New Atoms announced, amidst leaks about 2011 successors

Aug 16, 2010 — by LinuxDevices Staff — from the LinuxDevices Archive — 2 views

Intel says it is now shipping two new 1.8GHz Atoms, the single-core D425 and dual-core D525, aimed at networked storage appliances. Meanwhile, leaks have provided information about “Medfield” — a 2011 successor to the Atom-based “Moorestown” SoC — and forthcoming “Sandy Bridge” desktop CPUs.

The CPUs shipping today are the latest in Intel's Pine Trail series of Atoms (also known as "Pine View" when their companion I/O controllers are taken into account). The single-core D425 and dual-core D525 were actually announced in June at the Computex show in Taiwan, but the chipmaker has provided a (slight) surprise by releasing the parts with a 1.8GHz clock speed instead of the 1.66GHz clock that was originally mooted.

According to Intel, the D425 and D525 include on-board GMA3150 graphics (as do the other Pine Trail CPUs) and support either DDR3 memory at 800MHz, or 800/667MHz DDR2 memory. As shown in the table below, TDPs are identical to the CPU's DDR2-only predecessors.

Clock speed Cores Second-level cache Memory TDP
N450 1.66GHz 1 512KB 667MHz DDR2 5.5 Watts
N455 1.66GHz 1 512KB 800MHz DDR3 5.5 Watts
N470 1.83GHz 1 512KB 667MHz DDR2 6.5 Watts
N475 1.88GHz 1 512KB 800MHz DDR3 6.5 Watts
D410 1.66GHz 1 512KB 667/800MHz DDR2

D425 1.8GHz 1 512KB 800MHz DDR3 or 667/800MHz DDR2 10 Watts
D510 1.66GHz 2 1MB 667/800MHz DDR2 13 Watts
D525 1.8GHz 2 1MB 800MHz DDR3 or 667/800MHz DD2 10 Watts

Intel's "Pine Trail" Atoms

There seems to be no reason the new D425 and D525 wouldn't appear in low-cost desktop computers as well as some embedded devices. However, Intel says the new processors are "optimized for networked storage devices," and suggests pairing the CPUs with the 802801HR I/O controller, an embedded-focused part that supports RAID and has a maximum TDP of 4.3 Watts.

Intel announced a NAS reference platform in March based on the 82801HR and Pine Trail processors, the first manifestation of which was the LG N482 pictured below. Since that time, Acer, Cisco, LaCie, Netgear, Super Micro, Synology, and Thecus have all announced similar products, the chipmaker says.

"Medfield" details leak

Details of a smaller, more power-thrifty Atom codenamed "Medfield" have emerged, thanks to what appears to have been a presentation by Intel engineer Vadim Sukhomlinov. Pictured at right, Sukhomnilov is said by his LinkedIn Profile to be working to achieve a successful launch of the chipmaker's "Moorestown" platform in Russia.

The presentation was reportedly discovered last week on Intel's website by IDG's Agam Shah, among others. It has since been removed, but at the time of writing may be found in Google's cache, here.

According to the document, "Medfield" will be a 2011 successor to "Moorestown," also known as the Z6xx. The Z6xx was announced in June, along with a version known as Oak Trail, whose "Whitney Point" additions — SATA, HD Audio, HDMI, and a variety of legacy I/O — will make it capable of running Windows 7, among other operating systems such as Linux.

Intel has said "Moorestown" will cut idle power consumption to 1/50th of the first Atom, the Z5xx ("Menlow"), permitting devices based on it to deliver up to ten days of standby. (For further details, see our earlier coverage, here.)

We haven't seen Intel give a firm date for Z6xx or Oak Trail shipments, but it's likely the chips will ship during the early part of 2011 (we'd expect to see announcements of devices based on them at January's Consumer Electronics Show). Meanwhile, according to the Sukhomlinov presentation, Medfield is already queued up for release later in the year.

It's said that by switching from Moorestown's 45nm process to 32nm, as well as by integrating added functionality, Medfield will take up half the board space — making it more suitable for smartphones and other compact devices. Featuring a further (unspecified) reduction in power, Medfield will reportedly also have twice the graphics performance of Moorestown, which was already claimed to double that of Menlow.

New "Sandy Bridge" processors

Details of Intel's forthcoming "Sandy Bridge" desktop processors have also leaked onto the Internet, where they've been widely quoted (and misquoted) by tech websites.

Intel first tipped the Sandy Bridge CPUs in July, promising that it would provide further information at its Intel Developer Forum (IDF) next month in San Francisco. Due in early 2011, the revised Core processors will offer greater performance, better power conservation, and enhanced graphics capabilities, according to the chipmaker.

Last week, a list of Sandy Bridge CPUs appeared on several websites, most of which attributed it to a site called MacBidoullie. As far as we can determine, the information actually originated from the German website ComputerBase, which later updated its list thanks to information from a Taiwanese site known as EXPReview.

Whatever its actual provenance, the list (below) appears to be credible, and shows Intel adding a digit to the names of its 2011 Core processors — along with marginally higher clock speeds. As with the 2010 crop of Cores, TDPs range from 35 to 95 Watts. Graphics performance should be significantly better, however, since the integrated GPUs (graphics processing units) now benefit from the same TurboBoost mode as the CPUs.
