ASUS Eee Pad Transformer Prime & NVIDIA Tegra 3 Review
by Anand Lal Shimpi on December 1, 2011 1:00 AM ESTThe Display: Perfect
The original Transformer had a display that performed similarly to the iPad, but was far more reflective thanks to a fairly large gap between the outer glass and the LCD panel underneath. I excused the first generation Eee Pad in the display department because it was good enough and $100 cheaper than the competing Apple solution. The Prime reaches price parity with the iPad 2, and as a result it must meet a higher standard. ASUS doesn't disappoint - the Eee Pad Transformer Prime has the best display I've seen on a tablet to date.
The resolution is a Honeycomb-standard 1280 x 800. The 16:10 panel measures 10.1-inches diagonally, giving it a very similar surface area to the iPad 2's 9.7-inch 4:3 display. The increase in resolution more than makes up for the larger screen however, ASUS delivers 145 pixels per inch compared to the iPad 2's now quite-dated ~132 PPI.
It's not all about pixel density here, the Transformer Prime has better white and black levels than anything else in its class. It also sets the new benchmark for contrast ratio at nearly 1200:1. The huge gap between the outermost glass and the IPS LCD panel has been reduced significantly, in turn reducing glare.
ASUS also has a Super IPS+ mode that drives the display to a class-leading 683 nits. The Super IPS+ mode obviously draws more power but ASUS recommends it if you're trying to use your tablet outdoors. In our review of the PlayBook we found that 600 nits was really the cutoff for usability in sunny conditions, and ASUS easily exceeds that. It's also worth pointing out that while Super IPS+ increases black levels as well, the resulting contrast ratio remains the same.

Viewing angles are absolutely awesome. Yes this is the same ASUS that let us down with the UX panels but it definitely got the panel right when it came to the Transformer Prime. Fingerprints are still going to be evident on the display but they don't seem to be as bad as on the original Transformer, and they do wipe off easily. This time around ASUS bundles a microfiber cloth to aid in keeping your Transformer looking fresh.
ASUS, Apple and the rest of the tablet world are in hot pursuit of even higher resolution panels, the problem is yields on these small 1080p and 2048x1536 panels just aren't high enough yet. The Android crowd will have to wait, although Apple is apparently pushing very hard (and trying to buy up a lot of inventory) to deliver a "retina display" equipped iPad 2+/3 by Q2 next year. I'm hearing Q3/Q4 for everyone else and it's still not a guarantee that Apple will be able to meet its aggressive targets either at this point.

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.
