AMD Radeon Pro 555X vs Apple M1 8-Core GPU vs Apple M1 Max 24-Core GPU
AMD Radeon Pro 555X
► remove from comparisonThe AMD Radeon Pro 555X is a mobile graphics card based on the small Polaris 21 chip from AMD. It is available in the 15-inch Apple MacBook Pro (Mid 2018 model with Coffee Lake) and is the performance is similar to the old Radeon Pro 455 / 555. The difference is the slightly higher clock rate of 907 MHz versus 855 MHz (+6%) and the bigger graphics memory (4 GB versus 2 GB GDDR5). The Polaris 21 chip is produced in a 14nm FinFET process and is the smaller Polaris chip.
Both the performance and the power consumption are roughly on par with the Nvidia GeForce MX150 (laptop version of the GT 1030), which is also equipped with 2 GB GDDR5-VRAM.
More information about the Polaris architecture is available in our dedicated article. More benchmarks including gaming tests are listed on the dedicated page for the similarly powerful Radeon Pro 555 / Radeon Pro 455.
Apple M1 8-Core GPU
► remove from comparisonThe Apple M1 GPU is an integrated graphics card offering 8 cores (1 deactivated core in the entry MacBook Air) designed by Apple and integrated in the Apple M1 SoC. According to Apple it is faster and more energy efficient as competing products (like the Tiger Lake Xe GPU). The peak performance of the high end variant is 2.6 teraflops and thanks to the unified memory architecture it should have fast access to the RAM.
The Apple M1 is manufactured in the modern 5nm process at TSMC and should offer an excellent energy efficiency. According to internal tools, the M1 GPU uses under load approximately 10 Watt (11.5 Watt package power including the RAM).
Apple M1 Max 24-Core GPU
► remove from comparisonThe Apple M1 Max 24-Core-GPU is an integrated graphics card by Apple offering 24 of the 32 cores in the M1 Max Chip. The 3,072 ALUs offer a theoretical performance of up to 8 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.
