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

Any AGP expansion bus for any card at all?

The Elbox Dragon 1200 has an AGP port and exists. Unfortunately it was only ever demoed and never made it onto sale. Likely due to problems with compatibility and performance of 68k software on the Coldfire.

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. The Amiga is too old and AGP is not supported. The closest is the "PCI" video slot on the Phase 5 accelerators for CyberVision video card. For less cost and more availability, plus extra coolness, a Mediator board with VooDoo 3 3000 or Radeon 92x0 is fast and pretty, adding support for other PCI options USB, NIC, Sound cards etc

AGP is quite close to PCI from the system software side it's actually the same asfair. nyway the point is to use the card, not the bandwidth.

It's the same idea behind 8-bit MCU:s that have Ethernet connection at 10 or 100 Mbit/s.

You can get PCI versions of most any AGP card, though. I've even gotten PCI versions of PCI express graphics cards.

But how many work with the Amiga?

Default Completely off topic
The "PCI" slot for the CyberVision has direct access to the CPU and RAM, making it potentially very fast for things like RAM cards, SATA cards and the like; it is not limited to 2/4 GB as is the Amiga side

That's a good question, but that's a software issue, not a hardware one. An AGP slot would just add a whole new slew of cards that aren't supported, and allow supported cards to be accessed faster than the CPU actually can manage...

With AGP cards becoming more and more difficult to source (at least new ones in the wholesale chain,) it'd be a waste of time trying to develop. The next useful expansion would be PCIe (PCI Express.)

Unlikely as Elbox won't even support their current hardware.

@LoadWB, You'r right but I were curious if such expansion ever was made in larger quantities.

PCI-e is proberbly the next target. But I suspect FPGA Amigas will be the thing when the real hardware will "die".

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
