Sapphire has announced a new R 270X graphics card, though rather than an ordinary reference model it has a custom card that carries 4 GB of GDDR5 memory.
The graphics card, which will be known as the R9-270X Dual-X 4 GB, features Sapphire's Dual-X cooler. This cooler carries two fans that blow air through an aluminum fin stack, to which heat is fed through a number of copper heat pipes. Additionally, the card has a custom PCB.
The memory on the card is clocked at an effective speed of 5.6 GHz, which when run over a 256-bit wide memory interface allows a bandwidth of 179 GB/s.
