Discussion Overview

The discussion revolves around the compatibility of new graphics cards with existing PCI slots on motherboards, particularly focusing on the transition from PCI to PCI Express (PCIe) and AGP cards. Participants explore options for upgrading graphics capabilities in older systems, considering both theoretical and practical aspects of hardware compatibility.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • Some participants express concern about the availability of new graphics cards for PCI slots, suggesting that most modern cards are designed for PCIe.
  • One participant mentions that if only PCI is available, options are limited to older models like the Radeon 9250 or Geforce 5700LE, with performance considerations based on chipset compatibility.
  • There are suggestions to check specifications on retail websites for compatibility and to consider used cards if necessary.
  • Participants discuss the potential for AGP cards, with some noting that they can still perform adequately for certain games, depending on resolution and settings.
  • One participant highlights that AGP cards are phasing out, and a budget of $30 is unlikely to yield a suitable card for modern gaming.
  • Another participant shares anecdotal evidence of an AGP card performing well in lower resolutions, suggesting that performance can vary based on specific use cases.
  • There is mention of the bandwidth differences between AGP and PCIe, with some arguing that AGP still has utility for certain applications.
  • Participants question the rationale behind the industry's shift to PCIe, suggesting that AGP cards can still meet needs for less demanding applications.

Areas of Agreement / Disagreement

Participants generally agree that PCI slots are outdated for modern graphics cards, but there is disagreement on the viability and performance of AGP cards versus PCIe. The discussion remains unresolved regarding the best approach for upgrading older systems.

Contextual Notes

Some assumptions about chipset compatibility and performance benchmarks are mentioned but not fully explored. The discussion reflects varying levels of experience with hardware upgrades and the implications of budget constraints on choices.

I was thinking of buying a new graphics card, but I had a quick look in my computer earlier today, and I have some PCI slots on the motherboard, but all the new graphics cards use PCI express. Will there be a problem trying to install a new graphics card on the motherboard I already have?
 
Computer science news on Phys.org
Yes, there isn't much out there anymore for PCI. I'm actually not sure if anyone makes a decent new card for it. However, since your PC is probably pretty old anyway, you'd probably do alright finding a used PCI card somewhere. What do you have now?
 
If your left without having even an AGP slot and PCI is your only option, the best you're going to get will be either the Radeon 9250 or a Geforce 5700LE depending on your chipset, as Intel chipsets typically function better with Nvidia cards while the same holds true to AMDs with ATI's. To be honest though, I've never ran into any real problems mixmatching chipsets with different vid card manufacturers... other than with overall benchmark scores.

If you do get a PCI card, make sure you at least get one with a 128bit memory interface. Benchmark scores literally double going from 64 to 128 and considering this is PCI we're talking about, you may as well get as much as you can out of it. The standard PCI interface only pushes a max bandwidth of 133.33 MB/s where AGPs range from 266 to 2133 MB/s.
 
Just do your pre-lim shopping on a website like CDW or Tigerdirect and they will have the specs, compatibility, etc.
 
Are you adding a second card to your system or replacing the existing one (which will likely be in an AGP slot). Just go out shopping for an AGP card. They shouldn't be too hard to find. I just replaced my AGP Ti4600 with a 6200 card a few weeks ago.

A PCIe card won't fit into a PCI slot.

How do you think of the AGP Video Card? I also want to get one in order to enjoy some of the latest PC games on the market today, this one seems can support cutting edge graphics. And I searched the one for $30

It depends really. Who is the motherboard manufacturer and what's the model number?

That's not an AGP video card...

AGP cards are phasing out. PCI-E cards are the cards that people purchase.

If you want to do gaming that include the latest games today, an AGP card will not do. Also, a price budget of $30 will not do it either. You will need to spend at least $100 on a decent graphics card to play games like Call of Duty 4, TF2, etc.
 
AGP cards are on their way out, but still really aren't that bad. Not even a year ago I put an AGP 512MB PNY 7600GS in a friends old 2.8GHz P4 computer. It could play Doom3 at 1024x768 with FSAA and AF cranked to the gills. I also transplanted that same card into another like computer and that owner has been playing BF2 and 2142 on it for a whiel now with no hiccups. people still underestimate how much 2.1GB/sec worth of bandwidth really is. The newer 16X PCI-E slots can move data both ways at around 8GB/sec (4GB/sec oneway) and is GREATLY larger than the amount of data that current (and near future) video cards can push. It does offer some nice scalability but but it's still overkill for most of the games out there. Even the 8800GTXs don't come anywhere close to filling that amount of bandwidth.

Now, here's the key. If you don't plan on running high resolutions, you can get by with an AGP card no problem. If you're wanting to run your games on a 30" widescreen monitor with the resolution cranked to the gills and all the visual features maxed out... an AGP card won't cut it. There's actually a few benchmarks that I've seen where at lower resolutions an AGP card was able to outperform my big-gun 768MB 16x PCI-E 8800GTX.

Interesting - do you know where you saw it?

I'll have to look through my links at home but i'll try to find them. It was on quite a few different sites if i remember correctly. It comes down to how the manufacturers are building the cards to handle the extra eye candy at the high resolutions. Unless your really pushing the card (high-end cards), they don't perform to their potential. You can actually get higher framerates with older, less expensive cards depending on the situation. The deal with AGP vs. PCI-E is that neither is close to being saturated... it's just that the manufacturers have dropped AGP and moved on to making PCI-E x16 bus cards because that's where the industry is going. IMO, it's a little silly that they came out with PCI-E. The only real benefit is Crossfire or SLI capability.

Do a Google search for "AGP vs PCI-E". You'll be surprised what you find. This links is a little old but other than the new 8XXX series cards, it still holds true.
