Now packed with 25 billion transistors, five billion more than M2, the Apple M3 integrates the CPU, GPU, Neural Engine, I/O, and more into a single system on a chip (SoC). Now built with 3nm process technology, the Apple M3 8-core chip features four performance cores and four efficiency cores, which is up to 35 percent faster than M1 for CPU performance. The M3 also supports up to 24GB of unified memory.
With a 10-Core GPU, the M3 features Dynamic Caching, which allocates the use of local memory in hardware in real time. Dynamic Caching only uses the exact amount of memory needed for each task, which dramatically increases the average utilization of the GPU, resulting in significant performance increases for the most demanding pro apps and games. Hardware-accelerated ray tracing has arrived for the MacBook Air.
