ATI HD 7970M or Nvidia GeForce GTX 675M

Problably I will buy this month a laptop Clevo P170EM and I don't know what Graphic Card I will put. Or ATI HD 7970M or Nvidia GeForce GTX 675M.
Both are 2GB DDR5. I wasw advice that ATI are a little better that Nvidia, but I don't know what to choose.
I would like the best Graphic card for playig Battlefield 3 if possible in ultra settings!

 

7970M hands down.

Plus, it's AMD Radeon HD 7970M, not ATI. Just saying

 

If you want a Nvidia Geforce GTX 580 rebrand (GTX 675) or the not a rebrand AMD Radeon HD 7970m.
Dont think too much of how much GB of memory they got, wont make that a big difference.

 

Are there any 7970m benchmarks yet?

I would hope it would be better since it is a new card and the 675m is just a renamed 580m. Kind of a big fail for AMD if their new card won't beat a year old card.

 

Should be around a 20% increase, as the 7970M was a 25% increase over the 6990M.

 

the 7970m for sure....a single 7970m is just a tad less powerful than crossfire 6990m. It will be beastly

The gtx 675 = gtx 580m they are the same card. both are on the same silicon, based on the older fermi 40nm architecture

The 7970m is a next gen card and is essentially a desktop 6970 downclocked 80mhz to 800mhz. This you can make up in an overclock. The 7970 has 1536 stream processors...it is identical to a desktop 6970 and hence is powerful

Further, the 7970m is built on the new 28nm process and tdp is dropped to 70w which means it will run cool and should overclock nicely

I'm more interested in how the 7970m will be vs. Nvidia's 680m.

 

I still don`t understand how the 7970M can have more shaders than 7850 and 7870. Or how it can have under 50% power consumption of the 7870 at the same time

 

Yes...the true battle. People keep comparing the 7970m to the 675m...and the winner is...us! Both cards will be beastly!!!

 

Just for reference, the HD7970 is NOT like tha HD6970. The Architecture is different (GCN vs VLIW4) so core by core, the GCN is more powerful. But with sacrifices for the mobile market, the HD7970m will be, at best, around the level of the HD6950 desktop in performance, generally.

And also the numbers are not official as far as we are concerned yet. they could end up being less. And according to rumored benches etc, it should be 30% faster than the HD6990m as tops, so its definitely not slightly lower than Crossfire Hd6990m, but quite weaker and such a setup.

Now back on topic... It's a safer bet to go for the HD7970m.

 

Ok, problably I'll go for ATI, thank you all

 

HD 7970M is waaay better

 

7970m for sure....will perform better at lower wattage of course.

 

The 50W 7950m and the 65-70W 7970m (which are 28nm) should both be significantly faster than the 100W 675m (which is 40nm).

 

With those two in comparison, I would probably go with the HD 7970M. It should be a good 20% or so better.

 

Those 7970M specs are blatantly fake. Stop posting them.

 

why do you say that Kevin...why are they so blatantly fake?

 

How do you know they are fake? Has there been any comment from AMD?

Not sure whether notebookcheck has some other sources, or what was their primary source, but they do provide links to two:

AMD Radeon HD 7970M vs NVIDIA GeForce GTX 680M

http://www.techarp.com/article/Mobile_GPU_Comparison/ati_4_big.png

 

The numbers just don't really make sense. Both AMD and Nvidia base their mobile GPUs on the desktop parts as far as I know. So which part is this supposed 7970M with 1536 cores and a 256-bit memory bus based on?

7850/7870? No, because those have less cores at 1024 and 1280.

The 7950 that has 1792 cores? No. Even though 7970M could be a 7950 part with disabled cores, they still have different memory buses. And even if we ignore that, there's no way the 7970M could possibly consume less than half the power of the 7950 while running at the same clock speed.

Also notice the techarp.com chart says the release date is Q1 2012...

 

I heard that Nvidia graphic card usually do better on gaming than AMD when both specs are the same. Wonder if 7970m would noticeably outperform 675M on gaming even if it has 20% better benchmark score.

 

^^^^Exactly.

This 7970M would be as fast as the 7870, at less than half of its max power draw.

Seriously?

 

I don't quite follow.

According to notebookcheck.net the 7950m will reportedly use 50W and the 7970m will use 65-70W.

 

we are stuck at 7970m (I know it is crazy) but I think 7950m is worse of a claim, 50W TDP and 4.2k 3dmark11, this is ridiculous, it means, beating 580m bad at HALF the power draw.. come on

I know why you are confused, because it is impossible to assume they are talking about actual desktop of the same family but it is true, they are talking about HD7950, the 200W TDP desktop monster

 

I know that the new Nvidia Graphic card (GTX 680M) is about to be released and it could be better than 7970M, but what I'm asking is a comparison between 675M and 7970M for gaming purpose, in my case BF3.
I know both graphic cards are the best at the moment for laptops, but if one is definitively better than other that's what I want for my Clevo.
Like I said and for what I've read I'll probably choose the ATI.

 

This is false.
Some games will favor AMD, and others will favor Nvidia - raw performance wise, the older 6990m is essentially on par with 580m (with maybe 5% going in Nvidia's favor in benchmarks - which is practically nothing a gamer would notice, and besides, real-world gaming will show favoritism to different gpu's).

If the theoretical specs posted before are accurate, it's quite possible/likely that a 7970m will outperform 675m.
Besides, the 7970m is a 28nm gpu.... the 675m is 40nm (a renamed 580m).
To that end, it would indeed be very shameful if AMD is unable to beat Nvidia in this department either way - with a lower power draw on top of things.

