Why Wii U is weaker than the 360 and PS3, explained intuitively.

Oh look, its one of those topics where people think they know alot about tech but they don't. Lovely.

Go on the Wii U board and find a topic where the word fanboy isn't used. Its impossible.

What's faster?

1. One guy with 6 arms carrying bricks at 3.2 feet per second
2. Three guys with 2 arms each carrying bricks at 3.2 feet per second
3. Three guys with 1 arm each carrying bricks at 1.24 feet per second

Both 1 and 2 seem equivalent, right? There are 6 arms in total, each carrying the same amount of bricks at the same speed. But with 3, there are half as many arms and they move far slower.

1 and 2 correspond to the PS3 and 360, respectively. The 360 has 3 physical cores, each with 2 logical cores - 3*2 = 6, i.e. 6 things operating in tandem with the same capability. The PS3 has a more unique architecture, with a single core called the PPE acting as a master to 6 slaves called SPEs, that receive and execute instructions independently. Since the PPE is mostly busy controlling the SPEs, we once again have 6 things operating in tandem at the same speed.

3 corresponds to the Wii U. Wii U has 3 cores, which cannot split into logical cores as the 360 CPU does. So only 3 things can execute simultaneously using this CPU. In addition, the speed at which things execute is nearly 1/3rd of the other two consoles (3.2 Ghz). So theoretically, Wii U is 5 times SLOWER than the 360 and PS3. The reasons it can push graphics almost equal to these consoles is:

- a stronger GPU (FAR superior to the others)
- less overhead (Though it can only push 14 GFLOPS compared to the 360's 115 and the PS3's 218, less processing power is spent on the numerous background tasks of more complex operating systems)
- more RAM, allowing more game data to occupy memory instead of being read from disk

I hope this has been educational for you.



I'm sorry but your logic doesn't cover everything.


1. One guy with 6 arms carrying bricks at 3.2 feet per second
2. Three guys with 2 arms each carrying bricks at 3.2 feet per second
3. Three guys with 1 arm each carrying bricks at 1.24 feet per second

When you look at your logic, the more you carry the faster you can process that data. But when you look at computer logic, it doesn't matter how many you carry as long as you can deliver whatever to the end result.

Three guys with 1 arm each carrying briks at 1.24 feet per second can be way faster than one guy with 6 arms carrying bricks at 3.2 feet per second as long as their path or whatever is a shorter distance than the 6 arms guys. Three guys with 1 arm can carry more than the guy with 6 arms with in a given amount of time if the three guys plan their path to maximize their delivery to the end result.

If you think about it it can seem that the PS3 is weaker then the 360 because the mulitiplates are made on the 360 and then ported to the PS3 with worse performence.

And yet ME3 runs better on the U than it does on the PS3.


A rare case where the Wii U's benefits edge it out.

CPU speed hasn't been relevant since the late 90's.

You know, you try to simply your example. Yet you don't explain at all what a Core does.

Go to DF, the framerate isn't as bad as the PS3 version.
