After most of AMD's partners stated that they would not adopt the HD 7870 LE, based on a stripped version of the high-end 'Tahiti' GPU, it stayed rather quiet on AMD's latest mid-range card. Following Club 3D, PowerColor and VTX3D, Sapphire is the fourth manufacturer to introduce an HD 7870 LE card. The new Sapphire HD 7870 XT with Boost has 2 GB of GDDR5 memory.
Contrary to what its name may suggest, the card runs at reference clock frequencies. This means that the core is clocked at 925 MHz, which can be increased to 975 MHz through PowerTune. Like the other three HD 7870 LE cards, this model has 32 ROPs and a 256-bits interface. Although the rest of the specifications point at a stripped HD 7900 chip, the official site lists 1280 stream processors, instead of 1536.
The memory has an effective clock frequency of 6 GHz, also identical to the reference model. With the bundled Sapphire TRIXX-software, the card can be overclocked. The new graphics card is cooled by a dual-slot Vapor-X cooler with four heatpipes.
Sapphire's new graphics card has an HDMI 1.4 connector with 3D support, two mini-DisplayPort outputs and a dual-Link DVI port. Although a recommended price has not yet been revealed, the card is expected to release soon.
Update: Sapphire has confirmed that there has been an error in the specifications. The card does have 1536 stream processors and 96 TMUs, which makes it a Tahiti-GPU, as can be found in AMD's Radeon HD 7950 and HD 7970 cards.
