SAN FRANCISCO: CHIPMAKER Intel has revealed more details about its server processor roadmap, including its upcoming Atom chips codenamed Avoton and Rangeley and new 14nm Xeon and Atom parts codenamed Broadwell and Denverton, respectively.

At a datacentre event in San Francisco Intel announced that the upcoming Atom chips codenamed Avoton and Rangeley will be known as the Atom C2000 series. Avoton targets microservers and is the successor to the Atom S1200 line codenamed Centerton, while Rangeley is aimed at network and communications kit.

Still scheduled to ship sometime later this year, the Atom C2000 chips are fabbed on Intel's 22nm process technology, while the Atom S1200 chips are 32nm parts. This enables them to deliver up to four times the performance per watt, according to Intel.

The Atom C2000 series is a 64-bit system on chip (SoC) design with up to eight cores, which now offer out of order execution, unlike earlier Atom chips.

Jason Waxman, general manager of Intel's Cloud Infrastructure group said that Avoton will offer a significant increase in performance per watt over the existing Atom S1200 parts, which are featured in HP's Moonshot microserver products.

"Centerton is a good product, but it's nothing compared to what Intel is bringing to the market with Avoton," he said.

As well as up to eight cores, it supports Intel's virtualisation technologies and up to 64GB of DDR3 memory. As they are SoCs, Atom C2000 chips also integrate on-chip I/O, including four Gigabit Ethernet ports, SATA controller circuitry and 16 PCI Express lanes.

Intel also disclosed that it will deliver its first 14nm server SoCs next year, codenamed Broadwell and Denverton.

Intel low-power server roadmap

Broadwell will be Intel's first Xeon SoC, and will integrate not only I/O but an on-chip fabric interconnect, and will target server, storage and network applications.

"Some customers have been telling us they still want the performance of Xeon, but the extra features in the SoC products, so this will be the first Xeon-based SoC," said Waxman.

Meanwhile, Denverton will follow Avoton in the microserver market, with "more cores, more of everything," he said.

He reiterated Intel's belief that its architecture is the best choice for servers, because of the overwhelming mass of operating system and application support for x86 systems.

However, Waxman now claims that with Avoton, Intel will be able to beat the rival ARM architecture even on power efficiency.

"We believe that on a per-core basis, we will have the lowest power [use] in the industry," he said. µ
