Nvidia GTX 680MX?

Will this be available in other laptops eventually? Or proprietary to Apple and the new iMacs?

You can get to the Nvidia page by googling "nvidia gtx 680mx" GeForce GTX 680MX | GeForce
but once you're there, clicking on the 680M makes the 680MX's link disappear from the sidebar: GeForce GTX 680M | GeForce

if we compare the specs we see the following: http://i291.photobucket.com/albums/ll312/xX_Ace_of_Spades_Xx/gtx680mx_zps5d545bdd.png


I ran 3DMark11 with my 680M (so, results may vary) and the latest 302.97 drivers from Nvidia. These are the results I got:
719 core / 1800 memory (stock clocks): 6214 - NVIDIA GeForce GTX 680M video card benchmark result - Intel Core i7-3720QM Processor,CLEVO P15xEMx score: P6214 3DMarks
854 core / 2000 memory (stable OC): 7129 - NVIDIA GeForce GTX 680M video card benchmark result - Intel Core i7-3720QM Processor,CLEVO P15xEMx score: P7129 3DMarks
854 core / 2200 memory (stable OC): 7112 - NVIDIA GeForce GTX 680M video card benchmark result - Intel Core i7-3720QM Processor,CLEVO P15xEMx score: P7112 3DMarks
823 core / 2500 memory (matching texture fill rate + memory bandwidth): 7027 - NVIDIA GeForce GTX 680M video card benchmark result - Intel Core i7-3720QM Processor,CLEVO P15xEMx score: P7027 3DMarks

Now, the full GK104 has 128 TMUs instead of the 112 on a GTX 670, meaning that to achieve 92.2GT/s, the core clock is 719MHz. This is the same as the stock clock for the current GTX 680M. According to MSI Afterburner's graphs, the stock voltage seems to be enough to keep the memory on a 680M right now even at 2500MHz. If the cores on this new GTX 680MX can overclock even just the +135 we're allowed on the stock BIOS with the current 680M, I think the 680MX could be a potential 15%+ performance increase from the GTX 680M.

I tested the 680M with the same clocks as my last test (823 core / 2500 memory) and got 7022 3DMarks - NVIDIA GeForce GTX 680M video card benchmark result - Intel Core i7-3720QM Processor,CLEVO P15xEMx score: P7022 3DMarks This time I used Saltius's modded vBIOS to allow 1.037V, so the GPU is definitely getting enough power. 7k stock 680MX score would be really impressive, a solid 13% improvement just by adding cores and increasing the memory bandwidth.

 

Oh god, something based on a desktop 680?

Glad that I held back on the 680M

 

it looks very interesting

 

I'm doing a couple runs of 3DMark11 to try and extrapolate what kinds of scores we might expect at stock speeds. I know the 680MX has more CUDA cores, but I can match the texture fill rates and memory bandwidth at stock voltage.

Speaking of memory bandwidth, if they don't change the cards, I doubt these 680MX will OC well at all. The Samsung RAM modules on them are only rated at 1250MHz, and from what I've read they don't like to go over that.

 

this explains two things: why the 680M overclocks so well and why you should never trust corporate america.

 

So it's better to buy a 680M instead of the 680MX if nvidia uses the same PCB for both?

 

Probably a different pcb if more cuda cores no? Means new offering from AMD soon too :hi2: ?

 

Interesting... I bet they're going to jack the price up though. It would be cool if it meant the 680m got a price reduction though.

 

They will probably keep the 680M's price

And price the 680MX at about 800USD /: lol

 

I updated the first post with a run of 3DMark11 with my (yours may be different) 680M running at a couple different speeds to show how things compare, all at stock voltage.

 

lol yeah, you're probably right.

cool, thanks for showing us the comparison. where did you see that the 680mx would be available with an apple product? didn't think they produced anything with that powerful of a gpu.

Could just be a typo, but by a simple google search I found this site selling a gt60 with a gtx680mx.

I know the site is one of those generic whole-sale sites, but for me they are generally right in predicting specifications.

 

wow, that's interesting. powerful mobile gpus in an all-in-one mac. isn't the 680m 4gb? is there a 2gb version also? just odd that the 680mx is 2gb when the 680m is 4.

 

Some gtx 680ms are 4gb, while some are 2gb. I believe that only the MSI made GTX680m has 4gb of vram, while other versions such as ASUS' have 2gb vram.

 

The Sager/Clevo version has 4gb, that's the one I'm most familiar with. The 675mx also has 4gb.

 

The most I've ever been able to load the memory up was 2.2GB in Skyrim with all the biggest texture mods I could find and crazy huge stuff like that on every object in the game.

I just flashed my 680M with the Saltius 1.037V vBIOS to see if the results would be any different and nope, at the same 92.2GT/s and 160GB/s memory bandwidth I got 7022, so I'll be updating the first post with this info shortly.

