Fun fact: a 1080p display packs 2,073,600 pixels. The Asus Transformer Pad Infinity (or TF700)? 2,304,000 - or 230,400 more. Most 1080p HDTVs are somewhere around 40-60 inches. The TF700 checks in at just 10. Compared to a 40" HDTV, that's 111% of the pixels in a package that's 6.25% of the size.

The screen may be the real headline feature with the Infinity, but it's not the only one worthy of note. It's still powered by NVIDIA's Tegra 3 "4-PLUS-1" CPU, but it's a newer revision that packs a little more punch. The RAM, too, has seen an upgrade, and the screen is now protected by Gorilla Glass 2. The body retains many of the styling features of its predecessor, the Transformer Prime (TF201), yet it's gained a plastic bar across the top in order to remedy the Wi-Fi and GPS issues that plagued the Prime.

So on paper, we've got more power driving a lot more pixels, and a major flaw that's been fixed. What other changes have been made from the TF201, and what flaws remain - or cropped up in the interim? Read on to find out.


In A Nutshell

Short List

  • Expected availability: July 16 or later in the US, but the date is flexible. Update: As per ASUS, the Wi-Fi variant of the TF700 should come to Europe and Asia Pacific in July or August, and the 3G/4G variant should show up in August or later.
  • Price: $499 for the 32GB model, $599 for the 64GB, and $150 for the dock
  • OS: Android 4.0.3 (Ice Cream Sandwich), plus some light manufacturer customizations
  • CPU: NVIDIA Tegra 3 T33, up to 1.7GHz
  • RAM: 1GB 1600MHz DDR3
  • Display: 10.1" FHD IPS display at 1920x1200 pixels and up to 600nits of brightness, protected by Gorilla Glass 2
  • Camera: 8MP rear (revised and improved from the Prime) and 2.0MP front
  • Battery: 25Wh for tablet, 19.5Wh for dock
  • Dimensions: 10.35" (262.89mm) wide, 7.11" (180.59mm) tall, .33" (8.38mm) thin, and 1.31lbs (594.2 grams).
  • Connectivity: Bluetooth 3.0, 802.11b/g/n
  • Offered in two colors: Amethyst Gray and Champagne Gold (the same as the Transformer Prime)

The Good:

  • The Pad itself has phenomenal build quality. Extremely solid - better than the Prime, even (more below).
  • What happens when you take a fast CPU and fast RAM, and make both even faster? Speed. Demon.
  • The tablet is finally backward-compatible, in this case with the TF201 dock. (Or the TF201's dock is forward-compatible. However you want to look at it.)
  • Asus's customizations are relatively few and tasteful. Most of the widgets are nice and customizations to the control panel are helpful - especially the control toggles and power modes.
  • The company cut no corners with the screen, and it shows; it's just plain beautiful. It's super crisp with no discernable pixels or lines, and produces accurate, gorgeous colors. It's very, very reminiscent of the best-in-class display on the HTC One X, just bigger.

The Bad:

  • The screen produces so much glare it's almost a mirror, and it borderline actively seeks out smudge marks.
  • The dock's build quality isn't exactly "bad," but it does feel a little chintzy.
  • Speaking of the dock, it doesn't seem to... dock... reliably. There were numerous times where it just spontaneously lost connection, then regained connection a few seconds later.
  • For some reason, it won't recognize my microSDXC card, though the TF201 and TF300 both do. Weird.
  • My unit shipped without the Play Store installed. That's a pretty major oopsie, though thankfully it only took a reset in order to fix it. From what I understand, mine was the only one with this issue, but I'd be remiss not to mention it.
  • This is the fourth Transformer in a row in which they still haven't addressed the light bleed.
  • This is the fourth Transformer in a row in which they still haven't addressed the ultra-sensitive, ultra-disruptive trackpad that doesn't recognize and ignore palm brushes.
  • Much more unforgivably, it's the third Transformer in a row in which they put the speaker on the wrong side and pointed it the wrong way for good measure.

In A Nutshell: well, they took the best tablet available and gave it a better screen, more power, and fixed the GPS/Wi-Fi. What do you think?

You Should Buy It If: you're in the market for an Android tablet and can afford it. You'd be hard pressed to find a better choice.

Deep Dive

Design & Build

wm_IMG_1299 wm_IMG_1298 wm_IMG_1297

When I reviewed the Transformer Prime way back in December 2011, I remarked on just how high-quality and sturdy it was. The aluminum chassis combined with light weight inspired more confidence than many of the plastic and/or heavier tablets available at the time, and the lack of give at any edges completed the feeling of quality. The Infinity is very similar to the Prime, and save for the plastic bar across the top, the two would be physically indistinguishable at a glance.

