I am considering a graphics upgrade that involves putting a PCIe 16x graphics card in a PCIe 1x slot using an adapter. How much GPU performance will I lose by doing this? Will the graphics still be significantly better than if I used integrated graphics? Will the connection be a bottleneck if the card is fast enough?

Thanks in advance

The bandwidth would basically be cut down to 1/16th of the 16x interface, but its definitely doable. Hard to say what kind of hit you'll get as far as performance without some benchmarks.

Here are a few charts showing some gaming stats (very old article btw, but still viable):

Here is the beginning of that article.. fun read :thumbup2:

I've read that video decoding should work well with this, but don't expect to get a lot of gaming power out of it using the 1x interface, as bandwidth provides a big roll in gaming. What exactly are you wanting to upgrade your video card for?

for anything other then perhaps some encoding and maybe blu-ray watching, it would definetly bottleneck-especially in gaming. Youd be better off just getting a video card that was built for the x1 interface natively, or upgrading the motherboard. Also make sure your power supply can handle the video card upgrade.

Hi,

The 1X Video card I use gives me 4.7 Desktop Aero and 5.8 business and gaming in WEI on a Core I3. This what I used http://www.newegg.com/Product/Product.aspx?Item=N82E16814500233

Ports

HDMI
1 x HDMI

D-SUB
1 x D-SUB

DVI
1 x DVI

NVIDIA Unified Architecture

NVIDIA PhysX Technology

NVIDIA CUDA Technology

NVIDIA PureVideo HD technology

HDMI xvYCC Color & DeepColor technologies

Dolby True HD & DTS-HD Master Audio bitstream support


The problem with using a 16x PCIe card is that it has to have clearance so the the card plugs in properly and that it does not hit anything on the motherboard. I had 16X cards but they wouldn't clear the motherboard.

Good Luck
Roger
