While I was playing, I didn't notice any problems with calculating MIPS, but maybe I just didn't pay enough attention to it. Regarding the frequency, I think this is how it should be, there is no point in releasing processors with severely low frequencies, this will not give a big advantage in consumption and production cost, instead reduce the size of the crystal, so modern processors have a 3GHz+ frequency with low consumption due to small crystals.
The Intel Core i7-13620H which was released 2023 has only a base clock of 2,4 Ghz.
And to my understanding is a reason why we stopped increasing it that much, is that the thermal load would get to high. Reason why we have gone with multi cores and bigger caches.
- Performance scaling with higher clock speeds has diminished over the years. While increasing clock speeds was once a simple way to improve performance, this method has become less effective. Modern processors are more complex, and simply increasing the frequency doesn't provide linear gains in real-world performance.
- Many tasks are bottlenecked by factors other than raw clock speed, like memory access, latency, bandwidth, or parallel processing limitations.
Architecture improvements: Rather than just increasing clock speed, modern CPUs focus on improving architecture. Techniques like out-of-order execution, pipelining, cache optimizations, and branch prediction help processors achieve better efficiency and performance at lower clock speeds
