Hey that's funny, they claim it has 24 rops, yet it has only half the memory controllers of the HD 5870, and the rops are tied to the memory controller. The HD 5870 has 32 rops, so how does a HD 5770 end up with 24 rops?

Now wait-a-minute, it has 4400MHz GDDR5, with a 128bit memory bus, how in the hell do they get to 76,8GB/s ?

I'd say it's either a fake review, a shitty one, or both?

well i said this in the other thread but the card performs just like most people expected which is more or less with the 4870. 56tmu and 24rop seem illogical for 800sp and 128bit bus. seems like it should be 40tmu and 16rop.


"Perhaps we were expecting too much, but the Radeon HD 5770 was a little underwhelming in our books. Where performance is concerned, we expected it to be positioned in between the Radeon HD 4890 and HD 4870, but our tests have shown that it was mostly a smidge lower than the HD 4870 1GB editions; which puts it closer to the 512MB edition of the Radeon HD 4870."

"The results seem to indicate the shortcoming of the 128-bit memory bus that the 'mainstream' Radeon HD 5770 possesses."

yeah the rop and tmu numbers dont make sense. the memory is supposed to be 4800 though so that is 76.8gb/s.

I'm not impressed nor dissapointed by it's performance. I was hoping for more, but considering the price and the stuff you get, it's a great deal. That's all I can say for now... 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 ...

The idle power consumption figures jump out at me the most.

60 watts better than HD4870 1 GB.....at idle?

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

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

For a $159 card it doesn't really impress in the performance department does it?.....Well at least not compared to the value offered by $259 HD5850.

But for a new buyer looking for a mainstream card I think HD5770 would be a much better decision than HD4870 1GB....heck the energy cost differences alone easily justify any discrepancy in initial purchase price.

Something tells me OC versions of HD5750 will be more popular.

 

[Allio]

Performs more like a 4790. The 4770 was nipping at the 4850's heels, while the 5850 is in another ballpark entirely to the 5770.

Still, that energy consumption and the temperatures are amazing. I'm hoping they'll be so cheap to manufacture that prices will drop rapidly, which will make it an amazing deal.

 

[MagickMan]

Seems like it would be HTPC card to get, given temps and wattage.

 

[nyker96]

thanks for the article, reading now ... the card is just unimpressive to say the least, I'd just get a 4870 with a rebate for much lower than 150.

 

[bunnyfubbles]

too many mistakes (simple ones at that) in the numbers for me to take this article too seriously

They even claim the memory is 7Gbps...which should mean the memory could be clocked to deliver 110+GB/sec and thus better equate to a 4870/4890 in raw spec

 

[crisium]

So there's no DX11 card to replace the 4890 yet. I wonder why? If your budget is $200 you are stuck in a hard place. $60 more gets you lower power consumption and higher performance + DX11, but in the short term you might not be able to go that high. $40 less gets you inferior performance, but waaay better power and DX11. But if you want the outright better performance, you would simply not consider this.

Settling with the 4890 gradually saps away more money from the power consumption and doesn't have DX11. Maybe ATi is trying to unload as many 4890s as they can before they release a 5790 / 5830?

For most people who are not graphics whores or game at godly resolutions than the 5770 is a good performer though. Let's not bad mouth it too much. My Radeon 4850 rocks the house pretty well for me, and this is faster. This would be decent for 1680x1050 performance. But I wouldn't upgrade to it from anything faster than an 8800GTS (G80) or 3870. Say... an 8800GT to this would be an improvement without question, but maybe not as good as to be worth it.

What kind of review is this? No mainstream resolutions (all the resolutions rested are 4:3! Who plays on a 4:3 monitor nowadays), and only three games? Very disappointing.

that site always has the worse reviews and they make plenty of mistakes.

Shouldn't the Anandtech HD5770 review be up in 4 1/2 hours?

well thats when nda lifts so probably.

That site sucks.

Still that review shows enough to suggest it's not the card for me. I want near 4890 performance. Not near 4870 performance.

Guess I'll have to dig deep for a 5850.

 

[Rezist]

I was really, really looking forward to this card. This performance is just too low however. I fully expected it to outclass the 4870 until 1900x1200 in which the bandwidth limitation would show up.

That being said if the 5750 performs only slightly worse it could be a great card for the price. Not to mention the power savings and the cheaper PSU you could run as well.

Every preview I've read puts the 5770 between the 4870 and the 4890. Brent Justice alluded that the 128-bit memory bus wouldn't affect the performance of the 5770 at higher resolutions, while everyone else was doubting - but this guy actually had the card in hand, but couldn't say more because of the NDA. I'll wait until the official NDA is up until I make any decisions.

FWIW I'm almost positive I'll jump on the early bandwagon and snag one at $160.

If I were some I would look hard at 2 of these cards with A M/B that has Hydra chip/

Low cost great performance .

well, it really sucks, i was expecting the same though... all I thought was it was a notch lower than the 4890 in performance but what the hell! it appeared to be just a 4870 512mb in performance...

I'll wait for the 5770 anandtech review and see if the numbers add up

a 4870 is a notch lower than 4890. at your 1440x900 res the 512mb or 1gb on a 4870 would be irrelevant.

 

[MODEL3]

This review doesn't make sense.

I 'll wait for AT review.

I 'll stick with my prediction about close or a little bit higher (+5%) than 4870 1GB average performance (-10% up to +15%) depending on the game/resolution/quality settings/ AA & AF options.
