We get some interesting scaling factors for Core logic and L2 sram:

 
 Logic Area Scaling 130-->90  = 0.72 instead of the ideal 0.48   =(90/130)^2 
 Logic Area Scaling  90-->65  = 0.70 instead of the ideal 0.52   =(65/90)^2 
 Logic Area Scaling  65-->45  = 0.75 instead of the ideal 0.48   =(45/65)^2 
  
 SRAM  Area Scaling 130-->90  = 0.67 instead of the ideal 0.48   =(90/130)^2 
 SRAM  Area Scaling  90-->65  = 0.64 instead of the ideal 0.52   =(65/90)^2 
 SRAM  Area Scaling  65-->45  = 0.52 instead of the ideal 0.48   =(45/65)^2

1)The logic scaling from 90->65 is exactly the same as for AMD.

2)The Sram scaling for 65->45 is either extremely good or I am
to optimistic about the 115 mm2 die size for Penryn. (They
achieved the same sram scaling in the sram test devices so it's
probably very close.

3)The Core area's of Merom and Penryn seem exact copies if you
place one over the other and make it transparent.
