AMD Turion

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.

Turion X2 Ultra (codenamed Griffin) is the first processor family from AMD solely for the mobile platform, based on the Athlon 64 (K8 Revision G) architecture with some specific architectural enhancements similar to current Phenom processors aimed at lower power consumption and longer battery life.

The Turion Ultra processor was released as part of the "Puma" mobile platform in June 2008.

The Turion X2 Ultra is a dual-core processor fabricated on 65 nm technology using 300 mm SOI wafers.

By adjusting frequency and voltage during use, the processor can adapt to different workloads and help reduce power consumption.

[5] It also implements multiple on-die thermal sensors through integrated SMBUS (SB-TSI) interface (replaces and eliminates the thermal monitor circuit chip through SMBUS in its predecessors) with additional MEMHOT signal sent from embedded controller to the processor, and reduces memory temperature.

[6] AMD Fellow Maurice Steinman has said the cores are almost transistor-for-transistor identical to those found in the 65 nm Turion 64 X2 processors.

[citation needed] Turion II Ultra (codenamed Caspian) is the mobile version of the K10.5 architecture produced using 45 nm fabrication process, also known by its desktop variant Regor.

The two letters together designate a processor class, while the number represents a performance rating (PR).
