AMD Fiji Officially Teased Via Photo On Twitter By Johann Andersson – Matches Previous Render


A picture of AMD's Fiji GPU , Radeon's Titan equivalent, has been published, officially, on twitter by no other than Johann Andersson. Andersson was the first independent developer to support AMD's Mantle and the brilliant engineer behind EA's Frostbite Engine that's leveraged across dozens of titles at the company. He called for low level APIs for ages and worked closely with AMD to bring this vision to life with Mantle. Thus AMD obviously saw it only fitting that he gets to be one of the first developers to receive a sample.

Fiji is purported to debut under a Titan equivalent branding scheme. Forgoing the traditional three digit nomenclature for something more exciting. The card has been referred to for the longest time as the R9 390X, mainly because that's the name that AMD has given its flagship single GPU graphics card with Hawaii in the 200 series.
However it's evident that AMD will debut a new brand name reserved only to its absolute best technology. And what other GPU is better suited to wear this crown other than Fiji ? The world's first GPU to feature next generation graphics memory technology, The Stacked 3D memory dubbed HBM which AMD revealed three days ago.

AMD's Fiji Finally Shown, Matches The Render Published Exclusively by Wccftech

So finally an actual photo of this fabled product has made its way to the web. And what a relief that this happened through official channels as we don't have to question its authenticity.
The astute among you will notice that the photo posted by Andersson matches the render that we had exclusively published a couple of weeks ago.

Now let's briefly talk about Fiji and it's new secret weapon, HBM.
HBM represents the revolutionary step that has been so badly needed in the evolution of graphics memory standards. The first generation of HBM promises to deliver 4.5X the bandwidth of GDDR5 and a staggering 16 times the bandwidth of DDR3.

Hynix-HBM-15Both GDDR5 and DDR3 are eclipsed by the 128 GB/s figure for first generation HBM.
The second generation promises to double the bandwidth by doubling the speed from 1Gbps to 2Gbps. While also quadrupling the memory capacity for 4-Hi stacks from 1GB to 4GB. HBM2 will be featured in AMD’s upcoming Arctic Islands graphics architecture with the “Greenland” flagship GPU.

In our technical deep dive on Fiji we were able to draw a rough estimate of the Fiji’s performance based on the core count and the clock speed. But as we can’t yet quantify the performance benefit from HBM without rigorous testing we left it out of the equation. Even without putting HBM into the equation the estimated performance of Fiji XT is quite phenomenal

Below are the unconfirmed/unofficial specifications for Fiji based on the R9 390X WCE rumor. and the SiSoft Sandra database leak.

Back to the news of the day. The eagle eyed among you will notice that the photo by Johann cleverly hides parts of the water cooling setup. The good news however is we have managed to confirm that reference air cooled versions of the card are definitely coming. We have also managed to confirm several parts of Fiji's specs. We'll be detailing these in an upcoming piece, so stay tuned.
