iMac startup drive shows its capacity as 1.03 TB, indicating the presence of an extra 32 GB on top of the standard 1 TB. The previous model's SSD portion of the Fusion drive was 24 GB, 32 is better.
For what it's worth, the average Geekbench 4 multi-core score for this iMac is 12800-ish. Mine scored 13525.
Looks like it'll take about 90 minutes to transfer the info & settings to the iMac.
In a nice touch the mouse & keyboard supplied with the new iMac come already paired up.
@kdfrawg Never struck that before. I did buy a MBP in 2009, exactly one week before Snow Leopard came out. Because it was a recent enough purchase, I scored the update for $15.
Thunderbolt 3-to-Thunderbolt 2 adaptor in use to connect a Thunderbolt 1-SATA drive dock that's carrying the SSD extracted from the dead MBP.
