Turion 64

Turion 64 is the brand name AMD applies to its 64-bit low-consumption ("mobile") processors codenamed "K8L". [ [http://www.theinquirer.net/default.aspx?article=37444 The Inquirer report] ] The Turion 64 and Turion 64 X2 processors compete with Intel's mobile processors, initially the "Pentium M" and currently the Intel Core and Intel Core 2 processors.

Earlier Turion 64 processors are compatible with AMD's Socket 754. The newer "Richmond" models are designed for AMD's Socket S1. They are equipped with 512 or 1024 KiB of L2 cache, a 64-bit single channel on-die memory controller, and an 800 MHz HyperTransport bus. Battery saving features, like "PowerNow!", are central to the marketing and usefulness of these CPUs.

Features

Turion 64 "Lancaster" (90 nm)

All models support:
* MMX
* SSE
* SSE2
* SSE3
* Enhanced 3DNow!
* NX bit
* AMD64 instruction set
* PowerNow!

Turion 64 "Richmond" (90 nm)

The models support the same features available in Lancaster, plus AMD Virtualization.

Model naming methodology

The model naming scheme does not make it obvious how to compare one Turion with another, or even an Athlon 64. The model name is two letters, a dash, and a two digit number (for example, ML-34). The two letters together designate a processor class, while the number represents a performance rating (PR). The first letter is M for single core processors and T for dual core Turion 64 X2 processors. The later in the alphabet that the second letter appears, the more the model has been designed for mobility (frugal power consumption). Take for instance, an MT-30 and an ML-34. Since the T in the MT-30 is later in the alphabet than the L in ML-34, the MT-30 consumes less power than the ML-34. But since 34 is greater than 30, the ML-34 is faster than the MT-30.
