  • Aside from letting you cram more circuitry onto the same size chip, smaller transistors means you can get better power efficiency and reduce heat output.

    Basically, even if you just take an existing design and use it to make chips at a smaller node size, you get chips which run cooler and with less power. Those chips can then get you the same performance with better efficiency (e.g. same speed but better battery life), or you can crank up the speed so that you get more speed for the same amount of power as the original.

    And as mentioned above, because the transistors are smaller, you can fit more stuff onto the chip. So you can make even more complex chips which also still run more efficiently than their predecessors (both because of the direct power savings from using smaller transistors, and because designs become more efficient).



  • Yeah, I know it can be mismatched sizes, the laptop i’m typing this on has 4gb soldered + a 16gb DIMM. My question was more trying to understand why manufacturers seem to prefer using one of each rather than just making both replaceable, since the hybrid approach makes it only partly upgradeable while taking up as much physical space as if both slots used removable DIMMs. Since it seems like this combines all of the disadvantages of fully replaceable and fully soldered RAM with only half of an advantage, why are there so many laptops which do it?
