IF YOU OWN A X800XL AGP, I need a favor

[Dr Asik]

If you own that card or something performing similarly in AGP (7800GS, X850Pro) and can run it in AGP 8x and 4x, I'd would appreciate IMMENSLY if you could do some comparative benchmark between AGP 8x and 4x, preferently with some of the most demanding graphic programs, example 3dmark 05 or 06, Fear 1280*1024 high settings, Oblivion high settings, etc.

Thanks in advance.

I doubt you'll find anyone who will bother unless you give a few reasons for your interest.

AGP 4X = Choke.
/thread.

I have an X800PRO... *edit* AGP

But yeah 4X is obviously a lot slower.

no i remember there was barely any difference between 8x and 4x

 

[Sonikku]

That is correct. In a world where video cards were never starved for the bandwidth in the first place, the difference between 4x and 8x AGP is negligible.

 

[Dr Asik]

The reason why I'd like such benchmarks is that all comparative benchmarks between AGP 8x and 4x you can find on the net are pretty old (dating back to 2002-2004), and while they show approximatly no difference between the two modes, slightly larger gaps appear with more demanding applications; the biggest one I've seen it with Far Cry, with a 6% difference.

Since the gap seems to widen with newer applications that push the hardware to it's limits, I would like an update on the topic, especially since I'm getting that card and will not be able to run it faster than AGP4X. You would be producing the only such comparison on the net!

my 6800 shows negligible performance differences (1-2%) between 4x and 8x AGP in all the games ive tried (hl2, oblivion, americas army, splintercell chaos theory)

Ayah and Ragnarok2!!! Why did you speak if you did not really know the answer?

The answer is, you can run a 8X AGP card in a 4X only slot and suffer ZERO performance loss. The AGP 4X bus was never near being saturated when the marketing gimmick of 8X AGP came out. Get it OP? It was/is a gimmick. Your X800XL "8X" AGP will run at it's full potential on a 4X AGP slot mobo.

This is correct for the most part, the difference between 4x & 8x in an otherwise identical system is either zero or so close to it, it doesn't matter at all.

As I recall some of the first 8x cards performed a bit better then higher clocked 4x parts that came before them, notably the GeForce 4 Ti4800 8x which outperformed the higher clocked Ti4600 4x model, but AGP speed wasn't the reason for the difference, it was an improved memory controller on the newer cards along with other small improvements.

Thank you very much. I would like the numbers if possible but what you're basically saying is that even modern applications and gpus haven't still pushed AGP4X to its limits, which I was fearing. I couldn't be sure based on older tests, so thanks.

a card that uses more bandwidth (i.e. 7800gs or x850xtpe) might be able to saturate the 4x bandwidth but not slower cards like x800's and 6800's 🙂

QFT, newer cards should saturate 4x
