Tablets with the highest pixel density

Huawei MediaPad X1 - 323ppi
Though it could technically be used as a phone, Huawei's MediaPad X1 still classifies as a tablet. Its 7" display sports a resolution of 1200 x 1920 pixels, which delivers an acceptable pixel density of 323ppi. What's even more interesting is that the display itself occupies roughly 80% of the front panel. This makes the compact Huawei a noteworthy slate, which could easily stand up to larger rivals sharpness-wise. The rest of the Mediapad X1 are pretty decent, too - we are dealing with a quad-core, 1.6GHz Hisilicon Kirin 910, 2GB of RAM, a 13MP rear snapper, and a 5,000mAh battery.
Xiaomi MiPad - 324ppi
In a pre-Nexus 9 era, Xiaomi's MiPad was the first tablet to make use of Nvidia's Tegra K1 chipset and its 192-core Kepler GPU, which provide some pretty serious processing vigor. The 7.9-inch display of the tablet has a resolution of 1536 x 2048 pixels, which puts it on par with the so-called Retina display of the Apple iPad mini 2 and the Apple iPad mini 3. A 6,500mAh battery, 2GB of RAM, and a 8MP rear camera are also aboard the specs sheet of Xiaomi's tablet.
Apple iPad mini 3 - 324ppi
The newest compact slate from Cupertino bears is hardly an upgrade over the previous Apple iPad mini 2, as it's extremely easy to point out the the few new features - apart from the support from Apple Pay and the new gold color option, hardly anything has changed. This means that the Apple iPad mini 3 comes with a 7.9-inch display with a resolution of 2048 x 1536 pixels, working out a pixel density of 324ppi. This is roughly the same as the iPhone 6, which comes with a 326ppi-dense display.
Unveiled roughly a month and a half ago, Amazon's latest offering to the tablet market sports an 8.9-inch display with a resolution of 2560 x 1600 pixels. Hence, it's display is among the most pixel-rich out there - 339ppi are nothing to write home about on a phone, but in the world of tablets such a sharpness goes a long way. The slate has some nice hardware insides, too - it's the first tablet in the world to feature a Snapdragon 805 chipset.
It's not out on the shelves yet, but the 6mm-razor-thin Dell Venue 8 7000 will boast an 8.4" OLED display with a resolution of 1600 x 2560 pixels, working out a pixel density of 359ppi. The rest of its specs are nothing to be ashamed of, as this Android-powered Dell Venue dons a quad-core Intel Atom Z3500, paired with 2GB of RAM, and interestingly enough, 3 cameras at the rear - an 8MP main one and two RealSense depth-sensing ones.
This is it, the Samsung Galaxy Tab S 8.4 is the tablet that has the most pixel-dense Super AMOLED display and you can actually buy. At 8.4 inches and with a resolution of 1600 x 2560 pixels, this blown-up Galaxy S5-lookalike sports an extremely high (for a tablet, that is) pixel density of 359ppi, making it the king of tablet world. This throne is being shared with yet another Samsung device, the Galaxy Tab Pro 8.4, which also has an LCD display with 359ppi in tow. What's next?
