I was at a users meeting yesterday for the software I use and AMD was a vendor there. I am interested in their new procs because I have run into the 4GB (really 2 or 3 depending on the OS) limitation quite a few times. Any way, I spent some time talking with there rep about the other not so obvious advantages of their procs. The big one is their integrated memory controller. From what I've read it basically off-loads all of the memory bandwidth from the FSB, which is a big deal since memory usually uses up a large portion of the bandwidth. But, what I didn't know is that this allows for a seperate memory bank for each proc. According to the rep, their memory bandwidth per proc is 5.3 GB/s. By adding an another proc. the memory bandwidth scales proportionally to 10.6 GB/s and so on. And all of this is off of the FSB. This should be a huge improvement in performance of multi-processor machines. Has anyone seen any reviews, benchmarks or articles about the multi-proc Opteron 64 systems?
