Report: Wii U RAM is slower than Xbox 360, PS3


White Wii U console

Update: The staff of PC Perspective have posted photos and video of the teardown on their website. Click here for details.


2nd Update: A second Wii U teardown has been done by Anandtech which estimates the main memory bandwidth may actually be 12.8 GB/s


3rd Update: The post on NeoGAF has been updated and now says the main memory bandwidth is 12.8 GB/s. The 17 GB/s figure was an estimate based on the maximum speed of Samsung RAM.


Original Story

According to a post on NeoGAF, someone has already cracked open a Wii U to try and find out exactly what's inside. There's no word on the CPU yet, but they did find out a little more about the system RAM. Here's a breakdown:

RAM
-2GB of Samsung DDR3 RAM
-1.5 V power consumption
-17 GB/s "at most for main memory bandwidth"

Nintendo had revealed the Wii U had 2 GB of RAM, but they have been very tight-lipped about the actual specifications. A memory bandwidth of 17 GB/s is actually slower than that of the Xbox 360 and PS3 as you can see from the following figures.

Xbox 360 = 22.4 GB/s + eDRAM for framebuffer
PS3= 25.6 GB/s main memory BW + 22.4 GB/s graphics memory BW, no eDRAM

I would like to emphasize that this information comes from the NeoGAF forums, and the original posting about the RAM findings came from the beyond3d forums. No authoritative sources have been able to confirm these findings yet. Nevertheless, many gaming sites are reporting this information and it is currently the hottest story on n4g.com. The post says "they ought to have high res photos later," and I'll be interested to see if they actually do post some images of said RAM. If they don't, I'm sure someone else will.
