Int16 vs float32 performance

The first: converts int16 to float32, and then do division inplace. This would require at least two passes over the memory. The second: uses divide directly and specifies an out-array that is in float32. Theoretically this should do only one pass over memory, and thus be a bit faster. My questions: Does the second way use float32 for ...

NettetA torch.finfo is an object that represents the numerical properties of a floating point torch.dtype, (i.e. torch.float32, torch.float64, torch.float16, and torch.bfloat16 ). This is similar to numpy.finfo. The number of bits occupied by the type. The smallest representable number such that 1.0 + eps != 1.0. Nettet29. jun. 2024 · In general, the closer the approximation, the less performance decay you can expect. If you quantize everything to float16, you cut the memory in half and probably you won’t lose accuracy, but won’t really gain speedup. On the other hand, quantizing with int8 can result in much faster inference, but the performance will probably be worse.
