So, Grey = Tegra 3.5

Ahh by the time Tegra 4 devices ship the iPhone/iPad refresh will be right around the corner.

Sez who? Personally, I'm GUESSING Motorola might get that contract.

Doubtful that Motorola would get it considering they're working on the X-Phone and I doubt Google would want to piss off the other manufacturers.
Personally, I hope Sony gets it. It's their turn.

One thing I know for sure is that HTC isn't going to get it.

This looks like it will be great to power low cost 1080p phones and tablets. Something that the current tegra 3 struggles with on the resolution. It might be in the next kindle fire and nook HD lineup.

T4 and T4i are designed to compete against everything which comes out in the 2nd half of the year.

Tegra 3, when paired with DDR3L-1600, runs 1920x1200 pretty well. At least, on my TF700. Until you have to write more than 1/4th a MB to the internal storage.

As I've said before, what I'm most concerned about for a phone or tablet is battery life. At current speed levels, max performance comes second.


Sez who? Personally, I'm GUESSING Motorola might get that contract.

The contract has already been awarded. I read/saw few interviews with Google execs, the timelines and the inner workings were laid out as well. Most recent ones were with the exec responsible for supply chain and there was mention in the N4 video clip on the Verge site.

I'm hoping it's not LG again but the timeline coincides with the cryptic LG response ti the rumor of new N4 version. That's what I'm basing my assumption on, I could easily be wrong but I still think there is more logic in it than BGR's wild guesses.

If Google hadn't acquired Moto, they would be the most logical choice for N5 but there is a conflict of interest now. If the Nexus 5 is a high end Moto phone, regardless of price point, Samsung and HTC certainly won't be happy. Google must be confident that Android is too big to fail now and they have leverage to do things they wouldn't dare just a few years ago.

Even if someone else pocketed the Nexus contract this year, it's inevitable that Google will eventually switch to Moto. Nexus devices are to be free of carrier influences and free of OEM's restrictions as well. It's not only the carrier terms that piss Google off, I sense they are tired of meager productions, sibling units from OEM's and the resulting timing compromises.
Google needs the leverage, it needs full control of the Nexus devices and it's just a matter of time now. I still think they will keep the Nexus lineup discrete without carrier style marketing and I'm positive a Nexus device will never play second fiddle again to no Optimuses or RZR's. Ultimately OEM's will have to learn to launch around the Nexus, that lineup is about to stop compromising.

The problem with this reasoning is that there obviously *will* be a new N4 version: one for Sprint at the very least, and perhaps one for Verizon and/or a 32gb GSM one.

As for Moto, I think you have it backwards. Moto won't get the Nexus because Moto is now Google's vehicle to play ball with the carriers in a way that doesn't really jive with the Nexus line's real purpose. The X and its successors will be unskinned but not untampered -- which is how they'll sell millions and millions more than the Nexus.

With dual and likely single channel memory interfaces respectively, I don't see how that statement can hold true at all.

 

[djgandy]

I retract the above statement about T4i being single channel as after doing some analysis I don't think T4i is going to be 60mm2. I am not sure where Anand got that figure from in this article? http://www.anandtech.com/show/6753/...-4i-formerly-project-grey-with-integrated-lte

 

[Raghu]

Is it shipping 1Q2014 calendar year or NVIDIA financial year 1Q2014 (which is current quarter)?

 

[Mopetar]

Is it shipping 1Q2014 calendar year or NVIDIA financial year 1Q2014 (which is current quarter)?

Calendar year.

I don't think any company announces product ship dates based on their financial year, which is going to be different for every company.

The Tegra 4/4i die images in the link above are only a high level overview and are not a true depiction of the actual Tegra die. Tegra 4 (with 5 Cortex A15 CPU cores and 72 GPU "cores") reportedly has a die size area of ~ 80 mm^2. Tegra 4i (with 5 R4 Cortex A9 CPU cores, 60 GPU "cores", and integrated Icera i500 baseband processor) reportedly has a die size area of ~ 60 mm^2. Considering that the Cortex A15 CPU is approximately 2.35x larger in die size area compared to R4 Cortex A9 CPU, considering that a 72 "core" GPU is approximately 1.2x larger in die size area compared to a 60 "core" GPU, and considering that the Icera i500 modem is quite diminutive (whereas some other baseband processors are approximately 2.5x larger in die size area in comparison), the overall die size area quoted by Anandtech for Tegra 4i is certainly within the realm of possibility.

The conflict of interest is minor if Motorola is to do the Nexus once as part of a cycle of many manufacturers. And not as if Google is a government body anyway, so they can do what they please within reason.

Yes the contract has likely already been awarded, but I haven't seen any convincing info yet that it's not Motorola or that's it's LG.

Also, my carrier sells Nexus phones. It had the Galaxy Nexus and now it has Nexus 4. There's nothing stopping Google from doing the same thing with a Motorola Droid Nexus. In fact, people keep saying Google wants the Nexus to be this or that, but we've already seen that the Nexus is many things. Furthermore, we really don't know what X-Phone is. Is it the Nexus? Even if not, it's not as if Motorola is only capable of making one phone at a time. For all we know, the X-Phone is Motorola's flagship phone, but a different AOSP version of it will be the Droid Nexus, much like the the Optimus Pro vs. the Droid Nexus.

And finally, to give myself an out, if Motorola doesn't get the contract this year, maybe next year then.

Anand and Brian have their usual thorough breakdown of T4, T4i, and the baseband.

(1) Yeah, T4i is single-channel LPDDR3. Fine for phones, do not want in tablet/hybrid.
(2) It still has tons more shader power than T3 though, not sure how this isn't going to get memory bottlenecked. T4 proper is dual-channel, so no issue there.
(3) Don't understand the baseband stuff well enough to be sure, but it seems a pretty complete alternative to Qualcomm.
(4) LMAO at Phoenix having both on-screen buttons and capacitive ones...

This summarizes the Tegra 4 GPU architecture: http://pc.watch.impress.co.jp/img/pcw/docs/589/158/html/10.jpg.html , and this compares Tegra 4 to Tegra 3: http://pc.watch.impress.co.jp/img/pcw/docs/589/158/html/11.jpg.html. According to this slide, the Tegra 4 GPU clock operating frequency is 672MHz.

This summarizes the Tegra 4i GPU architecture: http://pc.watch.impress.co.jp/img/pcw/docs/589/158/html/16.jpg.html , and this compares Tegra 4i to Tegra 3: http://pc.watch.impress.co.jp/img/pcw/docs/589/158/html/17.jpg.html . According to this slide, the Tegra 4i GPU clock operating frequency is 660MHz.

So the Tegra 4i GPU architecture is significantly different than what most of us expected, with a very heavy focus on performance per mm^2 and performance per watt.

If I am reading NVIDIA's slides correctly, then Tegra 4i--intended for smartphones--will have 1.5x higher memory bandwidth than the Nexus 7 (due to use of higher frequency memory), while Tegra 4--intended for tablets and very high end smartphones--will have 2.3x higher memory bandwidth than the Transformer Pad Infinity (due to use of higher frequency memory and use of a dual channel memory controller).

Ahh by the time Tegra 4 devices ship the iPhone/iPad refresh will be right around the corner.

Yeah, but... so?

iPhone (and iPad mini R) will probably just use A6X shrunk to 28nm. iPad will probably go quad-Swift, with another predictable GPU boost.

So T4 will almost very likely win on CPU (A15>>Swift), which is no surprise, and lose on GPU, which is again no surprise.

So the die shots are just more Nvidia BS The T4i shot is just a photoshop job lol. Scale 75% and move some bits around.
