Talk:Accelerated Graphics Port

message: :The article is also missing the advanced features of 2.0 and above (FastWrites, etc).
:However, I doubt anyone else here is going to expand id. Ah well, time to take some photos of my motherboard and graphics card... the latter can be dumped into Radeon as well...

message: Can someone descripe AGp 1.0, 2.0 3.0?
Also explain AGP multiplier (in BIOS sense).
Any photos of the different AGP connectors would be good.

message: The article does not mention that AGP followed the footsteps of Vesa Local Bus (VLB) common on 486 era systems, or that it was first introduced on Socket 7 (second gen. Pentium) and Slot 1 motherboards (early Pentium II systems, IIRC), or that OS support was first introduced in Windows 95 and NT 4.0 (I'm guessing here).  MaxEnt 01:44, 9 April 2006 (UTC)

message: It was kind of disgusting yet pertinent, but then to my shock I discovered an Agpgart page so I moved my Linux-centric footnotes there.  MaxEnt 04:30, 9 April 2006 (UTC)
thread_title: AGPGART excised

message: Many AGP 1x cards were merely an existing PCI design reworked to plug into an AGP slot and do not use AGP texturing or any of the other advanced AGP features.
:Running NT on a Matrox Mystique I didn't pay attention to that at the time.  One angle I would like to see further developed in this article is a sense of technologies introduced into the PC industry and their life story.  
:*How long was the PC universe pushing the new technology with no immediate benefit to the end consumer?  
:*Which advanced features ended up making a difference, at what point, under what circumstance?
:Another issue which was still big at the time was BIOS level PCI bus enumeration and Plug and Play/Pray factor which was almost beginning to work around the time that AGP came along.  
:*Did AGP contribute anything toward cleaning this mess up?  
:*Is there any distinction in the IO port, DMA, or interrupt resources required of an AGP card as opposed to a PCI card?  
:The material I added was just enough notes and keywords that someone motivated could fill in more of the blanks themselves.  AGP is well on its way to becoming a historical footnote.  My feeling is that an encyclopaedic treatment should read more like a good history article and less like a dictionary of AGP ratifications (which is excellent material in its own right that I would never remove). 
:The most interesting story to me is how the industry shifted demand to a new design that didn't benefit the end user until the *second* PC they purchased featuring the new technology.  When the AGP enhanced video cards finally showed up, did they actually work to their full potential in the AGP systems sold in the first six months after introduction, or did you have to replace your system board at the same time with one designed and tested to work to full potential with the generation of video cards that finally supported the new feature set?  From a school of business perspective, the most interesting thing is how often the PC industry managed to get away with selling some new technology to the end user that promised to enable the future that ended up proving incompatible with the promised future when it finally arrived.  See also: Bus Mastering DMA, USB, MMX, HDTV, HDMI, RDRAM, DDR, DDR2 all of which sucked for the early adopters.  It's not like we (the gullible public) have learned much.

thread_title: Early AGP cards

message: I'm getting a little off topic here, but take a look at this: 
http://www.pcguide.com/ref/mbsys/cache/char_Cacheability.htm
*The amount of RAM that the system can cache is very important if you are going to be using a lot of system memory. Almost all modern fifth generation systems can cache 64 MB of system memory. However, many systems, even newer ones, cannot cache more than 64 MB of memory. Intel's popular 430FX ("Triton I"), 430VX (one of the "Triton II"s, also called "Triton III") and 430TX chipsets, do not cache more than 64 MB of main memory.
*The keys to how much memory your system can cache are first, the design of the chipset, and second, the width of the tag RAM.
*The only mainstream Pentium chipset to support caching over 64 MB is the 430HX "Triton II" chipset by Intel. In actual fact, caching over 64 MB on this chipset is considered "optional"; the motherboard manufacturer has to make sure to use an 11-bit tag RAM instead of the default 8-bit. The extra 3 bits increase cacheability from 64 MB to 512 MB
*Pentium Pro PCs use an integrated level 2 cache that contains the tag RAM within it, so none of this is really a concern for these machines. The Pentium Pro will cache up to 4 GB of main memory, basically anything you can throw at it. The Pentium II uses an SEC daughtercard. It has the same general architecture as the Pentium Pro, but due to a design limitation will "only" cache up to 512 MB.
Around the time that AGP was introduced, the industry was still busy shaving three bits off a tag RAM at a point in time where cheaper memory was by far the most cost effective upgrade for any PC with a graphical desktop.  That was the reason I got into the PPro early: fewer cripple bits.  
People who knew that the early AGP designs didn't help you much ended up buying AGP systems regardless in order to gain other advantages from less crippled chipsets.  Some of those Pentium era chipsets (I'm trying very hard not to type cripsets) already had Steve Yzerman's late career knee cartilage the day they were first introduced.

