AMD had some sort of an issue with Propus, which is basically a Deneb core with the L3 cache physically removed . This core was supposed to show up at some point in late Q1 or early Q2 but now, after months of delays they are getting ready to launch it in September.

Propus has an issue that it should have performance extremely close to Deneb and this will definitely be an issue for AMD. The good thing about it is that this might be one of the smallest quad cores around but with AMD's Quad core prices being as low as they are, there is not much space to make these CPU more affordable.

With 2.6 GHz Phenom II X4 with 4x512MB L2 and 4MB L3 cache selling for €122 we have to admit you can't go much lower than that.
