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. It can operate as low as 250 MHz to conserve power during light use.Īdditionally, the processor features deep sleep state C3, deeper sleep state C4 (AltVID), and HyperTransport 3.0 up to 2.6 GHz, or up to 41.6 GB/s bandwidth per link at 16-bit link width and dynamic scaling of HT link width down to 0-bit ('disconnected') in both directions from and to the chipset for four different usage scenarios. By adjusting frequency and voltage during use, the processor can adapt to different workloads and help reduce power consumption. Indeed, in a matter of microseconds, the processor can switch to one of 8 frequency levels and one of 5 voltage levels.

This, along with multiple phase-locked loops (PLL), allows one core to alter its voltage and operating frequency independently of the other core, and independently of the northbridge. The Turion X2 Ultra processor, unlike earlier Turions, implements three voltage planes: one for the northbridge and one for each core. Clock rates range from 2.0 GHz to 2.4 GHz, and thermal design power (TDP) range from 32 watts to 35 watts. This is double the L2 cache found on the Turion 64 X2 processor. Each processor core comes with 1 MiB L2 cache for a total of 2 MiB L2 cache for the entire processor. It supports DDR2-800 SO-DIMMs and features a DRAM prefetcher to improve performance and a mobile-enhanced northbridge (memory controller, HyperTransport controller, and crossbar switch). The Turion X2 Ultra is a dual-core processor fabricated on 65 nm technology using 300 mm SOI wafers. The Turion Ultra processor was released as part of the ' Puma' mobile platform in June 2008. 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.
