The latest Pi version is a quad core arm A53 running at 1.2gig so considerably faster than the original Pi model. They also support neon in the latest models so that if you can take advantage of it give you a massive speed improvement.
There's a thread on the Raspberry Pi forums that has a lot of linpack style testing done on it which might be worth a look if you're interested.
