One of the best comparisons I've ever seen!
Crossfire-X onfire :D
Where is Shintai? :p
Interesting to say the least... To sum up, Crossfire scales a lot better with the 38xx-cards than SLi does with the GT... But 8800 still has better AA-support... Good news for people looking for a relatively cheap but powerful system on both sides of the fence...
Best Regards :toast:
agreed, this makes me think there may be hope for the 3870x2 to outperform the dual g92 card
nice test....
Absolutely excellent!:up:
Excellent compare! Hoorah for ATI! :woot:
Thank you!!!
exactly what i've been looking for, thanks for the info :)
my friends in the market of buying 8800gt's or 3870's and this should definitely help him out
That looks very nice. I hope ATI's new R680 is as good as two 3870's in Crossfire or even better:)
Looks very nice, hopefull this will bring out another graphics price wars!!
victory for consumers!
Brilliant comparisons man.
3870 CF looks pretty badass. And wow, imagine that, CF does a lot better in Call of Juarez than SLI. :rolleyes: Not that the designers of COJ has a direct partnership with AMD/ATI (see the "plays best on ATI" label on the game box if you don't believe me). I guess COJ is AMD's little "pet" game that shows Spyder's prowess in the canned benchmark arena.
so I guess it's the same for the Lost Planet "canned" benchmarks?
Crossfire is indeed impressive, but since I can't afford SLI or Crossfire, I am happy with my single 8800GT :)
i noticed the 3870 takes a huge hit in AA performance compared to the 8800 GT. while the 8800 GT suffers a bit more at higher resolutions than the 3870 when AA is off
if it wasn't for the AA performance i would say it kills the 8800 GT when considering the MSRP
made my 3870cf decision so much easier. i'd wait for the r680, but i already sold my parts, lol...
OS Vista
Mobo X38 vs NF680i
this clearly shows that ati is well on the path to win this round and since they are on intel chipset they can oc with a quad making them the defacto winer
and since both lost planet and COJ are way one sided if u ignore those those cards are dead even, and how dose ati win on QW i though that thats a shader limiting game thats amazing performance from ati
Cookerjc: did you see this thread? It seems so easy to do. Oh well, I already ordered my 8800gt from dell today...
http://www.xtremesystems.org/forums/...d.php?t=166908
Crossfire certainly has potential, and scales far more efficiently than SLI. Crossfire clearly has the win, although I think in terms of single cards the GT would win.
hmm when u guys do a 8800gt sli
i have some issue with it..
its different from the g80 core sli.
Awesome comparison. Though I do plan to go crossfire since no nvidia offer will likely handle overclocking a Quad core or higher, again I'd like to point out the the operating system used was windows vista. As most of you know, 3DMark06 scores significantly lower in Vista than XP with Nvidia. Not sure about ATI. I'd like to see results ran on win xp. Especially since it's rumored that winxp sp3 has performance boosts.
Totally sweet comparison!!! Thanks a lot man. It looks like Nvidia is the way to go for single card and ATI for multi card.
Im actually impressed with AMD/ATi! I think I will purchase 2 3870's and a maximus formula motherboard to have them both @ 16x speeds, and still retain my DDR2...... Should be a nice improvement from my single 8800GTS 640
cookerjc you are my new hero :) ok, maybe a touch o.t.t but that is interesting information.
I've been torn between keeping my GT or getting CF, this pretty much swayed me as I'm finally moving to vista in the near future and the cards are pretty even.
Now where to find 3870's in stock and not overpriced...
nice comparison, thx :toast:
How about in crysis does crossfire also scale better?
Great review, I would love to see some O/Ced 3850's match the stock 3870's. At 179$ for two it would be a steal. Also would be great to throw in a single 8800Ultra as well.
a single 3870 is an improvement over an 8800gtsQuote:

I tried a single 3870 and boy was this card crap, my 8800GT trounced it in every game.....cant speak for crossfire as i havn't tried it yet.
LMFAO,,, wow bro. Don't think I've ever seen anyone soQuote:

EBL
Ati scales very well in crossfire how about at a lower res will it scale there too?
nice test. thanks for ur info m8
I'd like to see 8800GT 256 in SLI v. HD3850 CF. That would also be interesting.
Anyways--nice review.
sorry guys no crysis comparison is because at first we run a small test and find out there's about 20% boost with 8800GTX SLI.
http://en.expreview.com/?p=19
here is the 20% boost :(
But while we runing this comparison in both SLI and CF there is not boost at all. We can not figure out it is a game/hardware/driver problem so we just drop this game.
hmm... thats unfortunate. hopefully with patches/new drivers, cf and sli will work. do you know if cf works with 2900xt? if it does, then maybe its a driver issue.
wow....great comparison....didnt think they'd be that close
you know it wont. This is just unfortunatly going to be seen by us insiders :(, unless of course ATI makes this into a big lathering deal (which they should), but they wont.Quote:

I really wanna WC cept for the $$$ needed! (edit: also im runnig P29... i cant find a mofoin new floppy to run the damn bios flasher... and the softwares horribad, like hell ima use that).
X38/P35 looks to be able to put out simply insane speeds, while running that memory controller [nb] at a reasonable temp. that, coupled with the fact that the HD 3870 performs on par with my 8800GTS 640mb (yeah I know I havn't looked at it that way but I should) and comes at a much lower price point means I could jump to X38, and two HD3870s with minimal cost included. I would get the higher OC, and more GPU performance!
Should I pull the trigger? what do you guys think, as an X-mas present to myself: Water Cooling or swap for a P35 (I DONT like this whole 4 and 16 pcie crossfire but asus has that crosslinx) or X38 and two HD 3870s?
If you don't like anti-aliasing. :p:Quote:

