For a while, Qualcomm had an exclusivity deal with Microsoft for Windows on ARM, but that deal is about to expire.
Vole has told chipmakers that anyone will be allowed to build a Windows on ARM chip, and they are rushing to do that.
Last week we saw MediaTek is planning to build a chipset for Windows on ARM, and others are expected to follow.
Samsung is expected to throw its hat into the ring with its Exynos processors, especially given its recent partnership with AMD for graphics power.
