Probably a case door window on the left side Almost romantic. As you have guessed by now we are reviewing Hercules latest and greatest, the 3D Prophet Pro.

It amazes me how ATI managed to advance itself way up there in that extremely competitive market. Two maybe three years ago they had a reputation of building so-so graphics cards with mostly buggy drivers and now look again, a lot has changed since then. They certainly had an answer to that.

The product, as stated my friends, is the all new Radeon Pro. A highly efficient and programmable graphics card with a computational speed that is simply breathtaking.

Instead of moving towards a 0,13 Micron fabrication process, like the new and are, ATI decided it would be saver to go with the older 0. F-buffer The most significant piece of new technology in the R, however, is more than a simple performance tweak. 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 128mb ddr ati radeon 9800 pro use. In order to produce more complex effects, the R would have to resort to multi-pass rendering.

Multi-pass rendering is nifty because it overcomes a lot of technical limitations, but it's a performance killer because it duplicates lots of work unnecessarily. 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. To understand why all of this multi-pass stuff matters and 128mb ddr ati radeon 9800 pro 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 addressed the R's pixel shader limitations in R by implementing something called an F-buffer.

The genesis of the F-buffer idea was a paper by William R. Mark and Kekoa Proudfoot at Stanford University.

Mark and Proudfoot suggested the F-buffer as a means of storing intermediate results of rendering passes without writing each pixel to the frame buffer and taking another trip through the graphics pipeline. ATI Storing intermediate results in a FIFO buffer not only offers the potential for big performance increases over traditional multi-pass techniques, it also sidesteps a number of problems.


For instance, multi-pass rendering doesn't handle transparent or translucent surfaces particularly well. 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. The F-buffer approach does have some 128mb ddr ati radeon 9800 pro, but they aren't show-stoppers, from what I gather.

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.


Shader programs will largely be written in high-level shading languages like MS's HLSL and broken down into passes by a runtime compiler. With high-level shading languages, developers need not think much about the hardware's per-pass limitations.

Honestly, I didn't expect ATI to address the R's 128mb ddr ati radeon 9800 pro pixel shader limit with this "half-generation" refresh chip, but they've apparently done so. 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. In all, the F-buffer is a crucial enhancement to the R that reasserts ATI's technology leadership in graphics.
