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.

So, I understand that you can only do so much in one review, but come on...Where are your physical impressions of the device? I understand that the exterior is virtually identical to the Transformer Prime, but still. It'd be nice to even get a "go see the Tranformer Prime review for my detailed impressions on build quality, etc." Where are the battery life figures with the dock? I know it takes a lot of time to test everything, but you waited much longer after all the other review sites to post your iPad 3 and rMBP review. If you don't have a problem waiting on the Apple products, why rush this one out as soon as the NDA lifts?
Sorry if it sounds like I'm whining. I just want the same kind of coverage devoted to Android's new flagship tablet as I saw with the new Macbook Pro or that I saw in the iPad 3 review. Both of those had reviews that were twice as long. Granted, the rMBP (love that acronym you used btw) was a very large upgrade, but the iPad 3 didn't differ appreciably from the iPad 2 in any area other than the screen, similarly to how the Infinity differs from the Prime.
Other than not covering the build quality aspect, though, great review! I really want to see one of these things in action and compare it to my iPad 3 and see how it stacks up. I know the pixel density isn't on par with the iPad, but I'm getting rather tired of the iOS UI on a tablet. I wish I could have some good widgets.

Why is Windows and Microsoft mentioned so much in the article? This article should have been reviewing the updated Transformer Prime running Android.Please keep the Microsoft fanboy rants in their own articles so that we can ignore them easier.

TF Prime is taken off market or is going to be cheaper, then will the other plastic body ones be cheaper???Possum - Monday, June 25, 2012 - link
Did ASUS change anything with the way their tablets are assembled and filtered through QC? I went through one Transformer Prime and three Transformer TF300's, and all had horrible backlight bleed issues.fic2 - Monday, June 25, 2012 - link
Is it just me that doesn't really see the use in a rear facing camera? Holding up a big tablet (compared to a phone or actual camera) to take a picture is kind of awkward. I just don't really see the need for my tablet or laptop to have a camera other than for skype, etc.Tujan - Monday, June 25, 2012 - link
How did the Internet (Browser) benches get Benched. By which Internet connectivity type being utilized ?- Wi-fi
- Tethered Phone
- Some other
There was not any USB port said on the Tablet . Unless I missed this spec. somewhere. I have not seen any HDMI Wimax (via Internet Service Provider). In order to run a wireless connection.
Is this intended to be marketed this way. A localized Internet device via wi-fi etc. Certainly looks intentional w/o a USB connector.
Did not see a processor percentage for use of HDMI to external Display/HDTV either.

P.S. Idea being is this being marketed to that you/me/us/we .. can go "shopping" for wi-fi spots ?Ryan Smith - Monday, June 25, 2012 - link
All of the browser benchmarks were over WiFi.sonelone - Monday, June 25, 2012 - link
Please review the N56VZ next. It is a very capable laptop and offers Macbook Pro level performance at $1300.Godofmosquitos - Tuesday, June 26, 2012 - link
Any word on when the Infinity Pad we're actually waiting for will arrive? I ofc mean the 3G version of this device, sporting Qualcomm's S4 Krait instead of Tegra 3, likely sporting both better performance and much better battery life than what we see here...
