but isn't tegra slower than their competitors? it is fun that they spent money on a 150 mbps modem, when in my country you cant get more than 1,5mbps on a wired connection, and dont get me started on how painfully slow is the cellphone internet

Quad-core Cortex A15 has some serious performance enhancement implications. It'll take more detailed specs before I'd make any more exact estimations on where it stands, but the implications are good thus far.

I'll believe 'great battery life' when I see it. The ZTE devices always have low MAH, and they also seem to get less runtime per MAH than higher cost devices.

how is it their Tegra business is dying? just because the rumor nvidia having trouble convincing phone/tablet maker to use their Tegra 4 then the division suddenly dead. also those Tegra chip are not limited to phone and Tablet as well.

[citation][nom]blazorthon[/nom]How is Cortex A15 outdated?[/citation]
The A15 design was finished in 2011, it went into devices in 2012. It's 2013 and Nvidia is only just now announcing that Tegra4 will be out in devices, but not until Q3 of 2013. I'd say that's pretty outdated. The S4 pro Krait is already in many products, and generally rivals the A15 architecture in overall performance.

A15 is still ARM's fastest arch IIRC and it wasn't used much until a few months ago at the most from what I've read. It isn't outdated unless you call being the most recent ARM architecture outdated. Also, if Krait is currently only matching A15, then it certainly doesn't help you prove your point. Sorry, but I don't understand your reasoning.

OK, here's the logic. Tegra 4 is based on A15. Tegra 3 is based on A9. A15 is ~40% faster than A9 clock-for-clock, so we know tegra 4 is going to be faster than 3, assume 40% (cpu-wise). But the current S4 pro/Krait is already as fast as A15-based systems. It was shown already that Tegra 4 won't be clocked much different than 3 (1.9ghz vs. 1.6ghz max). That's great except the currently-available Krait is already as fast as A15-based systems. Ergo, the current competitor's chips are already as fast as tegra 4, except T4 won't launch in products until 6 months from now. Qualcomm has already announced their successors to the S4 pro (nomenclature changes aside), which they claim to continue their performance improvements over the previous generation (we can take that with a grain of salt; every manufacturer likes to say this about next-gen releases).

However you break it down, Tegra 4 will be using an outdated cpu platform when it goes live. That's not to say that their claims of "six times the graphical capabilities" of Tegra 3 can't be useful, but it's a sad fact of the matter that for being released into the wild six months from now, T4 won't be using a very current cpu platform. It'll only be catching up to what is already available right now.

OK, I get it now.

i don't follow much about this SoC business. so what is the latest architecture from ARM right now? (that being use in current device)

The latest commercially-used instruction set for ARM-based processors is typically ARMv7, and is generally an old (but not necessarily bad) instruction set that's been used for quite some time; but that's not the only part of the architecture. The architecture varies from platform to platform. Snapdragon-based ARM platforms had a lot more components integrated onto them with development (GPU/cellular/GPS/wifi/bluetooth) vs. using a separate PCB for these components. But most other platforms have begun to integrate these things recently as well.

I'll admit to not knowing exactly what about Qualcomm's or Tegra's platforms makes them better or worse in various areas compared to other ARM-based CPU platforms; only that most mobile-based processor designers have made extensive efforts to integrate most components onto the chip--making them system-on-chips.

I think it's all really interesting where the industry was going. I was probably a bit too harsh in my analysis of Tegra 4, but the fact still remains, their release cycle seems to lag quite a bit behind the competitors in the mobile arena.

Rather than repeat myself:
http://www.tomshardware.com/reviews/tegra-4-tegra-4i-gpu-architecture,3445.html
See my comments to blazorthon. S600 already losing to a dual core A15, anand benched an S600 at MWC last week, it lost. Note you can't actually buy it yet (unless I missed a release date...LOL), so it's not out but already beat by A15 in nexus10. "Speed Enhanced" A320 is already beat here in A600 also. It barely catches the T604, and is smoked offscreen 1080p and will LOSE to T4. A330 coming on S800 won't change this, but it may get close. Nexus was the first device to use A15 IIRC. Exynos5 was the first to feature an A15 which is in nexus10. It just came out 4 months ago and ONLY in dual until octa etc hits. Your comments make no sense. I gave links to tons of benchmarks above, where are yours? I'd like to read them :)

" Tegra 4 Performance:
NVIDIA shared a bit of performance data generated from a 1.9GHz Tegra 4 reference tablet. CPU performance is understandably higher than anything we’ve seen from anything ARM or Atom x86 based thus far"
Either anand is an idiot, or you're wrong ;)

Links to currently available Krait beating A15 please. :) I'd be surprised to see it catch the dual, and there is no quad A15 device yet (which T4 is, so is Octa, etc). I'm not aware of a shipping A15 Quad in any product (again, how can T4 be old when no A15 quad exists yet?), but based on dual A15 benchmarks vs. Krait, I don't think a krait will catch A15 this year (including S800).
