8800M GTX SLI vs HD 3870 x2 crossfire

does the ati even compete with nvidia in these two cards? anyone have any numbers?

 

8800m gtx > 3870 > 8800m gts

 

Actually 8800m GTX SLI even beats ATI 4870 the desktop in gaming. I know since I have compared the too. This where SLI is supported of course.

 

numbers neone? subjective replies work as well, but less convincing.

 

my comment was based on the test Neil@kobalt - Clevo retailer did 2 months ago.

 

care to link me? i can't seem to find anything. these are numbers on SLI and crossfire correct, not just single cards?

 

truth spoken, believe or not. and don't ask me for links, he posted it over a month ago.

single card, tested on clevo m860tu.

 

thanks! very convincing! i'll just take your word for it!

thank you for your input on single cards! have any input on SLI or crossfire?

-------------

on subject, i have yet to find some numbers regarding the 8800M GTX SLI vs HD 3870 x2 crossfire, if anyone could provide some input regarding the two setups i would greatly appreciate it.

on single cards, the 8800M GTX vs the HD3870, the 8800M is a clear winner in 3dmark and fps.

however in the NUMBERS on notebookcheck it reads that the 3870 is a Higher clocked Mobilty Radeon HD 3850, and looking at the 3850 x2 crossfire on the same site, it actually beats the 8800M GTX SLI in 3dmark 06, yet still has lower FPS. so, it would logically follow that the 3870 x2 crossfire would have even better numbers than the lower clocked 3850 x2. am i right? who knows... i've yet to see actual numbers. and if notebookcheck is legit or not, its still numbers and its more convincing than someone saying, "this card > this card > this card"

thanks nirvana for your quick response and input, i do value it and appreciate the effort. if you can provide some factual, objective information i would appreciate it even more! anyone else care to enlighten me?

 

When comparing them as single cards, the 8800M might be better than the 3870. However, I wouldn't draw conclusions just yet comparing the 3870 crossfire to the 8800M GTX in SLi (even though notebookcheck.net has some numbers). This is because recent comparisons show that Crossfire scales better than SLi on average.

what makes me mad is that Crossfire Performs Better than sli with NVIDIA Games.

 

HD 3870 Crossfire = 14,850 in 3dmark06

8800M GTX SLi = 13,500 in 3dmark06

 

My 9800m Gt Sli , fresh run

 

Ok still lower than HD 3870's in crossfire and your running a quad core CPU, the laptop with 14850 on 3870's only has a X9100 extreme.

 

wait until there are some benchmarks done, forget the 3dmarks scores, they mean not alot when comparing to real world performance.

 

I agree, game performance is what counts.
All I am saying is they are both more than enough to handle any games, and the 9800M GT's can play everything very well.
Until I see screen shots of actual 3DMARK06 scores with crossfire I will be a little wary of just some scores somebody posted.

 

Proof of this? I'm interested (and skeptical )

 

The thing I worry about the OCZ whitebook, ( I figure that's what laptop you are talking about) is the heat, with such a thin chasis and a X9100 CPU with crossfire the thing is going to run hot.I hope they have a good cooling solution for these laptops.
I have to admit It does look really nice with the backlit keyboard, and I can't wait for a full review of one when they come out.

 

hes talking about 2x 8800 gtx vs a single hd 4870.

 

It's useless talking about performance of CF HD3870 Mobile & SLi 9800M/8800M GTX. nVdia clearly win in the end. Last generation ATI desktop cards fail to outperform nVIDIA cards. HD3870 Mobile based on R6XX core & 9800M/8800M GTX based on G92 core . If you can google about G92 vs R6XX then you'll know what I'm talking about & you can understand what will happen with the mobile solutions based on those cores.

We want to wait until ATI release R7XX based HD48XX mobile card, It can beat nVIDIA G92 core easily.Desktop version proves it & even latest GX260 failed to on par with it .BTW we want to remember some games run well with ATI solutions & some run well with nVIDIA solutions. Actually everything depend on drivers in the end.

 

No offence, but its completly ill-informed to based such claims off desktop series. These cards are toned down, and broken down so they do not get as hot or consume as much power. They may be based off of such a core, but they are not even close to the same card they were based off of in the end.

 

I'm not 100% on this but from what I've heard ATi likes to keep its mobile chips close to the desktop ones, though with the 48XX heat issues I guess they may have to change it up.

Still, it's all speculation for now.

 

We'll see some benchmarks of the 3870 crossfire mobile soon enough.

 

Your assertion is flawed. While at full speed in a desktop, G92 does generally beat RV670 (at least with AA enabled), RV670 is a very small, cool-running chip. It doesn't need to be scaled back anywhere near as much as a G92 does to fit into a laptop.

The Mobility Radeon HD 3870 has almost the exact same specs as a desktop Radeon HD 3850! The 8800M GTX, on the other hand, is specced in the same neighborhood as the desktop 8800 GS, with a larger memory bus width and slightly lower clocks.

What heat issues? The high temperatures are due to ATI deliberately electing to run the fans at very low speeds in order to minimize noise.

 

actually, the 3870s are better.

Mycizmo tested 3dmark06 with the whitebook : 14850

I think that's better

 

I taking about general performance numbers. What i saw & heard is ATI can't beat G92 , so maybe it's wrong with the mobile parts. BTW i'm ATI fanboy

 

3DMark06 works better on ATI hardware. We need actual game number to see who's going to win.

 

In the end FPS is what we should be comparing.

And as much as I'd love to hear that the 8800M GTX's beat the desktop 4870, that's highly doubtful.

 

Woops. I know I just read that yesterday :/

 

I have also heard crossfire does not perform as well as Sli

 

Yes sure I compared Crysis and Bioshock. Scroll down to my username Magnus72 in this thread. That was my two 8800m GTX in my laptop against his single 4870.

Very cool, but it looks like his average was around 42 and yours was topped at 70 (screenshot), average (according to log) was about 31... unless I'm missing something.

Either way, those are very nice scores dude! The only thing I feel is that price is not justifiable for such performance; I've decided split my $2k computer budget into $1200 for a Nehalem desktop and $800 for a cheapie laptop... still, the 9262/Whitebook/m1730 are so cool ha...

I'd extend budget to like $2.5k if I were going for laptop but I guess there's no point (for me at least).

So I've gotta ask (and no offence, don't take it the wrong way): why did you buy an uber powerful laptop that's super heavy/immobile? Is it like mobile workstation/CAD work or...???

 

I'm buying an ocz whitebook instead of a desktop mostly due to space restrictions of a dorm. I also do quite a bit of traveling, and having a laptop instead of a desktop is quite convenient. The ocz whitebook just seems like a good compromise between a desktop and an "on the go" laptop.

 

Yeah it´s a mobile work station, I work a lot with 3Ds Max, though it isn´t super heavy. Of course you don´t want to lug it around on your back for a few hours. But it´s a nice system that beats lots of desktops out there. I do have an desktop computer myself too of course.

However I game a lot and having a great laptop to run games at native is always nice. This is also my first SLI laptop.

 

I have seen the video of the Arima W840 running 3DMark06 and I must say I was impressed if it is true. I am just happy to see ATI finally coming out with something to compete against nVidia in the mobile gaming market. Not that I am an ATI fanboy or anything, I just like there to be some competition, helps market growth and technology. (not sure if thats true, it sounded good to me though )

 

ATI cards run hotter than nvidia, and preform way better in desktops compared to notebooks. On a x1950 pro desktop, I can run crysis on high @ 1680x1050 with average of 20 fps...

The 3870's will preform perfectly, people just like to say they're not as good since they're ati's.
