Associate put some fresh rumors about the upcoming graphic updates from AMD. Soon based on Graphics Core Next architecture promise to appear three new version of the GPU: Iceland, Tonga and Hawaii XTX. Initially it was thought that the GPU Iceland is coming to replace GPU Hawaii. Now Associate is inclined to assume that Iceland - GPU is average performance. Moreover, this graphics processor for notebook graphics cards (modules), which subsequently will be allowed to register
as desktop systems as discrete adapters. In some ways, Iceland could become a competitor to NVIDIA Maxwell GM107 .
Tonga graphics processor at its core - is the core of Tahiti with a 256-bit memory bus. Processors will not replace Tonga and Tahiti are intended to supplement line of video cards AMD with new models.
Processor Hawaii XTX, who attributed the 3072 stream processors - extended portion GPU Hawaii, in fact, promises to be just an overclocked version of Hawaii XT and will be released under the name Radeon R9 295X.
Now something new. According to our colleagues, GCN architecture soon learn some new extensions. . New improvement called UAV Ordering (Unordered Access View Ordering). Software technology AMD UAV Ordering akin to expand Intel PixelSync (HD Graphics), which allows programmers to combine hardware partially transparent pixels without having to perform time-consuming sorting operation. All this will enable a more realistic display such phenomena and things like smoke, regular structures
- hair, grills, foliage, windows and the like. The picture will become more beautiful, and artifacts will be less (below example of PixelSync).
GCN also updated at the hardware level will be supported technology Fast Conservative Rasterization. There is nothing new, but the hardware implementation promises to speed up image processing, for which today meets this software AMD, as TressFX.
Finally, the site AnandTech shared interesting screenshot. In the picture on the development partner AMD GPUs - the company Synapse Design - two new GPU, one of which has an area of over 500 sq. mm crystal, and the second - more than 350 square meters. mm. The final decision may be Tonga. Both solutions will be produced using 28nm process technology at the facilities of TSMC, then they will, most likely, at the turn of the third and fourth quarters of this year.
