AGP or Accelerated Graphics Port was the most popular and common interface for connecting graphics cards on motherboards. It was a high-bandwidth channel and remains on the motherboards for quite a long time. Another interface was PCI but it was a slower channel and not many graphics cards were made for PCI slot in the past.
Generally, AGP came in two variants, first was the AGP 4x which has lower bandwidth and the second one was the AGP 8x which has double the bandwidth of AGP 4x. AGP 4x has a maximum transfer rate of 1066Mb/s whereas AGP 8x has 2133 MB/s. There were also AGP 1x and AGP 2x interfaces but they were very slow and not used that frequently. AGP slot is smaller in size than the PCI and other graphics card interfaces. You won’t see AGP slot in the current generation motherboards because today PCI Express x16 is used for connecting graphics cards which has much higher bandwidth compared to the older AGP graphics card interface.
In older motherboards, you may be able to find AGP slot and if you wish to upgrade the graphics of your older PC then you will need an AGP Graphics Card for it. AGP graphics cards are nearly extinct in production but you can still find some good AGP Graphics Card in the market or online for your older PC or server. To help you out on this, here I am providing you the list of best available AGP graphics cards that you can buy online.

U forget HD 4670 AGP
Its availability is an issue.
Hello,
I have an Asus A8V-MX serial- 5CM0AD164856 MB.
Successfully updated to windows 7 pro by going to a ATI RADEON AH3450/DI/512MD2(LP)
graphics card. But the HD AUDIO CONTROLLER driver didn’t install due to Not Enough Resources
code 12.
I have 2GB memory as well…..maximum for this MB.
ASUS support recommend I get another video card like HD4350 or above to resolve this
driver problem.
The video works and don’t notice any problems except youtube videos aren’t smooth!
I’ve updated BIOS to current version.
I also bought a newer CPU which is AMD Athlon 64 X2 4400 2.2 GHz dual core. Happy with that speed improvement.
I going to install Windows 10 next.
What do you think about that HD audio controller problem? What is causing it?
I only use my computer for email, reading news with videos, no gaming except pinball.
Have a 450 watt power supply…fyi.
I think it is a driver issue because the card is very old and lacks support for modern operating systems. I don’t recommend installing Windows 10 on this hardware with only 2GB RAM and older video card.
Is a 128 bit faster than a 64 bit card even though the GPU would be the same for both?
Yes, 128-bit will be faster if GPU & memory speed is same on both the cards.
You forgot the 3650?
It is hard to find these days.
My old PC have 2slot DDR ram..can graphic card ddr2 run on the DDR ram ?
Yes you can run DDR2 graphics card on motherboard with DDR RAM because there is no correlation between graphics card VRAM and motherboard RAM.
Tq mr verma!
I wrongly question u.
This is my question.
My motherboard is old. 1 slot for graphic card agpx18 and 2 slot for standard slots.
Can graphic card ddr2 attach to standard slot?
An AGP graphics card can fit only in AGP slot and a PCIe graphics card in PCIe x16 slot only. What standard slots are you talking about?
Hi.i have an ASRock k8 combo-z motherboard and I wanted to know that can I use the 512mb graphic cards that are named in here on that?
I have an Amd athlon 64 x2 4400+ cpu and 2gb ddr400 ram.
And should I install a Windows XP 64bit for this graphic and cpu?
Yes, you can use 512MB graphics card with it and it is better to use Windows XP (32-bit).
Thanks for your really fast answer you are really really amazing.but only three more questions:
1.can I install 1024 mb graphics too?
2.how can I update and check my bios version?and what is the needed version for installing the amd athlon 64 x2 4400+ on my motherboard?
3.what power will be useful for this system?
Thanks a milions.
1. Yes you can install a 1GB card.
2. You can check the current BIOS version using CPU-Z or HWiNFO tools (https://www.hwinfo.com/). You can download the new BIOS at http://www.asrock.com/mb/ULi/K8%20Combo-Z/#BIOS
3. A good 300W power supply is enough for your system.
which is best for ASRock 775i65G Board
Is quadcore conpatible but not work without video card
Any AGP card you can find will work. I think EVGA GeForce 6200 512 MB DDR2 can be found this time.