Look closely though, and you'll see the differences. Obviously the plastic on the top is a dead giveaway, but there are other clues. The Infinity is flatter across the back and has more angular sides versus the much more tapered (and virtually side-less) Prime. The Infinity is thicker by a hair (.01") and heavier by a hair (.03 lbs.) Some of the ports and buttons are in slightly different spots, as well. Realistically, the difference on both sides is so negligible you probably won't notice.


wm_IMG_1309 wm_IMG_1311

There are three causes for concern, though. First, the Prime felt great initially but the build on the dock began deteriorating after just a few weeks of heavy use. It's not a disaster and the pad itself still feels good, but it's hard not to factor that into consideration with the Infinity. You've been warned: the build is good now, but how well it holds up has yet to be seen.

Second, as with the Prime, the aluminum back is so stupidly scratch- and smudge-prone that it's embarrassing. Within 10 minutes of pulling it out of the box, there was a noticeable scratch in the back from God-knows-what. That was just the tip of the iceberg, as you can see by the the photos throughout this review. Granted, it's a purely aesthetic complaint, but a substantial one nonetheless.


wm_IMG_1315 wm_IMG_1312 wm_IMG_1314

Full-size the above to see the scratches.

The third problem is a three-peat. I complained about it in the Prime review: "Only one speaker, placed in what is quite possibly the worst spot imaginable. It's almost as if they sat down and said, 'What's the stupidest place to put a speaker?' and then put it there." It was also a problem with the TF300: "As with the Prime, the speaker is on the back.  Which means that everyone who isn't you will be able to attest to the sound quality." I really don't feel the the need to rephrase it a third time, so I'll just say what the hell, Asus? Stop pointing the speaker in the wrong direction.


Those three issues aside, the Infinity is sleek, thin, light, and a pleasure to hold and use even for extended periods. Frankly, I find the less tapered back to be marginally more comfortable to hold than the Prime. In fact, the only real issue is the speaker placement, and by now I'm so used to cupping my hand behind the speaker to reflect sound in that I half think it's perfectly normal behavior.



If this image was to scale, this girl would be Hagrid's daughter.

The display is really the highlight of the show here, and as mentioned in the intro, there are a ton of pixels packed into a relatively small screen - more than twice as many as in the TF201, in fact. But as demonstrated in the past by, shall we say "alternative" display technologies, a high pixel count doesn't always equal a good image. Thankfully, it appears Asus cut no corners with the display of the TF700 - the display is absolutely stunning, and arguably on par with that of the best-in-class HTC One X despite a lower DPI.

At 1920x1200, the picture is incredibly sharp and colors are beautiful and accurate - basically, it's plain gorgeous and I have no complaints in that department. Black levels are certainly good, but they're nothing special. Brightness, especially when using Super IPS+ mode, is outstanding - so bright, in fact, that you can use it outdoors in bright sunlight (that said, automatic brightness sucks terrifically).


I present to you: automatic (not-)brightness.

It's not perfect though - whether because of the Gorilla Glass 2 or because of some coating Asus puts on, the display is highly reflective and insanely prone to smudges. While viewing angles are technically good, they're more or less ruined in any well-lit situation because of the reflections. Unfortunately, there's also some light bleed - though thankfully it's only noticeable when the screen is black around the edges. And while Super IPS+ mode turns the brightness up to 11, it also zaps the battery, and even in medium-lighting situations the reflection/glare is just horrendous without it.

wm_IMG_1319 wm_IMG_1324 wm_IMG_1327

So, all told: 90% of the time the display is simply stunning. 10% of the time you'll be too busy using it as a mirror for whatever purposes to notice just how stunning it is.


None of the newer (Tegra 3-based) Transformers are particularly porky, but as with the TF201, the TF700's dock is quite svelte. Especially at the bottom (where your wrists sit), it almost feels like your wrists are on the table (or your lap) when you're using it. That's partially because it's just that thin at the end, and partially because the taper brings it to a point that seemingly melds into whatever surface you're on.

wm_IMG_1303 wm_IMG_1305

Thankfully, the thin profile doesn't detract from the typing experience, and the keys feel great. They keypad is nice and smooth and the clickpad adequately... clicky. All that said, Asus still hasn't fixed the touchpad issue. Ever since the original Transformer, it's almost impossible to use the keyboard without brushing against the touchpad and causing the pointer to move and click elsewhere. The only solution is to disable the touchpad using the hotkey on the keyboard. I've owned all 4 Transformers, and on all 4, I've ended up just leaving it permanently disabled. Having an entire aspect of the dock be so flawed that it's basically forgotten and unused is bad; letting it go on for 4 iterations is unforgiveable.

