From Ars Technica:
Intel's transition to the 90nm fabrication process was tough. The move to 65nm looks to be shaping up a lot better, as the CPU giant will reportedly introduce the desktop Conroe process in July 2006, several months ahead of schedule. Conroe will make its appearance at the same time as the upcoming 965-series chipset to create an all-new desktop platform for Intel systems.
2006 looks like it might be the year where Intel bounces back fully from hitting the wall with the Pentium 4 architecture, and finally regains some of the performance ground it has lost to AMD over the last couple of years. While the server side of things still needs some work, Intel looks to be in great shape on the desktop and in the laptop once Conroe and Merom are shipping.
