Re: [Dri-devel] Radeon PCI API

Your best bet, if you can find one, is a fireGL 8800.  It's basically
an overclocked 8500.  barring that the 8500's and 9100's are the next
fastest.

I'll have to check the docs when I get home.  The original PCI GART
work does done for HP for radeon support on Alpha.  At the time it was
just for regular radeons.  Michel did some re-arranging fairly recently
to unify the gart code between PCI and AGP.


 
 Also I am wondering if there is any word on specs for r250 and r300.
 If
 not, I would like to know what the best supported card is in DRI with
 the least software implemented GL.
 
 

I assume you are talking about r350.  the r250 is just a variation of
the r200 core and docs are available for that.  no 3D databooks are
available yet for r300 to my understanding.  I don't know if that will
change in the future or not.  I'd say the best supported cards are r200
based radeons (8500 to 9200 cards).

Arguably the Radeon 9100.

Just make sure you don't get some crappy card with a 64-bit memory 
interface; it'll perform like crap no matter how good the drivers are.

Well, I got a cheap 9100. It doesn't perform as good as my previous
geforce Ti4200, and they managed to cripple it by having an analogue
only DVI connector. But hey, it used open source drivers!

The 9100 only exist in versions with 128bit memory interface, or is it
dependent on manufacturer?

 well thats just great, I was hopeing to see something different other
 than r200 as I have had nothing but trouble and poor performance with
 them with DRI. I have yet to determine why but since AGP ppl have really
 good performance even in 1x, its looking like somethings happening with
 the PCI side, or mesa is using software rendering for PCI for some
 reason where it doesn't on the AGP.

You can check the Mesa and 3D driver debugging output for fallbacks
yourself, but both behave exactly the same regardless of the bus type.

As you may have gathered from reading this list, it's basically a
mystery.


PS: Does anyone have an idea why Chris's posts seem to get through to
the list directly, but also appear in the administrative queue?
