Now, I hear rumors that AMD is to be preferred over Intel for performance
From what I have read in the past, specially in the postgresql list, it seems the AMD64 cpus do better with Postgresql. Possibly because of better bus architecture.
I think this is not current information; the new woodcrest architecture performs mucg better, although this is deduced from this thread's discussion...
Except this thread has largely glossed over the importance of memory bandwidth, which is exactly the reason why Opterons have been beating Xeons for several years. Last I'd heard, things were fairly close between the two, but that would matter on how many cores and physical CPUs you have.
This is still true, even with the latest Intel Cores. For stuff that does massive memory work, AMD's seem to be faster. However, for non-memory intensive applications, the Intel procs are smokin' fast.
It would be good if someone could do a database benchmark for some of the larger parts.
Something else worth mentioning... a lot of work is being done to improve PostgreSQL scalability for larger numbers of CPUs. If you're looking at anything over 4 cores, I recommend going to 8.3 ASAP.
Hmm. Sounds like you know a lot about database stuff (database architect!), maybe you would be a perfect candidate for the benchmark? :)
