For instance, in a 2" notebook (Clevo X7200), you can cool 330W worth of TDP between two GPUs in a CPU whereas in 1" Apple is only cooling about 60W currently. This suggests the depth of the housing rapidly becomes your limiting factor.
The depth of the housing on the 21.5" is less than that of the 24" and we have no way of knowing if the 4670 is the max TDP GPU the current iMac can handle because iirc the only other option at the time was the 4830 which was a weird release because it was released after the 4850.

Yeah, which is kind of why it's a guessing game. Our closest point of comparison is the envy, but both the CPU and GPU are higher TDP on that one. If you do opt for the 35W CPU, there are fewer overheating problems, but then the GPU just dominates the issue. I feel their engineering team is capable of it, I just don't know that they see it a net benefit for their product line at this time.

Just because Apple did it with iMacs does not mean that they will do it with MBPs for sure. With iMacs, you don't have to worry about things like weight but that's fairly important when it comes to a laptop. Also, iMac cannot be used on a lap. Usually overheating occurs when using a laptop on a lap as the heat cannot dissipate as well and your body heat is warming it up as well.

It is possible but we'll have to wait and see.

21.5" iMac is 5 pounds lighter than the 24", 27" is 5 pounds heavier than the 24".

But I get your point. I'm not suggesting Apple start using the highest TDP parts possible in the MBP, not at all. I was simply pointing out that Apple has made an effort to increase performance in recent products while making them smaller at the same time.
 
So how exactly is this relevant in a thread referring to the 15" and 17" having quad cores? Oh wait, it isn't. The current 15" and 17" already use Intel's IGP alongside a discrete GPU and they will do the same for this upcoming refresh.

Wow aren't you rude for no reason. Your the one thinking your an engineer and that just because the wattage is the same that it magically means you can fit a quad core in a macbook pro.

What that poster said is very relevant to the performance of the machine. If you think its just the processor Apple things about you are very wrong and really know nothing about computer architecture.

LOL, when did I say was an engineer for adding up the watt usage? As has been discussed in this thread it's more than possible that Apple can use this quad core.

What the poster said is about as relevent as putting "I like chicken" in this thread. Apple does not care about how powerful the integrated GPU is on the 15" and 17" notebooks because they all have a discrete GPU beside them. Nor do they care if that integrated GPU has OpenCL support as proven by the fact that the current MBP's use Intel's graphics that don't support OpenCL. His post served no relevance to the topic at hand and you are clearly the one that has no idea about what's being talked about.

As I said before, you clearly have no clue about computer architecture. Especially from the line "Nor do they care if that integrated GPU has OpenCL support as proven by the fact that the current MBP's use Intel's graphics that don't support OpenCL". I will not elaborate any further. You can go to google for your answers. You are being nasty to people for no reason at all.

For sure Apple could use a 45 W chips as can all the other manufactures. There is no reason why HP, Dell, etc can use such a chip and Apple couldn't.

But It is always a tradeoff with battery life and even more important the "noise" due to the fans running. Usually Apple laptops are very very quiet. A 45W CPU could require more cooling and therefore more fans running.

What gets my hope up is the fact that this CPU can change its clock based on the load and that should require a lot less power consumption. I assume the 45W is a worse case and not an average. Not sure about that.

45W is the average maximum that can be achieved with commercial software. That is what the cooling system should be able to dissipate. Under the worst conditions, the power usage can be 20-30% more than the TDP but this is very rare (can be achieved with benchmark apps like FurMark).

Anand's test already showed that quad cores are very power efficient when doing something light.

Any idea on the power consumption in idle mode? Not sure about the idle clock speeds and I guess power consumption is not linear with the clock speed.

p = fcV^2 where f is clock frequency, c is capacitance and V is the voltage applied. Theoretically it is linear, but CPUs dynamically adjust voltages in addition to clock frequencies now-a-days.
 
I personally just cant understand why people are rabbiting on about the gpu and gaming performance.

if your into gaming:

a) you would not be using osx, you would be on win7

b) you would not be using a laptop, due to limitations of the gpu and no upgrade path for future gpus.

a) A very popular game runs on OS X (WoW) among others. Also, many people dual boot OS X and Windows. That functionality is probably what helped Apple achieve the number of Mac switchers there have been. I would never have gotten a Mac without that ability.

b) Some people like playing games at places other than their own home. Some people have friends.

A third point would be that some people use the GPU for things other than games.

LOL, so do you dislike me for the way I responded or are you trying to say what I said was wrong(which it wasn't)?

So how about you look up as to whether or not Intel's current graphics have OpenCL support then get back to me. The reason you don't want to elaborate on it is because you know you're wrong. The current Intel HD Graphics in the MBP's do not support OpenCL. End of story.

The current discrete NVIDIA GPU's alongside the Intel GPU, do support OpenCL. These are two separate things.

Around 4W according to AT

Apple usually delivers high end processors to its 17" MBP, it gives more power to it than all other MBPs. But, will the sandy bridge quad core processor available at 15" MBP??? :confused:

The 15" historically has had all the same processor options as the 17" (in fact more because the 17" doesn't have all the lower options the 15" does).
