When Bearlake launched last month, it opened the doors for native 1333FSB processor support. That's where the refreshed Conroe line-up comes into play. In our performance preview of the E6750, we will show you what to expect when its released later this summer.

Beyond the increase in FSB speed, there really isn't too much more to know about the E6750, other than the fact that the chip is based on a new stepping and revision of the Conroe core and that it will require a motherboard and chipset capable of supporting the new 1333MHz FSB.

We received from Intel a Core 2 Duo E6750 engineering sample, which is basically a Core 2 Duo E6700 with a 1,333 MHz FSB instead of 1,066 MHz. It will be launched later this summer together with several other Core 2 Duo models with the new 1,333 MHz FSB, and from the naming used on E6750.

The new P35 and upcoming X38 chipsets from Intel are capable of supporting front-side bus speeds of 1333MHz, and Intel plans to introduce a slew of Core 2 processors primed for the faster bus. Although those CPUs won't officially debut until later this summer, we have a preview today of one of those chips, the Core 2 Duo E6750.
