Performance

The WiFi only variants of the Galaxy Tab S all feature Samsung’s own Exynos 5 Octa (5420). Internally we’re dealing with four ARM Cortex A15s and four ARM Cortex A7s in a big.LITTLE configuration, with a maximum of four cores of the same type being active at any given moment. The Cortex A7 cluster can run at up to 1.3GHz while the Cortex A15 cluster maxes out at 1.9GHz.

CPU performance is reasonable but definitely behind Apple’s Cyclone cores in A7 and even Intel’s value Bay Trail offerings that are cropping up in tablets like ASUS’ Memo Pad 7. The problem with the latter is that those devices end up being substantially cheaper what Samsung is asking for with the Galaxy Tab S.

GPU Performance

The bigger problem really seems to be GPU performance. The Exynos 5420 integrates ARM’s Mali-T628MP6 GPU, which just isn’t competitive with Apple’s PowerVR Series 6 implementations. The bigger problem is that the GPU doesn’t seem quite cut out to driving the high resolution display. UI frame rates are typically smooth but I definitely noticed some dropped frames. The device is by no means unusable, I’m just spoiled by how good everything is at the high end of mobile that even mild deviations are noticeable.

Internal NAND Storage Performance

Storage performance is pretty solid. Both read and write performance are good given what we’re seeing from most players today. I’d always like more but there’s not a ton to complain about here.

    And all will still continue to be gimped with the usual 16GB of internal storage (with 8.5GB available left to the user). It's 2014, not 2011. It's time 32GB became standard across the board no matter what. Also, I wouldn't pay these kinds of prices without having microUSB 3.0 connectivity (I am spoiled by my Note 3) AND wireless charging (to save the aforementioned port from overuse). I'm also slightly miffed by the use of an Exynos instead of a Snapdragon. Now, if they refresh these guys this fall with the latest version of Android, an 801/805, add USB 3.0 from the Tap/Note Pros AND double up the storage while holding the line on the the price then I might consider it!

    What does it matter how much storage is on board? For a Nexus 7 or an IPad it matters but Micro SD cards are dirt cheap... I picked up a 128GB for $110 for my Tab Pro. That is a grand total of 144 GB of storage(less OS and Apps) for just over $500. Compared to $800 for a Mini Retina with 128GB that's almost $300 cheaper. As mentioned the USB 3.0 is too thick to fit into this tablet. I have several devices that I have been charging and using for literally years without any overuse of the micro USB port so why worrry?

    Google got rid of saving to apps to SD cards, so it does matter to those that use large HD optimized apps Reply

    Especially with all the bloatware Samsung puts in it... There will be like 8-9 gb space available for apps. Not good enough Samsung. Not for a $500 device. Reply

    10.5GB available for a $400 device, lol. And remember all the bloatware Google Corporation requires, including but not limited to a social network, a chat app, an extra browser, their ad network, a gaming center, and llittle stores and proprietary apps for music, expensive movies, and even magazines.
    At least Samsung adds things like multi-window, grayscale mode for battery savings, 1% battery.

    Samsung Galaxy Tab S seems to be a choice, although I personally prefer getting one of the top models from Samsung (see http://www.consumertop.com/best-tablets/ for example), but that's just me. Some people might like this! Reply

    I want to see what the they can do with an 808 or 810 that will be using a die shrink. That is what I am interested in for both phones and tablets. They really should be pushing these chips to be released by years end, not early next year. Oh well. Reply
