We start off with Snapdragon 835, which is a 64-bit mobile processor developed by Qualcomm. It can be found in the smartphone HTC U11. This is the first Qualcomm chip manufactured through a 10nm technological process. Snapdragon 835 features eight Qualcomm Kryo cores – the first four reach a clock speed of up to 2.45GHz while the second four – up to 1.9GHz. Moreover, the chip offers a 25% increase in the graphics performance, 35% or 3 hours more video playback, 30% or 8 hours more listening to music and 43% or 3.5 hours more web browsing compared to its predecessor Snapdragon 820. The specs sheet is complemented by the support of up to 4K displays, up to 32MP camera or up to 16MP dual camera, NFC, Bluetooth 5.0, LTE Cat 16 connectivity which provides download speed of up to 1Gbps and upload speed of up to 150Mbps, as well as Quick Charge 4 technology for faster charging. Here, the Adreno 540 GPU takes care of the graphics performance.
