In the Guru3d review the HD5770 does just as well as the HD4870 in Crysis.

But in the Anandtech review, HD4850 beats HD5770 in the same game.

Yeah, there does seem to be a strange discrepancy between the 5770 reviews. TPU got an insane memory overclock on their sample (1500mhz), while the other two couldn't break 1000mhz. They also got a much more relatively louder sample than Anandtech did. I wonder what's up.

Well if DX11 delivers and the devs adopt it, future games should rely less on bandwidth and more on the engine, so maybe then these 5770 (which seem to OC quite good) and the 5750 will perform better.

Another reason for this higher price might be AMD/ATI wanting to get rid of the 4xxx series and then drop the price on the 57xx.

getting rid of the 4xxx series is certainly one of the reasons the prices are where they are.

I just noticed techpowerup used a HD4870 512MB for comparison...not the 1GB model.

I would be careful with high memory overclocks. If the AT 5870 article is right, the memory bus isn't error-free too far beyond stock, which means they may actually be hurting their performance if the card is constantly retransmitting to correct errors.

Crap performance for the price

From my own review I can say the HD 5770 = GTX 260 for the most part (they are REALLY close) but the HD 5770 is most definitely slower then a HD 4890. Not really strange, considering they have the same amount of stream processors clocked at 850MHz, yet the HD 4890 has 1.5 times more memory bandwith. When the HD 4890 dissapears, there will be a huge gap between the HD 5770 and the HD 5850, so I wonder what AMD will do about that ...

As for overclocking, I reached a sound 1000MHz/1250MHz using 1.3V. That was basicaly the only thing I had time to test, but I bet it can go even higher or that it can do 1000MHz with less volts.

 

[BFG10K]

Somewhat disappointing performance, but I?m still keen to test it. I think I can paint a more interesting picture than mainstream reviews because I test more games.

 

[Dribble]

This card is in some ways a bit of an answer to all those Ati fanboys out for nvidia's blood.

I bet it could have been released significantly cheaper but because nvidia isn't releasing a new cheaper card to compete right now Ati are milking it for all they are worth.

I would like to see something that no website will likely do. on paper the only difference between the 4890 and 5770 is the memory bandwidth. I would like to see the memory lowered to 2400ghz for the 4890 to match the 4800ghz memory speeds on the 5770 and see if the cards run basically identical.

 

[nemesismk2]

I expected 4870 performance from the 5770 and that level of performance is what it's giving. The 5770 is just about the price of a 1GB 4870 as well.

even if there was no competition from another company, the 5700s priced any lower would undercut the plethora of 4800s still in stock, AMD isn't going to out-compete themselves, of course they're going to milk it until those 4800s can be cleared out

 

[nOOky]

I am somewhat disappointed in the 5770's performance also. I was thinking of replacing my 4870 with two of them in crossfire, or going with a 5870. I have been waiting to see if I should get two 5770's, maybe add another 4870, or go with a 5870. It's looking better for the single 5870 right now...

 

[Dari]

As someone else mentioned, perhaps this is ATI's way of moving old hardware (perhaps) before dropping prices?

 

[Rhezuss]

Ok so, after reading you guys, if I want to replace my 9600GT 512mb, the 5770 512mb would be a great choice?

But after looking at the 4850 512mb performances compared to this new 5770, i'm leaning towards the former...

 

[yacoub]

Just read the anandtech review... oh well, so much for this card being worthwhile.
Great review, pathetic card.

I wonder if AMD has something for in between the 5770 and the 5850 though, because there's one hell of a gap that needs filling ...

yeah based on how the 5770 looks I see 5830 coming very soon.

yea I see a 200$ 5830 in my future.:thumbsup:

And it better have similar power consumption with 5770 and it's in my future as well. I was a little disappointed in the performance of the 5770 (what's with Crysis?) so I hope there's something to fill the gap and make 5830 or whatever the clear choice. Or I'll just wait for the 6000 series. Not like I need more frames in Quake Live

Same with the 5800 series...

4870 was $299 at launch, 5870 $379
4850 was $199, 5850 $259
4770 was $110, 5770 $159

I know I'm not upgrading until Nvidia releases their card and the prices are normalized. The $199 5850 was the one I was planning to buy.

Only problem is 4870 1GB costs $136 vs. $159 for 5770 and it actually performs about 10% faster.

The days of a midrange card wiping out the top end card (i.e., 6600GT wiping the floor with 9800 XT) will have to wait for another generation.

 

[bunnyfubbles]

Has anyone taken a closer look at the CrossFire results? According the AT review, crossfired 5770s are almost always just as fast if not faster than a 5870. Just about every game except Dawn of War II (and to a lesser extent, Crysis) dual 5770s actually seem like a better deal than a 5870, especially when the idle and load power numbers are also so very close. I find this strange considering the 5770 is virtually half of a 5870, and would have assumed scaling inefficiencies to keep dual 5770s consistently below that of a 5870. That being said, I think that might be indicative of room for improvement via drivers...that or a potential 5770 X2 would be a very enticing proposition (assuming such a product would be priced around $300)...

Err, I don't remember the 6600gt wiping the floor with a 9800XT. They were about equal, and traded off in games. Remember, the 6600gt had a paltry memory bandwidth. (there was also a 2 year gap between the card generations)

The most impressive thing to me in Anand's review was how well crossfire scaled with most games. Seems like crossfire is finally maturing, I don't know if Lucid's Hydra is going to have much of a market when Crossfire already has near perfect scaling in most games and comes practically for free.

Is 5770 CF a viable alternative to the 5850 for those with dual-pci-e boards?


Even if it the slightly more expensive option

Could lead to a PSU upgrade costing more money.

 

[JimmiG]

Yeah the crossfire scaling is actually pretty good. Maybe my new upgrade plan should be to buy one 5770 now and then add a second when prices come down..that way I can get a 5870 for maybe $240

they use a similar amount of power less than a gtx275 actually, about the same as a single 4870

If prices fall to about the level of the 4870 1gb then i think crossfire will be a very good option

 

[Vertibird]

Does Nvidia plan on doing a "die shrink" of 285 GTX?

Because something like that could be real competition for HD5770 if it only needed a single power connector. (even if it didn't have DX11)
