Sapphire has shown off its Dual HD2600XT just days after GeCube unveild its Gemini.
Sapphire's dual card uses RV630 A15 silicone, clocked at 800MHz and paired up with 1GB of 1.2ns GDDR3 memory, clocked at 1600.
The PCB is about one third larger than the one used for the standard HD2600XT, and it also has two 6 pin power connectors. Needless to say it's a dual slot card.
As we've mentioned before, you'll need Catalyst 7.9 to utilize the second core.
According to pcnoline, the performance is not that great, you can check out the original report (in Chinese) here, or you can take a peek at some pictures at OCworkbench, here.
