Performance 5650 vs. 2650 - forum topic by mlthomps

Hi,
 
I'm a new TD DBA and been tasked to see about going from a 2-node 5650 to a 2650 we have.  I found that the published scan rate for the 2650 is about 38GB/s, but cannot find a published rate for the 5650.
 
Any ideas on where I can dig this up or how I would calculate it?  I cannot runa simple test on, say, a 1TB table and see the actual rate as it's a busy system.
 
Thanks
