Qualcomm has leaped ahead of Apple in 64-bit mobile chip development with its first eight-core Snapdragon 615 chip for mobile devices, which has integrated LTE and 4K video rendering capabilities. The Snapdragon 615 will go into high-end smartphones and tablets, which should become available in the fourth quarter, a Qualcomm spokesman said in an email. High-end smartphones are typically priced above US$500.