Performance & Battery Life

The T33 chip paired with DDR3 RAM absolutely flies. Despite the fact that it has to drive more than twice as many pixels, performance actually feels better than on any other tablet I've ever used, bar none. The benchmarks seem to reinforce the impressive real-world performance:


Screenshot_2012-06-24-16-29-28 Screenshot_2012-06-24-16-39-36

Asus and NVIDIA claim that the T33 chip clocks up to 1.7GHz for one core or 1.6GHz for 2-4 cores (versus 1.4GHz and 1.3GHz respectively on the TF201), yet Smartbench reported the TF700 hit 1.9GHz. Then again, it also somehow reported that gaming performance was worse than that of the Prime despite the higher clocks, so maybe it's just losing its touch.

Even in balanced mode performance was outstanding at all times, and with a mix of performance and balanced (... okay, mostly performance), battery life was around 8 hours of heavy use undocked. Substantial power savings can be had by using power saver mode and/or lowering the brightness. The dock's battery has been downsized a bit by 2.5Wh, but in the real world, that should only result in maybe 45 minutes less life. Frankly, 8 hours undocked is plenty, let alone the 12+ offered by docking.

wm_IMG_1306 wm_IMG_1320

Finally, any connectivity concerns experienced with the Prime have been alleviated by the plastic strip along the top of the tablet. Thankfully, both Wi-Fi and GPS work like charms.


One of the things I've noticed about Asus with the TF101 -> TF201 -> TF700? They're really good at fixing (most of) the things and not screwing with the stuff that's already good. Unfortunately, they've neglected two pretty annoying things: the trackpad and the speaker. The trackpad is an easy fix, and it's irritating that they have yet to do so. The speaker is a much bigger issue, exaggerated by the fact that the company consistently advertises the sound quality.

wm_IMG_1301 wm_IMG_1302

Those two persistent problems aside, the Transformer Pad Infinity is undoubtedly the best tablet the company's released to date. It's also backed by a company that has shown amazing dedication to keeping their product up to date - they're quick to release software and Android updates. In light of the upcoming LTE variant of the tablet, it's also worth mentioning that the Wi-Fi variant will receive updates much more quickly thanks to the lack of carrier "modifications."


If you're considering purchasing an Android tablet today, it's a crowded - but finally mature - market. Even looking only at Asus, the company will be offering the TF700, TF201 (slotting below the 700 once it's up to speed), and TF300 (lowest rung), and that's without mentioning the LTE/S4 variant(s). If you're a consumer, it's a great market to be in. And if you can afford to spring for the Infinity, it's a great device that's got the power, screen, build, and dimensions to make sure it stays competitive for the near future.

  • Joachim Geeraert

    That's 111% of the pixels in a package that's 6.25% of the size.

    • http://twitter.com/Serotheo Simon Yu

      Screen of Transformer is 10 inches.. compared to a 40 in its 25%.

      • Asd

        Field grows ^2 so if diagonal is 4x then field is 16x :]

      • Aaron Matthiesen

        Nope, 6.25% is correct, there is a mistake in the article. Yes, 40" in diagonal is 4x 10 inches. So the 10" TF700 fits 16 (4 by 4 times) in a 40" TV.

        • will

          Does this come with 3G/wifi?

      • Tushar H

         its 6.25% of the total area

  • Loren Cogar

    July 16!?  I was hoping for a launch today!!  

    • Goldenpins

      Hopefully I can order this on Amazon in a few days.. tried now and no luck!

      • Loren Cogar

        There was speculation that there would be an announcement today since Asus asked the first benchmark vids on ritchiesroom.com to be taken down until today.  I am hoping for at least an official release date.  I have the money and am ready to throw it at Asus!

  • Himmat Singh

    A quick note - a 10-inch tab is by no means 4 times (25%) smaller than a 40-inch TV. Screen sizes increase exponentially since they go by the diagonal length. I've not done the maths, but I reckon a 40-inch TV is 16 times bigger than the 10-inch tab.

    • AaronGingrich

      Thanks, fixed :)

  • Himmat Singh

    And is this the Tegra 3+? 1.7Ghz is good but it must be remembered that a certain percent (maybe all?) of the increase in horsepower is there to negate the effect of pushing that many pixels through.

  • Jesper

    Speaker on the wrong side... Maybe it's made for left-handed people? :D

    • John O’Connor

      Maybe they are under the belief that right-handed people will hold it with their left hand, to free the dominate right one.  The speaker placement still leaves something to be desired.  I wonder how hard it would be to relocate to front facing along the bottom where it docks

      • Ian Santopietro

        And then the dock would cover it.

