ASUS Eee Pad Transformer Prime & NVIDIA Tegra 3 Review
by Anand Lal Shimpi on December 1, 2011 1:00 AM ESTThe Honeycomb Experience
With Ice Cream Sandwich around the corner it's not worth it to spend too much time on Honeycomb, however the first owners of the Transformer Prime will be stuck with Honeycomb. Although NVIDIA has already demonstrated the Prime running ICS, I wouldn't expect to see the ICS update available to end users until January at the earliest. That's assuming there are no unexpected delays or bugs in the process of course.
Honeycomb has matured nicely over the past year and combined with the faster Tegra 3 SoC, the experience is significantly better on the Prime. Everything is a lot smoother and responsive, even compared to an up-to-date vanilla Eee Pad Transformer. ASUS is pretty good about not weighing down the Prime with bloated garbage so the out of the box the experience is pretty good. There's still a hit if you enable live wallpapers but it's not nearly as bad as it was on Tegra 2.
There are still little annoyances that plague the OS. For example, bringing up the task switcher menu isn't always instant, and performance does slow down if you've got some power hungry apps running in the background that need quitting. The build of Honeycomb on the Prime allows you to quit apps from the task switcher menu by tapping the X next to each app. Unfortunately the taps don't always register immediately, leading you to double tap and sometimes unintentionally closing other apps.
Scrolling in the web browser is pretty smooth, there are occasional hiccups but overall the experience is good.
While Honeycomb still has its quirks, Tegra 3 and the Transformer Prime make the experience so much better. Taking a page out of the old WinTel handbook, sometimes the easiest way to solve a software problem is to throw even faster hardware at it. From what I've heard about Ice Cream Sandwich though, it may bring the added polish on the software side that we've been looking for. We'll find out soon enough.

Exactly my reasoning, and it's easy enough to see that the Transformer Prime boasts better features like GPS, camera and display.After having owned an iPad2, there must be a reason why I want this thing. And it's for all the things Apple decided to fleece me on so that they could jack up their margins.
I never liked Apple in the first place, but it's obvious they don't want to truly compete with the Android OS.

I was really hoping Nvidia would have something special with kal-el. This is pretty horrible when compared to hardware that has been available for about a year.It seems that the Nvidia-equiped tablets should be targeted at a much lower price point. They definetly should not be in the top tier tablets. I can see them selling at $300 or less.

Don't forget the display brightness. I don't think that the processor makes such a huge difference in power consumption, but the display on the Prime is much much brighter than the display of the iPad, and this will consume a huge amount of power. It's also brighter than the display of the first gen transformer, and the prime has a quad core and it gets the same or higher battery life than the first gen, I think that's really a big improvement.And if you want to use a tablet on the go, outside the house, you really need the brightest display possible. And as you can see in the picture, the difference between the sunlight visibility of the iPad and Prime is like day and night. Therefore I at least, sacrifice the 3 hours less battery life.

The display surely only uses more power if you drive it at a brighter level?And a well-designed tablet should have a light sensor, and should do a good job of auto-calibrating the brightness to the environment, so that most of the time it is NOT running the screen in bright mode. After all, that's what we expect regarding the core --- we throttle CPU when it's not needed. So, sorry, I don't think this is an acceptable answer.
I continue to state my original thesis --- I suspect that DRAM power is substantially more important than most people believe, and that one of Apple's advantages is that they ship iOS devices with minimal DRAM. This is obviously a hassle for developers, and even for some power users, but that's the tradeoff one has to make.
(Also what's the story with Android and VM? iOS does NOT do any "write" swapping --- code is paged in, but data is not paged out, and I expect that this is a power issue, nothing else --- Apple doesn't want the power hit of swapping.
I thought Android was like this --- did not write pages --- but I have read stuff recently that said no, it is now using standard desktop type VM, which is likely also a power sink.)

nVidia's solution is actually much more sophisticated than that. It's similar to a method Intel started using a ways back for laptops.It's not just auto-dimming the entire screen; it's auto-dimming every pixel individually. There is fine-grain control over the LED backlight of the display. Areas in each frame that contains black will now not only have the LCD crystal for that pixel in a "block" mode, but it will also have the backlight for that specific pixel dim.
This actually produces benefits other than just battery life; one of the biggest problems with LCD's is that blacks aren't really black because the crystal isn't able to block 100% of the backlight.
By dimming the backlight, the parts of an image that is supposed to be black will be closer to true black. This improves contrast and provides for more accurate pictures.

how shall this work if the backlight is created by an LED array at the edge, which almost all smaller (<20") displays are. So with an edge lit backlight you can't reduce the LED brightness block wise.This is different if the used panel has a full array of LEDs, which is expensive, more power consuming and thicker, so a no go on a mobile device that thin. And neither Intel nor Nvidia have impact on this, because this requires a different panel.

BenchMarking App's are not yet optimized. So please wait !!fteoath64 - Friday, December 2, 2011 - link
Why would you want a Win8 tablet ?. Its slow, heavy, short battery-life and probably cost 50% more!.You are better off with a mid-range slim laptop which you probably have. So unless you grab one of these or already have an ipad, you have no idea what a tablet can do for you.eddman - Friday, December 2, 2011 - link
You might have a time machine then, cause right now there are no win 8 tablets, let alone ARM based ones.tipoo - Thursday, December 15, 2011 - link
"Its slow, heavy, short battery-life and probably cost 50% more"Citation needed, citation needed, citation needed, and citation needed respectively. None of us have tested finalized W8 table hardware yet, unless you are from the future.
