Xbox was more powerful. CPU wise, they had parity, while the Pentium III on the Xbox was clocked higher, IPC on Gamecube's processor was higher and architectural differences made it have better real world performance, therefore the lower clockspeed didn't mattered. GPU wise, Xbox was more powerful, even though GC actually had the game that most pushed polygon counts on that gen(20 million for Rogue Squadron 3). Since Xbox GPU supported pixel shader and vertex shader, though, games generally looked better on Xbox thanks to that, even though it was the main reason that made the GPU underperform on the polygon count department since pixel and vertex shader operations took a lot of the GPU's processing power.
