Forget DDR3, fastest DRAM is XDR4.8GHz octal data rate blows mindsBy Wily Ferret: Friday, 05 October 2007, 8:34 AM THINK THAT INTEL'S X48 chipset will be fast, with 2GHz DDR3 memory to accompany it? Think again - Intel's old pal Rambus has them beaten like a grouse in hunting season.Elpida has just announced that it has the industry's fastest DRAM, with its new XDR part running at a meltingly fast 4.8GHz. XDR is the Rambus standard for next-gen platforms, and its memory is included in the PS3, along with that console's bonkers Cell processor.The Elpida RAM comes in 512MB chips, and runs at a 9.6GB/s transfer rate, which is about six times standard DDR2-800. You can also forget your average double data rate - this stuff runs with an octal data rate of 600MHz to get to 4.8GHz. Crazy.Its manufacturers are touting it around as a good solution for a new wave of HDTVs, servers and workstations. Don't expect to see it showing up in your gaming rig anytime soon, however - production won't start until April 2008, and we can't see Intel being too keen to take another stab at a Rambus platform. µ
