Nintendo has thus far revealed little about the Wii's specifications, but unofficial information has trickled out that paints a pretty complete picture of the upcoming console's innards. A synopsis of leaks put together by The Inquirer suggests the Wii's "Broadway" CPU will feature a superscalar architecture with six execution units, a 729MHz clock speed, a 64-bit wide 243MHz memory bus, and 256KB of integrated cache. If the specs that have been leaked to the internet are close to what the final hardware will be, there will be an abundance of games the Wii simply won't have the capability to run.
CPU (Broadway)
- Superscalar microprocessor with six execution units (floating-point unit, branching unit, system register unit, load/store unit, two integer units)
- Operating speed of 729 MHz
- Bus to main memory: 243 MHz, 64 bits (maximum bandwidth: 1.9 gigabytes/sec)
- 32-kilobyte 8-way set-associative L1 data cache (can set up 16-kilobyte data scratch pad)
- Onboard 256-kilobyte 2-way set-associative L2 integrated cache
- Supports three L2 cache fetch modes: 32, 64, and 128-Byte
- DMA unit (15-entry DMA request queue) used by 16-kilobyte data scratch pad
- Write-gather buffer for writing graphics command lists to the graphics chip

GPU (Hollywood )
- Operating speed of 243 MHz
- 3 megabytes of embedded graphics memory
- 24 megabytes of internal main memory
- Internal main memory operates at 486 MHz
- Maximum bandwidth between GPU and main memory: 3.9 gigabytes per second
- The GPU of the Wii is identical to the GC's but it is on average 1.5X faster

Other details
- 64megabytes of GDDR3 external main memory
- Internal non-removable 512MB flash memory used as storage for game save data and downloadable content
- The following interfaces are included with the Wii: SD card slot, Wireless controller, two USB 2.0 ports, wireless LAN, 4x GC controller ports, 2x GC memory card slots and an AV multi output jack (analogue only)
- Two main disc types supported the single sided 12cm single sided 4.7gb and the double sided 8.51 GB. Nintendo GC discs also supported. The maximum read speed is the equivalent of a 6 speed DVD

The Wii games will cost around $50, which is much less than those available for the XBOX 360 and the upcoming PS3.
