CPU Performance

Tegra 4 features the fastest ARM CPU configuration of any device we've ever tested. There are four Cortex A15 cores inside running at up to 1.9GHz. Note that 1.9GHz is the max CPU frequency even with all four cores active. Tegra 4 is an absolute beast. Do keep in mind that the Tegra 4 is actively cooled via a fan inside Shield, which does give it a bit more thermal flexibility than what we'd normally find in an Android tablet.

CPU-Z incorrectly identifies Tegra 4 as Tegra 2, the cores and frequencies are accurate though

Looking at even our limited CPU performance suite, the combination of ARM's first 3-issue out-of-order architecture, incredibly high clock speeds and a big chassis to dissipate heat is extremely evident. SunSpider performance is in downright low-frequency Core territory, and it just blows away anything else we've seen from any device running Android or iOS. The comparison in Google's Octane benchmark is still strong, although the Nexus 10 comes very close. Finally, we see great performance in Kraken as well. It's a shame we haven't seen Tegra 4 used in more places, because honestly this thing could make for a killer Windows RT device.

I threw in some of our early Snapdragon 800 performance data, and it looks like Tegra 4 still pulls away with a win in that comparison as well. ARM's Cortex A15 is just insanely quick. Again, there is a fan in Shield - that definitely helps make this possible.

For what it's worth, there's no funny CPU clock boosting going on upon launching any of these tests.

    My tablet is 1.3 kg and I have no problem using it like a book. At first I lent it against my leg, desk and bed until I got used to the weight. If 500 grams is to heavy for you try resting your elbows on an arm rest while your playing.

    The device is very elegant. Nvidia is providing gaming with VNC. Try using an openGL game on a wired network with RDC. It sucks and it uses PC hardware. This is an 500 gram handheld android device that lasts for 10 hours.

    Please don't be "That Guy." There are links to Dailytech in the side bar if you must use that tone.

    Ergonomics play a big part is determining if an item can be held for a long time. It is about the weight distributions. E.g. holding a stick of 0.5KG as compared to holding a spherical item of 0.5KG give totally different feeling.

    Your irresponsible choice of words like "junk", "bias", "ugly" simply shows your prejudice.

    You clearly don't handle objects of differing weights, sizes and shapes very often.
    A 30Kg object can feel lighter than a 15Kg object if it's easy to hold, well balanced and controllable shape if the 15Kg one is awkward.

    I remember when Anandtech had almost exclusively readers with an IQ >90.

    I miss those days. Guess when you become popular, common sense comments go out the window.

    Haters gonna hate. Never heard of weight distribution?
  • Refuge - Wednesday, July 31, 2013 - link

    I don't see how that could have been considered a rant.

    Troll perhaps?

    Maybe you should put down the Xbox controller and pickup a dumbell or barbell once in a while.
    Or would that hurt you quest to become the ultimate dungeon master?

    What is unbelievable is how clueless and stupid some people can be. You have no idea what Brian and Anandtech are about, you are blatantly rude, and are so ignorant about weight and balance I'm surprised you can actually type. And if Anandtech feels that this response to your post goes overboard I'm sorry, but it is no more offensive than someone calling Brian dishonest in any way, and I don't believe in letting bad behavior go unchecked.

    I used to swing a 1-lb hammer all day long, and there are hundreds of thousands, if not millions over the years, of construction workers who did the same. That's one pound at the end of a stick, swinging it with one hand, not holding it in 2 hands relatively close to your body. Since you are so ignorant let me point out that 1 lb is 454 grams, and that measurement is for the head of the hammer, not the whole hammer. There ar many workers in many fields who deal with a lor more weight than that, 8 or more hours a day, 5 or more days a week.

    Oh, and by the way, a regular wireless Xbox 360 controller weighs 265 grams. So, what you are talking abut here is a little over 1/5 a kilo more weight.

    I'm sorry that the heaviest thing you lift in your life is a Big Mac and you have no muscle tone. I'm sorry that your Mommy was mean to you all your life and so now you have a bad attitude about everything. Here's a clue though - regardless, you are responsible for your behavior in public, responsible for your physical condition, and responsible for your beliefs. Consider this a wake-up call. Get a clue before you post next time.

    Seriously, a good counselor can help a lot, I highly suggest you find one ASAP.

    Excellent, well said sir!

    People hold 7-inch tabs that are 400-500g with one hand and a funny grip. So a little over a half-kilo with two hands and real grips seems doable.
