Apple M4 Pro (12 cores) vs Apple M3

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.

Apple M3

The Apple M3 is a system on a chip (SoC) from Apple for notebooks that was introduced in late 2023. It integrates a new 8-core CPU with 4 performance cores with up to 4.06 GHz and 4 efficiency cores running at up to 2.75 GHz. Apple claims that the CPU is up to 20% faster than in the old Apple M2 (3.5 GHz). 

Due to the higher clock speeds and architecture improvements, the processor performance is also significantly better than the M2 in benchmarks (see e.g. Geekbench below) and can keep up with the fastest CPUs in short single-core tests (like the Raptor Lake i9-13950HX).

The M3 also integrates a new graphics adapter with dynamic caching, mesh shading and ray tracing acceleration called Apple M3 10-Core GPU. According to Apple, it is 20% faster than the GPU in the M2. The chip integrates again 10 GPU cores, but the cheaper variant only offers 8 cores (e.g. in the entry iMac). Later in early 2025 Apple also introduced a 9-core variant in the new iPad Air models. Furthermore, the GPU only supports 2 displays (an additional 6K60 display to the internal one).

Both GPU and CPU can access the unified memory on the package together. It is still available in 8, 16 and 24 GB variants and offers the same 100 GB/s maximum bandwidth (unlike the Pro models that feature a reduced memory bandwidth). 

The integrated 16-core Neural Engine has also been revised and now offers 18 TOPS peak performance (versus 15.8 TOPS in the M2 but 35 TOPS in the new A17 Pro). The video engine now supports AV1 decoding in hardware. H.264, HEVC and ProRes (RAW) can still be decoded and encoded.

Unfortunately, the integrated wireless network module only supports Wi-Fi 6E (no Wi-Fi 7) and due to the support of only a single external monitor, the chip also has to make do with no Thunderbolt 4 (Thunderbolt 3 / USB 4 support only for up to 40 Gbit/s).

The chip is manufactured on the current 3nm TSMC process (N3B most likely) and contains 25 billion transistors (+25% vs. Apple M2). The 3nm process should also contribute to the excellent efficiency of the chip. Under load, the M3 CPU consumes approximately 20 Watt.
