Hi,

I would like to know if the 1080 (GP104) has the INT8 x4 speedup versus FP32.
and what are the differences between 1080 and 1080ti ?

Thanks,
Mohamed

Yes, both have it. It is a characteristic of the cc6.1 compute capability (so all cc6.1 devices have this 4xFP32 rate for int8 operations, when those operations take advantage of the dp4a instruction.)
