Gemini 1.6 (single core, no support for HT), Gemini 1.7 (HT supported), Gemini 2.0 (SMP with RAMDISK only and HT). Gemini 1.6 and 1.7 is based on the Rm9000 while the Gemini 2.0 is based on the Rm9000x2 thank you so much
Clock rates of Titan can go upto 1.2 Ghz. Titan is based on Rm9000x2 (also called GL internally)
