Default which is processor is better.

I am going to be buying a computer mainly for gaming and multitasking and was wondering which processer would be better:

2.8Ghz Pentium D 820 Dual Core 1MBx2

or.....

3.4Ghz Pentium 4 HT 650 64Bit 2MB


both systems cost the same and since I really don't too much in the differences between the two any explanation would help a lot.

that aint answering his question is it though ?^^^^


i would think the pentinum D would be better cos although it is slightly slower in clcok speed it is dual core although i would wait and see if other people agree

pentium d isnt actually a physical dual core, it tricks the computer into thinking it's dual core, if you can get a cheap core 2 duo, those are really two processors in one... d is not, D out of those two processors is best though

wtf D is actually physically dual core

pentium 4 with hyperthreading tricks the comp into thinking that it has 2 cores...

pentium D --->

get the pentium 4 I am Extremely happy with mine.Dual core im not so sure about I really hated my pD so maybe a dual core might be better?

Haha, yeah...Pentium D is "real" dual core.

I don't know, I'd say they're about the same. Which do you value more, the multitasking or the gaming?? The Pentium 4 will probably be better for gaming since most games are only single-threaded, but the Pentium D would most likely be better for multitasking.

I'd say if you didn't care either way, go for the Pentium 4.

yeah pentinum D is a physical dual core whereas the pentinum 4ht is the one that tricks the computer into thinking it is dual core pr processing more than one thread at the same time as for whichc is better i thinmk overall the pent D would be better although if you got the p4 you would still be able to game good on it i would pick the pent D cos although it aint as good as the core 2 duoo it would prolly be better than a pentinum 4

no it is not, D might have 2 cores which i admit i said it didnt, but D does not have everything for each core, the cores share certain things on that processor, where as the core 2 duo has everything a single core processor has x2, D has 2 cores sharing certain pieces of the processor

umm cnt comment on the p4 but i have that pentium D and it works wonders with 2GB RAM which probably isnt needed 1 GB is fine but it runs fine

get an AMD X2. cheaper and does the job much faster and better. If u want I have a AMD x2 5200+ @ 2.61GHz, and a asus Mobo that will be good for your build. im selling it for 300. let me know

Pentium Ds are actual dual core. The differences between it and the C2D is the FSB, in the E6x models and their cache.
The Pentium D is better. I'm planning to get a Pentium D 940...in 90 years from now.

You've just answered the definition of a Pentium 4 with HT

lol well i knew the p4 HT acted like 2, one physical and one logical, but i read somewhere that the pentium D's share the cache and stuff, they have 2 cores, but share cache, apparently this isnt right, and of course i cant find the damn place i found it, SO i stand corrected, sorry for my dumbass mistake

Actually, Intel shared their caches for a reason I don't know. Maybe the dies waren't made for dedicated cache.

It's cache sharing, probably, but not on the L2...or was it L1?

Anyays, a Pentium D is dual core, and you've admitted your mistake. You're here to help and learn, so it's your benefit that you learn from your mistakes

Default Re: which is processor is better.

well how exactly does dual core work? when a single core has used up all the processing power can it just continue working at a good speed because it has the second core? Or are both cores used at the same time? Because I have heard from some where that having a dual core is exactly like having 2 processors built right in.

bullzi, Core 2 Duo shares the L2 cache between the two cores. This is a lot better than each core having its own L2 cache.
To put it simply, there are two people (the two cores) and each of the have their own water bottle. But one of them needs to drink two bottles of water to satisfy his thirst while another only needs to drink half of it. But they can't share in between for their paranoia of transferring disease and the likes. But if they share a giant pool of water, each can satisfy his own thirst by filling up their water bottle to the level that they need. Hope this helps

trollmaster, having a dual core is like having two processors work at the same time with different applications, or a single application if it is coded correctly. Think about it like building a house. One group of people can start with the foundation while another group can start deciding where the plumbing is going to go instead of having only one group build the foundation and then after decide the plumbing. Theoretically, they can build the house twice as fast.
