Helpp...hardware knowledge required...please

beckham_m7u · January 13th, 2003

Guys, I desperately need help here…I just remember that the day after tomorrow (Wednesday), I have to give a presentation about hardware. And I choose ATI Radeon 9700 PRO, I’ve done the paper typing but I’m a little bit (read: much much) confused now. It’s about features that Radeon provide:

1. Vertex Shader
What’s the use of this feature? As I know, it’s for counting geometries needed to render a graphic. But is that all? I read ATI said that 4 vertex parallel shader can process one vertex per clock. What does that mean?
2. Vertex and Pixel Shader
What’s the differences between Vertex Shader and Pixel Shader?
3. What’s the use of Pixel Rendering Pipeline?
4. What’s anisotropic filtering?
This is the most confusing feature, I think. What’s with the angle of viewer and things? Don’t get it?? And if I can get some clear pictures of the differences between Radeon’s AF and Geforce’s AF that’ll be great, since I’ve downloaded some pictures from the net and none of them showed a clear difference
5. How’s the work way of N-patch? / Truform?
6. What’s the plus minus using Radeon 9700 Pro compared with Geforce 4 Ti 4600?
7. Can someone post Radeon 9700 Pro’s spesification and its meaning? Like what is core speed and so on… This one can be ignored cause after second thought, this will be pain in the ass for the poster but I appreciate if anyone’s willing to post this
8. Sorry missed this one: What’s the effect of having more Vertex shader and more Pixel Rendering Pipeline?

I’ve search over the net about those features on the net but there’s no plain English on websites…I really need help, hope anyone can help me. I know this is very annoying and da** long question…Just a hope…

Thanks..

PS: I’ve searched Tomshardware and Anandtech, Vision Engineer etc etc but no result….

:confused:

Heh? I was kinda confused too, did you suggest me to change my topic? Well, I can't do that. I've submitted the topic which not allowed to change a few weeks ago. And I guess there's not much time left if I change my subject.

Atomic, thanks for the link but that's not adequate enough for preparations. My class was very eager about discussion like this so I guess I have to prepare better than that.. Many thanks anyway...

>1. Vertex Shader
What’s the use of this feature? As I know, it’s for counting geometries needed to render a graphic. But is that all? I read ATI said that 4 vertex parallel shader can process one vertex per clock. What does that mean?

Vertex shaders are used for increased graphical quality in certain games that support them (Neverwinter Nights and Morrowind for example). Such games are few and far between at the moment, but we will see them in the future.

>4. What’s anisotropic filtering?
This is the most confusing feature, I think. What’s with the angle of viewer and things? Don’t get it?? And if I can get some clear pictures of the differences between Radeon’s AF and Geforce’s AF that’ll be great, since I’ve downloaded some pictures from the net and none of them showed a clear difference

Anistropic filtering is a method to sharpen textures which are oblique to the viewport. The GeForces and Radeons AF comparison? The GeForces use a slower but more accurate method, producing a slightly better qualty image. The Radeons have an optimised method whiuch produces lower quality. However, the actual difference in quality is negligable.

>5. How’s the work way of N-patch? / Truform?

Games that support them allows you to add polygons to models.

>6. What’s the plus minus using Radeon 9700 Pro compared with Geforce 4 Ti 4600?

ATi's OpenGL drivers aren't as complete as nVidia's. Fortunately this only really seems to affect PSX emus.

>8. Sorry missed this one: What’s the effect of having more Vertex shader and more Pixel Rendering Pipeline?

Faster Vetex and Pixel shader effects.

1. Vertex Shader

I don't really know much about this but I believe vertex shaders are used for programming effects on vertexes. Here's a quote from Anandtech:

Quote:

In a programmable GPU these initial vertex processing stages are very flexible in that short vertex shader programs can be written to control a number of the characteristics of the vertices to change the shape, look or behavior of a model among other things (e.g. matrix palette skinning, realistic fur, etc..)

They also seem to have a direct effect on the triangle transform rate. Here a link on shader technology that might help you. It's primarily for game developers but might have information to shed some light on vertex and pixel shaders for your presentation. The Radeon 9700 Pro has 4 vertex shader units, as opposed to the 2 on the GeForce 4 Ti and Radeon 8500. The vertex shaders are also v2.0 (DX9 specification), which allow for a truly programmable environment. While the previous v1.0 and 1.1 were procedural (top to bottom) v2.0 allows loops and conditionals. The maximum size of instructions has also been increased to 1024 from 128.

