Face Off: Samsung Galaxy Tab S 8.4 vs. Sony Xperia Z3 Tablet Compact vs. Dell Venue 8 7000

Best 8-inch Android tablet? Android tablets have flooded the market from manufacturers big and small. We help narrow down your choices in the competitive 8-inch category to the three best currently available. Which one comes out on top?

Apple's iPad has been slowly losing market share to Android tablets as inexpensive and premium alternatives flood the market. It's not hard to see why when dozens of popular Android tablets are available for less than the retail prices of new iPads or iPad Minis.

On that note, Android tablets don't get much sleeker or thinner than these three for this week's Face Off. The Galaxy Tab S 8.4, Xperia Z3 Tablet Compact, and Venue 8 7000 are some of the best 8-inch Android tablets currently in the market. We'll compare and contrast some of their respective core features to see which can come out ahead. If you had to buy just one, which would it be?

We encourage users to check out our dedicated review pages below for more data and detailed analyses of each of the three models. This comparison is by no means a replacement, but a condensed aid for those on the fence.

Case

Starting with Samsung, the Galaxy Tab S 8.4 utilizes a largely plastic chassis designed to give the impression of metal as is typical of the Galaxy family. Nonetheless, the case proves to be robust with no hints of gaps or manufacturing defects. Attempting to twist the case or apply pressure on the center do result in some creaking during our time with the test unit.

Sony's Xperia tablet is better built with its combination of stainless steel corners, tempered glass front, and plastic and aluminum back. The reinforced edges and corners allow the tablet to be airtight against both dust and water under certain conditions. Twisting and warping the frame is still possible with moderate to heavy force that would otherwise be abnormal during everyday use.

The Dell Venue 8 7000 holds the strongest chassis out of the three. Its machined aluminum is very difficult to twist or deform in comparison. The tablet is more rigid than its super-thin form factor would otherwise suggest at first glance.

In terms of size, these 8-inch tablets are essentially neck-to-neck and literally a couple of millimeters apart at most or even less when comparing thickness. If we're being picky, the Dell tablet is the thinnest while the Sony tablet is both 30 grams lighter than either tablet and with the smallest footprint (L x W).

The Venue 8 7000 wins this round based on construction quality and longevity. Users who are more likely to expose their tablets to coffee spills or splashing water may prefer the Sony solution.

Winner: Dell Venue 8 7000

Connectivity

Physical ports are identical between the models save for the docking port on the Sony tablet. There are unfortunately no HDMI ports on any of the tablets, so users will have to rely on WiDi or MHL-enabled monitors for video output.

The Xperia tablet is the only one with NFC while the Venue tablet is the only one lacking SIM support. Sony takes this round by just a hair over the Samsung followed by the more limited Dell tablet.

Cameras

Both the Galaxy Tab S 8.4 and Xperia Z3 models have good rear cameras considering the form factor. The Samsung tablet is the only one with an LED Flash and may be the better option for darker indoor shots. Otherwise, picture quality is sharp and a bit overexposed in our experience. In comparison, pictures taken with the Sony camera tend to have a blue overcast with paler colors in general.

The RealSense technology on the Dell is a major selling point for the Venue 8 7000. Its 3D capabilities allow for image refocusing, depth and height measurements, and other unique editing features that are wholly dependent on the stereoscopic 720p cameras of the tablet. Look past this indubitably fun novelty, however, and you'll find an average 8 MP camera. Details are lacking, images are not as sharp, and color noise is more prevalent. Quality is a few steps down compared to the Samsung and Sony.

If based on camera quality alone, the Galaxy Tab S 8.4 comes out just slightly ahead of the Xperia Z3 and even further ahead of the Venue 8 7000. If users are looking for the higher fun factor, however, then the Dell tablet takes the cake.

Input Devices & Controls

The 10-point capacitive screens and virtual keyboards on all models respond swiftly to inputs. None, however, have integrated styluses a la the Nvidia Shield Tablet.

The Samsung tablet is the only model with dedicated Android buttons (Home, Back, Tabs) near the bottom surface, which free up valuable screen real-estate for applications and content. Its home button is also a fingerprint scanner for fast unlocking.

Sony's tablet features metal Power and Volume buttons. Its virtual keyboard includes options to split the keys for easier use in landscape mode. Otherwise, the Xperia Z3 provides no other unique inputs. Oddly enough, there are no proprietary official keyboards that make use of the docking port even though Sony sells a charging station and PS4 controller adapter specifically for the tablet.

The narrow bezel of the Venue 8 7000 makes touch-typing a bit more difficult due to accidental inputs around the edges. Thus, more care must be taken when holding the device in the Landscape orientation. The tablet offers no haptic feedback either. Dell is pushing its USB-enabled Cast dongle to wirelessly connect to external displays, keyboards, and mice. While a neat extra, the same can be accomplished with Bluetooth-enabled accessories and Miracast-compatible displays.

Since no single model is any better or worse at basic keyboard inputs, we are down to choosing the one with more auxiliary features. The Galaxy Tab S 8.4 wins this round mainly for including haptic feedback, which is sorely missing in many other premium tablets.

Display

Make no mistake -- these tablets offer superb displays. Compared to other Android tablets in the market, you really can't go wrong with choosing one of these three if based on screen quality.

