Anyone trades with quad core?

Quote from Triple X:

You would be better off with two Xeon or Opterons on the same board. The dual chipsets can share resources, wheras the multicore chips can't.

My HP dual core doesn't seem to be able to share resources. Is that different than "dual chipset"?
 
Quote from kiwi_trader:

The quad core will greatly improve the problem of a single threaded hungry application.

It will get 1 out of 4 processors (which it might well use at close to 100%) but the other 3 will be available for the system and other applications.

If you want it to have half the machine's capability then just get a fast dual core :cool:

The only reason to prefer 4 cores is for multitasking applications (no needed for traders)
Otherwise.... the best machine you can build right now is with the Core 2 Duo E6850 :cool:

Quote from gnome:

Most trading setups are multi-tasking. By having additional core(s), the total load can be spread around for better overall performance... at least, theoretically.

What would be especially beneficial would be a program which allows the user to manually assign certain tasks to a core and set priorities. Then have Windows mediate the lesser tasks.

Anyone know of such a program?

Would this page on Tom's Hardware website be helpful too you...

I agree with gnome. Putting in more memory and using 10,000 rpm drives would probably benefit most traders more than a quad core would.
 
What does exactly mean that a dual chipset PC can share its resource between 2 x CPUs (for ex: 2 x Intel 5000 series Xeon or 2 x AMD 2200 Series Opteron) while a chipset with 1 CPU quadcore (Q6600) can't?

That's not true. It's not about 'multitasking' (I assume you mean 'multi tasking' = running several programs). It's about multi threading. One task can be divided up into several threads. If your trading platform is divided in lots of threads (each l2, chart, T&S etc in its own thread for example), then a quadcore cpu is really the cpu to buy. However, I'm quite sure that most current trading platforms are still single threaded and therefore quadcore isn't really useful.

You can check out if quadcore might be useful for you: d/l process explorer: http://download.sysinternals.com/Files/ProcessExplorer.zip
then see how much threads your current trading platform uses, open up a new chart/L2 and see if it adds an extra thread for it. If so, then quadcore might be useful ...

According to testers, multitasking gets a nice overall performance boost as the OS spreads single thread apps among the available cores. Biggest jump in performance is in the dual core.... smaller improvement from dual-to-quad.

Do you mean there is no great advantage switching from a Pentium D 945 OCed @ 4Ghz to a Quad6600 OCed @ 3 Ghz?
:confused: (here we have more cores 4 vs. 2 but running slower although with more available 4 x 2Mb cache vs. 2 x 2Mb).
