Benchmarks Phoronix, known for their various speed tests and reviews, compared the latest in Ubuntu and what, until recently, used to be the lastest in Mac OS X with 29 different benchmarking tests. Some of the results were rather interesting.

Having a kernel that forces people to provide open source drivers. Whilst linus tolerates closed source drivers, its a risk creating them. And companies aren't going to pour all their optimisations into open drivers which any other company can just steal the optimisations. Otherwise its like handing over money to the competition.

Assumes that only companies can write optimised software. Not a valid assumption at all. The one and only advantage that companies have in writing software is that companies have access to secret information held by ... companies.


OK, so ATI have been good enough to release documentation recently, and even some code and a programming guide.

Expect the decent, open-source, 3D drvier for ATI chips to follow within a month or so.

Clearly not ready yet, but definitely on its way. Enjoy (when ready).

So ATI have released documentation (specifications) of their chips to open source programmers, open source programmers are busily writing an open-source driver for Linux for ATI chips, so that ATI chips will soon become the most powerful graphics chips available with a decent (non-binary-blob) 3D driver for Linux, which will no doubt be supported directly within the kernel, and hence Linux buying public will tend to buy ATI chips.

This is giving money away ... how exactly?

Sure. A month or so. Just wait, it's right around the corner.

Take a look at the sheer AMOUNT of documentation released, and the complexity of such a graphics processor.

Now try to tell me that the open source community can write as good a driver as ATI's for Windows in 1 month's time.

Intel had open specs and open drivers for far longer than ATI, the chip is simpler AND they actually have paid developers for the xorg driver. The intel driver is probably the best maintained driver for xorg right now.

The result?

The benchmark here clearly shows that the result is not what you would expect, the performance is awful. Comparing my hp box at work, the graphics performance are actually better in vista than linux with the xorg-intel driver, even after tuning the driver parameter for migration heuristics (which did a HUGE difference).

Compare this to the nvidia binary blob, which gives me the opposite result on another box. ATI is in an unusable state at the moment (I'm not taking sides with any graphic vendor, that's just a fact).
