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.

Not sure about the discrepancies, however, 2.1 is the latest version and it should be the one tested.Also, iOS 5 brought significantly faster openGL drivers, maybe PCWorld were comparing result from a while ago on the ipad2 and iOS4. All onscreen tests are also vsync limited, so the maximum they will ever score is 60fps.
offscreen is somewhat important, as some ipad2 games can render higher output via the HDMI accessory to an external device.

GLBenchmark 2.1 allows for testing at the same resolution (720p) to enable true apples to apples comparisons of GPUs. There are some slight changes in the workloads as well, so 2.1 numbers aren't directly comparable to 2.0.x numbers.That being said, the iPad 2 should never be slower than the Prime even in an older version of GLBench. I'm not entirely sure what's going on there...
Take care,
Anand

A new version of PowerVR drivers was released some while back (I believe it came with iOS 5) and improved performance dramatically. That may be the issue.GnillGnoll - Friday, December 2, 2011 - link
46 fps is an old result on iPad 2. With iOS 5 the Egypt Standard test is almost permanently vsync limited at 60 fps (2.0.3 is gone from the online database, but the workload in the Egypt test hasn't changed between that and 2.1)araczynski - Thursday, December 1, 2011 - link
if this is supposed to be the next generation of the android tablets, getting slapped around by the ipad2, WHEN THE IPAD3 is 'just around the corner' makes it almost a joke of an upgrade.i don't have any love for apple (pc guy), but i'll be saving my mountain of pennies for an ipad3, rather than bother with an android tablet, have enough random issues with my free DroidX that i couldn't actually image wanting to pay for the 'experience' in a tablet.

If by "around the corner" you meant April or May of the next year than perhaps, based on your needs, you should wait but then if you wait another couple of month you could get the next gen super-duper tablet and so on and so forth. Anyway your life your choice I ain't canceling my preorder based on the Anand's review.gorash - Friday, December 2, 2011 - link
No this is not the next generation of Android, next generation is ICS or Jelly Bean. And iPad 3 is coming next summer.steven75 - Saturday, December 3, 2011 - link
Neither iPad was released in the summer.Ketzal - Thursday, December 1, 2011 - link
I'd like to congratulate on a truly superb review. Given the horribly short time you had to write it and do the testing. You did an amazing job.Your reviews are a true breath of fresh air.
The quality of your reviews make the Engadget and like websites look like total amateurs.
Basically it works like this...if you are pondering a new gadget. Wait for your review. If you say it's the one...it's the one. Buy said gadget.
Live happily ever after.
Congrats, I'll be singing your praises to everyone I know.

You should consider getting a low-voltage brain in your next life since Anand does your thinking for you. This way your battery might last as long as the iPad2's.Anand may be good but regardless of his reviews "Happily ever after" is about 6 months in this industry.
