Apparently, the company Advanced Micro Devices is preparing its response to NVIDIA with its 28-nm chip architecture GM107 Maxwell, different decent performance together energy efficiency. According portal VideoCardz, currently being developed GPU codenamed Tonga can be the basis graphics card AMD Radeon R9 275X, which presumably would apply to decisions of the middle class and should be a worthy competitor to NVIDIA GeForce GTX 750 and GTX 750 Ti.
This in itself codename Tonga (Tonga) denotes a state in the Pacific Polynesia, continuing thus the practice of “geographic” names, which adheres to AMD. The GPU will be manufactured at rates 28-nm process technology, as well as GM107, and it would be based on modern architecture Graphics Core Next 2.0. Thus, we can rely on advanced technology PowerTune plus options Mantle, TrueAudio and possibly, XDMA CrossFire support, coupled with 2GB VRAM.