I want to run Flight Simulator 2002 on my XP computer, but I don’t get very good graphics. I need to upgrade my video card I am sure. I have an HP Pavilion a600n computer with no changes up to this point. What kind of card do I need? FYI, when I run the program now, I get video that seems to hesitate and the range is very short, as far as distance being seen is concerned. I have tried different settings on the game itself but to no avail.
Can you please list your specs?
AMD Athlon XP 3000+, 2.1 Ghz, 512 KB Cache, 512 KB Ram, memory speed 333 KHz, integrated graphics, VIA UniChrome shared video memory (UMA), VGA.
I think GeForce GT 1030 (GDDR5 version) would be good for you.
Would that make my graphics smooth? I only use this particular computer to play my simulators (flight and racing), and do word processing. I can’t get any of my games to work on my windows 10 computer. The graphics on the flight simulator box is great, but on my computer, it is choppy and rather blah.
One thing I want to confirm, does your motherboard have a PCIe x16 slot?
I have no idea which slot is which. My specs say my main board is VIA UniChrome KM400A. Under slots it says 2 free PCI, 1 free DIMM 184-pin, 1 free AGP 8x.
I have checked my computer and there is NO pic e slot. Only AGP 8x.
It means you need a AGP graphics card which is very hard to find these days.
Thank you for all your help.
I’m just tinkering on an old pc I had in storage. Its a rev:1.3 mobo, 8 ram, and I have a pentium 4 extreme 3.2 on the way. What is the most gpu I could get from a 720p 60hz monitor?
I did not get you completely. Are you looking for a compatible AGP card?
thank you for getting back to me… yep, I think they kept making AGPs until like 2009ish , maybe. But I don’t know if the latest agp models that were made would bottleneck the cpu I’m putting in it. Basically I have a 7 and 10 year old and I don’t want them playing Minecraft on my personal rig. I just don’t have much knowledge of the agp cards. Thanks for the help!
Well, AGP cards are difficult to find these days. I don’t see any point in getting a graphics card for such an old system unless you are facing some hardware issues with your onboard graphics. However, if you are keen on upgrading to a discrete card then I think GeForce 6200 or GeForce FX 5200 are good choices.
I can find them on ebay, just funny that the AGP cards are actually about 5 times more than their PCIe counterparts at the time. I just wanted to make sure that my kids could play Minecraft, Cuphead, SonicMania, simple stuff like that. I don’t want them to mess my PC up since I use it for design work and for more intensive gaming.
I found this old PC I had back in college and decided to gut it and spare a few parts for a cheap build my kids could use for very light gaming. I found a really good deal on a refurbed Pentium4 Extreme Edition 3.2 CPU for it. I just didn’t know if an IBM rev:1.3 motherboard from 2001 could push a GPU from say 2009… Thanks again for your help.
https://ark.intel.com/content/www/us/en/ark/products/27489/pentium-4-processor-extreme-edition-supporting-ht-technology-3-20-ghz-2m-cache-800-mhz-fsb.html. Is this your processor?
Yes sir.
Ok. Well, I think adding a GPU won’t benefit you in the games you have mentioned because you will be limited by your CPU performance.
Thanks, I’ll see what happens with a ATI HD 4870 I think. I appreciate all of your help.
You are most welcome!
You definitely should have bought a Sapphire Radeon HD3850 or HIS IceQ3 Turbo HD3850 AGP instead… That is the “king” of all the AGPs ever made… With 256 bit architecture and 512 MB of GDDR3 Memory…
I’m also using an Intel Pentium 3.4 Extreme Edition on an ASUS P4C800 E-Deluxe and I think you are limited with the 128 bit architecture of the Radeon 4870… Switch to a Sapphire Radeon 3850 AGP if you can find on Ebay or any second hand shop… 😉
Hi. I have a comment and a question.
