Apple M4 16-core GPU vs Apple M4 20-core GPU
Apple M4 16-core GPU
Apple M4 20-core GPU
The Apple M4 GPU (20 cores) is an integrated graphics adapter designed by Apple that's built into the 14-core Apple M4 Pro SoC. It features 20 "cores" and has access to at least 24 GB of fast 273 GB/s LPDDR5x on-package RAM depending on the configuration. As is typical for graphics adapters released in 2024, it has hardware support for ray tracing as well as mesh shading and other modern technologies. It also 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.
Performance
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 iGPU portion of the 14-core M4 Pro consumes just slightly over 30 W according to monitoring software. With no load, it makes do with as little as 1 W to 3 W.
Just like the rest of the Apple M4 Pro chip, the integrated graphics adapter is manufactured on a "second generation 3 nm" TSMC process which is still cutting-edge as of late 2024.
