英特尔推出针对服务器和Thunderbolt的多款新芯片

英特尔(Intel)将在今年更新其服务器处理器产品线，增加三款基于 Atom 的新芯片。在日前于北京召开的 IDF 上，该公司透露其于服务器专用处理器产品的最新计划、新款 Atom SoC细节以及为服务器机架(包括其硅光子技术)定义参考设计的工作进度。 此外，英特尔并与Pericom公司讨论针对 Thunderbolt 的新款芯片细节。 Thunderbolt 是一种快速的外围接口，最初由英特尔所定义，并用于苹果 Mac 计算机中。 英特尔宣布推出两款基于 Atom 的SoC──代号为 Briarwood 的SoC针对储存系统；以及针对连网应用的 Rangely 。 Briarwood 又称为 Atom S12x9 ，这款目前已出货的32nm组件，可支持多达40个PCI Express Gen 2 信道、不透明桥接与硬件加速RAID。 英特尔只透露 Rangely 是一款22nm SoC，预计将在2013年下半年出货。此外，英特尔也在北京IDF上展示了 Avoton ，这是一款针对微型服务器开发的22nm Atom SoC。包括 Rangely 与 Avoton 都采用了新的 Atom 核心── Silvermont ，预计将可支持乱序执行。 至于采用Haswell架构的 Xeon 系列，包括了E3、E5与高阶 E7 Xeon 服务器芯片，英特尔宣布将在年中针对低阶单路服务器推出22nm E3 系列 Xeon 。该芯片功耗仅13W，较目前最低功耗 Xeon 所能实现的17W更低得多。

Haswell Xeon 将包括嵌入式绘图核心。英特尔并提供开发工具套件，以执行采用该处理器绘图核心的视频串流应用。 而在 E5 Xeon 市场，英特尔将在第三季出货双插槽系统用22nm Ivy Bridge EP 芯片。而在今年年底，还将为内建8个或更多处理器的系统推出 Ivy Bridge EX 处理器，预计将采用32nm制程。该系列芯片能在八插槽节点中处理高达 12TB DRAM。 此外，英特尔表示正为机架级服务器设计一款参考架构，预计将在2014年推出。该架构预计将搭载英特尔在去年宣布的硅光子互连技术。 去年，英特尔与中国阿里巴巴(Alibaba)、百度(Baidu)、腾讯(Tencent)与中国移动(China Mobile)共同发起针对客制机架设计的天蝎计划(Project Scorpio)。英特尔北京分公司也正开发可让中国客户利用的的云端运算系统。 本文授权编译自EE Times，版权所有，谢绝转载 本文下一页：Thunderbolt转向专业领域？

{pagination} Intel previews server and Thunderbolt chips Rick Merritt SAN JOSE, Calif. – Intel will refresh its line of server processors this year, adding three Atom-based chips to the mix. At its annual event in Beijing this week, the company will reveal a few details of the chips and its work defining a reference design for server racks that includes its silicon photonics. Separately, Intel and Pericom talked about new chips for Thunderbolt, a fast peripheral interface initially defined by Intel and used in Apple Macs. In Beijing, Intel announced two Atom-based SoCs -- Briarwood for storage systems and Rangely for networking. Briarwood, aka the Atom S12x9, is a 32-nm part that is shipping now and supports up to 40 PCI Express Gen 2 lanes, non-transparent bridging and hardware acceleration for RAID. Intel would only say Rangely is a 22-nm SoC that will ship in the second half of 2013. At the Beijing event, Intel showed a working demo of Avoton, it’s 22-nm Atom SoC for microservers. Both Rangely and Avoton use a new Atom core called Silvermont, expected to support out-of-order execution. As for its Xeon server chips, Intel announced it will ship in the middle of this year a 22-nm E3-class Xeon for low-end single-socket servers. The chip is part of its Haswell generation and consumes just 13 W, down from 17 W for its current lowest power Xeon today. Click on image to enlarge. Intel claims its 2013 Atom and Xeon chips will span the server waterfront. The Haswell Xeon will include embedded graphics. Intel will roll a developer’s kit for running video streaming applications using the graphics core on the processor. In its middle market E5-class, Intel will ship in the third quarter a 22-nm Ivy Bridge EP chip for dual-socket systems. By the end of the year, it will ship Ivy Bridge EX processors for systems with eight or more processors, presumably made in its 32-nm process. They will handle up to 12 terabytes of DRAM in an eight-socket node. Separately, Intel said it is working on a reference architecture for a rack-level server design that it will publish in 2014. The architecture will specify the silicon photonics interconnects Intel announced last year, at least as one design option. Last year, Intel worked with China’s Alibaba, Baidu, Ten Cent and China Mobile on Project Scorpio, a custom rack design. Intel’s Beijing office is also developing its own cloud computing system it will let China customers access. Thunderbolt edges toward pro markets Meanwhile, at the National Association of Broadcaster’s annual event in Las Vegas, Intel announced new Thunderbolt controllers and demonstrated a next-generation product still in development. The Intel DSL4510/4410 Thunderbolt controllers add DisplayPort 1.2 capability when connecting to native DisplayPort systems, improve power management and reduce cost. Intel also previewed prototype silicon of Falcon Ridge, a next-generation controller that runs at 20 Gbits/second, enabling 4K video file transfer and display simultaneously. Initial production is expected before the end of this year. Separately, Pericom Semiconductor announced six new products including a switch that handles Thunderbolt. The 10.3-Gbits/s Thunderbolt switch is designed to multiplex and de-multiplex Thunderbolt data paths into individual signals from the graphics processor and route them to a platform connector or end point. A Pericom spokesman said Thunderbolt is “being deployed more in the professional video storage and video editing systems.” The interface was initially seen as a possible mainstream PC interconnect and may still play a role in desktops and notebooks. “Given that we are moving to from 1080P to 2K/4K resolutions, having a 10.3G interface will ease the data movement between the PC and storage,” said the Pericom source.
