Upgradable processing speed on the lenovo yoga pro 2?

I was told from a different source this product

http://www.amazon.com/...00GUNZUG0/

would improve my Wi-Fi connectivity, blu tooth, etc. The one part i was skeptical about is that the source stated it would bring my processing speed up to 5ghz rather than the 2.6ghz that is standard on the computer. Is this claim accurate. I couldn't determine from the specs on amazon whether this was true. If not, what would be a more effective solution to upgrade my processing speed if possible?

This would not make your processor faster. It would just be a little faster Wi-Fi connection and have bluetooth.
