HD5770 & HD5750 reviews

[Heinz68]

We've actually got three up:

XFX HD 5770 1GB GDDR5 Review

ASUS Radeon HD 5770 Voltage Tweak Edition Review

XFX HD 5750 1GB Review

Thanks.

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, 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

[matose]

It was posted before but I think you missed it:

ATI Radeon HD 5770 VMOD and ATI Radeon HD 5750 VMOD

[netkas]

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

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

^THIS^ I agree, sir.

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...

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

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 )

ATI Radeon HD5770 & HD5750 - DirectX 11 for the masses @ lab501
(Google Translator required)

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.

[Excessiveplayer]

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.

[xenolith]

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

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 see if it can clock higher than my 1200mhz 3850

[Stukov]

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?

[Your_Boss]

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?!?!?!?


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

To copy the legendary R300King! post.

[zalbard]

Ummm, fishy, lol.

[SpikeP]

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?

[annihilat0r]

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...

[96redformula]

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.
