AMD 7970m vs GTX 680m

China is where they most of the silicon so it ends up slipping into people with sticky gloves.

Edit:Skittles beat me to it (damn you T.T)

 

you just realize that now?

 

I've got 2 questions.
1)Is the 675M a good GPU? Meaning its solid and will last a while?
2)How much is the 7970M? If I were to get a laptop now since I need one, I'd get a cheap GPU and then swap it for the 7970M? Are we talking like $400?

 

1) It is yes, more than enough to play every game ont he market maxed out presets 1080p at 30+ FPS with the exception of Witcher 2 (ubersampling), Crysis 2 (poorly implimented DX11 and tesselation) and Metro 2033 (dx11 is demanding, just play it in dx9... look sbetter too...).

2) around 500$. I would recommend waiting for the 7970M and buying that in a laptop to save money.

 

Owners of these cards have provided you wPith the right numbers ffs, maybe take your blinkers off for 5 seconds so you dont make yourself look like an a** AGAIN.

 

Problem is I need the laptop in the next week or 2.

 

Well I might have stayed with a notebook despite switching to a desktop mainly for CPU reasons. It is important to an extent but since most of the arguments aren't very strong at all I'm not inclined to put in any more effort.

 

A couple of assumptions, but if nVidia were caught napping by the speed of the 7970m, might they have scrapped the card originally supposed to be the 680m, and be in the process of making the 685m to release as the 680m?

If so, will they be in position to counter the 7990, if/when it comes out, possibly q3/q4 this year?

 

if we compare to the desktop cards: as far as i know nvidia crushes amd in performance per watt therefore anything based on kepler will be better than anything based on GCN, per watt of course, and because the cards will have a 100w tdp its simple, the 680m will be better.

consider this, the gtx 670 was just released and it has a 170w tdp and the the old gtx 560ti(of which the 580m was based off of) had a 170w tdp. by this logic the 680m will be based on the gtx 670.

as we see in this anandtech review the gtx 670 destroy the HD 7870 in bf3 its 54% faster!

say what you will the nvidia card is going to crush the amd.

 

You must be blind. Because Perfomance per watt is NOT where Kepler shines over Pitcairn. Only GTX690 perfomance per watt is great.
Its overall perfomance in games where Kepler is a lot stronger.

NVIDIA GeForce GTX 670 2 GB Review | techPowerUp

This confirmes what i sayd earlier. Pitcairn perfomance per watt is way better near 100W envelope and Kepler perfomance per watt is on par at 200W envelope.
What comes to arhidecture. GGN is on par with Kepler on perfomance. Its all just the matter of optimizing it to the best. Nvidia has done wonderful job with its Dynamic overclocking ability. AMD has done good with its zero core power ability. Both are good.
Kepler core is just better optimized for games since GPGPU is cut out for enery savings and making perf per mm2 and perf per watt better.

 

Isn't GTX 690 dual core so 100W per core which completely invalidates your point?

 

Yes Pitcairn is very impressive and is the best performance/watt, but it doesn`t matter like said many times before. That chart is based on Average power consumption if you look at maximum, GTX 670 draws 18W more than 7870. But the 7870 is a complete joke performance wise compared to GTX 670. Nvidia had no problem taking away 50W before to match 580M and still beat the better performance/watt that 6990M was back then too, why should they have problem with taking away 44W this time and still crushing the 7970M since there is a huge gap between 670 and 7870 performance wise this time?

Nvidia have Kepler cards that beat everything AMD have out, both in performance and in power consumption, so your little chart means absolutely nothing. Go check out reviews of 670, 680 and 690. So no, GCN isn`t even remotely close to Kepler. Like said before, if Nvidia want, they can eat 7970M for breakfast

It shure is, Nvidia took away 80W and almost matched the 2x680 performance. That is impressive

 

well put good sir +rep

 

It all depends which side youre looking at it. Doesnt it?
Im trying to be realistic here, but looks like Greens just overran me again .
Well, we shall see in approx 4 months, if you take Korean forums as trueth.

 

4 more months? That would be so epic fail
I`ve heard that 680M is announced at Computex in Taipei in June and is ready for sale in July. But that was through a chinese forum.

Chinese vs Koreans. Who is right

 

690 has a 300W TDP = 150W per "card" Plus it gets power benefits by having a single power system.

 

question, but I'm not that tech savvy. And I've seen it come up time and again on here.

What is GPGU?

 

GPGPU, General Purpose Graphics Processing Unit.

 

Thanks Meaker!

