difference between Pentium D and Core 2 Duo

[hermeslyre]

X2 and Core2 Duo are rivals, but not the same...not really sure about performance characteristics of either. X2s are cheaper, but - best to my knowledge - generally underperform similarly clocked c2ds in most applications.

If I'm wrong, gimme some real evidence to chew up!

X2's are about 30% less efficient that core 2 duo's, clock for clock, according to the benchmarks I've gandered at. Shorter pipes, higher IPC, a generally superior core architecture.

Well, whoever made the analogy first, kudos, They're both very easy for non-computer folks to understand.

They're underperforming powerhogs that only outperform bar heaters. However, they still lag behind more powerful Central Heating systems that...

Not looking to start anything, but my D 940 is Idling at 31*C right now. Lower performance than a C2D, but relatively cool if you know what you're doing.

What kinda cooling r'ya using? And what kinda temps d'ya get under heavy loads?

Just curious. Not looking to start anything, either.

A $10 (after $10 MIR) Masscool HSF: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2943299&CatId=1588 (It was originally $20 before; Newegg has the same one for a bit cheaper). At full-throttle, I see 43-45*C. If I crank the house heat up to 74*F, I still only see 33*C at Idle. My house temp is 70*F normally.

yeah truth is i believe that they are only that hot because of their clock, if you were to use a C2D at the same clock i'd bet that they have around the same temperature, mine is clocked to 2.9ghz right now and it's at 32C

Is Intel Pentium Dual-Core EXXXX(any of 4 numbers) Allendale work just like Core 2 Duo right? but Intel Pentium Dual-Core using 1 MB each. They made this Intel Pentium Dual Core soo cheap even The new [email protected] will come out in this March for $93.99 http://www.onsale.com/shop/detail.aspx?dpno=7398114&store=onsale&source=bwbfroogle

Yes, Pentium Dual-Core & C2D are practically the same, pentiums come with less cache and are underclocked. Pentium Dual-Core is a good processor - they're higly overclockable and most of the time only significantly underperform similarly clocked C2D's in heavy multimedia applications and such because of their smaller cache.

EDIT:
Actually I'm not sure if Pentium Dual-Cores are based on Core2 or the older Core architecture...either way, what I just said still holds true.

Pentium Dualies are based on the Core2 Conroe arch.

Yeah, Overclocker's dream chip, very inexpensive, very overclockable.
