Intel's fourth-quarter warning is not only bad news but bad timing. With the Consumer Electronics Show kicking off Thursday adorned by all those bright, shiny gadgets, Intel effectively said: gadgets maybe, but not so bright and shiny.

And for an Intel warning, this one was particularly dire. The biggest chip bellwether said it now expects only $8.2 billion in revenue for the quarter, a 23 percent drop from the year-earlier period, and 20 percent from the third quarter. And this comes after issuing a warning on November 12.

So what's happening? The clearest example of the gloom … Read more

More dire forecasts for the chip industry.

On the heels of comments from a chip industry watchdog group last week saying the chip equipment business is "on hold," Taiwan Semiconductor Manufacturing Company (TSMC), the world's largest contract chip manufacturer, said PC-related chip shipments are expected to be off 20 percent in the fourth quarter.

This bodes ill for PC makers, which appear to be cutting way back on chip orders.

"(For) our fourth quarter computer-related wafer shipments...we expect to see over a 20 percent decline. Which is very severe...compared to a seasonal mid-teens percentage … Read more

Intel announced on Monday that it will be presenting a paper at Siggraph 2008 about its "many-core" Larrabee architecture, which will be the basis of future Intel graphics processors.

The paper itself, however, has already been published, and I was able to get a copy of it. (Unfortunately, as you'll see at that link, the paper is normally available only to members of the Association for Computing Machinery.)

The paper is a pretty thorough summary of Intel's motives for developing Larrabee and the major features of the new architecture. Basically, Larrabee is about using many simple x86 cores--more than you'd see in the central processor (CPU) of the system--to implement a graphics processor (GPU). This concept has received a lot of attention since Intel first started talking about it last year.

Graphics performance improves rapidly. We can be confident that each new generation of graphics chips will be faster than the previous one, and that AMD and NVIDIA will regularly surpass each other with new product launches. I've been watching this process professionally since 1996, when I began covering graphics technology for Microprocessor Report.

As of today, NVIDIA is on top. The new GeForce GTX 280 is the fastest graphics chip you can get. See the first part of this review for details of the chip itself.

If you can get one, anyway. NVIDIA says boards based on the GeForce GTX 280 and its companion GeForce GTX 260 will be available "in quantity" tomorrow (June 17), but if previous launches are any indication, those quantities won't be enough to satisfy everyone.

And you may not be able to afford one-- a GTX 280 board with 1GB of RAM will likely be priced around $649, while GTX 260 boards with 896MB will go for about $399. (The GTX 280 / 1GB board I tested was made by NVIDIA, so it isn't necessarily representative of commercial products.)

But avid gamers won't be discouraged by these prices. Both AMD and NVIDIA like to point out that an expensive graphics card is a much better investment than a high-end CPU or motherboard if you care about gaming.

The standard of comparison for gaming performance is the number of frames per second that can be rendered for a given combination of screen resolution and quality features... or, conversely, what resolution and features can be used without reducing the frame rate below a playable level.

So in my own testing, I used frame rate as a metric for games that could run acceptably with maximum quality at the maximum resolution of my monitor (1,600 x 1,200 pixels), and quality for other games.

I did my testing with four games:… Read more

Today, NVIDIA officially announces its new GeForce GTX 200 family of graphics processing units (GPUs) and the first two products in the family, the GeForce GTX 280 and the GeForce GTX 260.

The GeForce GTX 280 is the new flagship of NVIDIA's GPU product line, taking over from last year's GeForce 9800 GTX. (The change in the product-name format from "9800 GTX" to "GTX 280" is potentially confusing and doesn't seem that useful to me, but I'm sure we'll get used to it over time. I suppose NVIDIA's other choice was to go with numbers above 10,000, which might have been even worse.)

NVIDIA disclosed the details of these products at an Editor's Day conference in May, and most of the attendees, including myself, received GTX 280 graphics cards for editorial review. These cards are NVIDIA reference boards, not retail products.

I'll be doing this review in multiple parts, each addressing a different aspect of these products and the effects they'll have on the PC graphics market.

First, an overview of the GTX 280 chip itself.

This is a huge chip. NVIDIA won't say exactly how large, and I'm not going to bust open the chip package on my reference board just to find out, but NVIDIA VP of technical marketing Tony Tamasi says… Read more

Taiwan Semiconductor Manufacturing, the largest contract chip manufacturer in the world, will crank up its MEMS foundry business. Micro-Electro Mechanical Systems (MEMS) technology is used in Apple's iPhone and the Nintendo Wii.

MEMS typically have a microprocessor and other components such as microsensors. For example, MEMS technology is used in the iPhone and Wii to allow these devices to detect motion and changes in orientation.

In the iPhone, a device called an accelerometer detects when the user rotates the iPhone from portrait to landscape modes, then automatically adjusts the display, so the entire width of a web page or … Read more

Taiwan Semiconductor Manufacturing Corp., the world' largest chip foundry, will start making microprocessors for Sun Microsystems, a big change for both companies.

Sun has employed Texas Instruments for years to make its chips. TI, however, is ramping down a its foundry work. TI makes most of its money by producing chips for the cell phone market, where cost is often more important than cutting edge manufacturing technology. As a result, TI has signaled it won't race ahead with companies like Intel and Advanced Micro Devices to be the first (or one of the first) to graduate to an advanced … Read more

While AMD isn't giving away any information on its future fab plans, a major chip foundry is gearing up for a big new customer.

TSMC, the largest chip foundry in the world, is apparently planning to take on a new customer that wants to use the high-k dielectrics and metal gates introduced earlier this year by both Intel and IBM. Sumner Lemon of IDG News Service sat through a TSMC earnings call in which company executives mentioned a mysterious new customer would be coming on board in the second half of 2008.

There are not a lot of folks … Read more
