    Some german site have gotten hold of the 3DMark Vantage score of GTX 780M. It was tested along with upcoming Haswell 4900MQ inside the upcoming DevilTech Fragbook DTX (MSI)

    GTX 780M scored P29458 in Vantage
    NVIDIA GeForce GTX 780M - Notebookcheck.com Technik/FAQ

    So what does that mean in terms of power compared to GTX 680M? Well a GTX 680M along with 3720QM score P21657 in Vantage. 3720QM is clocked at 3.6GHz, 4900MQ 3.8GHz. 5% difference. And its Haswell. So lets say 15% faster than 3720QM. If you tested 680M with 4900MQ, you would have roughly gotten: P21657x1.15 = P24905.

    That means ladies and gentlemen that the GTX 780M is how much more powerful than 680M?
    P29458/24905= 1.18 = GTX 780M is roughly 18% faster than GTX 680M

    So whats new about 780M? We don`t know that yet but if I should guess, its a bump up in cores. 680M have 1344 cores, 780M will most likely have 1536 cores. (15% increase in cores = roughly 18% better performance :)) So I expect 780M to be a 1536 core GPU with the same speed like we have now on 680M, 720MHz.

    There is information about the upcoming Fragbook that have Haswell and 780M here if anyone want to read.

    Preoders start in May, shipping begins in June after Computex.

    Sorry about all the mess, hope its readable. Bye :)

    So basically a 680MX with GPU Boost 2.0

    Sounds good to me!

    Sounds like the 680MX, 1536 cores, 720MHz Core... just wonder what RAM speed is? 680mx is 2500MHz, 680m is 1800MHz. Guess they managed to get the 680mx in a 100W TDP more or less.

    18% vantage does not equate to 18% FPS improvement though. Plus that's 1280x1024 not 1080p which is the real tell tale sign of performance difference. I say total FPS improvement at 1080p will be less than 10% especially if vRAM speed is the same.

    Yeah, don't see myself throwing out my 680ms any time soon, but I'm glad to see that Nvidia is still making improvements, especially with the rumors that AMD will only be releasing rebrands this year (haven't been paying much attention lately, so I could be wrong about that.)

    If vram speed stays the same there won't be any performance difference. Not in games. The 680m is already heavily bottlenecked by the slow vram.

    BF3 shows this perfectly. The difference between the 675mx and the 680m should be around 60% but since they have the same vram speed the 680 only gets 25% more fps. The low bandwidth is choking the 680m alive. lol

    But it clearly shows that SLI 680Ms only score 15% higher. I doubt a CPU can make up for THAT difference.

    680m SLI only 15% higher than single 680m? Where do you see that. Look at my review here of the Sager NP9370 with SLI 680m @ stock (orange bar) vs single 680m @ stock (red bar), SLI on average is 60-70% over single 680m. BF3 is about 40% improvement in my testing. But BF3 is VERY CPU intensive. Faster quad core actually hexacore would be ideal. I guess the game runs 8 threads.
