Advantages of AMD Radeon VII

Much newer (7 February 2019 vs 30 June 2016)

Cheaper ($89 vs $180)

Wider memory bus (4096 vs 128 bit)

More pipelines (3840 vs 512)

Higher memory bandwidth (1024 vs 72 GB/s)

Finer manufacturing process technology (7 vs 28 nm)

Advantages of AMD Radeon R7 450 OEM

Lower power consumption (65W vs 295W), meaning that the rival with higher TDP might require a better cooler or other thermal solution.
