The Apple M1 is manufactured in the modern 5nm process at TSMC and should offer an excellent energy efficiency. The peak performance of the high end variant is 2.6 teraflops and thanks to the unified memory architecture it should have fast access to the RAM.
According to Apple it is faster and more energy efficient as competing products (like the Tiger Lake Xe GPU). The Apple M1 GPU is an integrated graphics card offering 8 cores (1 deactivated core in the entry MacBook Air) designed by Apple and integrated in the Apple M1 SoC.
