AMD has announced its new G3MX memory controller which will allow double the memory capacity on high-end server and workstation systems from 8 to 16 DIMMs. The firm says the technology will become available in 2009.
"By installing the memory buffers, we can extend the existing memory channels of these future processors and run the interface faster, moving more data down it," Diane Stapely, strategic manager for Opteron systems at AMD, told vnunet.com.
Brookwood said that the technology offers benefits beyond the database and virtualisation servers that AMD is targeting. Multi-core CPUs may also have an impact.
"As you have more cores you need more memory, and pretty soon you need more modules than you can control through current interfaces," he explained.
"You cannot put more memory controllers on easily, so you need to go on some serial approach."
G3MX has another advantage in that it uses cheaper SD3 Dimms rather than specialised fully-buffered memory modules, Brookwood noted.
The analyst warned, however, that G3MX should not be crowned as a game-changing technology just yet.
