Microsoft'shas been given a processor upgrade only two months after its release.
The processor in the tablet has received a speed bump with an upgrade from a 1.6GHz Intel Core i5 4200U CPU to a 1.9GHz Core i5 4300U chip.
"Microsoft routinely makes small changes to internal components over the lifetime of a product, based on numerous factors including supply chain partnerships, availability, and value for our customers," Microsoft said in a statement.
The Surface Pro 2 earned praise for improving the performance in Internet Explorer and 3D graphics over the original Microsoft Surface Pro when it was reviewed last year.
The Pro 2 contains the U variant of the fourth generation Intel Core CPU, which offers better performance than the more power-efficient Y-series of Intel Core processors.
ZDNet sister site CNET captured the screenshot below showing the 300MHz speed bump.
The news of the upgrade was first reported by Windows rumours site WinBeta.
