One is newer than the other, one uses a smaller lithography (die size) and one has a smaller cache size onboard, one has a newer instruction set, one runs 260 mhz faster than the other.

All of these "ones" are the E7300

Core 2 Duo 6600

Core 2 Duo E6600

The E7300 has a Passmark score of 1720 vs E6600 Passmark score of 1130, so the performance difference is obvious and in favor of the E7300.

The E7300 is faster and has more advanced Core architecture (Wolfdale), making it the better performer.

However, both are inferior to any Core i3 (even first generation)

Look i think more processor speed is much better.

In case E 6600 it has 2.40 GHz speed But it has 4 M cache.

On the other hand E 7300 has 2.66 GHz and has 3 M cache.

So i think obviously the E 7300 is the better one.

There are few Dual Core processor that have speed more than 2.70 GHz.

I think it better to go with E 7500 it has 2.93 GHz speed. 3 M cache.

If you have more processor speed then low cache memory is does not matter. It will manage by the speed.

See in case your BIOS will admire an E8400/8500/8600 (3.0, three.18, 3.33). I am running Shuttle SFF stuff with a board like that. I've an E6600 in one, an E6850 in the 2nd, and an E8600 within the 3rd. All are simply exceptional. Watch out of the stepping on the E8XXX CPUs; pleasant guess is the E8600, however it'll price you over $250.

You aren't gonna see much difference unless ur running video rendering or high processing. The E6600 has 1M more cache and the E7300 is 0.33GHz faster. Its win/win so fit it to ur budget... i recomend moving to a quad or six core for real difference

your socket is lga 775

get a intel core 2 quad cpu

try find some used one as its quite old and will be cheaper

you will see 4 times the performance of e6600..................

Just grab a celeron g1610 and a h61 motherboard.
