I read (also that epox is releasing 8rda3+ or something, better 400mhz support Vdd adjust, SATA raid, dual lan.)

AMD, nVidia, x86-64 and RAMbus?! posted by Áedán
According to a recent press release by AMD, the next generation of x86-64 chips will feature a new embedded memory controller. AMD has apparently recognised that the new 64bit core will require more memory bandwidth than previously thought. In a cross-licensing deal, AMD has obtained rights to use nVidia's Dynamic Adaptive Speculative Preprocessor (DASP), as well as nVidia's DualChannel memory controller. Also, in a surprise move, AMD has licensed rights to use RAMBus Inc's memory bus technology.
We managed to track down an AMD product manager from AMD Europe, who told us this:
"Although it may sound surpising, we have found that modifications to [nVidia's] DASP and DualChannel controllers allow us to overcome the biggest problem with RAMBus - That of latency. DASP predicts the next few fetches that the processor will make and starts the fetch process from the RAMBus memory. This way we obtain amazing bandwidth through to main memory. Couple this with the high speed hyperlinks between x86-64 processor, we're going to be showing Intel the way forward for SMP machines."
