“M1 Max is the largest chip Apple has ever built: 57 billion transistors and up to 64GB of fast unified memory.”
400GB/s of memory bandwidth on a laptop chip. Intel spent years shipping the same 14nm part with a new name, and Apple left for its own silicon. The press release is all superlatives, but the transistor count is real. The catch is that the 64GB is soldered on and priced like it.
