Enhanced designs offer more processor cores and larger IGPs, along with a wider memory bus.
Back in the spring, Apple unveiled its M4 system chip, which focused on AI, and now its more serious variants have become available, labeled Pro and Max. Each chip is made on TSMC’s 3 nm node, including the N3E option.
It is easiest to outline the main parameters of the M4 system chips with a table, which we will do below (for the sake of transparency, we have also included the previous M4 models):
| Type | M4 (v1) |
M4 (v2) |
M4 (v3) |
M4 Pro (v1) |
M4 Pro (v2) |
M4 Max (v1) |
M4 Max (v2) |
|---|---|---|---|---|---|---|---|
| Processor architecture | ARMv9 | ||||||
| High performance Number of CPU cores |
4 | 3 | 4 | 8 | 10 | 10 | 12 |
| Energy efficient Number of CPU cores |
4 | 6 | 6 | 4 | 4 | 4 | 4 |
| Number of IGP multiprocessors | 8 | 10 | 10 | 16 | 20 | 32 | 40 |
| Neural Engine number of seeds |
16 | ||||||
| Memory bus | 128 bites (8×16 bit) |
256 bites (16×16 bit) |
384 bites (24×16 bit) |
512 bites (32×16 bit) |
|||
| Supported memory | LPDDR5X (7700 MHz) | LPDDR5X (8533 MHz) | |||||
| Memory bandwidth | 120 GB/s | 273 GB/s | 410 GB/s | 546 GB/s | |||
| Multimedia engine | 8K AV1 (decode only), H.264, H.265, ProRes, ProRes RAW | ||||||
| Production technology | 3 nm (TSMC) | ||||||
It can be seen from the table that there are several versions of the three system chips, which Apple does not indicate separately, but the core number of the components shows which configuration potential customers are dealing with.

The M4 Pro and Max bring the basic innovations of the M4, that is, the updated processor cores, the new IGP, the new memory controller, and the new NPU.
