Wii vs. GameCube Hardware: More Than Motion Controls

The statement is partially true but oversimplified.

Shared Core

• CPU: IBM "Gekko" (PowerPC 750CL) @ 486 MHz (Wii) vs. 485 MHz (GC) — negligible.
• GPU: ATI "Hollywood" (Wii) vs. "Flipper" (GC) — same architecture, Wii clocked 243 MHz vs. 162 MHz.
• RAM: 88 MB total (24 MB 1T-SRAM + 64 MB GDDR3) — identical.

Key Upgrades

• Motion control: Wii Remote + IR sensor bar (fundamental UX shift).
• Disc drive: Wii reads 12 cm DVD (4.7/8.5 GB); GC reads 8 cm mini-DVD (1.4 GB).
• Storage: Wii adds 512 MB NAND + SD slot; GC needs memory cards.
• Network: Wii has built-in Wi-Fi + Ethernet (via USB); GC needs broadband/modem adapter.
• Video out: Wii adds 480p component (progressive) standard; GC needs rare component cable.

Wii is a direct architectural successor — same DNA, meaningful I/O and storage upgrades, not just a waggle stick.
