If the PS3 does make an appearance at E3 2005, as promised by Kuturagi, it is likely to be with reduced memory, according to news filtering through from the Rambus Developer Conference in Japan. Reports from PC Watch have suggested that Sony is replacing the 512 MB XDR DRAM chip originally planned for inclusion with a smaller 256 MB XDR DRAM chip. There could be several feasible explanations for this move, but Sony has declined to offer a full response as yet.
Optimistic onlookers could - and have - suggested that the reduced capacity of the DRAM chip is because the PS3’s memory bandwidth will be increased from 25.6 GB/Sec to 51.2 GB/Sec. This would mean that the Cell chip takes on more of the work, permitting this budget-friendly memory reduction.
Alternatively, the move is entirely budget-orientated. Early estimates of the likely and necessary cost of the PS3 have been rather lofty so far. Sony will inevitably be seeking to reduce costs, and this would be one obvious way to do that. However, if the PS3 is to make a late entry into the next-gen fray, it will need all the power it can harness; so, for Sony’s sake, let’s hope this isn’t a case of short-sighted, face-spiting, nose-cutting-off type behaviour.
