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

Nvidia will take part in the launch of Via's Isaiah processor slated for next week, just prior to Computex in Taipei, Taiwan.

Via will provide the central processing unit and motherboard, plus the core logic (chipset) solution, while Nvidia will provide the graphics processing unit, said Drew Henry, general manager of Nvidia's platform products division.

Nvidia will offer standalone "discrete" graphics for both notebook and desktop platforms using the Isaiah chip, Henry said.

"We are participating in the launch. We wish to work with them in demonstrating any number of different visual computing applications," … Read more

Nvidia confirmed Friday that it has acquired RayScale, a small company that develops ray-tracing technology. Financial terms of the deal have not been disclosed.

Ray tracing 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.

PC graphics technology today uses rasterization. (A discussion of ray tracing vs. rasterization.)

AMD announced today that its next-generation ATI Radeon graphics cards will be the first commercial implementation of GDDR5 memory. According to the company, the new memory will allow for faster, smaller, and cheaper graphics cards:

"The higher data rates supported by GDDR5--up to 5x that of GDDR3 and 4x that of GDDR4--enable more bandwidth over a narrower memory interface, which can translate into superior performance delivered from smaller, more cost-effective chips."

The benefits of GDDR5 memory also include increased accuracy in calculations by way of new error detection mechanisms and more power-efficient graphics cards, according to AMD.

Jen-Hsun Huang doesn't pull any punches. And Intel is a favorite punching bag these days.

I had a chance to sit down with the Nvidia CEO as he described his company's philosophy and what sounds like the first volleys of a long battle with Intel.

A quick backdrop: Nvidia is the largest graphics chip company in the world, with quarterly revenue in the $1 billion range. Although Intel and Nvidia seem to exist in symbiotic bliss inside many PCs, this doesn't reflect the two companies' business models, which are in many respects far apart.

Intel is a … Read more

Nvidia's hostility toward Intel is on a high boil these days. In its latest dig against the central processing unit (CPU) and the company that makes the lion's share of CPUs, an Nvidia VP said in a private missive that the CPU is dead and it has "run out of steam."

But wait. That's not what Nvidia really thinks. The message cited by the The Inquirer is "not a public statement," said Brian Burke, an Nvidia spokesperson. "The views in (Roy Tayler's) e-mail do not mirror the views of Nvidia." (… Read more

We already know that Nvidia doesn't think highly of Intel's graphics technology. But is it really that bad, or is it good enough for most PC users?

Let's focus on the graphics technology that Intel has been supplying in volume to notebook PC makers over the last year or so. Namely, the Graphics Media Accelerator (GMA) X3100, which is integrated into the GM965 chipset. Like many graphics platforms (Nvidia and ATI not excluded) it has a checkered past: late drivers (very late in some cases), broken DirectX promises, and erratic performance.

That said, tens of millions of … Read more

Even the mightiest graphics boards bow to Crysis. And Nvidia's newest dual-graphics board is no exception.

First some background. Crysis is a science fiction computer game developed by Germany-based Crytek and published by Electronic Arts. "Crysis is visually stunning, packed with intelligent, thrilling gameplay, and easily one of the greatest shooters ever made," according to GameSpot (which is owned by CNET Networks). For hardware reviewers, it's the ultimate gaming test of a graphics card.

Though so far the reviews of Nvidia's GeForce 9800 GX2 are positive ("The GeForce 9800 GX2 is an absolute powerhouse, … Read more

The graphics processing unit (GPU) is in, the central processing unit (CPU) is out. That was one of the main themes running through the Nvidia fourth-quarter conference call earlier this week. Nvidia is the largest graphics chip supplier.

During the call on Wednesday, Jen-Hsun Huang, President and CEO of Nvidia, repeated one thing often: GPUs are playing more of a central role in PCs, CPUs less so. "The CPU has become fast enough for the vast majority of (PC) users," he said. "PC enthusiasts, gamers, and design professionals have know this for some time." The GPU … Read more
