Hmm. You are seriously mixing up things the stuff you posted in that link is misleading or even wrong.

7850 has 130 Watt BOARD POWER.

"AMD advertises the board power at 130W (7850) and 175W (7870), board power is different then the TDP. If you try and visualize the power control settings slider in the Catalyst center, then you'll realize that you can increase it 20% meaning at default the TDP is roughly 20% lower then AMD's 130W for the 7850 and 175W for the 7870."

So 20% from 130 Watt is 100 Watt TDP. Thats the stock TDP of the 7850.

The board allows you to go higher if you want to. So yes the7850 has a possible max TDP of 130 Watt. Meaning the Card is designed to cool the GPU if you run it at the max. Take the GPU redesign Card/Cooling and it maxes out at 200 Watt TDP. 

Now the 7970m has usually not a TDP of 75 but 100 Watt. But It CAN Have a TDP of 75 Watt and what it actually has depends on the engineer designing the Notebook which is not AMD.

You are wondering right now why there are so many different numbers on the net, if you have googled it. 

Well see TDP is variable it depends on the clocks and the strength of the cooling system/power supply. If you "overclock" a 7970m to 1 GHZ the TDP will be 175 Watt and you will have a 7870 GHZ Edition in your Notebook.

See a Notebook clocks a certain chip higher or lower depending on the battery. If you have a huge strong one you can have the GPU running higher power.

Well a PS4 can use Powerlines so they will not use low power because it makes no sense. (Unless your name is Nintendo).

Low Power wafers are the ones with  30 Watt 10 Watt.

A Gefore Titan Can be considered a mobile GPU if you carry a backpack with Hydrogencells around. 

Its really die size and Transistor count that determins how big a GPU is not TDP. And the PS4 GPU is bigger and can far exceed the power of a Desktop 7850. 

Where does low Power begin for you ? Desktop ranges from 20 Watt (7350) to 375+ Watt (7990) max TDP. 

"The TDP is reference design TDP values from AMD. Different non-reference board designs from vendors may lead to slight variations in actual TDP." 

The TDP tells people how much Temperature can be transported safely away without the GPU overheating. You can freeze a GPU to absolute Zero and make it a Superconductor and feed a it insane amounts of Watt. You can do it with a mobile GPU aswell as Desktop GPU. 

So low Power is determined on how much Power a certain chip gets and where do you think low power starts what are the criteria ?

You have no idea how much watts a PS4 GPU will need but I can tell you with 1.84 Tflop its highest end mobile TDP and Midrange Desktop TDP.

The GPU itself is bigger than a 7850 so please define how the PS4 GPU is low power, low cost, mobile GPU ? Is everything not high end low power to you ? Do you think PS4 can run on a Laptop battery ?

Wrong info? Please show me in that thread.

No difference?

That's like saying a Toyota and Lexus are the same as they have similar base and company. There's a reason why the TDP drops by 1/2 between the desktop and mobile GPUs and its not just clock speed.

Yes, they have same basic features and can utilize the same tech. But one is significantly more powerful than the other.

Hmm i dont think hes read anything we have said. He still doesnt seem to get that the the 7970M and the 7870 are the exact same gpu. I don't really know how else to convince him.

Anyways, howcome i cant click on your profile :? I like your posts. They are much more clearer and in depth than mine!

I see that and get that.

I was looking at 7850 and 7970M and whether or not the "M" variant was more than likely the one in the PS4.

See other thread for where that is going... I think I definitely misunderstood how they display / rate TDP.

Ok to the question wether its  7850 or 7970m in the PS4, its neither. 

7850 is 16 CUs 7970m is 20 CUs PS4 is 18 CUs. Its also going to have an improved architecture (8 ACEs)

Its more like the 7790 with more CUs/ROPs/TMUs. 

PS4:
18 Compute Units (1152 Stream Processors)
800Mhz
32 ROPs
72 TMU
1.84 TFLOPS Single Precision compute power

7850 is 16 CUs but with bigger clock (860Mhz in reference models) catches somewhat.

So the easiest to compare it would be 7850, not reference ones with bigger clocks (900+) are faster.

Going down to 7790 makes problems with everything needing to be better....

There's a huge differene between 1080p and 720p. I can easily see the differnce in my 20" monitor on Guild Wars 2.
I imagine the difference would be massive on a 40" HDTV.

But you're comparing a moniter which I'm sure you sit mere inches from, to a Tv which people sit many feat from. Of course it varies on peoples set ups (how far from the TV they are), but Frame rate has a universal value, resolution does not. 

Really it would be usefull consoles provided you choice between the 2 as is the case for PC, when the option for maxing everying is not available.
