The AMD Radeon Pro 500 series powers a wide array of new Apple products, including the MacBook Pro and iMac. However, when it comes to performance, the GPUs in new iMac are a lot more powerful. We have the Radeon Pro 570, 575, and 580; these GPUs are integrated into the high-end 27-inch iMac with Retina 5K display.
The GPUs help deliver an exceptional performance, so we will be able to experience VR for the first time on a Mac. Users will also enjoy the accelerated performance with creative apps like Final Cut Pro, Adobe Premiere Pro, After Effects, and Photoshop.
We have some iMac configurations with some differences in specs like the CPU, GPU, and hard drive. Now, let’s compare the specs of the Radeon Pro 570, 575, and 580.
