Desktops forum: Pentium 4 or Pentium D

Dual Core is amazing. Do it.

"The P4 has higher clock speed, but the Pentium D has....."

What amazes me, is now that Intel has to admit that there is more to a processor ablity than what can be advertised in MHz or GHz (clock speed,) how engrained the clock speed syndrome has become in the human psyche.

Go with the D. There is really no comparison. also when you want to and can afford it most of your parts will be Core DUO ready.

I have found that My 905-D @ 2.66 ghz smokes my P-4 3.2 EE @ 3.2 ghz. And it NEVER crashes

I have the equivqlent Dell and I would update in a heart beat. FSB(Memory needs to match) L2 Cache!

I have several computers that I maintain. My main computer is still powered by a P4 at 3.2 But I am in the process of upgrading to Core Duo 2.66. I also have a couple of Pentium D. Simply put the Pentium D gives you the most computing power for the buck. The Core Duo is faster but will cost more. Here are some raw numbers. You be the judge.
Definitions: FP= Floating point operations performed by the CPU per second. Mops = Million operation per second.

Core Duo at 2.66 FP = 2,497 Mops
Core Duo at 2.13 FP = 1,955 Mops
Pentium D at 2.8 FP = 1,397 Mops
Pentium 4 at 3.2 FP = 1,373 Mops

The floating point speed is the actual number to calculations that the process is performing per second. But remember that a computer is like a chain. It is only as fast as it's weakest link. You might have fast processor but other componet can slow the computer down. However, if you are talking only about which processor is fastes, look at the mops.

I actually went with the P4 simply because I don't really do a lot of multitasking. I don't see myself doing lots of video editing or playing Half-Life 2 while buring a CD and printing a photo. Plus I heard the dual-core's have a tendency to over heat. The actual difference in speed between the two looks marginal to me. My PC should be here in a couple weeks.

can the pentium D(which tobe honest I never new they did as a Dual Core...But hey) go on a PCI motherboard that originally had a pentium4(4socket LGA775 CPU)3.06ghz???

yep def 775 with a 1gig cashe, ill try and find out what motherboard i Have as all software help on this issue just ives me numbers with the bios software being 'Award',also im running a ITA pci x1300 super pro graphic card with 512 on board and i have 3 of my 4 memory slots full with half gig ddr2 memory cards as my sysytem is ddr2 compliant

or MB mfgs website.

MB mfg and revision.

Look in your system manual or your MB manual, might find the info on the WEB, look at the MB or download and run manual CPUZ . . . report info found under 'Mainboard' tab. Even iof its a clone...it'll tell you what MBs in the system.

Without the specific info ... you're just getting logical guesses and those don't always work. Don't know about you but I don't want to go thru the hassle of buying something that may not work and I'll have to return and pay restocking. Your call.

Yes, I should have read the post properly. The board is a socket 775, however the 3.06 GHz processor has a 533 MHz FSB(Check http://processorfinder.intel.com/List.aspx?ProcFam=483&sSpec=&OrdCode= ).

Yes, your processor does have HT technology, but you need to make sure that it is enabled in the BIOS, your chipset is HT enabled and that you run a up to date version of Windows XP (or Linux) as this will benefit you the most. Ht is not Dual core, but a processor that allows 2 threads to pass through a single core, sharing its internal structure. Therefore will you not get the same performance as a Dual core Pentium D or even better the Core 2 Duo.

The Pentium D805 is the only one to have a 533 Mhz FSB, but even so you must check that the motherboard (Chipset) is compatable. All other Pentium D has a FSB of 800 MHz exept 1066 MHz for the extreme edition D955 and D965.

ok my pentium4 of 3.06G with 1G cashe,,,it is only 533mhz, and goin off the intel site no other pentium 4 is higher than 533mhz, Its a ddr2 system with PCI graphics-this being an ATI radeon x1300 PRO super(super being because procards came standard with 256 on board memory,super was the boosted 512mb memory/again ddr2 and crossfire ready/I have 200gig sata hd and an external 100gig(sony).System memory is 1.5 gigs(3 half gig cards in 3 of the four memory exp ports) originally it had half a gig memory and a ATI radeon x300(128 mg on board)and all slots are PCI (forgot to mention the motherboard has also on board intergrated Radeon X-press200 graphic chipset- this i have disabled),although the graphic card is also AGP 8X compatible also by a slide of a switch, now when i run decent games i find that i need to stick a pedastal fan near my computer, you see when u turn mine on the fan goes through its test going full speed which is very noisey then it slows after about 3 seconds and the noise disapates, but lately its started goin really high for a sec or two then drop again and continue doin this randomly while playin games yet not in windows, yet the fan dosnt have any in between if you know what i mean(build up to the fast) it dosnt seem right, so the pedestal fan near the grill stops this(i do live in australia and it is mid summer at moment, ive been told it sounds like just a build of dust over it, the heat sink, and the sensor making the sensor report wrong. any one have any clues to this-definately not as bad as the burnin cpu but hey-i could be next,Oh and i have checked in my bios and it is still getting a temp reading/computer set to turn off at 90/warn me at 80 and it runs about 65-75, but just finishing there is no inbetween from the fan bein average to really fast when it does it??? any idea"s???

Excellent info, sasquatchll!

For those who are interested, here is a list of Intel CPU's. Lots of Pentium 4 models with 800MHz FSB:
http://indigo.intel.com/compare_cpu/default.aspx?familyID=1&culture=en-US

It is my understanding that it is possible to have dual channel mode with 3 RAM modules according to the Intel specification. Example: two 256MB modules in Channel A can pair with one 512MB module in Channel B.

Pentium D would be best. Pentium D is dual core.

It is really an upgrade.
