Microsoft is testing a Windows Phone 8 handset with a dual-core 1.5GHz Qualcomm MSM8960 chipset for Sprint’s network, The Verge reported on Wednesday. Qualcomm’s Snapdragon S4 processor has posted impressive performance when powering Android devices, beating out Samsung’s Galaxy S II (Exynos) and Motorola’s Droid 4 (TI OMAP) by a wide margin in many tests. Microsoft hopes the chip will bring similar performance to the Windows Phone platform. Sprint has reportedly shared its LTE specifications with Nokia and may not introduce any further Windows Phone devices until Windows Phone 8 is launched later this year, The Verge claims.
