On the desktop, the future is HyperTransport 3 and DDR 3. Chipsets will not shift to DirectX 10 until late 2007.
The key transition point, however, will come mid-2007. AMD has already said that's when its quad-core desktop CPUs will debut alongside new dual-care chips that, like the quadies, used HyperTransport 3 and incorporate Level 3 cache shared between the cores - 2MB of it, according to past leaks.
These two processor families - quad-core and dual-core - are believed to be codenamed 'Agena' and 'Kuma', respectively. The names 'Altair' and 'Antares' have also been mentioned in connection with these chips..
