First lets review what a Fusion Drive is: The work fuseword 'fuse' give us a clue here, we are linking (fusing) two discrete drives within the OS so they are seen as one.

In this case a SATA III (6.0 Gb/s) traditional spinning hard drive and either a PCIe 2.0 x 4 lane NVM-Express blade SSD (in the current model) or in the previous model a PCIe 2 lane blade SSD.

For a comparison here is a benchmark between them:
 
* 2014/Mid 2015 iMac 5K: writes at ~716 MB/sec and reads at ~766 MB/sec.
* Late 2015 iMac 5K: writes at ~1520 MB/sec and reads at ~2080 MB/sec.
 
While the benchmark shows the faster 4 lane PCIe NVM interfaced SSD is faster than the older 2 lane PCIe. The width of the connection has a lot to do with it (2 vs 4 lanes).
 
To be clear here you can't use the newer SSD in the older system the system does not offer a 4 lane PCIe interface.