  • crankerchick

    Nice review but the second sentence of the article, I have no idea what you are trying to say. I think you are missing a verb, which kinda matters. I'm excited for the TF Infinity and hope it can knock the socks off the iPad as I will gladly sell my new iPad to come back to an Android tablet. It would have been nice to see a comparison to the iPad in the review, as opposed to just the Prime, but I get it, this is an Android site and that's cool. My main issues with Android tablets right now besides the app space is the stutter in the browser and the lag using the keyboard to type in forms in the browser. I would have liked to see some reference to that--or at least some reference to the user experience in general, besides just saying, "It flies!" If this baby can fix those two issues, I will gladly switch back despite the inferior battery life and app space. I miss gmail!

  • http://www.twitter.com/Genjinaro Genjinaro

    I wish they'd bundle that damned dock. The key feature is the dock (IMHO).


    "The tablet is finally backward-compatible, in this case with the TF201 dock. (Or the TF201's dock is forward-compatible. However you want to look at it.)"
    "The dock's battery has been downsized a bit by 2.5Wh"

    So, the old dock works with this this tablet but there's also a new one with smaller/fewer batteries?

    • AaronGingrich

      Right. The pins/connectors match up, but yes, the body/build is slightly different.

  • Greyhame

    Thanks for a great review.  Two questions:

    1) Is the micro SD slot only available with the dock?
    2) Some reviews claim cheap power / volume buttons with non-repeatable functionality... anything to say regarding this?

    Thanks again Android Police!

    • AaronGingrich

      1) Both the dock and the tablet have MicroSD slots. 

      2) The power/volume buttons feel good to me and have repeat functionality for me  (just double-checked to confirm).

      • Greyhame

        Awesome, thank you. Now I'm just left wondering if the Adreno 255 can hold up at that pixel density, or if I should wait til Asus bumps it up to 3xx. That way I could at least check out the *cough* Windows *cough* tablets.

      • Tvera5314

        Did you ever get the micro sdxc cards to work in the Infinity?

  • Tyler Chappell

    I had ordered the original Transformer Prime in december, but due to it being sold out back then I wasnt going to get it until around february. After seeing the GPS issues, I cancelled my order in January.  Now all that's left is for me to decide how justified buying this over the Nexus 7 is going to be at that price difference The screen and expandable storage are incredibly tempting and 2 key areas I don't want to make much sacrifice, but 1280x800 on a 7" screen is enough to keep me happy at a $250 price point.
    Will a 1200p screen, microSD slot, and slightly less portable form factor and higher-clocked T3 be worth $250? Hard to tell.

  • Whitefangex

    there is only so much glare because of the gorilla glass, its both good AND bad :/

  • Brutus

    Thanks for the review, the TF700 is available since the 22 of Jun in Switzerland

  • Tvera5314

    Did you ever get  your micro sdxc card to work?

    • John O’Connor

      Both of microsdxc 64gbs work in my tf300

      • Tvera5314

        Reason I asked was because Aaron said in  the reveiw in the bad section it won't recognice micro sdxc card although TF201 and TF300 do weird.

        • John O’Connor

          i'm sure with a proper software update this issue will be resolved or may have just been a fauty device.  Most manufacturers of smartphones and tablets only specify compatilibility up to 32gb.  It may have something to do with multiple suppliers of parts wherein they cannot guarantee compatibility overall so they do not mention .or the standard wasn't fully developed when they released said product.  Android natively supports the standard and even old Android phones seem to work with the new microsdxc cards despite official advertising stating that their device is expandable up to 32gb of external storage.  

          So from my standpoit it is more or less a software issue unless of course a particular device or batch of device hardware does not support th standard due to manufacturing concerns.

  • Abbath

    I signed up just to say that was a brilliant review! I love the fact that you critiqued the device whereever it failed and gave full credit where it was due! also touched on good points throughout! I know the Prime had its fair share of issues so Im hoping this beast doesnt fail. It totally has my money at this point thou:)

  • Bryan

    I love my infinity tablet!...but, when it picks up wifi it displays the wifi signal in grey when its supposed to be blue. So it says its connected to a strong signal but it won't actually do anything. Can someone help me???

  • http://www.facebook.com/bill.kiser1 Bill Kiser

    Aaron/others ... just how solid is the keyboard, and can it hold up to more than just occasional tying out emails? I'm a sports writer, and the tablet/keyboard combo would be a perfect solution for me where working space is at a premium. It'd also allow me to reduce my carry load ...

  • Kei

    I just ~LOL~ed when I read the bad! (& here I was peeved at it not having 2GB RAM!)
