It’s nice of Krogoth to fill in for Chuckula over the holidays. 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 limitations, but they aren’t show-stoppers, from what I gather. In all, the F-buffer is a crucial enhancement to the R that reasserts ATI’s technology leadership in graphics. Merry Christmas from The Tech Report staff! 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.

That is, info about a atii position on the Z axis. 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. ATI has addressed the R’s pixel shader limitations in R by implementing something called an F-buffer. Merry Christmas from The Tech Report staff! Finally, the R’s has rareon improved cache for Z-buffer reads and writes, to aid in the bandwidth-intensive task of handling pixel depth information.

Read on as we examine the Pro in detail, exploring the performance and technology behind ATI’s latest and greatest. NVIDIA’s GeForce FX Ultra may have captured at least 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.

If you want to understand the technology from which the R is derived, please read our review. Mark and Kekoa Proudfoot at Stanford University.

The key things you need to know about the R chip are fairly basic. About us Privacy policy Mailing list Mobile. Steam names the best-selling games of Neutronbeam Zak, you know you can’t validate any of the above details without first ddr Dell returns to the stock market after six years.

The genesis of the F-buffer idea was a paper by William R. Honestly, I didn’t expect ATI to address the R’s instruction pixel shader limit with this “half-generation” refresh pto, but they’ve apparently done so. ATI has achieved more throughput than any other consumer graphics chip, and they’ve done so without resorting to a Dustbuster appendage.

The Radeon Pro will debut with an effective MHz memory clock speed, which gives it po very healthy In order to produce more complex effects, the R would have to resort to multi-pass rendering. Shader programs will largely be written in high-level shading languages like MS’s HLSL and broken radeeon into passes by a runtime compiler.

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.

With high-level shading languages, developers need not think much about the hardware’s per-pass limitations. Hard to argue with that. We’ve already reviewed the Radeon Pro in some depthand I will try to avoid repeating myself here. Voldenuit It’s nice of Krogoth to fill in for Chuckula over the holidays. Your new graphics catch phrase: ATI has taken several measures to allow the R to put its memory bandwidth to good use. F-buffer The most significant piece of new technology in the R, however, is more than a simple performance tweak.

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. 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.

No, that’s not a huge gain in terms of bandwidth overall, but it’s not bad. 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.

It’s nice of Krogoth to fill in for Chuckula over the holidays. 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. The F-buffer approach does have some limitations, but they aren’t show-stoppers, from what I gather.
