Recommendations? PCI 1x vs. PCI

Greetings,

I would like to upgrade video in a Dell OptiPlex GX520 (specs at http://support.dell.com/support/edocs/systems/opgx520/en/ug/mtspecs0.htm#wp1133451)

What are the advantages of PCI 1x over PCI? I am looking at these two cards:

EVGA 256-P1-N399-LX GeForce 6200 256MB 64-bit GDDR2 PCI Video Card
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

HIS Hightech H155HMF256EL1N-R Radeon X1550 256MB 64-bit GDDR2 PCI Express x1 Low Profile Video Card
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

The only differences are:

ATI vs. Nvidia.
I prefer Nvidia because they support Linux, I can work with generic ATI drivers if I have to. This card will go into a dual-boot system - Ubuntu/Windows XP Home. The reason for upgrading is primarily to play World of Warcraft and Everquest (the only reason why Windows is on this machine) at reasonable speeds which has not been possible with the on-board Intel graphics.

The Nvidia PCI card has a Core clock of 300MHz, ATI's PCI 1x card is 550MHz.

The Nvidia PCI card has a Memory Clock of 533MHz , ATI's PCI 1x card is 800MHz.

Price - Nvidia PCI card is $45.99 and the ATI PCI 1x is $99.99.

Max resolution for both cards is much higher than anything that will be needed.

So how much does Core clock and Memory clock speeds impact video performance? Is there a clear advantage in using PCI 1x over PCI?

I appreciate your comments!

If you're playing games the Ati card is the way to go.

Linux support is spartan but really if the reason you're buying is games, the X1550 is exponentially better from both a far better GPU to a noticably better interface.

And really, Linux support will probably improve over time (either minimally or significantly who knows), whereas the GF6200 will always be weak with no improvement.

I think PCIe x1 has about twice the bandwidth of PCI, but at the low end, bandwidth isn't super important.

the ATI card is better than the nVidia

I put that money toward a new mobo, if thats a standard AXT or micro ATX case

What about using a PCI 16x card in the 1x slot? I am going to go pull the case cover off and see if there's enough clearance on the motherboard for that.

It's the $99.99 price tag . . . . if I can get similar performance with a less expensive card that would be my preference.

Ah if it were just a matter of the motherboard only . . . . with that purchase I'd end up having to buy a video card as well. Can't see the advantage there but thanks for the reply just the same.

x1550 for 99$ ?
ISn't it a bit too pricey?


I've been online shopping for 3 hours . . . . do you see it anywhere else for less? That would be sweet!

newer OBG will outdo those overpriced and hobbled cards

There's of clearance for a PCI 16x card, and the price is right too.

I'm looking at http://www.newegg.com/Product/Product.aspx?Item=N82E168... for $34.99

Sorry groo but what is OBG?

(Got it right when I hit submit (on board graphics).)

In my experience and in my opinion - I have never had good luck with Intel's on-board graphics and ANY 3D app. Add to that the fact that they do not support OpenGL (which is on of the backbones for KDE), I am not likely to ever use it as a permanent solution unless those practices change in the future.

Besides, I'm just trying to get some life into an older computer, not rebuild the silly thing.

No you cannot just plug a PCIe 16X card into a 1X slot.

You would need an adapter like one of these;

Even then they are buggy and only work with some cards, and for the price, might as well buy a new MoBo.

And the bandwidth for PCIe 1X is effectively 4 times as much as PCI (and bi-directional), and the difference is pretty significant. It probably wouldn't matter as much for the GF6200 as the X1550, but it does make a difference.

Here's a quick easy representatio of the bandwidths involved;


Anything above a low end GF8600/HD2600 will be chocked by PCIe 1X, and PCI would turn it into something comparable to the 780G intergrated chipset.

Either get an updated mobo with a solid GF8200/9100 intergrated VPU (since you use Linux and thus intel or AMD IGP is little benefit) or else get the X1550.

This is the very best info yet, thank you so much for taking the time to give me this kind of information. It is very much appreciated!

Now if I could just get Christopherr to cough up some real links to those cheap boards he says are out there :-)
June 18, 2008 7:47:28 PM

Ok, so the motherboards with on-board Nvidia graphics are lots cheaper than I thought they'd be.

The next question is DDR2 667 backward compatible with DDR2 400/533 RAM? That's what I have and the cost will go up if I need to upgrade RAM as well.

Thanks again to you guys! You are the best ;-)
June 18, 2008 7:56:35 PM

If I get a motherboard with integrated video they are all DDR2 667 or DDR2 800, what I already have is DDR2 533.

So my question is if I purchase a new MB can I use the RAM I already have?
Is it backward compatible?
