Is Voodoo4500 as fast as Voodoo5500 in an Amiga?

[Brian]

I currently have a Voodoo3000 installed in a mediator setup and have a Voodoo5500 that I'm thinking of adding to the machine, unfortunatly the latter card is Big and might interfear with even a smaller lowprofile halflenght zorro card behind it. As the Voodoo4500 have the same size as the Voodoo3000 it made me start to think.

The Voodoo4500, which came on the market after the Voodoo5500, have the same type of GPU/Memory (and speed of these) as the Voodoo5500 at 166mhz. And since the Amiga driver only allow for one for the GPUs and half the memory of the Voodoo5500 card to be used I wonder if the Voodoo4500 have the same performance as the Voodoo5500 when used in a Mediator equipped classic Amiga?

I'm with you on the likely and 99.9% sure bit, but I wish for an answerr that can confirm this.

While on the subject... what issues is there when using a Voodoo4/5 compared to using a Voodoo3. Hardware wise the newer GPU (VSA-100) on the Voodoo4/5 is backwards compatible with Voodoo3 GPU hence the Voodoo3 drivers work with these cards also but I've heard things like some screenmodes are missing with the Voodoo4/5 and other stories and wonder if someone can confirm these compability issues and perhaps come with a few workarounds for any that might exist?

The Voodoo4500 can be overclocked from 166Mhz to 220Mhz (though it start to bugg out at 190Mhz) using software on the PC. Anyone know if this overclocking is stored in the card and can be used on the Amiga, or if it's just driver based if theres something else that can be done to overclock the card?

Have anyone tried a AGP2PCI converter with Voodoo3500? and if so does it work (and how well does it compare to the Voodoo4500)?

This might be the approach to take to get the most out of the system both compatibility wise and speed wise. A true Voodoo3 card so driver work propperly and faster memory and core speed of the Voodoo3 GPU (Perhaps taking it all the way and scout for a Falcon Northwest Voodoo3500 Special Edition card running at 200Mhz instead of 183Mhz).
