It has 4 physical processors and in programs which support hyper threading there are 4 more virtual ones however these are not as fast as the 4 physical ones.

Each core can handle two threads at once, if supported. So you kind of have 4 dual cores, sort of.

It works the same as the old P4's that had hyperthreading. It could process two threads at once but was only single core.

not a lot of games are multithreaded but some programs are. Programs geared towards rendering and that type of thing will eat all the cores you have :]

but as stated above, it's 4 physical cores with 2 threads each making it like 8 virtual cores or something like that

No not at all..

Its 4 Physical Processors that are threaded to act like 8

Games really don't recognize them

Majority of current games only use one core so your not even using all 4 cores the I7 physically offers.

Most games/programs still use only one or two threads. So you will have 6-7 threads just sitting there doing nothing.

Would love to see the sort of multi-tasking possible with the i7.
