Sapphireis working on a new beast of a graphics card, the Sapphire HD 7970 Toxic.

The card has 6 GB of memory in 24 GDDR5 memory chips, 12 on each side. To power the factory-overclocked 28 nm "Tahiti" GPU and 24 GDDR5 7 GT/s memory us a spicy VRM. Sapphire implemented an 8+3 phase power supply, that makes use of solid-state chokes, and International Rectifier DirectFETs. The VRM draws power from two 8-pin PCIe power connectors.

Sapphire implemented LEDs for each of the 8 vGPU phases, that gives you a real-time indication of their individual loading. These LEDs can be seen through a window on the top of the card.

The heatsink makes use of four 8 mm-thick nickel-plated copper heat pipes, as well as a vapor-chamber plate. It is ventilated by two 80 mm fans.

The card features out of the box clock speeds of 1150 MHz (core), and 1500 MHz (6.00 GHz GDDR5 effective) memory. It includes dual-BIOS, with a failsafe BIOS.

first bios - 1000/1450 Mhz
second bios - 1150/1500 Mhz

OCLab overclocked the card with its included cooler, to 1300 MHz (core) and 1900 MHz (memory), and put it through 3DMark 11. It scored P12463 points in performance preset.
