AMD Bulldozer to have faster memory controller

Posted on Thursday, September 16 2010 @ 15:27:14 CEST by

AMD revealed its Bulldozer architecture will feature a redesigned memory controller. The new design promises to deliver faster memory access times, both locally and remotely:
"There will be enhancements to our memory controllers, things we canot talk about just yet, that we expect to help reduce the time to access memory, both locally and remotely," said John Fruehe, John Fruehe, the director of product marketing for server/workstation products at AMD.

In previous-generations AMD Opteron multi-processor systems it took microprocessors two hopes to reach the information located in memory banks of other CPUs, in takes just one hope for a current generation AMD Opteron processor to reach the data in others' memory banks. One of the ways to speed up memory transfers in multi-chip systems is to implement features like HyperTransport Assist, a feature that was introduced with six-core AMD Opteron. But at present it looks like AMD's next-gen processors will not only improve memory accesses to remote memory banks, but also to local memory.
