Apple M1 Pro 14-Core GPU vs Apple M3 Max 30-Core GPU

Apple M1 Pro 14-Core GPU

The Apple M1 Pro 14-Core-GPU is an integrated graphics card by Apple offering 14 of the 16 cores in the M1 Pro Chip. The 1792 ALUs offer a theoretical performance of up to 4.6 Teraflops (16 core variant with 2048 ALUs offers 5.3 Teraflops). 

The graphics card has no dedicated graphics memory but can use the fast LPDDR5-6400 unified memory with a 256 bit bus (up to 200 GBit/s).

The GPU clocks between 389 and 1296 MHz and offers no short term boost (389, 486, 648, 778, 972, 1296 MHz steps according to Powermetrics). The GPU is intended to use Apple Metal 2 API and could still be based on the older PowerVR architectures (last used in the Apple A10).

The Apple M1 Pro is manufactured in the modern 5nm process at TSMC and offers an excellent energy efficiency. According to the internal sensors, the GPU uses 15 Watt under full load.

Apple M3 Max 30-Core GPU

The Apple M3 Max 30-Core GPU is a self-designed graphics card in the Apple M3 SoC and offers 30 of the 40 cores that are included in the chip. According to Apple, the GPU uses a new architecture and now offers dynamic caching, mesh shading and ray tracing acceleration.

The graphics card can access up to 96 GB LPDDR5-6400 unified memory via a 512 bit memory bus (max 400 GBit/s). Thanks to dynamic caching, the GPU only reserves as much memory as is required.

Since the SoC is manufactured in the current 3nm (probably N3B) at TSMC.
