Gamecube runs higher-res textures and can push more polygons than 3DS, even without counting the 3D mode which should cripple performance a lot on a 3DS. 3DS has the edge in the shader department and anti-aliasing usage seems to be less expensive than it was on GC(every Capcom game uses FSAA in 2D mode).
