How Many Bits Is the Nintendo Wii? (It's Not That Simple)

The Wii isn't marketed by a single "bit" rating like 16-bit or 64-bit consoles of the past. Its architecture is more nuanced:

• CPU: Custom IBM PowerPC "Broadway" @ 729 MHz. Not strictly 32-bit or 64-bit; designed for efficiency over bit-width marketing.
• GPU: Custom ATI "Hollywood" GPU. Handles 3D rendering with fixed-function pipelines; not comparable to CPU bit-ratings.

Performance is better described by clock speeds, memory bandwidth (21.3 GB/s), and shader capabilities than by a single bit number. The "bit wars" ended long before the Wii launched.
