Dual - single core..How much faster is it?

How much faster is a dual core chip compared to a single core chip of the
same speed?

I am sure its not twice as fast..

For single threaded applications it would be slightly slower due to
overhead and shared resources, BUT you get some back by off loading
operating system threads to the second processor. Full up load them
both, 50-70% better system thruput. Remember the HD and memory is shared.

I have an Athlon X2 4800. With this chip, I am capable of running Half Life
2, encode a movie, run my antivirus with no hiccups. I know I haven't fully
realize the full potential of this chip either. No regrets here with dual
core.

I chuckled at this, since Intel dual core procs are two cores fused into a
single package, but are not true dual core. Intel dual cores cannot see
each other and can only communicate through the Northbridge chip.

AMD dual core processors are built as dual core and have the crossbar for on
die communication at 2000MHz.

In a recent test, AMD dual core thoroughly trounced the Intel dual core
wanna-be;

It wasn't even close.

After reading the round-by-round account of our dual-core desktop CPU
prizefight, it should come as no shock that AMD's Athlon 64 X2 chips are the
runaway victors here, laying out the Intel Pentium D and Pentium Extreme
Edition 840 chips pins up. If we had to call out one chip, AMD's Athlon 64
X2 4400+ is an outstanding bargain given the competition, but as our results
show, any AMD dual-core CPU will serve you better than its similarly priced
Intel equivalent.

If you're wondering why there's such a striking performance difference
between the two companies' processors, it likely has something to do with
the memory controller. Among the technological differences between the two,
AMD's memory controller--the component that sends information back and forth
between your system's CPU and the memory--is an integrated part of the
Athlon 64 X2's chip architecture. Intel's memory controller, however, exists
as a separate piece of silicon on the motherboard. The additional distance
between the CPU and the memory controller adds to the processing lag time
and likely plays a part in Intel's lower scores.

Moral of the story....AMD is the only choice.

Sad to watch Intel, the once mighty giant, stumble about.

Kenny;

You;ll be better off posting about the AMD X2, which outperforms the Pentium
D in every test (see my earlier post). The Intel chip is two procs fused
together, but is not a true dual core.

Forget Intel. It is not true dual-core. Carey, I suggest that you learn
about AMD.

A link towards an external site is legal. I did not say I would copy the
content and place it on my site.
