Apple adds one more chip to the M1 chip line. M1 Ultra is the part and should be the spearhead of this generation. Since the chip is usually too big to fit on the surface of the die, they came up with something special.
The M1 Max also has die-to-die technology that merges two dies together. This is called Ultra Fusion and it is said to provide 2.5 TB/s of bandwidth and have no latency problems.
114 trillion transistors are on the chip and it supports 128 GB of unified memory. 20 CPU cores (16 high-performance, 4 efficiency cores), the neural engine has 32 cores and the GPU has 64 cores. A monster. According to Apple, the performance per watt is at a leading level in the industry.
