HardOCP got their hands on some slides that outline AMD's upcoming quad-core technology that has recently taped out.
As expected, AMD's next-gen desktop technology will be first be showcased with in the yet-to-be announced Quad-Core Athlon 64 FX. At recent demonstrations of the AMD 4x4, Quad-Core has certainly been referenced as a desktop part. The slide below shows you the map of the upcoming Quad-Core Opteron as well as the Athlon 64 FX.
Certainly the highlights here are 65nm SOI which should bring power usage down even further, "enhanced" Instructions per Clock, and a totally redesigned cache system that introduces a shared L3 cache. And most importantly the Quad-Core design.
