Multi-Core CPU’s Still Not Being Utilized

Intel and AMD are con­stant­ly pump­ing out new proces­sors with more and more pro­cess­ing cores.  But can cur­rent OS soft­ware real­ly uti­lize all that pro­cess­ing pow­er?  Today a Quad Core CPU is eas­i­ly afford­able to most peo­ple.  Mul­ti-Core CPU’s have been out for years now and soft­ware is still being writ­ten in a way that does­n’t uti­lize the pro­cess­ing pow­er of Mul­ti-Core CPU’s.  Use of Mul­ti Core appli­ca­tions may require a rethink­ing of win­dows “Although mod­ern oper­at­ing sys­tems do true mul­ti­task­ing and scale with the addi­tion of more cores, Probert thinks that to take full advan­tage of the new won­der­ful­ly pow­er­ful hard­ware we have, it will require a rework­ing and rethink­ing of Win­dows.  Of course, with the rapid­ly grow­ing num­ber of cores, espe­cial­ly in light of Intel’s exper­i­men­tal 48-core CPU, an alter­na­tive method would be to devote at least one dis­crete core to each appli­ca­tion.” Says Toms Hard­ware.
A ded­i­cat­ed core for each appli­ca­tion is a inter­est­ing con­cept… so what would you do when you have more then say 4 appli­ca­tions open on a Quad Core Proces­sor?  I’m curi­ous to see how this plays out over the next 10 years as we can expect the amount of cores being used to eas­i­ly dou­ble.

    Per­son­al­ly, I think this is a sit­u­a­tion where, for the vast major­i­ty of appli­ca­tions, hard­ware tech­nol­o­gy is waaaaay ahead of soft­ware devel­op­ment — and will like­ly stay there for some time. Until broad-scale soft­ware devel­op­ment catch­es up to the tech­nol­o­gy, there’s lit­tle rea­son for a con­sumer to pay top-dol­lar for the newest, badass-est hard­ware.
    IMO, take the mon­ey you’d spend on that 48-core CPU and invest in a hefti­er pow­er sup­ply, faster mem­o­ry, a more pow­er­ful graph­ics card (s) and a bet­ter cool­ing solu­tion for your next rig.

    Fur­ther­more a lot of com­pa­nies don’t opti­mize their soft­ware so they become mem­o­ry and CPU hun­gry. So where they could be using 1gb of ram with 1 cpu core they are instead hav­ing to use 4 cores and 4gb of ram. Bad Com­pa­ny 2 is a prime exam­ple of this issue.
    Gen­er­al­ly when I build a new rig I look into the video card first and fore­most and then build the rest of the PC around it because 90% of what I do is video card inten­sive.
