[citation][nom]marciocattini[/nom]Better tesselation, reduced die size, higher clock, the list goes on mate[/citation]

you forgot to mention that its only worse right now, a few driver updates, and it may be significantly better, and by significantly, i mean you can tell the difference.
 
[citation][nom]doive1231[/nom]The ASRock 775 Dual VSTA had PCI Express and AGP slots but had only 8 lanes. Can be done though.[/citation]

No, the AsRock 775Dual-VSTA has 4 PCIe lanes. I've read the Radeon HD5770 works with the latest PC Treiber 3.19a custom Bios, but they have stopped updating the Bios, so nobody really knows if these new cards will work with the board.
 
[citation][nom]marciocattini[/nom]Better tesselation, reduced die size, higher clock, the list goes on mate[/citation]

Yes, but only improved tesselation can account for higher than expected TDP. This card will have a 128-bit memory bus, as opposed to the 256-bit in the HD6850. Add to that the reduced die size, as you say, should actually contribute towards even lower power consumption, right ? The higher clockspeed should should not influence much because this is a full node (40nm -> 28nm) improvement, and, as has been stated, this card performs between an HD5770, which works at 850 Mhz and has a TDP of 108w and an HD6850, which has a TDP of 127w.

Also, don't expect more than a 5-10% overall driver improvement over the commercial lifespan of the card (http://www.tomshardware.com/reviews/amd-catalyst-driver-performance-increase-radeon-hd-5870,2872-11.html).
 
"The HD 7770 is set between the current HD 6800 and HD 6700"

Realy?
Does it make sense that a 'larger' number is not the bigger, newer and more powerful toy ?
Or is this a typo and should be a 6770; which would than fit nicely into the numbering system.

Could be anything mate, more Stream Processors, ROPs, Texture Units, Increased Clock speeds...
The new 7970 performs faster, has a larger memory bus and still maintains the same tdp as the 6970...
http://www.tomshardware.com/reviews/radeon-hd-7970-benchmark-tahiti-gcn,3104.html

The 7770 performs worse, but close to the 6850, its got a smaller memory bus and probably uses much less power than the 6850 and about the same as 6770. Whether its tesselation or any of those components drawing more power I don't know... I think it could be anything, but there is improvement I'm sure!
 
[citation][nom]BeetlejuiceGr[/nom]Damn, so i am sticking to 5870 and will change at 8000 ati...in 1 year or more..[/citation]
I have 2 5870s so once again no need to upgrade, thank you consoles
 
The thing about these releases is they are not really for people who already have 5xxx or 6xxx cards, sure you can if you wish but the difference between HD5870 and HD7770 wouldn't justify the cost, but someone upgrading from a 4xxx card would see a lot of performance benefit and 4 years since 4xxx cards means cost over time isn't so bad.
 
[citation][nom]Achoo22[/nom]AMD's new cards are complete failures, simply because they don't represent a true generational leap. The new 7850 should be faster than the existing 6850, especially if it's going to initially retail at roughly the same price. AMD has lost their bang-for-the-buck advantage in the video card market, and unless NVidia changes things up in a hurry, my next graphics subsystem will probably end up being integrated Intel in 2014 or so.Voodoo Rush->Voodoo 3->overpriced crap->6800gs->8800gt->HD6850->overpriced crap so far. Show me the next 8800gt, please, or lose me forever.[/citation]

The 7770 is a large performance jump over the 6770/5770, almost to the 6850 and it still managed to lower it's TDP slightly below the 6770/5770. How is that not progress? How is the 7970 a failure? it beats the GTX 580 by 10-25%, a considerable margin if you think about how much faster the GTX 580 is than the Radeon 6970. Even with the huge performance increase it managed to keep it's TDP in the same area as the 6970.

I don't see how any of this can be a failure. AMD made a great leap in graphics performance without increasing power usage and isn't that what progress in tech is? Obviously AMD's CPU performance is dismal (to say the least) but AMD did well on these graphics cards.

