In a bid to capture market share in the crucial Chinese Lunar New Year shopping season across the Greater China region, Sapphire launched a new graphics card occupying a price-point most tempting to value-conscious buyers, the Radeon HD 7770 Vapor-X Black Diamond. Simply put, it's a Radeon HD 7770 GHz Edition card with an advanced vapor-chamber-based cooler strapped on to it, with some groovy black styling dropped in; all of which shouldn't cost Sapphire much, but ups product presentation greatly. It is a slight variation of the Vapor-X OC found in western markets. The Sapphire HD 7770 Vapor-X Black Diamond uses a Vapor-X cooler which uses a vapor-chamber plate and two 8 mm-thick copper heat pipes to draw heat from the GPU, and conduct it to a dense aluminum fin stack, which is ventilated by a pair of 80 mm spinners. Underneath it is a custom-design PCB that's dressed in black, and uses Sapphire's noise-free chokes. The card sticks to AMD reference clock speeds of 1000 MHz core and 1250 MHz (5.00 GHz GDDR5-effective) memory. It packs 1 GB of GDDR5 memory across a 128-bit wide memory interface. Power is drawn from a single 6-pin PCIe connector. Display outputs include two DVI, and one each of DisplayPort and HDMI. This card is only available in China.
