Hi!
So, have done a little crunching on this project here and there.
I have crunched with Intel hd 4000 a little, but am curious how the surface book will hold up and if I should even bother crunching with the intel hd graphics in the i5-6200U? I believe the performance of the GPU is in between or on par with a gtx 940 or 950m.
Right now I have it set to crunch WCG on the CPU. I'm asking around to see what would be the best project for the little guy. I'd like it to crunch for at least 10 to 12 hours a day. It's in a cooler room in the basement and GPU stressing with folding at home hasn't gotten the GPU over 65C but I'm not sure if it's being throttled.
The GPU is located in the dock for those that are new to the surface book. Really an ingenious design if I may say so.
I also have an older Sager laptop with a gtx 670M. Should I even bother trying with it?

Thanks!

I would expect throttling on the Surface Book as the current applications make both the CPU & GPU work very hard, and the cooling of the Surface Book , even with the unit on a rack & an external fan cooling it throttling is likely even with it's own active cooling.

As for crunching with the iGPU- generally the output of the iGPU doesn't offset the loss of output from the CPU that results when using the iGPU as they both share memory, cache & thermal limitations.
For low clocked, low core count CPUs with an integrated GPU using the iGPU can result in greater output. However for most current hich clocked, high core count CPUs, using the iGPU will often result in less output than not using & just letting the CPU do it's thing.
If your system has the discrete GPU using it may result in greater wok output, however thermal limitations may still come in to play.

Apparently there is a Performance Base(?) version which ha much better performance than the non Performance Base version.

Only way to see how well it will do would be to give it a go.

Got it crunching now. With the iGPU, CPU and discrete graphics card crunching the CPU seems to be throttled to 2.5 GHZ instead of 2.8, which is still utilizing turbo boost. Not sure what the Intel graphics should be sitting at but the Nvidia GPU (which I can't get a number on) is sitting around 980 mhz and I'm not sure what it's supposed to turbo to. According to HWiNFO it's using anywhere from 10 to 12 watts.

See how things go for a while, I personally suspect best output will be with the CPU & the Discrete GPU crunching, and the iGPU disabled from crunching.

Keep in mind it will take a while for the Manager to decide which application gives the best performance; and even then it can sometimes end up picking the wrong one depending on the work mix while it's determining which is best.

I tried this on my surface pro 4, the one that does not have the fancy graphics chip, and it worked OK for those BOINC projects that use the Intel gpu. It constantly ran hot even with tthrottle, and I removed it. Boinctasks is the only boinc type app I used on it now. Quick sync can be enabled on some surface Pros' and DvdFab's bluray copy program can use that for video conversions. Unfortunately, you need to buy a bluray portable player but the difference is minutes instead of hours.
