AMD's New Plans for Quad-Core and "4x4" Processors

We have a new microarchitecture under development and the first substantiation of that will be the quad-core to be launched in mid 2007,

said Dirk Meyer, AMD's president and chief operating officer. AMD is working on a new architecture, which includes L3 cache, 32-bit instruction fetch, dual 128-bit SSE data flow, dual 128-bit loads per cycle and "true quad-core" meaning it will contain four separate cores on a die. In the meantime, AMD has plans to release a chip for the enthusiast market called the 4x4, which links two dual-core processors using AMD's fast hypertransport link to get quad-core like performance. AMD has said that product will be promoted by the holidays in contradiction to the Core 2 Duo processors.
