Intel's Six-Core Xeon 7400 "Dunnington" Processor Shipping on September 15th

According to CNET sources, Intel's six-core "Dunnington"processor will begin rolling out to servers on September 15th under the Xeon 7400 series. The new chip is Intel's first foray beyond four cores as well as their first to fuse multiple cores on a single die. It also features 16MB of L3 cache to help boost performance. The design is the last of the Penryn-class, and if the rumors hold true, we should see Core i7 (Nehalem) by the end of the year. [CNET via Electronista]

Intel's Six-Core Dunnington and Nehalem Microarchitecture Get Official

The pair of 45nm Intel chips that Sun oh-so-kindly leaked last month just got all official-like. Dunnington is "the first IA (Intel Architecture) processor with 6-cores, is based on the 45nm high-k process technology, and has large shared caches." Six cores, exciting! But not as exciting as Nehalem, which is Intel's "dynamically scalable" new processor microarchitecture which'll bring "dramatic performance and energy improvements" to Intel's chips. And that means what?

The platform will scale from two to eight cores, and eventually from "notebooks to servers." That's the scalable part, so you'll see it everywhere. Simultaneous Multi-Threading will let each core run two threads at once, plus it quadruples the memory-bandwidth of the current top-o'-the-line Xeons. It's also got an 8MB level-3 cache, Quickpath interconnects (up to 25.6GB per second), integrated memory controller (AMD what?) and supports up to DDR3-1333 memory, plus a bunch of other hardcore geek stuff, which you can scope out at Intel.

Intel's 6-Core Nehalem and Xeon Dunnington Processors Leaked

This is fascinating if you're planning on getting a new computer soon or if you're a gigantic spec nerd, but Sun just spilled the beans on Intel's upcoming processor lineup in the form of a leaked roadmap. In it, you can see that there's two six-core processors, one Xeon Dunnington and one Nehalem.

The Dunnington is for the server line, as a successor for the Xeon Tigerton, and will be "Intel's first Core 2 Duo processor with three dual-core banks." The Nehalem should be of more interest to most of our readers, as it's the Intel Penryn successor (consumer line), and will have on-die memory controllers for "the first time in 18 years," along with tri-channel DDR3 memory. This means it'll be quite a bit faster than what you're currently running in terms of memory bandwidth. [Daily Tech]

Intel Planning 6-Core "Dunnington" Microprocessor

According to the chaps at the Eclipse Developer's Journal (EDJ), Intel is planning a six-core microprocessor, which will go by the Dunnington moniker.

The six-core beast will be succeeded by the even meatier, Nehalem micro-architecture, which will support greater than eight cores. The work regarding the Dunnington project is still under wraps, but our friends at EDJ insist Intel has already put together a die, the size of a postage stamp, with three dual-core 45nm Penryn chips on it sharing a 16MB L3 cache. Allegedly, we'll see the Dunnington in either Q2 or Q3, this year—we'll be sure to keep you posted on any developments. [EDJ via The Inquirer]
