Wii U RAM has 17GB/s bandwidth
A tear down of the Nintendo Wii U revealed a little bit more about the console itself. The memory chips are produced by Samsung and they revealed more details on the system’s raw horsepower.
The system uses RAM chips that appear to have 17GB/s at maximum for main memory bandwidth. It appears the RAM is DDR3, but it could be GDDR.
If you want to compare the Wii U to current gen consoles you should note the Xbox 360 has 22GB/s memory bandwidth.
These specs are for the whole 2GB of memory inside the system. The video memory appears to come out of this 2GB as well. There are currently no estimates how much, or how effective the eDRAM is.
We’ll update with more details as they become available. This is a little disappointing on paper, but I’m not well versed in exactly what these numbers mean.
