So we know whatever the wii u does it does it by only transferring a maximum of 12.8gb/s. That figure of 12.8gb/s is shared between both the operating system side and the game side and the only additional bandwidth is in the 32MB of fast memory built into the gpu. 12.8gb/s is tiny compared to the 192gb/s of a ps4 for example. Memory bandwidth is a good rough guide regarding a console's performance because it would have been selected on the basis of the requirements of both the gpu and cpu of the system and how much data they can move. Clearly not a lot with the wii u sadly. |
Which is a pretty big boost because (A) 32MB is overkill for a 720p system, 360 got by with only 10MB, even after triple buffering to eliminate all screen tearing, there is still eDRAM to spare on Wii U, which brings us to (B) both the CPU and GPU have access to the eDRAM for operations that require fast memory access.