I would like to see what Nvidia has going but they are keeping quiet so that's not an option for me right now. Chances are they will top the 7970 with their next flagship card (GTX 680?) but the comparison of Radeon 6970 and GTX 580 didn't make AMD a poor option for gaming graphics so I don't think it will be a bad option should Nvidia have something that will top the 7970 similarly.

Besides all this you seem to claim that the 7850 won't be faster than the 6850. That is completely false and is an idiotic claim based on all the information we have been given about the 7000 cards. The 7770 is much better than the 6770 so I would assume the 7850 is also much better than the 6850 since it is based on the same micro-architecture as the 7770 and all other Radeon 7700/7800/7900 cards.

You also claim that AMD has lost their bang for their buck in their video cards, another false claim. Next you say that your next graphics may be integrated. Sorry but I don't see what any of this has to do with that. The only integrated graphics fast enough to play modern games is AMD's Fusion APUs. Right now that would be Llano but Trinity is coming out soon and is supposed to blow the previous Llano chips out of the water in graphics and CPU performance. AMD claims somewhere around 50% gains in both if I remember correctly.

Other than that you would be stuck with Intel's graphics or even worse, integrated graphics on an AMD motherboard.
 
my ZXSpectrum ZX81 chipset-based {by Sinclair} used while working at my home bench.

Commando 3 has arrived! so what do u suggest new 7700 or nvidia  650I ?
 
This card is great value. Let's look at the 3DMark 11 X score of X1077 and a graphics score of 965. For perspective, lets take my 2600k at 4.6ghz and a 580 at 875mhz core. It scores a X2351 and a graphics score of 2133.

So the 580's X score is 2.2x the AMD card at 4-5x the price. The graphics score is only 2.2x as well. That's just looking at 3DMark 11 though, a synthetic benchmark. From this though, I'll have to conclude that the new AMD 7xxx series cards will be nice bang for the buck.
 
[citation][nom]trialsking[/nom]I have 2 5870s so once again no need to upgrade, thank you consoles[/citation]
Consoles are indeed holding us back, but I'm still upgrading from my 5970, because while it may crush anything on a single monitor, Eyefinity is still nearly impossible to run on full spec dx11 titles.
 
[citation][nom]tpi2007[/nom]Is it me or the TDP is a bit weird ? The HD6850 has a 127w TDP and is made using 40nm technology.This HD7770 is built using 28nm technology, performs slightly worse and it's TDP is only 27w less ? Is it because it has much better tessellation or am I missing something ?[/citation]

In technological thinking, that is a 25% drop in TDP on a immature arch. 25% in technology is often massive improvement.
 
100 watts and Is this card to be 2 gb ? Also really people those are the only things your gonna buy this card right? Between 6850 and 6870 is only a few frames per second . So what is really an upgrade , also did they actually test the 7970 @ 8 x bus not 16x for a reason ?? The only reason one should upgrade is if there old card is dead or won't play the games they want so why should AMD sell and build cards that are leaps and bounds over previous?
 
[citation][nom]old design[/nom]so why should AMD sell and build cards that are leaps and bounds over previous?[/citation]Because we STILL can't average 60 FPS in Crysis on enthusiast quality at 2560x1600.
 
The difference between PCI3 and PCI2 in games is about 0.3% or something... in high end gards. In pure mathematical aplications it is 2-3% max... So it does not matter if you have pci3 or pci2...
 
[citation][nom]popatim[/nom]Dont forget thay probably testing this on pcie3 so expect a performance hit if you stick it in a 2.x slot. What did they say v3 was, a 20% bandwidth increase?[/citation]

A bandwidth increase can only improve performance if the bandwidth was a bottleneck. There is no such bottleneck, even with high-end cards. A mid-range card cannot possibly saturate all the bandwidth.
 
Thought about upgrading to a 7700 series card from my 5870 due to the price point of the 7970 but after looking at this I will have to wait to see how the 7800 series performs...
