Pentium d 930 is a superior chip.First of all it has 4mb cache compared to the 2mb of 8xx and it is manufactured in 65nm compared to 8xx's 90nm.If i were you i'd buy the pd 930 but i'd wait a little longer because with the release of core 2 the pd 9xx will have a major drop in price.......
930 of course. The 840 is still expensive because it's at high demand while the 930 is way lower and have way better performance-to-cost ratio over 840. The 930 also runs cooler and can overclock a bit higher than the 840 due to its more better 65nm structure. I have the 840 and it cost me $550 when I bought it the day it came out and performance wise I have overclocked it to 4Ghz and anything over that is unstable, that is on water cooling. The 930 otherwise can overclocked more than the 840 in terms of percentage.
So the for the price and performance the 930 is much better. :wink:
The 840 has a thermal design of 130 watts operating between 1.2 to 1.4 volts
The 930 has a thermal design of 95 watts operating between 1.2 to 1.375 volts making the D930 the more efficient CPU.
Both processors have a 15X multiplier and over clock very well.
The 930 being 65nm runs at much cooler temps and will be friendlier with a higher fsb .
The stock hsf will be sufficient for small oc’s.
As stated above.
There is no comparison between the two.
The D930 is the higher quality processor.
If your not an over clocker you may opt for the D940 at 3.2 GHz (prices are dropping)
Just if you don't know, Conroe is a new intel chip that is coming out end of July and will fit in a LGA775 socket.
The ASUS P5WD2-E Premium is based on the intel 975 chipset which will support conroe but only with later revsions. It can be hit and miss getting the later revision for the board that will support conroe so you might want to stay away from it.
The P5B Deluxe is based on the newer intel 965 chipset and will definately support conroe. This board would be the one to pick if you want to ensure future upgradeability. Both boards are good though and you shouldn't be worried if you pick either.
I will have to say the 930, much cooler.
The 800 was such a joke, too hot too slow and you paid $500 to go from 840 to 840EE which only had HT, what a joke
All prescott are the shame of Intel and will mark the company forever
