    My opinion is that including trans people in this sort of study actually reduces the bias, because they’re the only people who will have experienced the social impacts of presenting both male and female at different times. All cis-gendered people will be inherently biased towards their own limited experience.







  • Yeah… chip designers have been battling heat output since silicon doping was invented. The main source of heat is transistors changing state, since it doesn’t happen instantly, and will disipate more heat when half-on, acting almost like a resistor.
    The higher the clock speed, the more time a transistor spends half-on. This is why things like undervolting and underclocking reduce power usage.
    Physically smaller transistors usually also means it takes less electrons to saturate the gate, so it allows lower voltages and currents to be used, while still toggling the state at the same speed. (Not to mention timing gets easier the closer the transistors are to each other)





  • That’s pretty much my understanding. Most of the advancements happened in memory speeds are related to the physical proximity of the memory and more efficient transmission/decoding.

    GDDR7 chips for example are packed as close as physically possible to the GPU die, and have insane read speeds of 28 Gbps/pin (and a 5090 has a 512-bit bus). Most of the limitation is the connection between GPU and RAM, so speeding up the chips internally 1000x won’t have a noticeable impact without also improving the memory bus.
