If you were wondering what the exact specs were on AMD’s Polaris-imbued Radeon Pro 400 series of graphics cards, recently announced to be the driving GPUs on the 15-inch MacBook Pro, you need not imagine what they could be anymore. Under their “Meet the Creators” program, the company has now published the specifications.
From top to bottom, the Radeon Pro 460 packs a total of 16 Compute Units (CUs), totalling 1024 stream processors, with peak theoretical performance of up to 1.86 teraflops. The middle of pack Radeon Pro 455 cuts those to 12 CUs and 768 stream processors, with peak theoretical performance of up to 1.3 teraflops. Finally, the lowest performer of the bunch is the Radeon Pro 450, which features only 10 CUs (640 stream processors) and has a theoretical bandwidth of up to 1 teraflops. Also of note is the fact that all three of the parts leverage the same 80 Gb/s memory bandwidth.
