Although dual-core desktop processors from AMD are on the horizon, engineers there are still hard at work refining their single-core processor designs. The latest revision to the Athlon 64 core, internally code named "Venice", recently made it way onto the mass market, carrying a "Rev. E" moniker. With the Venice core, AMD has integrated SSE3 multimedia instruction sets into the Athlon 64, and have made some additions and enhancements to the integrated memory controller as well.
