Based on the 45nm Nehalem architecture, Intel aims to bring Bloomfield clock speed above 4GHz in 2008. It is a speed that Intel never get to hit with their previous generation of processors where the highest clock speed reach is 3.8GHz with their Pentium 4 570 & 670. Bloomfield will contain 8MB of shared L2 cache which is smaller overall in comparison to Yorkfield 2x6MB L2 cache. As we have previously reported, Bloomfield is Socket B based, quad core and is capable of 8 threads. It is still within the 130W thermal envelope.
