iPad mini Review
by Anand Lal Shimpi & Vivek Gowri on November 20, 2012 6:10 PM ESTCPU Performance
As I mentioned before, the bulk of the innovation in the iPad mini is around form factor - the hardware platform itself is mostly a reuse of previous designs to keep costs low. The mini retains the 32nm A5r2 SoC as the iPad 2,4 and 5th gen iPod Touch. Despite the smaller size, it also uses the same 1GHz CPU clocks as its bigger brother. Performance is thus identical to the iPad 2,4, and a bit faster than the iPhone 4S. I found that the increase in clock speed does help to mask the fact that this isn't a Swift based platform, although going between the iPad mini and 4 does reveal an appreciable performance difference.
We're still very limited in good, cross-platform CPU benchmarks. We, once again, turn to JavaScript tests run in the browser. For all of the tablets tested here we're using Chrome for Android and Mobile Safari for iOS.
SunSpider has been a part of all of our mobile performance testing for quite a while now. It's not the perfect benchmark, but the test ends up being a good measure of browser performance as well as cache latency and CPU performance.
The iPad mini's two Cortex A9 cores running at 1GHz give it performance that is pretty much identical to the iPad 2 and 3, which also feature the same CPU. In the grand scheme of things however, the mini's performance is decidedly last generation. That's not to say that it's bad, it's just that the Swift based architecture in the A6/A6X is significantly better.
Google's Octane benchmark is a much larger test than SunSpider, but we're still looking at JavaScript performance. Octane includes all 8 of the tests from Google's older V8 benchmark but adds 5 new ones including a PDF reader, 3D bullet physics engine and portable 3D game console emulator all built in javascript.
Here the mini shows its age a bit, but mostly because of its conservative CPU clock speeds. Google's Nexus 10 is finally able to flex its muscle here and show just what the Cortex A15 is made of, even outperforming Intel's Atom in the RAZR i. Also note the performance increase compared to the iPhone 4S/iPod Touch, that's purely due to the clock speed advantage (1GHz vs 800MHz). I don't believe Apple picked the wrong clocks for the A5 in the mini as battery life remains a primary concern for this device.
Finally we have Kraken, a seriously heavy javascript benchmark built by Mozilla. Kraken focuses on forward looking applications that are potentially too slow to run in modern browsers today. The result is much longer run times than anything we've seen thus far, and a very CPU heavy benchmark:
Once again the mini equals the performance of the iPad 2 and 3, but remains appreciably slower than the iPad 4/iPhone 5. Google's Nexus 10 absolutely dominates in this test, continuing to outperform Intel's Atom based RAZR i.

Am I the only person who thinks Anand is just another Apple shill who just falls over himself supporting any and every Apple product out there? Please. What ever happened to the objectivity that once was the hallmark of Anandtech? I've watched the same thing happen to Tom's Hardware over the years. I guess it must be the koolaid they drink.uhuznaa - Wednesday, November 21, 2012 - link
Well, maybe this *is* objective and what you want to read is something subjective that starts and ends with "everything Apple is crap"?This review points out all the weak points of the device, comes with a lot of objective numbers and benchmarks -- what do you miss exactly?

I really don't think it's necessary to make personal insults against the staff. Yes anand clearly likes apple. But look around. So does half the continent.edsib1 - Wednesday, November 21, 2012 - link
You state that the mini display is great but, in your own tests...Pixel density - 5th of 7
brightness -13th of 17
contrast - 17th of 17
calibration - 6th of 7
grayscrale - 3rd of 7
saturation - 4th of 7
GMB - 6th of 7
I dont understand your conclusion. Doesnt add up to a great display to me.

The answer is two-fold.FIrst, the tests were against other rather good screens. So coming in "average" is actually quite good. Here's the key statement, near the end of the review, "It pains me to say it, but compared to most similarly priced notebooks, the iPad mini's display is amazing."
Second, often times the margin of difference must not have seemed significant to Anand. For example, if two screens are 1% apart on a particular metric (pulling a number from nowhere) then which came in 1st vs 2nd is a relatively meaningless.

i personally dont get it. i have an ipod touch, iphone and ipad and pretty much never use the ipod or ipad. the ipad is only good for checking an email quickly or looking at a youtube video. anything beyond that and its frustrating to use. personally i would rather have a laptop/ultrabook. not sure i understand making the mini other than just to have a cheaper "i" product to complete with kindles and androids. i didnt think apple was about going cheap.Jumangi - Wednesday, November 21, 2012 - link
I can't see how any tech enthusiast site could look at the Mini and be impressed at the overall product. A 1 1/2 year old SoC. A screen resolution that goes back even farther and skimping out at 512MB or RAM. Any other manufacturer tried to pull that off would get slammed on all points but because the Mini has a nice case well all is good I guess...drx11 - Sunday, November 25, 2012 - link

You can not see it, because it is in the software... the SoC the apps, etc... you miss the forest for the trees. You miss the computer (system or tablet) for the specifications of the various parts...

Hi Anand thanks for the article.I was wondering if you had any plans to review the new B&N Nook HD 7" tablet? It would be interesting to read your findings on it's higher resolution screen. Also any plans for a tablet round up pre-xmas, as they are a nice size/price for potential presents? It seems the choice comes down to Nexus 7 vs N&B Nook/Kindle fire HD or the mini Ipad for iOS.

"I don’t consider the iPad mini a competitor to the Nexus 7"What the heck? I jsut do not understand the continuous worshipping of this company's garbage products. It is almost like people dont even actually use these things. In reality, ther eis no difference between this and something like a nexus 7. They're both going to be extremely limited, extremely frustrating devices. iPoopa are anything but buttery smooth flawlessly running devices these biased reviewers make them out to be. I can make my iPoop crash just by opening webpages. Every time I'm scrolling thru the app store it lage like hell. The thing is really unbearably slow in jsut about everything. I only have about 100 apps installed. (58 of which want to update right now, but hell if I'm gonna bother.) I hate this thing. I only use it as a remote control nowadays. Even that crashes. It's really terrible. I refuse to believe that it is something unique to my device. What's more liekly to me is that the people who never have any problems with these things are the people who never actually use them.
