AMD Unveils Rival for Intel’s FB-DIMM, develops G3MX Memory Tech

Advanced Micro Devices on Wednesday unveiled a new technology that would enable next-generations of servers to utilize massive memory capacities, something, which will substantially boost server performance. Besides AMD, IDT and Inphi, some of Intel’s FB-DIMM backers, also participate in development. The new technology currently called Socket G3 Memory Extender (G3MX) is a part of AMD Opteron platform infrastructure due to be unveiled in 2009. The G3MX will support DDR3 SDRAM and will extend the total memory footprint in future AMD Opteron processor-based systems. Even though G3MX is designed in a way similar to Intel’s FB-DIMM, it uses industry-standard memory modules and is a typical memory extender akin to those used by such companies as IBM and HP. It is unclear, however, whether the technology supports mirroring, hot-plug and other capabilities for high-end servers.
