There's more to a computer than just the CPU ISA. While this particular thread is about the GPU, there is indeed "something different" about the M1 otherwise too. It is quite the non-standard SoC: unlike basically everything else (other than early Broadcom RPi crap) it even uses a custom Apple interrupt controller instead of the ARM GICv2/3. Also a custom IOMMU "DART" and a bunch of other peripherals. Very unusual: NVMe exposed as a plain hardcoded MMIO device (not enumerated over PCIe).
