as u can see it has 720 shaders/700mhz stock core(Max 870 on overdrive)/1150mhz stock memory(Max 1430 on overdrive)

What the hell is this anyway??

those specs say it's a 6750 not 6770.

its a 6750, just a tier below 6770, and "720 shaders/700mhz stock core(Max 870 on overdrive)/1150mhz stock memory(Max 1430 on overdrive)" etc are the specs of this card.

This is really disturbing! It's so hard to get info on this card too! I bought it only because I wanted 6770 DDR5 so bad.. & it was the only one available at the market which was at this price! It was a bad choice to choose powercolor.. I will never get one from them again I guess.. I feel deceived! Ironically they don't even have the page for exactly this one on their official site either!

its probably the stores fault. they must have slipped a HD 6750 for the price of a 6770 or maybe its polor's fault.

Whenever u buy any tech product the first thing that u should check is the part number/model no.
And compare some specs for additional confirmation

That 6770 is probably underclocked to consume less power. Does it require a 6-pin connector? It must be having cheap fan and heatsink due to that advantage and making the total cost cheaper

Dude.. I didn't buy it from this site.. This model can be barely found on any site at all.. not even the official powercolor website provides info.. & besides I just decided upon benchmark scores that I will buy a 6770.. thought of a xfx or sapphire one.. but they were out of stock the day I went to buy it.. I didn't have the idea that a 6770 can be rebranded model of 6570 instead of only 5770.. If I had any idea like that I would have bought GTX 650 which is the nearest likely choice in that price range!


Ya like u said.. it has got a 6-pin connector.. nd really the fan n heatsink is cheap as hell!

As I din't know anything about a Green edition card.. nd did not have any idea about it.. nor did the box helped when I bought it as U can see there is no info that could prove it's not a 6770!

I said it's an underclocked 6770 and not a 6750.
To really see whether it's a 6770 and not 6750 type dxdiag.exe in Run and check the display tab, there u will see chip type which is the actual chip that is used and not labeled by the powercolor manufacturer

It's underclocked so they could use a cheap fan making it cheaper

@chimera201, even if the card is underclocked, which it probably is due to being a green edition one according the the box, its still has a core config of HD 6750, not a 6770. if it was a 6770 he would have had 800 shader's but from the pic in his op, it has 720 shaders which HD 6570 has.

@chimera201 oh yeah its mem bus is 128, it should be 132... damn.but even then he had no chance he bought it from a store, he didn;t have the scope to check the specs and verify whether its 6750 or 6770.

He could have atleast checked the part number it's written there on the bar code. Part number is the only way to uniquely identify a tech product

Same thing with PSUs. Corsair has made the low quality VS series PSUs that's only available in India and China. Since it operates at 220-240V u won't find any reviews of it since Americans operate at 115V

@chimera201 i thought american's operate at 240V. i think your confusing them with japan, as they operate at 110V? anyways its no use blamng im as i also would have done the same thing. and the box clear says that its a HD 6670 so it wont be no use using the number from the box's barcode will it?

No Americans operate at 115V and so do 80Plus certification labs(the loophole :) )

I always look for part number since i know about these jhols quite a few years ago. I always want the model that i intended to buy and not be satisfied with what i get.

Even if I searched again the part no that is AX6770 1GBD5 HV4.. I couldn't have checked it.. as the model has just a few references.. none even tell that it got 720 SPs.. I would have guess that something's wrong by that as I knew 6770 has 800..
U can check it guys.. as Powercolor doesn't have it's details.. the majority sites that sell this card are from some other regions. sites are non-english.. nd the only one I got that is flipkart from india.. it got the actual powercolor regular 6770 which got 800 SPs but has the part no of this one! & Anyways it doesn't matter now.. I guess I will have some data connection on my phone next time I go to the market to buy something so that I can cross check the part no! And I will stay away from the product I don't find any review on!

The chip is 0x68BF

That's exactly what u need to look at. The sign of a 'jhol'.

lol..... That's interesting. Does all AMD cards show hex numbers like that. Because


I just googled for 0x68BF and saw that many people are having problems with this in gaming

Also the flipkart version
http://www.flipkart.com/powercolor-amd-ati-radeon-hd677...
Atleast it does specify the part number
And those 5 star reviews.....lol. People have no idea what they have

It's confirmed. The one u have is a 6750
Model:HD 6750 GPU Device Id: 0x1002 0x68BF
Model:HD 6770 GPU Device Id: 0x1002 0x68BA

No wonder why it showed hex numbers so that people won't find about it

The flipkart version, the image doesn't show the Green Edition. So the 5 star reviews were right after all. Only that Flipkart needs to present accurate data

I want to know whether all official AMD cards also show hex numbers in the chip type. If it does then AMD is also involved in this racket.

This 'rip off' was cleverly designed. Selling a 6750 under the name of 6770 Green Edition but at the price in between 6750 and 6770 is a rip off(not at this time since the cards are outdated). Since it's a Green Edition people will think that it will perform a bit lesser than the 6770 reference card. And they clearly hid the '6750' everywhere so no one can easily find that it's a 6750. Hex numbers for model no.s clever trick

Another option is to open up the case and take a look at it. The model number could be printed on the PCB. And I disagree with the PSU part. I'm from Singapore, and we use 240v ( I think ) . I'm using the Seasonic S12 II 520 watts. It's fine. Some PSUs can switch between the lower voltage and to the higher one.

Got a Zotac 550ti DDR5.. a friend of mine was having power issues with his 550watt PSU.. so he exchanged with mine :)  Bye Bye Powercolor!!

Thanx for being optimistic but its no use.. the No matches with the box.. I am done with them!
