What's impressive about this is the high utilisation in this scenario. This is 900 GFLOPS out of a theoretical 2.1 TFLOPS on the M1. The Macbook that this site lists at a minimum comes with a 5500M which has a theoretical peak throughput of 4.4 TFLOPS, over twice that of the M1. Yet the M1 gets better almost 9 times better performance in this benchmark. Apparently. The issue is, though, we don't know whether this is actually about the architecture of the products or if the Safari WebGPU implementation is just not as well optimised for the AMD GPUs that came with the 2019 Intel Macs. Or I suppose there's also the possibility that it's actually fallen back to the iGPU which actually has a peak throughput of 384 GFLOPS.
