Apple, Amazon, Google And More

Arm beat expectations in its first post-IPO earnings report Wednesday. Its low-power chip architecture is in nearly every smartphone, replaced Intel’s x86 processors in Apple’s Mac computers, and is the basis for Qualcomm’s PC processors, and Amazon’s data center chips. CNBC went to Arm in Cambridge, England, to find out how it became the year’s biggest IPO despite 20% of revenue coming from China, struggling smartphone sales, and a failed $40 billion acquisition attempt by Nvidia.
