结合CPU和GPU的服务器芯,将充分利用GPU浮点运算等优势

AMD成为在服务器超过十年前英特尔构成了严重威胁,但经过一系列的失误和糟糕的芯片,该公司的服务器业务是命悬一线上。

现在,AMD正在重新启动其服务器芯片业务与即将推出的禅CPU,这也将在PC上使用。AMD公司获得创意禅宗,并考虑合并具有高性能GPU的CPU来创建一个大型芯片的高性能任务。

“公平地说,我们相信我们能够与高性能GPU结合了高性能的CPU,”AMD公司首席执行官Lisa Su表示,周四财报电话会议上说。

苏的评论是为了响应是否AMD最终将基于即将推出的维加架构成一个大的芯片企业服务器和超级计算GPU的结合其禅CPU的问题。

“很明显,它会来的时候,”苏说。“这也正是两者结合的技术使得有很大的意义的领域。”

这不会是第一次AMD已经建立了一个大型的芯片。它已经结合上进行按订单生产芯片的Xbox一个和PlayStation 4游戏机功能齐全的CPU和GPU。5十亿晶体管的Xbox一个芯片采用八核CPU AMD代号为捷豹和Radeon图形处理器。

GPU是被用作一些世界上最快的计算机用于如天气建模,经济预测任务的协处理器,和武器的设计。他们还在为深学习任务的数据中心所使用的谷歌。Nvidia已经垄断了超级计算领域,而AMD已经与FirePro的高性能GPU的挣扎。

但是,AMD的集成大型芯片将是独一无二的。NVIDIA公司高性能的GPU,但缺乏一个CPU。英特尔的处理器占据主导地位的服务器,但它不提供GPU。 有些超级计算机相结合的NVIDIA GPU使用Intel或AMD的CPU。

英特尔提供一个超级大型芯片称为至强披7290以72芯作为主要的芯片,但它不整合的GPU。该至强融核凌动拥有CPU和向量处理器来进行复杂的计算。

一个新的大型芯片将是AMD的一个大胆的赌博。单个CPU和GPU芯片可以竞争力的价格,这将降低需要企业购买单独的芯片。

AMD成为服务器在2003年推出64位芯片后不久的双核芯片,但拖延和芯片基于推土机核心的最终注定了公司的服务器努力失败的主要参与者。

相信基于ARM的芯片将是服务器的未来,AMD还莫名其妙地被遗弃的的x86服务器芯片的发展。不过,ARM芯片还没有在服务器上捕获和Intel兑现AMD的失误。英特尔已垄断了90%以上的服务器芯片市场。

AMD的服务器计划已经回到了x86架构,而禅产生的兴奋。第一个基于禅宗的服务器将在明年来自多个厂商的上半年可用,素称。这些芯片在AMD和服务器制造商的双插槽系统正在测试,结果是令人鼓舞的,素称。

该公司将服务器芯片市场的选择,而不是追求各阶层,苏说。与英特尔不同,AMD并不丰富资源和最初专注于它认为将是最有利可图的市场。

AMD emerged as a serious threat to Intel in servers more than a decade ago, but after a series of missteps and bad chips, the company's server business is hanging on by a thread.

Now, AMD is rebooting its server chip business with the upcoming Zen CPU, which will also be used in PCs. AMD is getting creative with Zen and considering merging the CPU with a high-performance GPU to create a mega-chip for high-performance tasks.

"It's fair to say we do believe we can combine a high-performance CPU with the high-performance GPU," AMD CEO Lisa Su said during an earnings call on Thursday.

Su's comment was in response to a question on whether AMD would ultimately combine its Zen CPU with a GPU based on the upcoming Vega architecture into one big chip for enterprise servers and supercomputing.

"Obviously, it'll come in time," Su said. "It's an area where combining the two technologies makes a lot of sense."

It wouldn't be the first time AMD has built a mega-chip. It has already combined full-featured CPUs and GPUs on made-to-order chips for the Xbox One and PlayStation 4 gaming consoles. The 5-billion transistor Xbox One chip uses an eight-core AMD CPU code-named Jaguar and a Radeon graphics processor.

GPUs are being used as co-processors in some of the world's fastest computers for tasks like weather modeling, economic forecasting, and weapons design. They are also used by Google in data centers for deep learning tasks. Nvidia has cornered the supercomputing space while AMD has struggled with its FirePro high-performance GPUs.

But AMD's integrated mega-chip would be unique. Nvidia has high-performance GPUs but lacks a CPU. Intel's CPUs dominate servers, but it does not offer a GPU. Some supercomputers combine Nvidia GPUs with CPUs from Intel or AMD.

Intel offers a supercomputing mega-chip called Xeon Phi 7290 with 72 cores as a primary chip, but it does not integrate a GPU. The Xeon Phi has Atom CPUs and vector processors to carry out complex calculations.

A new mega-chip would be a bold gamble for AMD. A single CPU and GPU chip could be priced competitively, and it would reduce the need for companies to buy separate chips.

AMD became a major player in servers with the introduction of 64-bit chips in 2003 and dual-core chips shortly after, but delays and the failure of chips based on the Bulldozer core ultimately doomed the company's server efforts.

Believing ARM-based chips would be the future of servers, AMD also inexplicably abandoned the development of x86 server chips. But ARM chips haven't caught on in servers, and Intel cashed in on AMD's missteps. Intel has cornered more than 90 percent of the server chip market.

AMD's server plans have returned to the x86 architecture, and Zen is generating excitement. The first Zen-based servers will be available in the first half of next year from multiple vendors, Su said. The chips are being tested in dual-socket systems by AMD and server makers, and the results are encouraging, Su said.

The company will make server chips for select markets instead of pursuing all segments, Su said. Unlike Intel, AMD isn't rich on resources and is initially focusing on what it believes will be the most profitable markets.
