I wonder why the 4870 was beating the 4890 in 2 out of 3 settings in Dawn of War II :confused:

Anyway, seems like a very decent card, albeit not jawdropping. Fairly nice temperatures and power figures, at least.

Anyone have a DL link for this 'RC9' driver they were using?

These results are rather weird. The 4870 beats the 4890 at some settings, which simply isn't possible if they did the tests properly and repeated them a few times to compensate for variance

Yeah, it looks more like a quick user benchmark rather than a full review.

Ouch, the HD4850 with 512mb suffers a lot.

1gb seems to be the minimum nowadays.
And it would have been interesting to see how the same card with 1gb compares to the HD4870, but most likely it would have been a difference similar to that between HD4870 and HD4980...

Well folks, here you have it. HD 5770 and HD 5750 tested, stock and O/C.
Ah....and 2 x HD 5770 tested. And what do you know... 3 x HD 5770 tested.
All this in an epic battle, with HD 5870, HD 4890, GTX 260 and GTS 250 as
companions. And, for the extreme guys out there, a few words about
volt-modding the HD 5770 and the HD 5750 (and I mean volt-modding, not
that "software" ladies stuff :D)

The HD5770 numbers look a little disappointing, but I don't think people should've expected these cards to [edit out: really compete with] actually beat the HD4890.
They have the same number of SPs at 61% of the memory bandwidth. It very good performance for it's specs.
My personal opinion is that it's an awesome card, the only thing it needs changed is the target price. I think $130-140 MSRP would fit it much better.

RC9? Those aren't even available from the ATI site the reviewers get our drivers from. I don't even think they exist.

Usually an ATI driver will go for WHQL certification at the RC8 release from what I am told.

Gigabyte, HIS, Sapphire 5770 @ newegg now

anyone else thinks ATI missed a beat here with 5770? they could have had slam dunk "mainstream" card and they f'ed it up with their 128 bit bus. welll not very unlike the 5800 series which should have performed much better with wider bus

Really? Interesting. One way or another, I have never seen an RC8+ driver being made readily available for the launch of a card.

I think the price is too high. The HD5770 should be around $140 and the HD5750 around $120. It around the same performance as a HD4870 so the price should match it or be a little more. This card should be cheaper to make then a HD4870 too.

I think techpowerups review was quite good, it shows what to expect for performance. Looks like a decent overclocker, with very nice gains. Around 4870 512mb performance, but it really jumps up alot from clocking.

Yeah I love techpowerup! relative performance, performance/watt, and performance/dollar charts.

It seems the 5850 is the most efficient in terms of power and 4850 is most efficient in terms of price.

I hope they lower the price of this. DX11, or Eyefinity don't really do anything for me (yet)

Good objective reviews sky. I'm considering getting the 5750 if i can get my AC accelero on it. Thanks for doing a good job.

Here's another for the list.

ATI Radeon 5770 / 5750 şi CrossFireX 2x 5770 @ wasd (Google Translator required)

It looks like it hangs very well with a gtx260. This may be a good card to grab till we see what nvidia has to offer.

It would be nice to see mid range cards benchmarked on mid range platforms for a change where people can get a real world idea of the cards.
Who would want to put a $100 card on a $600+ CPU:down:, not inless people are getting payed to make the cards look their best. Cant you put your feet on the ground once in a while.

I :)

I think this is pretty good card and I'll buy it definitely. One or two, still don't know. It clocks very good, looking for some vmod:up:

It was posted before but I think you missed it:

ATI Radeon HD 5770 VMOD and ATI Radeon HD 5750 VMOD

Regards,
matose

so, 2x5770 >= 5870 in games ( except crysis)
and its cheaper.

^THIS^ I agree, sir.

[Start tinfoil hat mode]

It's just missing the optimal ratio, albeit not by very much, just enough to totally fubar it being a replacement for 4870/4890.

4770/4850/5850 all use a 64Gbps/1TF ratio, and with most games and AMD's arch that seems to work very well. Anything above that seems to be diminishing returns for the most part; anything below that seems to suffer an almost linear drop. 5770/5870 miss this by ~12%...

Neither the 5770 nor the 5870 can accomplish this, and I think they both suffer for it. Looking at the overclocking scores, once the mem is OC'ed to the proper level (1360/5440+) on the 5770, it seems like it fits right where it should, right below 4890, but quite a bit ahead of 4870.

Yep, they should've opted for 192/384-bit with 1920/960sp and 925-950mhz clocks imho, with the salvage parts using 4gbps GDDR5 to subsidize the need for 1.5gb, which a part like the 5750 wouldn't even need, eliminating the need for the two SKUs, since it's currently awkwardly placed. Of course that would fubar an X2 part down to only being a "5850x2", but who cares? It'd be the same in the end.

