Sapphire HD 6850 TOXICThe second Sapphire Radeon HD 6850 is part of its TOXIC range. It is overclocked at 820/1100 MHz instead of 775/1000 MHz, increases of 6% and 10% for the GPU and memory repectively. It’s on sale at €170.
Sapphire has gone for the Radeon HD 6870 reference PCB for the Radeon HD 6850 TOXIC. It’s longer, 24cm, and two 6-pin power connectors are required. There are four power phases and they’re all used.
The cooler used is a low cost verion of the Radeon HD 6870 reference cooler. Its architecture is identical: aluminium radiator with 3 heatpipes and fan. Sapphire have however reworked the frame design and replaced the copper base with an aluminium one with a copper insert. There’s a plate covering the PCB and it’s in contact with the memory modules as well as the sensitive power stage components.
Sapphire delivers its card with a CD for drivers, an installation guide, a Sapphire Select Club access card, a DVI to VGA adaptor, a small CrossFire connector and a molex to 6-pin PCI Express power supply cable convertor.
Sapphire guarantees this model for two years.

Both the GPU and power stage on the Radeon HD 6850 TOXIC are very well cooled.
Temperature and noise readings
These readings confirm that the card is well cooled and that a good part of the air is extracted from the casing. Although the noise in load is lower than the basic Sapphire card, the TOXIC is still louder than other models.
With the Radeon HD 6850 TOXIC, Sapphire is marketing a factory overclocked model at the price most other manufacturers are charging for their basic models. It has a big power stage which will prevent overheating during extreme overclocking, but it does get a little noisy in load.
