AMD Turion is the brand name AMD applies to its x86-64 low-power consumption (mobile) processors codenamed K8L. The Turion 64 and Turion 64 X2/Ultra processors compete with Intel's mobile processors, initially the Pentium M and the Intel Core and Intel Core 2 processors.
Earliest Turion 64 processors are plugged into AMD's Socket 754. They are equipped with 512 or 1024 KiB of L2 cache, a 64-bit single channel on-die DDR-400 memory controller, and an 800 MHz HyperTransport bus. Battery saving features, like PowerNow!, are central to the marketing and usefulness of these CPUs. The newer "Richmond" models are designed for AMD's Socket S1 and have a double-channel DDR2 controller.
Turion 64 X2 is 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 use Socket S1 and feature DDR2 memory. They also include AMD Virtualization Technology and more power-saving features.
The earlier 90 nm devices were codenamed Taylor and Trinidad, while the newer 65 nm cores have codename Tyler.
