AMD Radeon Fury and Fury X Specs Leaked, HBM-Powered Graphics On the Way 66
MojoKid writes: A fresh alleged leak of next AMD Fiji graphics info has just hit the web and there's an abundance of supposedly confirmed specifications for what will be AMD's most powerful graphics card to date. 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 garden variety Fury touts single-precision floating point (SPFP) performance of 7.2 TFLOPS compared to 5.6 TFLOPS for a bone stock Radeon R9 290X. That's a roughly 29-percent performance improvement. 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. The star of the show, however, will be AMD's High Bandwidth Memory (HBM) interface. Unlike traditional GDDR5 memory, HBM is stacked vertically, decreasing the PCB footprint required. It's also 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). On average HBM is said to deliver three times the performance-per-watt of GDDR5 memory. With that being said, the specs listed are by no means confirmed by AMD, yet. We shall find out soon enough during AMD's E3 press conference scheduled for June 16.
