Maximum supported memory differs from installed RAM. Unified or shared memory is not dedicated VRAM. TDP, base power and maximum power have different definitions and conditions. System measurements do not establish the performance of an isolated chip. Memory Parameter Value and conditions Memory bus 256 bit Source and conditions View source ↗