2. Vertex and Pixel Shader

In a very basic sense, vertex shaders are used to program effects on vertexes while pixel shaders are used to program effects on pixels. Yeah, a no-brainer answer, right?

Anyways, refer to the link above. Vertex shaders and pixel shaders on the Radeon 9700 are both v2.0, allowing for more flexibility and capabilities.

3. What’s the use of Pixel Rendering Pipeline?

The pixel rendering pipeline is, well, the unit used to render a pixel. It encompasses many different functions and is responsible for transforming the vertex data from the T&L unit into actual graphics. The number of rendering pipelines and the core clock speed will ultimately determine the performance of the card. Think of it as the multiplier on a CPU. The CPU Mhz speed is composed of the front-side bus times the multiplier. The higher the multiplier the faster the CPU can run. In the same sense the higher the number of pipelines the more pixels the videocard can process. The Radeon 9700 has twice as many pixel pipelines (8) as the GeForce 4 Ti (4), therefore it has twice the pixel fill rate (how many pixels it can process) at the same clock speed. Unlike a CPU though the pipelines are a part of the chip design and etched into the chip. You cannot add more pipelines, although they can be disabled. The pixel pipelines make up most of a GPU. With the Radeon 9500 ATI removed 4 of the 8 pipelines from the R300 and by doing so the transistor count was reduced by over 50 million (almost as big as the GF4 Ti itself which is about 64 million).

4. What’s anisotropic filtering?

Anisotropic filtering is a method to remove the anisotrophy (blurring) left by bilinear and trilinear filtering. As objects get further and further away the textures tend to blur. Anisotropic filtering is an algorithm to lessen the blurring and sharpen the graphics. The Radeon 8500/9000/9500/9700 series use what's known as "adaptive anisotropic filtering" where it only uses the required level of AF for optimal graphics. It has a much lower performance impact while still maintaining the same image quality as the GF4. I have some very good screenshots of anisotropic filtering at home, I'll post them as soon as I can. Also, ChrisRay and I took some comparative shots of AF (me: Radeon 9000 Pro, him: GeForce 4 Ti 4200) so they might come in handy as well.

5. How’s the work way of N-patch? / Truform?

I don't know about n-patch but Truform was technology to smoothen the look of blocky polygon objects by "filling in" polygons for the blocky areas. It doesn't work too well with a lot of software though and the feature is left off for most of ATI's current products.

The Radeon 9700 review at THG would indicate that N-patch is a feature of the vertex shader to allow various transformation effects on vertices. It can be used to create a more detailed and complex look without adding more vertices.

6. What’s the plus minus using Radeon 9700 Pro compared with Geforce 4 Ti 4600?

Pros

Fast performance overall
Fast Full Scene Anti-Aliasing
Fast Anisotropic Filtering
Full support for DirectX 9

Cons

Less optimized drivers
Bad multi-texturing capabilities

7. Can someone post Radeon 9700 Pro’s spesification and its meaning?

Core clock: 325 Mhz

This is the speed (in Megahertz) that the GPU core runs at. Think of it as the front-side bus of a CPU.

Memory: 620 Mhz (310 DDR)
Memory width: 256-bit
Max memory: 256 MB

This is the speed (in Megahertz) that the memory chips run at. The Radeon 9700 Pro uses DDR memory with four 64-bit memory controllers, offering a theoretical memory bandwidth of 19.8 GB/s (without memory saving algorithms), almost twice that of the GeForce 4 Ti 4600 (10.4 GB/s). The maximum memory size is 256 MB, although most cards will come with 128 MB. The 256-bit DDR memory of the Radeon 9700 Pro is about equal to 1.24 Ghz 128-bit DDR (or DDR2) memory (used on all other cards, including the upcoming GeForce FX).

Pixel pipelines: 8
Textures per pass: 16
Pixel fill rate: 2.6 GPixels/s
AA fill rate: 15.6 billion AA samples/s

The Radeon 9700 Pro comes equipped with 8 128-bit floating-point pixel pipelines (as opposed to the 4 64-bit integer pipelines on the GF4 and Radeon 8500; each pipeline consisting of about 12-13 million transistors). Combined with the clock speed of 325 Mhz and you get a pixel fill rate of 2.6 GigaPixels/s. The Radeon 9700 Pro can also pass 16 textures per pass (as required by the DirectX 9 specifications). By comparison the GeForce 4 Ti can pass 4 textures per pass and the Radeon 8500 can pass 6. However, a weakness with the Radeon 9700 Pro is its multi-texturing capabilities. Due to size and transistor constraints ATI only equipped the R300 with 1 TMU per pipeline (the GF4 has 2). Therefore it suffers in multi-texturing situations (pretty much all games use multi-texturing now).

