In November 2007, Intel started to replace their 65nm based processors with the “Penryn” family based on 45nm production technology. The quad-core Q6000 (Kentsfield) is being replaced with Q9000 (Yorkfield) and the dual-core E6000 (Conroe) with E8000 (Wolfdale). We reviewed the first 45nm quad-core product, the QX9650, when it was launched in November 2007. Since the end of January 2008 dual-core products based on 45n production technology are available as well: the E8500, E8400 and E8200 clocked at 3.16 GHz, 3.00 GHz and 2.66 GHz respectively. Additional models, such as a lower priced E8190 without virtualization technology, will follow in Q2 2008. All new products come at least with 1333 MHz front-side bus frequency. For some time Intel will continue producing 65nm dual-core products with a system bus frequency of 800 MHz. This is the E4000 series with 2 MB L2 cache and the E2000 series with 1 MB L2 cache. Eventually the entire processor line-up for server, desktop, and mobile usage will be moved to 45nm Penryn parts.
