AMD hints at dual GPU Radeon R9 Fury X2 graphics card (again)

0

CeBIT is coming next month, it might be possible in terms of timing. Anyway, on his Twitter account, Scott at AMD posted a photo with two FIJI GPUs in his hand, which my friends would suggest and point to the dual GPU Radeon R9 Fury X2.

This isn’t the first time AMD has teased it, let alone shown it. Even last summer they showed a prototype. A few weeks ago, the cards were apparently spotted and installed in at least one Falcon Northwest Tiki compact gaming desktop prototype as well as HTC Vive HMD. Falcon Northwest has already slipped that the Fiji-based dual GPU graphics card is very small and fits easily into a 4-inch thick Tiki.

Here is the photo that was shared:

The product will be small, really small. Which makes sense due to the HBM design, I mean look at Nano. Rumor has it that the Fiji dual GPU codenamed Gemini would have 8GB of HBM1 graphics memory with a whopping 8192 stream processors.

It has already been mentioned that the release of the Dual Fiji XT graphics card is scheduled for this year, probably in the second quarter. In fact, it was caught being shipped several times while showing up at an India-based courier. The code name that has been spotted is “Fiji Gemini”, and we have to mention here that “Gemini” has already been used by AMD to denote a dual GPU product. The previous photos however show two 8 pin PCI Express power connectors and therefore an allocation of up to 375 Watt (which honestly isn’t bad).

A Radeon Fury X pushes close to 8.6 TFLOPS of performance, meaning that a dual GPU version would deliver nearly 16 TFLOPs of single precision performance. And yes, a dual GPU Fiji would have 8GB of HBM1 graphics memory with a whopping 8192 stream processors. The PCB photo below is old, this is a first prototype / engineering samples from last summer.

It’s time for AMD to stop teasing, as it’s slowly getting labeled as vaporware. Hopefully it will be released soon.
