Does any NV GPU with CUDA capability (8000 and higher I assume) exists on AGP bus ?

I've looked for AGP Cuda GPU's before and haven't found any, but there are PCI Cuda GPU's,

I just looked at two stores, and the only AGP Nvidia cards they have are 6200 or FX5200's,

PNY does a PCI 512Mb 8400 GS: PNY 8400GS 512MB GDDR2 DVI VGA Out PCI Graphics Card

I searched the web and it look like the 7800GS was the last/highest AGP slot grafic card.

CUDA only possible 8xxx series and higher. So min PCI slot.


What you would like to do? ;-)

Thanks! Yes, max I found was 7600 for AFP slot.
Will check PCI now :)

I need new GPU for one of old PCs, only AGP slot there (PCI presents too ofcourse, but I thought initially that AGP would have better chances as dedicated graphics bus...). And of course I want to buy GPU that will do SETI as well as show pictures ;)

What about PNY Quadro 4 NVS 280 ?

Quadro NVS 295 listed as CC 1.1, but 280 missed from list...

I would have thought nVidia would know their own product range - all the reviews I've been able to locate list the NVS 280 as having 64 MB VRAM, which is probably a show-stopper for CUDA.

I got a AGP HD4650 in the end, it does collatz no problem, Hybrid Astropulse slowly, i had hoped to get OpenCL working on it, but eithier Catalyst AGP Hotfix drivers don't enable OpenCL support, or CPU needs to be SSE2 :-(

My PIII still needs a replacement to FX5600, fan doesn't rotate without a helping hand, might get that PCI 8400 GS for it,

I tried for along time to get the NV 9500GT for the PCI (not PCIE) expansion slots on my dual Prestonia Xeon. The AGP slot is occupied by an HD3850 which, with the 11.3 APP Hotfix should continue to crunch here.

Anyone know where there are PCI 8400 GS for sale in the UK? I would like to purchase 2 for PrimeGrid.

A search turned up play.com - that link seems to be a genuine PCI offer, not the usual confusion with PCI-e.

Linked to 8400 GS in 2nd post of this thread, and it's cheaper than play.com ;-)

@Claggy

Thanks for the link, and it looks like I can do CUDA crunching. The GPUs are 1.1 CUDA rated, no different to the 2xNV 9500GTs I have in my dual P3.

I see they have either a quarter or half the number of shaders than the 9500GT has, but it should work.

I will approach this cautiously ...

First I will purchase one and see whether it can crunch both Collatz and PrimeGrid. This will give me comparisons with the same projects on the 9500GTs.

If they work OK, then I will purchase 3 more and make use of all the PCI and PCI-X slots. But, keep an eye out on the demand on the 450W PSU.

I need to upgrade the 800W PSU in one of my quads, which will allow me to sway put the 650W PSU in the other quad. This will then release a 650W PSU for the Dual Xeon with the multiplicity of NV 8400GS GPUs.
It's good to be back amongst friends and colleagues

With CUDA, Memory Controller isn't very heavy used, (far) less, when playing a game (1650 x 1280 x32 BIT), so PCI will work, if the card allows it bus traffic can be a bottle neck, running 2 at a time.
Strickly off topic
(Who remebers, or has used VESA-Local-Bus an ISA+ extension, with a video card
even longer then todays cards, the CPU was a DX 486 100 and it had SCSI HDDs and
CD-RW and a floppy drive, 2 a 5.25 (1.2MB) and a 3.5(1.44 and 2.88 MB)
Back On TOPIC...

Well I like my X9650 and i7 by far. (Still have two, a TULIP(failliet) and COMPAQ
both PII @ 300 and 350MHz. With a staggering 4 MB RAM(Slow as a snail),
Tried to install(1 day exactly) WIN XP x86 and BOOTing took 7 minutes!

I agree. The average memory controller usage isn't so much, but it can peak much higher.

I've been running "Open Hardware Monitor" program for a few weeks now. It shows my 460's highest memory controller usage peaked at 92%. Watching the current value as it updates I would guess ~35% to be average.

1 monitor attached, 1 GB and 1 wu at a time.

Looks like it could be HD4650 being capable of doing OpenCL instead.

This might interest some. A PCI 9500GT from Jaton video cards, sure beats an 8400 :-)

Sparkle video cards also had one available but I can't find a link.

I sure would like to get several, but several months of quietly looking have come up empty (hence the interest in the UK stocked 8400GS cards).

Sparkle did do PCI 9500GTs, indeed I am running 2 in my dual P3 server. But, I think they have now ceased, as seen here, leaving the 8400GS almost alone now.

......

I found the 8400 was barely worthwhile, they take the same time to crunch a unit as a "Core 2" CPU does (around 1:30 to 2:00 hours).

Maybe you could smile sweetly at someone in the U.S. to get the 9500GT's from Newegg for you.
