AMD Radeon R9 Gemini only marginally faster than R9 295X2

Towards the end of 2015, AMD announced that their next dual-circuit graphics card Fiji was delayed until the early second quarter of 2016. The decision was attributed to a willingness to wait for the first VR headsets from Oculus and HTC, an area of use AMD believes the upcoming flagship .

During the event Virtual Reality Los Angeles (VRLA), the company therefore took the opportunity to demonstrate the graphics card, which is believed to be named Radeon R9 Gemini, in a compact chassis of a paltry 12 liters from American Falcon Northwest. Now Roy Taylor at AMD reveals further details.

We promised you we would take two of our highest end GPUs and put it inside that tiny box and if you go downstairs we actually have a demonstration of a dual GPU, 12 TeraFlops, fastest GPU solution in the world, inside of Tiki.

* The lowest clock frequency required to reach a theoretical computing power of 12 TFLOPS.

During a presentation, Taylor says that the graphics card used in the Tiki computer from Falcon Northwest has a computing power of 12 TFLOPS. This is considerably lower than the 16 TFLOPS company CEO Lisa Su trumpeted during the gaming fair E3 last summer, and means that on paper it is only slightly faster than the previous Radeon R9 295X2 with dual circuits Hawaii.

Instead of significantly higher performance, the graphics card can instead become much more energy efficient. Due to the low clock frequency required to reach 12 TFLOPS, the graphics card is believed to have a power consumption of 375 W, down from a full 500 W for the previous graphics card.

However, it can not be ruled out that AMD makes two graphics cards with dual circuits Fiji, one more energy efficient for compact builds and a higher clock aimed at the highest performance segment.