thread_title:  Cripple Bits 

message: I would like someone to find the max current (amps) that can be delivered through the AGP interface.  I see this information varies on web pages.  A total wattage would also be benificial.
I'm not sure, but it is at least 19Amps, as there are AGP editions of PCI-e cards that use that much, such as X1950s.Alexander 06:57, 20 August 2007 (UTC)

message: "AGP is slowly being phased out in favour of PCI Express."
It's actually happening very quickly...
: In new PCs, yes. But a Valve software survey of people running their games in March showed only 26% using PCI-Express systems: http://www.steampowered.com/status/survey.html Mark Grant 21:36, 24 July 2006 (UTC)

message: I believe that the current lists look a lot better than lengthy text will look, and are also much more readable.
—The preceding unsigned comment was added by 67.165.235.73 (talk • contribs).
:The 'Hardware and Software Adoption' section should certainly be rewritten into a few paragraphs of text. The list at the end of 'Versions of AGP' could probably also be rewritten into a subsection. That list isn't even introduced - it has no context. Some of the sections could be rearranged too, 'Hardware and Software Adoption' could become 'History' and moved to the top. --Imroy 07:03, 17 November 2006 (UTC)
thread_title:  Lists and sections 

message: I warned you, this is very nitpicky. This article states that AGP1x is "A 32-bit channel operating at 66 MHz resulting in a maximum data rate of 266 megabytes per second (MB/s)". However, 4 bytes * 66 MHz does not equal 266 MB/s, but rather 264 MB/s. Is the maximum bandwidth actually 264 MB/s, or is the frequency rounded in the article, or is there something I'm missing? (The official spec is very hard to read.)
: 66 2/3 MHz. 66.666666667 MHz. So, technically, it's 267 MB/s. But, for whatever reason (maybe the typical clock fluctuation) it is stated as 266 MHz. --Swaaye 04:15, 8 February 2007 (UTC)
thread_title:  nitpicky question about speed and bandwidth 

message: hi, 
thought this might help develop this wiki page - I am no expert in video graphic cards - but I thought this might help - it explains the difference in AGP version 2.0 and 3.0 
In layman's terms AGP 2.0 is AGP 2x and AGP 4x.  While AGP 3.0 is an AGP 8x or 4x.

message: Is this a misprint: the HP AlphaServer GS1280 has up to 64 AGP slots? Why would any computer need 64 video outputs? Danceswithzerglings (talk)
:No, it's not a misprint. It's right there on the cited datasheet. As to what they'd be used for, I can only imagine two scenarios:
:# A multi-user setup where everyone needs accelerated 3D graphics. The datasheet does talk about partitioning the system, so it could be a kind of thin-client setup. An awfully expensive one though.
:# A large visualisation setup with a huge tiled display. Each AGP graphics card drives a screen or projector. With up to 64 Alpha's and 512GB of RAM, this system could have some serious grunt and work through really large datasets e.g seismic survey data for oil exploration.

thread_title:  64 AGP ports 

message: Some laptops come with an "AGP" port (eg. Dell Inspiron 8100) but this is obviously incompatible with desktop AGP. Does this special port have a specific name? How dies it differ electrically from the desktop version? 2fort5r (talk) 19:27, 12 July 2009 (UTC)
replies: text: Laptops can use AGP in the same way they use PCI and ISA - to connect the various chips together. It's the same with all the "on-board" functionality of modern desktop motherboards e.g IDE/SATA, audio, network, USB, etc. They connect directly to the buses/interconnects, without the edge connectors. --Imroy (talk) 08:21, 13 July 2009 (UTC)

text: Ah, ok. I wasn't familiar with this laptop. It could be specific to Dell - they could have chosen a suitable connector, devised a pin-out, and had the various manufacturers make parts. It doesn't have to be part of a standard. Large companies are known for creating their own non-standard connectors. Sorry I can't be of more help. --Imroy (talk) 19:26, 13 July 2009 (UTC)
