Update at 9:00 a.m. PDT July 9 adding new information that links Larrabee cores to Pentium technology

The "rumor" is true: Intel's future Larrabee graphics chip does use processing cores based on the company's venerable Pentium chip.

Larrabee, due in 2009-2010, is a high-end graphics chip with many processing cores targeting market segments that Nvidia and AMD-ATI now dominate.

Here's the starting point for the Larrabee-is-a-Pentium theme. The Web site Custom PC cited an article from German-language Heise, in which Custom PC says--via a link to a Babel Fish translation of the Heise … Read more

Intel has upstaged Advanced Micro Devices at DreamWorks Animation. The movie studio has decided to drop AMD and go with processors from Intel, citing better performance and a more promising roadmap.

DreamWorks specifically mentioned Intel's upcoming Nehalem processor and Larrabee graphics chip as reasons for the switch.

Intel and DreamWorks announced Tuesday that they had formed a strategic alliance for 3D filmmaking technology. DreamWorks plans to produce all its feature films in stereoscopic 3D--which requires the viewer to wear special glasses for enhanced 3D--beginning next year. Intel will provide DreamWorks with "the latest high-performance processing technologies, including future … Read more

The Apple MacBook Air has been a ground-breaking first-generation product (in my opinion). So, what will Apple do to top it when an update comes later this year? There are some telling indicators already. This is what I expect--and hope for--as a user.

First, a disclaimer. I am not an Apple fanatic. The MacBook Air is the first Apple product I have ever used for more than a few days. For well over a decade, I have been wedded to Wintel (Windows-Intel) laptops.

Before I dive into upcoming features, I should also mention that I have been extremely pleased with … Read more

Germany-based Cizmo is offering an Intel Centrino 2-based gaming laptop that shows what's in store for mobile gamers this summer.

Intel's newest crop of Centrino 2 Montevina mobile processors are slated for a July 14 rollout and will include the Extreme X9100 processor: the first Penryn-class mobile processor to break the 3.0GHz barrier.

The Cizmo 17-inch CX1730M can be configured with an Intel X9100 Extreme processor running at 3.06GHz. A key feature of Intel X-class mobile processors is that they are designed to be overclocked.

The CX1730M can also take an Nvidia GeForce 8800M GTX graphics chip.

Memory based on the new DDR3 standard is also offered. DDR3 SDRAM can be hooked up to Intel's faster 1066MHz front-side bus. Currently, Intel's front-side bus--which carries data between the processor and other silicon--runs at 800MHz.

Other specifications for the CX1730M include Intel's newest PM45 chipset. Intel stated last month that initially only the PM chipset--for discrete (standalone) graphics chips--would be available. The GM version with Intel integrated graphics will arrive in August. … Read more

Nvidia has posted a video that involves the new GTX 280 chip, overclocking, lots of liquid nitrogen, and the Nvidia labs. Oh, and no quad-core processor. Get the point?

"A lot of people believe you need an Intel quad-core or Intel quad-core Extreme to build an extreme PC," says the post by "Steffee" on the Nvidia Web site. "Today I'm going to build a gaming PC using the Intel Core 2 Duo. That's duo. Got that? Duo, two cores."

I think the point the blogger is trying to make is that the … Read more

Nvidia has announced it will release a graphics chip that matches Advanced Micro Device's manufacturing process--an advantage that the latter has often touted.

The Nvidia GeForce 9800 GTX+, announced Thursday, is made on a 55-nanometer process. Current Nvidia processors--including the just-released GTX 200 series--are made on a slightly "fatter" 65nm process. AMD has moved most of its graphics chips to a 55nm process.

Typically, the smaller the process, the more energy-efficient a processor is. Smaller processes also typically offer better performance. Tech Web site PC Perspective has photos showing that the chip package is smaller than a … Read more

Brighter, crisper images are the goal for top Intel researchers in their work on future graphics technology.

I talked Wednesday with Intel's Jerry Bautista, the co-director of the Tera-scale computing research program, and Daniel Pohl, an Intel researcher. I focused mostly on a concept called ray tracing but also questioned them about Intel's upcoming Larrabee processor.

First, some background. Ray tracing--whether you agree or disagree about its viability--has been a fairly hot topic. It has been mentioned frequently by Intel over the last six months. An Intel blog titled "Real Time Ray-Tracing: The End of Rasterization?" and later comments by Intel executives that the company is looking at doing ray tracing on its processors set the stage for debate on the viability of ray tracing in mainstream gaming.

Ray tracing is a technique for rendering three-dimensional graphics using complex light interactions, allowing the creation of extremely detailed reflective surfaces, for example, with stunning photorealistic results.

In the future, ray tracing may compete with today's traditional raster-based graphics used in games running on Nvidia and AMD-ATI graphics processors. Intel claims ray tracing runs better on general-purpose processors, such as its Core 2 Quad processors, than on traditional graphics processors. Ray tracing may also run on future processors such as Larrabee.

Intel CEO Paul Otellini alluded to this at a Sanford C. Bernstein & Co. Strategic Decisions Conference last month. Asked who Intel's major future competitors are, Otellini responded, "In graphics, as we move up the food chain, we're bouncing into ATI via AMD and Nvidia more than we used to. And I don't expect that to abate anytime soon." … Read more

UPDATE: On Monday, Advanced Micro Devices and Nvidia are launching graphics chips based on distinctly different design philosophies.

Nvidia's GTX 280 and GTX 260 are designed to deliver the biggest performance bang per chip. A so-called "monolithic" approach packs 1.4 billion transistors and 240 processing cores onto one piece of silicon.

(See Peter Glaskowsky's review of the GTX 280.)

AMD's modular approach tends toward less is more: smaller, less power-hungry chips that can be strung together to achieve higher performance. The company plans to implement this strategy with the HD 4850 and HD 4870 … Read more

Via Technologies is set to go mainstream. On Thursday, Via launched the low-power Nano processor line that will compete with Intel's Atom processor and likely give the chip supplier some mainstream PC street cred.

Formerly referred to by the code name Isaiah, Nano is based on the x86 architecture, meaning it can run the same software as chips from Intel and Advanced Micro Devices.

With Nano, Via is angling for more mainstream notebook and mini-notebook designs such as Hewlett-Packard's 2133 Mini-Note PC, which uses Via's current C7 processor. Low-cost desktops will also be a target market, as … Read more
