ExFat slower on MacOS than APFS/MacOS Extended

SanDisk 1TB Extreme Portable formatted as ExFat only getting 753.3MB/s write and 666.5MB/s read using Thunderbolt3 cable? When formatted APFS/MacOS Extended the performance is in the +900MB/s.
When ExFat is plugged into my Windows device I’m getting +900MB/s.