Transform rate: 325 million triangles/s

Due to its 4 vertex shader units and a powerful triangle setup engine the Radeon 9700 Pro boasts an amazing 325 million triangle/s transform rate. This is more than twice as much as the GeForce 4 (logical, since the GF4 only has 2 vertex shader units).

Die: 0.15 µon

The Radeon 9700 Pro is built on a 0.15 µon (150 nanometers) manufacturing process. As a result the chip is pretty large (consisting of about 110 million transistors) and requires an extra power supply, as it exceeds the AGP 3.0 power specs. Most people thought you'd need a 0.13 µon process for DX9 but ATI proved otherwise. The GeForce 4 also uses a 0.15 µon process. The upcoming GeForce FX from Nvidia will be using a smaller 0.13 µon process, which will allow for higher clock speeds.

AGP: 1x, 2x, 4x, 8x

The Radeon 9700 Pro is an AGP 3.0 part and has support for AGP 8x. It's the first product to have support for it, although AGP 8x doesn't really add any benefits to modern 3D gaming. AGP is backwards compatible so the card also supports 4x and lower multiplier settings.

8. Sorry missed this one: What’s the effect of having more Vertex shader and more Pixel Rendering Pipeline?

Vertex shaders: Faster vertex shader capabilities, more triangle throughput.

Pixel pipeline: Explained in my answer about pixel pipelines. More fill rates and better performance.

Okay, here are a couple of pictures of anisotropic filtering and its impact on graphical quality. These shots were taken in Max Payne at 1024x768x32.

The first one is a shot without anisotropic filtering. It's rendered using plain bilinear filtering. Notice in particular the blurring on the ground and walls.

**Demigod** · January 14th, 2003

This second shot was taken with 16x (128-tap) anisotropic filtering. Notice that the blurring has all but disappeared, leading to nice, sharp textures even at far distances. This shot was taken on my Radeon 9000 Pro, which can do very fast AF (less than 10% performance hit at 16x).

As for comparative GeForce 4 Ti shots ChrisRay and I took some comparative shots before. I think he has a page with the shots on them. You can ask him about that. Honestly though, there's not that much difference, if any at all. They both look pretty much the same at all AF levels.

Oh, and feel free to use these shots for your presentation if it'll help. I found these shots to be a very good example of anisotropic filtering.

beckham_m7u · January 14th, 2003

thanks,. but it seems that I have another probs here:
1. I thought NVidia does its AF all the way till the distance so why's in Demigod's shot he said that Radeon's AF still clearly seen till far at distance? So what's the difference? Nvidia's AF is full one while ATI doesn't filter all the graphic?

2. What's the use of _X AF ?? eg: 4X AF, 8X AF
3. Radeon's said have a fast AF. What's that for?

Thanks

can anyone describe details and the functions of:

a. texture per pass
b. multi sampling and super sampling (I know these are used for Anti aliasing) but what about the definitions?

Can anyone tell me where to get a comparative table between Radeon 9700 Pro, 8500 and GF 4 Ti 4600?

I know these are very troubling but please help me if u can..
thanks

edit:in case i'm walking along a tunnel...which is the part of the tunnel will get filtered (with AF) the most? and which one the least?

There are a variety of anisotropic filtering levels, from 2x to 16x. The higher the level of AF the more filtering it'll do for textures at a distance. The difference between Nvidia's method and ATI's method is that Nvidia rendering everything at the same level. If you're running at 8x AF on a GeForce 4 it'll render everything at 8x. ATI's "adaptive" anisotropic filtering uses different levels of AF, depending on the distance of the textures from the player's angle of viewing. Textures closer to the viewer will be filtered with a lower AF level (since filtering them with a higher level will not improve quality much) while textures further away will be filtered with a higher level. At 16x AF on a Radeon 8500/9000/9500/9700 it'll vary the filtering from 2x - 16x. Textures closer will be filtered at 2x, textures at moderate range will be filtered at 4x and 8x, while textures far away will be filtered at 16x. By only using the required level of AF ATI can save a lot of processing power while still maintaining respectable quality. 8x AF will have a huge (40%) performance hit on a GF4 Ti while 16x AF on a Radeon 9700 will only have about a 7-10% impact. Nvidia will also be implementing adaptive AF on their upcoming GeForce FX cards.

