英特爾(Intel)將在今年更新其服務器處理器產品線，增加三款基于 Atom 的新芯片。在日前于北京召開的 IDF 上，該公司透露其于服務器專用處理器產品的最新計劃、新款 Atom SoC細節(jié)以及為服務器機架(包括其硅光子技術)定義參考設計的工作進度。 此外，英特爾并與Pericom公司討論針對 Thunderbolt 的新款芯片細節(jié)。 Thunderbolt 是一種快速的外圍接口，最初由英特爾所定義，并用于蘋果 Mac 計算機中。 英特爾宣布推出兩款基于 Atom 的SoC──代號為 Briarwood 的SoC針對儲存系統(tǒng)；以及針對連網(wǎng)應用的 Rangely 。 Briarwood 又稱為 Atom S12x9 ，這款目前已出貨的32nm組件，可支持多達40個PCI Express Gen 2 信道、不透明橋接與硬件加速RAID。 英特爾只透露 Rangely 是一款22nm SoC，預計將在2013年下半年出貨。此外，英特爾也在北京IDF上展示了 Avoton ，這是一款針對微型服務器開發(fā)的22nm Atom SoC。包括 Rangely 與 Avoton 都采用了新的 Atom 核心── Silvermont ，預計將可支持亂序執(zhí)行。 至于采用Haswell架構的 Xeon 系列，包括了E3、E5與高階 E7 Xeon 服務器芯片，英特爾宣布將在年中針對低階單路服務器推出22nm E3 系列 Xeon 。該芯片功耗僅13W，較目前最低功耗 Xeon 所能實現(xiàn)的17W更低得多。

{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.
