> If the company producing and selling the hardware is not giving the specs to their users, then it's their fault. AMD started releasing the low-level documentation for their GPUs in 2008, and although the FOSS drivers have benefitted stability-wise they're still lagging in API features and often offer less than half the performance of the proprietary counterparts. As far as I know we don't have a complete FOSS OpenCL 1.0 (ca. 2009) implementation for any ISA, nevermind newer versions or competitive performance. Unfortunately GPUs are so complex that specs alone don't guarantee good drivers.
