intel dual core question

[sonoma1993]

Why is it for the intel dual core processor, for them to communicate with each other they have to go through the front side bus?

because intel hacked two cores in same socket and did little redisgn work unlike amd. Yonha will have abitly for both cores to communicate on die.

To be more specific, The Intel processors were not designed to be dual core (unllike AMD).
Some people call them "twin core" and not dual core because they are basically 2 Prescotts that are glued together. This has advantages and disadvantages...
They are cheaper to produce than a true dual core because a flaw in one of the halves doesn't ruin the whole processor.
But, they have a much higher latency in cache coherency and so they are less efficient and slower.

Yonah will not be like the X2s either because they will actually share a single cache instead of using a crossbar on the processor to talk between individual caches. This may be faster or not, depending on how it's implemented...we will have to wait and see.

Easy way for them to play catchup to AMD so they dont look dated/obsolete/left behind and cost. Intels "dual core" was an after thought and it shows.

Yep, like the other said, it was just slapped together, because Intel didn't have anything at all to compete with the AMD dual cores. I have an 830, cause I could get it for $160, but it wasn't even worth that if you ask me. Idling at 50c, loading at 70c, which is just below throttling temp, at stock speeds, with a decent aftermarket cooler. My X2 OC'd to 2.618ghz on the stock AMD cooler gets to 51c under load and idles in the 30's.
