AMD is developing the next generation AMD Radeon HD 8000 graphics chip for launch in the second quarter of 2013 and we get new information about the platform, especially on high-end models.

Under the code name ‘Sea Island’, the AMD Radeon HD 8000 will be an update of the Graphics Core Next architecture, built on 28-nanometer process technology.

The latest information indicates a significant increase in stream processors and ROPs in the most powerful models in the series (Radeon HD 8970 and Radeon HD 8950) and a larger than previous models to accommodate an impressive number of transistors: 5100 million.

The core speed for both cards will be 1050 MHz, while memory speeds are listed in the 6000 and 5500 MHz. This will influence, the TDP will be of 260 and 210 watts respectively. The Radeon HD 8970 and Radeon HD 8950 include 3 GB of GDDR5 memory with 384-bit interface.

Also increase significantly the number of transistors values, frequencies or stream processors for high-midrange Radeon HD 8800 and Radeon HD 8700, probably the most interesting price / performance of the new generation of AMD Radeon dedicated graphics.

This was all regarding the AMD Radeon HD 8000 series upcoming high end graphics card, stay tuned for more information.
