What generation is the GM45 chipset with GMA4500 graphics?

What generation is GM45 chipset? I was not able to figure it out. I've reported a bug against sandy bridge but GM45 with the GMA4500MHD graphics seems to not of the SB generation. I'm going to have to rename the bug. What name should I use?

ThinkPad T500

PS. I don't recall 4500 being mentioned in any Linux logs, glxinfo, dmesg etc. Just the chipset name.

GM45 is gen4. Sandy Bridge is gen6.
