HTC 8X review: Windows Phone 8's compact flagship -- Engadget
The 8X's Super LCD 2 display crams 1,280 x 720 pixels into a 4.3-inch diagonal -- that's 341ppi of HD goodness, if you're keeping track. It's also optically laminated to the glass surface for more sharpness and less reflections. All this results in a gorgeous screen with inky blacks and natural colors that's bright enough to handle direct sunlight. Strangely, the viewing angles don't quite match what we've experienced with the One X, despite both phones sharing the same panel technology. We're being picky here, to be sure, and most people will be hard-pressed to notice a difference.
Spec-wise, the 8X features a 1.5GHz dual-core Qualcomm Snapdragon S4 SoC paired with 1GB of RAM. This is a huge improvement over Windows Phone 7 devices which are limited to a single core processor and 512MB of RAM. As we pointed out above, there's 16GB of internal flash with no way to add more -- while Windows Phone 8 supports microSD storage, HTC chose to do without. Our global review unit includes quad-band radios for both GSM / GPRS / EDGE and UMTS / HSPA+ (the latter compatible with 2100, 1900, 900 and 850MHz), but some upcoming models (like AT&T's) will also provide LTE functionality. Additional radios include 802.11a/b/g/n (dual-band), Bluetooth 2.1 + EDR, A-GPS and NFC. Finally, you'll find the usual collection of sensors on board: proximity, ambient light, compass, accelerometer and gyroscope.
