AMD Radeon HD 7770 And 7750 Review: Familiar Speed, Less Power

DX11, where GCN would put up its best performance.

Would it be possible to add a HD 4XXX -gen cards to the mix with the kepler reviews, there are still many of us with older cards looking to upgrade, but not quite sure how our cards match up. How much of an upgrade is a 7770 over a 4870?

 

[Achoo22]

This card is an absolute joke. Right now, a 6850 costs about $139, and this card needs to be costing /significantly/ less, not $20 more. It costs /much/ less to produce and it performs worse - I'm very much offended that they offer this garbage up to us at $160. What kind of fools do they think we are?

Maybe AMD is intentionally selling these at an inflated price. Hear me out on this. Maybe they have the high prices to drive people into buying the old inventory of 5xxx and 6xxx cards. Then once that is cleared out they'll drop the price. Either way they make money, whether they sell a 7770 or a 5770. That way inventory on old cards sells quick and you are left with simply making and selling your current gen. Just a thought.

I bet that OEMs will make radeon 7770 w/o additional power connectors. It's a shame though that new radeon X770 isn't best value card anymore...

this might be true, because in many stores I still have countless 6xxx and 5xxx, after those will be out or almost out we might see price drop. + why not to milk crowd while can?

[citation][nom]dragonsqrrl[/nom]"Although other cards beat it in encryption and decryption performance, the Radeon HD 7750 easily secures a second-place finish in the SHA256 hashing test."I think you mean AES256.[/citation]
Not sure why I'm getting thumbed down, that statement in the article is clearly a mistake according to the corresponding graph. Or do you guys not understand what I'm referring to?

In the Sandra 2012 Cryptographic Bandwidth bench, the 7750 performs second in Encryption/Decryption (AES256 GB/s), not Hashing (SHA256 GB/s).

[citation][nom]MattMock[/nom]In the monthly best Graphics cards you mention that AMD is dominating. I wonder why though. Are Nvidia's cards capable of maintaining a price premium because consumers are willing to pay a little more to use Nvidia drivers and extras like PhysX and 3d vision? Or possibly are their cards more expensive to manufacture and so Nvidia must raise prices to maintain margins and simply suffer reduced sales at those prices. Anyone know?[/citation]

you know, when nvidia 3d came out, i was ready to spend a grand on upgrades so i could play games in 3d, i have done it in the past with a head mount display, my god... was the best game play experience of my life.

ready to buy, till i read the system requirements.
windows vista only.

you have no idea how high up my hopes were, a supported product that i dont need to dick around with 3rd party drivers, and the games are already out and every game works... and than the biggest kick to the balls i have ever received.

i tend to think nvidia people a complete douchebags. that is the 1 and only reason i will never return to the nvidia platform again.

----------------

for me if the 7770 had 1.5 or 2gb of ram, i would buy it right now, as i have a use.

i also have a use for tessellation, and i love that these cards preform great with it, but i need more ram on the card, i dont want problems when i go 100% on testure sizes, the only thing in most games that matters to me anymore.

It's not hard to see why the desktop folk aren't impressed, but I will kill to have this new 7770 in my notebook as an upgrade to my 6770M.

I know this particular card burns twice as much power and couldn't just be 'drop-in' replacement for Turks in a 120W system, but considering the strong efficiency improvements over the last generation; I think it's at least possible.

Perhaps it'll happen in time for my next hardware refresh.
Then again, it'll almost certainly make its way to higher wattage, 'gaming' notebooks, for those who can afford it

AMD, the "consumer's friend", releases their Bulldozer of GPU's. LOL

Overclocking?

Nope, you're right. Those light and dark red bars through me off there. Typo fixed! Thanks dragonsqrrl.

The HD6670 needed to be on those charts! I want to see how much better the HD7750 is. With a price only a little above that of the GDDR5 version of the HD6670, the HD7750 looks like an absolute killer for a budget card.

 

[DSpider]

I would like to see a passively cooled HD 7750.

Dead-silent HTPC with 5770 performance (a card good enough for 1080p gaming, perhaps even with mild AA).

Yes, please!

Anand benchmarked it against Crysis Warhead and there's a HD 4870 in there. The HD 7750 performed similarly to your card (as did the HD 5770) @ 1680x1050.

HD 7770 performed much worse than the HD 6850. The GCN architecture seems to shine more in DirectX 11 titles. Give it some time for the drivers to catch up. Because right now you just can't compare them (fairly) with DirectX 10 cards.

 

[neiroatopelcc]

I wonder what the performance of the 7750 card would be in applications like autodesk inventor ? maybe it'd be a good alternative to the quadro 600 which also shines only on the one factor that it fits the wattage evenlope of a cheap business pc.

 

[kikireeki]

A boring card.

 

[mchuf]

[citation][nom]Derbixrace[/nom]the 7750 will be a GREAT card compared to the 6670 for those who have a shitty 300w PSU and wants a nice GPU.[/citation]
NVidia can't even compete with AMD's HD6670 and now the HD7750 is released? I don't understand why NVidia has completely givin up on the market for HTPC gpus that can be used to play games at a decent level. AMD has this niche locked up and as a result, prices in this segment are higher than they should be. Looks like this summer I'll be replacing the HD5670 in my HTPC with a HD7750. NVdia just lost another sale.

 

[nutmanmatt]

Well looks like i made a good choice picking up a gtx 460 1g for $120 was looking at the 7770 before but it looks like a fail at that price.

 

[maxinexus]

I think that they made a typo and priced them closer to much better 6850 and 6870. These should be AMD HD 7650 and HD 7670. Why would we settle for less and pay more? Who in the heck is doing marketing in AMD?

 

[lradunovic77]

As I said before AMD GCN scaling is terrible. Another crap release by AMD.

 

[zooted]

If the 7770 was priced at the 6770/5770 level (which it will soon enough) these are actually pretty good cards. The 7750 needs to be at 70-80$.

 

[-Fran-]

When are you doing the XFire follow up, Mr. Chris? I have good expectations of the GCN scaling on the 7770 and 7750.

And the 7750 really stands out in there... That card in a notebook and inside an HTPC will be king for a lot of time.

Cheers!

This is just sad.
