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.

Anand, any tests that actually test the battery life using apps? I use tablets for reading mostly and very curious to see lifespan of the Tab S with an app running constantly.Laststop311 - Wednesday, June 25, 2014 - link
I've been hoping for 10"+ oled screens for a long time. Shame they still haven't gotten the rest quite right. Lots of stuttering in simple tasks that shouldn't be there. Is there no micro usb 3.0? If there is no micro usb 3.0 ok but if there is really bad to go with 2. It delivers less power and is slower. The cases are utterly terrible. No 64 or 128GB internal memory options is not so good, i mean at least offer us 64GB. 16GB shouldn't even be an option it should be 399 for 32GB and 499 for 32GB 450/550 for 64GB 550/650 for 128GB.I'm actually ok with the plastic as it's the lightest most durable option and just makes the most sense. Kinda stupid to sacrifice weight and durability just for a more premium look or feel. The exynos chip is once again another let down. The LTE version with a snapdragon 800 will probably run a lot better maybe even better battery life wifi mode vs wifi mode. Disappointing that it will be released so close to the snapdragon 805 making its first commercial appearance. The 2560x1600 resolution would of greatly benefitted from the new GPU and i feel like current gpu tech on mobile soc's was only meant for 1920x1200 maximum. I think the reason samsung didn't bother with that option is the snapdragon 805 doesnt have an integrated lte modem which was samsungs main reason for using a snapdragon in the lte model. So there was no reason to wait and the snapdragon 810 is too far off.
I think these high res tablets are slightly ahead of their time. But it's good they are coming out as it motivates the gpu makers to provide large performance increases to accommodate the new resolutions and still be able to push games graphically.
I think the Galaxy tab s2 will reveal what this new tablet line is truly capable of. A 64 bit snapdragon 810 in the LTE model. Playing all games even graphically intense ones at native resolution smoothly. Wireless charging should be added to the next version too. I see a very bright future for this new S line of tablets and I think they will be sticking around for a long time. I can see the future bringing a 4k oled screen to the line in 2 or 3 years. Can't wait to see what samsung does with bigger oled screens. Would love to see the 12.2" one go to oled as well.

I recently got a Tab Pro 10.1 and after knowing of these new AMOLED tablets I was kinda regretting it. After looking at the browsing battery life results, I have to say that's not the case anymore. Samsung weren't kidding when they said they built these things primarily to watch videos.Aqua1ung - Wednesday, June 25, 2014 - link
It's basically the 16:10 format that's killing these tablets for me. I don't buy a tablet to (primarily) watch movies on it, and I don't know anybody who does.spectrablue - Wednesday, June 25, 2014 - link
how about you start browsing the web in a black background white text power saver format instead of the traditional color settings?spectrablue - Wednesday, June 25, 2014 - link
or even better yet green text...sound familiar?Fidelator - Wednesday, June 25, 2014 - link
What are the scores for the galaxy tab pro 8.4 on the graphic tests?Fidelator - Wednesday, June 25, 2014 - link
And this outdated Exynos shouldn't be used in devices on this price range this far into this year, they could have chosen the same K1 as the Xiaomi tab or the 801/805 depending on availability, going cheap isn't going to get a single dollar from me, I'll see what is released alongside Android L and then I'll chose whether to wait for broadwell or buy something in this league.iPads aren't bad tablets but I need to access the file system without having to go through hell for that

I'm just learning this stuff and am changing my 1st Gen. iPad. I love my iPad but thinking about switching to the Samsung Tab S; can you use a thumb drive with it? Advice PLEASE!marytattoo - Sunday, June 29, 2014 - link
you can use a micro sd card in samsung devices. not sure, but this one will probably take a 128 g.
