You can find some tests to show the different performances between upcoming Intel Core 2 Duo T9400 and Core 2 Extreme X9100 based on Centrino 2 (Montevina) platform and current Intel Core 2 Extreme X9000 (overclocked and standard forms) and Core 2 Duo T9300 based on Santa Rosa Refresh platform.
Also, there is a first benchmark that has compared the current integrated Intel GMA X3100 graphics used in Santa Rosa Refresh platform with upcoming integrated GMA X4500 used in upcoming Centrino 2 platform.
Additionally, "the GMA X4500 Graphic Chipset supports DirectX 10 and Shader Model 4.0. There is a 100% increase over the existing GMA X3100".
All these tests have been tried by notebookjournal.de.
