Sapphire Launches Radeon HD 7870 Toxic Graphics Card
Sapphire launched its Radeon HD 7870 Toxic 2 GB graphics card, based on the 28 nm "Tahiti LE" Pitcairn silicon. The card uses a swanky new dual-fan cooler that features a design unlike anything launched by Sapphire so far. It uses a single aluminum fin stack that spans the entire length of the card, to which heat is conveyed by four 8 mm-thick heat pipes that make direct contact with the large die. The card also features a back-plate. It appears to use a high-grade VRM with DirectFETs. The HD 7870 Toxic from Sapphire packs 2 GB of GDDR5 memory across a 256-bit wide memory interface. According to our Sapphire contact, the card is exclusive to the Chinese market.Update 28/11
