That's Opera Mobile, the mobile browser in pre-smartphone era. The desktop version is a different product that works just like any other browser. It used to be the "fastest", like chrome is "fast" today, but I believe it has been surpassed by Chrome in this regard.
EDIT: Someone else also pointed this. Apologies for multiple posting.
No. Opera Turbo was and is still a very desktop feature, and it does significantly speeds the browsing experience. They have moved this convenience/feature over to their mobile offerings.
Opera Mini is the pre-smartphone browser (Very good IMO)
Opera Mobile is their Android offering (Very good IMO)
