AMD Radeon Pro 555
The AMD Radeon Pro 555 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 2017 model with Kaby Lake) and is the performance is similar to the Radeon Pro 455 in the mid-tier MBP15 from 2016. The Polaris 21 chip is produced in a 14nm FinFET process and is the smaller Polaris chip. With a core clock of 855 MHz and 768 shaders, the Radeon Pro 555 offers the same specs as the previous Radeon Pro 455.
The Radeon Pro 555 is shipped with just 2 GB GDDR5 video memory, which could be insufficient for games. 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 455.
