P4 630 vs 930 performance single core

[JWade]

My wife's system has a 630 in it, been thinking of getting her a 930 or even a 940 as prices have dropped alot onthem. Now on the 930 each core has its own 2mb cache as the 630 has the 2mb cache for its single core.

I know the 630 and the 930 have different cores, the 930 is Presler. Is the performance between the two of them the same since they have the same cache size and same speed? I know that apps that benefit from dual core, the 930 will be best, but i am also concerned about the single core performance. If they are the same/or very close to the same i will get her one because of the benefits if she does any multi-core tasks.

Yes for single threaded tasks the Pentium D 930 would basically be exactly the same as Pentium 4 630 as they have the same clockspeed, FSB and cache amount.

I have a 660, an 840, and a 950. I was running the 660 in my everyday pc and was very happy with it, the 840 and 950 were being swapped around in my benching setup. I recently stuck the 840 in the everyday pc and am amazed at the difference in the system, even doing mundane everyday playing around it just feels so much quicker. The 950 is by far the fastest of the bunch and it will soon replace the 840 when I get a good Conroe board for benching. The only concern is cooling, the 9** series run much hotter than the 6** series, they are even harder to cool than the 8**'s. If you can cool it, and at stock speeds it should be easy enought to do, then by all means get the 930

thanks boshuter, for the most part you have convinced me to go with the 930 or the 940. The system is a dell system and has a heatpipe heatsink for it, so i am thinking the cooling should be good.

Man, I don't agree with that statement at all. I had a 640 in my 975 board for a few weeks before I got my 930. The 930 runs cooler then the 640 did with both running stock or both running a 250 fsb. I never see temps higher then the mid 40s under full load dual priming.

I don't agree either, my 920's run much much much cooler than my 805 and 830. Heck, at 3.6ghz on the stock heatsink my 920 runs cooler than my 830 did at stock speeds.

Ok... I won't argue with you... or Intels thermal specs. To be honest I've never checked temps at stock speeds. My everyday pc is water cooled and I've never ran the cpu's in the benching system at stock speed.

I can tell you, and anyone else that overclocks will tell you the same thing. the 9** series are the hottest running cpu's by far than anything else produced by Intel. My single stage phase change will not even hold sub zero temps on the 950 at anything above 5.3ghz or so, at 5.5ghz it will barely keep it cold enough to run 1M SuperPi. The same single stage will hold -25c on the 660 at well over 5ghz and do the same for the 840 at 5ghz.

So maybe you should listen to those guys, I'm basing my statements on overclocked cpus and they are running basicly stock speeds.

I still say "get the 930"... they are fast

I'm not doing the exotic overclocking you are, but I have overclocked all of my CPU's. At 3.6ghz on the stock heastink, neither of my 920's got over 55c. My 805 was hitting about 68c at stock speeds on the same heatsink, and my 830 was hitting 74c and throttling at stock speeds on the stock heatsink. My 805 is hitting 57c on water at 3.7ghz..and any one else that I have seen with overclocked 9xx series chips all run much cooler than the 8xx series..but none of them were using phase and going to 5ghz either..

That's nice and all your basing your comments on 5GHZ overclocks for your themral comments but is that relevant for this wifes system? IS he going to be overclocking to such levels at all?

Here are some facts.
and pentium 4 6xx series aren't cedar mill chips.Those are prescotts.The cedar mill ones have the name 6x1.
The pentium d 8xx series are buy far thehottest and the most power hungry.Thepentium d 805 is the overclocking king.
Dual core has a lot of benefits and will be essential very soon.
