Earlier today, at MWC 2014 in Barcelona, Qualcomm introduced three new additions to the Snapdragon family. First up, the Snapdragon 801 (SM8974AC), which is basically a beefed up Snapdragon 800 chipset. The core clock has been bumped up to 2.45 GHz (from 2.26 GHz), GPU clock to 578 MHz (from 450 MHz) and memory bus to 933 MHz (from 800 MHz). Also, the chip supports eMMC 5.0, a new standard that allows for faster flash storage.
  Second, we have the Snapdragon 610, which is a 64-bit quad-core chip based on ARM Cortex A53 cores coupled with the Adreno 405 GPU. And lastly, the Snapdragon 615, which is a 64-bit octa-core chip also based on Cortex A53. It's not a true octa-core design, unlike MediaTek's MT6592. Rather, it consists of two quad-core clusters.
  While S801 based devices are slated to arrive by next month itself (Sony Xperia Z2), the first devices based on the new Snapdragon 600 series chips are expected to arrive in Q4 2014. All chips are based on the tried and tested 28nm LP process.
