The 5850 is a much more impressive card than the 5870 for price/performance. This is a card I can see NV having no counter for unless they price the gtx 285 just a couple hairs over 200 dollars. But they will take a certainly take a loss and the partners wont be happy.
I'm surprised people are not surprised by the insane performance / watt the 5870 and 5850 are offering.
The 5850 looks even more underwhelming (performace/specs) wise than the 5870. Notice how the 4890 actually beats it in Hawx in the TR review, despite having worse specs in every regard. The 5870 results looked like they might have been the caused by poor scaling, but the 5850 results make it look like something is broken. I'm going to chalk it up to drivers at this time, because I can't fathom how the RV870 architecture could have become less efficient than RV770 in terms of gaming performance.
Anyone else get the feeling that ATI might just release a 'miracle driver' at the same time as the GT300 launch?
Its at low res, only, and in one game only, and the card is just released.
The crossfire scaling looks great, it edges out the 285 sli in almost every situation, so the price performance for me, seems to be there, along with the fact through driver maturation the performance will go up a bit. Just waiting on some non reference versions to come along, to allow for better oc'ing, might be just in time to take a gander at how gt300 performance will stack up.. but by christmas , you ll probably see a 250$ 5850, and if the X2 scales like the 4870x2 (near perfect when compared to 4870's in xfire) the price perf will be a nice little gift to myself ^^
The point is that the 4890 should never be faster, and if you were to scale up a 4890 to the 5850's specs, it's looking like it would be faster than even the current 5870. Perfmance/watt is great, sure, but the performance just doesn't match the specs. Either the engineers totally screwed things up via an obscure bottleneck that makes the chip slower per SP/TMU/ROP than RV770, or the current drivers really suck. The second possibility sounds far more likely, and that's what I'm hoping for since I have a 5870 ;)
Anand's review shows that 5850 CF isn't scaling as well as SLI. So I think 5850 CF isn't a great option.
:confused:

5850 crossfire same price as the GTX295 and 40% faster too

edit: just realized 5850 Crossfire beats gtx285 sli on every bench at THG too. I don't get what you're saying.
Actually I believe Hardware Canucks was the first to do a review. But thanks for the update! It doesn't seem like the 5870 preforms as well as expected.
The 5850 looks like a great bang-for-the-buck card! Crossfire scales well too... Good stuff coming from ATI! :up:
Can't wait to see what Nvidia has to offer in turn... ;)
Up to 80watts lower consumption in load
120$ less
Quieter
Cooler
Shorter
Performance hit around 10-15% against 5870 (that means far better perf/watt and perf/$)
~12% More performance than GT285
Overclocks to 5870 perf easily
Ok, this is an absolute killer for the lower performance market segment. Its 4870vs4850 all over again. Only this time, they get the performance crown for single cards too.
Another thing to remember, is that nvidia does not currently have a countermeasure for this card. The GT380 will be priced for the enthusiast segment, and we can only hope for the architecture to be flexible enough to provide a 360 for the upper performance segment without killing profits due to diesize constraints. Things will get even more messy as soon as Juniper lands, the greens have to act now (thats our interest as consumers too)! And I don't think that GT200 respins will cut it.
Heavily matured G200 drivers vs brand new crossfire drivers.
Hmmmm... I wonder if one will improve and one will stay roughly the same... :shrug:
Well if you look at the long green bar in the graphs I posted, you can see that "5 percent" scaling like 50 percent.
:)
Looks like the 5850 wins in both single and CF results. Better CF drivers will only improve on this. No different then the 4800 release. :up:
Very impressive cards there, the 58x0s !!! Has somebody already tried LN2 ? SOme results ?

