Centrino-Santa Rosa platform (2007)

The code-name Santa Rosa refers to the fourth-generation Centrino platform, which was released on Wednesday 9 May 2007.
The Santa Rosa platform consists of:
Processors - Socket P / Micro-FCBGA
an Intel Core 2 Duo (code-named Merom) second generation processor with 800 MT/s FSB, or
an Intel Core 2 Duo (code-named Penryn) 45nm processor with 800 MT/s FSB and SSE4.1, which will add 47 new instructions to SSSE3. It was scheduled for release in January 2008 for Santa Rosa Refresh platform, and
an Intel Mobile 965 Express chipset (code-named Crestline): GM965 with Intel's GMA X3100 graphics technology or PM965 with discrete graphics, and ICH8M southbridge, 800 MT/s front side bus with Dynamic Front Side Bus Switching to save power during low utilization, and
Intel Dynamic Acceleration (IDA), better Windows Vista Aero support.
RAM supported for DDR2-533 and DDR2-667 SO-DIMM.
EFI-compliant firmware, a successor to BIOS.
optional NAND flash-memory caching branded as Intel Turbo Memory (code-named Robson)
the Intel WiFi Link 4965AGN (a/b/g/draft-n) mini-PCIe Wi-Fi adapter (code-named Kedron).
Wireless-N technology boasts a 5X speed increase, along with a 2X greater coverage area, and supports 2.4 GHz and 5 GHz signal bands, with enough bandwidth for high definition audio and video streams.
The Santa Rosa platform comes with dynamic acceleration technology. It 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. Santa Rosa performs well as a mobile gaming platform due to its ability to switch between single threaded and multithreaded tasks.. Other power savings come from an Enhanced Sleep state where both the CPU cores and the chipset will power down.
The wireless chipset update was originally intended to include WWAN Internet access via HSDPA (3.5G), (code-named Windigo) co-developed with Nokia . After announcing a working partnership, both later retracted the deal citing the lack of a clear business case for the technology. Support for WiMAX (802.16) was originally scheduled for inclusion in Santa Rosa but appears to have been delayed until Montevina in 2008 .
The Santa Rosa platform is 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.
