This developer don't seem to think that the wii u's RAM creates a bottleneck issue.

I am no technical buff but those in the know don't make that much of it's slow memory because of the eDRAM.
"One of the most interesting discoveries relates to the system's memory bandwidth which, at a peak total of 12.8GB/s, isn't too dissimilar to the Nexus 10 or the iPad 3/4. While this may not sound particularly impressive, it's worth noting that both the Wii U's CPU and GPU have a good amount of eDRAM at their disposal".
Let's face it, the wii u is no powerhouse, but it is not as pathetic as some people tend to make out.

Exactly what I'm saying, you don't need fast RAM.
As long as you have a cache on the CPU of reasonible size which all CPUs that aren't designed more for low power consumption do, and have done for years, there's no tangible gain in having a massive amount of system bandwidth except in rare situations that video games will never experience.

You're forgetting that the GPU also accesses the RAM in WiiU and the RAM speed makes a huge difference for the GPU. Just look at AMDs APUs and how the clock speed of the DDR3 RAM in the system can make all the difference to a games performance:

Even though the A8 3850 has a fairly weak GPU, the RAM speed is the bottleneck for gaming performance.
