I think all of the ones listed as DirectX 10.1 or lower on this page: https://en.wikipedia.org/wiki/Feature_levels_in_Direct3D

Those are all quite old now of course, but even modern GPUs may not have 64-bit ALUs and rely on emulation instead. Intel Gen11 in Ice Lake, for example: https://01.org/sites/default/files/documentation/intel-gfx-p...

In mobile architectures 64-bit ALUs can be an optional feature that is omitted for lower end configurations. I know this is true of PowerVR.
