I see that E6850 and E8400 are both rated as 3.0 GHz. E6850 costs more and it has 4 MB L2 cache. E8400, on the other hand, costs less but it has 6 MB L2 cache.

Besides L2 cache, what are the real differences between these 2 CPU? Why would E6850 cost more but with less L2 cache?
 
65nm vs 45nm build process.

The E8400 is the newer chip, thus it is priced less. This is standard for intel now. If you look you'll still find E6600 cost more than the E6750, in fact they tend to cost more than the E8400.

Is there any lot number I should look for in E8400, like G0 for Q6600?
 
Ghz for Ghz, the E8400 @ 3.0 will bench faster than an E6850 @ 3.0.
 
Yes, very important to get a mobo that supports 45nm, depending on the revision and bios version loaded, it may or may not need a bios flash. I set up my current build with an E6850 but I did flash it to the latest bios when I bought my E8400 a month ago. I did see a performance gain at stock clocks with the E8400, but the main benefit is in the overclocking ability of the two cpu's.
My fastest oc for the E6850 was 3700 MHz, but that required a lot of juice, about 1.525v and was not Orthos stable. With the E8400, I am at 4005MHz at 1.344v Orthos stable, and I could go higher.
I paid about 325 bucks for the E6850 a few months ago vs $220 for the E8400, quite a diference in price:cool:
