AMD 7970m vs GTX 680m

yeah, nvidia does TDP whereas AMD does ACP (average chip power?) something like that ^^ messed up!

 

for example the tdp of the 7870 is around 150w, while the power consumption is around 108w ish

and no this debate aint going anywhere

 

Nope. Looking at the Geforce cards the TDP is indeed lower than the power consumption like I said. Atleast for desktops
EDIT: 95% of the AMD GPUs too

 

Yes, even its maximum is lower than its TDP, so its typical is much less. 3dmark vantage will note make your GPU use its max, nor your system for that matter.

 

Evidence to back that up?

 

I read somewhere even the best games don't push our gpus to 70-80% of their TDP, is that true?

 

I don`t know but there might be more GPU load and maybe higher power consumption with the Extreme preset? Not shure if you get less power consumption with Performance preset though..

 

From Techpowerup:

3dmark is not a stress-testing application that jacks up GPU and memory usage to 100% throughout the test. If it were, every 3dmark run would be the equivalent of running Furmark (which it doesn't, thank goodness). That's why Maximum power consumption is a property of the PCB (everything minus the die) rather than a reflection of GPU die consumption. Peak power consumption would be a better indicator of the actual TDP as it's more reflective of intense gaming situations and helps explain how two GTX 560ti dies clocked at 620mhz can fit in a 100w thermal envelope.

 

No.

10char

 

Aha right. Well thanks for clearing that up. So Furmark would be the way to go

 

ichime, very nice picture, and don't think I didn't realize you are stating 7970m crossfirex in your sig so you are the first to try crossfire in r2, good luck bro!

 

Nvidia's was the complete structure,while AMD only counted the chip alone, not even including the RAM. Which was how a bunch of people were fooled into believing the 5870M had a ridiculously low TDP, when added all together it was closer to 75W than it was to 50W.

They have changed that practice, and now measure it the same way as Nvidia.

 

Thx and yeah, the price (at the time of purchase) was too good to pass up given the performance of these cards. Maybe I'll go back to nVidia for the sake of more SLi testing if the 680M performs well and is at a good price point, but I'm glad to be going back to the red team

BTW, any progress on your card?

 

Hopefully will be delivered tomorrow but Table is nowhere to be found we'll see! crossed fingers

 

Ichime, you, sir, have far too much time and money on your hands!!!

 

Dumb question, how can I find out who repp'd me, and for what?!

 

Upper left hand corner, click on "User CP", itll give u an overview of the ten most recent reps u received

 

Just bought a Clevo (which is apparently called Multicom in Norway) with the 7970m. My fingers are literally itching, but I'm gonna have to wait for at least 1 month, oh the agony!

 

Its called Kunshan 150e/170e in Norway. Multicom is the company that sells them, its only nitpicking from my side though. Congratz on your order!

There is so many different dates of delivery around. My reseller states 10th of May... Some ppl have 5th of may...others say late may and some even early june. I'm rly hoping to get mine before D3

 

Congrats on buying it.
Cant go wrong with Multicom, nothing but good service.

Had issues with my Clevo P170HMx a while back, and it turned out to be the Intel SSD 510 that was causing it.
I shipped it to them and 3 days later i recieved my replacement SSD.

 

I don't know if I'm being daft, but some people seem to be saying that Alienware's are available to order with the 7970..... but I can't see them on the website?

Am I being a bit..... special....?

 

Are you on the Dell US website? And only the M17x has it as an option, no M14x or M18x (yet).


(Preliminary ship date was 1 June by the way, didn't capture that, nothing else changed - 1920 x 1080 cough cough).

 

The great internet dropped more news for us to speculate on today :

As explained earlier, along with specs, the GK104, GTX 670 looks like its going to be our GTX 680M. the GTX 670 is a 150W GPU, so Nvidia must take away 50W to fit in to the 680M, which shouldnt be so hard since GTX 560 Ti was a 170W, and they managed to remove 70W to make the GTX 580M.

Anyhow, GTX 670 have been benchmarked a little. Here are the results. Based on Vantage the 670 is:

Performance: 29471/26297 = 1.12
Extreme 1080p: 15270/12318 = 1.24
Average performance over the 7870: 18%

http://www.legitreviews.com/news/13041/

Seems like Nvidia takes away the midrange throne from AMD as well.

Comparison with 7870 which the AMD 7970M is based on:

 

Cloud did you find something saying 680m will be coming from 670??? Thanks man! Great news

 

Nope, nothing official are saying that 670 = GTX 680M.
But to be fair, neither happend to 580M or 7970M.

GTX 660 Ti looks too weak to be the 680M, the memory bus doesn`t fit with the speculations. If 670 = 150W, then 660 Ti will be, maybe 130W. I don`t see Nvidia going that route, unless they feel confident that it will be enough to compete with 7970M. But then again it could maybe happen?

Based on the Vantage scores I shure hope that 680M will be based on 670. But like I said, pure speculations from my part.

 

Those Vantage scores are fishy. P runs are in 1280x1024 arent they? No wonder 1280x720 would boost them.

All in all seems to be the above the GTX580 and the rival of the HD7950. The GTX670 is not meant to be the competitor of the HD7870 unless they priced it accordingly, which would make the GTX680 a bad value haha.

But they definitely could make the GTX670 a GTX680m. The GTX660 should be the competitor of the HD7870 and if current newer rumors of specs are right, performance should still favor the nvidia card and easily translate nearly 1:1 to the mobile segment with little sacrifices.