Which display is the best overall? If color accuracy is priority, then the Samsung tablet is the better choice. Its AMOLED panel is famous for its ability to be pitch black and the manufacturer advertises 100 percent sRGB coverage as well, which is a feature that not even most notebooks can claim. The over-saturated colors of older AMOLED panels are no longer an issue here.

Sony relies on the tried-and-true IPS panel combined with its signature Triluminos technology for a wider spectrum of colors than normal. Its screen is exceptionally bright at over twice that of the Samsung and Dell tablets at the cost of having reduced resolution, poorer grayscale, and both lower contrast and color accuracy in comparison.

The OLED panel on the Dell is exceptional on its own and provides a contrast level as deep as the Galaxy Tab S 8.4. Unfortunately, neither color accuracy nor brightness are as good as the Samsung and Sony, respectively.

Users who will mainly use their tablets indoors may prefer the Samsung model. For outdoor use, however, the Sony tablet comes out ahead by far. The powerful backlight is simply invaluable even if that means small sacrifices to color quality that are largely insignificant for everyday use.

Performance

CPU Performance

Three high-end processors from three different manufacturers duke it out to be crowned the fastest CPU. Results from multiple benchmarks, however, show no single processor reliably outranking the others by wide margins. Subjective performance is silky smooth on all occasions.

Perhaps more noteworthy is the fast read and write rates of the Venue 8 7000. This will have a more real-world effect as opposed to any raw CPU performance differences between them. The Dell tablet comes out ahead consistently on many browser-based benchmarks such as Google Octane, Sunspider, Mozilla Kraken, and WebXprt 2013.

See our dedicated CPU pages on the Exynos 5420 Octa, Snapdragon 801 MSM8974, and Atom Z3580 for more comparisons and benchmarks.

GPU Performance

While CPU differences are mostly marginal, a handful of graphics benchmarks show some notable differences. Unfortunately, the results are not always consistent with one another.

The Sony tablet scores highest in Epic Citadel, BaseMark X 1.1, GFXBench 3.0, and the Anomaly 2 benchmark in high quality. It's worth noting that the PowerVR GPU in the Sony only has to power a 1200p screen as opposed to the 2K screens on the Samsung and Dell. The pixel count is nearly double that of the Sony, so GPU demand on the Xperia Z3 Tablet is lower. The resolution differences make direct comparisons difficult through benchmarks.

Meanwhile, 3DMark results favor the Dell tablet likely due to other factors beyond GPU power. 

Subjectively, we faced no issues playing 3D titles from the Play market with a few exceptions. For example, the high native resolution of 2560 x 1600 can be a bit much for more demanding 3D titles like Anomaly 2 or Asphalt 8. These games stutter more frequently on the Samsung and Dell tablets when running on High settings compared to Medium or Low.

More benchmarks and technical data on the ARM Mali-T628 MP6, Qualcomm Adreno 330, and PowerVR G6430 can be found on our dedicated GPU pages.

Temperature

Idling temperatures are generally flat on both sides of the three tablets. However, surface temperatures are indeed warmer on the Sony with a recorded high of 41 C when under extreme processing load. This is perhaps unsurprising given the fact that the Snapdragon 800 series is notorious for its high heat output. The Samsung tablet suffers from a hot spot on the back surface as well, though not as severely as the Sony.

Dell comes out ahead with a flatter temperature gradient even when under high processing loads. The tablet barely reaches the mid 30 C range compared to ~40 C on the Samsung or Sony.

Winner: Dell Venue 8 7000

Battery Life

Runtimes are very long in all cases. The Galaxy Tab and Venue 8 7000 can last for over 8 hours each according to our older WiFi test. Sony comes out ahead for its potential to last for 14 hours under the same conditions. The Japanese manufacturer advertises 15 hours of continuous video playback, which is not far from the truth.

Verdict

The Venue 8 7000 is great but lacking in features. The Galaxy Tab S 8.4 and Xperia Z3 tablets are more well-rounded for indoor and outdoor use, respectively.
The Venue 8 7000 is great but lacking in features. The Galaxy Tab S 8.4 and Xperia Z3 tablets are more well-rounded for indoor and outdoor use, respectively.

Starting off with the Venue 8 7000, Dell is putting most of its advertising efforts on the thin and sleek form factor and RealSense cameras. These are two of the best features about the tablet that make it stand out from the crowd. Look beyond them, however, and the Dell tablet will feel very barebones in features and connectivity despite its excellent first impression. The Dell is lacking SIM, NFC, docking port, LED Flash, and a good rear camera compared to the Samsung and Sony. If any of these additional features are priority for your next tablet, then the Venue 8 7000 is a pass. We feel that these extras may have been omitted in favor of the super-thin thickness and stereoscopic cameras.

On the opposite end of the spectrum is the Galaxy Tab S 8.4, which is loaded with features including haptic feedback, IR, and a fingerprint scanner. Colors and contrast are more accurate here, especially compared to the contrast on the Sony tablet. Its plastic chassis is still weaker than on both the Sony and Dell and its display brightness could have been brighter.

All three tablets are very close in terms of performance and size and no one model is a bad buy. Indoor users may want to consider the Samsung for its extra features and higher resolution while outdoor users may prefer the Sony for its incredibly bright display, long battery life, and stronger water-resistant chassis.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
