now, with launch scheduled for H2. If AMD can launch server-grade A57 SoCs this year, surely other companies can launch tablet chips around the same time or earlier.

Some S600 variants feature integrated LTE, some don't. http://www.qualcomm.com/snapdragon/processors/600 It sure didn't matter much when the Nexus S was released, but for a late 2014 device, that's a different story.

AFAIK, a core taped out != a SoC taped out, and nVidia has shown a TK1 Denver running Android.
AMD's roadmaps have been known to slip like a Curling champion, nonetheless.

I believe that's a typo in their page. I haven't heard of a single mobile device with the S600 that didn't have a discrete baseband processor.



You're under the crazy assumption that just because the Nexus 5 smartphone brought a SoC with LTE, all other Nexus devices from smartphones to tablets to set-top-boxes must also have a SoC with LTE.
 
For Android device makers looking to offer high-end 64-bitness as soon as possible, 64-bit Silvermont could be an option. While Samsung should be characteristically quick with availability of their A57 based SoC platforms, they haven't been too successful at selling to outside device makers as yet, and nVidia may just beat them to market with Denver... maybe. Qualcomm will be bringing up the rear in terms of availability with their A57 based hardware, but their complete platform solutions have tended to position them to dominate the product wins at most major device makers.

And if the hype driven demand for 64-bit devices doesn't substantially reach beyond the lower ends of the market where there's a glut of cheap, almost brand-less competing devices that have not-much-else outside of specs to distinguish themselves from one another, then A53 solutions from MediaTek, Allwinner, etc will capture most of the 64-bit opportunity and not let nVidia, Samsung or Intel really use this transition as a chance to better their position in the market.

If this has roughly the same battery life as the Shield-1 i might bite.
I will need those in spades now that a move to a low pop, limited electricity and bad internet area appears to be in my future.
The Anandtech Shield-1 review showed it having incredible wifi and HD movie playback duration.

Shield-1 uses a 7350mAh battery btw.

It is rumored to use a Snapdragon 800 so why have you posted this?

Your answer was just ONE CLICK away on the Kishonti link I provided: http://gfxbench.com/device.jsp?benchmark=gfx30&os=Android&api=gl&D=Lenovo+K1+HD+%282014%29&testgroup=info

http://users.otenet.gr/~ailuros/K1.jpg (for reference in case it disappears)

Take a long hard guess it's a DX11 GPU with OGL_ES3.1 drivers named GK20A. In fact just re-read my entire former post especially the last sentence.
 
Some good news on Tegra Automotive: Within the next few years, there will be ~ 30 million vehicles on the road with Tegra processors inside (today there are ~ 4.5 million vehicles on the road with Tegra processors inside). That is exponential growth for their automotive business! Even better is that ASP's should be significantly higher for Tegra Automotive-grade SoC solutions (ie. Tegra Automotive VCM) compared to Tegra Consumer-grade SoC solutions.

The 2016 Audi TT (available next year) will have a 12.3 inch TFT display powered by two Tegra K1 SoC's.

In addition to manufacturers who are currently on board, NVIDIA will be partnering with some big Japanese car companies (possibly Honda (?) who, along with Google, NVIDIA and others, is part of the Open Automotive Alliance) in the near future:

Bigger question what is the their margin on each SoC?, car companies are notorious for squeezing every last cent out of the supply chain.

Chip companies in general are pretty good at resisting the gross margin race to the bottom, especially the ones with high added value.
