Can anyone explain the difference between Dual Core and Dual CPUs?

[Caveman]

Seems like Tyan had a dual CPU board... What is dual core, and how is it different from the previous technology....?

Dual core is as its ame says, it has a dual core in one chip. Dual proccessors are two dofferent proccessors in 2 different sockets. My little experience tells me that dual core proccessors suffer from temperature problems and that they have a little smaller speed since they use the same bus for transfering data. their advantages is the smaller power consumption and the smaller space they take (imagine a motherboard with TWIN Volcano 12+ heatsinks).

Nothing really. Just two CPU's slapped on one die sharing the same memory bus. Dual Core CPU's are supposedly aimed to attract the Desk Top Market users so they don't have to go out and buy multi-socket motherboards to get the same performance as a workstation or server computer while multitasking.

I don't expect to seem them around for a bit. As you can imagine putting two cores on one single die could make things a little hot under the hood. Not to mention the huge power consumption.

Even if they pass the manufacturing hurdle of heat and power consumption, they would still be trying to market a chip for users that really have no need for it. Most applications on a desk-top are single threaded and would only need the use of one CPU core.

Not unless the dual core chips are based on Dothan.
They appear to be faster than Athlon 64 chips, clock for clock, cooler and only 21watts.

Now a dual-core Dothan running on a 925 desktop chipset at 3.0GHz would rule!

the 90nm AMD's doesn't pull that much power, at their current speed.

true Dual CPU is the way to go
opening up the case and seeing 2 big heatsinks is just so damn cool

will get a dual setup eventually again, I miss mine that I had for a few weeks

Not really. It would likely be bandwidth starved. I bet it would be no more than a 3.2 Ghz Intel with HT.

And from what I heard, the Dothan is rumored to be Intel's primary Single CPU. With all the rumors going about, I'm surprised no one has mentioned the Pentium-m technology being introduced to dual core. It would be perfect for it, no?

Of course, there will be dual-core dual-cpu as well... not to mention dual-core 4- and 8-way Opteron systems.

Then you can have your dual heatsinks.

I know this is an old thread, but it is appropriate to my question.

I was thinking, once games are written to address two separate cores, won't dual CPU systems become more powerful than dual core. What I am saying is, when Intel release their Pentium 4 840 (2x3.2GHz), won't dual Xeon DP 3.8Fs be better?

(Also, I can't post this in a new thread (The reason will become apparent), but I can't create a new thread, when I click the link, nothing happens, what can I do to resolve this?)

Well, I think it's pretty obvious that two DC CPUs will be better than one, since then you have four cores as opposed to two.

You probably have popups blocked from the site. Turn off any popup blocking and it should work, or try another browser (maybe you have spyware that's jacked up your IE).

Sorry, I meant the two single core Xeons. Would two single core Xeon 3.8s be better than a dual core 2x3.2?

 

[Gamerz 21st Century]

I don't use a popup blocker, and I don't use IE, I use Firefox, though I have tried with IE and I have the same problem. I use Ad-Aware and Spybot S&D, and I still have the problem after having run a full virus scan with Norton and a full spyware scan with both programs.

Very hard to say without seeing the real running DC chips, and it's probably largely dependent on the benchmark. I think it's pretty obvious that two 3.8s, each with their own memory bus, would be better than two 3.2s sharing a memory bus. But at the same clock speeds, it might not make a big difference.

Then I don't have a clue, sorry. You could try in Forum Issues.

Aimed at desktops my ass! Sure they will hit desktops, but notice the first dual cores are Opterons?

And yes, a 2-dual-core-cpu setup in a Tyan K8WE with 2 6800 Ultras would beat 939 dekstops mercilessly into a corner, slap them around, and say B@TCH! Make me a toasted cheese!

Greating thing about intregrated dual channel memory controllers is that dual cores wont be to starved for bandwidth. They render Intel's xeon crap utterly useless because they shared a single controller, whereas opterons get a controller per cpu die.
