Surface 2 and Nokia Lumia 2520 are the only Windows RT tablets will be available in the near future. Even though both these devices runs on ARM processors, there is a huge difference between both of them as Surface 2 is powered by Nvidia Tegra 4 processor while Lumia 2520 is powered by Qualcomm Snapdragon 800 processor. Speaking to CNET, Qualcomm executives emphasized the better overall performance of Snapdragon 800 powering Lumia 2520 over Surface 2. They went on to state that it’s not even comparable!
“The performance on [the 2520] is brilliant,” Raj Talluri, senior vice president of product management for Qualcomm’s application processors, told CNET. “It’s really at the next level. It’s not even really a contest [compared to Surface 2] … In every area, it’s much bigger, faster, and lower power.”
We are yet to see the actual performance and battery life reviews of Lumia 2520 against the Surface 2 before drawing conclusions about both these ARM processors.
