Apple M1 Pro 14-Core GPU vs Apple M3 Pro 18-Core GPU vs Apple M1 Max 32-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 Pro 18-Core GPU

The Apple M3 Pro 18-Core GPU is a self-designed graphics card in the Apple M3 Pro (with 12 CPU cores) and offers all eighteen cores available on the chip. The graphics card uses a new architecture and now offers dynamic caching, mesh shading and ray tracing acceleration.

The GPU can access up to 36 GB LPDDR5-6400 unified memory via a 192-bit memory bus (max 150 GBit/s). Thanks to dynamic caching, the GPU only reserves as much memory as is required.

The entire chip is manufactured in the current 3nm process (probably N3B) at TSMC.

Apple M1 Max 32-Core GPU

The Apple M1 Max 32-Core-GPU is an integrated graphics card by Apple offering all 32 cores in the M1 Max Chip. The 4,096 ALUs offer a theoretical performance of up to 10.4 Teraflops. 

The graphics card has no dedicated graphics memory but can use the fast LPDDR5-6400 unified memory with a 512 bit bus (up to 400 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 Max is manufactured in the modern 5nm process at TSMC and offers an excellent energy efficiency.
