Apple launched it’s M series of chips (Arm-based) precisely to get rid of Intel’s CPUs. Hard to beat the M series in power efficiency. Arm is more power efficient + Apple has an architectural license with Arm so they can tailor the architecture to their needs and make the chips super efficient.
They say there are 3 big foundries in the world. Tbh it’s more like two haha. Intel won’t improve until they spinoff their foundry division
