Well there's a bunch of problems: 1) If your are going to completely rewrite your code for an accelerator you are liking going to use CUDA to target a MUCH better accelerator. 2) If you don't you are likely going to ignore the decent intel GPUs because astonishingly small number of the intel SKUs (let alone the non-intel) have a decent GPU. Try to find a regular product/laptop with a i5-5675c or i7-5775c in it for instance. 3) CUDA was available first and seems to have the lion share of the mindshare. OpenCL is a distant second. 4) Even if you have the right SKU, devices with said SKU are often not designed for heavy GPU use and will heavily thermally throttle. I've played this game hoping for a linux laptop with a non-crappy GPU and I didn't want to play games with nvidia feeding pixels through the intel GPU to get to the screen. Very few laptops have the Iris chips. The lenovo 721s has the iris 540, but they locked linux out with their broken BIOS that disables AHCI. The XPS 13 has it as an option, but you have to get the I7 and the 3200x1800 shiny/relective screen that halves your battery life. I did manage to buy an Iris 540 NUC, nice little machine and the GPU seems to keep up quite well for the light usage I've tried. Most web games, full screen 1080P movies, and minecraft.
