AMD Turion 64 X2 (Taylor, Trinidad, Tyler) processors
Introduction: May 2006 (Taylor and Trinidad), May 2007 (Tyler)
Turion 64 X2 was AMD's 64-bit dual-core mobile CPU, intended to compete with Intel's Core and Core 2 CPUs. The Turion 64 X2 was launched on May 17, 2006, after several delays. These processors used Socket S1, and feature DDR2 memory. They also included AMD Virtualization Technology and more power-saving features.
The Taylor, Trinidad and Tyler cores
AMD first produced the Turion 64 X2 on IBM's 90 nm Silicon on insulator (SOI) process (cores with the Taylor codename). As of May 2007, they switched to a 65 nm Silicon-Germanium stressed process, which was achieved through the combined effort of IBM and AMD, with 40% improvement over comparable 65 nm processes. The earlier 90 nm devices were codenamed Taylor and Trinidad, while the newer 65 nm cores had codename Tyler.
