The standard M4 silicon features a 10-core CPU, with four performance cores and six efficiency cores and a 10-core GPU with support for hardware-accelerated mesh shading, 2x faster ray tracing acceleration for improved gaming experience.

And, M4 supports up to 32GB of unified memory and has higher memory bandwidth of 120GB/s. The display engine of the M4 family is enhanced to support two external displays in addition to a built-in display. And M4 now supports up to four Thunderbolt 4 ports, providing fast data transfer speeds and even more flexibility across peripherals.

Apple M4 Pro

M4 Pro features an up to 14-core CPU consisting of up to 10 performance cores and four efficiency cores. It’s up to 1.9x faster than the CPU of M1 Pro, and up to 2.1x faster than the latest AI PC chip.2 The GPU features up to 20 cores for graphics performance that is 2x that of M4, and up to 2.4x faster than the latest AI PC chip.

The new M4 Pro supports up to 64GB of fast unified memory and 273GB/s of memory bandwidth, which is a whopping 75 percent increase over M3 Pro and 2x the bandwidth of any AI PC chip.

This, combined with the faster Neural Engine of the M4 family, means on-device Apple Intelligence models run at blazing speed.

The M4 Pro also supports Thunderbolt 5 on Mac, delivering up to 120Gb/s data transfer speeds, which more than doubles the throughput of Thunderbolt 4.

This is the best option for professionals working on larger file sizes across AI, video, code bases, and more.
