That first bullet is a bit sketchy. Benchmarks, particularly geekbench, may have increased 6x, but that's being manipulated.

The GPUs have become much larger, so 6.8x is believable there, as is the inclusion of a matmul unit boosting AI.

The 2.x numbers are the most realistic, especially because they represent actual workloads.

Even the geekbench numbers from the link only ~doubled. For both single- and multi-core CPU and Metal GPU.
