AMD Opteron vs Intel Xeon is different than AMD X2 vs Pentium D.

For AMD X2 vs Pentium D - I have both - in similar price range, and
similar speed. I choose to use the AMD X2 as my server, and Pentium D
as my Windows desktop. They're both quite fast.

I made the choice I describe based on a lot of research. I was going
to go both Intel, until I noticed that the Intel prices were dropping
fast. 30% price cut in 2 months. AMD didn't drop at all during the
same time.

There are plenty of reasons to choose one over the other. Generally
the AMD comes out on top. It is *not* 2X though. Anybody who claims
this is being highly selective about which benchmarks they consider.

One article is nothing.

There is a lot of hype these days. AMD is winning the elite market,
which means that they are able to continue to sell high. Intel, losing
this market, is cutting its prices to compete. And they do compete.
Quite well.

Cheers,
mark
