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.

    "Contrast is the single-most important part of subjective (ie: what peoples eyes say) display quality - according to every study ever done on it - and AMOLED displays have infinite contrast. Not sure why it wasn't tested here, but the ludicrous contrast makes this screen many-times superior to the iPad screen, IMO."
    A) contrast is NOT the single most important, subjective performance standard. Brightness and saturation. IE, 'Torch Mode!' That's why every TV at best buy is cranked to vivid, 100% pic and high saturation levels. NOT blacks and shadows. It's important to me, but as you've answered your own question, it's impossible to measure 'infinite contrast'. As OLED displays don't 'turn on' a pixel on black scenes, it's 'truly infinite' and hence impossible to measure. Though I'd argue if it's such a subjective and deciding quality, why aren't we using OLED displays to 'produce, color, and finalize' a motion picture? While DisplayMate's results do indeed separate these tablets, the overall scores are a point apart. Not leagues. I own the Note 3 and iPad Air as well as the retina mini and 5s. They're all phenomenal displays and excellent systems. To argue ones better than the other is like arguing pancakes vs waffles. They're both light years ahead of my Magnavox 13 channel (manual) 13" black and white I had in high school with rabbit ears ...or my first 16 'color' display after a decade in monochrome. LoL, kids these days ;)

    think again...
    "Based on our extensive Lab tests and measurements, the Galaxy Tab S is the Best Performing Tablet Display that we have ever tested, not surprisingly with performance that is almost identical to the OLED Galaxy S5 Smartphone that we recently tested and found to be the Best Performing Smartphone Display"..."Comparisons with the Amazon Kindle Fire HDX and Apple iPad Tablet Displays: In 2013 the Amazon Kindle Fire HDX Tablets became the top performing Tablet displays in our Display Technology Shoot-Out series, leapfrogging the competition with cutting edge displays using Quantum Dots and Low Temperature Poly Silicon. But with the ever continuing and impressive improvements in display technology the Samsung Galaxy Tab S has now taken the lead for the Best Tablet Displays. The Apple iPad Air, which came in second after the Kindle Fire HDX 8.9, now moves into third place for Flagship Tablet models, and the iPad mini with Retina Display, with a very disappointing 63 percent of the standard sRGB/Rec.709 Color Gamut and poor Color Accuracy moves further down the pack for the Mini Tablet models.

    Does it contain the usual Samsung "crapware" or is this already a more "standard" Android device, like a Nexus?
    Linked to the above, does it receive Android updates immediately when they are released by Google or does it still take years before they get updated? (and how long will they be updated after release?)
  • GC2:CS - Tuesday, June 24, 2014 - link

    How long ? About 18 months since release, eg until end of 2015. Reply
  • apandya27 - Tuesday, June 24, 2014 - link

    Updates will definitely be delayed. 5-6 months is usual for *new* devices. That goes up to 8+ months for older devices. Reply

    That video playback battery life!!!! If I am getting a new tablet(pretty happy with my Nexus 7 2013) the Tab S would certainly be my pick, Touchwiz be damned. Reply

    Touchwiz gives you easy access to many settings, as well as the multi-app multitasking capability, and better camera UI than most. I wonder why everyone hates touchwiz so much. Reply

    Ok.... Anand did you noticed how much free memory these tabs got ?!? Reply
  • sherlockwing - Tuesday, June 24, 2014 - link

    If it didn't take up 4Gb of internal storage for 1000 functions that I don't need & ancient UI elements(gingerbread era) eyesores I'd have a little less problem with Touchwiz. The better Camera UI thing is now irrelevant with the free Google Camera app, and I get to many key settings much faster on AOSP than I do on Touchwiz. Reply
