was just reading information about i850e and i845g/e chipsets and their lack of agp 8x. i'm thinking ahead to my inevitable upgrade to NV30 and wondering how much of a performance hit i'll be taking with AGP 4x.

From what I've read it seems that the performance gain of AGP 8x isn't nearly as big as the increas from 2x to 4x was. In fact I think that the difference between 4x and 8x is rather small. I'm willing to bet that NV30 and R300 will run just fine on 4x.Quote:

The performance difference between 2x and 4x is rather small as well in terms of real world numbers.
It won't be a very vast improvement. I wouldn't be worried to have an 8x AGP motherboard.
AGP 4x isn't even fully used yet, not even with current games. By the time you will need AGP 8x it will be time to upgrade your video card again.
Interesting. I just took for granted that video cards were pushing the limits of AGP 4x, hence the move to AGP 8x in the next generation of cards. I did assume that having an AGP 8x mobo would not be of much benefit at first because the first few generations of AGP 8x video cards would not be able to take full advantage of it.
Anyway, as you can see, I'm no expert. I'd appreciate further explination. Educate me!

correct
Gotta love these forums ;). Yeah, if you try to run in 2x in something like 3dmark, the hit is only a couple hundered points, nothing too major. But with the numbers that thing will be pulling, 200 3dmarks will be worthless. :) Don't worry about it. You could always use it as an excuse to get a new mobo though.....
**** I still run my 8500 in 2x mode for pure stability because the gain in 4x is worthless. It averaged something like 100 points in SE.
The reason you see little or no gain is this. AGP 4x is is only capable of moving 1.06GB/sec of data. This will basically double with AGP 8x to 2GB/sec. This is where the problem lies. Most video cards already have well in excess of this, pushing 6-10GB/sec for the average to high-end cards. Why in the world would you want to retrieve textures out of memory at 2GB/sec when your video card already has 3-5x that much bandwidth?Quote:

Heh, im running 1xAGP cause this old board is too unstable with the GF2 ti at 2x. the difference between 2x and 1x for me is around 150 marks. My best ever score was at 2x AGP but its not reliable.
Whoops, nevermind.
itsnt this kinda like the way cards now have 128mb memory and i thought that i read here or somewhere that games are just now using 64 fully.
