I am appaled with my GeForceFX 5200 performance!!!
 
Hello !

I have wanted to share with you my discontent. I have bought a GeForceFX 5200 card whose fillrate performance doesn't match my old
Creative Annihilator's (GeForce256 DDR) performance. I am working on an
intensive fillrate application and it runs at 180 fps on my old card and at 160 fps on the new 5200 card. I was astonished. I also have found a program that stresses fillrate on nvidia's site and my fillrate performance was about a third of a geforce 3 card.

The conclusion:

GeForceFX 5200 SUCKS !!!

It has the functionality I need, and its core is pretty strong, but memory is its gretest disadvantage.

Do you have FX5200 with a 64 bit memory bus, or is it a proper one (128 bit)? If it's a FX5200 with 128 bit memory bus, it should be a lot faster, so you probably need a driver / Windows reinstall. If it's the infamous 64bit-version, then there's nothing that can be done with it.

It has an 128 bit wide bus.

It was madeby Asus (model V9520)

Hmm... The V9520 cards actually sold to customers seem to have somewhat worse memory clocks than advertised. It comes with 331 MHz DDR, when the advertisements claim 400 MHz DDR.

Furthermore, all 128 MB Asus V9520 do not necessarily have 128 bit bus. The normal 128 MB V9520 cards with 8 memory chips on board have 128 bit bus, whereas there is supposed to exist a variant with 4 memory chips (see link), which has a 64 bit memory bus. Add to this the slower-than-advertised memory clocks, which lead to a ridiculous bandwith of 2.7 GB/s, about one tenth of the today's top cards. Selling these cards would be an outright fraud IMHO. :mad:

Yes, my card has a 331 MHz memory clock, but has 8 memory chips.
Also, I have no idea why they sell it at 331 MHz, because mine is working at 406 Mhz (but it think standard memory frequency is 460)

That's easy. The memory chips used in the card are rated by the memory manufacturer to run at most 333 MHz DDR. If they would be run at 400 MHz DDR, it would be quite big overclock for the rams, and quite many of the cards would have overclocking artifacts right out of the box. This would cause a lot of RMAd cards, which they obviously don't want to happen.

Should I take the card and show it to my seller ?
It should be replaced since it does not meet the advertised standard...

I wouldn't bother, because the chips on your card actually can run the advertised speed with overclocking, if I understood you right. I think there is a problem with your setup, because it should be a lot faster than your GF256. Try first a driver cleaning / reinstall procedure, and if it doesn't help, check and fiddle with your computer's AGP settings in BIOS.

BTW, what 3dMark 2k1 scores are you getting?

fuxifuxi 11-01-03 09:16 AM

My card works most of the time at least 2-3 times faster than my GeForce256, but only when the limiting factor is the geometry. When the fillrate is stressed and geometry is poor, the differences are minimal (when I don't overclock)

That doesn't sound right, considering the theorical specs of both cards.
Could you try a benchmark to give us MPixels/s numbers for 1 texture and multitexture scenarios? Such benchmark exists for example in 3DMark2001 and 2003.

With a Pentium3 600Mhz it is limiting the performance you will get from that Video card. Your CPU is a bottleneck, and cannot process the information from the Video card fast enough.
