Your new graphics catch phrase: My sense is that the NV30 chip in the GeForce FX offers a little more complexity and flexibility than the F-buffer approach, but the real-world differences in performance and rendering output are likely to be minor. ATI says this cache has been optimized to work better with stencil buffer data, which should help when developers use stencil shadow volumes to create shadowing effects in future games like Doom III. About us Privacy policy Mailing list Mobile. However, as with traditional multi-pass approaches, pixel shader programs will have to be structured to account for the GPU’s per-pass rendering limitations. The pixel shaders on the R chip are limited to program lengths of 64 instructions, which simply isn’t enough to create some of the more compelling shader effects developers might want to use.

Finally, the R’s has an improved cache for Z-buffer reads and writes, to aid in the bandwidth-intensive task of handling pixel depth information.

The Radeon Pro, by contrast, topped out at F-buffer The most significant piece of new technology in the R, however, is more than a simple performance tweak. Essentially, to provide really complex shader effects in real time, you want to avoid making multiple rendering passes, at least in the traditional sense of full passes through the GPU pipeline. That is, info about a pixel’s position on the Z axis. The pixel shaders on the Radwon chip are limited to program lengths of 64 instructions, which simply isn’t enough to create some of the more compelling shader effects developers might want to use.

ATI has achieved more throughput than any other consumer graphics chip, and they’ve done so without resorting to a Dustbuster appendage.

ATI Radeon Pro (MB, AGP) Overview – CNET

Also, the company has tuned the chip’s memory controller to better arbitrate reads and writes during heavy use, which should especially help performance when rendering antialiased pixels. To understand why all of this multi-pass stuff matters and to get a sense why I get all hot and bothered when talking about DirectX 9-class hardware, go read my article about such things.

ATI has taken several measures to allow the R to put its memory bandwidth to good use. In this case, the chip must perform a color blend operation before writing the pixel to the framebuffer, which can cause problems with the look of the final, rendered output.

In order to produce more complex effects, the R would have to resort to multi-pass rendering. The R’s bit DDR memory interface runs at a higher clock speed, which allows the chip to have even more memory bandwidth than the Radeon Pro. The Radeon Pro will debut with an effective MHz memory clock speed, which gives it a very healthy Neutronbeam Zak, you know you can’t validate any of the above details without first throwing The concept is fundamentally simple, as many good innovations in computers are, but the impact of the change is profound.

Shader programs will largely be written in high-level shading languages like MS’s HLSL and broken down into passes by a runtime compiler. Dell returns to the stock market after six years.

For instance, multi-pass rendering 98000 handle transparent or translucent surfaces particularly well.

My sense is that the NV30 chip in the GeForce FX offers a little more complexity and flexibility than the F-buffer approach, but the real-world differences in performance and rendering output are likely to be minor. Mark and Kekoa Proudfoot at Stanford University. With fast bit DDR memory, improved pixel shaders, and more efficient use of memory bandwidth, the Radeon Pro looks to be the new king of the hill. ATI says this cache has been optimized to work better with stencil buffer data, which should help when developers use stencil shadow volumes to create shadowing effects in future games like Doom III.

Merry Christmas from The Tech Report staff! NVIDIA’s GeForce FX Ultra may have captured at 128mn part of the technology and performance titles for itself, but the cards are so rare, we haven’t even been able to secure one for review.

Voldenuit It’s nice of Raddon to fill in for Chuckula over the holidays. In all, the F-buffer is a crucial enhancement to the R that reasserts ATI’s technology leadership in graphics. However, as with traditional multi-pass approaches, pixel shader programs will have to be structured to account for the GPU’s per-pass rendering limitations.
