AGP bus expansion for Amiga?

[utri007]

Individual computers has also made Zorro to PCI bridge.

X-Surf cad has a PCI card to connected Zorro to PCI brige. Would be nice to know would it be possible to use it with other PCI cards

 That is not a "bridge" any more so then the Domino Graphics card has a bridge; it is a specialty slot meant to handle one specific card.  Any other PC type cards won't work (and they were tried in both cards).  One needs specific complex logic as in the Mediator.  Ergo, it is possible, but as noted before, AGP is too fast for a Classic Amiga to really keep up, the PCI standard handles more than just video (in the case of OS 4.1, the developers not only wrote their own code for the supported cards, but wrote code to support the ESS-1 Solo sond card and the sii3112/4ide SATA cards).  Elbox does not support these two

X-Surf uses an ISA bus card, not a PCI card. Big difference.

[danbeaver]

Yes but 10Mbps is still 10Mbps despite the slot type: ISA, PCI, ZORRO II, or USB.

The X-Surf NIC is ISA not PCI

Do there exist any expansion for Amiga that makes it possible to make use of graphics cards with AGP bus connection ..?

No but the UltimatePPC card that is  in development for the A3000 A4000 will have a lot of integrated peripherals onboard, graphics, sound, ethernet, USB etc,  all of which should easily outperform any PCI or AGP cards running across the Zorro bus.

:eek: Holy cow.  Hadn't seen this before.

Not needed since AGP bus is just gfx card.
Pegasos PPC boards use it.

[danbeaver]

The proof will be in the pudding (and supporting software drivers) for the UltimatePPC

There are some special cards that (ab)use the AGP bus for other applications than graphics.

Pegasos PPC boards use it.

There's some comments that the AGP isn't real or useless AGP 1x.

There is no "real" AGP bus on Pegasos 2 but it has AGP connector so you can use AGP cards on it. While it is just AGP 1x bus it is faster and more reliable than AGP 2x bus in Pegasos 1 or AmigaOne.

Efika has similar AGP implementation since there is no real AGP bus either but you can user either PCI or AGP cards on it.

Fuctionally you can stick and AGP card that will work slower.
However, AGP bus is complete history, like ISA.

[danbeaver]

I'm afraid the Amiga is considered to be "complete history."

[Duce]

Outside of the SAM boards, there's no point in even having AGP, because there's no way an Amiga CPU would even come close to using AGP levels of bandwidth.

No AGP on my SAM or on any other one I've ever owned, used or seen.

Actually, I meant that the SAM boards are the only ones with enough processor horsepower to potentially benefit from AGP, not that they had it. (And even that's a definite "maybe.")

[freqmax]

If the market place mainly provide expansion cards using AGP. That's what goes into a design. Same with PCI, there's many embedded designs that have no use for even a small part of the capabilities found in PCI, but the marketplace dictate PCI as the common denominator. PCI-express is the interface of choice right now but it's a pain in regard to timing and RF design of circuit boards so I hope PCI card remain abundant.
USB has in essence replaced ISA (both are crap!)
