Original XBOX performance

The GC had decent FP from both CPU and GPU, most other only had decent from one. It could do closer to 11 GFLOPS.
It also had the most impressive matrix transformations, able to do 3 billion/sec. (PS2 and XBOX at 2 billion).

Overall, I would say the graphics on the GC were more impressive and the original, except for one thing... the biggest limitation with the gamecube in terms of graphics being more obvious was the media was only 1.5GB on the mini dvd and no internal hard drive, and Xbox could read 6.8GB on a dvd. That limited or extra storage played a factor for many games in the graphics quality...

The Mini Discs were probably not as big of a limiter as you might think, especially with good compression algorithms.
It did mean full motion video and high quality audio tended to get cut back first though.

The Gamecubes CPU is IBM PowerPC 750 derived.
A Celeron 733mhz is able to beat a PowerPC 750 chip operating at 500Mhz.
Add that the Original Xbox's CPU is a Coppermine based Celeron but with a 33% faster FSB and double the cache associativity... And the fact the Cubes' CPU is operating at 486mhz rather than 500Mhz... It's a no brainer that the Xbox's CPU has the edge... And the games show.

But the other bonus point that falls in the Xbox's favor is of course... Audio.
The Xbox leverages the impressive nVidia Soundstorm, which offloads a significant amount of CPU burden, roughly 4Gflop worth of capability alone on that front.
Not only that but it could do full 3D positional audio...
I kinda' wished nVidia kept up it's audio efforts or Aureal stuck around, they were pioneering some impressive Audio solutions, in some aspects we have gone backwards since those days.

The Xbox also had faster and more Ram, which helped significantly.
