Has anyone seen any performance metrics comparing the Opteron 6-core
Istanbul class processor aginst the 4-core Xeon e5500 series
processor, esp running a dataase?  Or has anyone compared these 2
processor options before ordering a Postgres server?

The 6 core processor should offer a clear edge but these AMD
processors are cited for relatively slow L3 cache speeds compared to
their Intel counterparts.

4-Core Intel Xeon E5520 (2.26 GHz) Processor      VS
6-Core AMD Opteron Model 2425 HE (2.1GHz} Processor

Any comments?
