The first performance previews of the upcoming Intel Intel Core 2 Duo E6750 CPU have surfaced.

Hothardware writes "The E6750 differs from the older and similarly clocked E6700 in that its front side bus frequency has been increased to 1333MHz, but this isn’t a simple speed bump. The E6750 is also based on a new stepping and revision of the Conroe-core which resulted in some excellent overclocking. How does almost 4GHz with the stock air-cooler sound?" Techgage writes: "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."
