Turion 64 is the brand name AMD applies to its 64-bit low-power (mobile) processors. These processors, including the Turion 64 X2 processors, compete with Intel's mobile processors, initially the Pentium M and currently both the Intel Core processors.

Turion 64 processors (but not Turion 64 X2 processors) are compatible with AMD's Socket 754 and are equipped with 512 or 1024 KiB of L2 cache, a 64-bit single channel on-die memory controller, and an 800MHz HyperTransport bus. Battery saving features, like PowerNow! (Cool'n'Quiet), are central to the marketing and usefulness of these CPUs.

Model naming methodology

---

The model naming scheme does not make it obvious how to compare one Turion with another Turion, or even an Athlon 64. The model name is two letters, a dash, and a two digits number (for example, ML-34). The two letters together designate a processor class, while the number represents a PR rating. 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.
