I wouldn't be surprised by fixed function hardware in the Wii U at all. They seem to be getting a lot more performance from the hardware than would seem to make sense on paper for a 160:8:8 configuration, if that's truly what it ends up being. Fixed function would be one way to explain that, but I'm sure there are others we haven't thought about. It would be nice of some kindly gent from AMD would come along and explain it to us.

somebody on TV tropes seems to think that the clock speeds of the system were increased after the most recent update
Isn't 3.24GHz really close to the PS4/720 CPU's? Or am I thinking about something else? And the GPU being at 800MHz is a lot better than what people thought before the Wii U released.
That is out of nowhere, where did they get that information?
iirc rumors/leaks put it at 1.6
For what?

very, VERY good question. The problem is that, even from experience, TV Tropes is VERY hard to source.
for PS4/Durango

achieving 1.24 to 3.24 isn't it kind of unrealistic? honest question.
Because some random on TV tropes should be trusted...........
It is also completely illogical to launch a home system that is running at clockspeeds so much lower than what it can run at then upgrade it's speed in a patch.
Please do not spread this information. It will NOT end well for anyone concerned.
Indeed.
EDIT: Assuming that the "unlock" is system wide and not "turned on" by games that want to use it.
Listen to this man.

Listen to this man.
Sony and Nintendo both have done this in their handhelds. Nintendo has even gone as far as unlocking cores and adding more RAM access on 3DS.
I however do not buy this Wii U rumor.

For the already released games? I don't think so. Remember the ps3 unlocked some extra ram via the os throughout the years but old games never noticed an increase in anything, it's just from games that came out after the unlock.

Well, PSP had that happen, but yeah. I'm still rather skeptical.
Handheld consoles run on batteries, that is why some are underclocked at launch (because higher clocks mean more power usage).
Home consoles do not have that limitation.
Is it feasible that they did it to keep heat down but later deemed it safe enough for extended use within the thermal ceiling, assuming the power supply could support it.

So, they increased the clock by 2.5+ times and increased the eSRAM 250Mhz?
And all of a sudden this heat sink is going to keep this thing cool? Yeah, I doubt that.

If clocks are running higher full time, then yes, even old software should see improvement.
I'm obviously going to wait until we get more info, and someone tests the power draw and stuff like that, but Nintendo made the OS have 1GB when we know later Nintendo will unlock half of that for the games later on, so it's possible Nintendo under clocked the Wii U for launch I think, we'll have to see of course.

I would REALLY like to know who there "hackers" and "homebrewers" are. Maybe he's referring to the WiiKey dudes?

exactly.
Nintendo may have underclocked because their tools weren't ready or their OS wasn't ready, which clearly it wasn't and still isn't.
No, not unless they made some huge mistake measuring the heat and power draw when making the system.
Freeing up RAM usage for newer games is not like changing the clock speed at all!
It has nothing to do with hardware and is just about optimizing the RAM usage of some system services.
It has nothing to do with tools or the OS!

Not taking this seriously yet.
The 3.24 could mean the total amount, so the CPU was lowered 1.08 each (stability issues????).
The GPU at 800Mhz I think that is possible (GPGPU???).
RAM is different than CPU. A games RAM usage is locked and set, unless a patch is made.

I forgot the ps3 only received the benefit of increased ram, not clock speeds, my bad.
I would be shocked If there any "fix function" beside what in there for bc.
Just no power left or any sign of it. It's only wishful thinking.....
Really the wiiu is very impressive for it's power consumption. Just the CPU in the ps4/720 will use more power than the wiiu system.
Easy way to test is just check power consumption or does it feel hotter.
I wouldn't even take this serious without a power draw test, does no one really have a measuring device for the task?

Yep. I believe it!
All someone needs to do to confirm or deny this is check the power draw. You can't just increase the clock that much without increasing the voltage...
Can anyone test this?
You read my mind. ;]

Yes, even if just for power consumption reasons alone, not to mention heat.
The Wii U runs pretty cool though. Still, no way they doubled it. If there was any clock boost, it at best would be to about 1.6Ghz.
Hmm?
Anyways, I'm not buying that "rumor". There's so much against it. That small console would suddenly have to be ready to keep itself from melting (unless, of course, Nintendo planned for it, which itself is unlikely).

I dont believe it.
But someone just measure the damn power draw.

I made an audible laugh.
"However, this guy said that judging by the PSU and airflow design of the system, Wii U could easily be clocked to 3.0 Ghz if not higher."
Heh.
honestly it could easily disperse the extra heat, it is more a problem with the PSU, you'd have to move the power draw up by ~20watts putting the console's power draw just under 55watts... sort of reaching that limit there. The casing and heatsink I assume are designed to handle the full TDP of 75Watts.
I have a metre at at home that can measure power draw. I'll check it in about an hour if noone else does.

Power draw does not scale linearly with clock speed.
