ASUS Eee Pad Transformer Prime & NVIDIA Tegra 3 Review
by Anand Lal Shimpi on December 1, 2011 1:00 AM ESTVideo Playback: Blu-ray Quality in a Tablet
One of the biggest issues with Tegra 2 based tablets and smartphones is a limitation that prevented hardware accelerated decode of any high profile H.264 video content. You could still decode the video but the additional stages of the decode process were left to run on the CPU, which in turn resulted in substantially lower battery life. NVIDIA has completely addressed the problem with the Tegra 3's video decoder, which is now capable of decoding 1080p H.264 high profile streams at up to 40Mbps.
The Honeycomb video player (Gallery app) will play .mkv files by default but if you want to throw on a .m2ts file you'll need to grab a third party player. DICE Player for Android supports Tegra 3's hardware acceleration, making it a good option if you want broader file compatibility.
Android File Transfer won't push over a file greater than 4GB so the first thing I tried was ripping a portion of A Quantum of Solace (BD) and sending over a 40Mbps High Profile 1080p MKV of it. The resulting 10 minute segment was 2.8GB in size and played beautifully on the Prime. There were no dropped frames and no hiccups, it just worked.
External NTFS volumes are supported and the sdcard file system supports files greater than 4GB in size, so I copied a 15GB 1080p Blu-ray rip of A Quantum of Solace from a USB stick to the Prime. I had to use DICE Player to get audio but otherwise the clip just worked. The biggest pain was copying the huge file across, but it'd be quicker and less painful than a re-encode on most systems.
To really test my luck I threw a few of our media streaming test files at the Prime. Our 720p60 test file worked perfectly, while our 1080p60 test case was mostly smooth with the exception of occasional slowdowns. I tried playing back a 1080p30 VC1 file however I couldn't get it to play back with hardware acceleration. Some of the more exotic combinations of features and file types wouldn't work, although I suppose that could be the fault of the playback software.
As far as I can tell, Tegra 3 and the Eee Pad Transformer Prime in particular are capable of playing back 1080p24 Blu-ray class video. Total NAND capacity is the only thing limiting us from just dumping a raw Blu-ray rip onto a tablet and playing that directly. Pretty much any HD rip you make yourself or find online will likely work. You may still need to invest in a good third party player to ensure things like subtitles are properly supported however.
I'm pleased with the state of video on the Prime. It's not HTPC level, but we can finally play really good quality video on an Android tablet. I suspect it'll be one more generation before we get tablets (and associated software) that will just play anything you throw at them.

What the hell are these "Normal","Power Saving", and "Balanced" labels?I'm not going to read a single page more of this article. The benchmarks mean nothing when not explained.
I'm using a transformer sans prime, and have no such ability to choose some type of profile, or whatever the heck they are.
I've never been frustrated or a tad bit angry with an a and article before....but I suppose there's a first time for everything, eh?

WTH?, there is a whole page explaining the 3 power profiles. Please read the articleAbini - Thursday, December 1, 2011 - link
I read the review by Josh Miller on CNET and they also had a model that had WiFi issues. I am looking to replace my old clunky laptop and an ereader with this model, so I'm hoping it is just a fluke, but with two different reviewers getting "bad" items, that makes me suspicious. Like the Apple denials of iPhone antenna issues, I don't want to buy version 1.0 and find out that it can't handle better than 2MBPS connections due to a hardware issue.I'm holding off for few months to see how the WiFi works for the rest of the people before I jump onboard.

That's not good.I was going to get on the preorder list for this...sounds like it's finally a good Android tablet (or at least on par w/ the Galaxy Tab).
Wish it had a built-in USB port, but there's an inexpensive dongle for it...

Battery life is just wrong on these things. An ipad 2 would never get 12 hours battery life. After using one for 3 months you'd be lucky to get 9 hours in that same test. Real world usage goes down to about 6. Gaming, less than 2 hours, again after a few months of use. That's just annoyingly bad for such an expensive device. This model HAS to at least beat that. By all rights it should be doubling that. These things are too weak, too light, and run out of juice too quick. They should have at least double the battery capacity. The fact that they dont even offer a higher capacity battery really irks me.I rant and rave about how my ipoop can barely even load a youtube video. I set it down so it can buffer for a few minutes, and I come back and the screen is locked and when I unlock it I have to reload the stupid video. These things are just so much junk its not even funny. As I said all along ...

