iPhone Duo vs Galaxy Z Fold8 · Hong Kong
One of them still takes a SIM card.
In Hong Kong the Galaxy Z Fold8 accepts a physical nano-SIM and the iPhone Duo does not, in any market. Beyond that the two are closer than the marketing suggests: both reach 2x optical-quality zoom, and both pair two rear sensors of almost the same resolution.

Memory
Not published
12 GB
Apple has never published iPhone memory, and Xcode does not yet support the iPhone Duo, so there is no confirmed figure to print. Samsung states 12 GB.
BatteryNot comparable
44h
4800 mAh
Apple states battery as hours of video playback; Samsung states it as capacity in mAh. Neither converts into the other, and no ratio between them would mean anything.
ProcessorNot comparable

Octa-Core 4.74GHz, 3.6GHz
Apple publishes core counts and a chip name; Samsung publishes a clock speed. Comparing gigahertz across two different architectures says nothing about speed.
Why some rows refuse to answer
Two makers do not share a vocabulary or a measurement method, and each publishes the numbers on which it looks best. Where a pair of values are not two readings of the same quantity, this page shows both, says so, and declines to pick a winner. Refusing to answer is less satisfying than a verdict, and it is the only answer that will not mislead you.
