AMD OPTERON 64BIT VS Xeon 3.6 64bit
 

Okay so here it is, 3 to 2 AMD Opteron 250 duel processor system beats the new xeon 3.6 64 bit systems.

There were five tests:
SQL Stress Tool Benchmark (Reads)
Xeon 3.6GHz - 105295*
Opteron 250 - 103198
SQL Stress Tool Benchmark (Writes)
Xeon 3.6GHz - 42102*
Opteron 250 - 41266
Vendor Heavy Workload Test (Reads)
Opteron 250 - 252942*
Xeon 3.6GHz - 242817
Vendor Heavy Workload Test (Writes)
Opteron 250 - 252836*
Xeon 3.6GHz - 242810
Vendor Heavy Workload Stored Procedures
Opteron 250 - 3161*
Xeon 3.6GHz - 3035

Intel is getting close but has yet to overcome the fact that AMD is ahead of the game. So all you host out there, I suggest you stop using those Intel Xeon processors and go for the opterons, cheaper, faster, and much more stable.

I used to be an intel lover but now I must say my new duel opteron system smokes. So you test and make the choice, Im telling you, Opterons are the future.

I love AMD they are always staying that one step ahead

Hmmm and how about Linux/FreeBSD compatibility?

Linux and bsd have both releashed x64_86 addition OS they run very well with the opeteorn 64 bit systems

Red Hat Enterprise Linux 3.0 ES Now Supports AMD64
Red Hat Enterprise Linux 3.0 includes three versions:

WS for workstations
AS for mission critical Enterprise servers
ES for small to mid-range servers
Initial releases of Red Hat Enterprise Linux 3.0 ES only offered x86 (32-bit support). However, responding to customer requests, Red Hat has now expanded ES to include 64-bit support for AMD64 processors.

in support :)
