insane schrijft dat er bij ZDNET een artikeltje staat waarin Rambus geheugen wordt vergeleken met DDR-RAM. De conclusie is dat beide soorten Ram snel zijn maar dat de prijs van een Rimmetje gewoon te hoog is, iets wat wij natuurlijk al lang weten.
AMD is on the other side of the trench, occupied by DDR. Like Rambus, DDR doubles system memory bandwidth, thus increasing overall PC performance. Both memory technologies were developed to allow PC systems to keep up with the rapid increase in desktop PC processor clock speeds.
There will actually be two flavors of DDR to start. The first, PC 1600, will offer a bandwidth of 1.6GB per second, or twice as much as today's standard 100MHz SDRAM memory. The second kind, PC 2100, delivers 2.6GB per second of peak bandwidth. Rambus delivers 1.6GB of peak bandwidth, while the current peak bandwidth of SDRAM is 800MB per second.
"DDR, fundamentally, is a two-times improvement over SDRAM at the same clock speed," said Mark Kellogg, a senior member of the staff at IBM Microelectronics in Burlington, Vt.
