    with the 660M being incompatible in the HM series (thx to mythlogic for testing that), i dont see a bright 680M future for my machine.... thx for nothing clevo! :mad:

    I had an Nvidia GT8600, it will most likely be the last Nvidia product I own IF I can help it. Any company that knowingly releases a faulty product without intentions of informing it's consumers or attempting a fix is a company not worthy of my money.

    Lets be honest here also, if AMD was incapable of producing a quality product they would not be able to last in this market. There is SO much scrutiny over performance and function that anything less than a stellar product is immediately eviscerated by reviews.

    yeah, really sucks... actually wanted to keep this machine for another 2-3 years. but now ill probably swap to a haswell laptop next year... and take a reaaaal good and long look at the AW, MSI, Asus and Samsung competition this time :mad: :rolleyes:

    I couldn't agree more, the reason that you see alot of people with AMD cards is because its the only viable option at this time. Were not going to pay more for 675M to get half the performance at stock clocks, that just makes no sense. I prefer Nvidia because of their UI and their drivers have always been good to me. But I could not see paying $150 more for 675M. I run a GTX 580 in my desktop and very happy with it. But as of now I'm also very happy with my 7970m in my laptop. The only reason that I would upgrade to a 680m would be if I started having major issues with the 7970m. As of now I can play all the games I want to on it at very good frame rates. No crashing or issues, battlefield 3, crysis, shift 2, etc all run great.

    Asus don't make crappy Laptops the only bad decision was putting a gtx470M on the G75

    that tablet looks good to bad is going to be annihilated by apple IOS based tablet :D

    Not crappy laptops, just overpriced and not really catering to enthusiasts anymore. Asus is focused on the lowest denominator. They don't care about the enthusiasts and reseller as much anymore, they want huge sales at NewEgg, Amazon, TigerDirect and BestBuy. It's just a different targeted audience.

    People who are shopping for laptops on Amazon, TigerDirect, NewEgg or BestBuy won't have a clue what a Clevo/Sager is and Alienware would be well beyond their budget. Asus pretty much has that target crowd to themselves, so business wise, it was a smart move.

    680M specs they list.
    Core Clock
    720MHz
    Cuda Cores 1344
    Memory Clock 1800MHz
    Memory Size 4GB
    Memory Interface 256-bit
    Memory Type GDDR5
    Direct X support DX 11
    MXM Support Yes, MXM 3.0, type B
    Cooling Dedicated Cooling System
    NVIDIA PhysX support Yes

    Don't even bother touching the core clock until you get that memory clock much higher, 900mhz is nothing for a card of this power.

    Also does that clock include turbo? Is there any room for turbo above that anyway?

    Could be a potent overclocker.

    interesting...this is what is listed at Eurocom:

    4GB GDDR5, NVIDIA GTX 6x0M; 768 CUDA 256BIT, N13E-GTX (GK104) Kepler (28nm); MXM 3.0b;100W

    The HM series was last yr's model. It was just recently replaced with the EM series. So people that bought these laptops as late as a few months ago are a little mad that they can't update to modern vid cards

    Mem clock of 1800 :eek: GDDR5. Thats 7200mhz effective lol. Thats not possible unless its some new type of GDDR5 chips on them.

    Nvidia cards usually get listed as DDR.

    So 1800 = real 900 = data 3600.

    With the core clocks reduced i'd say 25-30% slower than the 670 (which turbos up to over 1ghz regularly) but with such a slap to the memory clock (1.5ghz to 900mhz) I'd say 65-70% of the performance of the 670. But it could be really game dependant and I am not very confident with that prediction.

    Hopefully the mem will clock if that's the config otherwise you will be so bandwidth starved.

    Why would they put such slow RAM compared with the competition?

    Power consumption, just like the 480m.

    That or the imc got hit hard by the voltage reduction.

    probably to reduce heat and thus have more head room for additional cuda cores and core clock?

    One thing to watchbis 3dmark 11 p runs being pointless due to the low resolutions. Game perfomance at 1080p would be lower due to restricted bandwidth.

    The type of memory fitted could be SUPER important.

    So basically a severely dowclocked 4GB GTX 670...I can live with that! Bring on overvolting! Although I would have thought they would be using MXM 3.1 which supports PCIe 3.0 like the 7970m.

    And WHO told you guys that the 680M was a downclocked 670? ME
    WHO said that it was impossible and no way it could happen? 99% of you guys.

    The signs was there all along. 670 use less power than 560 TI which the 580M was based on. A downclocked 670 can be around 15% faster than 7970M I think

    So it running at 720MHz means that it 26%ish slower than GTX 670?

    HAHAHA, so AWESOME :D :D :cool: :cool: :cool:
    And a big whopping "I told you so" to all you AMD fanboys who said that nothing could ever beat Pitcairn or the 7970M.

    Performance over 7970M:
    (16%+18%+20%+19%+26%+17%+16%+8%)/8 = 17.5%

    GTX is around 18% faster than 7970M

    It is freaking 80% (!!!) faster than GTX 580M



    Watch that language!

    what we aren't taking into account is the severely limited bandwidth (if those posted specs are right...3.6ghz??). If the vram clocks up, then we will see the true power of this card. That number doesn't make sense at all. They are going to put 4gigs of vram in this card, but it is @ 3.6ghz?? weird

    you are right, time will tell

    The GDDR5 is not running at 3600MHz. That is wrong since it have a memory bandwidth of 115.2GB/s

    Yeah, I`m getting me one of these as soon as they are available. With the great Nvidia drivers, the Optimus that works and the way it seems to crush the 7970M, it is a no brainer for $250 premium in my opinion :)
    Now the question that remains is that if we can overclock this baby up to GTX 670 performance. (Not that I have any need for it though) :D

    It could be that the 4gb modules run hot, hence the downclocking. If that's true, I think nVidia would be best served going back to 2gb since there are virtually no games that need more than 2gb at 1080p. I think the memory clocks will end up being the same as what they usually have for mobile chips (around 1200mhz/4800mhz effective)

    Here you go

    New NVIDIA GeForce GTX 680M now available from ORIGIN PC

    There are several resellers that list the 680M with 2GB too. Rabook is one of them

    Origin lists it as 1800Mhz, which GPU-z will list as 900Mhz. I am running the same memory clocks in my 580m 1800Mhz as reported by Inspector and 900Mhz as reported by GPU-z, and have 115.2GBit/s bandwidth.

    ummm yeah... it says right there 1800 mhz mem clock which translates to 900 mhz real clock ^^

    It have an effective memory speed of 1800MHz :)

    I think it is time to post the two pics together and maybe bump them up incase someone haven`t seen them :p

    ok, simple math using this formula:

    bandwidth = Memory interface / 8 * memory clock * 2

    256bit / 8 * mem_clock * 2 = 115.2 gb/s

    mem_clock=1800mhz

    which means the memory IS running 900mhz...so 3.6ghz effective...which is very low by today's standards

    @Cloudfire, the GDDR5 speed is 900Mhz, that's an effective clock rate of 3600Mhz which is 115.2GBit/s bandwidth.

    Oh, ok sorry. Thought you just multiply the memory speed by 2. Now I know :)
