I was wondering if Nintendo was ever going to fire back at the naysayers about the Wii U's power. While they still won't give us exact benchmarks and specifications, they stated rather plainly that Dev Kits that actually took advantage of the full power of the Wii U were not even available until the middle of last year. That means all those launch titles were made on inferior kits that don't show the true potential of the console. It also makes all developer quotes referring to any Dev Kit before the middle of last year practically invalid as it's not a true representation of the Wii U's capabilities. Wait, don't believe me? Just read about it from arguably the three biggest men at Nintendo.
Miyamoto: For High End graphics there is a hurdle, since we have to reeducate our people. The development itself hasn’t changed but we are recruiting specialists that can become core members in each specialized area. External Developers are used to shader techniques and we are collaborating a lot with external companies nowadays so we have a very good development structure.
Iwata: Every gaming hardware has its specialties. There is a timing of hit and miss before the functions can be used fully. We were not able to provide development kits that get out all the power of Wii U until mid of last year. With other gaming consoles firms had 6 to 7 years to experiment but our console has a different balance so it is easy to see who has adapted and who hasn’t. However this is something time will heal so we are not too worried.
While this doesn't mean the Wii U stacks up with the most recent speculation about the PlayStation 4, it does show that the Wii U's true capabilities are not known yet to many developers. They are putting more stress on the memory and thus, the eDRAM is going to play a significant factor in how well the transfer rates process in order to maximize potential. It's definitely a cost effective way to get some good power out of the tech, but no one will really know how it holds up for the future until we see game comparisons across platforms.
Takeda: Wii U is a machine that has a lot of performance compared to its power consumption. The GPU is definitely more pronounced than the CPU. There are people saying that the CPU is weak but that is not true. It is a trend that the cash memory is what’s getting bigger with CPUs, not the processing power. I do not think at the CPU is underpowered. Its just a design where the memory is more stressed.
