Somehow, I just can not picture a foundry agreement for a duration of only one quarter. If such an agreement has been struck, how IBM would benefit would be with a solid commitment to their own wafers being produced in bulk. Bulk production of SOI wafers by IBM would bring down foundry costs for other partners, increasing IBM's profits and/or lower the wafer cost to the partner. To insure that this comes about the agreement would have to be of fairly long duration, at least a year. Additionally, I would anticipate that IBM would gain the rights to fab mobile Thoroughbred (or 0.13-micron shrink of Palomino) processors under the IBM brand for internal use. For this reason it might be more accurate to describe this as a mobile Palomino rather than Thoroughbred. I have a feeling that Thoroughbred will, like Hammer, support SSE2, and like Northwood, have 512K L2 cache. The mobile processor fabbed by IBM would likely be a shrink of Palomino without SSE2 and with only 256K L2 cache. This type of an agreement would make sense for many reasons. One is the time that it takes to convert a bulk silicon design to SOI. The other is the historical impact of foundry agreements with IBM on their partners. And, from an historical perspective, this would be like licensing IBM to produce the Littlefoot K6 as AMD moves on to K6-2, which did AMD no harm. IBM could continue to produce under license and market the 0.13-micron SOI mobile Palomino indefinitely, while AMD moves on to the 0.13-micron SOI mobile Thoroughbred fabbed at Fab30.
