Anand has since corrected his numbers, the Transistor count is 1.16 billion for SB v/s 1.4 billion for IB, which is about 20% more. Most of these would be towards the GPU but there are some improvements to the CPU cores as well (probably a Conroe to Wolfdale type change). Number of EU's remain the same(16) so the performance increase is only due to arch improvements and higher clocks (say 20%). Overall Vantage score increases by about 60% according to Anand, and 3DMark 06 by about 30%.

And anyway, HD5870 brought a ~50-60% performance increase over Hd4890. I would hardly classify that as "not much"

Well most of the transistors would be for the GPU. Apart from DX11 they are also beefing up the media capabilities (three displays, faster quicksync, etc). While the CPU side is also going to be improved somewhat, it isnt anything like the changes to the GPU (you could say CPU is a tick and GPU is a tick+)

Edit: Also with regard to Trinity, it looks like we could be heading towards an early 2012 launch, so it might beat Ivy Bridge!
