Surface Book CPU and GPU Models?

Thank you for your interest in the Surface Book, you may find here some more information regarding your questions.

Check with NVIDIA.  Dig around their forums and news releases.  They are the makers of the GPU.  That unit is in the base unit (keyboard) and not available for use when you detach the tablet portion to use as a tablet.

Microsoft doesn't know what "technical details" are and you will never find anything in-depth from them.  You will have to dig around to the component makers to get those details.  The CPU series is rumored to be the "Skylake" series from Intel.  So, you will have to check with Intel for those specifications.

There may be no true comparison data to use.  However, in the demo, sure did run AutoCAD pretty good!!!!!!

That's not true. The Microsoft store stated already yesterday the CPU in the Book really is "Skylake": Processor 6th Gen Intel Core i5 or i7 (Microsoft Surface Book - 512GB / Intel Core i7). That tech spec pages data should be available before clicking pre-order.

The 'clipboard' screen of the Surface Book is 8mm, so the CPU won't have a big TDP. That leaves very few 6th gen i5's or i7's. The main feature where they differ is whether they have Iris graphics or not. And that's interesting to know, since it determines how the graphics may be limited without the keyboard attached.

Here's a link from the NVIDIA blog site: Visual Computing a Highlight of Surface Book, Microsoft’s First Laptop. A Maxwell SKU that's all it sais. Which doesn't say much. Did it have a die shrink since a year ago? 3TFLOP in 200W for a laptop. That's Maxwell in the 980M, according to pcper.com. Maybe its even 14nm 3D stuff? You get a like that performance x2 or that power use /2. Conservatively. At least if its 14nm 3D.

It's not really fair to not call Intel HD Graphics a GPU as the Microsoft Store does at some point. What else is it? It's not 'discrete', but it's very good for the power it uses. And Surface Book still has a battery...that artist work and gaming you do on the Surface Book, you better hurry finishing it quickly ;) Regardless of the above, really. Unless the cord is plugged in off course.

But the native resolution is 3000x2000, let's say 3K. That's still quite heavy for any graphics hardware.

It doesn't say which GPU model it is, but it does say 1GB of GDDR5 VRAM which is an inadequate amount so I won't be buying a Surface Book.

Thanks for the fact sheet! This does both provide more technical specifications, including naming the CPU as 6th generation ( here is Intel's factsheet: http://download.intel.com/newsroom/kits/core/6thgen/pdfs/6th\_Gen\_Intel\_Core-Intel\_Xeon\_Factsheet.pdf ).

To at least my own satisfaction, this roughly answers the CPU question, but it would still be nice to have an "equivalent to" of a current model. However, the GPU model question appears to remain wholly unanswered. I tried finding information on the nVidia forums but there doesn't seem to be an answer there (at least as of yesterday).

As you probably know, nVidia makes GPUs of a wide range of performance, from very slow and cheap to very fast and expensive, even on mobile GPUs, so some kind of information here seems necessary for such an expensive component.

I wonder why Microsoft would not release either model information, or "equivalent to" information (even approximate), for their flagship laptop. I personally have never bought a laptop before without knowing this information and I don't think I'm alone in this.
