In regards to the first question which cpu is better....?
The first chip is an amd opteron dual core 2.0ghz processor 1000mhz fsb and the second chip is an Intel xeon 3.6ghz 800fsb if that helps. Does it depend on what my application is for or one or the other is just simply faster and better. Thanks.
Is the Xeon a Netburst or Core architecture chip?
A Core architecture chip would easily beat that Opteron but a Netburst architecture chip would probably be pretty close despite the clock speed difference (as Netburst is designed for high clock speeds even if it means less work is done per cycle).
Though I doubt anything with a Core architecture is up to 3.6 GHz yet so it probably is a Netburst chip. I suspect the performance would depend on what application you use though the higher FSB of the Opteron and more efficient design would probably help it to win.
It'll also use less power and produce less heat.
Amazon EC2 Now #42 Supercomputer, IBM BlueGenes in the Dust (readwriteweb)
The question among both cloud computing consumers and supercomputer clients
alike has been when the distinction between the little cloud and the big iron
would disappear. Apparently that boundary evaporated several months ago. In
its twice-annual survey of big computer power, the University of Mannheim has
reported that Amazon's EC2 Compute Cluster - the same one you and I can rent
space and time on today - performs well enough to be ranked #42 among the
world's Top 500 supercomputers.
How far down is #42? In terms of time, not far at all. When EC2 was but a
gleam in Jeff Bezos' eye, Los Alamos National Laboratory's BlueGene/L was
king. Now, the 212,992-core beast ranks #22. Roadrunner, the amazing hybrid
made up of 122,400 of both IBM Power and AMD Opteron cores, sits in #11.
Meanwhile, EC2 - whose makeup is a little of this and a little of that - has
achieved #42 status with only 17,024 cores.
