Nvidia is making a big deal at this year's MWC of proving its bold claim that the upcoming Tegra 4 system-on-chip is "the world's fastest mobile processor." The first benchmarking runs show the company's new silicon comfortably outpacing every piece of current-generation hardware - sometimes more than doubling the previous high watermark. Nvidia's biggest competitor, however, remains unperturbed.

Looks like Nvidia got some serious competition from Qualcomm.

good, competition is good, especially when it involves great increases in performance/battery

I am happy to read about greater performance from the chip itself, but I wish they would focus more on efficiency now.

Give me a Note 2, N4, HTC One, that can last 2 full days with heavy use. THAT is something to brag about...
I know, there are many other things that affect this (screen, especially) but the chip itself would be a great start....

Pics or it didnt happen.

Mobile processors dont interest me if its in a phone or a tablet, Put it in a console on the other hand and you have me interested.

The SoC is not the part responsible for most of the consumption on our devices...mostly it is data transmitting/receiving and the screen.
With phones having wifi/gps/LTE etc almost constantly connected, even when the SoC is technically idling - which is the case for pretty much anything other than gaming or modifying pictures/videos etc - we have massive power draw.

Better SoC, big-little architectures (that don't overheat, thought that was the point to begin with) etc, shave off a portion of a portion of the issue.

Every phone's screen is what drains the battery. Not the chip.

What phone last 2 days under heavy use?

the phone screen is nothing compared to the CPU. Otherwise, the Note 2 would have the worst battery life of everything.

Droid razzr HD (i think that's the one) is good for about 14 hours of straight use. amazing battery life

"The real reason to buy the Razr Maxx HD is its massive 3,300mAh battery, which is unfortunately not user-removable. Of course you'll likely not care since Motorola claims the Maxx HD will provide 32 hours of performance. Specifically, you'll be able to stream YouTube video for up to 13 hours, or enjoy GPS navigation for 8 hours. Indeed I can vouch for the Maxx HD's impressive stamina. On the CNET Labs Video playback battery drain test, the phone lasted for 893 minutes (14 hours and 53 minutes). That's much longer than the Samsung Galaxy S3 (530 minutes) and Maxx HD (577 minutes). That said, the first Droid Razr Maxx lasted for a longer 916 minutes (15 hours and 16 minutes) on the same test which is likely due to the Maxx HD's bigger screen and faster processor."

Remember that the GS4 will have the Snapdragon 600 so in that case, Tegra 4 wins.

 

[Nenkitsune]

Meh, non-removable battery and motorola/verizon kill that phone for me. same with the camera quality.

I run pandora for 12 hours straight every day and by the time I get home my phone still has 30% minimum. (Note 2)

Regardless, I am happy to see healthy competition with mobile cpu companies.
One thing that is bothering me is that samsung is most likely not going to use an amoled display, nor an exynos processor.

I can only hope the note 3 will have those.

 

[boot318]

Didn't they say "Our 600 is going to beat the Tegra4"? They are changing that song after seeing it. Oh! It's the 800 series. Okay.

Doesn't really matter as tegra4 isn't any closer to oems than than the 800.

Who the heck stares at benchmarks on their phone? I know I sure don't. Sure i'll do on a PC, but on a phone? As long as the experience is great i don't care what's inside. I use an iphone 5 right now, but the only things i'm concerned about are 1) Experience 2) Ecosystem 3) Battery life. I sure as heck don't run openGL benchmarks on my iphone, that just sounds completely ridiculous to me. The UI is snappy and easy to use, so that's good enough for me.

I haven't seen any data on Tegra 4 battery life, I haven't heard of any design wins either. I guess we'll see this summer.

S4 was destroying Tegra 3. It will be hard for nVidia to beat Snapdragon 800 in just a single generation, xD

 

[Shadeh]

I must say when it comes to phones a limit is quickly reached where you can say more power is not needed. It seems as though there are people out there who really take gaming seriously on their mobile or tablets. That is something I can't understand. The gaming on a PC for me is million times more enjoyable so I couldn't give it a second thought. The only thing I don't mind on phones would be 2d games or stuff like tower defence when waiting.

The cool thing about the tegra 3 was its power saving core which was able to stay in stand by and only losing 1% over night. When I used my tegra 3 one x though I got really frustrated. You could see the battery % drop like there's no tomorrow. I'm sure this one will be easier on the battery.

But as previously mentioned in this thread. For mobile devices sufficient power is there. Let's concentrate on the battery now, please ? :-(

The stock A15 design Nvidia is using is faster per clock than the original Krait design. The new Krait revision is faster per clock and has a higher clockspeed at the same TDP. It has yet to be seen if the increase in IPC will be enough to keep up. The major advantage for Qualcom will probably be power consumption. A dual-core Krait stays within the power budget and TDP of a phone while the dual-core A15 Exynos from Samsung doesn't fit well. The fact that Nvidia is marketing an A9 chip as a lower-power Tegra 4 seems to hint that they expect the Tegra 4 to fit in tablets, but want to market the Tegra 4i in phones as though it were the same chip design.

The chip designs to watch are the quad-core BIG.little architectures. Samsung's 8-core chip (anand article here) offers better power consumption in phones by keeping all the A15 cores (except 1 for high performance demands) off and using the very power-efficient A7 cores instead. In a tablet or laptop, the big cores can be used with less fear of breaking the TDP budget and all 8 cores can be used at the same time once Samsung gets the firmware ready.

big little is to save power lol... a quad core a15 and a big little a15 running the same task at the same frequency and voltage will have the same temperatures.. the big little just saves power on less demanding tasks..like idling...

Can't wait. Consumers wil be the victor from this battle.

Yep, take a look at mobile platforms from just 2 years ago, and look at what's our now, and what's coming out over the next 5-6 quarters. There are really some impressive improvements going on in the mobile world.
