AMD seems to be making great progress with its upcoming Radeon HD 7000 series of graphics cards as the company has recently showcased a system powered by a next-generation Southern Islands GPU, to demonstrate that is on-track to deliver its first 28nm graphics chips by the end of this year.
The system presented during AMD's media event is based on a notebook development platform and uses a yet-unnamed GPU.
"Today, we provided an early look at our upcoming 28nm
next-gen notebook discrete GPU, driving Codemasters’ cutting-edge driving simulator, Dirt 3, demonstrating that we have working 28nm technology in house and already delivering a great gaming experience," reads an AMD
statement cited by Xbit Labs.
The company chose not to disclose any additional information about the Radeon HD 7000 chips, but it did state that its 28nm GPUs are fully functional and that they are getting ready to formally introduce them.
However, thanks to all the leaks that found their way to the Web, we now know that AMD's Radeon HD 7000
product family will use two different architectures.
The first solutions to arrive will use the VLIW4 shader arrangement introduced with the Radeon HD 6900 series, while 2012 will mark the introduction of the company's first graphics cards based on the Next Generation Core (NCG) architecture.
We talked about this new arch in detail in some of our previous articles, so we are not going to get into this now, but the key aspect of NCG is that it will improve the performance and functionality of GPGPU computing.
Together with NCG, it is rumored that AMD will also introduce support for XDR2 memory in its graphics cards. Developed by Rambus, this memory should be able to double the bandwidth of GDDR5 while using 30% less power.
