it hasn't been a full year since we saw Intel launch their Core 2 Duo processors, but we will soon be seeing a line-up refresh. This is one product that really needs no introduction, but seeing as this is a refresh, refreshing everyones minds seems appropriate. Intel launched the Core 2 Duo to much fanfare last July. Months prior to this, enthusiasts were drooling over leaks of performance reports, which fortunately, turned out to be right on the money.

The entire Conroe line-up is built on a 65nm process, with the mainstream products offering 4MB of L2 cache. Improved over the previous Pentium 4/Pentium D line-up was better power efficiency resulting in a lower TDP and better overall temperatures. This is appreciated, as two cores under the same IHS can potentially create an unwanted room heater.

All but the lowest end Core 2 Duos take advantage of a 1066FSB. This is where this refreshed line-up comes into play, as it ushers in 1333FSB computing. This noticeable speed bump is all done while retaining the same TDP.

All Conroe 1333FSB processors are identified by by a 50 at the end of the product name, hence E6750, which is effectively taking over the spot of the E6700. Nothing has changed except for the FSB and speeds, except the ratio of course, which had to be altered in order to compliment the upgraded frequency.

One thing that should be cleared up is that most overclocking enthusiasts have already accomplished the same speeds we are seeing today, with most being exceeded. In fact, there is nothing stopping anyone from popping in an E6600 and overclocking using a 333FSB and 8 multiplier. That would effectively give you the exact same speed as the E6750 we are taking a look at today.

You might be wondering where the benefit is, with this official speed bump. Primarily it will benefit those non-overclockers most. There is no comparison to equal processor speed at 1066FSB and 1333FSB. That added FSB frequency should make a much more noticeable performance difference than the CPU frequency boost itself.
