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. Power Parameter Value and conditions Source-reported maximum GPU power 70 W Source and conditions View source ↗
