Clock speeds are expected to start at 1.6GHz and top 2.2GHz. Like current generation Turion chips, the new processors will offer 64-bit software support and are expected to feature 2MB of L2 cache. The launch comes late as Intel's Core Duo hit the market a while back and products with the Core-Duo platform have been out for a while. Funnily enough, Intel has done to AMD what was done to it in the desktop segment where AMD launched ahead of Intel with 64-bit software support, dual-core processors and low costs.
Keep in mind that Intel is also late. It will take until summer (or even september) for Intel to bring Merom into the market. Their current Pentium-M and Core Solo/Duo chips have no 64bit. All they added was SSE3, and AMD's dual-core implementation appears to be far more efficient than intel's.
