Which is better? 6870(PC) or 7970m(Laptop)

Well i was just interested to know if my desktop pc with sapphire 6870 non ti will still perform better than the new 7970m On a laptop which I will be ordering this coming may. So if anyone knows, can you put it here or pm me which is better. Thanks in advance.

 

7970m = 3dmark 11 of around 5600 ( 6000 @ 720 )
6870 = 4200 @ 720

the mobile card is faster by a noticable margin its a small bit behind 6970/580 desktop cards ( 10-12%)

 

how about 675m vs 6870? anyways + REP for you.

 

Thanks again for the pm. You made my day

 

7970m destroys a desktop 6870

 

Desktop 6870 should be a bit faster than notebook 675m (stock not overclocked) but not by a large margin.

 

They are correct about the GPU alone... but most games and benchmarks use both GPU and CPU.

The desktop CPU OC'd to 4.5GHz or higher behind a desktop 6870 might skew things a bit.

The 7970m is a more potent GPU than a 6870, but it will be paired with a mobile CPU clocked much lower than a desktop CPU.

 

Lately games are bottlenecked much more by GPU than CPU especially since SB. numbers wont skew that much

 

Since Sandy bridge? Dude even since clarksfield haha. There are a few games that really stress the CPU, and thanks to 920xm, even new games are nothing haha.

 

true, I mean for the past 6-7 years everything is bottlenecked by GPU..

 

The only games that really tax the CPU as much (or more) are 'poor' console ports... GTA IV, I'm looking at you.

But yeah the 7970M is better than the desktop 6870. The 675M is slightly behind the desktop 6870.

 

I agree with the premise that games that tax the gpu a lot are usually bad or poorly executed console ports.
Look at Star Wars: The Force unleashed. First game ran very smooth on my laptop. Second game ran exceedingly BAD on the same system, even though from a visual point of view, there were relatively minor changes that made the game 'prettier' (but nothing that would warrant such a vast performance drop).

Games such as Crisis for example are a different story because that game was specifically MADE for the PC platform in mind (and even back in the day it was not completely optimized until Warhead was released which effectively allowed Medium settings FPS on Enthusiast/High level of detail).

GTA IV is yet another example...
There are numerous examples really.
I don't necessarily mind the console ports, BUT, if you are porting something from the consoles, then take into account you will have to spend more time to optimize it (for one thing) and maybe even improve upon it from a gfx point of view (because computers are able to cope with higher level of detail or better graphics in general).

As for the discussion on which gpu is better... I do think the 7970m is better/faster/more powerful than the 6870 desktop gpu.

 

By how much?

 

Using typical 4200 3dmark11 scores for the H6870 and 5300 for the HD7970m it would be around 28% faster (the HD7970m).

Now this is without official drivers, and some users actually have higher scores for both cards, but in average the 28% figure should hold true. There are important things to take note for though. the HD7000 series have exceptional tessalation performance compared to the HD6000 series as well as other upgrades in efficiency, effectiveness and more. Plus a new architecture with untapped potential.

So expect that 28% margin to be larger in favor for the HD7000 series as time progresses, and if games become more DX11 demanding.

 

Latest benchmarks put the 7970 at more around 5800-6100.

 

Awesome. Maybe 7970m will be a beast for a long time. It even defeated my pc's gpu.hold on 7970m, im coming to get you.

 

the rule with graphics cards and people on the internet, is that if one gpu is 5% slower than another GPU, it is "dominated". If it's 10% slower, "destroyed". Welcome to the land of overly extreme word choice and no moderation.

 

so you are saying that a 7970m is 10% faster than a desktop 6870?

 

35 to 40% better

 

3dmark11

7970m is 5700-6100
6870 is 4200 average

thats a bit more than 10%, add in 6-8 times the tesselation performance of the 6000 series cards .......

 

well...i take back my 35-40% faster..that's based on 3dmark11 and personal testing that i've done in The witcher 2 and BF3

the 7970m is like 100% faster than a desktop 6870 in Crysis 2 DX11 Ultra

AMD Radeon HD 7870 & Radeon HD 7850 Review > Benchmarks: Crysis 2, Dragon Age II - TechSpot Reviews

How i came to that conclusion? the 7970m is a desktop 7870 minus 15% (it is 150mhz slower at stock settings)

So according to those benches @ 1900x1200, the 6870 gets 15fps, the 7870 minus 15% = 30fps

THis is consistent with my tests on Unigine Heaven which is a good DX11 bench. The 7970m scores 60fps @ 1080p, tessellation normal, high, high. The desktop 6870 scores about 26-28fps with those same settings

AND this is with drivers that have been slapped together like a ham sandwich. What happens when i get real drivers? What happens when i have app support and i overclock this another 15-20% or more?

I feel that "destroyed" is fully justified when describing how much faster a mobile 7970m is compared to a desktop 6870

 

LOL yeah, Thanks for this detailed answer.

