According to Hot Hardware, Fiji will initially be available in both Pro and XT variants with the Fiji Pro dubbed “Fury” and Fiji XT being dubbed “Fury X”.
The standard Fury is slightly neutered compared to the Fury X, given its pared down stream processors, compute units, and texture mapping units. But when all is said and done, the garden variety Fury still touts single-precision floating point (SPFP) performance of 7.2 FLOPS compared to 5.6 TFLOPS for a Radeon R9 290X. That’s a roughly 29-percent performance improvement, which is nothing to scoff at in the graphics world.
The Fury X with its 4096 stream processors, 64 compute units, and 256 texture mapping units manages to deliver 8.6 TFLOPS, or a 54-percent increase over a Radeon R9 290X.
Both the Fury and Fury X dissipate heat via three axial fans. The water-cooled Fury X shares the same physical hardware specs as the air cooled Fury X, but will see its GPU clock increased by an unspecified amount, which should allow it to deliver slightly more than 8.6 TFLOPS.
What is looking sexy, for those who need to get out more, is AMD’s High Bandwidth Memory (HBM) interface, which is stacked vertically, decreasing the PCB footprint. It is integrated directly into the same package as the GPU/SoC, leading to further efficiencies, reduced latency and a blistering 100GB/sec of bandwidth per stack (4 stacks per card).
HBM is claimed to deliver three times the performance-per-watt of GDDR5 memory.
