Intel chips cannot begin to compete with AMD dual core...
First, Intel Dual core shares a single 1MB L2 cache, and it is an inclusive
cache, not exclusive.
AMD has a separate 1MB L2 cache for each core, and each cache is exclusive
(meaning that the data in the L1 data bus in not duplicated in the L2 cache
as it is in the Intel).
The two cores on an Intel dual core cannot communicate directly with each
other through the crossbar. They can only communicate through the
Northbridge chip. AMD dual core can talk directly to each other, through
it's integrated crossbar and controller, at the full effective speed of the
processor.
AMD dual core have an onboard memory controller and communicate with the
AGP/PCI-E/SLI?RAM through the Hypertransport bus at 2GHz in bidirectional
mode. Intel dual core procs have no onboard memory controller, and they are
locked to either a 533Mhz or 800MHz Northbridge FSB, slowing everything down
and introducing wait states, as this is a simplex system and can only send
and receive in separate clock cycles.
AMD dual core, because of it's architecture, can be a drop in replacement to
any 939 pin motherboard that can support an AMD FX chip (95% of the 939 pin
mobos made in the last 15 months fall into this category). Intel dual core
requires a new (and very expensive) motherboard. This negates the savings
on the chip.
But when Intel moves to the next-generation 65-nanometer chip-fabrication
process, the company will introduce a new desktop processor code-named
Presler that encloses two die in one chip package. Presler will look like a
multicore processor to the operating system, but inside, it will actually
have only one core per die. That's not quite a true multicore processor.
Here is a link to more information about the Presler core:

So, as you can see, Intel will continue it's time honored tradition of lying
to it's paying customers while spending truckloads of cash making them think
that Intel chips are better than AMD.
Buyer beware.
