Open cl processor

Post by Ezearebalo » Tue Oct 02, 2018 3:51 am

Hi im searching some "new" processor. But i dont understand something. The cpu need to have open cl 2.0 capability to speed up renders ? Look the image, i7 and fx 6300 doesnt have it ? I should buy a brand new processor ? Thanks

No. LuxCore uses native C++ code for CPU devices, OpenCL is only used for GPUs.
Also, the integrated GPUs in modern CPUs are not really capable of running LuxCore.

As per my knowledge If you dump a clinfo application type of output against an Intel based OCL implementation, you'll see each core mapped to an OCL execution unit. The entire CPU will present itself as one OCL device. If you have a host thread active while kernels are active, a naive OCL runtime will gang schedule over the "Host" core.

What about the Vega graphics in AMD Ryzen 2XXXG Processors?
Has someone tested those?

Some of the past AMD APU were working fine but you have to check case by case to be sure.
