Question Dual high latency or single low latency

[Mawla]

Which memory will be faster - dual channel, higher latency or single channel, lower latency?
Example: DDR5 5600MHz - 2x8GB CL46 or 1x16GB CL36

If it depends on the application, please give examples.

Always duel channel as you're doubling your bandwidth

Always? I see this double bandwidth thing everywhere and I understand the principle. But how does it translate to real world performance?

Most side-by-side test results favour dual channel by up to ~10% in some cases; and by less than 1% in some. In a few cases, the single channel actually does slightly better.

Anyway, in all the tests I've seen, the RAM latencies are the same or unspecified. That's why I asked.
