Dual-GPU graphics cards on the ATI side are hardly a new invention, but according to a report by HKEPC, HIS plans to spice things up a little by introducing such a card for ATI's upcoming 80 nm graphics cores. HKEPC says the HIS X1600 Gemini is currently being tested with ATI's RV530 Pro—a.ka. Radeon X1600 Pro—graphics processor, but that HIS developed the card with upcoming RV560 and RV570 GPUs in mind.
If earlier reports about ATI's 80 nm lineup are accurate, the RV570 will be an X1900-class GPU with 36 pixel shader processors, 12 texture units, and a 256-bit memory bus. Meanwhile, the RV560 will launch under a new X1700 moniker, and it will sport 24 pixel shader processors, eight texture units, and a 128-bit memory bus.
According to HKEPC, the HIS Gemini card mirrors NVIDIA's GeForce 7950 GX2 in that it uses an onboard bridge chip to allow both its GPUs to share the same PCI Express interface. Dubbed PLX PEX8532, this bridge is said to support up to eight GPUs via 32 PCI-E lanes, all the while only drawing up to 7.38 W of power. HKEPC doesn't say whether the card will work in non-CrossFire-compatible motherboards. However, the site quotes HIS Marketing Manager Peter Yeung as saying support for ATI's GPU-accelerated physics implementation will be included so that one of the two GPUs can handle graphics while the other takes care of physics.