 

Look at 670 and 680 then

Both perform about the same (Asus 670 beat the hell out of 680) yet it use +50watt less

These arguments talking as if nvidia can't cut watt usage are hilarious and shows how insecure some people are with their purchases, i already bought 7970m known it willbe beaten by nvidia but why should anyone cares? that's the circle of technology

Nvidia will release a better card and more expensive, AMD counter it with 8970m that is cheaper and faster months later and so on.

 

I'm surprised I have to point this out to people but you have to look at the power charts in a different way now.

If you look at the power consumption tests such as OCCT and furmark the card does not boost itself up to gaming clocks, it goes to stock.

If you compare that to gaming power consumption it therefore comes out lower.

In games it looks to draw 40-50W more than the 7870.

When it performs similar to the 680 it is using higher boost clocks and at the point consuming similar amounts of power.

 

Doesn`t matter. It was the exact same with the 6000 series vs 500 series too.

And I`m not going to debate about the power consumption again. That was shot down yesterday. Go read various reviews and you`ll see that the 670 is a perfect match for 680M

 

Wrong. For example, i havent purchace anything yet. And im not the fan of one or another. I have had both company cards in past and i love both of them equally.

Theres two sides of the story. There are arguments and counter arguments. Both are equally valid. Neither are more likely than other.
As i said before, speculations always depend on which side you are looking at them. In my previous posts i named both reasons why GTX680 may come as P7000 card and why it may not come as P7000 card.
However, i tend to think that it will not hit P7000, since there are more arguments indicating it.
I may very well be wrong.

 

The math is all there. P7000 is easily doable with a 680M

EDIT: Meh, I`m not wasting anymore time in this thread discussing with all you AMD naysayers.

 

I think it's possible too, but the figures you are using to get to that point are all wrong.

 

I was told september by Dell insiders...there could be some truth in this

 

That would be ironic if true...

 

Given that so far desktop 680M was pretty much "paper" card and almost impossible to buy, I am not surprised at all. Even if Nvidia will drop some chips into mobile market it won't be many and the price will be comparable to the US budget deficit.

 

Wow. You are such a Nvidia fanboy.

 

I'm sure he's a secret AMD fan. He is just pretending to love Nvidia and is bashing AMD so no one would figure that out (probably ashamed of his true love and passion)

 

I think nvidia thought of putting a low end gtx 680m to make the 780m look high end but once nvidia new the 7970m performance they panicked as they weren't expecting such performance. However whatever happens amd wins like they did with the 5000m series performance per watt wise.

 

Failure to read as usual, read what you quote people, i said "some" insecure people, clearly you are one and pretending you are not, you don't need to buy anything to post nonsense

All i see some posters here posting total nonsense and repeating again and again that watt=everything as if the formula have a fixed unchanged ratio, it was proven again and again that 670 perform the same as 680 with almost no real world different yet it use much less power

Lot of stupid arguments here really, get over it 680m might be a little faster, an overclocked 7970m is already near the 7k mark, 680m doing 7k after releasing much later is nothing special after we saw the 7970m numbers, yet some people here believe that 680m will be weaker than 7970m because to them watt is EVERYTHING as if they know for a fact that nvidia can not reduce the watts without losing much power, which historically proven false as i showed with the 670 and 680 case, never saw people who keep repeating nonsense after being corrected again and again, i guess they got some stock at AMD or working for them or something

 

Dont cry about people making arguments. If you dont like speculation then simply ignore this topic.

 

what do you mean almost lol? It is 100% completely impossible to buy...trust me, i've tried to get my hands on an es card. They just don't exist

EDIT: oops jaybee is right...i didn't see the word desktop. yes the gtx 680 is very hard to get right now. The ones that are available are swooped up immediately

 

@slick: i think he was talking about the desktop 680 not 680m ^^

its as simple as this:
Test: Nvidia GeForce GTX 670 (Seite 4) - ComputerBase

gtx 670 is about 20% stronger than hd 7870 while

Test: Nvidia GeForce GTX 670 (Seite 10) - ComputerBase

consuming not much more power than a 7870.So a little undervolting and downclocking will be enough to beat the 7970m as a gtx 680m.
So technically its no problem , its up to nvidia if they want to do it.
Its always the same Nvidia is the stronger one but Amd is much cheaper while beeing not much slower.

 

HSN21 is the only one in this forum that is able to comprehend and see the facts without his face buried up AMDs butt. And he have ordered a notebook with the 7970M. The rest of you are just angry because Nvidia might release a GPU that beats your "baby" (like some people here call their 7970M) by 20-25%.

