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.

Everyone seems so impressed but for me the big elephant is why is the GPU slower than the ipad2's from a GPU company? And to boot the CPU performance isn't significantly faster either? What's going on?Death666Angel - Thursday, December 1, 2011 - link
CPU is pretty fast when you look at multi-core enabled Linpack. Other programs probably don't handle the 4 cores very efficiently.As for the GPU, Apple has been very aggressive in marketing iOS (specifically the iPads) as mobile consoles, so they really delivered in the GPU department. The downside of that is that the die size of the A5 is 122mm² according to Anand (4s review), whereas Tegra3 even with 5 CPU cores only has 80mm² (Tegra3 launched article). :-)

Not sure if they are equivalent tests, but in the ipad2 review, ipad2 scored 170.9 MFLOP which is higher than the Transformer Prime's score of 135.9.I don't think the average consumer cares about how big the die size is, they will however notice the extra GPU performance.
Also, even with the bigger dies size, it doesn't seem to affected battery life either.

GPU:Power VR SGX 543MP2 (iPAD 2) 60 nm
8 Pixel processor * maximum 4 separate address per vector per cycle= 32 addresses per cycle.
Tegra 3 40 nm
12 Pixel processors x 1 separate address per vector=12 addresses per cycle.
Isn't there a secret slot where you can slip in a NV104 processor and give this story a happy ending. Last time I bought an apple was a Apple IIc. (google it), but in this case power's simultaneous multi-threading beats the brawn of 12 processors. (darn). maybe wayne will get smart and 28nm.

There's nothing to be impressed with. It's another poor attempt by Nvidia to rush a product out the door and getting their ass handed by the iPad2's higher optimized design.How embarrassing to let a 1GHZ dualcore SOC spank a 1.4GHZ quadcore Tegra 3.
I don't know people are excited especially that from what we know of the upcoming Apple's A6 designs and iPad 3 will make this thing forgotten very soon.

Any idea as to whether you would be able to hook up a 4g wireless usb modem to the dock on this? It would be awesome to have that flexibility.medi01 - Thursday, December 1, 2011 - link
I hope one day Anand would stop judging screens only on min/max brightness and would do a proper test, that would also compare gamut.Anand Lal Shimpi - Thursday, December 1, 2011 - link
That day will come very soon... ;)Take care,

how do the these stack up against each other?
