Yes, the specs.
Specs and Capabilities
Find out what doo-hickeys and thingamagidgets make the GameCube work. Here is a full listing of the Nintendo GameCube specs.
What are the technical specs for the Nintendo GameCube?
After Spaceworld 2000, Nintendo finally released official specs for the GameCube system. Although certain details have yet to be listed, what follows is a pretty complete list of what the NGC is made up of.
For now, enjoy these specs in lovely colored tables. OK, so maybe the colors aren't so lovely -but remember we are covering Nintendo, a company responsible for some pretty motley video game worlds. Thanks to the new design, you no longer have to suffer through the former "fruit-fest" that the old Planet's Tables had! Enjoy!

Thanks for the info but this is all Mumbo Jumbo to me & I don't mean Banjo's witch doctor friend! What do all of these Specs actually mean?
Glad you asked. Planet staff writer David Trammell has compiled an excellent descriptive section of the FAQ explaining each aspect of the Nintendo GameCube technical specs. Check it out for a better understanding of what the NGC can do.
A word on polygon performance...
I haven't mentioned polygon performance specs because it is such a gray area. Sony originally released raw polygon data for the PS2. Their numbers: 66 million polygons a second. Microsoft, not to be out done, quickly announced 300 million polygons a second raw (later trimming them to 125 million). Nintendo, on the other hand, only released real world figures that included all effects; or so the buzz goes. This figure of 6-12 million polygons per second is not the maximum that the GameCube can achieve in games; it is what the Space World technical demos were running at.
Hiroshi Imanishi cleared this up indirectly when answering a question during this interview.
Question: Nintendo insists there were no real games shown at Spaceworld though, despite the demonstrations?
Imanishi-san: True, and I think many people find that strange. However, the purpose of Spaceworld is to show off finished products. We thought it wouldn't be wise to show off the system and it's real capabilities almost a year before its release.
Nintendo deliberately low-balled the performance at the Space World show. Every viable source close to GameCube development kits confirms that the hardware can actually push closer to 20 million or more polygons a second with all effects on. There have been even been unconfirmed rumours of games being able to reach up to 40 million polys.
Realistically, first-gen PS2 games aren't doing much better than the Dreamcast with about 3-5 million polygons a second. The PS2, through the blood, sweat and tears of hard working developers should eventually push something like 10-15 million polygons a second... however, if they rendered 4 textures per triangle, you can cut that number right back down to 3-5 million polygons a second. There is no way around it. The GameCube is much more powerful than the PS2. Meanwhile, the Xbox should push a similar, or slightly greater number of polygons than the GameCube, but with only 4 textures. Increasing the textures layers to eight will cut them down to roughly 50% of the GameCube's polygon performance. Thus, most Xbox games won't use more than 4 texture layers. This will give its games less graphical punch than GameCube games. Many will find this very hard to believe right now, but all will be confirmed at E3. Ultimately, the Xbox and GameCube should achieve relatively similar graphics, while the PS2 will be lagging behind. We will have more concrete information after E3 in May.
