We've built and shown (at various roadmap talks) cross compiled versions of Octane for AMD GPUs, as well as Intel CPU (and yeah it's slower than a 650 M) and, more interestingly, a third target: Intel Integrated graphics (on the exact same chip as CPU). The iGPU is over 4x the speed of the 16x thread x86 CPU cores, but can also use system memory. It has been a challenge to ship these builds given that drivers (and platforms/OS) support for this to work is really not in a good place (all our AMD work doesn't port to Mac OS), but we'll focus on these platforms in the coming months. One thing we are adding in 3.09 that will leverage CPU cores, is for the AI denoiser to also have a high performance CPU fallback for Haswell/AVX2. While Denoising isn't perfect, it also can cut down crazy long render times for scenes that are really noisy - having CPU handle denoising while GPU renders might be a starting point to provide more value using the CPU. The other solution is to offset local GPU costs with cloud rendering, which already exists through ORC. It will be improved and integrated better and with smaller overhead through RNDR. Also, RNDR will pay out more than ETH mining, so consider that all these mining GPUs may end up helping Octane users in the end once RNDR decentralization kicks in.
