WiFi

Both Galaxy Tab S devices support 2-stream 802.11ac and can negotiate up to an 866Mbps link speed with a similarly capable router. Peak performance in practice is pretty shy of what we saw with the Galaxy S5 however. While the GS5 was capable of around 430Mbps under best conditions, the Tab S averages around 240Mbps. Compared to the immediate competition it’s not bad, but against everything else we’ve seen it’s less impressive.

Camera

Samsung only gave us a few days with the review samples so I didn’t spend a ton of time focusing on camera performance. The rear facing camera is a 8MP design with F2.4 lens. The front facing camera shoots at 1080p and also has an F2.4 lens. In general the Tab S seems to be a decent shooter in well lit conditions. Low light performance isn’t the worst I’ve seen but it’s not a strong point for sure. Both tablets appear to use the same rear and front camera (Samsung S5K6B2) modules.

    If you don't like sunspider for whatever reason, look at one of the other values. No-one is forcing you to base your opinions on one number.
    But for many of us sun spider most accurately captures the snappiness of a browser in real use, which is something we care about. Kraken and Octane are too much biased towards JS performance and multithreaded JS. That's fine if that's what you're interested in, but it's silly to pretend that that's a better measure of how the device feels in normal use.

    lilo777's comment seems to be an important one. Perhaps a generalist tech site like Anandtech isn't the most knowledgeable about testing screens. How were the tests conducted? Perhaps the method that was used to display an image on the screen was sub-optimal. For example, an image normally has a profile associated with it and some programs will use that profile in order to determine the correct way of displaying that image - eg whether sRGB or Adobe RGB colour spaces are appropriate.

    There seems to be an important discrepancy here.

    still wondering about the overall value and performance of the s 8.4 and the pro 8.4 ?????

    You are obviously uninformed. If you do not understand why an OLED display is a more pleasant experience, then it really cannot be explained to you.

    It has better contrast, better white point, better grayscale accuracy, gamut and saturation accuracy are so close to the Air display you won't be able to tell without measuring equipment. I'd say it is a match to the Air display and significantly better than anything else. It's pretty great, considering Samsung don't have fanatical devotees to exploit and must sell much more balanced products at lower profit margins.

    The display in the samsung tablet has better contrast, a wider gamut, better resolution and a much faster response than the display in the ipad Air.

    Sasmung makes display panels for both ipads and Galaxy tablets, so it is only natural that Samsung would reserve the superior panel for their own tablets.

    That's assuming Apple is willing to compromise on their display's?

    Sorry to burst your bubble but Apple compromises on many things to preserve their profit margins... See eg skimpy RAM that means that webpage tabs always face to reload when you switch between them, causing info to be lost... Low RAM also caused the iPad Airs and minis with retina to crash and freeze frequently. The one I bought for my sister froze all the time - a $500 product at that! Similar issue with their highway robbery pricing for storage... $500 device with only 16 GB and no micro SD is an insult and a ripoff. (That goes for all brands but we are starting to see some change... More companies bundling 32 GB into the base model).

    Another example would be the (again insulting) ugly TN panel in the MacBook Air - $1000+ computer with a low rez TN display. Only Apple could get away with it.

    The display in the Sammy is nine months newer than the Air/Mini and 5s. Those products are coming down the pipe in the next quarter. How about we compare current to current versions enforced deciding? And with those results, it's pretty apparent Apple's 2013 design was pretty damn good and holding it's own almost a year later (keep in mind it's dominance at release in comparison to AMOLED tablets). Hold your reservations. The Air's display is beyond outstanding and if the Sammy is this good, neither is 'bad' nor will the majority be able to discern any difference at these resolutions

    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.

    That said, there are plenty of folks that (for some reason) prefer LCD to AMOLED, so who am I to judge.
