say you have a single core no ht chip. 1 thread could use 100% right.<br />
say you have a single core ht chip. 2 threads could use 100% 1 thread 50%.<br />
same with multi cores.<br />
this works fine for me as i can and do multi task but seldomly.<br />
but my question comes with more then two cores. if i have a 4 core cpu can i use 100% with less then 4 threads going? i hardly ever see this thing at more then 30% unless im folding. why limit the threads to one core each and not let the whole chip cruch the data? or can you?

</div>Yes you can. Its not all about threads. Its about how much processing power that individual program needs to carry out its task.

How come only 30% when folding? I am folding 100% on both cores...

only 30% doing every day stuff.<br />
you figure each box with the graph is 25% on a four core unit. one program can only run the cpu to 25% leaving 75% pf the cpu untouched.<br />
there should be a way to run multi core cpus at 100% usage with only one folding program running.<br />
i want a kentsfield at 4ghz blasting out a wu every 5 mins. not 4 every 20min you see what i mean?

</div>You cant get a single threaded program to operate on all 4 cores. You would only be able to run 4 instances...1 on each core.

The Folding program is a single core program. Just run one on each core. Production speed will be the same There is no difference between 1 WU every hour (running all four cores on 1 WU) or four WUs every four hours.

i dont care about perduction speed. i want pure speed to make all four core run as one monster like a 4ghz kentfield working like one 16ghz chip or maybe two 8ghz guys.<br>
so when intel puts out the 8 core units the chip will really only do huge servers anygood then? cause i never have 8 things going at once<br>
just seems like a waste of silica to me, kinda.

This issue is far more complex than people are lead to believe.<br><br>
In theoretical understanding processing power can not be combined in regards to thread processing.<br><br>
If you were to run a complex program that was able to use resource dividers then in actual fact you could split one thread between four processing cores. This is therefore technically a symmetric multi processing environment.<br><br>
A thread, in the way we look at it, is a set of instructions designed to operate under one logic processing unit i.e. Central Processing Unit. However if we were to separate the thread into a four part thread, so 25% each. You would then be able to process that single thread spread over four cores.<br>
There are some applications that are capable of doing this, however we don't have many at this current moment in time (most are CAD applications).<br><br>
Currently four cores will not be useful for gaming or raw processing power. They will be good for advanced multi-tasking however <img alt="" class="inlineimg" src="/images/smilies/smile.gif" style="border:0px solid;" title="Smile">

Depending on how quickly software developers will jump onto this <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" /><br />
<br />
Agreed, for a while, it will not give any benefit. <br />
<br />
Do realize four 4GHz cores will never act like one 16GHz core. Even if an application splits its processes over all cores equally, it's still not a 16GHz CPU. Yes, there will be a lot of performance increase, but that increase will not be 100% (given the additional processes that need to be run to split the processes and combine them in the end).

im just trying to see if i can get the other three guys in my computer to do something. they all just watch at one core works. remindeds me of my work.

Depends. Some applications already run on dual cores (photoshop). If you want to fold, then you can assign one run of the folding program on each core, thus running 100% on all cores<br><br>
If not, and you're just an 'everyday' user, you are probably better off settling for a E6400 or E6600, and just wait until Quad core (or even more) becomes more useful and/or cheaper

With dual core cpu's becoming the standard, I hope soon we'll see alot more programs starting to take advantage of both cores fully. Like they said, certain things, like folding, you can just set it up to run multiple instances. But hopefully the writer of the folding code is working on a new version to accomodate dual+ cores.<br />
<br />
I am deffinitely looking forward to games and other things I do, fully taking advantage of both cores as well. It's all coming, the software will catch up, sucks having to wait though lol. I still love having two cores anyway though <img src="/images/smilies/thumb.gif" border="0" alt="" title="Thumb" class="inlineimg" /> my four conroe cores between my rigs fold like monsters!
