AMD's E3 PCGaming event in which the company's launching the 300 series is only seconds away, and the presentation has already been leaked. It includes both the AMD Radeon 300 series and the infamous Fiji GPU powering the Fury series of graphics cards.

Fiji is the really exciting addition to the Radeon GPU stack. It's the first GPU in the world featuring stacked 3D memory. Called High Bandwidth Memory, or HBM for short. This new memory standard picks up from where GDDR5 left off and is and features entirely new technology co-developed by SK Hynix and AMD.

AMD Radeon 300 Series And Fiji E3 Presentation Leaked

Needless to say these newcomers will be AMD’s fastest and most advanced graphics chips to date. The Fiji GPU, both the XT and Pro variants, form the foundation of AMD’s new ultra enthusiast “Fury” brand. There are several reasons as to why AMD decided to resurrect the “Fury” brand name with Fiji. Chief among which is that with Fiji AMD will be introducing the world’s first GPU featuring 3D stacked High Bandwidth Memory, otherwise known as HBM. Another reason is the sheer performance of the chip, which AMD has proclaimed to be the fastest in the world. To crown these achievements AMD decided that a simple numerical product name will not do this chip justice and thus will be bringing back the Fury brand name.
