Santa Rosa platform (2007)

Santa Rosa platform (2007)

The code-name Santa Rosa refers to the fourth-generation Centrino platform, scheduled for release in May with the following features:[1]
second generation Intel Core 2 processor (code-named Merom) that uses Socket P
800 MT/s front side bus with Dynamic Front Side Bus Switching to save power during low utilization
Intel Mobile 965 Express chipset (code named Crestline) with Intel's GMA X3000 graphics technology
Intel PRO/Wireless 4965AGN IEEE 802.11 a/b/g/n mini-PCIe Wi-Fi adapter (code named Kedron)
NAND flash-memory caching branded as Turbo Memory (code-named Robson)
EFI, a successor to BIOS
Intel Dynamic Acceleration (IDA), better Windows Vista Aero support [1]
The chipset update was originally intended to include WWAN Internet access via HSDPA (code-named Windigo) codeveloped with Nokia [2][3]. After announcing a working partnership, both later retracted the deal citing the lack of a clear business case for the technology. [4]
Support for WiMAX (802.16) was originally scheduled for inclusion in Santa Rosa but appears to have been delayed until Montevina in 2008 [5]. There have however, been reports that WiMax may still be introduced in 2007.
Santa Rosa will feature an updated mobile Core 2 Duo microprocessor. Notably, the Front Side Bus speed has been increased to 800 MHz. The chipset can also dynamically change the FSB speed to save power.
Other power savings come from an Enhanced Sleep state where both the CPU cores and the chipset will power down.
Intel will also implement Dynamic Acceleration Technology with the Santa Rosa platform. This technology allows single threaded applications to execute faster. When a single threaded application is running the CPU can turn off one of the CPU cores and overclock the active core. In this way the CPU maintains the same Thermal Profile as it would when both cores are active. Many expect Santa Rosa to perform well as a mobile gaming platform due to its ability to switch between single threaded and multithreaded tasks.[6]
The Santa Rosa platform will be branded as "Centrino Pro" when combined with the enhanced security technologies Intel introduced with vPro and will be called Centrino Duo when they are not used.[7]
A refresh of the Santa Rosa platform scheduled for release in the 1st half of 2008 will upgrade to the 45nm Penryn Processor.
