The Apple iPad 2 Review

We’ve had a few requests to double check and see whether the iPad’s original camera connection kit works, and sure enough it still does. We put together a simple yet representative benchmark comparing how fast it took an iPad 1 and iPad 2 to import 40 NEF (Nikon RAW, lossless compression enabled) photos shot using a Nikon D300s.
The iPad 2 bests the iPad 1 by a considerable margin at import speed, it's 47 percent faster. Subjectively, initial image previews also rendered much, much quicker on the iPad 2.
I always felt like speed was honestly what kept me from using the camera connection kit more than once in a blue moon on the original iPad, coupled with the relatively limited 16 GB of storage on the WiFi model I opted for. Though this time around I still went with 16 GB, it’s now fast enough to import a substantial number of photos even from the most competent of cameras very quickly.
The other gems that are enabled by the USB Host port bundled with the camera connector kit also still work. You can still connect a keyboard and use it as an input device wherever text fields are, mice still don’t work (not a huge surprise there), and 16-bit USB audio class devices work.
I connected my Logitech USB headset and microphone combo to the iPad through the camera connector kit. Audio played back through the headsets from all applications. In apps that use recording, the microphone also worked.
The interesting caveat is that you apparently can’t use both at the same time, at least not this pair. I fired up FaceTime in the hopes that I’d be able to use the headsets in their entirety - callers could hear me through the microphone (and noted I sounded excellent), however audio played back through the iPad’s internal speaker instead of the headphones. I connected through a powered hub and experienced the same thing. There are anecdotal accounts that other devices which support simultaneous audio input and output do work, but I lack more hardware to test with. Additionally, I can’t test whether devices with higher power budgets (like the Blue Yeti microphone for example) work.
There’s definitely potential for the iPad 2 to be a shockingly competent mobile podcasting platform, especially coupled with some built-in Garage Band editing.
You can already record audio through a USB source natively in Garage Band with the camera connector kit. We tested it and it sounds excellent.

Considering the source (ARMflix), you need to take that video with a huge grain of salt. It looks like they're running some Linux variant on the two systems (maybe Chromium?), and while the build may be the same, that doesn't mean it's optimized equally well for Atom vs. A9.Single-core Atom at 1.6GHz vs. dual-core A9 at 500MHz surfing the web is fine and all, but when we discuss Atom being faster than A9 we're talking about raw performance potential. A properly optimized web browser and OS experience with high-speed Internet should be good on just about any modern platform. Throw in some video playback as well, give us something more than a script of web pages in a browser, etc.
Now, none of this means ARM's A9 is bad, but to show that it's as fast as Atom when browsing some web pages is potentially meaningless. What we really need to know is what one platform can do well that the other can't handle properly. Where does A9 fall flat? Where does Atom stumble?
For me, right now, Atom sucks at anything video related. Sorry, but YouTube and Hulu are pretty important tools for me. That also means iOS has some concerns, as it doesn't support Flash at all, and there are enough places where Flash is still used that it creates issues. Luckily, I have plenty of other devices for accessing the web. In the end, I mostly play Angry Birds on my iPod Touch while I'm waiting for someone. :-)

The article is indeed wrong to suggest that the A9 has only half the performance of an Atom. There are cases where a netbook with a single core Atom might be faster, for example if it runs at a much higher frequency, uses hyperthreading, and has a fast DDR3 memory system. However in terms of raw CPU performance the out-of-order A9 is significantly faster than the in-order Atom. Benchmark results such as CoreMark confirm this, a single core Atom cannot beat an A9 at the same frequency - even with hyperthreading. So it would be good to clarify that netbooks are faster because they use higher frequency CPUs and a faster memory system - as well as a larger battery...somata - Sunday, March 27, 2011 - link
CoreMark is nearly as meaningless as MIPS. Right now the best cross-platform benchmark we have is Geekbench. It uses portable, multi-threaded, native code to perform real tasks. My experience with Geekbench on the Mac/PC over the years indicates that Geekbench scores correlate pretty well to average application performance (determined by my personal suite of app benchmarks). Of course there will be outliers, but Geekbench does a pretty good job at representing typical code.Given that, the fact that a single-core 1.6GHz Atom (with HT) scores about 28% higher than the IPad's dual-core 1GHz A9s in the integer suite leaves me little doubt that the Atom, despite being in-order, has as good or better per-clock performance than the A9s.
Even the oft-maligned PowerPC G4 totally outclasses the dual A9s, with 43% better integer performance at 1.42GHz... and that's just with a single core competing against two!

Tablets do have their advantages despite what the article claims. For one thing, their battery life far out lives any Netbook or Notebook. They also run a lot cooler, unlike Notebooks and Netbooks, which you can fry an egg on. Maybe they aren't as portable as a phone, but who wants to look at the super tiny print on a phone.Tablets don't replace computers, and never will. There are nice to sit in bed with at night and browse the web or read books on, or play a simple game on. Anything that doesn't require a lot of typing.
Even a 10" tablet screen isn't real big to read text, but its MUCH easier to zoom in on text to read it with tablets. Unlike any Notebook/'Netbook, which its a huge pain to get to zoom in.

I do think the benchmarks shown here do show that there is quite an improvement over the Ipad 1, despite what many seem to claim that there isn't much of an upgrade.secretmanofagent - Sunday, March 20, 2011 - link
Anand,Appreciate the article, and appreciating that you're responding to the readers as well. All three of you said that it didn't integrate into your workflow, and I have a similar problem (which has prevented me from purchasing one). One thing I'm very curious about: What is your opinion on what would have been the Courier concept? Do you feel that is the direction that tablets should have taken, or do you think that Apple's refining as opposed to paradigming is the way to go?
VivekGowri - Sunday, March 20, 2011 - link
I still despise Microsoft for killing the Courier project. Honestly, I'd have loved to see the tablet market go that direction - a lot more focused on content creation instead of a very consumption-centric device like the iPad. A $4-500 device running that UI, an ARM processor, and OneNote syncing ability would have sold like hotcakes to students. If only...tipoo - Sunday, March 20, 2011 - link
Me too, the Courier looked amazing. They cancel that, yet go ahead with something like the Kin? Hard to imagine where their heads are at.Anand Lal Shimpi - Monday, March 21, 2011 - link
While I've seen the Courier video, and it definitely looked impressive, it's tough to say how that would've worked in practice.I feel like there are performance limitations that are at work here. Even though a pair of A9s are quick, they are by no means fast enough. I feel like as a result, evolutionary refinement is the only way to go about getting to where we need to be. Along the way Apple (and its competitors) can pick up early adopters to help fund the progress.
I'm really curious to see which company gets the gaming side of it down. Clearly that's a huge market.
Take care,
Anand

Gaming side is a good question. Apple will have an advantage there due to limited hardware specs to code to. They are a lot more like a traditional console that way vs Android which will be anything but.Are actual game controls like in the psp phone necessary?
I am also curious what additional UI tech will eventually make it to the pad space:
* Speech, although it is forever not there yet.
* 3D maybe if its not a fad (glasses free)
* Some form of the Kinect maybe to manipulate the 3d stuff and do magical kinect gestures and incantations we haven't dreamed up yet.
* Haptic as mentioned earlier in the thread.
Speech could make a pad suitable for hip bloggers like the AnandTech posse.
