The first pictures of three new Tonga GPU graphics cards have been shown and as so often before, the guys over at Videocardz got the first scoop. We’re being presented with a few shots of the Radeon R9 285 series with cards from Sapphire , XFX and HIS Digital.
The new R9 285 will use the Tonge Pro chips, so we can most likely expect Radeon R9 285X to be based on the Tonge XT chip soon. All three new cards are short reference cards, but with custom dual cooler solutions.
They use the XDMA Crossfire so there is no need for bridges (and the pins for them). Connection wise we see the basic AMD setup of 2x DVI, 1x HDMI and 1x DisplayPort.
The actual specifications are still mostly rumours and speculations. We do know that it will have 2GB GDDR5 memory on a 256 bit interface, but besides that we’ll have to wait a little bit more. More should be known very soon as the launch is said to be only 2 weeks away.
The core clock is said to be 918 MHz and the memory clock will be 1375 MHz (5500 MHz effective), and a bandwidth of 176 GB/s. The full Tonga chip itself has the same number of unified cores as the Tahiti, but we don’t know how many the R9 285 will have.
Thank you Videocardz for providing us with this information.
