Similar to this week's article of looking at the OpenGL performance from the GeForce 9800GTX through GeForce GTX 980 Ti and TITAN X in preparation for Pascal Linux testing ahead, today I am doing a similar comparison while looking at the OpenCL compute performance. For thirteen NVIDIA GeForce graphics cards from Fermi to Maxwell I ran a popular OpenCL benchmark while comparing not only the raw performance but also the performance-per-Watt.

While for years developers working on FreeBSD have been porting DRM/KMS driver changes from the Linux kernel over to their kernel, they have trailed greatly behind the mainline Linux kernel driver state due to the amount of changes they have been making to the driver when re-basing it against a new Linux kernel release. Now they are pursuing a new approach of using a compatibility layer where they hope to be able to more closely follow the upstream Linux DRM/KMS drivers...
