And especially for Oracle we really need = such server to squeeze everything from Oracle licenses. Both of the databas= es handle OLTP type of the load. Since we plan to buy 4U HP DL580 or 585 and only very few of them so powe= r ratings are not very critical in this our case. First benchmarks (http://www.anandtech.com/IT/showdoc.aspx?i=3D3091) show= that Intel still has more raw CPU power but Barcelona scales much better a= nd 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?= :)
