dual core question

on my computer, why does the 2nd core not come into play when the 1st core reaches 100%? it seems more like the two are always even.. is this how the technology works?

yeah, im pretty sure. i think they are designed to process more than one thing at a time, therefore both cores working simultaneously is better than one reaching max and the other kicking in. if it did that, one core would be working a lot more than the other and would possible wear out faster.
 
from all of the screens that i have seen of the usage of dual core cpu's they have always been at the same level. Thats the way it should be because of the way multiple threads are evenly balanced over the two cores.
its not the same as a P4 with HT technology because the virtual processor uses the processing power thats "left over".

- Did you set process affinity?
- Does the mobo recognize the 2nd core?
- Does the OS recognize the 2nd core?

if it did that, one core would be working a lot more than the other and would possible wear out faster.

Dude. Switching occurs 1.8 billion times per second, i dont think wear and tear is an issue here

i was talking about if core #1 worked until it reached full load and core #2 remained dormant until core#1 was at full load. core#1 would be working a lot more than core #2, therefore more strain would occur on core #1. that was his original question.

Yes im aware of that. My point still stands.
 
two processors cant work on one thread. its that simple. this is why dual core isnt better for single thread applications, such as most games.
if its one huge process in one huge thread that uses alot of processor, yes, it will put one core at 100%, leaving the other one to take care of other processes. ultimately this is why they are better for multitasking, i can burn a dvd and run an ad-aware scan without any lagging at all.... its just the way it works.
 
do you guys think we'll see games utilizing dual core technology in the near future, or maybe even patches for today's games? (or maybe that would take an effort which would be like creating an entire new game, i honestly don't know.)
 
it will be happening very soon, a heard the next unreal tournament (or current cos i cant remember when i read it) will be taking advantage of multiple threads

- But last time i checked nobody here is using DOS so we dont have to deal with IPC and task switching. Windows on the otherhand IS multithreaded so quite possibly the most popular program used by members of this forum will benifit from the second core.
- Very few games are single threaded

A better example would be to encode a DVD but regardless, the limiting factor there would be the harddrive not so much teh CPU

They been out for some time now. As for effort, it easy to spit out threads ... it a serious f******************************* pain in the ass to debug multiple threads