The comment is that I have an old desktop PC with INTEL D865 PERLL motherboard, INTEL PENTIUM 4 microprocessor (3Ghz), 3.5 GB DDR400 RAM, an EVGA GeForce 6200 256mb GPU, which I always used with Windows XP … and I installed Windows 7 a few weeks ago, but the video card freezes randomly and I have to restart the PC by force.
Searching the web I found out that many people who have GeForce 6200 have similar conflicts when installing Win7 and even though I tried everything they propose as a solution, I couldn’t get it to stop freezing from time to time.
The question then is: which AGP board (with VGA and DVI/HDMI outputs) would you recommend, that would be fully compatible with Win7 and would not produce driver conflicts or any other problem?
(I live in Argentina and you can get a lot of old stuff searching the web, so don’t hesitate to recommend even if you think it’s hard to find nowadays).
Thank you very much.

Well, I am not sure but maybe Radeon HD 4670 AGP because it was launched in 2009 and is relatively newer than other AGP cards that I can think of.
Thank you very much for the prompt response.
I was researching and it seems that the RADEON models that support DirectX 10.1 are only available in PCI-E, at least in Argentina. I will have to investigate further.
Any suggestions other than RADEON HD 3xxx, 4xxx?
I would say GeForce 7600 GT AGP.
The true answer was the ATI Radeon 3850 AGP… Sapphire or HIS brand … (If you can find) 😉
Because of its 256 bit architecture… 512 MB GDDR3 Memory and Direct X10.1 support 😉
Try Ebay.. Or second hand shops…
That model does not exist in my country … ha,ha
Besides, I saw that it only supports DirectX 9.c.
The striking thing is that it uses the same driver as the GF 6200 I have.
My PC (as long as the graphic card doesn’t freeze) works perfect with Windows 7, even faster than when I had Windows XP.
Would it be a good idea to try to update the firmware of the card?
Thanks again for the help 🙂
I would not suggest fiddling with the firmware of such an old card. What driver version are you using? Try this driver and monitor https://www.nvidia.com/en-us/drivers/results/49892/
The first driver I installed was 309.08 (the last one that came out), but since it gave problems, after researching, many people said on the web that they solved the issue with the latest driver exclusively for AGP cards (96.85 winVista), and that is the one I have installed today.
Other people also recommended 307.83.
Why do you recommend 306, any particular reason?
And what do you mean by “monitor”?
No particular reason as such. By monitor, I mean monitoring the card’s stability using the driver.
Ah, OK.
As soon as it freezes again I do the driver installation.
I’ll let you know how it went.
Ok and always use DDU to uninstall graphics driver completely https://graphicscardhub.com/display-driver-uninstaller-ddu/
OK, a while ago the PC froze.
– I uninstalled drivers with DDU.
– I rebooted and installed the 306 you suggested.
– In less than 5 minutes the PC froze again.
– I rebooted and uninstalled drivers with DDU.
– I rebooted and reinstalled the 96.85 driver I had.
– I rebooted and it booted back to normal.
– I rebooted again just to try to get it to boot back to normal, but this time, as soon as it started it froze.
– I rebooted one more time, it booted back to normal and here I am typing.
EVERYTHING IS STILL THE SAME 🙁
Ohh, I think you have to stick with the previously working driver only.
It’s a complicated subject … all the drivers I tried work but eventually the PC freezes.
Maybe I should have stayed with Windows XP … ha,ha,ha
Hi guy, can I ask the gpu that u mention geforce fx 5200 (agp slot x8) can fit msi pm8pm-v motherboard?
Any types or brand of gpu is similar to radeon x700 (PCIe slot) gpu?
Thanks so much
I think GeForce FX 5200 (agp slot x8) can work with your motherboard.
OK thanks, is it work perfectly?
how about any gpu can replace radeon x700? I got 2 old pc, now trying to reuse back. Thanks
I think it should work fine. Another option would be GeForce 6200 AGP and it is better than FX 5200.
Hi guy, sorry for keep bothering.
