*** OFFICIAL - CES 2013 Thread***

Yes, a pointless marketing gimmick. They should turn off the other 3 cores like Qualcomm/Samsung or use a proper low power core like ARM.
Shame it uses old GPU architecture too, where's the unified design Nvidia? Logan or Grey?
Oh and Sony already has HDR covered with 'on sensor' processing for 30/60fps not 4! :p (far more efficient too)

Tegra 4 isn't suitable for phones btw, check out that huge heat sink on the Shield controller! :D

4 x A15's in a phone is such an overkill! Tablet - most likely ok but big.little would be better.

Have they finally got fast dual channel memory? Don't tell me it's still single :D
 
Just read from Anandtech:

I swear Tegra 3's 'companion core' made f-all difference. I think this will be the same too.

I'm not sure I like the idea of having the battery saving core as an A15 as well... especially considering how power hungry and hot the Tegra 3 was. And the dual A15s in my Nexus 10 gets pretty warm under load as well... I really am not liking the sound of Tegra 4 so far :p.
 
Yeah this thread was just meant for tablets, phones.

Talk about TV's and media players if you want - not much else going on right now :)
 
I really like Tegra 3- I found it supported flash better than what was in my GS2 and GS3. Bizarre but true.
 
Can't be as all the literature says 4 A15 cores though I can't find any information stating what 'second-generation battery saver core' it is. Though this suggests it is a A7 like you said.



It is using big.LITTLE right?

It's not big.LITTLE, not least because it appears (although unconfirmed?) that it's another A15. big.LITTLE, in the true sense of a software control over what core is being used, is a fair way off, the Linux scheduler doesn't currently have much support for it except some theoretical bits, but it is obviously on the to-do list, needs some hardware for it to really work though.

The companion core, like I said in the ancient Tegra 3 thread, is a crappy bodge to get around their lack of proper core-specific power/clock controls, instead all 4 cores run at once, it's a bodge that only really effects idle usage as well.

Shame TI never got around/haven't yet got around to bringing out the design that was dual-core A9's and dual-core M3's with the idea that the tiny M3's could do some of the kernel load etc (at least afaik it's not been released/used yet...)

Also Anandtech did some interesting power consumption stuff on the Nexus 10 the other day, that thing draws some serious current for a mobile device, gonna be interesting how Samsung handle that in a smartphone (presumably SGS4 will be A15 based...)
 
A big massive bodge - all you need is full power gating (switching off cores when not needed) like you get in Exynos and Krait.
 
So you want a backup phone:

SpareOne, Honored as Best of Innovations at CES 2013 for Being the Only Mobile Phone Powered by a Single AA Battery, Debuts SpareOnePlus at the Show

SpareOne, designed to be an ultimate safety and communication device, provides up to 15 years of battery life when stored unused (off, with plastic tab inserted) or 10 hours of talk time when in use. Features include a TorchLight on top which provides 24 hours of continuous light; a dedicated 911 dial button to alert authorities, which works with or without a SIM card; ability to pre-set 9 speed dial numbers; and a new talk-through, re-sealable waterproof bag with a humidity-proof seal. The floatable bags operate in extreme temperatures of -22F to 140F and protect against water submersion for 30 minutes at a depth of 1 meter, also designed with room to accommodate a few small items such as credit cards, bandages, etc.

They have! All OMAP 4s have two Cortex-M3 processors for sub system processing. TI make the best low power chips the only problem is old 3D GPUs, execution speed and crappy marketing. AMD should buy the OMAP division asap tbh.
 
I stand corrected, for some reason I thought TI had a planned OMAP4 based chip that had 2 'general purpose' M3 cores that could/would be used as a big.LITTLE type system, but that appears to have never been the case.

TI didn't pull out of the SoC market (they sell way too many of them for that), but they pulled out of the smartphone/tablet market effectively, essentially I think the rate of development was too expensive for them and they make plenty of money from other DSP based SoC's (lots of video encoder/decoder style stuffs), I'm sure they'll re-enter the market sooner or later but might as well wait for the progress to slow down a bit. I guess also without making devices themselves the margins are probably too low, get a dollar or two for the SoC or $100+ for a phone...
 
Well Tegra 4 looks to be what everyone expected. A good CPU coupled with an outdated GPU. Assuming the early x3 to x4 speed over Tegra 3 numbers are true.

EDIT: Worse then I thought. The shaders aren't unified yet! What happened to updateing to modern technology?

Not much of interest I could see from today.
Asus google cube tv
And qaulcoms next mobile CPUs 800 & 600, got feeling terra 4 will be behind again, but who knows.
They say 800 is 75% faster than the s4 pro, that's a hell of a chip. And signs intel failure with the atom. Although I hope haswell will be different.
