You state all this as if it were facts. You should really prepare yourself for disappointment if you believe the Wii U is an entire league more powerful than the HD twins.

Devs don't have much experience on PS4, yet they ported the PC assets and improved many aspects of Tomb Raider... The scenario you're making up would make sense only if the Wii U didn't have much more horsepower than the HD twins. But the way you present all this indicates that you believe it's actually in an other league... Which so far has been proven to be false, even when you consider the exclusives.

Does it really need 7 years of experience when almost everyone in the industry already knows what it's hardware is and/or already has the tools ? 

Think about, curl ... The IBM espresso is just an overclocked gamecube processor with two more cores. The GPU is just from some evergreen family with no architectural modifications to boot. How hard can it be to program on it ? If it has better support for GPGPU like you mentioned then shouldn't it be much easier to program on it seeing as how you can easily use a middleware to expose the underlying functionalities of it on a high level abstraction layer ? 

Afterall one of the goals of GPGPU is to make concurrent programming models simpler. 

We can't say they know its GPU cos we don't know what the GPU is.

Broadway/Gekko didn't have assymetrical cores or such a heavy focus on cache like Espresso. But the main issue is that code built from PS3/360's high clock, low cache, long pipeline CPUs are being shoved onto Wii U's low cock, high cache, short pipeline CPU. It's a square peg into a round hole.

Even if the IBM espresso had high clocks it's still a very offensive single threaded performer due to the fact that it has such as low IPC. Caching is AUTOMATED NO MATTER WHAT and is not handled by the programmer and the cores aren't ASSYMETRICAL AT ALL. If you want assymetrical go and take a look at the cell processor LOL. 

Espresso's IPC is higher than Cell or Xenon, the guy who hacked it confirmed as much.

Cache handling is not automated cos Shin'en pointed out: "the workings of the CPU caches are very important to master. Otherwise you can lose a magnitude of power for cache relevant parts of your code."

And they ARE assymetrical; one core has 2MB of cache,the other two have 512kb each.

Actually it's lower because it has very weak SIMD engine and the SIMD instructions also don't extend to integers either which makes it a total clusterfuck in integer performance. Hector Martin also made the note of this but while he did express concerns of weak SIMD engines I don't think he emphasized it enough seeing as how he probably didn't forsee that engines became more and more focused on the thought of vectorization. It would have won in alot of cases but that's probably because it's more suited to actual CPU tasks that involves lots of branching but in HPC it would have lost because it doesn't have the raw performance that the CPUs in the PS360 offer.

Yes IT IS! Caching is not handled by the programmer AT ALL. Caching works on the premise of PREFETCHING and programmers don't know which way the code will branch so it is not up to the programmer to handle the cache. The best thing you can do to help out the cache is that you don't litter the shit out of your code with conditionals and branches otherwise that will increase cache usage which means more possibilites for stalls in the pipelines and such. 

Oh wow, one core has more cache than the other ... Like it makes huge difference. 

Curl, you're really not doing much to prove your point here.

But it's all good. You've said it yourself that the Wii U is just moderately stronger than the PS3 and 360. Making it a system that is in the same ballpark as those two. The same as the original XBox being in the same ballpark as the Gamecube and PS2, despite being the system with the most horsepower... ^_-

PS2 to original Xbox sounds about right to me; like Wii U, it had twice as much RAM as its Sony rival and a GPU several generations ahead.
