  I've seen this happen so much at the Zabaware forum,  so many people with I want this I want that.  Lets say a person buys a Skylark and wants to make it as fast as possible, he says I want the cpu to spend as much time as possible on cpu related tasks and will buy a graphics card for say 200, to handle the graphics. 
  Since I believe Data has all the necessary software to monitor, and has all the hardware to run a test where we could see the difference in performance. 
  In reality I have 2 computers with 2 OS, is two OS necessary no, are 2 computers necessary no.  Have I wasted money in the past yes.

Here is a thought:

Keeping components close to each other speeds things up, we know this and Intel know it too, there is a reason they are putting the GPU on the CPU chip, it's much closer and quicker to communicate, no need to go round the houses through the PCIe bus to get to the graphics card. That is why the fastest booting PC's I have ever seen use the on chip GPU. The on chip GPU is also fully independent from the CPU and has no negative side effects that I can see.

Here is the chip layout, the GPU is independent from the CPU cores, far left on the image.

I don't pretend to understand all this, but it's surprising how the shorter distance gives you noticeable boot time speeds.

Data

Yes it's surprising but true, no drivers to send down the PCIe to communicate with the graphics card just all very close to the CPU. Its not a huge improvement but put a graphics card in and you can notice it takes a little longer to boot. No big deal but it's there.

Carl2

  That makes sense, and the Intel Graphics has a direct line to the video port I'd guess.  The problem I see is the CPU is now doing computing for the graphics.  Now I am wondering why the bios quick start up has not taken a piece of memory and stored necessary start info right in the CPU memory, if the clock still works it has power and should be able to keep the stored info for a quick start up.  I will not get into a dual boot at this time.

Not really, the GPU part of the CPU will do all the graphics tasks but none of cores will, leaving them free for everything else. If you put graphics card in then the GPU part of the CPU just sits there and does nothing.

Intel® Rapid Start only really works when waking the computer from a deep sleep, it doesn't work with a full boot from cold. At least that is how I understand it.

Data,
  Thanks for the info, the gpu does not rely on the cores to process video info.  I do believe I have found an exception, I just checked the Nvidia settings in control panel, I am asked to select the PhysX processor and have a choice of the CPU or the Nvidia.  Hals Haptek characters use PhysX and I'm pretty sure most games make use of some PhysX.
  " Intel® Rapid Start only really works when waking the computer from a deep sleep, it doesn't work with a full boot from cold."  That is how I understand it also which is new info to me since I thought it was for a cold boot.  What is done during sleep is transfer from active memory to the SSD an iso which is the opposite of what I was saying to conserve power.

Yes I used to have to install PhysX to run some older games, don't have to on modern games engines but yes it's an NVidia only technology, I use AMD graphics cards. I know you like Ultra Hal Carl2 but I have never had a problem running it on AMD cards, haven't played around with Hal for many years now though.  I'm sure any Skylake CPU could handle Hal with out to many problems. it isn't exactly CPU or GPU intensive, but I see your point.

Carl2

  I remember reading about having video cards being able to handle physics and I also remember the Haptek jiggey  female that has a .Phy file that contains the physics properties.  At Daz they are beginning to sell software to work with physical properties, also some software for body morphing if it encounters an object but I'm not sure if that is related.  Here is a link to one     http://www.daz3d.com/reality-4-daz-studio-edition
  I do remember seeing a vid of a game and while watching it I thought that must be using a Physics file for the movement of something swinging.  So is a video made while using scripting in say Daz studio and this video is played back on a regular video player.

Data

I know very little about Daz Studio if I'm honest, mainly concentrate on new hardware and Windows.

Both AMD and NVidia graphics cards can handle Physics these days but the software run on them needs to be able to utilise that technology, some software manufactures will tend to favour one over the other. Most modern game and 3D engines have their own Physics engine in so it wouldn't matter what make of card you have you would still be able to run it perfectly ok.   

Lets cut to the chase and bring it up to date if I may, DirectX 12 is where it's at these days and Skylake fully supports DX 12.

DX12 is only supported in windows 10, as we know :)

As far as I know today if Daz is using physics it would be for making videos and not real time like Haptek. So yes unless something new is on the horizon it would mean a regular video in a regular video player.

Freddy,
  Thanks for putting that in.  Quite a lot to all this, started with the Skylark CPU, got into the built in graphic, DX 12 and back to win 10.
Possibly some day this info will prove useful but I feel like I'm walking on secure footing if you know what I mean.

It can be tough keeping up with all the changes going on with computers and software. We are all learning as we go  8)

Freddy

Yep I agree with that, technology seems to change daily.

Data

4 more Skylake CPU's have hit the market, still no 6 or 8 core but I will keep us posted.
