Apple M2 Pro and M2 Max

Apple (Hacker News, MacRumors, Reddit):

Apple today announced M2 Pro and M2 Max, two next-generation SoCs (systems on a chip) that take the breakthrough power-efficient performance of Apple silicon to new heights. M2 Pro scales up the architecture of M2 to deliver an up to 12-core CPU and up to 19-core GPU, together with up to 32GB of fast unified memory. M2 Max builds on the capabilities of M2 Pro, including an up to 38-core GPU, double the unified memory bandwidth, and up to 96GB of unified memory. Its industry-leading performance per watt makes it the world’s most powerful and power-efficient chip for a pro laptop. Both chips also feature enhanced custom technologies, including a faster 16-core Neural Engine and Apple’s powerful media engine.


Built using a second-generation 5-nanometer process technology, M2 Pro consists of 40 billion transistors — nearly 20 percent more than M1 Pro, and double the amount in M2.


With its powerful CPU, M2 Pro can compile code up to 25 percent faster than M1 Pro, and up to 2.5x faster than MacBook Pro with an Intel Core i9 processor.


Update (2023-01-18): Geekerwan (via Hacker News):

We designed our own battery test model and run it against windows laptops. And we also benchmarked them using SPEC CPU, as well as real-life performance test, and more.
