  • Just because a CISC will run multiple instructions in a single clock cycle, it doesn’t automatically make it faster. Complex instructions means complex decode logic, that makes the execution slower, even at the same clock cycle. A modern intel CPU has something like 20+ stages of pipelining, while ARM has 3-5 stages, that makes the execution more energy efficient and more powerful. Also superscalar RISC architectures exist, so RISC can also execute more instructions at a time, and in less time.

    Lastly, modern x86_64 look like CISC, but are actually RISC under the hood, the single instruction is just a pseudo-instruction divided in multiple simpler instructions. I don’t believe thay makes it much more efficient.

    I’m not saying they are not killing birds, or mice, or small preys in general. Cats are predators and amongst the best. What I’m saying is that they are invasive only in places they never were in before human brought them (like Australia or small islands). In continental Eurasia (except areas where they are explicitly been controlled), they have always been there, and the environment is adapted to their presence and will not significantly suffer, not more than any other predator.

    In my experience it highly depends on the cat. Some are perfectly content with proper scratchers and toys inside, some just visibly suffer staying inside, it might help we are far from the busy city with plenty of green and huntable animals, but most of our cats spend ~80% of time outdoor during summer and ~30% during winter.

    “Outdoor cats” are just cats. They are not a domesticated species, hunting is their instinct, and should just not be introduced in places where they wreck havoc to the environment. Where they are endemic (Europe and continental Asia) they don’t cause troubles to the ecosystem
