Apple stole a march on Android when it released the iPhone 5S with a 64-bit processor, and Android manufacturers have put the pedal to the metal in a race to catch up and make their products 64-bit. AnandTech reports that HTC has announced the Desire 510, its first 64-bit Android phone.
Meanwhile, AnandTech describe the device in more detail:
While normally one might expect high end phones to get the latest and greatest features first, this time we see a bit of a surprising reversal. The Desire 510 is HTC's first 64-bit phone, and the first announced device with Snapdragon 410. For those that aren't familiar with Snapdragon 410, it has four Cortex A53 CPU cores running at 1.2 GHz, along with an Adreno 306 GPU which suggests that it is a mild modification of the current Adreno 305 GPU that we see in the Snapdragon 400. Overall, this should make for a quite fast SoC compared to Snapdragon 400, as Anand has covered in the Snapdragon 410 launch announcement.
While it may seem strange that ARMv8 on Android phones is first to appear on a budget smartphone, it's quite easy to understand how this happened. Looking at Qualcomm's roadmap, the Snapdragon 810/MSM8994 is the first high-end SoC that will ship with ARMv8, and is built on a 20nm process. As 20nm from both Samsung and TSMC have just begun appearing in shipping chips, the process yield and production capacity isn't nearly as mature as 28nm LP, which is old news by now.
Other details include:
- SoC: MSM8916 1.2 GHz Snapdragon 410
- RAM/NAND: 1 GB RAM, 8GB NAND + microSD
- Display: 4.7” FWVGA (854x480)
- Network: 2G / 3G / 4G LTE (Qualcomm MDM9x25 UE Category 4 LTE)
- Dimensions: 139.9 x 69.8 x 9.99mm
- Weight: 158 grams
- Camera: 5MP rear camera, .3MP/VGA FFC
- Battery: 2100 mAh (7.98 Whr)
- OS: Android 4.4 with Sense 6
- Connectivity: 802.11b/g/n + BT 4.0, USB2.0, GPS/GNSS, DLNA
- SIM Size: MicroSIM

64-bit ARM has twice the number of GP and FP registers [32 each vs 16 each for 32-bit Cortex ARM cpus].
Apple claims that just recompiling for 64-bit ARM [at least for their chip] gives around a 30% speedup for cpu-dependent code vs the same 32-bit code on an iPhone 5S and other's have checked and confirmed it [of course it is approximate and depends on the specific code].
