In some instances, the M1 Max with 32 GPU cores has impressed thoroughly, and in others, not so much. On this occasion, a lead developer of the image editor Affinity Photo points out that Apple’s latest silicon beats the AMD Radeon Pro W6900X, which was the fastest GPU ever tested using the application and costs a whopping $6,000.

According to Andy Somerfield, his Twitter thread highlights that Affinity Photo has been optimizing its program ever since Apple announced the M1 and he wanted to see how far the M1 Max has come in performance. Affinity Photo has developed its own benchmark suite with which it measures this performance, and it runs best when a GPU can deliver high bandwidth and compute performance.
