    XDR 2 Rambus Memory?


    XDR 2 Memory


    I still remember when this article came out in 2011: AMD Radeon HD 7900 to Utilize New XDR2 Rambus Memory

    So what happened? Why isn't XDR 2 memory out by now? Why aren't GPU makers like NVidia using it for their graphics cards?

    I'm guessing XDR2 memory was just too expensive? That never stopped NVidia though - their Titan GPU is $1,000 & even the 780 is $650 (which is ridiculously over-priced when the 700 series is just a revamped 600 series) - what's an extra $100 (guessing) for killer XDR2 memory that's twice as fast as DDR5?

    I'm curious to find out if Maxwell or at least Volta GPU's will include XDR2?

    The XBox One should've had XDR2 but, they dropped the ball soooo bad that they went backwards with DDR3 instead of todays standard of DDR5. What's up with that?

    From the link you sent

    "As a fabless semiconductor company, Rambus only produces a design; it must make deals with memory manufacturers to produce XDR2 DRAM chips, and there has been a notable lack of interest in doing so"

    Sounds like that's the issue, no manufacture seemed up to it, or if they did, would probably cost A LOT. Memory does make a difference in framerate but nowhere as close to a GPU clockrate, Doubling the memory speed is not going to make a substantial difference. My assumption is they saw all the money and trouble in this with the minimal return on investment and decided to not go with it.

    I think it should be reworded as...

    Who would want to deal with them? They have just as sour a taste as SCO.

    I'll skip any hardware with Rambus designs in them if I can. Was disappointed to lean they'd infected the PS3.

    Because rambus puts out pretty graphs like that showing how fast their stuff is supposed to be, then in the real world it performs no better or even worse than the competition. See P4 era, and everything else that had their crap attached to it.
