    As I understand, a BGA CPU cannot be delidded because it doesn't have a lid AKA IHS

    So why does an LGA CPU need a heatspreader (IHS) but the LGA doesn't?

    LGA CPUs are for desktops and there a LOTS of different types of heatsinks for desktops. To make it easier and for better stability for desktop coolers, an IHS is used.

    Also the pressure from big unwieldy desktop coolers can easily lead to cracked dies. The IHS helps distribute the weight.

    Also, let's not forget, due to the 'lower' power expectations of what BGA chips are designed for, part of that process is choosing a lower quality chip when they are binned. I believe @Papusan has articles or stats to back that up.

    Just hit up max overclocked BGA chips. And then compare the voltage needed vs. LGA chips with same overclock.
