Fancified Shared Memory with a new name. Thanks ATI.
Alright, it's not exactly your typical shared memory solution. They're using the superior speed of PCI Express, combined with some on-card memory (hopefully at least half), and smart algorithms to try and get the textures on the card when they need to be there. The only problem is, now you're borrowing from my main memory, which isn't cheap when you're banking on the fast DDR/DDR2 memories of tomorrow. I'd rather spend the extra $30-50 on the card than have to buy another memory stick. Plus it could incur a performance hit on everything else, assuming it works properly and the graphics card doesn't see a hit. And what if the textures being used exceed on-card memory?
There are good and bad things about this, I just hope they leave it for lower end solutions only. I mean, it still beats the tar out of older shared memory designs. Either way, it is pretty interesting.