Big kudos to you HSN21 (I would rep you again if I could). Rest of you people are really pathetic. From day 1 after 7970M was released you discredit every rumor about 680M and acted like AMD have done some sort of miracle that is impossible to do again. I don`t see why its such a big deal if 680M is what we think it will be. Its just a GPU. 1 year from now there will be something better anyways

 

The problem lies in the price, if Nvidia charges 250$+ more than 7970m for such performance then it´s a no go for a lot of people.

And by the way, don´t need to bash people if they think their GPU is a better purchase than the 680m, remember the 680m is vaporware atm.

 

There's an impressive amount of people who know next to nothing about graphics architecture making absurd claims here. The hardware is substantially more complicated then just looking at tdp usage and clocks, and adjusting on fixed percentages.

It's one thing to speculate and guess, but anything more then that is delving into BS territory. Anyone describing exactly how well the not yet revealed 680m will perform should be forced to add an asterisk to their post that reads: BTW this post is uses sources found only within my a**

 

I object, your Honor.

Allegation!

Child abuse and unsubstantiated speculation!

It's not. I just ordered 7970M and couldn't be happier. If speculating on something that may or may not happen makes someone happy - good for them...
[rorkas quietly retreats to his lair to check on delivery schedule of his new laptop]

 

Thread is rapidly turning to humor corner.

 

haha good one ^^ lets return some humor too this thread guys and downclock/undervolt the bashing otherwise well have some serious artifacts and BSODs on our hands

 

Thats the main problem here. We are talking about performance. If there is a chance GPU A beats GPU B, then it should be noted.

Yes, who knows, the 680M might cost a lot more than 7970M. I don`t disagree with that. That is a scenario that might happen. But as a side note, HD 7870 which the 7970M is based on cost $359. GTX 670 that the 680M might be based on, cost $399. That *may* reflect on mobile Kepler too this time around. One can always hope

GTX 670 is NOT vaporware btw. It is in stock everywhere. I think Nvidia is using damaged or chips that didn`t quite make it up to 680 standards. After all, the yields have been terrible for Nvidia. They probably have a huge stockpile of these chips.

@rorkas: I LOLed at your reply.
7970M is a very awesome GPU, there is no doubt about that. Its good that you are happy with it. But please let us continue with the rumor/prediction of 680M without getting shot down every single time by people owning the 7970M. After all, I am pretty shure very little people predicted the 45%++ performance over the 6990M.

 

LOL too nerdy for me.

 

If so, then wow, that sucks. And if its true, then we might see 680M be based on GTX 660 TI since its rumored to come around the same time. I don`t think many people want to wait 4 months more.

I hope its wrong. And I don`t get it to fit with everything that have happend the latest week. But who knows, anything is possible I guess

 

There shouldn't be any doubt whatosever that 680m will be faster than HD7970m.

Actually, as cloud states, we can even see a rather sizable jump too. Depends on how greedy nvidia gets.

However... I am worried by GTX670 vs GTX680. There was a what.. 12% decreese in hardware (cores) and slight decrease in texture units, plus a decrease in clock speeds. This only translated to about 7% performance loss?

That makes the GTX680 a rather bad deal, and it worries me how kepler scales upwards, rather than downwards. Also there is no real reason to even buy GTX680 anymore haha.

 

That does make me wonder why everyone assumed 670 automatically

But the points made by most of the people make more sense that a 670 scale down would be better. Still speculation though. For all we know nvidia could totally hate us and make a 640 scale down xD

 

Actually the 670 Asus version is better then the 680 both in stock and in overclock ! lol

 

There is an NVIDIA GPU technology conference taking place on the May 15th 2012. Any luck will GTX 680M be announced there???

 

I really don't understand nvidia's move with the 670. Its very possible that they are having such a hard time getting 680 yields that they came up with a 670 which they can deliver in volume (using faulty 680 silicon)

Its anyone's best guess right now..but industry people are saying Sept and this is all i have to go with right now. It has been stated several times on this thread that the 680m (or whatever it will be called) will be released in Sept...but with TSMC giving nvidia priority now, who knows if that speeds things up alot. If nvidia had to respin the silicon though, sept is not far fetched.

I'm sure the 680m will be faster than the 7970m...it would have to be. it would be suicide for them to release something that wasn't faster. This delay will undoubtedly give AMD time to come with an answer though. It will be very interesting to see how things progress by mid summer