 

The 7970M is pure beast, worth every penny. Biggest increase/step-up between top of the range mobile GPUs I've seen so far... and I've been playing Crysis 2 at Ultra DX11 butter smooth and my max temp was only 62C. Can't wait to overclock.

 

Did you play @1920x1080 DX11 All Ultra + High Res Textures?
I'm interested in the frame rates you got in MP with those settings. Can you please tell me? I also want to know the fps you got with FRAPS turned on. (or anyother recording software). Even better make a vid of and post it youtube with a link for me
Please reply a.s.a.p
Thank you.

 

i played through one level of Crysis 2 ULTRA DX11 with high res texture pack installed @ 1080p...it never dropped below 40fps...normally hung around 45-53fps. i can finally run these games without having to tweak the settings

 

You can basically google for HD 7870 reviews for 7970M perfomance prediction in games. This beast will OC to HD 7870 speeds with no effort.

 

That is 100% correct. Couldn't have said it better... The 7970m is a desktop 7870 minus 15% (which will be made up with an overclock)

 

So 7990m in September will definitely be faster than 7870 in stock clocks?
And what features do AMD lack behind Nvidia that really matter?

 

If AMD did decide to make a HD 7990m then i doubt it would work on current notebooks that can take the HD 7970m because they would have to go over 100w.

Im not gonna wait until September just because there is a slight chance they might release a faster card.
As soon as i got the cash im calling up my local Clevo builder.

 

Do cpu's make a difference in gaming?
Like 2760qm is $160 more expensive than 2670qm. Is it worth the upgrade?

 

not in gaming no

 

Given that the Desktop 7870 beats a desktop 6870 by 42% in a combined score, I think maybe the whole 100% thing is overhype.

Charts, benchmarks 2012 VGA-GPGPU, 19 - Tom's Hardware Index Performance

Not to say the 7970m isn't a great GPU...

 

Again...i'm strictly talking about DX11 and tesselation performance. The numbers indicate what i say. This isn't overhype. As we start to move away from the old and move into stricter DX11 implementations and see heavier tesselation, we will see a wider gap between these cards.

The 6870 is older and not as efficient at rendering the newer tech

 

We both know that this whole 100% better with X features is misleading.

The 7970m is a great card... the 7870 is too... and yes they are better at newer tech... but isn't that expected?

The problem is that newer tech is so SLOWLY added to computer games lately due to consoles.

Again, its time to slow your % inflation...

 

Kernal, everything i say is backed by numbers

and why is it misleading? Do we care how these cards will run DX9 games?

 

Slick said it was 100% better in Crysis 2 DX11 Ultra. One specific example and you somehow bring hype into the equation?

Judging by the numbers he is correct. Nothing to do with hype, combined scores, or other games/benches. Crysis 2 can be played full on maxed out, 100% better. Actually goes from being eye candy unplayable to very much playable - feels great, believe me.

 

Yours are backed by numbers for one game with one settings set, mine are backed with multiple games from multiple settings sets.

Mine are also desktop vs desktop, and thus apples to apples, you are crossing desktop and mobile numbers.

Which set of numbers are better?

You even deny your OWN findings to highlight the 100% number.

Witcher2, BF3, and 3dmark11 are from your OWN findings and they are DX11 are they not?

Let's keep it real please.

40-50% on average is very real and backed up by more than just one benchmark... it also coincides with the difference between the desktop 7870 and 6870.

 

And, inversely, consoles are bottlenecking game development

In response to OP's query, at stock 7970m should be 20-30% faster than a desktop 6870.

 

So true, hate consoles, seriously wanna destroy all ps3s and 360s out there

 

40-50% is about right.

Where i was going with the 100% on crysis 2 ultra was that as we go forward and games get more taxing, the gap will get larger. the 7970m has amazing DX11 tessellation performance compared to the older 6870. if games make use of these features, the performance increase will get larger between the 7970m and desktop 6870

we are already seeing a huge increase in BF3 with the 7970m compared to last gen cards and this trend will no doubt continue

Playing Crysis 2 DX11 ULTRA was just a pipe dream not that long ago...but its completely playable on my 7970m @ 1080p

 

Wow I really cant wait to get my 7970 and ivy bridge p150em now. Ultra settings bf3 and maxed crysis and skyrim .... epic. Also copped a 256GB crucial m4. Do you guys know how well the 7970 does with Photoshop ? Is it worse than gtx 675m? Curious

 

Is there a photoshop bench? How can i come up with a determination?

 

I'm really not sure I did some googling and the only Photoshop benches I found were all CPU dependent. I guess since I'll have IVY it will probably handle most of my Photoshop needs anyways haha. And the 7970m hopefully will help also. I don't do too much photoshop; I'll be doing mostly CPU intensive finance software once I'm at school and gaming when im not. I really just was curious.
