AMD Opteron 6174 Processor packs 12 cores of crunching power

The inevitable future for the computer processor is the addition of more and more cores to improve performance for those tasks that are highly parallelizable or just enjoy warming up a datacenter as quickly as possible.

AMD’s Opteron 6174 “Magny-Cours” processor is a parallelized application’s dream with 12 cores to play with and some tweaks thrown in to make it as efficient as possible. AnandTech has a look:

You probably heard by now that the new Opteron 6100 is in fact two 6-core Istanbul CPUs bolted together. That is not too far from the truth if you look at the micro architecture:  little has changed inside the core. It is the “uncore” that has changed significantly: the memory controller now supports DDR-1333, and a lot of time has been invested in keeping cache coherency traffic under control.

A slick chip but there might be some tuning to do for software to make the most out of it.
