Investigating Intel's Lynnfield mysteries

I have a few questions to ask at this week's Intel Developer Forum....

Why is Intel using a more expensive chip for the new Core i5 and cheaper Core i7 processors? Why does this new chip--code-named Lynnfield--appear to have features Intel isn't using? What's the connection between Lynnfield and a future Intel chip code-named Jasper Forest?

These questions arose as I've been getting ready for IDF by reviewing recent press releases and news stories about Intel's current and forthcoming products, and chatting with fellow analysts about what we're looking forward to seeing there.

The recent announcements of the Core i5 and new Core i7 processors seemed pretty straightforward. Consider Brooke Crothers' piece on CNET: "Out with the old: Intel makes Core 'i' chips cheap." As Crothers explains, the facts are simple: the new Core i7 800-series slots in under the existing 900-series and replaces some older parts. The Core i5 is a new line, clearly positioned below the Core i7. Features, performance, and prices are all lower. That's as it should be.

But in looking at the coverage on some enthusiast sites, a fact jumped out at me. The Lynnfield chip is 12.5 percent larger than the Bloomfield chip used in the higher-priced Core i7 900-series processors (296 square mm vs. 263 square mm), in spite of the fact that Lynnfield only has two memory interfaces and no QuickPath Interconnect (QPI) link.

The big difference between the chips is the addition of 16 lanes of PCI Express on Lynnfield, but that's only about 80 pins plus the control logic. The changes should have roughly canceled each other out. Maybe one chip would be a little bigger than the other, but not by this much.… Read more

Nvidia about-face brings questions

Update at 6:45 .p.m. with additional information about QPI licensing.

Nvidia's last-minute conference announcement has turned into a bit of shocker.

Despite all the chest thumping at its gaming conference this week, the high drama of Nvision reached its denouement with a waving of the white flag. The world's largest graphics chip supplier announced support for high-end gaming graphics using Intel silicon. This has raised doubts about its clout in the gaming PC industry, based on the reaction at many hardware enthusiast Web sites and at least one PC maker.

Representative of the shock expressed after … Read more

Nvidia boosts graphics on Intel i7, preps integrated chip

Update on August 28 at 3:30 p.m. with comments on SLI and AMD-ATI

Nvidia is extending its support for Intel's upcoming Core i7 processors while it prepares to announce next-generation integrated graphics silicon.

The announcement marks an effort to expand Nvidia offerings on Intel's next high-end desktop platform, which had previously been referred to as "Bloomfield." Intel branded it Core i7 prior to the company's developer forum last week. Nvidia has already said that it has no intention to build a chipset for Intel's next-generation interconnect technology called QuickPath Interconnect or QPI, … Read more

Nehalem: Intel's near future gets real

Intel has scores of futuristic, potentially game-changing research projects but Nehalem is bet-the-farm reality. The first Nehalem chips--and the first drops of what should become a giant revenue stream--will arrive later this year. So, it is not surprising that real silicon and real systems are starting to appear.

What is Nehalem exactly? The architecture will scale from two to eight processor cores, have faster chip-to-chip communication (Intel calls this technology QuickPath), do a better job of adjusting performance levels to suit power needs, and have a higher level of integration (more logic will be built directly onto the processor die). … Read more

Nvidia targets graphics technology at Intel Nehalem

Update at July 15, 3:00 a.m. PDT with additional information and corrections concerning the Intel-Nvidia dispute.

Nvidia said Monday that its multichip technology will be architected to work on Intel's upcoming Nehalem chip platform.

This announcement may help Nvidia to work around a standoff with Intel over whether Nvidia can make chipsets that work with Intel's next-generation Nehalem platform, due later this year. And also demonstrates that despite Nvidia CEO Jen-Hsun Huang' s rhetoric, Nvidia must cooperate with Intel in order to thrive.

Monday's announcement has no relation to separate licensing negotiations, according to sources … Read more

At IDF Shanghai, Intel's vision of chips

While the marquee processor theme at IDF Shanghai is "milliwatts to petaflops," Intel is also set to offer a vision of universal connectivity.

The main theme for the event, which starts Wednesday, Beijing time, refers to "very, very big to very, very small and low power," according to Pat Gelsinger, senior vice president and co-general manager of Intel's digital enterprise group, speaking in a video.

(See: Intel rolls out five new Atom processors.)

"Milliwatts" refers to chips such as Atom, a tiny low-power, low-cost processor destined for ultramobile devices and low-cost desktops typically … Read more

IDF Shanghai preview: from Atom to Bloomfield to SSD

The following is a partial list of the sessions at this week's Intel Developer Forum in China, which runs April 2 to 3. Topics set to be covered at IDF Shanghai include Netbook, Nettop, Bloomfield (Nehalem), solid-state drives, QuickAssist (accelerators), system-on-chip (Tolapai), and USB 3.0.

The items below are taken directly from Intel's own material:

Intel Atom Processor for the Desktop The Essential Building Block for Purpose Built, Basic Desktop Computing Devices: Intel's strategy for basic desktop computing devices. See how the new Intel Atom processor based desktop platforms provide the world's best solution for … Read more
