AMD's monstrous new FirePro S9300 X2 pro graphics card packs a pair of Fiji GPUs
AMD怪兽FirePro S9300 X2有两颗Fiji GPU
http://www.pcworld.com/article/3 ... st-monster-gpu.html
FirePro S9300 X2周四发布，是AMD现在第二快的显卡。产品定位在服务器和超级计算上的图像加速和科学应用。
FirePro S9300 X2是为Radeon Pro Duo而设计的。拥有两颗斐济核心。最大单精度浮点13.9T，拥有8GB HBM显存TDP是300瓦。
Nvidia依靠使用CUDA单元进行的high performance computing (HPC) 高性能计算占据了不少超算市场，AMD也打算追赶。
AMD希望OpenCL和GPUOpen能使HPC能从CUDA的代码转换过来能用在AMD新卡上。
但是何时出货以及价格多少AMD并没有表明。
AMD is releasing one monster graphics card after another as its GPU speed battle with Nvidia heats up.
The company’s FirePro S9300 X2, announced Thursday, is AMD’s second-fastest graphics card to date. The product is targeted at servers and supercomputers, where GPUs are used to speed up visual and scientific applications.
The new FirePro delivers a maximum single-precision performance of 13.9 teraflops. That’s shy of the 16 teraflop performance provided by the recently announced Radeon Pro Duo, a gaming GPU that AMD claims offers the highest performance of any single graphics card.
The FirePro S9300 X2 has the design of the Radeon Pro Duo. It has two GPUs based on the Fiji architecture and packed into one graphics card. That doubles the performance of the GPU. The FirePro draws 300 watts of power.
Memory and bandwidth enhancements also improve the FirePro’s performance. It has 8GB of HBM (High-Bandwidth Memory), which is significantly faster than the older GDDR5 memory. HBM also consumes less space and is more power-efficient.
The new FirePro is AMD’s latest salvo on Nvidia, whose Titan X, with a single GPU, delivers peak performance of 7 teraflops.
AMD may have a technological advantage in GPUs right now, but Nvidia isn’t far behind. Nvidia is expected to announce faster GPU technologies at its GPU Technology Conference next week. The technology enhancements could include a new GPU architecture, advanced memory and faster throughput mechanisms.
AMD later this year will announce graphics improvements of its own with GPUs based on its upcoming Polaris architecture, which will further intensify the graphics battle.
At this point, Nvidia holds a larger market share in standalone graphics cards, while AMD’s share is declining. Nvidia had 74 percent of the standalone GPU market in the fourth quarter, up from 72 percent in the year-ago quarter, according to Mercury Research. AMD’s market share was 26 percent, down from 28 percent a year ago.
Despite its technology achievements, AMD has failed to make a dent in supercomputing, where Nvidia is far ahead. Some of the world’s fastest computers use Nvidia’s GPUs, and AMD is trying to catch up.
The importance of accelerators like GPUs has grown in supercomputing. GPUs typically take code and break it down in parallel over thousands of cores to process a task or calculate an equation more quickly. Nvidia’s success in high performance computing (HPC) has come partly with its proprietary CUDA parallel programming framework, which has locked supercomputers to the company’s GPUs.
AMD has been relying on the open-source OpenCL parallel programming framework, and hopes to make HPC coding easier with GPUOpen, which are low-level APIs, so developers can take advantage of parallel computing features on the FirePro S9300 X2.
It usually takes researchers and scientists a while to modernize code to take full advantage of the newer GPUs, so AMD will need to aggressively drive change among the HPC community. AMD is offering tools so code can easily switch from CUDA to OpenCL or GPUOpen.
Pricing and availability for the FirePro S9300 X2 was not immediately provided by AMD.