On the bright side of that could'a,would'a,should'a...I think that's a very real possibility for the 32nm refresh. Granted, it probably won't be 384-bit, but 256-bit with 7gbps GDDR5, with effectively the same bandwidth. Add 200M transistors to make it 1920sp/96tmu, should allow it to shrink down to ~rv770 size, and you're good to go...even for an X2 part...at the same amount of silicon as a 40nm Furbi, if it's out by then :)

Same thing could go for a Juniper refresh...at about RV740's size they could make a sweet replacement chip for the you-can-smell-it-coming $199 5830 that'll be 1.6TF (625mhz/1280sp).

I only complain and speculate for brighter days because...

[/tinfoil hat mode]

5770 is a major disappointment in it's current stock iteration and price.

i like the review, even though i could only read the charts, it looks like 2x 5770s can sometimes beat a 5870, but add on the 8xAA and they quickly lost 10% more FPS than the 5870 did.

They should be cheaper imo. In Canada, they are 179.99. A good price point would be 149.99 or 159.99...

I would grab one in the mean time waiting for Nvidia to release their monster but the price seems a bit steep for what it offers. a 4890 could be had for less and it outperforms it.

:yepp: That's probably why they're still in stock @ newegg.

ATI has strung together a bunch of winners recently. It was just a matter of time before they came out with a loser.

I for one too did, it was moronic for them to go back to 128bit for cost cutting reasons. LOOK AT THE DAMN COOLER ON THAT THING AND ITS GDDR5, thats where the cost cutting should have been!

The thing is running hotter than cypress 5850 if I am not mistaken too.

the heatsink is pretty cheap, no heatpipes, and only a ramsink on the memory.

the 128bit i think is just its limitation. (this card is very close to a 4770, but with good 40nm silicon to work with) when you look at benchmarks for 1680x1050 and lower resolutions, its not nearly as bad as 1920x1200+ or when you keep the AA low.

price wise, its on par with a 5780, since 2x of these costs about the same, and performs about the same. cause it really is just half of a 5870.

the problem is that ram has not increased much in the last 18 months, GPUs got 2x as strong, but the ram is only 30-40% faster

Yea, it is pretty cool to see Eyefinity, Dx11 and all those other features available for that low price but I find myself agreeing with many of the reviewers (and people in this thread) who are saying that these cards need to see a small price cut. They really haven't changed things around much in terms of what is the best deal and you still pay a premium for those new bits. I'm glad to see the length of the card coming in just under 9". I'm really hoping this becomes more standard after things got so long. Also saw the overclocking on the Asus card at hardware canucks was pretty awesome, 1GHz core mmmmm tasty.

Not always true.
Over here the prices are like this (cheapest ) :
5750 120
5770 165
5850 190
5870 280

so compared to the 5850 the price of the 57X0 cards is high. for 50% or 20% more you could get the 5850.
Its a nice card but it has to be cheaper.

you could get a set of 4850's for less than a 5770 for crying out loud.
And those are new cards i'm talking about.
120-140 for a second hand 4890
90-120 for a second hand 4870

and yes i know those dont support dx11, and yes they use more power but still.


i'd like to get me a 5750 or 5770, just for some oc fun :p: see if it can clock higher than my 1200mhz 3850 :rolleyes:

This card really doesn't make sense until the price comes down to about 110-125 US dollars and really doesn't perform on par until the ram is overclocked.

From what I read at Anandtech the Juniper team only had 6 months from the time Cypress was done to make the Juniper chip, given such a short time frame I would say it is a decent card.

I would guess if they had more time they would have made it a 192bit memory, 192bit probably would have been the sweet spot for that memory frequency.

where do you find a 5850 for 80$ under MSRP?

All I can Say is "WOW". The 5770 is not great(by itself), but crossfire it and ..wow! Somehow it's scaling is even better than the 4870's.

The 5770 XF is "usually" within about 5% of a 5870 throughout most all the tests. And even sometimes beating it!

I was mostly looking at the ComputerBase review.

Riddick AODA - 2560x1600 8xAA/16xAF:
5770 - 14.8 FPS
5770 XF - 35.7 FPS
141% Crossfire increase! What?!?!?!? :eek:


Anno 1440 - 2560x1600 8xAA/16xAF:
5770 - 23.2 FPS
5870 - 27.0 FPS
5770 XF - 45.6 FPS
69% increase over a 5870! ..and yet another 141% increase over a single 5770:p:

To copy the legendary R300King! post.

Ummm, fishy, lol.

Just sat here tonight breifly and gone through the numbers on guru3d's crossfire benchmarks for this card versus the HD 5870 and HD 5850. Now effectively the cards now are exactly half the cards there big brother are. Eg:

800 Shaders vs 1600 Shaders
40 TMUs vs 80 TMUs
16 ROPs vs 32 ROPS
64 ROPS(Stencil) vs 128 ROPS(Stencil)
128bit vs 256bit
GDDR5 vs GDDR5

so taking into account Crossfire isn't 100% performance increase, i don;t see how everyone can be going on about the HD5770 being memory bottlenecked by a large margin, and no one mentions it on the HD5870, which is double everything. On top of this viewpoint, take the average increase/decrease over all there tests, we get the following:

HD 5770 CF vs HD 5870 = 105.3892179%
HD 5770 CF vs HD 5870 = 123.9203387%

So two of them according to initial results are outdoing the single high end card on average, which in the UK costs more as well.

