Re: It's not just higher MHz. It's lower latency and higher bandwidth... Rambus latency is worse than PC100, by quite a bit. It's bandwidth lets it fill a cache line a little more quickly if the particular rambus chip being addressed is active. PC133, despite still having quite a bit less bandwidth, still fills a cache line more quickly than rambus, thanks to the head start its lower latency gives it. DDR has bandwidth equal to rambus at 200 and greater bandwidth at 266, still has much lower component latency, and costs far less to manufacture than rambus. VC can be added to PCXXX and DDR XXX and provides the same multiple open page benefits of rambus. Again, at far lower cost and double the component density. But as an AMD long, I applaud Intel's dogged determination to stick with rambus. :-) Keep it up, guys! Dan
