According to this review:http://www.rage3d.com/previews/mobility9600/?page=4
" The Radeon 9600 Pro will have three distinct features: OverDrive, GDDR2-M, and higher clock speeds. Gaming enthusiasts will definitely want the Pro edition."
Then about the GDDR2-M memory:
"GDDR2-M is basically GDDR2 memory that has been repurposed to run cooler, more efficient, and use less power. Ideal for the mobile market.
* 2.5 V Core power supply
* 1.8V I/O power supply
* VSSQ pull Down Self terminate inputs and outputs (ODT)
* Data Inversion support for both Reads and Writes
* Clock frequency: 300-450 MHz(DDR600-900) or above
They tested M10 NON-pro version (seen next pages of the review) which was running at 350MHz core/300MHz memory speeds.
Also see here:http://www6.tomshardware.com/mobile/...nvidia-01.htmlhttp://www6.tomshardware.com/mobile/...nvidia-02.html
So the non-pro version has maximum memory speed of 300MHz. The Pro version should run at memory clock about 350MHz.
"Equally import is the fact that by using GDDR-2 memory, the MR9600's memory clock of 284MHz gets a 40% boost compared to the MR9000. A Pro version of the MR9600 is due out this summer with a 350MHz memory clock – a 75% increase. Coupling the memory clock with a128-bit memory interface, the MR9600 will have peak memory bandwidth of 11.2GB/sec."
So unless you run the Sager at 350MHz memry clock or show in some way that the GPU is "overdriving" you have no proof that it is the Pro.