This was using the 1920x1080/1200 results they have shown on there graphs, and where i would be using them personally. I also have to point out i do believe it is memory starved, just not by a huge margin.

And in the performance above, what do you think is causing this. My main culprit would be efficiency in the HD 58xx 256-bit memory controller or PCI-e bandwidth or something else internal because if you look at some of these results. HD 4890 vs HD 5870, there a few areas that the new cards arn't a huge jump forward. Key ones being:

Texture filtering (memory is making a difference, but still a 28.5% increase)
Pixel Fillrate [64-bit FP/Blending-32-bit blending] (same thing. memory making the difference)

so yeah. I know it;s not the best examination, but from what i have read at look at there, with crossfire being good now days, HD 5770 CF for cheaper and just over HD 5870 performance anyone?

- Paul :up:

EDit1: Just adding this in for proof of the FPS and averages i took. If theres a error feel free to let me know!

US dollars? Kichroa? Where's that?

WTF. Just look at the triple Crossfire numbers from lab501.ro

http://lab501.ro/placi-video/ati-rad...-mainstream/12

Except for Crysis the performance almost triples in every resolution. For $480 it's only about $100 more expensive than the 5870 but miles faster.

Only, AFR in triple CF would suck twice harder than AFR in regular CF, which is INCREDIBLY BAD in the first place. I would guess the momentary FPS of a 3xCF system would be like 5 - 200 - 400 - 5 - 200 - 400 - 5... :D

What does this mean? Are the upper end 5800 series being held back by drivers? I am surprised nobody has looked further into the reasoning behind this.

Well technically 3 HD5770's are more powerful than one HD5870 but the unbelievable point is the near %100 scaling with each added gpu. 40-80-120.

I think so too. I think DAAMIT is just waiting for the Fermi so it can open teh can of WhoopAss! lol

If you look at what 2 5770's in crossfire can do..I think this is really what the 5870 can do if given it's full potential. Maybe more memory or bandwidth, don't know yet. ;)

CF 5770's look very nice. If they can come down in price to the 120-130$ range, ATI has a real winner.

Actually , take a look at those crossfire scailing numbers over at guru3d. It almost scales perfectlly double. It even beats out a 5870 fairly easily. 2 of 5770 ftw

This has to prove some kind of performance issues with 5870, way more potential in that gpu no doubt.

New driver for HD5800 and HD5700 series cards

http://support.amd.com/us/kbarticles...icsdriver.aspx

2 x HD5870 scale in Crossfire almost the same. But obviously, they are more CPU limited then 2 x HD5770.

No thats euro's
so in dollars thats
178,38 for a 5750
245,26 for a 5770
282,42 for a 5850
416,19 for a 5870

Yes, with these cards we came to the point that 2 Junipers in CF can be faster than 2 Junipers on one die (Cypress). The problem is set-up rate (triangle rate) which not doubled from 1tri/clock since very long time ago. So 850MHz Juniper has the same set-up speed as 850MHz Cypress. Take 2 Junipers in CF and you can get up to 2x850 million triangles per second.
Next gen cards should solve that bottleneck.

Those 5770CF figures again point that there's something horribly WRONG in Cypress.

EDIT: whats up with anandtechs 5770 review btw?
they seem to have the slowest 5770 results of any review ive read so far? :confused:
everybody else has a 4870 and 5770 tied and for them the 5770 was notably behind in almost all tests?
they edited their review several times cause they had several numbers wrong... sounds like they really need to check their test rig and re-run everything...

About dual HD5770 throwing higher framerates than HD5870, can't it be simply that the resources are being better used when rendering 2 different frames than when rendering only 1 frame?

I have not thought about it deeply, but we should take into consideration that these different configurations are doing different things.

Maybe as 5770 has half the operational resources than 5870, in the rendering of every single frame there are points where 5870 leaves more resources without being used because at some points both may have enough, or 770 being fully used but 870 having more than necesary. As the second 5770 doesn't add its resources to the first one (wasting them when not needed), but renders another different frame, it may end up doing a more efficient use of its resources.

I have always thought that the problem of AFR is not its potential framerate scaling, but the irregularity of that frames output, the dependency on the CPU rendering times, compatibility issues, and so...

is there anything lower then 5750 ?

Not until Q1 2010

triple cf usualy sucks in games, but the scaling on the 5770 looks pretty sweet. Do you think price/performance 2x5850 is better than 3x5770?

yepp,
but 3 5870s is where it is @ but 3dm only counts to me

yeah it is called nvidia...lolz

jk...for real, fanboys are :banana::banana::banana:gs

id like 2 5750s in cf for my htpc

hm, this just struck me.

3x5770 will cost about $600 USD in Denmark. These will beat a single $500 USD 5870 by far. BUT, the 5970 (or 5870X2) will probably only cost about $600 USD, and this would definitely beat 3x5770, or am I wrong?
