I#%92m a BI developer and have a hardware question. We have recently specked up some new servers for our datawarehouse and OLAP solution, we have opted to go 64bit. A consultancy suggested 4 dual core processors per box (around 3GHz Xeons) with 16gig ram. On presenting the consultants report to our hardware manager he has now kitted out the servers with 2 (1.6MHz) dual core Itanium2#%92s. Also, the boxes only have 2 sockets so there#%92s no room to expand in the future. Without getting too caught up in what to do with the hardware manager what is the general consensus? Generally speaking should 2 (1.6MHz 64bit) dual core Itanium2#%92s outperform 4 (3Ghz 64bit) dual core Xeons? Any science or performance comparisons to demonstrate the case would be very much appreciated, mind you so would a yes or no.
