Apple M4 (8 cores) vs Apple M4 Pro (14 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 (14 cores)

The 14-core Apple M4 Pro is a powerful ARM architecture processor (SoC) for laptops and mini-PCs that debuted in Sep 2024. It features 10 performance CPU cores running at up to 4.5 GHz along with 4 efficient cores running at up to 2.6 GHz. The 20-core M4 GPU and at least 24 GB of fast 273 GB/s LPDDR5x on-package memory depending on the configuration are included as well, as is USB 4 and Thunderbolt 5 support.

The built-in 16 core neural engine (up to 38 TOPS) is found across the whole M4 chip family. Furthermore, all M4 processors are thought to be based on the ARM v9.4-A architecture to a certain degree.

Performance

In our testing, the M4 Pro delivered multi-thread benchmark scores very close to those of the 16-core M3 Max as well as the Intel Core i9-12950HX. Some small generation-to-generation improvement is obviously present but it's the new integrated graphics adapters that are the real stars of the show.

Graphics

The 20-core M4 GPU has hardware support for ray tracing as well as mesh shading and other modern technologies. It supports external displays with resolutions as high as "8K" and it can HW-decode a few popular video codecs such as h.264, h.265 and AV1.

Its gaming performance is at least as good as that of the GTX 1660 Ti Laptop. Please keep in mind that very few games have been compiled specifically for Apple silicon Macs meaning most titles have to be run via emulation layers. Some of them are displayed with visual artefacts as a result, or don't start at all.

• The Witcher 3 1080p Ultra = 53 fps (close to the GTX 1660 Ti Laptop)
• Baldur's Gate 3 1440p Ultra = 42 fps (close to the GeForce RTX 4050 Laptop)
• Cyberpunk 2077 2.1 Phantom Liberty 1080p Ultra = 40 fps (close to the GTX 1660 Ti Laptop)

Power consumption

When under heavy CPU and GPU load, the SoC briefly consumes around 80 W before settling at around 70 W later. With no load at all, it makes do with 2 W to 7 W. A single P-core of the chip eats around 6 W when under heavy load.

The 2nd generation 3 nm TSMC process the M4 Pro is built with delivers good power efficiency, as of late 2024.
