can someone clear me on this?...i played GE..but why only one core that processing?...the second core can go only 50%...it should be 50~50 isnt?

Coz GE is a single threaded game. It does not take advantage of a dual core. So basically you would get the same performance as that of a single core proc of the same speed, although the dual core will be slightly better as other tasks can be handled by the other core smile.gif

I think this is the confusion with the software written for single thread or multiple thread processing. Like you say software designed for single core processing and multiple core processing. I really think there's a good way to solve all these confusions. Right now we have problem with single thread processing software not scaling effectively with a multi-core processing. This problem can be worked around with 'reversed Hyper Threading' concept.

Hyper Threading was a concept to make the system acknowledge 2 processing cores where in actual fact there is only 1 real physical core. The fact it could handle more than one thread is because of its additional set of registers to hold an extra thread. The processing still goes one by one but with Hyper Threading you could ensure less idle states in the registers when work is actually done.

Reversed Hyper Threading however is still a very theoretical concept in which to make the system acknowledge multiple processing cores are one. Where two or more cores could combine to speed up a single threaded process. Some of the program instructions sets that goes into multiple level of processing could be done in parallel with the cores assigned. Or the system is smart enough to assign a few cores for this process while the remaining does the rest.

One of Intel's testing approach is the Core 2 architecture where it attempts to combined a few similar instruction sets to be executed as one. This is pretty ironic because the CPU always breaks instructions into micro instructions for 'easy digestion' but these micro instructions can be combined to be executed at once.

Current new games already start utilizing quad core. Hopefully more software would do it too.

Dual core is good enough for me. 4 cores = overkill nod.gif

4 cores and 8 cores MAKAN POWER like shit...

especially the Q6600... DAMM 105W
my Core 2 Duo E8200 only takes in 65W le

but if you compare the quad with Pentium Extereme and Pentium D...
Quad saves more power la...

yaya... multitask good with quad core...
BUT think twice... what kind of task we do?
gaming and chatting on MSN ? well not much task that fully utilize all 4 cores don't u all think?

more and more games are using quad cores

GOW around 75 percent and that means all the unreal engines including bioschock

Crysis Patch 1.1 uses around 70 percent of all cores depending on how much action..

so .. hmm quad core is it?? except the games will be rolling out pretty slow for pc ..

u comparing quad 65nm with dual 45nm proc of coz dual 45nm use less power then quad 65nm proc, u should compare quad with quad see how big diff
