![]() #Fury x fp64 proHowever the GT3e should be more powerful in theory considering the Haswell CPU cores and Iris Pro graphics. That’s one reason why an A100 with a total of 432 Tensor Cores delivers up to 19.5 FP64 TFLOPS, more than double the performance of a Volta V100. That said, it is doubtful that Kaveri will ever excel at fp64 intensive work.Where fp32 is concerned, Kaveri outperforms Haswell GT2 igpu and ivy bridge. They support a larger matrix size 8x8x4, compared to 4x4x4 for Volta that lets users tackle tougher problems. If you have Win 8 you can optimize it through C++ and Iris Pro. Running the same code, optimized for AVX or FMA, on Haswell will grant better results. Kaveri's fp64 peak including both the CPU and GPU is 110 gflops. Not to mention that HSA and Mantle should open up more possibilities in the future. Because under GCN kaveri's gpu support fp64 under all APIs. However Kaveri is indeed a turning point for APUS. Also it seems that the do not support fp64 under Direct Compute at all. It apparently depends on a set extension (which is proprietary btw) cl_amd_fp64. AMD's Trinity and Richland does not have standards compliant fp64 under OpenCL. Sadly even on the AMD side of things, fp64 is a mess. According to a source of AnandTech the speed is roughly 1/4 compared to fp32. Problem is that Intel only enables fp64 for Direct Compute and NOT open CL, which is not the case with AMD. During the conversation Leo called the chip both “Fiji” and “Fury” and Ron did not blink, so we know that it is the correct name.As you can see the floating point 64 scenario is somewhat of a mess. KitGuru Says: It is hard to understand why AMD is not prepared to show “Fiji” to the Press. Image of AMD Radeon Fury X published by Johan Andersson Moreover, an image of the graphics card itself was recently published by Johan Andersson, technical director of Frostbite at Electronic Arts, in a Twitter post. Obviously, a static image of the product cannot reveal any performance details. The main intrigue about the AMD Radeon Fury X graphics board is its performance. The problem is, many aspects about the graphics board are already known: it has 4GB of memory, it has short printed circuit board, it requires two 8-pin PCI Express power connectors, it is power hungry (may consume up to 375W of power), it uses hybrid liquid cooling system, etc. The base frequency, not the turbo freq is. The benchmarks are per-cycle based and the peak is calculated in Gigaflops. Put it another way, the requirement for 8GB (or whatever) is in combination with the current, slower bandwidth.Īpparently, AMD wants to build the marketing impetus for the 16th of June, when the first reviews hit the Web, or the 24th, when the graphics cards hit the stores. AMD released that the fp64 capability is roughly 1/16th of its fp32 capability. Ron Myers assured that 4GB of high bandwidth memory is plenty for 4K gaming so it is not just a question of the amount of memory, but also the speed and bandwidth. #Fury x fp64 installHis question about the 4*1GB limit was side-stepped so it is unclear whether AMD could install 8GB of HBM if they choose. The Fury X was essentially overbuilt in this regard, so it’s easy to see why AMD wouldn’t need a larger CLLC. While it was impossible to take photos of the AMD Radeon Fury X, Leo tried to discuss some aspects of the flagship graphics card that only features 4GB of memory (compared to 12GB on Nvidia’s GeForce GTX Titan X). “No,” said Ron, and that was the end of that. “How about static without performance?” Leo asked. They both knew the other side of the Sapphire NDA door was the card Leo wanted to see, so Leo asked if he could see the card and take photos. They refused to give its name but the unnamed chip had four stacks of HBM so it was “Fiji”, no question.ĪMD is showing a running and apparently fully working version of “Fiji” to customers but not to the Press, so Leo asked Ron if he might relent. Ron is a big guy in every sense of the word and only slightly intimidating.Įarlier AMD waved a “Fiji” chip around on stage. At the Sapphire booth, Leo bumped into Ron Myers, Corporate Vice President of Corporate Marketing at AMD. He took the opportunity to head up to Sapphire, who were in a separate room, so he could say hello and grab a chair. Leo arrived at Nangang at 9am and was told the floor was closed to the Press until 9:30am. AMD “Fiji” graphics processing unit is held by Lisa Su, chief executive of AMD. But while the company did show its “Fiji” chip, it did not want to show the “Fury” card, reports Leo Waldock, a KitGuru editor, from Taipei. At a press conference at the Computex trade-show Advanced Micro Devices has officially demonstrated its first graphics processing unit with high bandwidth memory (HBM) code-named “Fiji”, which is set to power AMD’s next-generation flagship graphics card known unofficially as the Radeon Fury X. ![]()
