GeCube pair RV530s on same PCB, Gemini breaks cover
Dual chip Radeon X1600 has appeared on GeCube's stand, the Taiwanese vendor pairing two RV530s on the same PCB to create a single-board Crossfire product, codenamed Gemini. It's likely that two can be paired to do 4-chip Crossfire, too, sans master hardware on RD580.
There's bit more info on this configuration to come, but for now I'll leave you with just a pic.
