In December, as part of the last Patch Tuesday of 2013, Microsoft rolled out new firmware update for Surface Pro 2, which stuck with problems and the software maker had taken down the package.

Several affected users had asked for the replacement of its Surface Pro 2, and after replacement, few of them discovered that the new tablet was equipped with a different processor.

Instead of Intel Core i5-4200U 1.6 GHz (2.6 GHz with Turbo Boost), Microsoft equipped a Core i5-4300U 1.9GHz (2.9GHz with Turbo Boost) processor. In addition to the slight increase in clock speed, the processor supports several advanced technologies for safety, which were absent in the original model, on sale from October 22, 2013.


Although, the GPU remains the same (Intel HD Graphics 4400), but the clock frequency is higher (1 GHz versus 1.1 GHz). Compared to the predecessor, the new CPU supports six additional technologies — typically reserved for business notebooks – that are: Intel vPro Technology, Intel Virtualization Technology for Directed I/O (VT-d), Intel TSX-NI, Intel Stable Image Platform Program (SIPP), Intel Small Business Advantage, Intel Smart Response Technology and Trusted Execution Technology.

All these technologies improve system security, performance, multi-threaded and performance of solid-state drives.

“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,” A Microsoft spokesman confirmed the change in a statement,

Despite the Redmond’s statement, it’s not clear why they replaced the processor. Probably the lack of autonomy reported by some users was due to a defect of the old CPU or Intel has completed the inventory of the Core i5-4200U and gave Microsoft the new model at the same price. In the coming days, we may see the new firmware removed in December from Windows Update.
