[citation][nom]SteelCity1981[/nom]The thing i hate is the rebandage gpus. I mean if you want to talk about truly the falsification that's falsification and i'm surprised their hasn't been a class action lawsuit in regards to rebrandaging the same gpu's by fooling consumors into thinking it's a newer gen gpu when it actually isn't.[/citation]
There are always differences, even if they are minor and/or won't be used by many buyers. For example, the 6770 has support for Blu-Ray features that the 5770 does not. There are other such differences with pretty much all re-badges.
[citation][nom]Albert Shyu[/nom]Does anyone has tested the separate audio stream with HDMI/DP port function on HD7K series?? It's fun. But, why do this?? I have tried to output 3 video stream to 3 monitors and all of them can have their own audio output. Just for fun only. Never do that again......@@[/citation]
It's a very useful feature for video conferencing.

A PC is a computer running Windows. If a laptop is running Windows, it is a PC. You ment desktop when you said PC. No, the two terms are NOT interchangeable.
[citation][nom]madooo12[/nom]so if there is potential for power improvements, why not apply them for desktops?the mobile part MUST perform less to consume less powerBTW nice to see AMD focusing more on mobile stuff[/citation]
The mobile power improvements are done because they actually can be done there and must be done there (IE, pretty much all mobile computers have an IGP even if it isn't used so they can have switchable graphics and such implemented whereas not all desktops have usable IGPs, so it's not always an option for them). Remember, decreasing clock frequency and voltage exponentially decreases power usage despite it not decreasing performance too much, so lower end parts are always more power efficient than higher end parts. Compare the power efficiency of the Radeon 5770 or 6770 to the 5870 or 6870 and compare the performance differences too.
Then there's also the point that Pitcairn is far more power efficient for gaming than Tahiti because it is less compute focused than Tahiti. These mobile 7900s are based on Pitcairn, so they're more gaming power efficient at the sacrifice of compute power efficiency than they would be if they had been based on Tahiti.
All of these combine to help the mobile power efficiency. Then comes the real power efficiency tweaks to further improve this.
[citation][nom]A Bad Day[/nom]Let's see if AMD rebadges the lower end 7000's GPUs...[/citation]
AMD already told us that the low end Radeon 7000 (7600 and below) will be VLIW5 cards. They might not all be re-badges, but at the least, they are based on the older architecture from the Radeon 5000 and most of the Radeon 6000 cards (only the desktop 6930, 6950, 6970, and 6990 were VLIW4 instead of VLIW5. All of the mobile Radeon 6000 cards were VLIW5).
These high end mobile graphics look like they could handle 1080p very well. The 7970m looks like it should perform between a 7850 and 7870. Mobile gaming is going to be getting a pretty good overhaul. Now, what remains to be seen is if we will actually get good games that can push mobile gaming back into it's niche... Just kidding, but it'll probably happen anyway.
The R4s with 7970m is out with base price of $1899.
