AMD 7970m vs GTX 680m

I thought there were some issues with the 6990M cards?

Also, I had some real problems with a 5870 with a poorly fitting heatsink and high temperatures, not to mention drivers that made some games stutter severely. There are also some games that just don't work too well with AMD no matter what you do such as Arkham Asylum, SR3 (I'm sure there are others) and I found GTA IV to have a lot more stutter with AMD although that game may not count. Having said that, I would most likely get the 7970M but I am tempted by the Nvidia a little. It is nice to have choices.

 

At this point, is Enduro even comparable to Optimus? I know that when the 7970M was released there were some issues with Enduro, but are those resolved? Optimus is a more developed technology I believe, does this mean it recognizes 3d applications better or what exactly?

 

I recall reading there was a issue with Enduro sometime ago on these forums. Lost track of it though, was something related to the fact that the card will not turn off and it would hinder some games FPS to the point you had to turn Enduro off to play it. :|

 

So that's really the case about the Optimus? If I get a 120Hz Screen and a 680m I can't use the dedicated graphics EVER?

 

Well sh*t I think I'll just go with the 60hz screen then

Well what is the battey life with light use with out switching to IGP

I prefer the M17xR4,but i have a little fear about the price with
the gtx 680m

If i take a Clevo i know now that i never be able to upgrade the GPU!
If i take a Clevo i can´t overclock the CPU!

 

now, that wasnt very nice was it? i thought this is a forum where everybody can voice their opinion. there's no need to be so defensive/harsh/offensive to others Cloud, even if their opinions are different from yours. thats just sounds very childish

 

You need to get caught up on current events. Hysterical and premature online petitions should be taken with a huge grain of salt.

 

I would be interested in a source for this. Neurons generally have a maximum AP firing rate of 1000 impulses/second. Upon introduction of a stimulus, retinal ganglion cells are often lower, <100 impulses/second. RGCs have strongly correlated firing. Without checking, I would guess horizontal and amacrine cells have something to do with distributing messages from photoreceptors. That suggests humans can see ~100 FPS, although it will vary by individual, and of course, while correlated, RGCs do not fire perfectly simultaneously, so it could be a little higher.

 

Human eye FPS is around 60 if you check medical sources. Just because the maximum speed neurons can transmit is faster doesn't mean that you see that speed. That being said, it does vary by person and I presume 70 FPS may look a little smoother than 60 FPS in certain circumstances, ie very fat movement. Even if a game plays faster than your eye can detect, you still get a little benefit from higher FPS, as they don't line up perfectly. I imagine there's a dropoff that may get quite steep, especially past 100fps (even 75 maybe? I know some people claim they can see flicker on 75hz monitors but personally I don't buy it)

 

That's the only place I get my info. That and my neurobiology textbook collection .

The literature has various numbers for firing rate for RGCs. In some, it is as low as 20 Hz. Looking at a few PNAS articles I have, it is as high as 85.

Edit: Should note, without light stimulus, the rate can be 5-10 Hz.

 

I wouldn't want to drag the thread too far off topic , but yeah the eye stuff really fascinates me. Up to 85 hz would explain those people complaining that even 75hz CRTs flicker.

About the title's cards.... Yeah... When can we expect Slickdude and others who have presumably ordered standalone 680Ms to get theirs in the mail? Same time the resellers begin shipping (end of June) or when?

 

The nVidia GTX 680M is not faster then the Radeon HD 7970M:

Optimus depend on your actual use. If you are plugged in a lot then you'd probably turn it off anyways so your games always use the discrete card. If you don't use windows it'll be off also. 120Hz screen currently is more specific to Nvidia only which I think is a bit unfair to ATI even if 3D is off. Some gamers don't want their card to clock down while gaming if it causes tearing and such. So it all depends on your use. I always have it turned off, mobile or plugged in. Just don't see myself using the computer for hours on battery because I'm probably going somewhere to plug in.
Get a tablet or phone with internet and call it a day.

 

Yes, its inside 2% in benchmarks. In some games it will lose, in some it will win.
Mostly its still slightly faster than 7970M, but the difference is small.
If someone belives the 15%+ on those NV leaked slides, then hes just an idiot or has no idea about what marketing tricks.

