Why even Dual Core?

post #1 of 66
Thread Starter 
I'm a noob. But as far as I understood it, one of the processors in Dual Core is mostly idle.
As as people here probably want to play with their computers,
why buy a expensive Dual Core?
Why not get a powerful single core and use the money for some more performance somewhere else?

That exactly how I feel - Which is why I bought a 3700+ as a cheap upgrade to my current rig

Because ur wrong, one of the core is NOT idle. Its only idle when its not being used.... like any cpu.

Dual core works faster (and almost 3 fold in encoding) then single core and improves performance...*link*

the fx-57 is the fastest single core for games, but is still out run by x2 4400+ in games and in encoding the D 920 does better then the fx-57

So the two cores will share the work?
I got it explained as only one of the cores can be used for gaming,
and the other one will only be used when you do something else at the same time. Like ICQ.
And I'm talking only the benefits of gaming performance.
Its fine that it is fast in stuff like video editing, but I dont use that.

Currently, the most powerful and best value for money CPUs are all dual core to my knowledge and they are the Core 2 Duo / Extreme CPUs and their variants. I have heard that Intel will release a single core Core 2 based CPU in the near future, but I don't know they will for sure.

Windows XP/2K and MS office utilise dual core CPUs to improve performance. Many games do not use dual core atm, but they still benefit from dual core, in that one CPU can be dedicated to the game, whilst the other deals with background OS processes.

Dual core also means that you can run one application constantly (like folding @ home for example) whilst still being able to play games, use DTP software or surf the net without a real perceptible decrease in performance, compared to doing the same thing with single core, where the performance hit would be noticeable. Also, I've found that switching between a full 3D game and desktop (ALT+TAB) is a lot faster with dual core as well, which is a nice benefit for those of us who like to check e-mail and surf the net etc in-between rounds on AAOL .

If your question was about quad core (coming very soon) I'd agree with what you question implies, as I don't personally believe quad core is worthwhile with current software, but dual core really does offer worthwhile and perceptible benefits over single core, more so than quad core does over dual core with current software, imo.

they both work together for gaming, but you can set affinity to a core if your multitasking

I wanted to get a Athlon 64 3700+ and overclock it.
Would a Intel Dual Core in the same price region be better?

sooner or later noone will sell single core's because intel and amd are only working on dual/quad core processors.
