PowerColor also announces ´Tahiti-LE' Radeon HD 7870 card

By , source: PowerColor, techPowerUp!


Yesterday, Club3D introduced the first graphics card based on AMD's stripped-down 'Tahiti LE' chip, in the form of the Club3D HD 7870 jokerCard. Although the official introduction date is November 27th, PowerColor has announced its own version of the card. There are persistent rumours that most partners won't adopt the GPU, as AMD doesn't offer a reference design for the card.

The new Tahiti LE is reportedly available in limited quantities only. The new chip is about 15% faster than Nvidia's GeForce GTX 660 card. With both Club3D and PowerColor having announced an HD 7870 based on the chip, we're getting a better idea of the final specifications of the graphics card. It's no coincidence that specifically these two manufacturers have shown their versions, as they are part of the same parent company TUL, to which VTX3D also belongs.PowerColor's graphics card is called PCS+ HD7870 Myst. Edition and has the same specifications as Club3D's jokerCard. This means that the GPU has 1536 enabled Stream Processors and a 256-bits memory interface. To compare: a full-fledged Tahiti chip has 2048 shader units and a 384-bits controller. The GPU is clocked at 925 MHz, with a 975 MHz Boost frequency. The 2 GB of GDDR5 memory has an effective speed of 6 GHz.

The PCS+ HD7870 Myst. Edition is compatible with DirectX 11.1 and CrossFireX. It has a DVI, HDMI and two Mini DisplayPort connectors. Two 6-pin PCI-e power connectors are required for the card. Unfortunately, a price has not yet been revealed. Given its competition though, it's likely to be similar to that of the GeForce GTX 660.