Nvidia geforce 9500gt and
AMD radeon HD8490 1gb ddr3
is it suitable for EPoX EP-9NPA3J – motherboard? This gpu seem like to advance for my motherboard. My current radeon x700 spoil, I looking for replacement thank.
I don’t think they come with an AGP interface.
EPoX EP-9NPA3J this motherboard board is come with PCIe slot
I have an ATI Radeon HD 3450 coming soon. I bought it because I saw it on this list, and I found it on eBay for a really good price compared to what other ones were priced at. I’m planning on installing it in my Asus P4P800 motherboard, with a Pentium 4 2.6ghz. I also have a new set of 2 GB of ram coming. Thanks for this guide, or I wouldn’t have known what to look for.
You are most welcome!
I’m struggling to find proper drivers for it. Do you by any chance know where to find drivers for windows 7 and windows xp? All the ones I’ve tried don’t work at all.
Check https://www.amd.com/en/support/graphics/amd-radeon-hd/ati-radeon-hd-3000-series/ati-radeon-hd-3450
Those are for the normal PCIe cards, not the agp variant. I ended up finding them through some internet forums digging, and unfortunately while the Windows XP ones work amazingly, the Windows 7 ones are extremely buggy and don’t work right at all. They work beautifully if you don’t do anything too demanding, but if you try to do anything that’s demanding, anything using full 3D graphics or any video playback, it gets all sorts of graphical glitches, and then totally craps itself and the graphics driver locks up. Sometimes it restarts the graphics driver and fixes itself, but most of the time I have to restart the computer, and if you’re still doing any of those things when it does fix itself, it is very likely to break again.
Check these also http://www.oldversion.com/windows/ati-catalyst-drivers/
https://drivers.softpedia.com/dyn-search.php?search_term=Amd+catalyst+agp+hotfix&p_category=0&p_lastupdate=0&p_sortby=0
These are the drivers I found from digging. The xp 32 bit works just fine, the Windows 7 32 bit though, is the glitchy one. I’ll see if the second link you sent works, but this is what I was able to achieve so far.
I have an old computer than I only use for my old flight simulators such as Microsoft Flight Simulator 98, which was made for Windows 95. And several other of my old flight sims that were made for Windows 95. The computer is a Compaq Presario S3310CL, Micro ATX, with Windows XP, ver 2002, with service pack 3. Motherboard is a MS-6577 ver 2. Processor is a Pentium 4 (Northwood) with 2.53 GHz. It is 1.5 volt. It has 504MB of RAM. Also the chipset is Intel 845. I do not have a graphics card installed in the AGP slot. I downloaded a manual for the motherboard and it said it supports 1.5v AGP 4X interface. (But warned not to use 3.3v AGP 2X interface) I see lots of AGP cards on Ebay but not sure which to go with. My system is a 32-bit and many of the cards on Ebay are for 64-bit systems. And many of the cards for sale do not show which bit they are. My question is do you think a graphics card will help with these old flight sims and how do I know before I buy it, whether a particular card is 32-bit or 64-bit, and will a particular card work with my system or not. Also which do I go with, the 2X, 4X or 8X card. Thanks
The bit (64-bit etc.) for graphics is for the graphics card’s memory and has nothing to do with 32-bit or 64-bit Operating Systems. You can safely go with AGP 2.0/AGP 3.0 (x4/x8) graphics cards. I think even entry-level AGP graphics cards like GeForce FX 5200 and GeForce 6200 can significantly boost your computer’s gaming performance.
Thank you Akshat. Understood. I will take that advice and shop around. I also should probably buy some more RAM and a larger hard drive. From what I read in the manual, my mother board will support 2GB of RAM and from what I understand I should get 2 sticks of 1GB each. Is it the DDR Dimm I will need and does it matter if it is the single or double sided type. And one other question, what size new hard drive should I go with, and the solid state type or no. Thanks again
Get two sticks of 1GB each for dual channel mode operation for better performance (single/double-sided does not matter). Also, ditch the hard drive and get a 2.5-inch SATA SSD. For SSD, I suggest Samsung Evo 860 250GB/500GB.
Will do. And Thanks Again
