Matt Skynner CVP and General Manager of AMD's GPU and APU products touted the company's upcoming flagship Fury X as the world's fastest GPU. As he proclaimed today at the company's Computex press conference that "HBM enables us to build the fastest GPU in the world" when referring to Fiji, reports Hardwareluxx .

Interestingly Hardwareluxx reported yesterday that AMD's upcoming Fiji XT powered flagship, dubbed Fury X, in its current state may not be as fast as Nvidia's Titan X and GTX 980 Ti, due to some peculiarities around the immature nature of the drivers for the yet unreleased Fiji GPU and the fact that AMD is still tweaking the BIOS settings for the Radeon Fury based cards which are based on it.

Hardwareluxx cited internal source's but we have no reason to discount their claims. It is actually not uncommon for graphics cards to initially perform below expectations before their launch. That is while their firmware and drivers are brought up to pace to realize the full potential of the silicon.

Going by Skynner's remarks, it seems that AMD is quite confident in its ability to bring Fiji's performance up to snuff before the official June 16th launch date.

How Fast Can Radeon's Flagship Fury X Actually Be ?

It's a very bold claim to proclaim Fiji as the world's fastest GPU. And as such we're going to investigate that claim through the magical tool that is math.

A lot of sites have speculated on how Fiji XT would perform in comparison to the GTX Titan X and its younger sibling the GTX 980 Ti. We have to make it plain that it’s extremely difficult to predict how the chip would exactly perform without rigorous testing. This is because HBM represents a wild card in the performance equation for FIji. We can’t yet quantify how much of a performance improvement having this much memory bandwidth would yield.

However we can easily attempt to draw a conservative estimate of Fiji's performance based on the leaked specifications of the chip.
