Apple M4 (8 cores) vs Apple M4 Pro (12 cores)

Apple M4 (8 cores)

The 8-core Apple M4 is an ARM architecture processor (SoC) that sports 8 CPU cores along with an 8-core GPU with hardware RT support and other modern features. A 16-core neural engine, USB 4 and Thunderbolt 4 are onboard, too.

The processor debuted in October 2024; it cuts down on the number of efficient cores but thankfully has the same 4 performance cores that its more powerful M4 brothers (non-Pro, non-Max) have. The P-cores probably run at 4.1 GHz or more; we don't have exact figures as of yet. The E-cores probably run at sub-3 GHz clock speeds.

This is the third member of the M4 (non-Pro, non-Max) family. It joins the 10-core M4 and the 9-core M4 that were unveiled several months before it.

The chip is believed to be based on the ARM v9.4-A microarchitecture to a certain extent. It comes with 16 GB or 24 GB of fast on-package LPDDR5x-7500 RAM; M3 processors had to be content with 6400 MT/s, for reference, while higher end M4 Pro and M4 Max processors get LPDDR5x-8533. It is not yet clear if this new chip is a 10-core M4 with several modules disabled, or if it's actually a new die that has fewer CPU and GPU cores by design.

Its performance is set to be very close to what Intel Lunar Lake processors such as the 256V deliver.

As far as power consumption is concerned, the SoC probably eats about 10 W when under long-term workloads. We'll update this section once we have one of the new Macs in for testing.

Apple M4 Pro (12 cores)

The Apple M4 Pro 12-Core CPU is a high-end SoC for laptops and mini PCs that was introduced in September 2024. It has 8 of the 10 powerful CPU cores running at up to 4.5 GHz and 4 efficient cores running at up to 2.6 GHz. The integrated 16-core GPU and at least 24 GB of fast LPDDR5x memory at 273 GB/s (depending on configuration) are included, as well as USB 4 and Thunderbolt 5 support.

The integrated neural engine with 16 cores (up to 38 TOPS) can be found in the entire M4 chip family. In addition, all M4 processors are assumed to be based on the ARM v9.4-A architecture to some degree.

The CPU performance when using all cores is similar to a AMD Ryzen AI 9 HX 370 (Cinebench R23 slightly faster on average). The modern Core Ultra 9 288V can be clearly outperformed. In terms of single-core performance, the M4 Pro scores very well and is on a par with the fastest Intel chips, such as the Core i9-14900HX. Interestingly enough, the M4 and the faster M4 Pro variant with 14 cores were 4-5% faster than the slimmed-down entry-level M4 Pro in Cinebench (Geekbench at the same level).

The power consumption during Cinebench 2024 Multi is around 40 Watt at the beginning (according to powermetrics) and then goes down to around 32 Watt (sustained). Combined with the GPU (Cinebench + Valley) the SoC can hit 47,5 Watt peak at the beginning, but then reduces its power draw to 31 Watt combined (22 W CPU + 9 W GPU).

The 3 nm TSMC process of the 2nd generation, with which the M4 Pro is manufactured, offers good energy efficiency.
