No, I did not.

.

apologies, I misunderstood what you wrote when you typed the OR, I thought you were just doing the math out for us. You were listing prices of two different cards for the 550ti then?
I guess it would have been clearer if you had linked to the cards you were referring to, it would have made it easier for me to understand.

Thanks for clearing that up!

5770 draws 50 watts less power than the 460.

You seem to have difficulty understanding that frames per second is not the only purchasing criteria for a video card.

And with the 6790 having the same power draw as a 6870, thats ok?

Do you not know the history of these cards? 465 using the same power as a 470. 5830 using same power as 5850. It's to be expected. Also, note, actual real-world power consumption tests have not been done yet, so we don't know where it exactly falls. A bigger crime is the 550Ti, a completely different and smaller chip, using as much power as the 460-768MB.

Your question is pretty pointless. It isn't particularly "ok", but history has shown us there is nothing we can do about these harvested chips. They are what they are. However he has a point. Also, your original comment about the 460-768 is so narrow-minded and limited. You don't include any quantifiers to back up your statement. As far as I know, a 5770 and 550 (or 450) are pretty much cheaper than the 460. They also use less power.

So ,I take it your answer is....... its not ok?

Why are you arguing about the price of a 5770 or gtx550 when the gtx460 768 is still on the market?

Anyone buying either of those cards needs there heads examined with the gtx460 768 still on the market.

I got my 5770 and GTX 550 cheaper than I could get a GTX 460 768MB for. Actually my Powercolor Radeon 5770 was on special offer and was the same price as the 5750.

I wouldnt get a 6790 because the price will IMO will be too close to the 6850 so wouldnt make sense.

Your missing the point, i'm leading you or whoever to the water and they can clearly see that the 5770 is not a 100 dollar card. If I had chosen 5 popular models , they show a similar price. You would tell me those aren't the popular models.
There are occasion freak sales that approach 100 after rebate, but not the norm.

Its hard to tell what point you were trying to make when you just throw out a seemingly random graph. Besides the fact that there are a few other models which are quite cheaper than the one you picked.
You were leading me to a bucket of water, while ignoring the ocean of other data.

If that power draw is okay on the 6870, why wouldn't it be okay on another card? The only power draw that wouldn't be okay would be a power draw that is high enough to destroy the card, which only seems to be the case with the GTX 590.

I don't get what point you are trying to make. Less power draw would be nicer, sure, but this is a budget level card when you are working in these price ranges you take what you can get. You pay more if you don't like the options, or settle for less performance.

Fudzilla is reporting that this will be a great overclocker (1,000mhz + ?). I think I am a bit more enticed now...

@Jionix,

your right, from Fud:

Our sources that are currently preparing for AMD HD 6790 launch have confirmed that the card is a great overclocker and that disabled shaders might even be unlockable.

As you already know, the HD 6790 is based on quite well known Barts GPU, the same one behind both cards in the HD 6800 series, and it even uses the PCB that is similar, if not the same, as the one used for the HD 6870 cards. The choice of HD 6870 PCB should explain the maximum value TDP of 150W and even the fact that it needs two 6-pin PCI-Express power connectors.

For now we can only confirm that the upcoming HD 6790 cards will have an insane overclocking potential, and we are hearing that 1GHz is possible and quite easily achievable. Bear in mind that partners will surely go for their own cooling solutions that should make those overclocking ventures even easier, and if the shader unlockability gets confirmed, AMD might have a really good card on shelves once it launch on 5th of April.

We'll keep our ear close to ground to hear if any of our sources manage to confirm the shader unlock rumour.
I think they used chips from the 6850, that didnt pass quality inspection,... ei. they needed more power to run same mhz as a 6850 chip of higher quality does.

Unlock? maybe... but that would make them draw even more power... these cards will be AMDs power hungry cards for its performance (amd cards usually have better performance/watt than most of the nvidia cards, this card is not gonna be on the high scale in that reguard).

I think this card will end up known as a value card, 460 768mb speeds (or better) for cheap price.


the fact that fud's sources are saying these babies go from 840mhz stock -> 1,000mhz no problem, sounds nice though :) (like a 20% overclock potential right there)

Just to say that AMD will release the following cards probably within April

R6770, R6750, R6670, R6570, R6450

Haven't the 6700's already been "released"?

Yeah those(6750-6770) will just be 5750-5770 's with slightly higher clocks (rebrand + oc), and differnt pcb... but basically same as the 5750-5770. Apparntly OEM products only too, I believe.

the 6790 is a differnt card.... it uses "salvaged" chips from the 6850's to make a completely new card (kinda like Nvidia did with the 460 SE).

It should have been named HD6830 IMO if it's using the same core as the other two HD68xx cards. I wonder about the price and performance too...

seems like (newegg prices)

nvidia :
460 1gb ~ 170$
460 768mb ~135$
460 SE ~ 140$

AMD :
6870 1gb ~ 180$ (a good bit faster than the 460 1gb)
6850 1gb ~ 150$ (tiny bit faster than a 460 1gb, at 1920x res, a tiny bit slower at lower)


So the thing has to sell for less than the 6850.... and it has to be between 130$-140$ depending on its performance. If its faster than the 460 768mb, or the 460 SE, it might force prices down abit.

Amd is missing a card in the 130$ slot, compaired to nvidias 460 768mb card.
So I suspect thats where it ll go.

we said the TDP of the HD 6790 would be of 150W. This is wrong. The real TDP is near 115W which is more coherent with the TDP of other Barts-based Radeon cards

Good news, so it wont have power use issues.

Evga gtx460 1gb SSC @ 850 core is 175$ on newegg and is faster then the 6870. (not by much)

Factory overclocked Galaxy gtx460 1gb is 139$ AR on newegg (with the factory overclock should be very close to a 6850)

Galaxy gtx460 768mb is 114$ AR on newegg and makes the 5770, gtx550, and the new 6790 just about worthless.

I would say this new card needs to be about 120$ to make it worth it.

6850's are generally only faster than stock gtx460 1 gig cards. But reality is that most gtx460's are not stock. Only 5 of the 27 listed on new egg run at stock speeds. 13 run at speeds => 750mhz (10 of which are in stock), which represents at least an 11% increase in core speed.

The majority of 6850's have creeped up to 165.00 and some offer rebates bringing them to 150.00.
Its a no win situation regards to 6790 launch price, which will probably be 150.00, when compared to 'old stock' prices, which benefit from many AIB's competing.

Is there an echo in here? You posted the same thing yesterday.

How about you provide proof that a HD5770 is worthless compared to a gtx460. Oh, you can't, because something that is worthless doesn't sell for $100.

LOW POWER CONSUMPTION HAS VALUE TO PEOPLE.

The above is a fact. It may not fit in with your world view, but it is a fact nonetheless.

Ok I owned a 5770 and now own a gtx460 and compared to the gtx460 the 5770 was worthless. There is your proof. Why? because the 5770 could not achieve above 30 fps in some of my games, so yes it was worthless.

And the lower power consumption didn't make it any faster.
