Santa Rosa is a big deal for Intel. In addition to supporting Intel Core 2 processors (several new releases are planned; details below), Santa Rosa will offer the following improvements:

- An 800-MHz front-side bus (FSB) -- the previous FSB speed was 667 MHz -- with "Dynamic Front-Side Bus Switching" technology that is capable of underclocking the FSB during low CPU utilization to save power

- Intel's faster and more thermally efficient Mobile 965 Express chipset, with the GMA X3000 integrated mobile graphics part

- A new CPU socket known as Socket P that will permit the aforementioned 800MHz front-side bus speed; this will replace the current Socket M

- Much faster 802.11n Wi-Fi support (802.11a/b/g will also be supported) via a new wireless platform code-named "Kedron"
