Yes, somewhat ironic isn't it. Of course, the evil step sister of granularity is max mem. Here Rambus is in deep trouble since the largest number of Rdrams that can go on a channel is 32 by hard, architectural limit. Since 128MBit chips are the largest that are remotely economical to produce today due to Rdram die penalty this means that 512MByte is max mem for Camino. Not good for a highend machine. Also, 840 will have 1GByte max mem which is not good for a workstation. The 1GB limit of the 840 is probably worse than the 512MB limit of the 820, given the target markets. The current 'workstation' chipset, the GX (which is just a minor tweak of the BX), supports 2GB with memory you can buy today. BX/GX support 4 DIMMs (8 memory banks), up to 32 SDRAMs per DIMM (registered DIMMs). It's weird that Rambus designed in a hard limit of 32, rather than letting the limit be set purely by electricals. Oh well, after last week I guess it doesn't matter.
