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 it’s released later this summer.
The new processors don’t have a hard launch date yet, but will be launched later this summer. Therefore, this is more of a performance preview than a review, but it will show you what to expect should you purchase one at launch. Before we move on, here is a table to better help you understand the entire Conroe line-up, including these new offerings. Just bear in mind that once this refreshed line-up hits the market, some other models may be phased out.

Note that all listed with an * denotes that it is one of the new processors slated for release this summer. The QX6850 is tentatively priced for $999, the E6850 for $266, E6750 for $183 and the E6550 for $163. Upon launch, the other part of line-up is expected to go down in price. If proven true, the Q6600 is expected to be priced identically to the E6850 at launch.
As mentioned in the intro, the new releases retain the same TDP as the previous releases. When the CPU voltage was set to “Auto”, the actual voltage used was 1.344v. The CPU is able to run with less voltage, and we will tackle that more in our overclocking section.
E6750 – Stock speed of 2.66GHz

Most of the 1333FSB reviews you see around the web today will be of the E6750 for the fact that it is likely to be the most desired pick of the new line-up. The E6850 costs about $80 more for a 340MHz boost, something that can be accomplished with this CPU without even increasing the voltage. However, for CPU overclocks of 4.0GHz and higher, the E6850 will be the preferred chip for the 9x multiplier. The E6750 has a 6 – 8 multiplier, meaning that your motherboard will need to handle a 500FSB to hit 4.0GHz… a tough task.
We’ve covered all the basics, so let’s compare this new CPU to our E6600 and Q6600 processors on hand.