Multi-texturing is applying multiple textures for a rendering process. Most games nowadays use multi-texturing. Multi-texturing will stress the texturing capabilities of the videocard. Many videocards nowadays come with multiple pipelines and texturing units. A card like the GeForce 4 Ti has 4 pipelines with 2 texturing units each (8 texture units total). In a multi-texturing situation the card can utilize its extra pipelines and TMUs to render multiple textures in a single pass. A card with only 1 pipeline and 1 texturing unit will have to go through several passes to render multi-textured graphics.

on the differences Demigod told me (I own a debt on him

), GF 4 Ti 4600 have a little more memory (650 mhz) compared with radeon 9700 pro (620 mhz). So why's the Radeon still have a chance winning on GF 4 Ti 4600? does the memory mean nothing?

and I thought the max memory for Radeon 9700 pro was 128 MB how come it's 256 MB? is it upgradable?

What’s with the angle of viewer and things? Don’t get it?? And if I can get some clear pictures of the differences between Radeon’s AF and Geforce’s AF that’ll be great, since I’ve downloaded some pictures from the net and none of them showed a clear difference Anistropic filtering is a method to sharpen textures which are oblique to the viewport. The GeForces and Radeons AF comparison? The GeForces use a slower but more accurate method, producing a slightly better qualty image. The Radeons have an optimised method whiuch produces lower quality. However, the actual difference in quality is negligable. >5. How’s the work way of N-patch? / Truform? Games that support them allows you to add polygons to models. >6. What’s the plus minus using Radeon 9700 Pro compared with Geforce 4 Ti 4600? ATi's OpenGL drivers aren't as complete as nVidia's. Fortunately this only really seems to affect PSX emus. >8. Sorry missed this one: What’s the effect of having more Vertex shader and more Pixel Rendering Pipeline? Faster Vetex and Pixel shader effects. __________________ >Site Live< Pop over to my site for help with setting up PSX emulators.

beckham_m7u Luv Hyolee Join Date: Apr 2001 Posts: 551	thanks,. but it seems that I have another probs here: 1. I thought NVidia does its AF all the way till the distance so why's in Demigod's shot he said that Radeon's AF still clearly seen till far at distance? So what's the difference? Nvidia's AF is full one while ATI doesn't filter all the graphic? 2. What's the use of _X AF ?? eg: 4X AF, 8X AF 3. Radeon's said have a fast AF. What's that for? Thanks __________________ "Hyolee is my dahling"

ChrisRay Guest Posts: n/a	Here are some comparative shots me and Demigod made of Full Screen Anti Aliasing and Anistropic Filter comparing NVidias methods and Ati's methods. Give them a look. personally the difference just isn't there to justify the performance loss right now http://chrisray.blkhawk.net/test/ Geforce 4 Ti http://chrisray.blkhawk.net/test/demi/demi.htm Demigods Radeon 9000 Pro.

beckham_m7u Luv Hyolee Join Date: Apr 2001 Posts: 551	here's another one: can anyone describe details and the functions of: a. texture per pass b. multi sampling and super sampling (I know these are used for Anti aliasing) but what about the definitions? Can anyone tell me where to get a comparative table between Radeon 9700 Pro, 8500 and GF 4 Ti 4600? I know these are very troubling but please help me if u can.. thanks edit:in case i'm walking along a tunnel...which is the part of the tunnel will get filtered (with AF) the most? and which one the least? __________________ "Hyolee is my dahling"

beckham_m7u Luv Hyolee Join Date: Apr 2001 Posts: 551	uh Demigod, what about anti aliasing's method: multi sampling and super sampling. Guess I have to put that on my paper __________________ "Hyolee is my dahling"

beckham_m7u Luv Hyolee Join Date: Apr 2001 Posts: 551	another one on the differences Demigod told me (I own a debt on him ), GF 4 Ti 4600 have a little more memory (650 mhz) compared with radeon 9700 pro (620 mhz). So why's the Radeon still have a chance winning on GF 4 Ti 4600? does the memory mean nothing? and I thought the max memory for Radeon 9700 pro was 128 MB how come it's 256 MB? is it upgradable? __________________ "Hyolee is my dahling"
