Look at the L1 L2 L3 cache. Many people underestimate this

here are two examples from different pcs

# lscpu | grep cache
L1d cache:           16K
L1i cache:           64K
L2 cache:            2048K
L3 cache:            8192K


# lscpu | grep cache
L1d cache:           32K
L1i cache:           32K
L2 cache:            256K
L3 cache:            6144K
