dual core question

[Dead_reckon]

i have a question about my dual core pentium D. since each core has its own clock of 2.66ghz, and each core has its own cache of 1mb, that would mean that the effective clock would be 5.32ghz and the effective cache would be 2mb, correct? hope someone knows an answer to this.

Basically, a dual-core microprocessor performs like two processors, each of which can run its own threads in parallel, independent of the other, and each of which can access system resources independently. However, it's still a [highlight]single microprocessor[/highlight] according to most definitions, which view [highlight]each microprocessor as a single chip[/highlight] that fits into a single socket.

My understanding is No on the clock speed  but yes on  L2 cache.... << (revised) read this new link

But;  feel free to read this "novel"  of an article and see what you think. It seems to me, it's all about speeding up the processes  between cpu & memory.  Multi-tasking is the multi core theory with huge improvements in the cache*

thanks. but, if both cores are running at 2.66ghz, thats still pretty much two CPU's.. i can say it is far better than HT tech. hopefully i will be able to OC this CPU to about 3.4 or better with a Tuniq cooling unit, huge beast of a CPU cooler. i am still debating on what case to buy though. i have plenty of time to debate though, no job as of yet.

No, absolutely not.

I agree.
There is a major difference.
They cannot both do the same thing, they work on separate jobs.
So it will speed up multitasking but will not be any different than a 2.66GHz P4 doing one thing at a time.
As for the cache, it's 1Mb per core, not 2Mb between them.

That's the idea, it's 2 CPUs in one socket.
It's better than HT because HT is just simulating dual-core tech, it still only uses one core so isn't as good.
The 8 series are good overclockers, GX1 had a good link on this . . . 4.1GHz was it?

i believe so, this is why i bought the 805.. well that and the lack of funding in my build. although i wish that i had known that my board doesn't support the 9XX series pentium D's before i bought it.. i haven't got a clue if it supports the C2D's though. but, pentium 4's are still pretty quick, if i had to i suppose i could get one of em'.

I doubt that the board will support Core 2 if it doesn't support the Pentium D 9 series.
Your upgrade options are quite limited if this is the case, the bets you would be able to get is the Pentium D EE 840, 3.2GHz.
You'd be better off keeping your 805 and overclocking.

Why do you want to overclock anyway?

Free performance boost.

Let me rephrase that then.
If you are careful and take your time and are not too greedy or impatient, it is a free performance boost.
Risky, but rewarding.
There are downsides to everything, and also upsides.

True story!
