The new Core 2 Duo E7200 is the first member of the "Wolfdale-3M" family. You may remember that not so long ago we looked at the new Wolfdale family of 45nm processors, which consists of the E8200, E8300, E8400 and E8500 processors. These still remain today as the fastest Core 2 Duo processors, offering superior performance and efficiency not to mention stellar overclocking abilities.
The Wolfdale-3M family is, as you may have guessed, a cut-down version, and as the name alludes to, these processors feature a smaller 3MB L2 cache and a 1066MHz FSB. With the Core 2 Duo E7200, Intel is offering a 45nm processor that is considerably more affordable than the cheapest Wolfdale (~$180), and even undercuts other budget oriented models such as the E6550 that roughly costs $160, while the E4700 is also more expensive at around $140.
