Will be ordering  an Athlon 64 X2 for a M2N-SLI DELUXE MB shortly

Question I have is Whether to get the

AMD Athlon 64 X2 6000+ Windsor 3.0GHz 2 x 1MB L2 Cache Socket AM2 125W
Dual-Core Processor

Total Reviews: 1416  4x winner customer choice award


AMD Athlon 64 X2 6400+ Windsor 3.2GHz 2 x 1MB L2 Cache Socket AM2 125W
Dual-Core Processor

Total Reviews: 477

Seems the slower of the two is more popular.

The only differences are the speed and the price.  Take a close
look at those prices on Newegg: the 3.2GHz processor is reduced
from $169.  There is no such reduction shown for the 3.0GHz.  The
way computer prices work is that you always pay for the very fastest
components and these prices plummet towards more normal prcining
levels as they mature.  You are seeing that here.

If you look at the orginal pricxes, which would you pay? $89 for
3.0GHz or $169 for 3.2GHz?  Most would go for the former simply on
the economics.  That doesn't apply anywhere near as much now but
the 3.0GHz still wins on a dollar per gigahertz measure.

Yes, lower end CPUs always outsell midrange CPUs which is
what the 2nd one's price-point made it until recently.

Also, they both would overclock to roughly the same speed,
so the cheaper, slower default speed CPU will make for a
faster system because it will allow a  higher bus speed
before it runs out of o'c headroom.

However, I could not recommend either of them today.  They
are bot the old 90nm process size that run very
inefficiently, note how they are rated for 125W at a mere 3
to 3.2GHz speed.  You could buy a 4050e 45W AM2 chip for
$40, overclock it to roughly 3GHz and have it still be less
than 100W, or similarly so with the slightly higher speed
models rated for 45W or 65W.

Personally around $100 I would go for a Phenom but I don't
know what tasks you'll use the system for, though those
triple or quad core CPU also get up there in wattage.
Beyond that sticking with a Athlon X2 I would at least limit
it to 65nm process size instead of 90nm for better

If you want to compare the overclocking performance, you can try
the site.

The 6000+ CPUZ results show some 4GHz overclocks. It all depends on
what cooling was used, and how much voltage was applied, as to whether
it was easy or not.

The 6400+ processors aren't that much different. You'd have to do a scatter
plot, to see the difference. And there may not be enough proper
data collected by this site, to do a good job at that. (Plot voltage
versus frequency, for the two processors, to see if the best
fit curve shows significant value in the more expensive processor.
Sometimes the Vcore voltage is noted in a screenshot for the
entrant, but it would be a slow process to assemble data
that way.)

There used to be a site that tracked frequency, applied voltage,
cooling method (air, LN2, dry ice, water, phase change), and
with that site, it was easier to figure out what you could
reasonably expect from a processor. But due to abuses by posters,
and the response to the site with respect to the abuse, the site
became useless. So now there isn't a site with data ready to
put in a scatter plot.
