ASUS Transformer Pad Infinity (TF700T) Review
by Anand Lal Shimpi on June 25, 2012 3:00 AM ESTWiFi & GPS Performance
With the Transformer Prime ASUS moved to an all-aluminum construction but did little to focus on maintaining RF performance. The Transformer Pad 300 addressed WiFi and GPS performance by moving back to an all-plastic chassis, but as the high end in ASUS' Transformer stack aluminum was a necessity for the Infinity. The compromise is simple: a strip of similarly colored plastic across the top of the tablet, behind the WiFi and GPS antennas.

I performed a number of WiFi performance tests and am pleased to say that overall wireless performance appears to be much better than any previous Transformer tablet. I managed nearly 40Mbps in the best case scenario, but more importantly I was able to maintain 3 - 4x the transfer speeds of the TF Prime at further distances from the access point. I would say the Infinity's WiFi performance is now on par with that of the iPad, and is seemingly better at 2.4GHz.
| WiFi Performance Comparison | ||||||
| Distance from AP | 3 feet | 20 feet (Different Room) | 50 feet (Different Room/Floor) | 80 feet (Different Room) | ||
| ASUS TF Prime (2.4GHz) | 26.9 Mbps | 9.85 Mbps | 13.5 Mbps | 2.20 Mbps | ||
| ASUS TF Pad 300 (2.4GHz) | 26.5 Mbps | 21.8 Mbps | 20.7 Mbps | 21.3 Mbps | ||
| ASUS TF Pad Infinity (2.4GHz) | 39.2 Mbps | 34.0 Mbps | 34.3 Mbps | 10.8 Mbps | ||
| ASUS Transformer (2.4GHz) | 21.8 Mbps | 17.6 Mbps | 18.8 Mbps | 15.0 Mbps | ||
| Apple iPad 2 (2.4GHz) | 35.1 Mbps | 29.9 Mbps | 26.9 Mbps | 10.6 Mbps | ||
| Apple iPad 3 (2.4GHz) | 35.1 Mbps | 29.9 Mbps | 27.9 Mbps | 9.98 Mbps | ||
| Apple iPad 2 (5GHz) | 36.7 Mbps | 36.7 Mbps | 36.7 Mbps | 11.9 Mbps | ||
| Apple iPad 3 (5GHz) | 36.7 Mbps | 36.7 Mbps | 36.7 Mbps | 11.7 Mbps | ||
ASUS still doesn't support 5GHz unfortunately with the Transformer Pad Infinity, so expect problems in situations with a bunch of 2.4GHz spectrum crowding.
GPS performance also benefits from the RF improvements to the Infinity. Although GPS locks are still not as consistently quick as I'd like them to be, the Infinity is generally able to get a signal lock quicker than even the Transformer Pad 300 - even in adverse conditions. While the Transformer Prime can't get a lock indoors or even in some situations in a car, the Infinity manages to do so in about 12 seconds. The shot below is what I saw after 12 seconds of searching for a lock:
To get something comparable from even the TF Pad 300 took well over a minute. I suspect the improvements to the Infinity go beyond simple chassis work based on its behavior.

"The colors and brightness and contrast are better on the TFP."The colors aren’t. Neither are the ppi. Something that actually makes a real impression in most situations—unless for some reason your only usage of a tablet is in bright sunlight.
The TPI and iPad 3—as hardware, only—each have their strengths and weaknesses. To claim one is absolutely better at everything just sounds fanboi-ish. Or, you know, astroturfer-ish (which you happily accuse others of being above).

Sounds like someone is getting paid to Asus to say these things...zappb - Monday, June 25, 2012 - link
I thought this product was Vaporware considering it was annouced around Jan...and still not released but Awesome screen all the same - Look at those Contrast / white / black level numbers, haven't seen a screen like that in years...and at 1920x1200.When you look at the numbers, the significance of the screen has been glossed over in the article, - the only reason I can see for that, is perhaps that resolution sucks on Android, or apps don't scale well etc..
Lepton87 might have a point but the overall feel of the review is to wait for windows 8 tablets when perhaps the resolution will make more sense.

Your being very unfair. 1920*1080 is a great resolution and a big step up. But its not 25*18. That really IS big deal, its more than most 30 inch monitors. Your trying to equate a good improvement to a complete shift. Way to be objective yourself.sawilson - Monday, June 25, 2012 - link
I own them both. I can hold them side by side. It's really hardly noticable at all until you get the tablets closer than one would use them, and once again I'm talking about the prime versus my 32gb verizon 4g iPad that work gave me. I'm happily at work now typing this on my prime because it has completely replaced my Dell laptop running windows 7. The iPad could not do this. The only reason they went with a resolution that high is they have NO CHOICE. iOS is crippled and has to use multiples of the 6 year old iphone display resolution and dimensions. That's why it has a fail 4:3 display like an old television rather than a proper 16:10 display. That's why you have to buy all new apps for it instead of the superior Android solution that mimics what your laptop or pc and mac already do. Just scale things properly. There's no such thing as a "tablet optimized" app. That's marketing. That's apple attempting to justify failure in their mobile OS design by turning it into a positive. You can tell how intelligent a tech review is by looking for terms like "tablet optimized" or "fragmented" or "retina". It means they lack the technical knowledge to understand that's just marketing meant to talk around shortcomings in their own poorly designed device.LordConrad - Monday, June 25, 2012 - link
"That's why it has a fail 4:3 display like an old television rather than a proper 16:10 display."Tablets are designed primarily as consumption devices, which is how most people use them. For such a device, I find the 4:3 aspect ratio to be superior in most respects. Internet Browsing, email, and ebooks all look much better to me on tablets with a 4:3 aspect ratio. Gaming is a wash as I don't have a preference. The only drawback is watching movies as the black bars are larger unless you zoom-in.
I have nothing against Android, I actually prefer the openness of Android, but I much prefer the paper sized 4:3 aspect ratio for handheld tablets.

Anand is such a huge apple fanboy and it shows in his articles but it shoudn'tJunereth - Monday, June 25, 2012 - link
were we reading the same article here?xype - Monday, June 25, 2012 - link
Probably not. Anything short of "I ONLY HAVE SEX WITH MY ANDROID TABLET FROM NOW ON!!" under Final Words is seen as definitive proof of Apple-bias by some, it seems.Cyleo - Monday, June 25, 2012 - link
Before I owned the original TF Prime I was probably inclined to agree with you. However after 6 months of use, I can see Anand's point. Where iOS is polished in almost every possible way, Android is still rough around the edges. Browser performance on Android is excellent when it works, but it also hangs a lot. Engadget for example is a website that constantly brings my TFP's browser to its knees. And I can tell you that constantly force closing your browser is pretty annoying.There is a huge potential for Android tablet, but Asus and Google need to polish the user experience if they really want to compete with Apple.