Hopefully, this 680MX also runs really cool and can overclock, but that's definitely going to require some faster RAM inboard.

 

wow, a dekstop gtx680 cuda core amount inside a laptop. well,the price is still the main concern for me though.

They fit the full gtx 680 into a notebook chip? Wow... Did not expect that.

 

The Card in the iMac will moving 2560x1440 pixel. So the 2GB on the newest stuff with maxed out settings will be a bottleneck. Btw Mac's aren't for gamers...

 

HOLY CRAP.

Ladies and gentlemen, soon we have 1536 CUDA cores on a mobile chip. A real downclocked GTX 680.A full GK104.

Mother of God.

 

Could this be one reason why the 680s are so hard to find for a descent price?

Nvidia has been making these instead of the 680's.

 

I see what nVIDIA did there... I'll just stick to the 680M

I expect the price to blow out of the roof haha

 

We might see a price reduction for GTX 680M when this GPU enter the market.

After all, GTX 680M and GTX 680MX is the exact same chip. Maybe this is a sign that the yields at TSMC is so good now that they don`t have to throw away so much chips because the cores are damaged and release them as GTX 680M. They can safely bin everything they produce and release a chip with fully 1536 cores.

Unfortunately this 680MX is going inside the Apple iMac 27 inch, and since Apple is so huge, they will probably take away everything and leave nothing for us

 

Not sure a bunch of customers will order a 680mx.

 

Keep in mind everybody the difference in specs between the 680m and 680mx is basically exactly the same as the desktop 670 and 680. Between the desktop 670 and 680 the difference was a few hundred points in 3DMark11 and sometimes the 670 actually came out on top in FPS. The 670 was also a lot cooler and OCed much better. There were people that sold 680's to go to 670's. I am sure the 680mx will be great and all, but it isn't a revolution. It probably won't OC as well and it likely will not be faster than a 680m with a safe OC on stock voltage.

This is almost certainly done in anticipation of AMD launching a 7990m, but I would not expect the 680mx to be much of an upgrade from a 680m. Just the constant improvement of technology. Plus, it will still be several months. We have known about the 675mx for a long time and as far as I know no one has received one yet. It will probably be 2013 before any 680mx make it into notebooks.

Benchmark Results: 3DMark 11 : GeForce GTX 670 2 GB Review: Is It Already Time To Forget GTX 680?

 

Well if the imac is shipping in december........

 

The 680 is 7% faster than 670 ( Click here).

But have you seen the memory bandwidth of the 680MX? Its 40% bigger than the 680M bandwidth. 160GB/s vs 115.2GB/s. 2500MHz vs 1800MHz.

I`m not shure if that will reflect so much on performance, but it looks like Nvidia is going on all gears with this GPU. For people who own 680M, its a pretty meh upgrade, but not for people who are in the market for a new GPU/notebook now. Who knows, price of the 680M might fall and the price for the 680MX might not be that bad, if yields are working like a charm at TSMC now. Its the same chip, they can afford to sell the 680MX at the same price as the 680M now.

But that remains to be seen. I have my doubts

 

Yea, the 7% was basically what I was saying, it is pointless. Plus, the 680mx is clocked the same as the 680m, while the desktop cards the 680 has a clock advantage. That suggests the difference will be even less than 7%. You can OC a 680m on stock voltage 15-20% with no real downside. If the 680mx overclocks just as well then it will still run faster but only by a few FPS.

I guess if benchmarks are extremely important to someone then the memory speed probably matters, but in OCing the 680m the memory speed doesn't seem to improve FPS.

I don't know, I think even if I was in the market today I probably wouldn't wait, it will probably be Jan or Feb 2013 before you could get this card in a notebook and there are so many great games over the next few months. Plus, by next year you are just that much closer to the 700 series and probably much larger performance increases.

 

I don`t disagree with you at all. We will see how this reflect on mobile GPUs. I`m still curious

 

It should be a nice bump as "king of the hill" but entirely unnecesary. We already know how the 680 vs 670 went down. A higher clocked 680m would have made more sense, but I can also understand the need to introduce hardware to make people scream in awe.

I use my 680m with 800/2200 clocks right now, for general use and gaming. I have barely a 6300 gpu score, so this new GPU should be slightly faster.

If this new 680mx brings the price of 680m down significantly, I will feel bad as I just recently got my machine hahahah

 

Same same, otherwise I only see the 680MX as a OC 680M.. and truth be told it probably is although I can only imagine if they did something magical to it

 

Omg how nvidia is going to explayne to the one's that bought the 680m for 800$ hot potato to them??a big shame to nvidia .....and to tell you the truth im nvidia fun,but that kind of BS prices is a big joke for mobiles gpu's!!!!!!!!

