NVidia chooses single-chip solution for its Clawhammer chipset. From xbitlabs: xbitlabs.com NVIDIA's Solution for ClawHammer! Posted 7/23/02 at 12:56 pm by Rat Together with the launching of nForce2 chipset, NVIDIA announced one more solution known under Crush K8 codename and intended for the future 64bit AMD ClawHammer CPUs. The presentation of the new chipset was carried out by the platform division director, Drew Henry. Once again NVIDIA introduced a solution, which doesn’t have anything in common with the competitor’s analogies, and moreover, looks very logical and technically complete. Let’s recall what should characterize the chipset North Bridge, namely its high-frequency part. These are the supported memory, the graphics interface (AGP and/or integrated graphics), and the bus connecting the chipset North and South Bridges (V-Link, MuTIOL). That’s it. And now you remember that in case of ClawHammer processors the memory controller is integrated into the processor die. So what do we have left? AGP and the bus between the bridges. And what do we then need high-frequency North Bridge if the AGP support could be implemented in the South Bridge (by the way, the AGP 8x frequency is only 66MHz)? Of course, this doesn’t eliminate the connection between the chipset and the CPU, but removes one chip from our equation, which reduces the system cost. As a result, NVIDIA got a chipset, which consists of only one south-eastern or south-western chip, while all the other companies took the good old way of introducing two-chip solutions. Of course, NVIDIA engineers had to sacrifice a few things for the sake of this beautiful solution. Crush K8 certainly has no integrated graphics core. To tell the truth, who needs it there? However, from the technological point of view the solution appeared simply excellent: simple, not expensive and functional. And what else does a mainstream system chipset need? Frankly speaking, I haven’t very often come across a chipset, which I really liked. Crush K8 seems to be this rare one :) As for the chipset specifications, it doesn’t make much sense to go into detail here. Evidently, Crush K8 will imply the features of the MCP-T South Bridge and will support AGP 8x interface. No doubt, that it will later acquire SerialATA150 support too. And that’s basically all it might need. Drew Henry hasn’t told the public about the schedule for mass supplies of the new Crush K8. We expect it to take place together with the launching of ClawHammer CPUs. Petz
