ASUS Eee Pad Transformer Prime & NVIDIA Tegra 3 Review
by Anand Lal Shimpi on December 1, 2011 1:00 AM ESTFinal Words
Assuming the WiFi and minor dock issue I encountered aren't widespread (ASUS insists they aren't), I am comfortable calling the Eee Pad Transformer Prime the absolute best Android tablet on the market today. The hardware looks and feels great. ASUS picked the best display possible and married it to some really good industrial design. I was impressed with the styling of the Zenbook, and the Prime continues to position ASUS as a purveyor of high quality mobile devices.
At the same time, NVIDIA has finally delivered an SoC capable of delivering the sort of smooth experience we'd expect from a $500 tablet. Honeycomb was a great first attempt by Google at a tablet OS, but Tegra 3 really makes the whole experience complete. Everything you'd expect to be smooth, is finally smooth. Video playback is no longer an issue, the Prime and Tegra 3 can finally play back virtually anything you'd want to throw at it. Thank goodness.
As good as the combination is today, I admit that I still can't wait to put Ice Cream Sandwich on this thing. Even more polish on the OS side (and the absence of any hardware issues during the testing process) would've easily catapulted the Prime into editor's choice territory.
Battery life is the big unknown at this point. At worst it's roughly on par with the old Eee Pad Transformer. I'll know more in the coming days, but 9 hours of continuous use isn't bad. The question is how much better will it be as we start playing with the available power options? I'm also curious to see what having four cores does to web page loading performance. There's clearly an impact on JavaScript rendering, but what about the overall real world experience? In my testing I was limited by the WiFi issue I mentioned earlier, but I hope to have an answer to this soon enough.
The inevitable iPad comparison is, well, inevitable. I still firmly believe there's not a whole lot of iOS/Android cross shopping. If you want an iPad, that's what you should buy. Android isn't an iOS substitute, just as iOS isn't an Android substitute. You can do similar things on both, but personal preference will really determine what suits you the best.
I'll have more coverage on the Prime over the coming days, but if you're making your decision before then: this is the Android tablet to get.
Update: ASUS has removed GPS support from the Prime's official spec sheet. Check out our update here as well as our follow-up to the review.

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.
