Yes, iMac11,2 (21.5-inch, Mid 2010) has 3 models in everymac.com, - Core i3 3.06 GHz, Radeon HD 4670, 256M vram - Core i3 3.2 GHz, Radeon HD 5670, 512M vram - Core i5 3.6 GHz, Radeon HD 5670, 512M vram These Radeons might differ. Marcus's 3.06 has product id 0x9488, which in drm/drm_pciids.h is CHIP_RV730. An iMac11,2 3.2 in OpenBSD's dmesg collection has id 0x68c0, which is CHIP_REDWOOD. An iMac probably has its original graphics card. A Mac tower can swap cards; a PowerMac7,3 might have radeon or nvidia. --gkoehler
