In the demonstration, the same CPU was cooled by thermal paste and the thermal sheet side-by-side, with the paste keeping the processor at a steady 53 degrees Celsius. The sheet achieved a slightly better 50 degrees Celsius. The actual CPU used in the demonstration wasn’t identified.
Sony wants to get the thermal sheet used in servers and for projection units, but I can definitely see this being an option for typical PC builds, too. It's certainly going to be less messy and probably a lot cheaper than buying a tube of thermal paste."
