Going from the 6850U to 7840U was showing terrific generational uplift on the CPU side.

LuaRadio benchmark with settings of Test: Five Back to Back FIR Filters. Acer - Ryzen 7 7840U was the fastest.
LuaRadio benchmark with settings of Test: Hilbert Transform. Acer - Ryzen 7 7840U was the fastest.

With the Ryzen 7 7840U there also weren't any hybrid P/E core scheduling issues to worry about like there is with Alder Lake and Raptor Lake. Intel has been improving the hybrid scheduling on Linux but at times this MSI i7-1280P at least can exhibit some weird performance behavior.

LibRaw benchmark with settings of Post-Processing Benchmark. Acer - Ryzen 7 7840U was the fastest.
