WHY IS the Hash rate of 7840HS with DDR5 5600MEMS lower than which of 5800H DDR4 3200? about xmrig

What models of laptops exactly? Cooling and max power consumption have huge imact on CPU performance in laptops.

Hashrate depends most on the L3 cache size available, then on memory latency. These 2 CPUs have the same number of cores/threads and the same L3 cache size. But DDR4-3200 can have better latency than DDR5-5600 because of better timings.

5800H lenovo R9000P @ balance mode, 7840hs Beelink Mini PC @ TDP 65W,

My guess is that Legion of your have better cooling than Beelink and higher power limit but only way to determine it is to run xmrig and monitor temepratures and power consumption in HWInfo.
