A quote from the article:
Last week AMD introduced the complete new line up of the Radeon R7/R9 300-series. However, all these new models are based on existing technology and GPUs. Today AMD is presenting their newest top end model based on a completely new chip. In our review we put the Fiji-based card through its paces.AMD Radeon R9 Fury X review: AMD's new flag ship graphics card @ Hardware.Info
Fiji is a massive chip, with more than 8 billion transistors and 4096 stream processors the GPU is even larger than AMD's fastest chip to date, the Hawaii chip found in the Radeon R9 290(X) and 390(X). The really special feature of the new GPU however is not its size, but the type of memory it uses. The Fury is the world's first graphics card that is using High Bandwidth Memory, a new memory technology that will not only allow for much higher throughput speeds, but also will make it possible to produce (much) smaller graphics cards.
