Yes on Ati , asynchron at nvidia cards and oc'ing shaders brought improvements on nvidia side this is why i asked how it would effect test.

what difference would this make?Since shader clocks run at the same speed as the core?

Well theres no way u can measure the increased performance of just the shaders on ATI cards...
U cant OC them alone as u said,only together with the core.

Pretty good overall. Not that far from my 4890. I really like those power consumption results.

Sure enough, those memory modules would need some better cooling. Heatsinks on one side only.

I'm curious about the memory temps. They should be a lot higher than the GPU itself. but CCC don't tell you that.

 

[ArmoredCavalry]

You think my friend's 430W antec earthwatts psu would work for this?

 

[Bl4ck]

low power draw = good
price = wrong
DX11 titles are very far away, just like transition from DX9 to DX10 reviewers will have to test these cards in DX11 titles ;]

Nice card and review. IMO people who have 4850/4770 will still stick to their cards and the people who are going to get new rigs, would look into this definitely.I fully agree with w1zz on the price point and what others say on the Best $200 card, as I always bought a card in $200 range and OCed it.

+1 for the mem OC too.

very nice as always
Now i must get myself a 5850

many laptops are still 1024x768. Also all the netbooks and UMPC devices have small screens too. Having a hi-res click link is probably better. The nasty part of the internet aiming at the least common denominator.

I love how smart you are...

--
I may just have to get 2x HD5770s. They are the only cards short enough to fit in my case it seems.
@Cavalry- Yes.
@zCexVe- I am going to get an HD5770 because it still beats my HD4850 in all areas.

Hmm, where are you finding laptops that are still 1024x768?

Maybe 1280x768, in a 14-15"

Onto this card--

Looks pretty amazing... I hope Nvidia has something up their sleeve... This is a hardcore pwn fest right now.

 

[Benetanegia]

if those cards really were memory starved then wouldnt reducing the core clock result in no performance decrease at all?

I think you're right. Reducing the core would have little effect on performance because the core is waiting on data from the memory. (assuming they are in fact memory bottlenecked)

However, has this been tested? (Did I miss something)

Anyway, you don't contradict Benetanegia. Both of what you say can be true. It's just that W1zzard's test would be a conclusive test. (Can we get a quick test?)

I would love to see some benchmarks, I love those kind of comarisons, they tell much more about GPU architctures and graphics workload than anything else. And yeah, I suggested exactly that procedure in the HD5xxx discussion thread to see if the HD5870 was memory bottlenecked, Zubasa even did some tests that "proved" that it's not. For the record, I have always defended that the HD5870 is not bottlenecked, but I do think this one might be, I'm not sure 100% but chances are high IMHO. That's the simpler explanation for the performance gap between HD5770 and HD4890 and I have always been a fan of Occam's Razor.

 

[MKmods]

I hope Nvidia gets going on their next gen stuff.

This 5770 looks like its gonna be spectacular if/when the price drops to the $100/110 range.

 

[HTC]

Someone please correct me if i'm wrong but, as far as i know, there aren't official drivers for 5xx0 cards. If so, it stands to reason that performance should increase once such drivers are released and thus shrink / eliminate gaps between this card and 48x0 cards.

 

[Steevo]

as the page says: stock fan and voltage settings

not sure about dx11 yet .. how would i compare nv dx10 w/ ati dx 10.1 w/ ati dx 11 ?

Formulate a DX11 improvement/penalty bias based on ATI/NV cards that are capable. The new 10.1 NV cards suck donkey balls, but at least it is a starting point.

So Dirt 2 in DX10 5850 XXX FPS, DX 10.1 (if applicable) XXX FPS, DX11 XXX FPS.
On NV Hardware DX10 XXX FPS, DX 10.1 (if applicable) XXX FPS, assumed DX11 XXX FPS witha very restrictive trend line. Perhaps it might encourage NV to get you some hardware or performance numbers.

Do it enough and establish a trend. When NV gets their shit together they can join the party with accurate numbers.

 

[Sasqui]

WOW... the price/perf ratio is good, the power consumption is in line with all other 5xxx cards, which is superb, OC which is great, but "your mileage will vary".

Given that, the power consumption should raise it to 9.3, IMO. Kudos to ATI for finally figuring it out after the 48xx power draw-f*ck.

As usual, what great, consistent and level review.

 

[Mussels]

seems like a perfect replacement for the 4870

 

[wolf]

I like how perfectly they cut their 5870's in half

 

[Lazzer408]

Does it come in a single slot?

 

[pantherx12]

Not yet I imagine, but I'm sure coolers will come out or coolers that are already out will fit.

In the UK there's only a 10 pound average price difference between this and HD4870s.(based on google shopping search results)

Waiting to be paid,but not knowing if it will be this week or the other,i was tempted to buy 1 5770 for 169 euros and later on another one for crosssfirex action.
Would that be good or would it be wiser to wait some more and get a 5850???

5770's are performance equivalent to 4870's, so you can always check reviews of a 4870x2 for the relevant performance.

I'd say wait for a 5850. It's the 3rd digit of the ATI number scheme that makes the largest difference. For example. A 3850 will walk circles around a 4450 or 4650.

3850 example.

3 = Generation
8 = Family (higher = faster)
50 = Variant (memory type/speed/bit-width ect. Higher = faster)

The Variant could be ddr3 instead of ddr5 or something to that extent.

Thanks for the advise but after having corssfire 4850s i know that scaling is an issue...Sometimes u get 80% sometimes 20!

5=generation is the same
8-7=family HUGE difference cos of ROPs!!!!+256 bit vs 128 + almost half shaders...
70 vs 50 well nothing to mention here...

So even @100%scaling u wont get 5850 performance,let alone the OC of the 5850...
5770 OC well too,especially memory but i think i ll wait a little and get a 5850 and dcember i get a second one

 

[a_ump]

i really hope that official drivers improve performance a good bit. i was hoping that the HD 5770 would be better than the HD 4870, even with similar specs i would have thought ATI would have revised and improved their shaders. but i guess not . If this performance is what they truly can do, HD 5770 is a fail currently as its 149 yet the HD 4870 can be had for 129.

 

[pantherx12]

Remember its also smaller, uses less power, creates less heat and is Direct x 11 + improved HD audio.

Your paying for more then just the processing power.

 

[Ghiltanas]

These cards have 1GB too, so that's more like apples to apples. In Wizzard's charts the 5770 isn't faster than 4870 512 MB either (except at 2560x1600). Anyway, the specs of the card, sans the memory bandwidth, should make this card as fast as the 4890 and not the 4870.

It's memory bandwidth limited. The fact that the OC benchmark show a greater performance gain (11,4%) than the core OC (9%) also suggest the bottleneck. Look at any other review, the performance gain usually never gets close to the OC.

infact...ati made a clear lineup with 5000s cards. 58** bus at 256 bit, 57** or less 128 bit, so also using hypothetical gddr5 at 7ghz 5770 stay under 4890 ...The 4890 replacement probably would be a 5830 withbus a 256bit, but 1280 sp (160*8)