cookerjc could you do crysis on all high and all veryhigh to see which cards scale better in this game.
You might want to read the driverheaven review if you are contemplating using CF... Pay special attention to 'The Bad' and 'The Ugly' section - usual driver issues with multi gpu configurations.
A single GT will deliver consistent performance and is better than the 3870 (but costs a little more).
Crossfire doesn't seem to be as supported as sli. I cancelled my 3870's, I want hassle free gaming without having to wait for drivers to take advantage of CF...
Both decent cards it really depends on your needs.
Roll on '08 and the D9E...
cookerjc,
Could you test crysis crossfire performance on XP with Crysis hotfix drivers (uninstall previous cat's first!) and retail crysis? There should be big boost compared to single card setup or SLI according to this: http://www.forumdeluxx.de/forum/show...postcount=1255
Nice review CookerJc,
this answers alot of the questions i had when i purchased these cards..
you just made me feel good bout my 3870 x 2 purchase =)
will do after our current jobs' done..Quote:

One of the best comparisons ever :)
This 3870 in Crossfire rulz :)
Hoping for new results of 8800GTS G92 to possibly replace my 8800GTS 320MB but as i look, probably will go for dual 3870 :)
There are serious issues with everything in Vista :)Quote:

i think it's funny how emo attached GT fanboys get so cut up now that they realise their card isn't so mighty after all.
the 38xx series have alot of aces up their sleeves and the performance difference is minimal to none existant at times.
crossfire 3870 is doing me ok ..here's my 20404 06 run in Vista X64
http://service.futuremark.com/compare?3dm06=4094406
3870 Crossfire is far superior than any Nvidia SLI offering below the 8800 GTX's, but only when running windows vista. Vista's performance seems lower than xp's when running the same hardware, so most gamers haven't made the switch. Again, I'd like to see a winXP comparison as I'm not sold on grabbing a couple of 3870's just this yet. ;)
February '08 = Nvidia D9E
:D
What does that have to do with this thread?Quote:

Same goes with the current 3xxx's they are simply a refresh of the 2xxxx Series to 55nm, ATi just decided to call them a new generation.

And my point still stands, as the 2900xt is a relatively new card as well.
So, what's it gonna be?
2x3870 or 8800GTS 512?
Depends on what resolution you gonna play your games in.Quote:

So still think the 2x3870 wins in 1900*1200 vs 8800GTS 512MB.
It's not just a matter of resolution, it's also a matter of what games the user wants to play. I'm not going to try and blow smoke up anyones' arse, but I see a lot of games being tailored towards Nvidia and SLI. If you are a CoD4 player, I'd recommend the GTS 512MB. CoD4 doesn't take advantage of CrossFire and I learned that the hard way. Research your games first before making the final purchase.
I am not gonna buy 400$ cards because of one stupid game :).
For me its resolution that counts.
no competition in crossfire supported titles.Quote:

What source did you get your info from???
if it keeps getting too tailored nv will have a lawsuit again like with doom3, but crossfire works in those games and it dose in COD4 since ati put some drivers out, but nv gets sli out quick for new games since they get to code well before ati dose but then again this will also lead to a lawsuit also if it gets out of handQuote:

anyone got some cod4 bench scores? my google skills are lacking
had no idea the 3870's in xfire were even comparable to an SLI gt setup
O_O
In windows vista. Windows xp is a differnt story however.Quote:

1st cod 4 bench i found was on toms, but its 975 v680 so the ati cards are at a slight disadvantage and its on toms who gets nv money for their ads but ill keep looking, its within 1-2% so ati wins the price to performance and x38 they should win
http://www.tomshardware.com/de/HD385...-239891-8.html
i will be running at 1920x1200, so the gt is kicking ass..
i wonder just how much bus speed difference will affect the outcome on a x38
Really? In what way?Quote:

I just recently installed the Multi-GPU patch from M$ and haven't had time to play CoD4. If that fixes the problem, I'll let you know.
Well thats a good review in showing how much of a diffrence 512MB is Vs 256MB.Quote:

They have HD 3870s for 193usd and they are always OOS. So are the 3850s now :p:
Personally, I really wish Intel had bought ATi instead of AMD.
very nice comparison, very well laid out :)
Very nice, thank you! Just what I was looking for and best of all, excellently laid out for our table searching eyes. :D
All good, especially Xfire scaling and nV AA/AF perf, but this ATi core with AA/AF really does take a monstrous hit. They need these issues resolved and its definitely something integral to the core itself if it hasn't been since R600. I mean -20FPS by 8800GT SLI and nearly -80FPS by 3870 CF!? That is seriously an area needing attention.
Would be nice if someone compare 3870 with cats 1.12 vs 8800GT lastest drivers.
nVidia has shot themselves in the foot by limiting SLi to their motherboards. Having said that, the firing squad show that in some cases SLi can scale close to 100% per card and that the only way to play crysis at 1600x1200 on very high at 30fps is three ultra's.Quote:

interesting comparison and also good test
I can tell you it's not.Quote:

I've used XP 32 and now on x64 with these cards, and yes, crossfire does make a big difference. You just need to use drivers other than the ones on the CD.
Right now, the crysis hotfix drivers work very well. Even in games other than crysis.
This comparison rocks :D
Should definitely help anyone building a new rig anytime soon
Hmmm.... Kinda makes me consider dropping my 590SLI board and dual 88GT's for the new 790 board and dual 3870's.
THis thread makes me wonder something similar as well..Quote:

Has anyone done this successfully here at site - that anyone knows of?
I would suspect that if it can be done, Asus would be likely to be one of the board makers that support both - intentionally or unintentionally. Anyway, I've always like Nvidia products but I'm a big AMD fan.... Maybe it's time to look at the AMD Chipset boards.
this helps a lot.. i'm looking for my new card in this near future lol
ati on fire !!
nice tests
