Hi all,

To make a test with a clear result is even more hard, when the two
competitors are close to each other like A64 and XEON. So the last
percentage depends on the choosen Test-Scene..

I remember that I sent a e-mail to Mr. Hauser who did the Test, telling him
about the problem to choose "Scene X" for a Test as well as a factors like
Resolution, total Rendering-time/Overhead.

As A64 and XEON are not far from each other, but have quite big diffrences
in Architecture, you can choose "Scene X" which renders better on CPU X.
Because the sort of calculations that are needed, are faster with the
current CPU-Architecture.

So the best choice would have been to take a scene which contains all sorts
of calculation (benchmark.pov) for single CPU-Testing. Alternatively it
would have been possible to render all Scnenes and give the results "by
feature" or "for all scenes" (A64 faster with Photons, XEON better with ...

However I think they did not want to get too special with this test, and
someone informed them wrong about optics.pov or they read it in a posting

Knowing that we can still say that both systems (A64 and XEON) are ok for
use with POV-Ray /SMPOV and there is not one of them which is far behind the

Happy new year for you all
