Why are you still doing Geekbench 5.4 benchmark and not Geekbench 6? Geekbench 6 is specifically geared at comparing performance of last gen CPUs.
Can you share the command line (setting) when you do the DiskSpd stress test ?
I would like to do the same stress test but don't know how to stress it like you did between this gen and last gen XPS9320.
Please add Cinebench2024/Geekbench6 benchmark tool test, they will be good for latest CPU.
