How many bits are the modern consoles these days?

[RP2A03]

By the way, there are 128-bit processors in home game consoles, but they usually aren't the main processor. The Dreamcast has a 128-bit graphics card in it, although it's main processor is only 64-bit.

The Emotion Engine of the PS2 is also a 128-bit processor.

The GameCube is debateable, as the internal processor has weird limits on the data that can be passed back and forth (much like the Jaguar), but it is also essentially a 128-bit processor.

To call any of these systems 128-bit sounds quite ridiculous to me. From what I understand, the only thing 128-bit about these consoles are the vector registers, where vectors are stored, but no actual math takes place. And for what it's worth, the N64 also has 128-bit vector registers...
