So was I, it took me by surprise.
Great review Brent/Kyle.
Could you guys comment on how the noise level compares to a gtx 275/285 at load? Anandtech's review seems to show the 5870 being about 13db louder than the 275, or pretty much the same as the 285. Is there typically that big a difference in noise between the 275/285? I was under the impression they used the same cooler. Using a 275 right now and its pretty quiet, even at load.

Head over to the DC forum. Myself and other members have offered to help [H] come up with some F@H-related testing methodology several times before. All you have to do is take us up on the offer.Negative, though I have floated the idea of adding in some compute applications for testing. It is something I'm thinking about, but need to find the right implementation and representation of the data, and usefulness of it. I am looking into it.
AF is one of the biggest factors of image quality to me, so I think these improvements are awesome. I'm ambivalent about the SSAA. It was always an inefficient way of removing aliasing, and its performance impact and overall IQ reduction don't make it a very attractive solution. It's nice that they added the option, but I don't see it getting much use.What do you all think about the AF IQ and addition of Supersampling AA? Like/Dislike/Don't Care? Give me your opinions.
Truly amazing review i'm speechless !!! so deep and detailed great job guys!
The card is impressive even someone say the fps is kinda low in Crysis i think its good!
being 10 % slower then GTX295 is nowhere near weak for 100$ less and free from scaling issues! Also i already order 2 of this so the performance in Crysis won't be issue for me Oh and i already forgot the Arma II numbers are amazing also!
Now i just hope the apdate of the review for 5870 in crossfire will come soon enough
Can't wait to get my hands on this babies!
great review guys, I also looked at the anandtech review, from looking at that I do think that after this gen ati better go 512bit on the memory bus otherwise they will make a great mistake, because in AT review the gtx 295 started to match or beat its performance by a little at 2560 resolution, while at 1920x1200 it was performing like a champ and coming out on top in most of the games, which is perfect for me because I have a 24inch monitor, and also the card should be fine until next gen, but next gen better have 512bit memory bus otherwise amd will be cutting their own feet off, I do think though it will happen amd is probably just trying to stay at the same power envelope, and with the next shrink it would definitely be possible. I just hope they don't just depend on the speed of gddr5, because it won't do any good when you got so much horsepower under the hood and you are limiting it by memory bus
I know a few posters @ Rage3D use it for WoW with nVidia cards. Might help them in deciding what card when upgrading. I don't use it, but nice of AMD to give the user the choice.What do you all think about the AF IQ and addition of Supersampling AA? Like/Dislike/Don't Care? Give me your opinions.
The GTX 295 does not have a 512-bit memory bus, it has a 448-bit memory bus. The memory bandwidth with the 448-bit memory bus and GDDR3 is 112GB/sec. Therefore, HD 5870 clearly has much higher memory bandwidth.
Enjoyed the review and I liked hearing the game devs have had HD5870s to code DX11 on since June.
Looking forward to the other reviews comign this week on this series. As usual AMD is first out the gate with good new tech but no software to help utilze it along has happend a couple times in AMD history its unfortunate nvidia, intel have the pockets to hold things back at there desired pace.

Brent... no you may not click a red arrow to see where he said it said:One interesting result of enabling EDC however is that overclocking consequences have now changed. In the past, when you overclocked memory on a video card it would ramp up in frequency until the video card would start throwing out artifacts, and then crash. Now when you overclock memory frequency your performance will increase until it reaches its climax and EDC kicks in fixing errors in the memory due to the frequency being too high. This means EDC will fix these problems and your performance will start to actually degrade as you increase frequency and EDC has to work harder at fixing the errors. There won’t be as much flashing polygons and artifacts anymore and no outright crashing from overclocking memory, you will only see a performance decline. Therefore, the goal is to now overclock memory until performance starts declining, then back it off until you’ve reached the point right before the decline, and that is your maximum stable memory overclock."
That really doesn't matter though, as long as they can keep pumping up high amounts of GDDR5 frequency, they can gain memory bandwidth as they have done with the HD 5870. The HD 4870 has 115.2GB/sec of bandwidth with 3.6GHz GDDR5. The HD 5870 has 153.6GB/sec of bandwidth with 4.8GHz GDDR5. The GTX 295 does not have a 512-bit memory bus, it has a 448-bit memory bus. The memory bandwidth with the 448-bit memory bus and GDDR3 is 112GB/sec. Therefore, HD 5870 clearly has much higher memory bandwidth.
aww no apples to apples?!?!? what the....
