What happened to AGP?

AGP used to be a big thing. It was cool too. You could power the GPU of your choice and with each year that AGP got faster you could still use your old cards! PCI GPU's were not the most popular and a few computers had PCI graphics slots, but AGP was super popular most of the time.

AGP or Accelerated Graphics Port, has been phased out by pci-express arround mid 2008.

PCIe came out and was quite a bit faster. If I'm not mistaken PCIe was actually designed to supersede PCI, PCI-X, and AGP all at the same time.

PCIe 1.0 = 4 GB/s
AGP 3.0 = 2.133 GB/s

Uhh.. No? AGP had 2 or 3 versions, and they were not backwards compatible, not only the cards didn't work if you put them in an older slot, they fried up.

I dunno. I've been able to use a Riva TNT2 and an ATi 9800 Pro both on the same board.

Manufacturers made them compatible with voltage supply settings in AGP 3.0 capable boards. But yes, if you stuck an AGP 3.0 card in a 2.0 slot you would end up with a dead board and GPU.

Weren't there different size slots for different versions ?
Been along time since I use AGP. Geforce 2 and A Geforce 4.

I actually have an IBM NetVista I am working on that has a teeny AGP slot, I think.

I have 0 clue wtf it is actually but it has an integrated chip. Wierd for a Pentium 2 Machine too.

I Know with some of the small weid AGP slots were to expand the memory.
From memory?

:P I dunno if that's a thing. Awesome if it is though.

The standard AGP slots, no just the keying for them, some motherboards had keyless AGP slots, then there were the proprietary AGP standards made by a few of the motherboard manufacturers for server equipment.
