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.

It actually feels really good. Hold it one handed in landscape mode and you'll get tired quickly, use it in portrait and prop it up on your chest and it's golden. It's not too big and heavy but you just need to prop it up against something for extended use.Take care,
Anand

Still sounds awkward to me.This is the kind of thing that intrigues me though, when it comes to "tablets". I'm one of those people that doesn't get the tablet thing, but I'm curious. This would be a good way for me to try one out, if I had a spare $600+ anyway. Which I don't right now. I could check out the tablet, and use it as a netbook/ultrabook if I didn't like the tablet option.
Coolz toyz will grab us by the privates, even when we know better. Or think we do.
:D

http://www.nvidia.com/content/PDF/tegra_white_pape...According to nVidia's documentation, Tegra 2's GPU only supported FP20 in the pixel shaders. Has this been improved in the Tegra 3? I believe at least FP24 is required to officially support DirectX 9, so remaining at FP20 would presumably prevent Tegra 3 from being supported in Windows 8. Unless Microsoft intends to make an exception?

"The X button acts as a tap/click on an icon (yes, NVIDIA managed to pick a button that's not what Sony or Microsoft use as the accept button - I guess it avoids confusion or adds more confusion depending on who you ask)."I'm not sure I'm reading it correctly, but Sony actually uses X as the accept button. It's just not in the same place as the one on that Logitech controller.

Thanks for the detailed write up, Anand! I'm looking forward to picking up a Prime when they reach the UK in January.ATOmega - Thursday, December 1, 2011 - link
Thanks for getting the review out so quickly! Still hoping to hear more about GPS, but I realize it's tough to fit it all through in such a small window.I recently sold my iPad2 to cover some of the cost of pre-ordering this tablet. My biggest frustration to date has been having no viable Android tablet to date and being forced to us iOS in the meantime. I've never felt so emasculated by an operating system!
By most measures, it looks like the Transformer Prime is consistently equal if not slightly better in most regards to the iPad2. Bearing in mind that it runs at a higher resolution when comparing performance numbers.
I have to agree, anyone who has been on the fence over Android tablets can probably come down now. It will be a year at the very least until we see a similar combination of build quality, screen quality, performance, consistency, etc... for Android again.

Now you get to feel emasculated by lack of software.ismailfaruqi - Thursday, December 1, 2011 - link
Anand, does Tegra 3 support OpenCL already?Loki726 - Thursday, December 1, 2011 - link
