Intel’s Dunnington: Six cores on one chip
Posted February 26th, 2008 by Andrew PopoffDunnington would be Intel’s first monolithic design since its original Core 2 Duo chips released in 2006. The presentation indicates that Dunnington has six 45-nanometer Penryn-class cores integrated onto a single die.

That’s a ton of space to store frequently used instructions, which could be a help for the chip in avoiding the front-side bus bottleneck to the main memory that’s still apparently in the works for Dunnington.
