Next-generation chipsets from AMD for the mobile platform will feature HyperFlash, a flash memory technology similar to Intel's turbo cache memory:
Intel has introduced its turbo cache memory earlier this year and sells it to notebook manufacturers at close to $20 a GB if not even less these days and this memory can really boost performance on Santa Rosa notebooks, especially if you have 512MB or 1GB RAM. Adding an additional 1GB turbo cache usually boost the system performance, especially with memory greedy Vista.
As AMD learned that this is the way to go, its own SB700 Southbridge will be able to support flash memory on the desktop and notebook side. This comes at some point in 2008 and we’ve seen a lot of notebooks with AMD chips inside and despite its inferior performance and battery life, a lot of price driven customers are getting AMD notebooks.
