If anyone does basic stuffs like regular web browsing, youtube watching, Ms Office, then does cache latency really matter if not gaming and photo/video editing?
I am telling about ram cache latency(CL)yes.
it truly depends on which cache you are referring to but generally speaking a cache is short term storage. the faster that storage the less time the CPU/GPU spends waiting for more data from slower sources HDD/SSD.
I use a RAM cache for my SSD and an SSD cache for my HDD's.
I am telling about ram cache latency(CL)CPU cache? For basic tasks, most probably the difference will be neglible.