 

Could someone translate that? Even google translate, I just can't use chrome's auto translate from my phone.

 

Pretty much this.

 

Only reason to get the 680m instead of the 7970m is to have better driver support/updates. I hated AMD drivers but love their products.

 

the essentials:
MSI GT70 with GTX 680M and Intel Core i7-3920XM, Stock Settings:
Futuremark Vantage - P21952
Heaven Benchmark 3.0 Basic - 1661, average 65,9fps/min 37,1fps/max 133.2fps

Alienware M17x R4 with Radeon HD 7970M and Intel Core i7-3820QM, Stock Settings:
Futuremark Vantage - P22359
Heaven Benchmark 3.0 Basic - 1749, average 69,4fps/min 36,6fps/max 133.6fps

 

Thanks mate +rep. It's too bad they're synthetic and no game benchmarks, but perhaps in the next couple of days we'll see someone other than Nvidia posting numbers./.

 

Single GPU Vantage scores correlates very well to actual gaming performance though. Comparing its core clock to the desktop 670, the score should be higher so I think the low memory speed is definitely holding it back. If the memory can be overclocked easily, then it won't be a problem but it's strange why they're so low in the first place.

 

Some people are just very devoted, blindly devoted in this case.......but devoted none the less.

If you attempt to talk some sense into them or at least bring them back to levels of reality (LOL 15% ) they violently lash out at you as if you just insulted their mother.

That being said it seems as though I have just discovered the the front right side of my new 150EM is raised in relation to the other 3 corners ...........I must investigate this.

 

Hey hey no names. We've got to leave those fiery people with their heads stuck in the clouds alone. They're apt to become violent .

That being said... It would be cool if the $300 price increase got you something other than a green sticker as opposed to red. I wouldn't mind 20% or so increase.... *dream* Sadly yeah. It's probably not happening, especially looking at the numbers released so far.

 

Im sure that OC to OC results, the GTX680M has more potentsial. Its all about how efficent your notebook GPU cooler is.
But i still think that price difference is not worth going for 680M at the moment.
Unless your heart is green.

 

hmmm i dunno about the OC potential. seeing how low they clocked the vRAM, it couldve been to keep the gpu inside the 100W TDP and be able cram in the 1344 CUDA cores in order to beat AMD. if that indeed is true then i dont think the OC potential would be as high as AMD´s (approx. 20%)

 

factory clock and manual overclocking are totally different things.
680M has huge potentsial due being almost full GK104. Memory overclocking does not drastically increase heat generation.
Im sure that they kept as memory as low as it is for keeping it inside 100W envelope. I cant think of any other reason why to do so otherwise. Im sure they would have wanted to beat 7970M by bigger margin than they did.
Big question is what is the voltage of card GDDR5. If its turned very low then we could not get much OC from memory either. Despite its being GDDR5. Probably vmem is not adjustable by software.

 

Since it came up, here is an interesting read regarding human sight and frames per second.

I'm excited that the 680M has finally been unveiled, and am still waiting to see the performance compared to the 7970M from the community. Honestly, if it is 10% than the 7970M but costs $300 more, I am not interested.

What really dictates my choice of future GPU is whether or not it is compatible with my laptop. This whole HM GPU upgrade fiasco has me a little concerned, but I'm waiting it out to see what the truth really is. 680M or 7970M, I just want the next generation of performance in my machine, and I could care less either way if it is red or green. Price plays an important role, but compatibility is obviously the biggest factor here for me.

 

memory overclocking actually DOES increase heat drastically, much more actually than OCing the gpu core overclocked memory gets intensely hot and since heat is the major culprit when overclocking it doesnt matter if the gpu DOES have a huge headroom due to being an almost fully unlocked GK104, since its not gonna be stable due to the memory-produced heat

thus, ure kinda contradicting urself in ur statement: on one side u say that nvidia downclocked the memory to keep the card inside the 100W envelope, on the other hand u say its gonna have a huge OC headroom due to the GK104 nature. those two cancel each other out --> lots of heat = little overclocking headroom

cheers

 

oops, double post ^^

 

could 7970M or 680m compatible with p150hm

 