 

It isn't as weak as you might think. Specially since Nvidia is using super highly clocked GDDR5 unlike AMD so they wouldn't even have problems using 192bit bus to match the speed. Additionally, 1k+ Cuda cores are more than enough to take on the 1280 GCN cores. When the first rumours spawn about 768 cores, those were far too few and weak, but now? I'd say they could totally translate the GTX660 directly to mobile without sacrificing performance. similar to Hd7870 transition with only a small downclock.

And performance should be right up there 10% or so higher than HD7970m

 

I don`t know if the P scores is legit, but the Extreme shurely is, and based on that the 670 is 25% faster than 7870.

Yeah you could be right though, 670 may be competing against 7950 maybe? If so, then by all freakin means, make a 680M out of this Nvidia. Maybe make whatever is replacing the 570M out of the 660 Ti. Man that would have been awesome.

 

Was discussed here somewhat: http://forum.notebookreview.com/win...supports-amd-radeon-hd-7970m.html#post8489163

 

I could kill for a 670 based 680m but yeah, looks like a long shot, hope is the source of spirit though!

 

Yeah, I mean look at availale products. GTX680 being highest end single GPU solution and the competitor is the HD7970.

HD7950/HD7870/HD7850 are unconstested

GTX670 could totally "fight" and shame the HD7870, but it would need to be in similar price, which is a huge delta from the 500dlrs of the GX680, thus GTX670 would be the card to get, and GTX680 would be DOA.

I say the GTX670 is going to be above HD7950 but below HD7970, and the GTX660 will be between HD7870 and HD7950.

The GTX660 will still be very powerful. It could be far more balanced, similar to HD7870 which is a superbly balanced GPU. I'm not sure what would they need to cut down in the GTX670 to keep the TDP in 100w. the HD7870 got a downclock and downvoltage but it was already at 140w to begin with, we don't know how the Cuda cores scale in that sense. 384 cores at 830 clocks are already 45w or so, triple the cuda cores, twice or so ROPs, texture units etc more etc... you can imagine reaching 100w TDP at high clockspeed.

Maybe a high clock GTX660 would beat down or match a GTX670 cut down, lets see which one gets to be on the 680m! Rest assured, they will vote for the one that beats AMD hahaha

 

670 = a cut down/defective GK104, not a new core.
This is analogous to a 7950, not a Pitcairn core.

 

All that matters is what Nvidia can make work within power and heat requirements for a laptop. Kepler is significantly better at potency/power than previous generations of Nvidia GPUs.

It may be feasible to snip down a desktop 670, but everyone's guess is the fabled 660Ti will be the 680m eventually. Still the desktop 670 in a laptop would be amazing.

Either way, the 7970m will still be an amazing price/performance choice as Nvidia will most likely charge blood for their 680m.

 

And now they have tested the GTX 670 with 3DMark11. 11% better score in "Performance" preset and 33% better score in "Extreme" preset. Average performance over the 7870 is 22%. It increase the lead in 1080p with settings cramped up, just like it did in Vantage.

Everything combined the 670 is 20% better than 7870 while sharing the same TDP. Compared to 7950, the 670 is 12.5% better while having 50W less TDP. 7950 is 200W while 670 is 150W.

Looks to me as if the GTX 660 Ti won`t be far away from 7950, which means that our 680M could perhaps in worse case scenario be a downclocked 7950 if 660Ti is 12.5% slower than 670 lol

 

Anyone seen this yet?:


According to " NVIDIA Radically Reduces GeForce GTX 670 Board Size - Bright Side Of News*" , it's the GTX 670's PCB.

 

Yeah lol, so small. I see a lot of people complaining about the size. Wonder if Nvidia did this to save cost to compete against AMD?

 

Any Cinebench benchmarks already?

 

Why would anyone complain about the size?

 

yeah its crazy,the 670s fan is completely off the pcb ^^ looks like nvidia is being extremely creative this year@kepler, turbo boost, energy consumption, reduced microlags(multi-gpu), automatic online game spec selection and now extremely shortened pcbs^^

Don`t ask me, I have no idea. Perhaps they want a behemoth of a card to reflect performance? idk

 

HALLELUJAH!!! 670 IS COMING TO LAPTOPS!! I am so happy, +rep you so much 5482741 (will rep in 24 hours )

Trust me Cloud, they did it to fit inside a lappy! it is coming, I am a believer now!

 

Hah, it was a midrange chip to begin with, a monster of one to be sure, but still a mid range one

Where is the source on it being a notebook chip?

 

Dont get your hopes too high yet

Anyone got any hint on release date? Not 7970M + 4 months please. Not again...

 

Well if it's GTX660 based it could be 6 months lol. I guess we will see.

 

Yeah graz, that would have been totally sick.

I`m hoping
690M 100W = 670
680M 80W (successor of 570M) = 660 Ti

 

675M = 580M, we already know that.

We COULD see a 680M and 685M, but if they intended that I think they would have done 570M -> 665M, 580M -> 670M.

 

OH darn I forgot. Ok lets call it 680M while 670 = 685M/690M

 

Nvidia's core strat is not as clear as amds at this point so its all pure speculation.

 

PLEASE let the GTX 670 end up as GTX 680M/690M

It is faster than 7970 and completely crush the 7950. LOL
I even think the GTX 660 Ti will be about equal to 7950 if not slightly faster

Here is the first review of it:
NVIDIA GEFORCE GTX 670 2GB Video Card Performance Preview - Benchmarks - Test System Setup and Specifications :: TweakTown USA Edition

 

Yes. But the fact that it consumes more power than HD7970 and near 50W more than reference Hd7870 means, than they will have to cut this card powerdraw about half to get 100W TDP GTX680M. This 150W TDP claim for this card is complite joke.
75W TDP of GT660M makes more and more sence now...
They pretty much need to pull rabit out of the hat, to beat HD7970M with this, at the same power consumption. Im not sure they are up for this.
