Wii U has a DDR3 RAM which is something you normally find in desktop systems. Why is that bad? Because a console is supposed to have a long life and things like these can get really crippling after some point in time.
However, it is being reported that the system has 2GB RAM in total, which is quite good.
The Wii U has a Hynix memory which is slower than what DDR3′s maximum speed is, which is 17 GB/s. The Wii U’s speed is reported to be 12 GB/s which is half the speed of PS3′s XDR which has a memory bandwidth of 25 GB/s.
The Xbox 360 has a 22 GB/s memory bandwidth and has GDDR3 memory. So what’s the reason for Nintendo to do with such a slower speed RAM? Of course, it’s the price, they wanted to make it affordable, but when you consider it’s 2012 and the RAM is slower than consoles released in 2005, that’s gotta sting.
The console recently underwent a teardown at some sites and the Hynix memory was outed during Anandtech’s teardown.