Sager tested a HD 7970m from the first batch they recieved, and it seems to work.

that's good news

 

hummm... could be, but then that would mean the clocks are set to 650 or so and boost up to 720. (pure speculation of course)

but over clocking the 680m is a bit different than the 580m.(if they follow desktop standards) they use power target / cpu and memory clock offset to over clock...

lets hope it's a bit more than a down clocked 670...considering the fastest 670 is 39.4k gpu while the 7970m is doing 41+k gpu in crossfire. 12.5k gpu in 3dmark11 while still beating the desktop 7970 and the 680, which was never before done.(as far as i can tell)

but all will be reviled soon enough i guess...

 

don't know if anyone has posted those numbers already but i guess they're quite interesting.



Those are desktop GPU-Numbers, but i guess the pros in here can do the math and predictions for the mobile versions
I'm not a pro with all this GPU-stuff, just have been following those threads to make my decision (ordered p150em + 7970M)

 

Is this recent? I heard so far testing showed that the 7970M wouldn't work on the HM series, or was that only the 170HM? Sorry there is so much confusion going on about this issue that it is hard to follow sometimes.

EDIT: Alright, I saw all the updates in the petition thread over in the Sager/Clevo forum. Looks like they are getting elbow deep into the situation and providing a lot of feedback to the community, so that is great. Now it is just a waiting game to see if the 7970M is compatible with my machine and LCD panel.

 

hard to say...since the desktop 7970 (more so the lightning version) is beating the 680 in almost all bench's.....and a lot of games at that.

 

No, im not contradicting at all. I didnt say that mem oc does not generae more heat. ofc it does. But not as much as GPU. Thats would be just riddiculus to claim. Not ever close to core power consumption.
If we would also considerably increase vMem, then it would be different story.
With my 9 years of overclocking history, i have to disagree with you here. Sorry.
GDDR5 doesnt even get warm at those speeds and does not need heatspreaders up to 1500ish mhz.
Nvidia probably found the best solution to downgrade memory clock instead of downclocking core even more than this.

 

Sooo... using this logic... everyone, to this day, was a complete idiot to have any feeling related to "hope" or "confidence" about something they supported? Huh... That makes sense right?

Call it what you want. Beta drivers only tell part of the story.

 

The 7970M is plug and play with 6970M equipped NP8170s, other than needing Sager's custom VBIOS.

 

It will be 720mhz base, 828mhz max turbo (Chip/system/game dependant)

 

Good news!

Any idea if they have created a custom vbios for the P150HM as well, and where to find it?

 

It's quite astounding how far we've come with mobile gpu's in such a short time.

I never would have believed a pc game can be played on max with a mobile processor, i really can't wait for my shiny new clevo to arrive though it is due on the 14th to the reseller

 

What beating? What margin? From what we know today, the Radeon HD 7970M is on par with the GTX 680M.

 

LoL. According to Cloudfire, its 15+% faster at minimum.
I belive, its a bit better, but i wouldnt claim anything until i see some legit reviews.

 

Should the 680M and 7970M be on a par (hypothetically speaking) would it be better to then order the M17x R4 with the 120hz screen rather than being limited to a 60hz screen as the 7970M configuration restricts you to only 60hz?

 

Sure?

Where are the 15%+ or even better? Ok, only two benchmarks, but...

 

Better if cash is not an issue.

 

Not really with the 120hz screen you can't switch to integrated graphics to save power which I was looking to to get the 120hz until I found out you can't switch to integrated graphics but I might get the 3d screen anyways

I don't plan on ever playing it without it being plugged in anyway, I require a laptop due to space restrictions.

Price isn't an issue so far as to say that I promised myself a new laptop once I graduated/finished university to I may as well splurge. I just thought forking out for the M18x was a bit excessive...even though I'd love CFX/SLI functionality.

Reason I asked is because obviously the 60hz screen cannot display anything over 60fps and also cannot display 24p blu-ray moves due to pulldown. With the 120hz wouldn't games look a lot better due to the ability to display more FPS? Or is there really no cause for concern.

 

Really? That is great to hear! Would I contact Sager directly, or get a hold of my reseller (XoticPC) regarding getting my hands on the proper VBIOS?
