Windows Phone 7 Series Minimum Hardware Requirements
Microsoft revealed the minimum hardware requirements for Windows Phone 7 Series devices at the MIX conference, shown below. Nothing too surprising here- we’re looking at some pretty high-end specs. WP7 does not support external memory cards, so the phones must have 8GB or more built-in flash storage.
The specs list “ARMv7 Cortex/Scorpion or better” for the processors, referring to ARM Cortex A8 processors (used in the iPhone 3GS and other high-end phones) and Qualcomm’s Scorpion core from its Snapdragon chipsets (found in the HTC HD2, Google Nexus One, and others). We’re told there are more specific performance requirements, though. For more information on mobile processors, see our Smartphone Processor Guide.
