WiFi Performance

The mini uses the same Broadcom BCM4334 WiFi controller as the iPhone 5. The WiFi stack supports dual-band 802.11n as well as fallback to 802.11b/g.

Since the mini uses the same WiFi stack as the iPhone 5, you get support for 40MHz channels on 5GHz networks (20MHz on 2.4GHz). The maximum PHY rate supported is 72Mbps on 2.4GHz and a whopping 150Mbps on 5GHz.

In terms of actual performance, this works out to be a maximum of just under 100Mbps on a 5GHz network with 40MHz channels. In practice I wasn't able to get higher than 91Mbps, although Brian managed a very nice 95.7Mbps on the iPhone 5 in his tests. On average I pulled nearly 78Mbps on the mini on a 5GHz network. Move down to 2.4GHz and performance is cut roughly in half (peak performance is around 41Mbps).

WiFi Performance - iPerf

I didn't have any issues with WiFi reception or performance in my testing of the iPad mini. The only complaint I really have at this point is I would love to see more intelligence when it comes to switching between multiple known APs of varying signal strengths. This is a problem on pretty much all devices I play with, they tend to want to stay on an existing network even if its performance drops significantly and there is another, better performing network that could be jumped to. I feel like some more intelligence in this department (testing nearby networks, looking for an ability to seamlessly switch and get better performance) would help mitigate a lot of the inevitable "hey my WiFi is broken" complaints we often see with a move to a new WiFi stack. You could also argue that we just need better designed WiFi deployments.

    Who manufactures the display? I recall in reviews of old this was mentioned, would be nice to see in future reviews of anything with displays this info, thanks. Reply

    Since the current-gen ipad-retina-displays are pretty abysmal in terms of power usage (see displaymate's measurements for example), would it be unreasonable to expect LTPS or IGZO panels to make things considerably better?

    Apple uses Low-Temperature polysilicon IPS in iphone for a reason and it's said that the forthcoming IGZO's would help in power consumption as well.

    I think that Ipad 4 is a "failure" as it doesn't address any of the shortcomings of the 3rd Gen ipad. Namely weight, thickness and reasonably poor visibility in direct sunlight. Though Apple just decided it's not worth the tradeoff to use A6 instead of A6x to reduce the battery weight by a tiny margin.

    Firstly - the iPad 4 isn't a 'new iPad' as much as the iPad 3 was - it's an upgrade a partial way through the year, so it shouldn't be expected to address all 'the shortcomings'.

    Secondly - the iPad 4 doubles the GPU power which addresses the single biggest issue with the iPad 3 - the underpowered GPU. It's significantly faster than any other tablet (as is the iPad 3).

    Also it was important to get all the devices using the lightning connector.

    Yeah its the newer new ipad >.>

    Also known as the biggest ripoff apple has yet produced. Lightning connector (differently shaped usb 2.0), not-really-upgraded soc which brought nothing for the end user. Right? Because iOS is always super smooth? Or is it not?

    Wait wait wait and you're also saying that having even more unused gpu power is a shortcoming that was addressed? Well no point arguing with such logic.

    Especially since the cpu is already outdated. A9's (even with a custom memory controller) are so 2011.

    Man you are a MASTER of facepalms. You initiate a wave of them with every post of yours.

    Bzzt! Wrong.

    Thanks for playing, come back when you've done your research properly.

    Why did you zoom in on the Anandtech website on the Nexus 7, whilst the iPad mini is zoomed out, it makes the Nexus look like it can't display a full webpage which it can!! Subtle Anti-Android bias strikes again. Reply

    I don't know about bias (I like to attribute ignorance over malice) but it seems particularly bad that not only is the N7 zoomed in compared to the Mini, but it's zoomed in so much that the N7's image is larger than the Mini's.

    I can see zooming so that they're physically the same size (but then the N7 would be using more pixels to render the same thing) but it's not even at that level.

    because Anand's bias is showing.

    Still waiting for this rumored 'Anandtech' windows 8 review. But OMG look a small ipad, the site owner himself reviews.

    Might as well start renaming the website 'appletech'

    Our Win8 performance guide will be done this week. We're not doing a massive review (that would mostly be rehashing our significant DevPrev and ConPrev articles) will hit all the high points.

    And note that what Anand does has no bearing on Win8. AnandTech is more than one person, and in this case since I'm the OS guru it's my article.

    I'm just disapponted that a site I've trusted and visted for years, is changing focus.

    if its an apple thing, there are tons of in depth reviews done right away, product, os, accessories etc etc.

    windows is now becoming the abandoned step child.

    look at this, pages of writing, that could be summed up in 2 words:

    smaller ipad.
