Afaik, originally there was no other difference between the H55 and the H57 than a new TurboMemory like technology and both chipsets were planned for a release. The H57 had that new technology, the H55 didn't. Then intel pushed the launch of that technology to a later date and cancelled the H57 chipset. But now suddenly there are H55 as well as H57 mobos showing up in the tech-news. Now that at the end H55 as well as H57 chipsets have become reality and that mentioned new technology has been pushed to a later date, what is the difference between the H55 and H57 chipsets?
