Why Arn't CPU's Produced "Lapped"?

Why arn't CPU's automatically lapped before sale?
Surely this would take 10 seconds for a machine to complete?

Maybe I'm missing something, but it just seems an obvious thing to do :confused:

Even the horrendously concave E6600 C2Ds worked perfectly fine at stock without lapping. It's just additional unneeded expense for Intel.
 
Seeing as the majority of people do not overclock their cpu's, lapping each and every one would be a complete waste of time and money.
 
Personaly I don't know if I'd bother my self with lapping a cpu. Looks like a lot of hassel and am I right in saying that it's guaranteed to void your warranty as they can tell if its lapped?
 
Same reason why the TIM used with stock CPUs/GPUs is crap. It serves the purpose and is cost effective.

It never ceases to amaze me how overclockers still haven't quite yet realised that they represent about .001% of the overall market. :D
 
because the average computer user would want the savings not having the cpu lapped by the manufacturer. Although it makes you wonder why they don't do a lapped enthusiast addition

Them Extreme versions of chips in my book should all come lapped and have a pure copper plate.. For the money you have to pay for them they should be perfect in every way.
 
The question should be why do they put heatspreaders on the cores to begin with, older processors just used to have the bare core so with a decent heatsink you got optimum heat transfer.

You can have the best thermal compound/heatsink in the world but if the transfer between core and heatspreader is poor you're going to get hot temps, maybe it's something they do to hinder overclocking. :confused:

It's to protect the CPU cores, much harder to damage them with a heatspreader on the top.
 
Proper lapping takes time. Its dirty, produces very very fine metal particles. These can get into the CPU, affect reliability and require more money to clean the CPU. Its an exotic unneeded process!
 
That is one of the reasons for thermal paste, helps to transfer heat and stops the need for the surfaces to be perfectly flat as it bridges the gap.

Another reason why people shouldn't put a thin layer of TIM over the CPU headspreader if it's unlapped. You should get better results by letting the HSF spread the thermal paste.
