AMD's branding team has decided to put some distance between Deneb Quad-core with 4x512KB L2 and 6MB L3 cache and upcoming Propus, Quad-core without L3 cache.

These are two different cores, as we were told before that Propus won't have just L3 cache disabled, it will be designed without L3 cache, but as well as Deneb it will have 4x512KB L2 cache per core.

Propus will therefore be introduced to the world as Athlon X4 600 generation and not as Phenom II, as many have hoped. We understand that AMD wants to differentiate Deneb from Propus but they could at least brand it as Athlon II as this is a completely new architecture compared to K8, architecture behind most of Athlon CPUs on the market.

Rana tri-core will also end up branded as Athlon X3 brand.
