AMD Radeon Pro 555X

The 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 555Radeon Pro 455.
