Thats a great speed that most amiga systems dont reach.
I get results of 2 voodoo3 systems they transfer only 8 MB/sec to GFX card.
I think the A1200 bus is 16 bit, but clock is 2*faster as Z2 that do only 4 MB/sec.
Z3 cards do 13 mb/sec i have Piccolo3 merlin.cybervisionPPC do 17 MB
I currently have done a SDL with hardware 3d support, game that support it you can download here.

On my cybervision PPC i work ok, but it work too slow on Voodoo cards.maybe somebody know more what can do to avoide the texture limit of 256*256 of voodoo Cards
3D hardware operation statistics
--------------------------------
Rasterization compatibility check failed due to the
following reasons:
2532: texture too large for perspective texture mapping
Rasterization statistics
Number of points drawn using 3D hardware: 0
Number of lines drawn using 3D hardware: 0
Number of triangles drawn using 3D hardware: 0
Number of quads drawn using 3D hardware: 393
But to make out of a amiga a good hardware that is no shame, USB2 cards are excelent when they have a directx10 chip.
Same as Cuda
http://www.nvidia.com/object/cuda_home.htmlIf there are some USB2 cards that support pixelshader and are full programable i plan to enhance the codegenerator that it can generate ATI Pixelsahader code from amiblitz syntax (only ATI seem release docs to build driver or write pixelshader)
It is not more work as i do 2001, when i add codegenerator support for 68k fpu.
also there is no need to support full datatypes as byte word.only long and float is enough.
on winuae can pixelshader programs currently written,so it can use on winuae too.
this gfx cards have RAM from 512 MB upto 1 GB Ram and have more more ram also compare with amiga ng Systems.
So a classic amiga can get a real rocket with less money, no CPU can get the power a cheap radeon 42000 GFX chip can get, because the memory Interface of GFX Card is much faster than on PC hardware.

because s3tc support on hardware is a lossy compression, this adapters or cards use the pixelshaders to decompress data.
maybe there is a USB to PCIe adapter somewhere out, and a cheap directx 10card can add
