> that Intel can't artificially hurt AMD performance (but it apparently has no obligation to support unique AMD optimizations either). As far as I understand it quite the opposite, it explicitly mentions that it may not apply "optimizations that are not unique to Intel" to other processors. It wont select the optimal code path unless the CPU vendor ID is set to GenuineIntel and fall back to the worst path your compile settings include.