My original iPad-1, pre-ordered and heavily used since day one, plays video for 11.5 hours straight...still...with 3G off and Wi-Fi on.YouTube videos don't reload when the display locks, at least not with iOS 5, and video playback takes only 2-3 seconds to start for me.

First, congrats to Anandtech for a great review as always, despite the time constraints.So here's the takeaways I get from reading this:
1. Asus really managed to get a well designed piece of physical engineering out the door and in people's hands. That's better than HP, Motorola and a host of other iPad wannabees. Well done.
2. The screen is nice and apparently class leading. Again, well done, although you shouldn't pat yourself on the back too much for surpassing something that Apple built two product cycles ago and will likely blow away next quarter. Just sayin... For right now, it's the leader, and will continue to be in 3, 2, 1....
2. As with everything in the Android world, it was necessary to ship early rather than complete. With Ice Cream Sandwich literally making the scene now, it would have been a great addition to this machine. As it stands, it's yet another upgrade users have to do...assuming they every get it which is sadly the way of things with Android upgrades from manufacturers. Lots of promises, poor execution. I could understand it if the issue was shipping ahead of Christmas but the window for that was a number of weeks ago, not early December. Even Amazon was pushing it by having the Kindle Fire launch around Thanksgiving.
3. The NVidia Kal-El chip has been the talk of tech blogs for months. Quad-core + one low power core sounds pretty cool. But a chip clocked at 1.3 Ghz with 4 cores is barely outrunning a 1 Ghz dual-core A5 that Apple designed a year ago, and gets mostly worse battery life despite the smaller die size of the SOC. Really Nvidia? This is the best you got? The real story should be how Apple is managing to get their performance out of underclocked CPUs and still gets better battery life.
4. Which brings me to video. Again Nvidia, this is your core competency...graphics. When your butt is getting kicked by a product designed a year ago, that tells me you still have a ways to go in the mobile space before you are truly competitive. The playing of m4v and high profile formats is way cool...props there. But you're still getting boat-raced in the one space where you should be king. C'mon, man...
Yes, I do like my iPad but I also want these tablets to get better because it makes the entire industry better. But watching some of the comments in these parts strikes me of the upmost in homerism. True, some like being able to warp Android into whatever they want, but many of us grownups have families and frankly, things to do. I don't have the time to fool with tweaking stuff I used to 20 years ago. I want the thing to work the first time. Which brings me to my next point...all that configuration potential is terrible for certain applications. I have an iPad for my special needs son and iOS is the gold standard for special needs applications. Why? Because my son can understand it and not break the thing. Sometimes I don't think many of you realize how hard simplicity really is to achieve. I could never put an Android device in front of him without him putting through a freaking window.
Lastly, iTunes isn't the world's greatest app but considering all the things it has to do, I amazed it works as well as it does. Most of you have no idea how difficult it is to manage a storefront of its size communicating to what's probably the world's largest ERP system. Is is the best in performance? No, it could be much better. But it chokes on 200 gig of music? My library of 420+gigs of lossless music + another terabyte of ripped video content would like to have a world with you.
Ice Cream Sandwich looks cool and we'll see Windows tablets sometime in 2012. But for right now, I still haven't seen anyone who can mop the floor with the iPad, no excuses.

One of the first comments that makes sense.I see so many people saying that they would never get their parents or kids an iPad. Hate to tell you, but you're not doing them any favors by getting them an Android tablet with the possible exception of the Kindle Fire. You've missed the entire point. Nobody except uber-geeks wants to deal with all that stuff. Say what you will, but for most people, iTunes works just fine and has a low learning curve.
Now, ICS may be a better much for this tablet, but it's hilarious that, in terms of performance, the iPad beats an nVidia quad-core, has better battery life and even whips it in graphics performance. You've finally matched the original iPad and you're proclaiming victory?
Regardless, why would I care about all quad-core vs. single-core as long as the darn thing works and is fast enough for me to not notice? My Galaxy is a pain in the *** compared to my iPad-1 and far less useful.

The original iPad? It was the iPad 2 in the charts.TareX - Friday, December 2, 2011 - link
You said most what I wanted to say; I too have a busy career and don't have time to switch ROMS, and do the tweaking I used to do with my purchases. I have an Atrix and it's running Froyo for heaven's sake.I will be holding out till ICS gets released with the Prime. But I'm getting the Prime. I can't wait till next year; and I know I won't be getting an iPad.