Ultimately, we won't know anything for sure until the gpu's can be tested.
And finally, to those who keep insinuating that AMD can never get close to Nvidia and that the specs posted are fantasy - reserve your judgment until the gpu's are released and stop under-estimating AMD (we may not have concrete info, but that doesn't mean AMD is incapable of beating Nvidia).

 

Really it's just about preference.

If you like to play a lot of PhyX intensive games and want good graphics for it go Nvidia.

If you don't, and want a cheaper card that runs just as fine without the premium price tag, go for broke with AMD.

 

Well from the info that we have so far on notebookcheck.net and a few other places, even the lower tier and cheaper 7950m looks like it will be significantly faster than the 675m, and the 7970m will be faster than the 7950m.

At any rate, as I don't think you can buy a laptop right now with the 7970m, you will need to hold off until it comes to market and soon we should start seeing some benchmarks and a confirmation of whether the specs listed on notebookcheck.net are accurate or not.

 

Something tells me you've hit it right on spot, we'll see, never the less the 79xx series should be sufficiently strong.

 

What about the new GTX 660m compared to the 7970m?
I know it's got kepler 28nm architecture so it couldn't possibly be too far behind

 

According to notebookcheck.net, the 660m is significantly slower than the 670m and the 675m.

 

I'm from Portugal and this is where I've seen the laptop:
Home | WSI Bytes & Gadgets - Portáteis à sua medida - Loja Online - Asus, Clevo, Sony, Toshiba, Dell, HP, Samsung, Compal, Apple
Don't know if they already have this graphic card or I have to wait...

 

Seems pretty legit to me...its interesting that they are quoting the same numbers on the Clevo laptop...the 7970m is 800mhz and 1536 stream processors

Does it make sense that the 7970m is based on the desktop 6970? the desktop 6970 has 1536 cores.
I was told that the 7970m is essentially a die-shrink on the desktop 6970

The current 6990m is based on a desktop 6870

 

2 rumors floating around:

#1: 7970M = 675M
Allthough this may be true, 7970M is still a 60W GPU while 675M is a 100W GPU. 675M is hotter and draw more power from your battery.
One forum member have bought a Sager on a presale and according to him the 7970M setup cost 100 Euro more. Its up to you to decide wether 40W less TDP is worth 100 Euro more.

#2: 7970M = 135% x 6990M (or 35% better than 6990M)
Rumor number 2 says 7970M should score 35% better in benchmarks than 6990M, and produce 25-30% more FPS in games than 6990M, which also is a 100W GPU. Since 6990M and 675M are so close in terms of performance, you pay a little more for much performance (over 675M) and you get a less hotter GPU and more battery life out of your notebook.
If this is true it is really a non brainer

 

I've seen the sources for the #2 Rumor (notebookcheck.net and a few others), which suggest that both the 7950m and the 7970m will be significantly faster than the 675m. However, do you have a source article or website that says the 7970m would be equal to the 675m?

 

Yes its out there. I don`t remember where but search and you`ll find. I know some chinese resellers have said 7970M = 675M.

That notebookcheck is quoting his specs from TechARP, a ususal BS site, and that guy from the benyouhui thread have later posted that 7970M = 675M if I remember correctly so he changed his mind later.

But I think rumor #2 is the closest to the truth (and this rumor is the latest from the chinese community) but I keep my mind open for sudden disappointments

 

Dracula666 you have to wait, they don't have it in stock. According to their indication they should arrive by the end of this month.
And Dracula I'm from Portugal too, i've allready ordered mine from WSI.
Bro if you want to buy one I recommend you get in touch with them.

Cheers

 

Didn't know that. I thought they have it in stock.
That's why they are a lot of speculation about that ATI graphic card and no certainty.
All I want is to my future Clevo comes with the best graphic card available

Maybe the 7970m is 30% faster at overclocked 100W and just as fast on stock 60W.

That would make more sense but I would also believe it is faster on stock also.

 

For either of these rumors to be true, this 1536 shaders @ 800MHz business has to be a complete fabrication.

With those specs a 7970M would be at least 160% faster than the 6990M.

 

Yeah I know. I don`t believe these specs for a second. Die shrink of 6970? A 250W TDP shrunk down to 60W? Hah. Downclocked 7950 which is a 200W down to 60W? Still too much

 

The AMD graphic cards doesnt support cuda or physx, so hands down for the GTX 680m! I've always loved nvidia cards, and always preferred them over AMD =)

 

Neither of those features does much for a gamer though, and Nvidia will never love you back, save your love for someone important in your life, not a product.

 

Name two upcoming games which are to use PhysX, without using a search engine.

......yeah.

 

I still hope we'll see the P170EM with 7970M shipping out mid may...

 

Just a thought off of the top of my head.....

Out of the two rumors listed above, I can't see #1 (7970m=675m) even being a possibility. The 6990m is equal for all intents and purposes to the 580m. The 675m is a rebadged 580m. If rumor #1 were true, that would mean the 7970m is virtually the same speed as the 6990m, which would be a fail of epic proportions.

#2 seems like the likely outcome, if those are the two choices.

 

Yes, according to notebookcheck's rumored specs, both the 7970m and the 7950m are deemed significantly faster than the 580m and the 675m, which are in turn slightly faster than the 6990m.

Hope AMD decides to release some concrete info soon.

 

Agreed. In fact, the one game that featured nice PhysX effects was Mafia II..but it made the game stutter, and this was on a desktop PC with a high end GPU. It's definitely not a reason to pick nVidia over AMD, especially on a laptop.