5850 CF can even run Crysis at 2560x1600!
From the Anandtech article, what is this all about? :shrug:
That conflicts with basically every other review I have read.Quote:
The 5870 ended up being hot, noisy, and more power-hungry than any other single-GPU setup.
AT seems to have gone off the deep end on video card reviews lately
Hell they put the 9800GX2 as being faster than the GTX280 initially and we all know how that turned out :rofl:
Quite impressive. I would have to say if you plan on buying 2 cards at once and only have a 1920x1080/1200 display that 5850s in CF are the way to go. I'd only seriously consider CF 5870s currently if using a 2560x1600 display ( or Eyefinity if that interests you )
There is enough of a cpu bottleneck (that is it! throw out the Core i7s! :p:) with CF 5870s at 1920x1200 that 5850s don't seem to trail much.
Here in Canada, its basically 30% more price for a 10-15% performance increase for single card (5850-5870) which often is the case with the highend ( 260/280 was even worse at launch ) I would have ordered a 5850 but I want to tough it out single card as long as I can as I had my share of multi gpu facepalms over the last 3 years to turn me off of the idea again, but I know ill eat my words eventually :rolleyes:
Should be good news for folks with single 285s that might want to go SLI soon as Nvidia will have to reduce 285 prices at this point ( provided ATIs new stock distribution method works ; eg weekly small shipments vs burst large volume shipments )
doubting it but anyone know if they are going to put out a 5850x2?
Too bad no review has tried to unlock the 2 missing SIMD arrays from 5850 yet, it would be awsome if it can be done.
I'm not impressed. By the whole R8-series, that is. Undoubtedly future drivers will increase performance but one cannot expect miracles that would be required...
I guess the architecture just doesn't scale properly over R7-series.
:(
Not so sure about that... Looks as if the regular 5850 doesn't have the necessary chip (VT1165MF) to allow voltage-tuning via software. The one made by ASUS might be the only 5850 to support that.
What where you expecting? A perf-increase of 100 percent? :shrug: I think RV870 is decent, but not groundshaking. Just what AMD has been telling for a couple of months... But yes, the next series should have a new architecture, it looks like this one has reached its border.
Has anyone found frontside pics of 5850 with cooler removed?
Btw, Guru3D has a pic of a "Radeon HD 5850 GPU wafer" on the bottom of one page in their review. In reality, it's a Deneb wafer.
:rolleyes:
I still wonder why the 5870 needs to be that long, guess its only a matter of the cooling sollution.
Great scaling
but i wana see one with a 4.2ghz oc or even more to see how fast theses cards really are.
well to be fair he did only goto 820 on the core, and supposedly the memory is .4ns 5gbps saumsung anyway, so going from 4000 to 5000mhz only puts it at stock. If there is/isn't a volterra, then it probably didn't matter as it's likely hilbert didn't need extra voltage for what he did.
If he had it at 950/1250+, then he probably needed voltage.
the simd unlock it's coming....
http://forums.anandtech.com/messagev...&enterthread=y
yeh in theory it should overclock to same level as its big brother as its the same gpu i think on the 5850 the stock voltage is slightly lower than on the 5870 thats why it tops out at 800ish on stock volts but once the the volt altering software is available it should be a different story
So what suffered going from 5870? Cooling or pwm? The card's much smaller.
They do overclock nice:

I don't see a review doing a hardmod to a card for a review. So, 99% sure this is software level. Not even sure if he had to increase voltage.
I doubt it, the 5870 only uses 18w more than the 5850 and some of that is going to be from the extra length of the PCB, so there can't be that much more heat emitted to add another two inches to the card, although you could cancel the heat theory out since on the 5850 the exhaust or intake vents on the top of the card are blocked by the PCIe power connectors, a cable and a capacitor, which would have some effect on the cooling.

Take a look in the review of PCGH

http://www.pcgameshardware.com/scree...5850-PCB07.jpg
I didn't mean overclocking, I meant overvolting :D
it looks like they should have flipped the heatsink so the heatpipes would be at the base, since the vents are up top. i wonder how much that can affect airflow
Wow, thanks fischoderaal!

AMD lowered 5850 TDP to 151w on final design.
Interesting, 3 gpu phases.
3+1 for GPU, option for 4+1. 1+1 for memory.
All Volterra & GPU vDDC & vDDCI are softmodable.
This is just a link to a thread where a user with 40 posts has said "I have done it, stay tuned and I'll tell you how"... followed by a bunch of posts that say "hoax". Hardly proof, but it's true... oh man. Buy now and in quantity before ATI starts laser cutting.
I will pass this card until price drops to 199 and lower...cmon nvidia :s
Since it seems a few people liked the chart I posted last time (SEE QUOTE BELOW), I figured I'd update it and post it again:
Updated sheet: http://spreadsheets.google.com/pub?key=pMt...amp;output=html
The 5850 is a better deal (from a strictly price/performance perspective) than the 5870 by a decent margin but still doesn't change the fact that the ATI 4870 (1GB) and the Nvidia GTX260 (216) are the best deals on their respective sides.
If this card was a knockout it would probably be $600 so it seems fine to me.
I know what you mean lol, and if I had tons of time on my hands I probably would for the sheer fun of it (yes, slight masochist) but I just don't have that kind of time these days :(
Yea, I put in the "from a strictly...", because I know features has it's own value (and it is often a bit more subjective value).
HOw does it fold? still like crap? or did they change that?
-Levi
its still crap, but hopefully very soon it will change

Looks like 5870 has no advantage over 5850 on 24' monitor. and 4890 OC'd/5850 are so close @ 1680x1050.

Just to clarify, which areas, other than the RAM, will need cooling if I go for a GPU only waterblock? I don't plan on buying a new one especially for the card but am going to put heatsinks on the RAM and other parts that need it with a fan blowing towards them.
