Because having many cores means your processor can do many things at once. Having a high clock speed means doing something faster. I don’t run many things that can use more than 1 thread when I’m on battery anyway, and having the the extra cores running is just wasted battery, especially since they are crippled and running at 800MHz because of a governor. With just 1 processor running at up to 3.4GHz, and hyper-threaded to work to work like a dual core, I can have full performance as long as I don’t do something that slams all threads at once, and even if I do, that one core will give it’s all.
I recently helped a guy in here with a 6 core, hyper-threaded,very fast cpu and some nvidia gpu who was complaining that his game was lagging badly in Garuda but not in Ubuntu. I noticed in his inxi that he had his badass cpu throttled by the powersave governor and topping out at only 1GHz. It doesn’t matter how many cores you have when most things only use 1 thread. What matters is the speed.
Here’s the post I’m talking about…
