After long time with my
A1X1000 with no hwaccel ( Radeon HD7970, Tahiti, SouthernIslands) I bougt Radeon
HD6670 (Turks, NorthernIslands).
This is one of fastest 1U cards with HWaccel for linux. Not so powerfull like Xeno's HD6970, but far better then my HD7970 with no accel.
Just now my config:
slot1 (PCI-e x8): 2U HD7970 - for AmigaOS
slot2 (PCI-e x8): 1U HD6670 - for linux
It works fine, on A1X1000 out of the box, no special xorg.conf is needed. I had to only revert changes made for southern island card.
HW acclelration works on all distros which I just now used (MintPPC-old, Debian8, Fedora+OpenSuse( thanks Xeno!), Fienix (thanks Casey Cullen!), glxgears varies from 1185 fps (Debian8) to 1436 fps (Fedora). Veru nice!!!
For comparison I equipped my
Powermac G5 Quad with older card:
slot1 (PCI-e x16): 1U X1900 G5 edition - for MorphOS, Mac OSX
slot3 (PCI-e x8): 1U HD6570 - for linux
It also works fine, but needs custom made xorg.conf, becouse X-windows does't recognize second card bus id correctly, and tries to work on X1900 ( which is doesn't work, as it is G5 edition. X1900 win flashed versions probably works).
But performance under linux is very nice - 3710 fps.
