The minimum specs for Microsoft's Windows Phone 7 OS have taken a nice bump upwards, it has been revealed at this year's MIX . Current WP7 handsets are all running the Qualcomm MSM8x50 Snapdragon, the original 1GHz chip with Adreno 200 graphics, but Microsoft has now upgraded the requirement to Qualcomm's second-gen part, the MSM8x55 and the more powerful Adreno 205 GPU. That's already seen widespread adoption among devices like the HTC Thunderbolt and Xperia Play , but Microsoft isn't content with just one option and is also throwing in Qualcomm's MSM7x30 , a fine multimedia performer that's already hit the market inside the T-Mobile G2 . The latter part also comes with Adreno 205, making it a constant of future Windows Phone devices, while the option to include a gyroscope has also been provisioned for. Video of the MIX 11 session explaining these tweaks and much more about WP7 architecture can be found after the break.
