The HTC Desire 820 is powered by 64 bit Snapdragon 615 quad core chipset with 8 cortex A53 cores divided in two clusters, running at 1.5 GHz and 1 GHz. The chipset is aided by 2 GB RAM and 16 GB internal storage which can be further expanded by another 128 GB. The HTC Desire 820q employs 64 bit Snapdragon 410 quad core processor with all cortex A53 cores clocked at 1.2 GHz. This will be an upgrade over 32 bit Snapdragon 400 which is quite common these days. The RAM capacity is 1 GB and the 16 GB native storage can be further expanded by 128 GB.
The HTC Desire 816G on the other hand, employs the low cost MT6582 1.3 GHz quad core chipset with 1 GB RAM and 8 GB internal storage, expandable by another 32 GB. All three phones have a 5.5 Inch SLCD 2 Display with 720p HD resolution similar to Desire 816, but the Desire 816g won’t have Gorilla Glass 3 protection unlike its other 2 siblings. The primary camera module also remains same. All three phones have a 13 MP rear camera with BSI sensor, f2.2 wide aperture, 28mm lens capable of 1080p Video recording. The Desire 820 and 820q flaunt an 8 MP BSI front camera also capable of 1080p video recording, while the Desire 816g is sticking to 5 MP front snapper in its predecessor. Other hardware similarity include front facing dual Boomsound speakers, dual SIM functionality, Android 4.4.4 Kitkat with HTC Sense 6 UI and 2600 mAh battery. While the Desire 820 and 820q will support 4G LTE, The Desire 816g will feature only 3G connectivity. Overall the refreshed HTC Desire 816 lineup seems interesting with different models to keep the price in check and also to keep it relevant. The Desire 816g will be available for 18,990 INR starting early October (Desire 816 is selling for 21K approx) while The Desire 820 and 820q will arrive later in November.
