Overview

This video shows a comparison of two identical prototype phones with NVIDIA Tegra APX2500 processors. The phone on the left is running the Windows CE kernel, the same OS kernel used in Windows Phone 7. The phone on the left is running the Windows NT kernel, the same OS kernel used in Windows Phone 8. Dubbed “Experiment 19”, the prototype system on the right proved that the Windows NT system could achieve better performance than Windows CE on identical hardware. The system was first demonstrated at MSR TechFest 2009. Filmed in 2009, this demonstration proved for the first time that Microsoft could use the same core windows components for both PCs and phones. On June 20, 2012, nearly 3 years after this video was recorded, Microsoft publicly announced that Windows Phone 8 would use the same Windows core as Windows 8.