 

You should try 850/stock memory. With those settings I get 6800-7000 graphics score on stock voltage.

 

What Im curious to see is if the 680MX can overclock better than 680M. Have we reached the max power consumption the MXM can deliver on the 680M OC? Same with thermals, does it become too hot when overclocking?

Also, what is the purpose of having a 40% wider memory bus than 680M if the GPU only can deliver 5% more pixels.
Nvidia can`t just put it there just for fun right? It got to have a meaning....

 

I agree with this, improving just memory bandwidth does not yield that impressive of results.

I also am curious to see the temps on these cards, and their ability to OC. If they are already maxed out, and I assume will cost more than a 680M, I dont see the point in buying one.

 

I feel sorry for Nvidia users
7990m and 680mx will be faster than 680m which people paid a lot for to get.

I'll upgrade to 7990m at the cost of 100-200$ max after selling 7970m as usual
My problem with nvidia is that 680m prices will drop a lot soon and they will ask a lot for 680mx being the fastest and best.

Will be interesting to watch MX Benchmarks and i believe the GPU should be available very soon (like in 1 month) duo apple + Windows 8 launch

 

i dont think that the 680mx will a lot power than 680m,only by 10%or 15%.
and it doesnt worth to sell the 680m to get 680mx.....
my opinion....
these are strategys of companys of make more money.....

 

Same thing can be said about 7970m vs 680m, many people are willing to pay much more for that extra 3% let alone 10-15%
Yes some do pay more for drivers cuda etc but there are a lot of people would take 7970m over gtx 680m if it was a little faster even if it did cost more.

And i just checked alienware, they did drop the price of 680m a bit (by 50$)

I personally believe from the specs that 680MX will be around 20% faster

 

Try 5%, it is just like the jump between desktop 670 and 680 except without a clock advantage. Memory bandwidth really does not improve game performance at all currently. If the 680mx does not overclock as well, which is totally possible with it requiring more power and perhaps running hotter, it could easily be slower than an OC 680m.

 

I don't think they would release a GPU that much later with merely 5% boost unless they plan to release GTX685m 2 months later to compete with 7990m
7990m or even 8970m is not that far away.

 

We will have to see, but like I said it matches the specs of the desktop space, with the 680m being a 670 desktop and the 680mx being a 680 desktop.

On the desktop cards there is a 7% difference, without the clock advantage the 680 desktop has mobile will be even closer. I am sure at stock the 680mx will be faster than stock 680m, but it isn't a revolution or anything. If the 680mx doesn't OC as well then it will be in trouble. The 680m can OC 20+% easily, and with overvolt it can get insane simply because it has a lot of thermal and power draw headroom. Stuffing more cuda cores and such into the 680mx may significantly reduce the ability to safely OC, might end up with another 580m/675m situation where OCing tends to kill cards.

 

What's with all of the 7990M talk? I though we all agreed there definitely wouldn't be one, with the 7970M topping out the desktop 7800 series.

 

i think it will be like 580m/675m or at least 10%-15% defference.
nvidia likes those scenarios.

 

MORE MONEY!!! MORE MONEY!!! Nvidia has deemed, forking over $800 for the 680M wasn't enough. It's Apple time. Time to upgrade to the new 680MX, you have to have it. Get out your wallet. Scream, NVIDIA TAKE MY MONEY. It's Nvidia's new Apple beta program. And it's going to be a smash hit. All 680M owners, get out your wallets and get the latest and the best, 680MX. While at it, upgrade your iPhone 5 to an iPhone 5 just for the hell of it.

Nvidia should just come out and do it. Send out a massive email, do a massive marketing campaign. Call it, the Steve Jobs Hand Over Your Wallet beta program. It's new, It's Shiny, It's Apple, No it's Nvidia, maybe it's both! Doesn't matter, just get out your wallet and give me your money!

Of course Nvidia will combine with Apple to resurrect Billy Mays to voice this campaign.

 

Someone seems a little agitated? If people can afford it, who cares. I like to think of myself as an enthusiast so I will probably end up getting one lol. Hell I already have two 680m's for one laptop. One's being used and the other is a backup.

 

Well some people spent money smart,and some........they throw money in to the sink........because THEY HAVE TO!!!!

 

I think its good that Apple keep pushing Nvidia. They got a pretty nice GT 650M in their notebooks far away from the original specs from Nvidia

Please don`t go there.

 

Could it be that it's over a 100W chip and wouldn't work in an MXM form factor? Apple is king of proprietary so it wouldn't surprise me a bit that it's unique for iMac only.

Plus it's only ~ 15% more CUDA cores (1536 vs 13544), and well, faster RAM too (2500 vs 1800). Although most 680m can run at about 2400MHz, so the difference in overall performance, depending on game of course, will likely be less than 10%.
