[reddit] Surface Book dGPU specfications leaked from NVIDIA Control Panel: 384 CUDA cores @ 954Hz & 40GB/s memory bandwidth (via 64-bit bus @ 5010MHz), on PCIe 3.0 x4 - Page 8

According to the marketing team presenting the surface book, the tablet only has 1/4 of the battery in it, which should hit 3 hours out of the total 12 of "every day use".
They also stated that heavy use will be about 1.5-2 hours.
There is a vid on the surface book thread opened earlier about it.

I think GDDR5 memory that SB uses should make big difference

GDDR5 is huge. 30 to 50% performance improvements.

The CPUs are actually similar to those on the Macbook Pro, so the selling points are the ability to become a 13.5'' tablet (that I can't imagine being comfortable to hold), and a 940M driving a 3000x2000 screen? At least on the MBP you can have ideal scaling with 1280x800, which is a fairly common resolution, but games may not support 1500x1000 or 750x500.

I currently have a laptop with an old 555m (550m with faster GDDR5 RAM basically) and it plays modern games still at 768p without issue (I can play BF4 with decent settings, Elite: Dangerous no problem on high, easily LoL and any Source game) so this being generations newer and much faster should be able to handle today's games. The only issue would be resolution as at that high, it will bring that gpu to its knees.

You don't have to play games on native resolution. I have laptop with 1080p screen, and games don't look bad at all when I play 720p specially when I use AA

The surface book display is 3000x2000, and you could play games at 1500x1000 which should scale well.

Oh I know. But it is such an odd resolution that some games may not support. You could always play windowed 1080p, but then it will be like playing on a 10 or 11" screen.

While large, apparently the tablet only portion of the Surface Book is actually lighter than the Surface Pro 4. Weight rather than size typically dictates ease of use over a period of time.

I daily use a SP3, and it is an amazing piece of equipment. The SP4 looks to be about perfect with the new cover and the magnetic pen and real eraser. Love it! I really want to get my hands on this book just to check it out.

If its about the 940M mark then thats great for the size of the machine, Plus i believe it is fanless too so its actually really awesome.

I actually wish smaller laptops used something like the GTX 950M / 940M in general, something sub £700 but also light and thin, but i like my battery life too and while intels iGPU's are fairly decent these days but the drivers.... Oh god....
