<I believe someone here posted that the Alpha 21364 will have that kind of controller also> It's true. Compaq/Digital will integrate four DRDRAM controllers into one 21364 processor die, for a total memory bandwidth of 6.4 GB/sec, almost two-and-a-half times more than that of the 21264 (which is 2.66 GB/sec). Microprocessor Report has an excellent article on it, along with a theoretical 16-way Alpha system which has all the processors interconnected in a 4x4 square mesh pattern. So for those who think DRDRAM is an Intel-only solution, better think again. Tenchusatsu

Cirruslvr, Re <RAMBUS> What I've heard at the "pool" that the RAMBUS testing in systems revealed a design flaw - a sort of race condition in some situations. Therefore all licensed cores from RAMBUS have this flaw, including Intel controllers. I guess Elmer was right about difficulties in testability, so the flaw was discovered at very late stages in system-level testing. This would explain the desperate attempts to revive the project by lowering RAMBUS frequencies drastically. I suspect it will not help much.
