ASUS Transformer Pad 300 (TF300T) Review
by Anand Lal Shimpi on April 22, 2012 3:00 AM ESTGPS & WiFi Performance: No Problems Here
The all-aluminum construction of the Transformer Prime unfortunately resulted in WiFi performance degradation in certain situations compared to the original Transformer, and it pretty much ruined the tablet's GPS functionality. The latter got so bad that ASUS eventually removed GPS from the official spec sheet of the TF Prime and is now offering an external GPS dongle for those users who want better GPS performance.
The Transformer Pad 300 avoids all of these issues by being made completely out of plastic (and glass of course). WiFi performance is better than the Transformer Prime and more in line with the original Transformer as a result. Overall I'd say WiFi performance is pretty decent on the 300, whereas the Prime definitely has issues depending on what is between you and the AP:
| 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 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 | ||
Whereas the Transformer Prime relied on two WiFi antennas and a dedicated GPS antenna, the 300 combines WiFi, BT and GPS into a single muxed antenna located to the left of the rear camera:
WiFi is still provided by the Azurewave AW-NH615, a rebranded Broadcom BCM4329 solution. ASUS tells me that depending on supply we may even see the original Transformer's Murata WiFi solution used in the 300.
GPS support is similarly driven by the same Broadcom BCM47511 used in the Transformer Prime, however this time we get much better performance. I hopped in a car (with a metal roof), drove to an area with clear sky visibility and tested each tablet resting on top of the center console, near where you'd find the gear selector in most cars. I created a WiFi hotspot on my phone to speed up ephemeris/almanac download speeds and relied on the tablets' internal GPS to determine my actual location. Here's what the GPS antenna is able to pick up on the Prime after 2 minutes:
ASUS Transformer Prime, GPS Status after 2 minutes
And here's what the Transformer Pad 300 sees after 18 seconds:
ASUS Transformer Pad 300, GPS Status after 18 seconds
Much better. Note that the SNR for the visibile satellites still isn't all that great. Indeed I don't know that I would recommend the 300 as an in-car GPS replacement, but its GPS performance is significantly better than the Prime. Just for comparison's sake, here's what the original Transformer saw after 18 seconds:
ASUS Eee Pad Transformer, GPS Status after 18 seconds
ASUS doesn't actually make mention of GPS support on its landing page for the Transformer Prime 300, and the WiFi-only iPads don't offer GPS as an option either. If you really want a good GPS solution you may want to consider either a smartphone or the LTE iPad.

sigh.....i am neither a fan/hater of apple nor android/asus. i appreciate both sides. having said that, let me try to objectively address your "concerns" even though you do a pretty good job of madly shouting like anti-transformer, apple fanatic.
1. asus had no problem selling any and all transformer prime that it manufactured. they are probably wishing they could manufacture more and faster so they can make even more money. regardless of your take on the transformer's place in the market, asus is making very good money.
yes, the transformer comes in two pieces. and any normal person wanting to carry both pieces would carry them attached, just like carrying a macbook air. the two piece design is supposed to give you the advantage of flexible usage at the cost of less rigidity while attached.
if you are trying to dog on the two piece design, it would make sense to claim that the given design is a bad tradeoff because rigidity is more important than portable flexibility or whatever. but to claim it is bad because you have to carry two pieces around for a "notebook" is just bad logic and an infantile attempt at flaming. you have lost the respect and credibility of any of your logical readers at this point.
2. the transformer with keyboard costs about half the price of a macbook air. that is a pretty concrete advantage to any rational person. not that it would matter anyway because you are comparing two things in different categories. you seem to have trouble understanding the difference in categories.
3. rational people base their purchases on what they need/want and what they are willing to pay for it. perception of whatever is pretty irrelevant. unless you would buy a macbook air because you think it would help you look more like a wannabe artist / hipster. that's pretty ridiculous, right?
4. you can plug your head down a hole and play ostrich, but to the rest of the world the transformer infinity is going to be released in the near future with the known specs. why does it bother you that another product of the same line is coming with some better specs?
as a final note, you should think more about what you write in your future posts, because what you write shows real fast whether you have any kind of logic and critical thinking.

What the.. ?!You don't have to carry both, you've got the flexibility of taking with you only what you need. Neither a pure tablet nor a pure laptop can offer this. how is that hard to understand?
And I don't think it's fit for real work either. But it doesn't have to be, if internet stuff, entertainment, IMs and mails are all you want to do. And Anand already adressed this: give us this form factor with x86 and things might get really interesting.
Listing the Inifinity: Asus has been pretty forward with the specs provided and Anand said it's not available yet. That's perfectly fine and helps to put things into perspective. If "the next big thing" was around you'd want to be told about it, too, instead of spending top $ now on something which might get outdated the next day.

"While every single Transformer released thus far has shipped with 1GB of RAM, the 300 is the first to use 1.5V DDR3-667. The TF Prime used 1.5V DDR2-500, and the Transformer before it used ."The suspense is killing me!

Almost there but no SD,glossy screen (assuming) and the dock is still way too expensive especially for a more budget orientated SKU.Color accuracy is a disaster but that,by now,is to be expected .
That said,why aren't you pointing out any of the drawbacks in the conclusion,always trying to spin it to point out the positive is not what a review should be.

Same complaints from me here. Either I missed it, but the reviewer didn't even seem to mention/complain about the loss of expandable memory in the form of microSD that the predecessors had. If I were to get a tablet, I'd like to be able to use it as an e-reader as well, and with a glossy screen, it just won't be happening. Hell, just using it for anything in a room with lots of windows is miserable with glossy screens and all the reflections.sprockkets - Sunday, April 22, 2012 - link
microsd is listed in the specs for all but the infinity, they might have added it later, just read the articlechi23 - Sunday, April 22, 2012 - link
This model HAS an microSD card slot. It's mentioned in the reviews on engadget and CNET, and listed as a feature on Asus' own site and in product listings (i.e. Amazon)As far as to my knowledge ALL Asus Transformer tablets have an microSD slot built right into the tablet (not 100% certain about upcoming Infinity until it's released). This is part of their standard design, and one of the main features that I've been looking for in my next tablet
I jumped on to post just about this, I don't know why Anandtech missed this in their review, their spec comparison chart on the 1st page is misleading. I was surprised because this was the first review I read on the model and immediately noticed the omission in the chart. All the other sites I mentioned confirm it's still there, I hope Anand will update his review.

No mention of MicroSD in review? I see microSD as part of specs everywhere else.andrewcooke - Sunday, April 22, 2012 - link
should lower/higher leakage be reversed?also, will these things run linux at all?
