AGP Performance: 8x vs. 4x

[noko]

AT lower resolutions where bandwidth limitations are not as much I expect AGP8x would show a better benchmark. At gaming resolutions and all the candy turned on it will probably not show much of any improvement. Still remember the cpu's of today and memory of today is a hell of alot faster then a couple of years ago, plus newer games are pushing over 4-8x the amount of polygons over the previous games. Meaning the cpu will be pumping those polygons to the graphics cards via the agp port at which agp4x at times will be limiting.

actually, awhile back, when video cards wasnt as advanced, yes, the CPU would be processing alot of those functions, and yes, the AGP speed would be a factor. but now, things have changed and now, its no longer being so CPU reliant, but yet, now alot of it is on the video card and its VPU ..... thats where the ram in the card will help (notice, its better to have a 128MB card instead of a 64MB card when Doom3 comes out, as itll have 80MB scenes in the game) ....

100 Character Limit Sucks!!

Vertex points are still being transferred to the video card but your right the T&L part of the card handles alot of traffic internally on the card vice using the CPU. Well a test of 4x and 8x maybe the only way to see if there is any significant advantage in doubling the bandwidth between cpu and video card.

i honestly dont think this 8x is such a big thing...even the Ti4600's werent pushing and pushing the boundries of the 4x .... not many games were programmed to take advantage of it ..

Crashman, I disagree.....The reasons that you posted that the AGP does little effect in increasing performance in previous cards, and does not take into effect the bottlenecks that were influencing the performance. In the past, it wasn't the AGP bus that was limiting the video card, it was memory speed and processor/bus speed. Now that video cards are doing much more of the computations on board,and video memory is so much faster, the AGP bus becomes much more important. I'm an AMD man, and am researching a viable Mobo + ATI 9700 pro combo as we speak, and 8X AGP is one of the things I'm looking at.
