GTX460m Sli vs AMD 5870m Crossfire?

Hi guys, probably been done to death, this one...but I could do with some info. I am looking for as much info as possible as to which of the above two configurations is the more superior.

Ive been on a few reviews etc but cant seem to find a DIRECT comparison of them side by side that is not biased in any way.

I have checked the info on notebookcheck for both set ups and whislt NBC have it listed above the 5870's , with a little bit more digging into the setups they used whilst "testing" the both, seems that although the figures show that the sli is better, the rigs used are vastly different and provide incomparable results.

5870's
[X] HellMachine (HD 5870 Crossfire)
Intel Core i7 720QM 1.6GHz
Mobility Radeon HD 5870 Crossfire (700MHz), 2x 1024MB (1000MHz) GDDR5, 8.753.0.0 (10.10)
4096MB RAM

460m's
[X] XMG U700 ULTRA
Intel Core i7 (Desktop) 950 3.1GHz
GeForce GTX 460M SLI (675MHz), 2x 1536MB (625MHz) Shadertakt: 1350 MHz, GDDR5, ForceWare 259.51
12288MB RAM

Obviously, there is a huge advantage for the 460m's in this test as the rig has a desktop 950 vs a 720qm....and also 12gb Ram vs 4gb Ram.

Based on the figures I looked at for Metro 2033 on Ultra, they both come out at 18 to 18.5fps.....

So, on that conclusion, seeing as how Metro 2033 is a very cpu dependant title, it seems apparant to me that its an extremely unfair advantage to provide these results using such vastly different cpu's.

Im just trying to get it straight - I have 5870's now and IF someone offered me a system with gtx460m Sli, I personally, would consider that to be a backwards step.

If anyone can give me some feedback on this, that would be great...any links for additional comparisons greatly appreciated.

I wonder how the 460's would compare to the 5870's if they were tested on an identical rig? - anyone??

TIA
Stevie.

 

i personally think that 460m are just a little slower

 

I'm not sure about the SLI/CF setups, but a single 5870m beats a 460m easily, even a 5850m beats a 460m most times.

I'd expect the 5870 CF to beat the 460m SLI in most games.

And you can adjust the voltage of a 5870m and get some pretty nice overclocks without any issues, the 460m voltage can't be adjusted, at least I have no idea how.

 

I don't think you'll spend much time noticing the speed differences, but I'm not a fan of a desktop CPU in a notebook form factor. The I7 CPU's are plenty fast, so if these two machines are your choice the 5870 and I7 mobile would be my choice

 

Well neither systems are a choice...i was merely trying to gauge wether one is better than the other in terms of a possible replacement system. If i was offered 460sli and i currently have 5870xf, I thought that this would be a downgrade so I wanted to avoid the possibility of such in case the offer of a replacement came up.....

Even though theres maybe isnt much in it, I think the 5870's pip the 460's but Im looking for some good hard evidence LOL

Anyone?

 

So you were offered a M18x with 460m sli? Try convincing the rep to give you 6970m cf... If he doesn't agree ask whether you can pay some bucks for the upgrade...

Anyway, I don't have dual card numbers, but as I said... 5870m beats the 460m almost everywhere...

 

No. I havent been offered ANY replacement system as of yet, I am just researching the subject should the offer of one come up. For example, given my current system, the offer of an R3 would be an extreme downgrade due to the fact that it is only a single gpu system and will never have the ability of being a dual gpu setup. That leaves another R2 but its plagued with issues that are yet, unresolvable - or an M18x.

Obviously gpu options on the M18x are 460m single, sli or 6970xf.

IF....and IF I got offered a M18x (which is yet to be seen) I would want the same or better, certainly not worse and from the notebookcheck figures, the 460m sli seems ALOT worse given the fact its results are buffered with a desktop cpu and 12 gigs of ram and can still only match the 5870's on this particular title (Metro 2033 - one of my favourites!)

Yep. Ive read the single card comparisons but the only dual card comparisons for mobile cards that i could find was the one at Notebookcheck but was obvioulsy WAY OVER BIASED in favour of the Nvidia sli as the rig had 12gb ram and a desktp 950 cpu...yet still only achieved the same kinda figures as the 720qm 4gb dual 5870 hellfire.....which kinda says to me that its not in the same league as the crossfire 5870's as a direct comparison on a smiliar rig would be a different kettle of fish now, wouldnt it?

Basically, if I do get offered a replacement M18x....IF.....I just wanna be sure that when the rep says to me "here you go sir, 460m sli....." that I would be quite right to say "excuse me....thats not really fair because they are not as good as what I have at the moment, are they?"

Was kinda looking for some info to back it up......

Thanks for your reply tho !

 

Hmm... I can't find any good numbers of the 460m sli, seems to be a pretty rare setup, most systems have 480/85m sli...

Anyway, you can simply tell the rep that already a single 5870m beats a 460m... now do some math (I know this doesn't really work that way, but chances are that this convinces him, you can also give him some numbers...)

 

Yeah, I know the single 5870 hammers the single 460m. From what i have read, the sli setup scales better than crossfire so "can" give slightly better results....

I jut need a good backup argument.....something I can turn to and say "here you go....460m sli sucks in comparison LOL"

Im gonna do some more googling!

 

Great thread!!! I'm sure in the upcoming months a lot of people are going to be asking which is better for comparison purposes.
