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. And especially for Oracle we really need such server to squeeze everything from Oracle licenses. Both of the databases handle OLTP type of the load.
Since we plan to buy 4U HP DL580 or 585 and only very few of them so power ratings are not very critical in this our case.

First benchmarks (http://www.anandtech.com/IT/showdoc.aspx?i=3091) show that Intel still has more raw CPU power but Barcelona scales much better and also has better memory bandwidth which I believe is quite critical with 16 cores and DB usage pattern.
On the other hand Intel's X7350 (2.93GHz) has almost 50% advantage in CPU frequency against 2GHz Barcelona.

Regards,

Mindaugas

P.S. tweakers.net does not have both of those yet? Test results far away? :)
