I got an identical version of VeraCrypt installed on 3 differently configured machines (hardware-wise). The OS is identical in all 3 cases, identically configured (all clones).
1. i7-6820hq with 32GB of RAM and Samsung 2TB 980Pro SSD
2. i7-10750H with 32GB of RAM and Samsung 2TB 970 Pro
3. i7-7820HQ with 16GB of RAM and Samsung 2TB 980 Pro
980 and 970 Pro are fairly new and close to latest-greatest but have been superseded by Samsung 990 Pro M.2 SSD with the Pascal controller. The speed difference is around 7000Mb/sec versus 9000mb/sec IIRC but in a lab environment, in real life you can't feel it.
The main system partition has been encrypted, it won't boot without decryption. I roughly timed decryption times. The first place goes to (2) i7-10750H and 3rd to i7-7820hq with i7-6820 essentially not much faster at 2nd place. The (2) choice is noticeably faster, I didn't time it precisely just yet but seemed to add just 20 seconds to decryption versus the other ones adding a full minute to 1.5 min to decryption. I will determine precise figures.
Seems like CPU speed is the main factor in decryption speed, contrary to my expectation of SSD speed being the main factor. I will re-run the tests once I add 32GB to (3) and see how it performs.
