AMD’s HD6870 has risen in popularity in recent months, as prices have continued to drop. Today in the UK you can pick up a Sapphire 1GB HD6870 for £135 inc vat, making an ideal, low cost purchase for gaming at 1080p. Today we are looking at a heavily modified card from Sapphire which is supplied with a proprietary two fan cooling system and custom PCB design.
Sapphire have been making modified graphics cards for as long as I can remember, but we are particularly interested in this card today as they have increased the size of the fan, and added an extra one for good measure. The card is equipped with 1120 stream processors, 56 texture processing units and clock speeds have been increased to 920mhz core and 1050mhz for the 1GB of GDDR5 memory.
The new card has dual 90mm fans with thin impellers to move the same amount of air, but with 10% lower rotation speeds than the standard design. This should not only reduce noise, but with the special dust sealed bearings they will have a longer life span.Sapphire HD6870 Dual Fan Overclock Edition Review (with Dirt 3),
