I have been reading forums for awhile, and during E3, I was shocked at just how good looking Mario Kart 8 was during the Best Buy event. Reports at the time had Killzone Shadow Fall struggling to get 30fps while Mario Kart 8 can do 1080p at 60fps. I like many people were looking for answers.
Then Shin'en revealed about the edRAM for the Wii U, which was the secret weapon for the 360. While the 360 only had 10MB worth of EDRAM, the Wii U had 32MB
Here's the kicker; you only need 16MB to be able to render in 1080p.
Well, great, but why is the Espresso CPU so slow?
While a valid point, as some posters on Gamefaqs pointed out, the low clock speed of the Wii U is deceptive
Over ten years ago, Apple in a keynote explained the architecture of a CPU. This is where the popular phrase "Megahertz War" came about.
As Steve Jobs said in the video, how could a CPU with half the speed can be twice as fast?
What does it have to do with System Wars?
There has been a lot of misinformation and marketing spin that's been polluting the internet. When people claim the PS4 to be the most powerful, they would point the clock speed of their CPU and the 8GB of GDDR5 RAM. Here's the problem, the Wii U's Espresso is running on 4 stage pipeline, while the Jaguar is running on a pipeline 4 times as long at 16. In the video, they point out that Pentium 4 running at 20 stage pipeline while the old G4 processor is running on 7 stages.
I'm just a reporter with no knowledge, but even I find the video to be far more enlightening than words can ever explain. In essense, do not discount the Wii U on clock speed alone or it would bite you in the back
