Triple the CPU Speed and getting 60% more out of the GPU is way too much to be believable. Since the numbers are insane I think the guy has no clue about what he is talking.

This is just too big of a jump..


We all know it's likely a pile of twoddle.

But people are discussing if it's theoretically possible, which it definitely is with what we know currently. We don't know if the current cooling system is designed for it to run at 3Ghz+, we don't know if the CPU is actually specced at 3Ghz+, same for GPU.

Easy way to find out is to take a temp reading from the CPU when playing a game. If that temp is in the high 60c or above and the fan is spinning at a reasonable speed, it's not physically possible that the CPU could run at 3Ghz, even if it was actually a 3Ghz CPU. :)

...of course it's not that easy, but any person technically decided to find out if this is possible for a fact could do so.

It's actually an illusion, the overheating problem in hot countries.

Something that has an inherrant design flaw like the original Xenon Xbox 360 will have RROD accelerated by a higher average ambient temperature - yes. But, an electronic device that isn't flawed will not suffer any bad consequences from being used in a "hot" country, think about it, let's say it's 20c in the UK which isn't exactly hot but not cold either. Then take a country like Brazil where you reside, where I imagine 30-35c is pretty much standard.

That's only 10-15c increase in ambient temperature which translates to a 10-15c increase in temperate of your electronic device.

In the case of a standard CPU, most are good for at least 85c running 100% load 24/7.

So, back to the electronic devices using those CPUs, the Xbox Slim has a cutoff point where the fans increase considerably when the CPU reaches 80c. The standard cooling system built into the Xbox Slim is capable of easily taking that temperature down to 55-60c with increased fan speed. I know this because I have an RGH Xbox 360 which monitors all temperatures of CPU/GPU/RAM/Ambient. At "auto", which means the Xbox 360 is controlling the temperature it will reach about 75c, if I control the fans myself and put them at say 65%, that temp goes down to 55c-57c.

This means that the built in cooling system is easily capable of keeping an Xbox Slim adequately cooled anywhere in the world.

I imagine that the PS3 cooling system is equally as adept, since the PS3 slim fan noise has a massive variation in noise output.

 

:)

Most consoles have trouble with temperatures here in my country... in PC the cooler box have trouble too, so we use better cooling system.

My PS3 Slim when the temperature is so hot freezes a lot (playing the game and it freezes) but when it more cool they never do that... when I put a fun to cool the things I have no touble too.

So the country temperature matters.

Sorry but true.

I saw a lot of guys losting PS2, 360 and PS3 due overheating... my PS3 Slim freezes in high temperature days.

Overheating with PS2.

Fair comment, I can't exactly say you're wrong if you have first hand experience with this. It does sound quite bizarre though. I used to overclock a lot of stuff years ago on the PC and ambient temperature does matter when you are already on the edge of what the CPU/GPU can do, but if you're already in the safe zone then things shouldn't be freezing up, no matter the ambient temp.

If you check the PS3 packaging, it will list it's safe operating temperature in the back of the manual no doubt (can't find mine). On electronic goods, this is generally at least -5c to +40c and obviously there would be a buffer of a few degrees either side to ensure that claim is upheld.

Still, appreicate the response...why I do I never agree with anything you say...strange world :p

get watt meter and measure power draw before actualization and after it is simple as that

PS2 is certainly a different matter, I'd a agree with you there actually. It's well documented that most of the PS2 models are not cooled sufficiently so that would be a design flaw.

The issues not happen in little time... eg. the AMD cooler box here makes the Windows freeze after some hours of use... so you just change the cooler for a better one and the system never freezes even when running over 24 hours.

These cooler box tested by AMD works for most countries but not here... the Intel coolers are a little better but not enough to make overclock.

I use some App to stress the system for some time (30 minutes or more) when I do overclock... my mother PC can't pass the tests with the cooler box with 100Mhz increase in clock but after I changed the cooler I can overclock until +500Mhz without problem... the issue is the overheating.

My PS3 Slim freezes in crazy hot days... and not in normal days... below a video with PS3 overheating.

@fillet

You can found a lot of cases in forum about PS3 freezing due hot days here.

"E bem, o meu PS3 já travou algumas vezes, na maioria das vezes após muitas horas de jogo, e em dias muito quentes. Se o seu PS3 fica num lugar muito fechado, mude-o. Se não der, ponha um ventilador perto dele ou jogue menos"

Translation "Well, my PS3 already crashed a few times, most often after many hours in very hot days. If you have a PS3 in a very closed place, change it. If not, put a fan near it or play less."

http://www.soniczone.com.br/forum/index.php?/topic/19150-ajuda-ajuda-com-ps3/

It is really common here to put a fan near to consoles to not have trouble with overheating... the companies design the cooling system in consoles (and all eletronics) based in Europe temperatures... not Brazil and others hot countries.

The flaw in your earlier reasoning is that an increase in 15dgrees in ambient temp does not simply mean an increase in 15 degrees in your electronics temperature.  There is a direct relationship between rate of heat transfer and difference between two temperatures.  So if we go from a 20 C region to a 30-35 C region, there is a significant reduction in the difference between the device temp and the ambient temp.  That means not that the device will be hotter, but that heat will leave the device at a much slower rate.  This could cause a greater rate of failure.  Since circulation dramatically increases the rate of heat transfer, adding fans would help.

Why shouldn't it be? The PSP also did this.


PSP was underclocked by default for power reasons.

That is to say it was running under specification so clock speeds weren't "increased" they were just set as high as they should have been in the first place.

Don't know if that's the case with the Wii-U, incredibly unlikely, or unbelieveable (genuinely, not in the "amazing unbelivable" way.)

Going from circa 1.5Ghz to 3.xx Ghz is just asking a bit much to take seriously that Nintendo would have released the console at only 1.5Ghz considering the moaning the low CPU speed has caused and being responsible for the frame rate issues in the current ports.

There's no reason for the Wii-U to have been underclocked like there was with the PSP, power isn't an issue obviously as it doesn't run on batteries.

Pretty much ever processor ever made is "underclocked".  They do this to keep reliability.  I'm not saying that Nintendo could increase the speed by much, but with a firmware update, they could run the processor at a slightly higher speed if they are comfortable with the stability and reliability at that speed.  Though, it doesn't sound like something Nintendo would typically do.  Nintendo would rather under power the system than have a RROD or YLOD issue on their hands.  They tend to always play it safe with hardware and for that reason pretty much always have the more reliable systems in the industry.


uness they just finished testing the Wii U at those high frequency, with an equivalence of time of about 5-6 years of use. 

Remember when they said they tested the Wii U for arund 2000hrs if i remember correctly? well they might just conclude that it was safe.

I live on Arizona, it is summer right now with temperaturesabove 38 Celcius, and the Wii U is just as cool as tap water. So i suppose it can handle more than that.

remember, the new tech on the Wii U will allow higer frequencies with less heat output, comparing it with the 6-7 years old xbox and PS3. You just need to see the new slims editions. but the architecture of those systems did not allow heat to be dropped more. 

But people is right here, it is too much of a change for Nintendo to be using so much less at launch.
