Mindaugas, The Anandtech results appear to me to support a 2.5 GHz Barcelona performing better than the available Intel CPUs overall. If you can wait for the 2.5 GHz AMD parts to come out, they'd be a better bet IMO especially considering 4 sockets. In fact, have you seen quad QC Intel benchmarks? BTW - Can someone please get Anand a decent PG benchmark kit? :-) At least we can count on excellent PG bench results from the folks at Tweakers. - Luke > -----Original Message----- > From: pgsql-performance-owner@xxxxxxxxxxxxxx > [mailto:pgsql-performance-owner@xxxxxxxxxxxxxx] On Behalf Of Mindaugas > Sent: Tuesday, September 11, 2007 12:58 AM > To: pgsql-performance@xxxxxxxxxxxxxx > Subject: Barcelona vs Tigerton > > Hello, > > Now that both 4x4 out it's time for us to decide which one > should be better for our PostgreSQL and Oracle.
