computer for the weekend but I'm not sure how to go about it. I bought
the laptop a month ago and AW made a lot of screwups, shipping, tech
support, customer support, you name it...--long story.
Anyway, they're letting me hang on to the laptop and test it to see if
I still want to hold on to it. But I'm not sure how to test it. I
downloaded POV ray and rendered an image called skyvase.pov.
* The Alienware with a 2.0GHz Core 2 Duo, a gig of ram took 36 seconds
to render an image at 1280x1024, anti-aliased 0.3.
* My old Compaq Presario laptop with a 2.8GHz Pentium 4 CPU and a
768mb or ram took 44 seconds to render the same image.
Please keep in mind that I don't understand chip speeds specifics that
well, I only read the numbers and the advertising. I expected
dramatically better performance from the Alienware--maybe I was just
unrealistic, or maybe I'm not testing them correctly.
The Alienware Area-51 m5550 specs are 2.0GHz Core 2 Duo, a gig or ram,
72rpm hd and a dedicated 256mb NVidia 6600 with a 17" WUXGA.
The COMPAQ presario is 2.8GHz P4 CPU, 1 gig of ram that it shares with
video, a slower hard drive and a 15.4" screen.
Obviously the dedicated graphics and faster hard drive makes a huge
performance difference. But that much? I just expected much better
performance from the c2d chip for all the advertising that Intel's been
Re: alienware testing.
Well, not necessarily. Integrated graphics and a slow hard drive
wouldn't make any difference for ray tracing.

Did you run povRay with two threads, or does it do that automatically?
If that was single threaded rendering, I would call that an decent
victory for your new computer, and try it again for with two threads for
much better results.
